PART I

Item 1. Business.

Overview

Capstone Green Energy Corporation (“Capstone”, “We” or the “Company”) is a provider of customized microgrid solutions and on-site energy technology systems focused on helping customers around the globe meet their environmental, energy savings, and resiliency goals.  In April 2021, we added additional products to our portfolio and shifted our focus to four key business lines. Our Energy Conversion Products business line is driven by the Company’s industry-leading, highly efficient, low-emission, resilient microturbine energy systems offering scalable solutions in addition to a broad range of customer-tailored solutions, including hybrid energy systems and larger frame industrial turbines. Through our Energy as a Service business line, we offer rental solutions utilizing our microturbine energy systems and battery storage systems, comprehensive factory protection plan service contracts that guarantee life-cycle costs, as well as aftermarket spare parts. Our two emerging business lines are Energy Storage Products and Hydrogen Energy Solutions. Our Energy Storage Products business line designs and installs microgrid storage systems creating customized solutions using a combination of battery technologies and monitoring software. Through our Hydrogen Energy Solutions business line, we offer customers a variety of hydrogen products, including the Company’s microturbine energy systems. Because these are new offerings, Energy Storage Products and Hydrogen Energy Solutions revenue has been immaterial to date.

We develop, manufacture, market and service microturbine technology solutions for use in stationary distributed power generation and distribution networks applications, including energy efficient cogeneration combined heat and power (“CHP”), integrated combined heat and power (“ICHP”), and combined cooling, heat and power (“CCHP”), as well as renewable energy, natural resources, and critical power supply applications. Microturbines allow customers to produce power on-site in parallel with the electric grid or stand-alone when no utility grid is available. Several technologies are used to provide “on-site power generation” (also called “distributed generation”) such as reciprocating engine (also known as internal combustion engines), solar photovoltaic power (“PV”), wind turbines and fuel cells. Microturbines can be interconnected to other distributed energy resources to form “microgrids” (also called “distribution networks”) located within a specific geographic area and provide power to a group of buildings. For customers that do not have access to the electric utility grid, microturbines provide clean, on site power with fewer scheduled maintenance intervals and greater fuel flexibility than competing technologies. For customers with access to the electric grid, microturbines provide an additional source of continuous on-site power generation, thereby providing additional reliability and potential cost savings compared to the local utility. With our stand-alone feature, customers can produce their own energy in the event of a utility power outage and can use microturbines as their primary source of power for extended periods of time unlike traditional diesel standby generator sets. Because our microturbines also produce clean, usable heat energy, they provide economic advantages to customers that can benefit from the use of hot water, chilled water, air conditioning and steam. In addition, our microturbines have been used as battery charging generators for hybrid electric vehicles and to provide power to a vessel’s electrical loads in marine applications. Our microturbines are sold, installed and serviced primarily through our global distribution network. Together with our distributors, we offer new and remanufactured parts as well as a comprehensive factory protection plan through long-term service agreements ranging from 5 to 20 years. We also offer our microturbines for rent through our long-term rental program. In addition to our existing microturbine products, we offer additional energy conversion products in the form of Baker Hughes 5 MW, 12 MW, and 16 MW industrial gas turbines, where we will purchase and resell their product. The Company is currently exploring energy conversion options for the smaller end of the power spectrum.

We offer microturbines designed for commercial, industrial and onshore and offshore oil and gas applications with product offerings ranging from 30 kilowatts (“kW”) to one megawatt (“MW”) in electric power output, which can be deployed in arrays up to 10 MWs. Our microturbines combine patented air bearing technology, advanced combustion technology, sophisticated power electronics, and advanced software controls to form efficient and ultra-low emission electricity and cooling and heat production systems. Because of our air bearing technology, our microturbines do not require lube oil, grease, or traditional coolants. This means they do not require routine maintenance to change and dispose of lube oil, grease, or other liquid lubricants, as do the most common reciprocating engines.

Table of Contents

We also manufacture and supply controllers that provide complete automated system control, including electrical load following and custom logic to protect against expensive local utility demand charges. These controllers include the legacy Capstone Logic Controllers (CLC) and the new Capstone PowerSync family of system controllers.

Beginning Fiscal 2022 we intend to begin manufacturing modular hybrid energy stations and lithium-ion battery energy storage systems (“BESS”) to be sold either individually or combined as part of a custom microturbine-battery storage solution.

​

Our microturbines can be fueled by various sources, including natural gas, propane, butane, various sour gases, renewable fuels such as renewable natural gas, landfill gas, biogas or digester gas, kerosene, diesel and biodiesel. Our microturbines are available with integrated unit mounted heat exchangers, making them easy to engineer and install in applications where hot water, chilled water, air conditioning and steam is desired. Alternative fuels, in particular hydrogen, are increasingly important and the Company recently demonstrated that it could reliably run on a 10% hydrogen / 90% natural gas mix and is currently testing a 70% hydrogen / 30% natural gas mix through its R&D partnership with Argonne National Laboratory. These are promising milestones on the development roadmap to 100% hydrogen solutions.

We estimate that over the last three years, we have helped save companies approximately $700 million on energy costs and over one million tons of carbon.

Our microturbines are sold primarily through distributors and Original Equipment Manufacturers (“OEMs”). Distributors purchase our products for sale to end users and also provide service, application engineering and installation support. Distributors also provide a variety of additional services, including engineering, application, and air permit support services in which the microturbines will be used, installation support of the products at the end users’ sites, commissioning the installed applications and providing post commissioning service, including a comprehensive FPP. Our distributors perform as independent value-added resellers. OEMs integrate our products into their own product solutions.

This Annual Report on Form 10-K (this “Form 10-K”) refers to our fiscal years ending March 31 as “Fiscal” years.

Company Response to COVID-19

In March 2020, the Company began to monitor the global effects of COVID-19, the worldwide spread of which led the World Health Organization (“WHO”) to characterize it as a pandemic on March 11, 2020. Thereafter, most U.S. states imposed “stay-at-home” orders on their populations to stem the spread of COVID-19. Of specific interest to the Company, stay-at-home orders were imposed in the state of California on March 20, 2020.

On March 23, 2020 we enacted a Business Continuity Plan in response to COVID-19. Beginning March 30, 2020, we furloughed 52 employees, leaving behind only staff deemed essential for day-to-day administrative operations for a minimum period of 45 days. Our Leadership Team volunteered to take a 25% temporary salary cut. In addition, 25 other top Company managers volunteered to take a similar 15% reduction in salary. Several employees returned to work June 1, 2020, most with the 15% voluntary salary cuts, with others scheduled to return in a staggered manner through to the end of September. Additionally, in March 2020, the Board voted to take a temporary 25% reduction in base cash retainer in support of our Business Continuity Plan. As a result of the continued global economic slowdown due to COVID-19 and the associated decline in global crude oil prices, we eliminated 26 positions on June 1, 2020. During the period of March 30, 2020 to June 1, 2020, we had a limited production capability of new microturbine products but had pre-built approximately 5.9 MW of microturbine finished goods during March 2020 for shipment during this period of suspended production. On September 28, 2020 salaries were returned to 100% and remaining furloughed employees returned to work. Our vendor supply chain has been impacted by the pandemic; however, we have been able to maintain sufficient supply flow to continue operations as of the date hereof.

On March 27, 2020, President Trump signed the Coronavirus Aid, Relief and Economic Security (the “CARES Act”), which, among other things, outlines the provisions of the Paycheck Protection Program (the “PPP”). The Company determined that it met the criteria to be eligible to obtain a loan under the PPP because, among other reasons, in light of the COVID-19 outbreak and the uncertainty of economic conditions related thereto, the loan was necessary to support the

Company’s ongoing operations. Under the PPP, the Company could obtain a U.S. Small Business Administration loan in an amount equal to the average of the Company’s monthly payroll costs (as defined under the PPP) for calendar 2019 multiplied by 2.5 (approximately 10 weeks of payroll costs). Section 1106 of the CARES Act contains provisions for the forgiveness of all or a portion of a PPP loan, subject to the satisfaction of certain requirements. The amount eligible for forgiveness is, subject to certain limitations, the sum of the Company’s payroll costs, rent and utilities paid by the Company during the eight-week period beginning on the funding date of the PPP loan.

 On April 24, 2020, the Company closed on a PPP loan in the amount of $2,610,200, which was transferred by the Company into an account dedicated to allowable uses of the PPP loan proceeds. On May 13, 2020, the Company repaid $660,200 of the loan in accordance with the Fourth Amendment to the Note Purchase Agreement between the Company and Goldman Sachs Specialty Lending Group, L.P. In February 2021, the Company applied for forgiveness in full of the original balance of the PPP loan and is awaiting review and approval. No assurance can be provided that forgiveness of any portion of the PPP loan will be obtained.  

Products

Our 30 kW (“C30”) microturbine can produce enough electricity to power a small convenience store or cathodic protection for an oil or natural gas pipeline. Our 65 kW (“C65”) microturbine can produce enough heat to provide hot water to a 100 room hotel while also providing about one third of its electrical requirements. Our 200 kW (“C200”) microturbine is well suited for larger hotels, office, commercial, and industrial buildings and wastewater treatment plants, among others. By packaging the C200 microturbine power modules into single enclosures which are available in multiple sizes and are built in similar dimensions to a standard shipping container or International Organization for Standardization sizes, we have created an upgradable family of microturbine offerings from 400 kW up to 1000 kW or 1 MW in a compact footprint engineered to function as a single source of power. Our 400 kW, 600 kW, 800 kW and 1000 kW (“C1000S Series”) microturbines are well suited for utility substations, larger commercial and industrial facilities and remote oil and gas applications. Our 600 kW and 800 kW systems can be shipped in a five-bay configuration which allows the end-use customer to add one to two more 200 kW microturbines in the future to increase their total onsite power production from 600 kW to 1000 kW without any change to the existing site footprint, as the customer’s business power demands expand over time.

Our microturbines are compact, lightweight and environmentally friendly generators of electricity and heat compared to competing technologies. They operate on the same principle as a jet engine using a variety of commercially available fuels. For example, our microturbines can operate on low British Thermal Unit (“BTU”) gas, which is gas with lower energy content, and can also operate on gas with a high amount of sulfur, known in the industry as sour gas. Examples of these fuel sources include methane from facilities such as wastewater treatment plants, landfills and anaerobic digesters. Our microturbines’ multi-fuel capability provides competitive advantages with respect to some of our selected vertical markets. The combustor system remains the same for all fuels except for the fuel injectors, which currently vary between liquid and multiple gaseous fuels.

Our microturbines incorporate four major design features: advanced combustion technology, patented air bearing technology, digital power electronics and proprietary remote monitoring systems.

Table of Contents

Our electronic controls manage microturbines using our proprietary software and advanced algorithms. The controls start the turbogenerator and manage its load, coordinate the functioning of the microturbine with the grid, manage the speed, fuel flow and exhaust temperature of the microturbine, convert the variable frequency, up to a maximum of 1,600 Hertz and variable voltage power produced by the generator into a usable output of either 50 or 60 Hertz AC for stationary applications or DC for hybrid electric vehicle applications, and provide digital communications to externally maintain and control the equipment.

The electrical output of our units can be paralleled in multiple unit configurations through our Advanced Power Server product and a digital communications cable to serve larger installations requiring electrical loads of up to ten megawatts. Our products can operate connected to the electric utility grid as a current source, on a standalone basis as a voltage source, multipacked to support larger loads as a “virtual single” unit and in dual mode, where the microturbine operates connected to the electric utility grid or operates independently.

We were the first microturbine manufacturer to achieve UL Class I, Division 2 certification and ATEX certification for operation in hazardous area oil and gas applications. These specially packaged systems are applied in oil and gas production areas with potentially explosive environments. Our C65, as well as our C200 and C1000 Signature Series grid connect and stand-alone microturbines are listed by Underwriters Laboratories (“UL”) as meeting the UL 2200 stationary engine generator standards and the UL 1741 utility interconnection requirements.

Our C30 and C60 microturbines are certified by the California Energy Commission and were the first products to comply with the requirements of its “Rule 21” grid interconnection standard. This standard streamlines the process for connecting distributed generation systems to the grid in California. The benefits of achieving this standard include avoiding both costly external equipment procurement requirements and extensive site by site and utility by utility analysis. Our protective relay functionality has also been recognized by the State of New York, which allows our microturbines to be connected to New York’s electric utility grid.

We offer various accessories for our products including rotary gas compressors with digital controls, integrated heat recovery modules for CHP applications, dual mode controllers that allow automatic transition between grid connect and stand-alone modes, batteries with digital controls for stand-alone or dual mode operations, power servers for large multipack installations, protocol converters for Internet access, packaging options and miscellaneous parts such as frames, exhaust ducting, backflow dampers and installation hardware.

In addition to our existing microturbine products, we offer additional energy conversion products in the form of Baker Hughes 5 MW, 12 MW, and 16 MW industrial gas turbines, where we will purchase and resell their product. The Company is currently exploring energy conversion options for the smaller end of the power spectrum.

During Fiscal 2022, we intend to begin manufacturing modular hybrid energy stations and lithium-ion BESS to be sold either individually or combined as part of a custom microturbine-battery storage solution.

Applications

Stationary power generation applications can vary greatly depending on load size and demand location. From small 2 kW back-up generators to several large 1,000 MW central generating facilities, stationary power systems can offer superior fuel efficiency for the customer while also meeting strict emissions regulations. Historically, power generation in developed countries such as the United States has been part of a regulated utility system. However, a number of developments related primarily to the deregulation of the utility industry as well as significant technology advances have helped to broaden the range of power supply options available to interested parties.

Our full line of microturbine energy solutions target multiple vertical markets worldwide, including energy efficiency, renewable energy, natural resources, critical power supply, microgrid and transportation. Within these vertical markets, we focus on applications that we believe have the greatest near-term potential for the customer based on various different factors such as energy load demand, available fuels, economic payback and for some, government incentives. The critical power supply, microgrid and transportation verticals do not currently generate significant revenues for us, however, we have experienced continued development in these verticals and remain focused on the development of applications in these verticals. We also target smaller sub segments that fall within these vertical markets that may not otherwise be considered for on-site generation.

Energy Efficiency—CHP/CCHP

Energy efficiency refers to the proper utilization of both electrical and thermal energies in the power production process. In such applications, our microturbines are able to maximize the availability of usable energy which we believe provides a significant economic advantage to our customers while reducing their onsite emissions. CHP and CCHP can improve site economics by capturing the waste heat created from a single combustion process to increase the efficiency of the total system, from approximately 30 percent to approximately 85 percent for hot water and chilled water to as much as 90 percent or more for some steam and direct drying applications. Compared with more traditional, independent generation sources, the increase in operational efficiency also reduces greenhouse gas emissions through the displacement of other separate systems, which can also reduce operating costs.

When compared to onsite boilers, microturbines generally produce fewer commonly found air pollutants (“criteria pollutants”), such as nitrogen oxides (“NOx”), carbon monoxide (“CO”) and volatile organic compounds (“VOCs”). In fact, our CHP or CCHP system can displace local boiler emissions altogether. A high efficiency CHP or CCHP system can allow for reduced net utility costs for end users as well as improved fuel consumption. The most common uses for captured thermal energy include space heating and air conditioning, water heating and water chilling, direct-drying and steam for industrial applications. In CCHP applications, the microturbine exhaust drives an absorption chiller, which produces the chilled water necessary for air conditioning and local use. Organizations of all sizes have used the heat generated by our microturbines at the many different types of commercial and industrial applications they serve, including hotels and resorts, hospitals, and medical centers, as well as office buildings and large retail facilities.

During Fiscal 2021, we continued to expand and develop our new hydrogen products. We released our first commercially available hydrogen-based Combined Heat and Power (CHP) product, which can reliably run on a 10% hydrogen-90% natural gas mix, and we are targeting a commercial release of a product that will run on a 30% hydrogen-70% natural gas mix product by March 31, 2022. We are continuing our research and development partnership with Argonne National Laboratory and are already testing a 70% hydrogen-30% natural gas configuration. Argonne National Laboratory is a national science and technology research laboratory operated by the University of Chicago Argonne, LLC for the United States Department of Energy. In addition, in May 2021, we announced a demonstration project with Blue Economy CRC, a cooperative research center in partnership that was established to bring together sustainable seafood production and renewable energy to further develop Australia’s aquaculture industry. This demonstration microturbine system is intended to run on 100% hydrogen.

Renewable Energy

​

There is a growing transition to renewable energy sources and technologies on a global scale. Our microturbines run efficiently on renewable fuels such as methane and other biogases from landfills, wastewater treatment facilities and renewable natural gas.  They also run efficiently on other small biogas applications like food processing plants, livestock farms and agricultural green waste operations. Microturbines can burn these renewable fuels with minimal emissions, thereby, and in some cases, avoiding the imposition of penalties incurred for pollution while simultaneously producing electricity from this “free” renewable fuel source for use at the site or in the surrounding areas. Our microturbines have demonstrated effectiveness in these smaller applications and may outperform conventional combustion engines in some situations, including when the gas contains a high amount of sulfur, as the sulfur can contaminate combustion engines lube oil leading to equipment breakdowns and higher lifecycle costs.

​

We offer C65 and C200 stand-alone digester products to the renewable energy market segment. With these products, we are able to target many different types of renewable energy applications, including biogas producing facilities in third world countries and in remote locations that offer a valuable fuel source for the generation of electricity. The performance of our C65 digester gas system has been routinely evaluated to ensure that the combustion system is stable from 0 to 100 percent power output. Minor controls changes have been implemented to increase stability at low power levels. The ability to convert this low BTU fuel to electricity along with the high reliability and low maintenance features of this product make it well suited for this market segment.

Natural Resources—Crude Oil, Natural Gas, Shale Gas & Mining

Our microturbines are installed in the natural resource market for use in both onshore and offshore applications, including exploration, production, compression, and transmission sites as a highly efficient and reliable source of prime power. In some cases, these oil and gas or mining operations have no electric utility grid and rely solely on power generated onsite. There are numerous locations, on a global scale, where the drilling, production, compression and transportation of oil and gas and other extraction and production processes create fuel byproducts, which are traditionally burned or released into the atmosphere. Our microturbines can turn these fuel byproducts, flare gas or associated gas, into a useable fuel to provide power to these remote oil and gas sites.

The addressable market for our microturbines in the United States shale reserves industry is significant. The shale gas market for microturbines may grow as demand for natural gas continues to rise and the U.S. as the Environmental Protection Agency (“EPA”), the Department of the Interior and other federal and state agencies work to reduce the emission of hazardous air pollutants associated with natural gas development, including limitations on the flaring of excess gases. Our product sales in the natural resources market are driven by our microturbines’ reliability, emissions profile and ease of installation. However, any growth in the oil and gas sector within our natural resources market is primarily driven by oil prices.

The C30, C65 and C200 microturbines can be configured to meet Class 1 Zone 2 hazardous location requirements for the natural resources market. Hazardous location requirements are met through package ventilation changes for purging and pressurizing package air to avoid potential flammable mixtures as well as controls for emergency disconnect of fuel and electrical sources. The package is upgraded to stainless steel construction to withstand the often corrosive offshore environments where these units are installed. Oil and gas customers often prefer power generation systems that offer low maintenance and high reliability in order to ensure continued production.

Critical Power Supply

Because of the potentially catastrophic consequences of system failure, momentary or otherwise, certain high demand power users, including high technology, health care and information systems facilities require higher levels of reliability in their power generation service. The majority of microturbine based distributed generation installations have powered through hurricanes with little or no downtime. To meet these customer requirements, traditional solutions utilize Uninterruptible Power Supplies (“UPS”) to protect critical loads from power disturbances along with back-up diesel generators for extended outages. We offer an alternative solution that can both meet customer reliability requirements and reduce operating costs.

Table of Contents

We have developed the world’s only microturbine-powered UPS solutions that offer clean, IT grade power and can completely displace the need for traditional UPS and back-up diesel generators. We offer two UL listed microturbine powered UPS solutions: our Hybrid UPS microturbine-powered solution, which provides power when dispatched in high efficiency, standard UPS and emergency power. These integrated solutions are well suited for new facility construction or expansion and can be installed with absorption chillers or other heat recovery systems to obtain high efficiency levels while reducing operating costs, compared with traditional solutions.

Dual-mode units operating in a prime power configuration can support a 150 percent overload for up to 10 seconds during transient conditions. Dual-mode units operating in grid parallel mode can provide customers a back-up power system with an economic return. These systems offer high on-site energy efficiency when combined with a heat exchanger (CHP) to create hot water, or with a chiller (CCHP) for air conditioning at these facilities. This configuration, when combined with our Dual Mode Controller, can transition from the grid parallel mode to prime power mode in less than 10 seconds. Our microturbines can also be installed along with a rotary UPS to provide a complete line interactive continuous power solution. In this case, the microturbines remain in grid connect mode while the rotary UPS stabilizes the utility voltage and provides a seamless transfer from operation connected to the grid to operation isolated from the grid.

Microgrid

A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable energy entity with respect to the grid. Distributed energy resources typically include other dual-mode microturbines, reciprocating engines, PV, wind turbine, fuel cells and battery storage.  Microgrids can be connected to larger electricity grids; however, in the event of a widespread outage, the microgrid will disconnect from the main grid and continue to operate independently to maintain the electricity supply to the homes and businesses that are connected to the microgrid’s electricity network. Our microturbines have the ability to meet the needs of microgrid end-users by lowering their overall cost to operate and by providing a versatile dispatchable technology that is fuel flexible and scalable enough to fit a wide variety of applications.

Additionally, we have our own programmable logic control system and sensors, which interface with other building automation systems and are a key aspect of monitoring a microgrid. The use of microgrids to serve local loads helps to reduce energy losses in transmission and distribution, further increasing the efficiency of the microgrid. We have been a part of numerous successful microgrid installations worldwide ranging from a wind turbine manufacturer, ski resort, university, industrial farm, utility software company, brewery and electrical distribution utility. Our microturbines’ functionality is to ensure energy availability for advanced microgrids before and during disasters, such as hurricanes. They may also help reduce electrical expenditures in the years following a disaster when electric utility rates may be increased to pay for the expenses for grid infrastructure repairs and improvements associated with these disasters.

Transportation

Our technology can also be used in hybrid electric vehicle (“HEV”) applications. Our customers have applied our products in HEV applications such as transit buses and Class 7 and 8 work trucks. In these applications, the microturbine acts as an onboard battery charger to recharge the battery system as needed. The benefits of microturbine-powered HEV hybrids include extended range, fuel economy gains, quieter operation and reduced emissions when compared with traditional internal combustion engines. Internal combustion diesel engine manufacturers have been challenged for the last several years to develop technology improvements, prior to aftertreatment that reduce emissions to levels specified by the EPA and CARB 2007 and 2010 standards. Many manufacturers are incorporating aftertreatment that increases upfront equipment costs, vehicle weight and life cycle costs, and may reduce overall engine efficiency.

Additionally, our technology is also used in marine applications. Our customers have applied our products in the commercial vessel and luxury yacht market segments. The application for our marine products is for use as a ship auxiliary generator set. In this application, the microturbines provide power to the vessel’s electrical loads and, in some cases, the vessel is able to utilize the exhaust energy to increase the overall efficiency of the application, reducing overall fuel consumption and emissions. Another feasible application is similar to our HEV application where the vessel is driven by an electric propulsion system and the microturbine serves as an on board battery charger and range extender. Our marine customers use both liquid fueled and natural gas microturbine products. Vessel owners can receive the same benefits as

users of stationary products: low emissions with no exhaust after treatment, long maintenance intervals, high reliability, low noise and no vibration. In Fiscal 2020 and Fiscal 2021, transportation products were only for customer demonstrations.

Sales and Marketing

We primarily sell and market our microturbine product, parts and service through our global network of authorized distributors and a new direct sales team, which was formed in January 2020 to focus on OEMs and national accounts.

In January 2020, we divided our sales and marketing team into two separate organizations. One organization remains focused on developing and managing our existing worldwide distribution channel and leading all marketing and advertising activities as we continue building our Company into a strong and recognizable worldwide brand. The second organization is responsible for growing our Company's national account business and long-term rental fleet. Under the terms of the A&R Note Purchase Agreement with Goldman Sachs, we are required to grow our rental fleet to 21.1 MW, from our current fleet size of 10.6 MW, by March 31, 2022. Additionally, this team is responsible for business development, licensing, new product partnerships, and new fuels, such as hydrogen, and further growing our renewable market segment participation. We believe this sales strategy better enables us to capture market share with large, global customers, where we see greater potential at dozens of their facilities worldwide. Our existing distribution network remains our worldwide feet-on-the-ground and our local presence, while the internal salesforce will build strong, long-term relationships with larger, more diverse customers.

Our worldwide distribution network was developed from the ground up and has become a valuable asset, because we can reach end use customers globally. Each of our distributors is a strategically placed independent partner that markets, sells, and provides applications engineering support for our products on our behalf. In addition, distributors provide remote monitoring services, warranty support, local spare parts support, and customer training and long-term service support. Through our global distribution network, we offer a comprehensive factory protection plan (“FPP”) for a fixed fee to perform regularly scheduled and unscheduled maintenance as needed. We provide factory and onsite training to certify all personnel that perform sales, applications, commissioning, and long-term service on our microturbines. Individuals who are certified are called Authorized Service Providers, and must be employed by a distributor or an end user in order to perform work pursuant to a FPP. To assure proper application and installation of our microturbine systems, we offer an installer training and an application engineering certification program. We offer to assist all customers by reviewing their installation designs in relation to the technical requirements for proper operation of our products, such as electrical interconnections, load requirements, fuel type and pressure, cooling air flow and turbine exhaust routing. As part of the microturbine commissioning process, we also receive a checklist to confirm that the final installation adheres to our technical requirements before we accept our standard manufacturer warranty obligations. Our typical terms of sale include shipment of the products with title, care, custody, and control transferring at our dock, payment terms ranging from full payment in advance of shipment to payment in 90 days, and warranty periods of approximately 15 to 24 months from shipment depending on the product type. We typically do not have customer acceptance provisions in our agreements.

Our Distributor Support System (“DSS program”) provides additional support for distributor business development activities, customer lead generation, brand awareness and tailored marketing services for each of our major geography and market verticals. This program is funded by our distributors and was developed to provide improved worldwide distributor training, online documentation library, paperless service software, sales efficiency, website development, company branding and funding for increased strategic business-to-business marketing activities.

Our Geographic Markets

United States and Canada

We have distribution agreements with several companies throughout North America for the resale of our products. Many of these distributors serve multiple markets in their select geographic regions. The primary markets served in this region have been energy efficiency, renewable energy, and natural resources products. The energy efficiency and natural resources vertical markets are expected to grow as a result of an increased domestic production of hydrocarbons, the low downstream price of natural gas, as well as public and regulatory acceptance of distributed generation.

Table of Contents

In developing our sales opportunities, we have identified the need to address various requirements present in our target localities. These requirements include electric grid interconnection standards, gas utility connection requirements, emissions standards, building and fire safety codes and various inspections and approvals. The costs and scheduling ramifications of these various approvals, in conjunction with normal bidding process requirements and construction delays, can be significant to the completion of an installation. Our goal is to work with the applicable regulating entities to establish compliant standards for the installation of our microturbines so that the costs and installation timelines are minimized for our customers.

Latin America

Our target markets in Latin America are energy efficiency, renewable energy, and natural resources. Oil and gas production projects continue to be a growing market in Latin America.

Energy reform in Mexico, for example, has opened new market opportunities for us by allowing competition among multiple players and enabling power generation companies to sell directly to consumers instead of only to the state-owned Federal Electricity Commission. Our strategy is to leverage our distribution network in Mexico across various market verticals.

South America constitutes a diverse group of markets that vary greatly in potential capture for us based on several factors, including availability of oil and gas production and transmission, energy pricing and political and investment climate. While we have distributors in nearly all South American countries, management is focused on what we consider to be the top national markets, which include Colombia, Brazil, Bolivia, and Chile.

Asia and Australia

Our target markets in Asia and Australia are energy efficiency, renewable energy, and natural resources. Our historical sales in Southeast Asia and Australia have primarily been in the energy efficiency and the oil and gas markets. Other areas in Asia and the Pacific Rim offer attractive opportunities as well. China is expected to see growth in the oil and gas market, while biogas recovery is showing signs of growth in Southeast Asia.

Middle East and Africa

Our target market in the Middle East and Africa is primarily oil and gas. This includes flare gas to power projects which are a particularly attractive market opportunity given the volume of gas being flared, and the need for stable power in the region. Management has targeted distributors and customers involved in the capture and use of flare gas in the oil and gas market. However, the geopolitical environment in this region is still volatile, which can have an impact on our sales.

Europe and Russia

To address the European market, including Russia, we are strengthening our relationships with existing and new distributors and have increased local sales and service support. We have an office in the United Kingdom for the purpose of working with our local distributors on a daily basis to identify and understand growth opportunities. Upon the successful resolution of Brexit, we have recently upgraded our Integrated Remanufacturing Facility (IRF) in the United Kingdom to make new and remanufactured parts readily available to our distributors. Europe has a history of extensive use of distributed generation technologies. We continue to diversify the Company’s overall presence in Russia and the surrounding Commonwealth of Independent States (CIS) as we explore new growth opportunities in these areas with multiple new distributors. The rebuilding of our business in Russia and the surrounding CIS area continues to evolve including the addition of our new Russia oil and gas distributor Arman Energo. Further, the continuation or escalation of geopolitical instability in Russia and Ukraine could continue to negatively impact our operations, sales, and future growth prospects in that region.

Customers

Sales to Cal Microturbine (“CAL”) and E-Finity Distributed Generation, LLC (“E-Finity”), our domestic distributors, accounted for 15% and 12%, respectively, of our revenue for Fiscal 2021. Sales to E-Finity accounted for 12% of our revenue for Fiscal 2020. Additionally, E-Finity accounted for 13% and 14% of net accounts receivable as of March 31, 2021 and March 31, 2020, respectively.

We recorded net bad debt recovery of approximately $0.2 million during Fiscal 2021. We recorded net bad debt expense of approximately $0.4 million during Fiscal 2020 primarily due to the uncertainty of collections from certain distributors at the initial onset of the COVID-19 pandemic.

Competition

The market for our products is highly competitive. Our microturbines compete with existing technologies such as reciprocating engines and compete with emerging distributed generation technologies, including solar-powered systems, wind-powered systems, fuel cells and other microturbines. Many potential customers rely on the utility grid for their electrical power. Many of our distributed generation competitors are large, well-established companies that derive competitive advantages from production economies of scale, worldwide presence, brand recognition and greater financial resources that they can devote to product development or promotion.

Often power purchased from the electric utility grid can be less costly than power produced by distributed generation technologies. Utilities may also charge fees to interconnect to their power grids. However, we can provide economic benefits to end users in instances where the waste heat from our microturbine has value (CHP and CCHP), where fuel costs are low (renewable energy/renewable fuels), where the costs of connecting to the grid may be high or impractical (such as remote power applications), where reliability and power quality are of critical importance, or in situations where peak shaving could be economically advantageous because of highly variable electricity prices. Because our microturbines can provide a reliable source of power and can operate on multiple fuel sources, management believes we offer a level of flexibility not currently offered by other technologies such as reciprocating engines.

Our reciprocating engine competitors have products and markets that are well developed and technologies that have been proven for some time. A reciprocating engine, also known as an internal combustion engine, is similar to those used in automotive applications. Reciprocating engines are popular for primary and back-up power applications despite higher levels of emissions, noise, and maintenance. These technologies, which in many cases have a lower up front cost than microturbines, are currently produced by Caterpillar Inc., Cummins Inc. (which recently entered into a joint venture with Eaton), Innio (who recently bought the General Electric gas engine business, which now includes Waukesha and Jenbacher gas engines), MAN SE, and Tecogen, Inc. (which now includes American DG Energy Inc.), among others.

Our products may also compete with other distributed generation technologies, including solar-powered systems, wind-powered systems, fuel cells and fly wheel. Solar and wind powered systems produce no emissions and benefit from above market contracts provided by state mandates. The main drawbacks to solar and wind powered systems are that they may not be dispatchable because of their dependence on weather conditions, the utility grid or high capital costs that can often make these systems uneconomical without government subsidies depending upon geographic locale and application of the technology. Although the market is still developing, a number of fuel cell providers are also focused on markets similar to ours, including Active Power Inc. (a division of Piller Power Systems Inc.), Ballard Power Systems Inc., Bloom Energy Corporation, FuelCell Energy Inc., LG Fuel Cell Systems, a business unit of LG Electronics, and Plug Power Inc. Fuel cells have slightly lower levels of NOx, CO, VOCs and other criteria pollutant emissions than our microturbines. However, with equivalent government incentives, microturbines would provide a better economic value to end users in most applications.

We also compete with other companies that offer microturbine products, including FlexEnergy and Turbec S.p.A.

Overall, we compete with end users’ other options for electrical power and heat generation on the basis of our product’s ability to:

Governmental and Regulatory Impact

Our markets can be positively or negatively impacted by the effects of governmental and regulatory matters. We have systems installed in 73 countries around the world, each of which has its own policies and regulatory framework, which are subject to change. We are affected not only by energy policy, laws, regulations and incentives of governments in the markets in which we sell, but also by rules, regulations and costs imposed by utilities. Utility companies or governmental entities may place barriers on the installation or interconnection of our product with the electric grid. Further, utility companies may charge additional fees to customers that install on-site power generation; thereby reducing the electricity they take from the utility, or for having the capacity to use power from the grid for back-up or standby purposes. These types of restrictions, fees or charges could hamper the ability to install or effectively use our product, or increase the cost to our potential customers for using our systems. This could make our systems less economical for our customers, thereby adversely affecting our sales and ultimately our revenue and profitability. In addition, utility rate reductions can make our products less competitive which would have a material adverse effect on our operations. These costs, incentives and rules are not always the same as those faced by technologies with which we compete. However, rules, regulations, laws and incentives could also provide an advantage to our distributed generation solutions as compared with competing technologies if we are able to achieve required compliance in a lower cost, more efficient manner. Additionally, reduced emissions and higher fuel efficiency could help our customers combat the effects of climate change. Accordingly, we may benefit from increased government regulations that impose tighter emission standards particularly on burning coal and fuel oil and fuel efficiency as long as gas combustion technology solutions are not excluded.

Government funding can impact the rate of development of new technologies or improvements to existing technologies. We continue to engage with federal and state policymakers to support government programs that promote the deployment of our low emission and energy efficient products. Competing new technologies have historically received larger incentives and development funding than do microturbines. However, the U.S. Department of Energy continues to fund the development of cost-effective, high efficiency CHP that is responsive to site demands and grid requirements. Flexible CHP could provide additional generating capacity when grid demand increases or renewable resources are not available. As more intermittent renewable resources are added to the electric grid, grid operators need access to additional dispatchable generation capacity to ensure an adequate and stable power supply. Capstone’s PowerSync controller could provide this automated response capability to allow for participation in grid services markets, where permitted. Our addition of battery energy storage products to our portfolio of solutions opens our customers’ access to some of the higher incentives available to these technologies as well as allowing us to provide an integrated microturbine solution.

In the United States, a 10% Federal Investment Tax Credit (“ITC”) for CHP and microturbines was extended and is now available through the end of 2023. In addition, bonus depreciation rules allow businesses to immediately deduct 100% of eligible property placed in service after September 27, 2017 and before January 1, 2023. The deduction percentage will phase down from 100% to 0% by 2027. As a result, we may see a positive impact on our sales in the United States

13

Table of Contents

due to the availability of these tax incentives. However, other CHP and gas-powered distributed energy technology-providers will also benefit from the return of these tax incentives, and, fuel cell technologies will receive a 26% ITC level with a phase down to 22% by 2023 and expiration in 2024. At the state level, slow approvals for natural gas pipeline infrastructure may impact gas availability in some areas, and efforts to incentivize building electrification over natural gas-fueled heat and power sources may inhibit sales. However, electricity demand spikes may also lead to higher electricity prices thereby improving project economics for on-site distributed power generation.

In global markets, European governments continue to support efficient CHP and are beginning to act on reducing local air pollution through regulations like the EU’s Medium Combustion Plant and EcoDesign Directives. Our low emission systems’ ability to meet these programs’ requirements may have a positive impact on our sales as implementation progresses. However, the EU’s push for decarbonization may also leave natural gas-fueled, highly efficient systems in limbo despite their near-term carbon reduction potential and long term viability with the uptake of renewable and decarbonized gas alternatives. In the oil and gas market, many producers have committed to reduce methane emissions from their operations. Our low maintenance, reliable systems, and our ability to run on a range of fuels could fit their needs and result in a positive impact on our sales.

Sourcing and Manufacturing

We are focused on improving our supply chain effectiveness, strengthening our manufacturing processes, and increasing operational efficiencies within our organization. Our manufacturing designs include the use of conventional technology, which has been proven in high volume automotive and turbocharger production for many years. Many components used in the manufacture of our products are readily fabricated from commonly available raw materials or off the shelf items available from multiple supply sources; however, certain items are custom made to meet our specifications that require longer lead time. We believe that in most cases, adequate capacity exists at our suppliers and that alternative sources of supply are available or could be developed within a reasonable period. However, single source suppliers with long lead times may be more challenging to transition to another supplier. We have an ongoing program to develop alternative back up suppliers for sole source parts wherever possible, however this has been challenging with low production volumes and increased pricing. We regularly reassess the adequacy and abilities of our suppliers to meet our future needs. We continue to evaluate and implement new systems designed to provide improved quality, reliability, service, greater efficiency, and lower supply chain costs.

During Fiscal 2021, we remained focused on mitigating supply chain issues, such as the costs of commodities and delayed lead times, related to the ongoing global COVID-19 pandemic. Localization of the vast majority our immediate supply chain within a 300-mile radius of our factory located in Van Nuys, California mitigates much of the global stressors associated with a typical geographically dispersed supply chain, as many of our suppliers were sharing similar experiences of the pandemic in the same magnitude we were experiencing in parallel. Our prior years’ strategy of locating dual-sources and establishing long-term purchasing agreements helped to mitigate interruptions in our supply chain. Global freight delays, tariffs and costs remain a concern from a logistics perspective, however with a highly-localized supply chain, much of these effects are limited. To address delays, we increased planning fence lead-times within our ERP system to drive material purchases earlier, and we attempt to source products locally as much as possible. As with Fiscal 2020, the COVID-19 situation still remains fluid, and we are keeping in place proactive measures in the form of safety stocks and dual sourcing to prevent potential interruptions to our supply chain.  

We have substantially increased our focus on process controls and validations, supplier controls, distribution controls and providing our operations teams with the training and tools necessary to drive continuous improvement in product quality. In addition, we remain focused on examining our operations and general business activities to identify cost improvement opportunities to enhance our operational effectiveness and use lean manufacturing processes. Our ability to leverage these capabilities may be affected by the current variability in our demand volumes and forecasting. Our demand volumes and forecasting could continue to be negatively impacted by the volatility of the global oil and gas markets, a strong U.S. dollar (making our products more expensive overseas), tariffs and/or import taxes, and ongoing global geopolitical tensions. Our strategy is to identify primary and secondary sources for critical components, both domestic and international, for when available to minimize production line down time due to unavailability of such parts, which could affect our ability to meet manufacturing schedules on build or a linear basis. In April 2019, we executed multiple new Long Term Agreements (“LTA”), including a new 10-year LTA with a new supplier. The LTA from the new

14

supplier will initially reduce annual direct material costs by an estimated $2 million per year once the transition is completed. The strategy to reduce direct material costs is based on partnering with our supply base to drive collaborative cost improvements within its value chain, which will enable significant material cost reductions.

In 2007, we entered into a Development and License Agreement (“Development Agreement”) with Carrier Corporation (“Carrier”) regarding the payment of royalties on the sale of each of our C200 microturbines. On July 25, 2018, we and Carrier entered a Second Amendment whereby we concluded our royalty obligation under the Development Agreement and were released from any future royalty payment obligations. The Second Amendment also removed non-compete provisions from the Development Agreement, allowing us to design, market or sell our C200 System in conjunction with any energy system and compete with Carrier products in the CCHP market. There is no further royalty obligation to Carrier.

We have an approximately 42,300 square foot manufacturing footprint in our Van Nuys location in Southern California with production capacity of approximately 2,000 units per year, depending on product mix. We believe we will be able to support this production capacity level by adding additional shifts, which would increase working capital requirements, and making some additional capital expenditures when necessary.

Research and Development (“R&D”)

Our engineering mission flexed in Fiscal 2021 to supporting business operational goals and enhancing system availability to ensure continuity during the global pandemic.  While these successful efforts became our primary objectives, we continued to emphasize the expansion of our existing suite of products, focusing on alternative fuels and technologies, maintaining relevance in the global evolution of grid interconnection requirements, and the evolution of the PowerSync Controller. We focus our engineering efforts on coordinating our product design and manufacturing processes to bring our products to market in a cost-effective and timely manner. For Fiscal 2021 and 2020, R&D expenses were $2.4 million and $3.6 million, respectively, representing 4% and 5% of total revenue, respectively, for these fiscal years.

We own two patents related to fuel injection and emissions. The first patent issued is for a multi-staged lean pre-vaporizing, pre-mixing fuel injector providing ultra-low emissions that meet EPA Tier 4 requirements for power generation. Under this new program, exhaust emissions from these engines will be required to decrease by more than 90%. The second patent is for a multiple-fuel capable, pre-mixed, low emission injector for high flame speed fuel combustion.  This patent is the foundation for continued development in achieving high reliability and performance with hydrogen content fuels.

We partnered with the United States Department of Energy (“DOE”), which provided funding during Fiscal 2017 in the amount of $335,000 for one year to Argonne National Laboratory to conduct testing on a 70% hydrogen-30% natural gas configuration. Hydrogen testing was on hold while the test facility implemented mechanisms for safe handling, detection, and delivery of the hydrogen gas. The safety challenges have been resolved, and testing has begun. Funding has been extended to the 2021 government fiscal year for completion of the testing.

Capstone and Argonne National Laboratory are also partnering on a microturbine derivative utilizing Argonne’s high-efficiency, fast-charging, and fast discharging Thermal Energy Storage System.  This effort is funded through the Department of Energy’s Technology Commercialization Fund. The thermal storage system is expected to improve the microturbine’s overall efficiency increasing value to the customer. The Thermal Energy Storage System modeling and simulation was completed towards the end of Fiscal 2020.  During Fiscal 2021 design was completed on the assembly of the small scale system to be installed at Argonne using their C65 test system. We expect, Fiscal 2022 will see the procurement and assembly of the hardware at Argonne, and testing to validate the models that were developed.

We continue support of University of California, Irvine (“UCI”) through their Advanced Power and Energy Program, which works to evaluate microturbine operation using hydrogen and natural gas fuel blends.  The testing completed in Fiscal 2021 is sponsored by the local gas authority as they evaluate the impacts of gas grid hydrogen injection.  We and UCI continue to be key partners in advancing academic research while furthering commercialization of hydrogen technology in Fiscal 2022.

Table of Contents

Leveraging off this partnership, UCI has completed the first phase of analysis in associated gas combustion in catalog Capstone products.  Associated gas is represented by higher hydrocarbons, which are more challenging to maintain in gaseous state.  As more pressure is placed on flaring at oil and gas locations, the expansion of our fuel acceptability limits enables customers a reliable, resilient, and environmentally conscientious way of handling waste gases. Work continues in Fiscal 2022 to model and validate the combustion characteristics of associated gas, and update associated product documentation.

Our product development activities during Fiscal 2021 continued with the evolution of the new family of PowerSync controllers used for Capstone microturbines. We also further advanced a project to modernize control electronics, providing common functionality, minimizing near term obsolescence concerns, and enabling long term support. Leveraging our academic relationships, Capstone completed an initial analysis on the effective limits of our patented combustion system relative to higher hydrocarbon fuels.

We partnered with Phoenix Contact in a joint effort to improve on-site controls and integration with end-use customer facilities. The main objectives of developing the new PowerSync controller line were to further increase system reliability, availability and make our microturbines easier to use for both end-user customers as well as our distribution partners. Capstone and Phoenix Contact have been using customer feedback to make further improvements to software and hardware.

Grid interconnection standards have continued to evolve, with more emphasis being placed on harmonization of requirements.  AS-4777 certification for the C65 was able to be completed in Fiscal 2021. The remaining TUV Rheinland witness test efforts planned during Fiscal 2021 were postponed due to the COVID-19 pandemic.  Capstone used the remainder of the year for development work on the multiple updated certification requirements including German (BDEW, now VDE-4110) and Italian (CEI 0-16) medium voltage operation, German low voltage VDE-4105 operation, and California Rule 21 (soon to be incorporated into UL 1741 Supplement B).  This work will enable consolidation of the efforts during Fiscal 2022 witness tests.

Capstone and Argonne National Laboratory are also partnering on a microturbine derivative utilizing Argonne’s high-efficiency, fast-charging, and fast discharging Thermal Energy Storage System.  This effort is funded through the Department of Energy’s Technology Commercialization Fund. The thermal storage system is expected to improve the microturbine’s overall efficiency increasing value to the customer. The Thermal Energy Storage System modeling and simulation was completed towards the end of Fiscal 2020.  During Fiscal 2021 design was completed on the assembly of the small scale system to be installed at Argonne using their C65 test system.  Fiscal 2022 will see the procurement and assembly of the hardware at Argonne, and testing to validate the models that were developed.

In addition, we continue to work both cost reduction and performance enhancement activities to improve the value of our microturbine products for our customer base. Cost reduction activities are focused on leveraging the capabilities of our supply base and internal design lean manufacturing improvements. Product enhancements are focused on reducing the already very low maintenance requirements for our products, while at the same time improving operational efficiency, thereby reducing our customers’ total cost of ownership.

Because of our single moving assembly, manufacturers believe there is also the opportunity to produce a lower cost product in larger automotive volumes. Our focus is on a next generation product that would include existing components and a liquid cooled set of electronics that are consistent with the size, cost and cooling strategies employed on vehicles today. Although we believe the hybrid electric bus and truck market has the potential to be a beneficial option for the bus and truck manufacturers, we temporarily suspended our development efforts with respect to C30 microturbines targeted at this market in response to our lower revenue.

Our liquid fuel microturbines have demonstrated emissions levels which meet the CARB 2010 standards for Heavy Duty Diesel Engines (“HDDE”). The liquid fuel microturbine is able to meet these extremely low emissions requirements using its lean premix combustion technology with no exhaust aftertreatment. Competitive reciprocating engine technologies require aftertreatment components that increase system cost, require frequent maintenance, and impact engine efficiency. Our compressed natural gas (“CNG”) fueled microturbines also meet extremely strict emission standards, including the U.S. Environmental Protection Agency and CARB 2010 emissions requirements for On Road

16

Table of Contents

HDDE for Urban Bus. Test emissions from our natural gas microturbines measured dramatically less than the emissions levels set forth by the CARB standard including NOx at 75% and CO at 96% less than the required levels.

Our marine products have been used to provide hybrid electric marine propulsion, “hotel power,” CHP, or CCHP. They may be ideal for small and mid-size commercial ships that travel inland waterways and emissions controlled areas (“ECAs”). In partnership with one of our long-term EMEA distributors, Capstone developed a marine C65 for a private yacht manufacturer and in Fiscal 2020 we delivered the product and also received certification from Lloyd’s Register EMEA for Lloyd’s Register Rules and Regulations for the Classification of Special Service Craft 2018 - Part 6.  In Fiscal 2021, the private yacht power system was land tested, sea trialed, and launched, enabling the owner to eliminate onboard ship vibrations associated with reciprocating engines, while also having low emissions without after treatment.  Capstone received a follow-on certification from Lloyd’s for Classification of Special Service Craft 2018, Part 10, Chapter 2.

Our C65 Hybrid UPS product line has been evolving over the years. After having received the 2011 NOVA Award from the Construction Innovation Forum for the C65 Hybrid UPS Microturbine at Syracuse University’s data center—labeled one of the greenest data centers in the world, we have continued development of our C65 Hybrid UPS system and have installations at Sempra in Monterey Park, California and our own data center in Van Nuys, California as well as two Department of Homeland Security installations, among several others. The product utilizes our inverter electronics and controls technology to provide continuous power quality to meet the customer’s critical load. The load inverter is connected through a central power bus to provide power from one of three available power sources, including the utility grid, battery storage system, or microturbine generator. Power to the critical load is synchronized to an available utility grid to allow direct bypass of the critical load to the utility grid. This redundant functionality is provided in a single integrated package that can be scaled to a larger seamless power unit through our multipack feature. These units can also be combined with a heat recovery module or an absorption chiller to provide higher total output efficiency. Unlike current UPS products combined with reciprocating engines for backup, our low emissions Hybrid UPS product allows for continuous operation year-round, allowing customers the ability to receive a payback on their capital equipment investment. Although we believe the industrial UPS market has the potential to be a beneficial option for businesses that require constant supply of reliable energy, we temporarily suspended our development efforts with respect to C65 microturbines targeted at this market in response to our lower revenue. We currently intend to continue with the next phase of development after we achieve profitability.

Protecting our Intellectual Property Rights and Patents

We rely on a combination of patent, trade secret, copyright, “know how”, and trademark laws and nondisclosure agreements to establish and protect our intellectual property rights in our products. We have 37 U.S. and 3 international active patents (in certain cases covering the same technology in multiple jurisdictions). The patents we have obtained will expire between the second half of calendar years 2021 and 2037. We actively evaluate our patent portfolio and pursue new patent applications as we develop new technological innovations, as needed.

We believe that a policy of protecting intellectual property is one component of our strategy of being the leader in microturbine system technology and will provide us with a long term competitive advantage. In addition, we implement security procedures at our plants and facilities and have confidentiality agreements with our suppliers, distributors, employees and certain visitors to our facilities.

Human Capital

On February 16, 2021, our board of directors adopted an amended charter governing our Compensation and Human Capital Committee, after discussing the rapid movement to expand the role of the Compensation Committee beyond traditional compensation-related matters. In accordance with its recently amended charter, our Compensation and Human Capital Committee is responsible for reviewing, monitoring and providing recommendations to our board of directors on our workplace policies and practices, including corporate culture and employee engagement, talent management and leadership development, employee diversity and inclusion, ensuring a respectful workplace free of discrimination and harassment.

Risks Related to Our Business Operations and Financial Results

The ongoing effects of the COVID-19 pandemic could adversely affect our business, financial condition, results of operations, or cash flows.

An infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV-2) that was first detected in November 2019 in the city of Wuhan, China, known as COVID-19, resulted in an outbreak throughout the world. The subsequent spread of COVID-19 to the U.S. and many other parts of the world led the World Health Organization to characterize COVID-19 as a pandemic on March 11, 2020. Thereafter, most U.S. states imposed “stay-at-home” orders on their populations to stem the spread of COVID-19. Of specific interest to the Company, stay-at-home orders were imposed in the state of California on March 20, 2020. Governments, public institutions, and other organizations in countries and localities throughout the world have taken and are continuing to take certain emergency measures to combat the spread of COVID-19, including implementation of restrictions on travel and orders that restrict the operations of institutions such as schools and businesses. These conditions have negatively impacted all aspects of our business. Our business is also dependent on the continued health and productivity of our employees, including our manufacturing employees, sales staff, and corporate management teams.

In addition, due to domestic and international governmental orders restricting certain activities in response to COVID-19, including in Van Nuys, California, where our corporate headquarters and many of our operations, including our principal manufacturing facility, are located, we have experienced, and may in the future experience, certain disruptions in our business, including changes to our on-site operations to reduce manufacturing capacity and implement social distancing, reductions in our suppliers’ ability to source, maintain inventory and ship raw materials in alignment with our demands, work stoppages, slowdowns and delays, including having most of our employees working outside of our offices, travel restrictions, reduced access to our customers for product training and case support, and cancellation of events, delays in product development efforts, and other negative impacts on our capacity to manufacture, our suppliers’ capacity to source and ship raw materials and our distributors’ ability to sell and support the use of our products.

The COVID-19 pandemic has also caused significant uncertainty and volatility in global financial markets. Due to such volatility, we may not be able to raise additional capital, if needed, on favorable terms, or at all. Further adverse economic events resulting from the COVID-19 pandemic, including sustained economic downturn, could materially and adversely affect our business, access to capital markets and the value of our common stock.

Additionally, our liquidity could be negatively impacted if these conditions continue for a significant period of time and we may be required to pursue additional sources of financing to obtain working capital, maintain appropriate inventory levels, and meet our financial obligations.

Despite the introduction of Covid-19 vaccines, the pandemic remains highly volatile and continues to evolve. The ultimate impact of the COVID-19 pandemic is highly uncertain and subject to change. We do not yet know the full extent of potential impacts on our business, healthcare systems, the medical device industry or the global economy as a whole. However, these effects could adversely impact our business, financial condition, results of operations, or cash flows.

Our operating history is characterized by net losses. We anticipate further losses and we may never become profitable.

Since inception, we have incurred annual operating losses. We expect this trend to continue until such time that we can sell a sufficient number of units and achieve a cost structure to become profitable. Our business is such that we have relatively few repeat end use customers and limited repeat business compared to our competitors. As a result, we may not maintain or increase revenue. We may not have adequate cash resources to reach the point of profitability, and we may never become profitable. Even if we do achieve profitability, we may be unable to increase our sales and sustain or increase our profitability in the future.

We may be unable to fund our future operating requirements, which could force us to curtail our operations.

To the extent that the funds we now have on hand are insufficient to fund our future operating requirements, we would need to raise additional funds, through further public or private equity or debt financings depending upon prevailing market conditions. These financings may not be available or, if available, may be on terms that are not favorable to us and could result in dilution to our stockholders and reduction of the trading price of our stock. The state of capital markets when we seek to raise additional capital could also impede our ability to raise additional capital on favorable terms or at all. If adequate capital were not available to us, we likely would be required to significantly curtail our operations or possibly even cease our operations.

We are party to an Amended and Restated Note Purchase Agreement (the “A&R Note Purchase Agreement”) dated October 1, 2020 (the “Closing Date”) among the Company, certain subsidiaries of the Company, Goldman Sachs Specialty Lending Group, L.P. (as successor in interest to Goldman Sachs Specialty Lending Holdings, Inc.), as collateral agent (“Goldman” or the “Collateral Agent”) and the purchasers party thereto (the “Purchasers”). The A&R Note Purchase Agreement amended and restated our Note Purchase Agreement dated February 4, 2019, by and among the Company, certain subsidiaries of the Company, Goldman Sachs Specialty Lending Holdings, Inc. and the purchasers party thereto under which we sold $30.0 million aggregate principal amount of senior secured notes (the “Notes”) bearing an interest of 13.0% per annum. Pursuant to the A&R Note Purchase Agreement, the Company issued $20.0 million in additional Notes and all outstanding Notes under the A&R Note Purchase Agreement bear interest at the Adjusted (London Interbank Offer) LIBO Rate (as defined in the A&R Note Purchase Agreement) plus 8.75% per annum, payable on the last day of each interest period of one-, two-, three- or six-months (but, in the case of a six-month interest period, every three-months). The Notes do not amortize and the entire principal balance is due and payable on October 1, 2023. As of March 31, 2021, $51.0 million in borrowings were outstanding under the Notes, which includes the accrual for an exit fee to be paid at maturity or upon pre-payment. Obligations under the A&R Note Purchase Agreement are secured by all of the Company’s assets, including intellectual property and general intangibles. The A&R Note Purchase Agreement contains customary covenants, including, among others, covenants that restrict our ability to incur debt, grant liens, make certain investments and acquisitions, pay dividends, repurchase equity interests, repay certain debt, amend certain contracts, enter into affiliate transactions and asset sales or make certain equity issuances (including equity issuances that would cause an ownership change within the meaning of Section 382 of the Internal Revenue Code), and covenants that require us to, among other things, provide annual, quarterly and monthly financial statements, together with related compliance certificates, maintain our property in good repair, maintain insurance and comply with applicable laws.  

On May 13, 2021, the Company, and the collateral agent, entered into a First Amendment, dated as of May 13, 2021 (the “Amendment”), to the A&R Note Purchase Agreement.  The Amendment amended certain provisions of the A&R Note Purchase Agreement, including to (a) require the Company to expand its Rental Fleet (as defined in the A&R Note Purchase Agreement) by (i) at least 2.00 MW by the 9-month anniversary of the Closing Date (instead of 6.25 MW as provided in the A&R Note Purchase Agreement prior to the Amendment), and (ii) at least 12.50 MW by the 18-month anniversary of the Closing Date (which is unchanged from the covenant set forth in in the A&R Note Purchase Agreement prior to the Amendment), and (b) increase the Company’s minimum consolidated liquidity requirement from $9,000,000 to $12,200,000 for the period from May 13, 2021 to March 31, 2022.

The A&R Note Purchase Agreement also defines an event of default as, among other things, payment default, bankruptcy events, cross defaults, breaches of covenants and representations and warranties, changes of control, judgment defaults and an ownership change within the meaning of Section 382 of the Internal Revenue Code. An event of default, if not waived, could have a material adverse effect on us.

Our obligations under the A&R Note Purchase Agreement could have important consequences, including the following:

22

Table of Contents

We may be required to repay the Notes immediately if we default on any of the numerous financial or other restrictive covenants contained in the A&R Note Purchase Agreement. It is not certain whether we will have, or will be able to obtain, sufficient funds to make any such accelerated payments. If any outstanding indebtedness under the Notes is accelerated, our assets may not be sufficient to repay such indebtedness.

If we are unable to either substantially improve our operating results or obtain additional financing, we may be unable to continue to operate at current levels.

We have experienced recurring operating losses and as of March 31, 2021, we had an accumulated deficit of approximately $919.3 million. On March 31, 2021, we had cash and cash equivalents of $49.5 million, and working capital of $52.5 million. This compares to $900.9 million, $15.1 million and $29.8 million, respectively, on March 31, 2020. As a condition of the A&R Note Purchase Agreement with the Purchasers, our consolidated liquidity (defined as the aggregate amount of unrestricted cash and cash equivalents included in the consolidated balance of the Company and our subsidiaries, subject to certain conditions as defined in the A&R Note Purchase Agreement) on any date may not be less than $12.2 million for the period from the Amendment Date to March 31, 2022.

Our business strategy is focused on profitability-oriented initiatives such as reducing operating expenses, increasing sales of products and services, thereby diversifying, and increasing revenue, and improving gross margin. We may not be able to execute the business strategy successfully and if we are unable to generate positive cash flow, potential customers may choose not to purchase our products or utilize our program. Moreover, the business strategy is based upon projections, which are in turn based upon estimates and assumptions. There can be no assurance as to the accuracy of the projections, estimates and assumptions which underlie the business strategy or as to our ability to execute the business strategy successfully.

Should we be unable to execute our plans to increase sales and margins while controlling costs, we may be unable to continue to operate at our current levels on a longer-term basis. In particular, we must generate positive cash flow from operations and net income and otherwise improve our results of operations substantially on a longer-term basis. Our available cash and proceeds from future financings, if any, that we may be able to obtain, may not be sufficient to fund our operating expenses, capital expenditures and other cash requirements. Any such lack of funds would affect our ability to continue to operate at current levels. These events and circumstances could have a material adverse effect on our ability to raise additional capital and on the market value of our common stock and our ability to maintain Notes financing. Moreover, should we experience a cash shortage that requires us to curtail or cease our operations, which could materially adversely affect the market price of our common stock.

A sustainable market for microturbines may never develop or may take longer to develop than we anticipate which would adversely affect our results of operations.

Our products represent an emerging market, and we do not know whether our targeted customers will accept our technology or will purchase our products in sufficient quantities to allow our business to grow. To succeed, demand for our products must increase significantly in existing markets, and there must be strong demand for products that we introduce in the future. In addition, as part of our business strategy, we are focusing our marketing efforts on the energy

23

Table of Contents

efficiency, renewable energy, natural resources, critical power, microgrid and transportation markets. We may be unable to grow our business in these target markets. If a sustainable market fails to develop or develops more slowly than we anticipate, we may be unable to recover the losses we have incurred to develop our products, we may have further impairment of assets, and we may be unable to meet our operational expenses. The development of a sustainable market for our systems may be hindered by many factors, including some that are out of our control. Examples include:

Product quality expectations may not be met, causing slower market acceptance or warranty cost exposure.

In order to achieve our goal of improving the quality and lowering the total costs of ownership of our products, we may require engineering changes. Such improvement initiatives may render existing inventories obsolete or excessive. Despite our continuous quality improvement initiatives, we may not meet customer expectations. Any significant quality issues with our products could have a material adverse effect on our rate of product adoption, results of operations, financial condition, and cash flow. Moreover, as we develop new configurations for our microturbines and as our customers place existing configurations in commercial use, our products may perform below expectations. Any significant performance below expectations could adversely affect our operating results, financial condition and cash flow and affect the marketability of our products.

We sell our products with warranties. There can be no assurance that the provision for estimated product warranty will be sufficient to cover our warranty expenses in the future. We cannot ensure that our efforts to reduce our risk through warranty disclaimers will effectively limit our liability. Any significant incurrence of warranty expense in excess of estimates could have a material adverse effect on our operating results, financial condition and cash flow. Further, we have at times undertaken programs to enhance the performance of units previously sold. For example, during Fiscal 2017, we recorded a non-cash warranty provision of approximately $5.2 million to proactively retrofit select non-Signature Series C200 microturbines with the more robust new Signature Series generator components to improve product performance and reliability. Additionally, our warranty provision was negatively impacted in Fiscal 2019 and Fiscal 2021 because of a supplier defect identified in fielded units. In Fiscal 2021 a warranty reserve in the amount of $4.9 million was established related to reliability programs to account for the replacement of remaining high risk failure parts in some of our fielded units due to a supplier defect. These enhancements have at times been provided at no cost or below our cost. If we choose to offer such programs again in the future, such actions could result in significant costs.

On February 22, 2021 we announced that we had reached a financial settlement in the amount of $5 million arising out of claims pursued in confidential arbitration with such former strategic parts supplier. We obtained this settlement following a multi-year arbitration process.  Any future product quality issues with our parts suppliers could lead

24

Table of Contents

to lengthy and costly litigation, even if the outcome is ultimately in our favor. In addition, such quality issues with any of our parts could lead to us to fail to meet the product quality expectations of our own customers, which could adversely affect our operating results, financial condition and cash flow and affect the marketability of our products.

Our products involve a lengthy sales cycle, and we may not anticipate sales levels appropriately, which could impair our results of operations.

The sale of our products typically involves a significant commitment of capital by customers, which can result in the typical delays associated with large capital expenditures. For these and other reasons, the sales cycle associated with our products is typically lengthy and subject to several significant risks over which we have little or no control. We plan our production and inventory levels based on internal forecasts of customer demand, which is highly unpredictable and can fluctuate substantially. If sales in any period fall significantly below anticipated levels, our financial condition, results of operations and cash flow would suffer. If demand in any period increases well above anticipated levels, we may have difficulties in responding, incur greater costs to respond, or be unable to fulfill the demand in sufficient time to retain the order, which would negatively impact our operations. In addition, our operating expenses are based on anticipated sales levels, and a high percentage of our expenses are generally fixed in the short term. As a result of these factors, a small fluctuation in timing of sales can cause operating results to vary materially from period to period.

Net product orders for Fiscal 2021 were $25.9 million and contributed to an ending backlog of $29.4 million at March 31, 2021. The book-to-bill ratio was 1.1:1 for Fiscal 2021. Book-to-bill ratio is the ratio of new orders we received to units shipped and billed during a period. However, because our backlog represents only the estimated amount of future product revenue to be recognized under negotiated contracts as shipments convert backlog to recognized revenue for accounting purposes, we may not be able to fully realize the revenue value reported in our backlog, and our backlog may not be indicative of future revenues. A portion of our backlog is concentrated in the international oil and gas market which may impact the overall timing of shipments or the conversion of backlog to revenue. The timing of the backlog is based on the requirement date indicated by our customers. Based on historical experience, management expects that a significant portion of our backlog may not be shipped within the next 18 months. The timing of shipments is subject to change based on several variables (including customer deposits, payments, availability of credit and customer delivery schedule changes), most of which are not in our control and can affect the timing of our revenue. As a result, management believes the book-to-bill ratio better demonstrates the current demand for our products in the given period.

If we do not effectively implement our sales, marketing and service plans, our sales will not grow and our results of operations will suffer.

Our sales and marketing efforts may not achieve intended results and, therefore, may not generate the revenue we anticipate. As a result of our corporate strategies, we have decided to focus our resources on selected vertical markets. We may change our focus to other markets or applications in the future. There can be no assurance that our focus or our near term plans will be successful. If we are not able to address markets for our products successfully, we may not be able to grow our business, compete effectively or achieve profitability.

Changes to trade regulation, quotas, duties or tariffs, and sanctions caused by the changing U.S. and geopolitical environments or otherwise, may increase our costs or limit the amount of raw materials and products that we can import, or may otherwise adversely impact our business.

The former U.S. administration has voiced strong concerns about imports from countries that it perceives as engaging in unfair trade practices. Any current or future U.S. administration may decide to impose import duties or other restrictions on products, components or raw materials sourced from those countries, which may include China, Mexico, and other countries from which we import components or raw materials. Any such duties or restrictions could have a material adverse effect on our business, results of operations or financial condition.

Moreover, any new tariffs, or other changes in U.S. trade policy, could trigger retaliatory actions by affected countries. Certain foreign governments have instituted or are considering imposing trade sanctions on certain U.S. goods. Others are considering the imposition of sanctions that will deny U.S. companies access to critical raw materials. A “trade war” of this nature or other governmental action related to tariffs or international trade agreements or policies has the

25

Table of Contents

potential to adversely impact demand for our products, our costs, customers, suppliers and/or the U.S. economy or certain sectors thereof and, thus, to adversely impact our businesses.

The U.S. government imposes sanctions through executive orders restricting U.S. companies from conducting business activities with specified individuals and companies, such as in Russia and the Ukraine, and requires export licenses for certain of such activities. While we believe that the executive orders currently do not have a material impact on our business, the sanctions imposed by the U.S. government could be expanded in the future. If we are unable to conduct business with new or existing customers or pursue opportunities with sanctioned countries, our business, including revenue, profitability, and cash flows, could be materially adversely affected.

We may not be able to retain or develop relationships with OEMs or distributors in our targeted markets, in which case our sales would not increase as expected.

In order to serve certain of our targeted markets, we believe that we must ally ourselves with companies that have particular expertise or better access to those markets. We believe that retaining or developing relationships with strong OEMs (which to date have typically resold our products under their own brands or packaged our products with other products as part of an integrated unit) or distributors in these targeted markets can improve the rate of adoption as well as reduce the direct financial burden of introducing a new technology and creating a new market. Because of OEMs’ and distributors’ relationships in their respective markets, the loss of an OEM or distributor could adversely impact the ability to penetrate our target markets. We offer our OEMs and distributors stated discounts from list price for the products they purchase. In the future, to attract and retain OEMs and distributors we may provide volume price discounts or otherwise incur significant costs that may reduce the potential revenue from these relationships. We may not be able to retain or develop appropriate OEMs and distributors on a timely basis, and we cannot provide assurance that the OEMs and distributors will focus adequate resources on selling our products or will be successful in selling them. In addition, some of the relationships may require that we grant exclusive distribution rights in defined territories. These exclusive distribution arrangements could result in our being unable to enter into other arrangements at a time when the OEM or distributor with whom we form a relationship is not successful in selling our products or has reduced its commitment to market our products. We cannot provide assurance that we will be able to negotiate collaborative relationships on favorable terms or at all. Our inability to have appropriate distribution in our target markets may adversely affect our financial condition, results of operations and cash flow.

If any of our distributor relationships is not successful, we may terminate or choose not to renew the related distributor agreement, which may result in interference with the wind down of the relationship or the transition of end-user service agreements, and could potentially negatively impact our distribution channel or result in litigation costs or other expenses.

Successfully managing our distribution channel in an effort to reach various potential customer segments for our products and services is a complex process. Each of our distributors is a strategically placed independent partner that provides for marketing and selling of our products and services on our behalf. If our distribution relationships are not successful, we may lose sales opportunities, customers, and revenues. Our agreements with our distribution partners require them to comply with performance conditions that are subject to interpretation, which could result in disagreements. At any given time, we may be in disputes with one or more distribution partners. Any such dispute could result in lengthy and costly litigation, even if the outcome is ultimately in our favor. We cannot predict the outcome of any arbitration or litigation, the effect of any negative judgment against us or the amount of any settlement that we may enter into with such distribution partners. A contractual dispute with a distribution partner may result in our or our distribution partner seeking to terminate the related distribution agreement, even if such termination would be wrongful, which could harm our business, or interfere with a previously agreed wind down of the relationship or transition of end-user service agreements. Any prolonged disruptions of our distribution channels that results from the termination of one or more of our distributions or our failure to renew our distribution agreements with our desired distributors, could negatively affect our ability to effectively sell our products and would materially and adversely affect our business, financial condition, results of operations and prospects.

We have substantial accounts receivable, and increased bad debt expense or delays in collecting accounts receivable could have a material adverse effect on our cash flows and results of operations.

Our accounts receivable balance, net of allowances, was $20.6 million and $16.2 million as of March 31, 2021 and 2020, respectively. Days sales outstanding in accounts receivable (“DSO”) at the end of Fiscal 2021 was 111 days, compared with 85 days at the end of Fiscal 2020. We recorded net bad debt recovery of approximately $0.2 million during Fiscal 2021, and net bad debt expense of approximately $0.4 million during Fiscal 2020. No assurances can be given that future bad debt expense will not increase above current operating levels. Increased bad debt expense or delays in collecting accounts receivable could have a material adverse effect on results of operations and cash flows.

Loss of a significant customer could have a material adverse effect on our results of operations.

CAL and E-Finity accounted for approximately 15% and 12%, respectively, of our revenue for Fiscal 2021. Additionally, E-Finity accounted for 13% of net accounts receivable as of March 31, 2021. The loss of CAL, E-Finity or any other significant customer could have a material adverse effect on our results of operations and financial condition.

We may not achieve production cost reductions necessary to competitively price our products, which would adversely affect our sales.

We believe that we will need to reduce the unit production cost of our products over time to maintain our ability to offer competitively priced products. Our ability to achieve cost reductions will depend on our ability to develop low cost design enhancements, to obtain necessary tooling and favorable supplier contracts and to increase sales volumes so we can achieve economies of scale. We cannot provide assurance that we will be able to achieve any such production cost reductions. Our failure to achieve such cost reductions could have a material adverse effect on our business and results of operations.

We have realized reductions in our operating costs and, as a result, our ability to cut costs further and sustain our business initiatives may be limited.

Since April 2015, we have implemented various initiatives to reduce operating costs across all functions of the Company and focus our business efforts on our most promising near-term product opportunities. As a result of these cost-cutting initiatives, which we have already undertaken over an extended period of time, we may have a more limited ability to further reduce costs to increase our liquidity should such measures become necessary. Any further reductions may have a materially negative impact on our business.

We may incur costs and liabilities as a result of product liability claims.

We face a risk of exposure to product liability claims in the event that the use of our products is alleged to have resulted in injury or other damage. Although we currently maintain product liability insurance coverage, we may not be able to obtain such insurance on acceptable terms in the future, if at all, or obtain insurance that will provide adequate coverage against potential claims. Product liability claims can be expensive to defend and can divert the attention of management and other personnel for long periods of time, regardless of the ultimate outcome. A significant unsuccessful product liability defense could have a material adverse effect on our financial condition and results of operations. In addition, we believe our business depends on the strong brand reputation we have developed. If our reputation is damaged, we may face difficulty in maintaining our market share and pricing with respect to some of our products, which could reduce our sales and profitability.

Operational restructuring may result in asset impairment or other unanticipated charges.

As a result of our corporate strategy, we have identified opportunities to outsource to third-party suppliers certain functions which we currently perform. We believe outsourcing can reduce product costs, improve product quality and increase operating efficiency. These actions may not yield the expected results, and outsourcing may result in production delays or lower quality products. Transitioning to outsourcing may cause certain of our affected employees to leave before the outsourcing is complete. This could result in a lack of the experienced in-house talent necessary to successfully

27

Table of Contents

implement the outsourcing. Further, depending on the nature of operations outsourced and the structure of agreements we reach with suppliers to perform these functions, we may experience impairment in the value of manufacturing assets related to the outsourced functions or other unanticipated charges, which could have a material adverse effect on our operating results.

We may not be able to manage our growth effectively, expand our production capabilities or improve our operational, financial and management information systems, which would impair our results of operations.

If we are successful in executing our business plan, we will experience growth in our business that could place a significant strain on our business operations, management and other resources. Our ability to manage our growth will require us to expand our production capabilities, continue to improve our operational, financial and management information systems, and to motivate and effectively manage our employees. We cannot provide assurance that our systems, procedures and controls or financial resources will be adequate, or that our management will keep pace with this growth. We cannot provide assurance that our management will be able to manage this growth effectively.

Our success depends in significant part upon the continuing service of management and key employees.

Our success depends in significant part upon the continuing service of our executive officers, senior management and sales and technical personnel. The failure of our personnel to execute our strategy or our failure to retain management and personnel could have a material adverse effect on our business.

Our success, growth prospects, and ability to capitalize on market opportunities also depend to a significant extent on our ability to identify, hire, motivate and retain qualified managerial personnel, including senior members of management. There can be no assurances that we can do so. Our growth may be constrained by resource limitations as competitors and customers compete for increasingly scarce human capital resources. The demand for skilled workers is currently high. Our competitors may be able to offer a work environment with higher compensation or more opportunities than we can. If we are unable to attract and retain a sufficient number of skilled personnel, our ability to successfully implement our business plan, grow our Company and maintain or expand our product offerings may be adversely affected, and the costs of doing so may increase, which may adversely impact our business, financial condition and results of operations.

In addition, our internal control systems rely on employees trained in the execution of the controls. Loss of these employees or our inability to replace them with similarly skilled and trained individuals or new processes in a timely manner could adversely impact our internal control mechanisms.

Our operations are vulnerable to interruption by fire, earthquake and other events beyond our control.

Our operations are vulnerable to interruption by fire, earthquake, and other events beyond our control. Our executive offices, manufacturing facility, and auxiliary inventory storage facility are located in southern California. Because the southern California area is located in an earthquake-sensitive area and because we have no redundancy facility located within or outside of southern California, we are particularly susceptible to the risk of damage to, or total destruction of, our facilities in southern California and the surrounding transportation infrastructure, which could affect our ability to make and transport our products. If an earthquake, fire, or other natural disaster occurs at or near our facilities, our business, financial condition, operating results and cash flow could be materially adversely affected.

Activities necessary to integrate any future acquisitions may result in costs in excess of current expectations or be less successful than anticipated.

We may acquire other businesses in the future and the success of these transactions will depend on, among other things, our ability to develop productive relationships with the corresponding distributors and to integrate assets and personnel, if any, acquired in these transactions and to apply our internal controls processes to these acquired businesses. Future acquisitions may require us to raise financing including by issuing common stock that would dilute our current stockholders’ percentage ownership, assume or otherwise be subject to liabilities of an acquired company, record goodwill and non-amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic

28

Table of Contents

impairment charges, incur amortization expenses related to certain intangible assets, incur large acquisition and integration costs, immediate write-offs, and restructuring and other related expenses, and become subject to litigation. The benefits of an acquisition may also take considerable time to develop, and we cannot be certain that any particular acquisition will produce the intended benefits in a timely manner or to the extent anticipated or at all. We may experience difficulties integrating the operations, technologies, products, and personnel of an acquired company or be subjected to liability for the target’s pre-acquisition activities or operations as a successor in interest. Such integration may divert management’s attention from normal daily operations of our business. Future acquisitions may also expose us to potential risks, including risks associated with entering markets in which we have no or limited prior experience, especially when competitors in such markets have stronger market positions, the possibility of insufficient revenues to offset the expenses we incur in connection with an acquisition and potential loss of, or harm to, our relationships with employees, customers, consumers and suppliers as a result of integration of new businesses. If we are unable to fully benefit from anticipated synergies, our business, financial condition, results of operations, and cash flows could be materially adversely affected.

Risks Related to Our Product Offerings

​

We depend upon the development of new products and enhancements of existing products

Our operating results depend on our ability to develop and introduce new products, enhance existing products and reduce the costs to produce our products. The success of our products is dependent on several factors, including proper product definition, product cost, timely completion and introduction of the products, differentiation of products from those of our competitors, meeting changing customer requirements, emerging industry standards and market acceptance of these products. The development of new, technologically advanced products and enhancements is a complex and uncertain process requiring high levels of innovation, as well as the accurate anticipation of technological and market trends. There can be no assurance that we will successfully identify new product opportunities, develop and bring new or enhanced products to market in a timely manner, successfully lower costs and achieve market acceptance of our products, or that products and technologies developed by others will not render our products or technologies obsolete or uncompetitive. We continued to expand and develop our new hydrogen products during Fiscal 2021, which are commercially available running on a 10% hydrogen – 90% natural gas mix. Continued development towards a 100% hydrogen product will require a long time horizon and a significant amount of financial resources. There can be no assurance that we will have the resources or financial ability to develop a 100% hydrogen product.

Our operating results are dependent, in large part, upon the successful commercialization of our products. Failure to produce our products as scheduled and budgeted would materially and adversely affect our business and financial condition.

We cannot be certain that we will deliver ordered products in a timely manner. We have limited production slots for our products. Any delays in production will increase our costs, reduce future production slots and could significantly impact our business, financial condition and operating results.

We may not be able to produce our products on a timely basis if we fail to correctly anticipate product supply requirements or if we suffer delays in production resulting from issues with our suppliers. Our suppliers may not supply us with a sufficient amount of components or components of adequate quality, or they may provide components at significantly increased prices.

Some of our components are currently available only from a single source or limited sources. We may experience delays in production if we fail to identify alternative suppliers, or if any parts supply is interrupted, each of which could materially adversely affect our business and operations. In order to reduce manufacturing lead times and ensure adequate component supply, we enter into agreements with certain suppliers that allow them to procure inventories based upon criteria defined by us. If we fail to anticipate customer demand properly, an oversupply of parts could result in excess or obsolete inventories, which could adversely affect our business. Additionally, if we fail to correctly anticipate our internal supply requirements, an undersupply of parts could limit our production capacity. Our inability to meet volume commitments with suppliers could affect the availability or pricing of our parts and components. A reduction or interruption in supply, a significant increase in price of one or more components or a decrease in demand of products could materially adversely affect our business and operations and could materially damage our customer relationships. Financial problems of suppliers on whom we rely could limit our supply of components or increase our costs. Also, we cannot

29

Table of Contents

guarantee that any of the parts or components that we purchase will be of adequate quality or that the prices we pay for the parts or components will not increase. Inadequate quality of products from suppliers could interrupt our ability to supply quality products to our customers in a timely manner. Additionally, defects in materials or products supplied by our suppliers that are not identified before our products are placed in service by our customers could result in higher warranty costs and damage to our reputation. We also outsource certain of our components internationally. As a result of outsourcing internationally, we may be subject to delays in delivery because of regulations associated with the import/export process, delays in transportation or regional instability.

Commodity market factors impact our costs and availability of materials.

Our products contain a number of commodity materials from metals, which include steel, special high temperature alloys, copper, nickel and molybdenum, to computer components. The availability of these commodities could impact our ability to acquire the materials necessary to meet our production requirements. The cost of metals has historically fluctuated. The pricing could impact the costs to manufacture our products. If we are not able to acquire commodity materials at prices and on terms satisfactory to us or at all, our operating results may be materially adversely affected.

We operate in a highly competitive market among competitors that have significantly greater resources than we have and we may not be able to compete effectively.

We compete with several technologies, including reciprocating engines, fuel cells and solar power. Competing technologies may receive certain benefits, like governmental subsidies or promotion, or be able to offer consumer rebates or other incentives that we cannot receive or offer to the same extent. This could enhance our competitors’ abilities to fund research, penetrate markets or increase sales. We also compete with other manufacturers of microturbines.

Our competitors include several well-known companies with histories of providing power solutions. They have substantially greater resources than we do and have established worldwide presence. Because of greater resources, some of our competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements, to devote greater resources to the promotion and sale of their products than we can or lobby for governmental regulations and policies to create competitive advantages vis-à-vis our products. We believe that developing and maintaining a competitive advantage will require continued investment by us in product development and quality, as well as attention to product performance, our product prices, our conformance to industry standards, manufacturing capability and sales and marketing. In addition, current and potential competitors have established or may in the future establish collaborative relationships among themselves or with third parties, including third parties with whom we have business relationships. Accordingly, new competitors or alliances may emerge and rapidly acquire significant market share.

Overall, the market for our products is highly competitive and is changing rapidly. We believe that the primary competitive factors affecting the market for our products, including some that are outside of our control, include:

There is no assurance that we will be able to successfully compete against either current or potential competitors or that competition will not have a material adverse effect on our business, operating results, financial condition and cash flow.

Our business and financial performance depends in part on the oil and natural gas industry, where a continued movement towards clean energy and away from fossil fuels, as well as a decline in prices for oil and natural gas may have an adverse effect on our revenue, cash flows, profitability and growth.

We experienced a decrease in revenue in Fiscal 2021 and Fiscal 2020 due to declining oil prices, as well as a movement towards clean energy and away from fossil fuels, which has impacted capital expenditures in the oil and natural gas industry. We continue to be impacted by the volatility of the global oil and gas industry. If prices were to remain low or decline further, we would expect to see additional declines in our customers' spending which would have an adverse effect on our revenue. In addition, a worsening of these conditions may result in a material adverse impact on certain of our customers' liquidity and financial position resulting in further spending reductions, delays in the collection of amounts owing to us and other similar adverse effects.

Our sales and results of operations could be materially and adversely impacted by risks inherent in international markets.

As we expand in international markets, customers may have difficulty or be unable to integrate our products into their existing systems or may have difficulty complying with foreign regulatory and commercial requirements. As a result, our products may require redesign. Any redesign of the product may delay sales or cause quality issues. In addition, we may be subject to a variety of other risks associated with international business, including import/export restrictions, fluctuations in currency exchange rates and economic or political instability. Our business in particular is also subject to risks relating to uncertainties and effects of the implementation of the United Kingdom’s referendum to withdraw membership from the EU (referred to as “Brexit”), including financial, legal, tax and trade implications. In addition, doing business internationally subjects us to risks relating to political or social unrest, as well as corruption and government regulation, including laws such as the Foreign Corrupt Practices Act and the U.K. Bribery Act, that impose stringent requirements on how we conduct our foreign operations.

We may not be able to develop sufficiently trained applications engineering, installation and service support to serve our targeted markets.

Our ability to identify and develop business relationships with companies that can provide quality, cost-effective application engineering, installation and service can significantly affect our success. The application engineering and proper installation of our microturbines, as well as proper maintenance and service, are critical to the performance of the units. Additionally, we need to reduce the total installed cost of our microturbines to enhance market opportunities. Our inability to improve the quality of applications, installation and service while reducing associated costs could affect the marketability of our products.

Changes in our product components may require us to replace parts held at distributors.

We have entered into agreements with some of our distributors requiring that if we render parts obsolete in inventories they own and hold in support of their obligations to serve fielded microturbines, we are required to replace the affected stock at no cost to the distributors. As a result, it is possible that future changes in our product technology could involve costs that have a material adverse effect on our results of operations, cash flow or financial position.

Utility companies or governmental entities could place barriers to our entry into the marketplace, and we may not be able to effectively sell our products.

Utility companies or governmental entities could place barriers on the installation of our products or the interconnection of the products with the electric grid. Further, they may charge additional fees to customers who install on-site generation or have the capacity to use power from the grid for back-up or standby purposes. These types of restrictions, fees or charges could hamper the ability to install or effectively use our products or increase the cost to our potential customers for using our systems. This could make our systems less desirable, thereby adversely affecting our revenue and other operating results. In addition, utility rate reductions can make our products less competitive which would have a material adverse effect on our operations. The cost of electric power generation bears a close relationship to natural gas and other fuels. However, changes to electric utility tariffs often require lengthy regulatory approval and include a mix of fuel types as well as customer categories. Potential customers may perceive the resulting swings in natural gas and electric pricing as an increased risk of investing in on-site generation.

Risks Related to Pending Litigation and Government Regulation

​

We operate in a highly regulated business environment, and changes in regulation could impose significant costs on us or make our products less economical, thereby affecting demand for our microturbines.

Our products are subject to federal, state, local and foreign laws and regulations, governing, among other things, emissions and occupational health and safety. Regulatory agencies may impose special requirements for the implementation and operation of our products or that may significantly affect or even eliminate some of our target markets. We may incur material costs or liabilities in complying with government regulations. In addition, potentially significant expenditures could be required in order to comply with evolving environmental and health and safety laws, regulations, requirements and approvals that may be adopted or imposed in the future. We can provide no assurances that we will be able to obtain any such approvals in a timely manner, or at all. Non-compliance with applicable regulations could have a material adverse effect on our operating results.  Furthermore, our potential utility customers must comply with numerous laws and regulations. The deregulation of the utility industry may also create challenges for our marketing efforts. For example, as part of electric utility deregulation, federal, state and local governmental authorities may impose transitional charges or exit fees, which would make it less economical for some potential customers to switch to our products.

The market for electricity and generation products is heavily influenced by federal and state government regulations and policies. The deregulation and restructuring of the electric industry in the United States and elsewhere may cause rule changes that may reduce or eliminate some of the advantages of such deregulation and restructuring. We cannot determine how any deregulation or restructuring of the electric utility industry may ultimately affect the market for our microturbines. Changes in regulatory standards or policies could reduce the level of investment in the research and development of alternative power sources, including microturbines. Any reduction or termination of such programs could increase the cost to our potential customers, making our systems less desirable, and thereby adversely affect our revenue and other operating results.

We have significant tax assets, usage of which may be subject to limitations in the future.

At March 31, 2021, we had federal and state net operating loss carryforwards of approximately $592.7 million and $163.0 million, respectively, which may be utilized to reduce future taxable income, subject to limitations under Section 382 of the Internal Revenue Code of 1986. These deferred tax assets have been fully offset by a valuation allowance. Any subsequent accumulations of common stock ownership leading to a change of control under Section 382 of the U.S. Internal Revenue Code of 1986, including through sales of stock by large stockholders, which are outside of our control, could limit and defer our ability to utilize our net operating loss carryforwards to offset future federal income tax liabilities.

We are subject to a number of pending lawsuits.

We and certain of our current and former officers are named as defendants in a shareholder class action lawsuit filed in the United States District Court for the Central District of California, and in a separate but similar lawsuit brought by two individual shareholders in the United States District Court for the Central District of California. Additionally, we and certain of our current and former officers and directors are named as defendants in various state and federal derivative suits. We may be named as defendants in future lawsuits. These current and future matters may result in significant liabilities and diversion of our management’s time, attention and resources. Given the uncertain nature of litigation generally, we are not able in all cases to estimate the amount or range of loss that could result from an unfavorable outcome in these matters. In view of these uncertainties, the outcome of these matters may result in charges in excess of any established reserves and, to the extent available, liability insurance. Protracted litigation, including any adverse outcomes, may have an adverse impact on our business, financial condition or results of operations. In addition, any significant judgment or settlement amount may require us to incur additional indebtedness, adversely affect our liquidity and ability to service our indebtedness, or require us to restructure or amend the terms of our indebtedness. See Item 3—Legal Proceedings of this Form 10-K for more information regarding currently pending legal proceedings.

Table of Contents

In addition, from time to time, we may face litigation relating to intellectual property, labor, product liability, stockholder and other matters. An adverse judgment could negatively impact our financial position and results of operations, the trading price of our common stock and our ability to obtain future financing on favorable terms or at all. Whether or not resolved in a manner adverse to us, any litigation could be costly, divert management attention or result in increased costs of doing business. Further, our insurance coverage is limited for these and other claims against us, and we may not have adequate insurance or financial resources to pay for our liabilities or losses from any such claims

Risks Related to Data, Security, and Intellectual Property

Our business could be negatively impacted if we fail to adequately protect our intellectual property rights or if third parties claim that we are in violation of their intellectual property rights.

We view our intellectual property rights as important assets. We seek to protect our intellectual property rights through a combination of patent, trademark, copyright and trade secret laws, as well as licensing and confidentiality agreements. These protections may not be adequate to prevent third parties from using our intellectual property without our authorization, breaching any confidentiality agreements with us, copying or reverse engineering our products, or developing and marketing products that are substantially equivalent to or superior to our own. The unauthorized use of our intellectual property by others could reduce our competitive advantage and harm our business. If it became necessary for us to litigate to protect these rights, any proceedings could be burdensome and costly and we may not prevail. We cannot guarantee that any patents, issued or pending, will provide us with any competitive advantage or will not be challenged by third parties. Moreover, the expiration of our patents may lead to increased competition with respect to certain products. In addition, we cannot be certain that we do not or will not infringe third parties’ intellectual property rights. Any such claim, even if it is without merit, may be expensive and time-consuming to defend, subject us to damages, cause us to cease making, using or selling certain products that incorporate the disputed intellectual property, require us to redesign our products, divert management time and attention and/or require us to enter into costly royalty or licensing arrangements.

We face security and cybersecurity risks related to our electronic processing of sensitive and confidential business and product data. If we are unable to protect our data or the data of our customers, a security breach could damage our reputation and have a material adverse effect on our business.

As a manufacturer of high technology commercial products, we face security and cyber security threats, as well as the potential for business disruptions associated with information technology failures or cyber security attacks. Given the nature of our business, we collect process and retain sensitive and confidential customer and associate data, in addition to proprietary business information. Our business, including our turbines and related energy assets may be vulnerable to a data compromise, computer viruses, physical and electronic break-ins and manipulations and similar disruptions, which may not be prevented by our efforts to secure our computer systems and assets, which include vulnerability scans and patching, network firewalls, identity and access management, data encryption, intrusion detection and prevention devices. Our cybersecurity efforts may not be able to prevent rapidly evolving types of cyber-attacks and a successful breach of our computer systems could result in misappropriation of personal, payment or sensitive business information. In addition, we rely on associates, contractors and other third parties that may attempt to circumvent our security measures in order to obtain such information and may purposefully or inadvertently cause a breach involving such information. A security breach involving confidential and proprietary data or the fleet of turbines we have deployed across the globe for our customers could damage our reputation and our ability to retain existing customers or gain new customers and impact the competitive advantages derived from our R&D efforts, the usefulness of our products and services, and ultimately our stock price.  In addition, we may incur material liabilities and remediation costs as a result of a security breach and, our insurance may not be sufficient to cover the impact to the business.  Moreover, evolving privacy laws in the United States, Europe and elsewhere, including the adoption by the European Union of the General Data Protection Regulation (“GDPR”), which became effective May 2018, establishes new individual privacy rights and imposes increased obligations on companies handling personal data. Consequently, we may incur significant costs related to prevention and compliance with laws regarding the protection and unauthorized disclosure of personal information. A failure to comply with the stringent rules of the GDPR could result in fines of up to €20 million. Further, a greater number of our employees are working remotely in response to the COVID-19 pandemic and related government actions, which could expose us to greater risks related to cybersecurity and our information technologies systems.

Risks Related to Ownership of Our Common Stock

​

We cannot be certain of the future effectiveness of our internal controls over financial reporting. If we are unable to maintain effective internal controls over our financial reporting, investors may lose confidence in our ability to provide reliable and timely financial reports and the value of our common stock may decline.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we are required to include in our annual reports on Form 10-K our assessment of the effectiveness of our internal controls over financial reporting. This assessment includes disclosure of any material weaknesses identified by our management in our internal controls over financial reporting. Our management concluded that our internal controls over financial reporting were effective as of March 31, 2021. We may in the future identify material weaknesses in our internal controls over financial reporting that could result in a material misstatement of our financial statements. Our internal control over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. If we cannot adequately maintain the effectiveness of our internal controls over financial reporting, we may not be able to produce timely and accurate financial statements. If that were to happen, our investors could lose confidence in our reported financial information, the market price of our common stock could decline and we might be subject to sanctions or investigation by regulatory authorities, such as the SEC.

Future issuances or sales of our common stock or exercises by holders of our outstanding warrants could lower our stock price and dilute the interests of existing stockholders.

We may issue additional shares of our common stock in the future. The issuance of a substantial amount of common stock could have the effect of substantially diluting the interests of our current stockholders. In addition, the sale of a substantial amount of common stock in the public market, either in the initial issuance or in a subsequent resale by investors that acquired such common stock, could have a material adverse effect on the market price of our common stock. We may sell up to $50.0 million of shares of our common stock in “at-the-market’ offerings pursuant to the sales agreement entered into with H.C. Wainwright & Co., LLC on June 7, 2018 and as amended on July 15, 2020 and March 29, 2021. The sale of a substantial number of shares of our common stock pursuant to the sales agreement, or anticipation of such sales, could cause the trading price of our common stock to decline or make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise desire. In addition, issuances of any shares of our common stock sold pursuant to the sales agreement will have a dilutive effect on our existing stockholders.

We cannot predict the effect, if any, that future public sales of our common stock or the availability of additional shares of our common stock for sale will have on the market and trading price of our common stock. In addition, we currently have warrants outstanding for the purchase of up to an aggregate of 1.1 million shares of our common stock and certain of our warrant holders also have the right to require us to register under the Securities Act the shares issuable upon exercise of their warrants. In addition, some of our outstanding warrants contain anti-dilution provisions that may, under certain circumstances, increase the number of shares issuable thereunder. To the extent the warrants outstanding are fully exercised, a significant number of shares of common stock will be issued, which will result in dilution to the holders of our shares of common stock and an increase in the number of shares eligible for resale in the public market. If any of our stockholders sell substantial amounts of our common stock in the public market, or if the public perceives that such sales could occur, this could have an adverse impact on the market and trading price of our securities, even if there is no relationship between such sales and the performance of our business.

The market price of our common stock has been, and may continue to be, highly volatile and you could lose all or part of your investment in our securities.

An investment in our securities is risky, and stockholders could lose their investment in our securities or suffer significant losses and wide fluctuations in the market value of their investment. The market price of our common stock is highly volatile and is likely to continue to be highly volatile. Given the continued uncertainty surrounding many variables that may affect our business and the industry in which we operate, our ability to foresee results for future periods is limited. This variability could affect our operating results and thereby adversely affect our stock price. Many factors that contribute

34

Table of Contents

to this volatility are beyond our control and may cause the market price of our common stock to change, regardless of our operating performance. Factors that could cause fluctuation in our stock price may include, among other things:

Market conditions may result in volatility in the level of, and fluctuations in, market prices of stocks generally and, in turn, our common stock and sales of substantial amounts of our common stock in the market, in each case being unrelated or disproportionate to changes in our operating performance. Concerns over global stability and economic conditions in the United States and abroad have contributed to the extreme volatility of the markets which may influence the market price of our common stock. In the past, following periods of volatility in the market price of a company’s

35

Table of Contents

securities, securities class action litigation has often been instituted against the company. This type of litigation, regardless of whether we prevail on the underlying claim, could result in substantial costs and a diversion of management’s attention and resources, which could materially harm our financial condition, results of operations and cash flow.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable independent research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If one or more of the analysts that covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

Provisions in our certificate of incorporation, bylaws and our NOL rights plan, as well as Delaware law, may discourage, delay or prevent a merger or acquisition at a premium price.

Provisions of our second amended and restated certificate of incorporation, amended and restated bylaws and our stockholder rights plan, as well as provisions of the General Corporation Law of the State of Delaware, could discourage, delay or prevent unsolicited proposals to merge with or acquire us, even though such proposals may be at a premium price or otherwise beneficial to you. These provisions include our board’s authorization to issue shares of preferred stock, on terms the board determines in its discretion, without stockholder approval, and the following provisions of Delaware law that restrict many business combinations.

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware, which could prevent us from engaging in a business combination with a 15% or greater stockholder for a period of three years from the date such stockholder acquired such status unless appropriate board or stockholder approvals are obtained.

On May 6, 2019, we and Broadridge Financial Solutions, Inc. successor-in-interest to Computershare Inc., as Rights Agent, entered into a Rights Agreement (the “NOL Rights Agreement”) designed to diminish the risk that our ability to use our net operating losses and certain other tax assets to reduce potential future federal income tax obligations would become subject to limitations by reason of us experiencing an “ownership change,” as defined in Section 382 of the Internal Revenue Code of 1986, as amended. The NOL Rights Agreement replaces the Company’s Rights Agreement, dated May 6, 2016, by and between the Company and Broadridge Financial Solutions, Inc., as successor-in-interest to Computershare Inc., as rights agent (the “Original Rights Agreement”). While this NOL Rights Agreement is intended to preserve our net operating losses, it effectively deters current and future purchasers from becoming 4.99% stockholders. The NOL Rights Agreement could also make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders.

We do not intend to pay cash dividends. We have never paid dividends on our capital stock and we do not anticipate paying any dividends in the foreseeable future. Consequently, any gains from an investment in our securities will likely depend on whether the price of our common stock increases.

We have not paid dividends on any of our capital stock to date and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future. Consequently, in the foreseeable future, you will likely only experience a gain from your investment in our securities if the price of our common stock increases.

General Risk Factors

​

Adverse economic conditions may have an impact on our business and financial condition, including some effects we may not be able to predict.

Adverse economic conditions may prevent our customers from purchasing our products or delay their purchases, which would adversely affect our business, financial condition and results of operations. In addition, our ability to access the capital markets may be severely restricted or made very expensive at a time when we need, or would like, to do so,

36

Table of Contents

which could have a material adverse impact on our liquidity and financial resources. Certain industries in which our customers do business and certain geographic areas have been and could continue to be adversely affected by adverse economic conditions. Our revenue continues to be negatively impacted by the volatility of the global oil and gas markets, a strong U.S. dollar (making our products more expensive overseas) and ongoing global geopolitical tensions.

Our business may be impacted by international instability, war, terrorism, and geopolitical events.

International political and economic instability or volatility, geopolitical regional conflicts, terrorist activity, political unrest, civil strife, acts of war, public corruption, expropriation and other economic or political uncertainties could interrupt and negatively affect the performance of our services, sale of our products or other business operations. A slowdown in economic growth in some emerging markets could result in long sales cycles, greater risk of uncollectible accounts and longer collection cycles. Fluctuations or devaluations in currency values, especially in emerging markets, could have an adverse effect on us, our suppliers, logistics providers and manufacturing vendors. All of these factors could result in increased costs or decreased revenues, and could materially and adversely affect our product sales, financial condition and results of operations.

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

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from the results discussed in the forward-looking statements. Factors that might cause a difference include, but are not limited to, those discussed under “Note Regarding Forward-Looking Statements” and Item 1A (Risk Factors) in this Form 10-K. The following section is qualified in its entirety by the more detailed information, including our financial statements and the notes thereto, which appears elsewhere in this Form 10-K.

Overview

We are the market leader in microturbines based on the number of microturbines sold. Generally, power purchased from the electric utility grid is less costly than power produced by distributed generation technologies. Utilities may also charge fees to interconnect to their power grids. However, we can provide economic benefits to end users in instances where the waste heat from our microturbine has value (CHP) and (CCHP), where fuel costs are low (renewable energy/renewable fuels), where the costs of connecting to the grid may be high or impractical (such as remote power applications), where reliability and power quality are of critical importance, or in situations where peak shaving could be economically advantageous because of highly variable electricity prices. Our microturbines can be interconnected to other distributed energy resources to form “microgrids” (also called “distribution networks”) located within a specific geographic area and provide power to a group of buildings. Because our microturbines can provide a reliable source of power and can operate on multiple fuel sources, management believes they offer a level of flexibility not currently offered by other technologies such as reciprocating engines. In addition to our existing microturbine products, we offer additional energy conversion products in the form of Baker Hughes 5 MW, 12 MW, and 16 MW industrial gas turbines, where we will purchase and resell their product. The Company is currently exploring energy conversion options for the smaller end of the power spectrum. We will begin to manufacture modular hybrid energy stations and lithium-ion BESS to be sold either individually or combined as part of a custom microturbine-battery storage solution. We added a new Energy Storage Products business line in Fiscal 2022 and thus there has been no revenue to date.

Our goals for Fiscal 2021 were to improve cash flow, working capital, and our balance sheet generally; grow revenue through accelerating global product sales; diversify into additional market verticals and geographies; increase aftermarket sales absorption; and continue to grow our rental fleet. During Fiscal 2021 our net loss was $18.4 million and our basic and diluted net loss per share was $1.63, compared to $22.0 million and $2.70, respectively, in the same period of the previous fiscal year. Our net loss improved during Fiscal 2021 primarily because of lower overhead and operating expenses incurred as a result of implementing our COVID-19 Business Continuity Plan, as well as lower FPP costs as our reliability improved due to the reduced impact of the part defect from a supplier first identified during the first quarter of Fiscal 2019, partially offset by lower overall gross margins from lower revenue levels and increased discounting driven by the COVID-19 pandemic and loss on extinguishment of debt of $4.3 million. On October 1, 2020, the Company entered into an Amended & Restated Note Purchase Agreement (the “A&R Note Purchase Agreement”), and issued $20.0 million in additional Notes. See Note 11—Term Note Payable, in the Notes to Consolidated Financial Statements for discussion with respect to this A&R Note Purchase Agreement.

On July 15, 2020, we entered into an amended Sales Agreement with H.C. Wainwright & Co., LLC with respect to an at-the-market offering program (the “ATM Program”) pursuant to which we may offer and sell, from time to time at our sole discretion, shares of our common stock. On March 19, 2021, we entered into a second amendment to the Sales Agreement, which modified the Sales Agreement to, among other things, reflect the Company’s filing of a new Registration Statement on Form S-3 with the SEC on March 22, 2021 and set the maximum number of shares of our Common Stock that we may offer and sell through or to H.C. Wainwright at $50,000,000, subject to certain limitations set forth in the amendment. See Note 9—Stockholders’ Equity, in the Notes to Consolidated Financial Statements for discussion with respect to the Sales Agreement.

Our products continue to gain interest in all our major vertical markets (energy efficiency, renewable energy, natural resources, critical power supply, microgrid and transportation). In the energy efficiency market, we continue to expand our market presence in hotels, office buildings, hospitals, retail, and industrial applications globally. The renewable energy market is fueled by landfill gas, biodiesel, and biogas from sources such as food processing, agricultural waste and

39

Table of Contents

livestock manure. Our product sales in the oil and gas and other natural resources market is driven by our microturbines’ reliability, emissions profile and ease of installation. Given the volatility of the oil and gas market, our business strategy is to target projects within the energy efficiency and renewable energy markets.

We continue to focus on improving our products based on customer input, building brand awareness and new channels to market by developing a diversified network of strategic distribution partners. Our focus is on products and solutions that provide near term opportunities to drive repeatable business rather than discrete projects for niche markets. In addition, management closely monitors operating expenses and strives to improve manufacturing efficiencies while simultaneously lowering direct material costs and increasing average selling prices. The key drivers to our success are revenue growth, higher average selling prices, lower direct material costs, positive new order flow and reduced cash usage.

An overview of our direction, targets and key initiatives follows:

Focus on Vertical Markets  Within the distributed generation markets that we serve, we focus on vertical markets that we identify as having the greatest near-term potential. In our primary products and applications (energy efficiency, renewable energy, natural resources, critical power supply, microgrid and transportation products), we identify specific targeted vertical market segments. Within each of these segments, we identify what we believe to be the critical factors to success and base our plans on those factors. Given the volatility of the oil and gas market, we have refocused our business strategy to target projects within the energy efficiency and renewable energy markets.

The following table summarizes our product shipments by vertical markets:

Energy Efficiency—CHP/CCHP

Energy efficiency refers to the proper utilization of both electrical and thermal energies in the power production process. In such applications, our microturbines are able to maximize the availability of usable energy to provide a significant economic advantage to customers while reducing their onsite emissions. CHP and CCHP can improve site economics by capturing the waste heat created from a single combustion process to increase the efficiency of the total system, from approximately 30 percent to 80 percent or more. Compared with more traditional, independent generation sources, the increase in operational efficiency also reduces greenhouse gas emissions through the displacement of other separate systems, which can also reduce operating costs.

Natural Resources—Crude Oil, Natural Gas, Shale Gas & Mining

Our microturbines are installed in the natural resource market for use in both onshore and offshore applications, including oil and gas exploration, production, and at compression and transmission sites as a highly efficient and reliable source of power. In some cases, these oil and gas or mining operations have no electric utility grid and rely solely on power generated onsite. There are numerous locations, on a global scale, where the drilling, production, compression and transportation of natural resources and

40

Table of Contents

other extraction and production processes create fuel byproducts, which are traditionally burned or released into the atmosphere. Our microturbines can turn these fuel byproducts - flare gas, or associated gas, into a useable fuel to provide prime power to these sites.

Renewable Energy

There is a growing transition to renewable energy sources and technologies on a global scale. Our microturbines run efficiently on renewable fuels such as methane and other biogases from landfills, wastewater treatment facilities and renewable natural gas. They also run efficiently on other small biogas applications like food processing plants, livestock farms and agricultural green waste operations. Microturbines can burn these renewable fuels with minimal emissions, thereby, and in some cases, avoiding the imposition of penalties incurred for pollution while simultaneously producing electricity from this “free” renewable fuel source for use at the site or in the surrounding areas. Our microturbines have demonstrated effectiveness in these smaller applications and may outperform conventional combustion engines in some situations, including when the gas contains a high amount of sulfur, as the sulfur can contaminate combustion engines lube oil leading to equipment breakdowns and higher lifecycle costs.

Critical Power Supply

Because of the potentially catastrophic consequences of system failure, momentary or otherwise, certain high demand power users, including high technology, health care and information systems facilities require higher levels of reliability in their power generation service. To meet these customer requirements, traditional solutions utilize Uninterruptible Power Supplies (“UPS”) to protect critical loads from power disturbances along with back-up diesel generators for extended outages. We offer an alternative solution that can both meet customer reliability requirements and reduce operating costs. We have seen continued development in the critical market segment as it relates to heath care facilities.

Microgrid

Microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable energy entity with respect to the grid. Distributed energy resources typically include other dual-mode microturbines, reciprocating engines, solar photovoltaic (PV), wind turbine, fuel cells and battery storage. Microgrids can be connected to larger electricity grids; however, in the event of a widespread outage, the microgrid will disconnect from the main grid and continue to operate independently to maintain the electricity supply to the homes and businesses that are connected to the microgrid’s electricity network. Our microturbines have the ability to meet the needs of microgrid end-users by lowering their overall cost to operate and by providing a versatile dispatchable technology that is fuel flexible and scalable enough to fit a wide variety of applications. We have seen continued development in the microgrid market segment.

Transportation

Our technology is also used in Hybrid Electric Vehicle (“HEV”) applications. Our customers have applied our products in HEV applications such as transit buses and Class 7 and 8 work trucks. In these applications, the microturbine acts as an onboard battery charger to recharge the battery system as needed. The benefits of microturbine-powered HEV hybrids include extended range, fuel economy gains, quieter operation, reduced emissions, and higher reliability when compared with traditional internal combustion engines.

Additionally, our technology is used in marine applications. Our customers have applied our products in the commercial vessel and luxury yacht market segments. The application for our marine products is for use as a ship auxiliary engine. In this application, the microturbines provide power to the vessel’s electrical loads and, in some cases, the vessel can utilize the exhaust energy to increase the overall efficiency of the application, thereby reducing overall fuel consumption and emissions. Another feasible

application is similar to our HEV application where the vessel is driven by an electric propulsion system and the microturbine serves as an on board range extender. Transportation is a developing market segment for us. In Fiscal 2020 and Fiscal 2021, transportation products were only for customer demonstrations. We have experienced continued development in these vertical markets and remain focused on the development of these applications.

Backlog

Net product orders were approximately $25.9 million and $33.8 million for Fiscal 2021 and Fiscal 2020, respectively. Ending backlog was approximately $29.4 million at March 31, 2021 compared to $37.7 million at March 31, 2020. Book-to-bill ratio was 1.1:1 and 1.4:1 for Fiscal 2021 and 2020, respectively. Book-to-bill ratio is the ratio of new orders we received to units shipped and billed during a period.

A portion of our backlog is concentrated in the oil and gas market which may impact the overall timing of shipments or the conversion of backlog to revenue. The timing of the backlog is based on the requirement date indicated by our customers. However, based on historical experience, management expects that a significant portion of our backlog may not be shipped within the next 18 months. Additionally, the timing of shipments is subject to change based on several variables (including customer deposits, payments, availability of credit and customer delivery schedule changes), most of which are not in our control and can affect the timing of our revenue. As a result, management believes the book-to-bill ratio demonstrates the current demand for our products in the given period.

Effective January 1, 2018, we launched our Distributor Support System (“DSS program”) to provide additional support for distributor business development activities, customer lead generation, brand awareness and tailored marketing services for each of our major geography and market verticals. This program is funded by our distributors and was developed to provide improved worldwide distributor training, sales efficiency, website development and company branding and provide funding for increased strategic marketing activities. See Note 2—Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements for additional discussion of revenue recognition for this program.

Our FPP backlog at the end of Fiscal 2021 and Fiscal 2020 was approximately $75.1 million and $82.4 million, respectively, which represents the value of the contractual agreement for FPP services that has not been earned and extends through Fiscal 2041. Additionally, we offer new and remanufactured parts through our global distribution network. Service revenue in Fiscal 2021 was approximately 32% of total revenue.

During Fiscal 2020, we introduced and expanded our PowerSync family of controllers, easily customizable for our microturbine systems. Additionally, we delivered our first production self-cleanable severe environment air filtration system for our Signature Series line of microturbine products.

We continue to modernize electronics to today’s standards, providing common functionality and enabling long term support. To support our global fleet during Fiscal 2020, we achieved Australian AS4777 certification for our C200 product line, and UK G99 Grid Interconnect type approval for our C65 and C200 product lines. In addition, Germany released VDE 4110 for Medium Voltage Grid Interconnection, to augment the BDEW certification. We achieved “Prototype Confirmation” for this new specification that enables continued operability in Germany.

In partnership with one of our long-term EMEA distributors, we developed a marine C65 for a private yacht manufacturer and in Fiscal 2020 we delivered the product and also received certification from Lloyd’s Register EMEA for Lloyd’s Register Rules and Regulations for the Classification of Special Service Craft 2018 - Part 6.

We are also developing a more efficient microturbine CHP system with the support of the DOE, which awarded us a grant of $5.0 million in support of this development program, of which $4.2 million was allocated to us and was used through September 30, 2015. We successfully completed the first phase of the development program on September 30, 2015 and achieved 270 kW with a prototype C250 microturbine in our development test lab. Management intends to continue with the next phase of development and commercialization after we achieve profitability. The next phase will be to continue development of the C250 product architecture, as well as the associated power electronics and software controls required for successful commercialization.

During Fiscal 2021, we continued to expand and develop our new hydrogen products. We released our first commercially available hydrogen-based combined heat and power (CHP) product, which can safely run on a 10% hydrogen-90% natural gas mix, and we are targeting a commercial release of a product that will run on a 30% hydrogen-70% natural gas mix product by March 31, 2022. In furtherance of those efforts, we are testing a 70% hydrogen-30% natural gas configuration through our research and development partnership with Argonne National Laboratory.

Our manufacturing designs include the use of conventional technology, which has been proven in high- volume automotive and turbocharger production for many years. Many components used in the manufacture of our products are readily fabricated from commonly available raw materials or off the shelf items available from multiple supply sources; however, certain items are custom made to meet our specifications that require longer lead time. We believe that in most cases, adequate capacity exists at our suppliers and that alternative sources of supply are available or could be developed within a reasonable period of time; however, single source suppliers with long lead times may be more challenging to transition to another supplier. We regularly reassess the adequacy and abilities of our suppliers to meet our future needs.

We believe that effective execution in each of these key areas will be necessary to leverage our promising technology and early market leadership into achieving positive cash flow with growing market presence and improving financial performance.

We currently occupy warehouse and office space in Van Nuys, California with a production capacity of approximately 2,000 units per year, depending on product mix. We believe we will be able to support this production capacity level by adding additional shifts, which would increase working capital requirements, and making some additional capital expenditures when necessary.

Reverse Stock Split  At the annual meeting of stockholders of the Company held on August 29, 2019, the Company’s stockholders approved an amendment to our Second Amended and Restated Certificate of Incorporation (the “Amendment”) to effect a reverse stock split of our common stock at a ratio in the range of one-for-five (1:5) to one-for-ten (1:10). Pursuant to such authority granted by the stockholders, the Company’s board of directors approved a one-for-ten (1:10) reverse stock split (the “Reverse Stock Split”) of the common stock and the filing of the Amendment. The Certificate of Amendment was filed with the Secretary of State of Delaware, effective on October 21, 2019 and the Reverse Stock Split became effective as of that date. Accordingly, all references to numbers of shares of common stock, including the number of shares of common stock on an as-if-converted basis, per-share data and share prices and exercise prices in the accompanying condensed consolidated financial statements have been adjusted to reflect the reverse stock split on a retroactive basis.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosures of contingent liabilities. On an on-going basis, we evaluate our estimates, including but not limited to those related to long-lived assets, including finite-lived intangible assets and fixed assets, bad debts, inventories, warranty obligations, stock-based compensation, income taxes and contingencies. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe that the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Certain reclassifications have been made to the prior year’s financial statements to enhance comparability with the current year’s financial statements. As a result, certain line items have been amended in the Consolidated Statements of Operations and the related notes to the consolidated financial statements. Comparative figures have been adjusted to conform to the current year’s presentation. The items were reclassified as follows (in thousands):

The following table summarizes our revenue by geographic markets (amounts in millions):

46

Table of Contents

Revenue for Fiscal 2021 decreased $1.3 million, or 2%, to $67.6 million from $68.9 million for Fiscal 2020. The change in revenue for Fiscal 2021 compared to Fiscal 2020 included decreases in revenue of $1.9 million from the Latin American markets and $1.4 million from the Middle East and African markets. These overall decreases in revenue were offset by increases in revenue of $0.7 million from the European and Russian markets, $0.7 million from the Asian and Australian markets, and $0.6 million from the United States and Canadian markets. The slight decrease in revenue in all geographic markets during Fiscal 2021 compared to the same period the previous year was primarily because of (i) lower parts revenue due to the COVID-19 pandemic, which affected the timing of customer demand for our products; (ii) as well as weakness in the oil and gas market as a result of a decline in oil prices and (iii) continued movement towards clean energy and away from fossil fuels, which impacted capital expenditures in the natural resources market during Fiscal 2021.

The following table summarizes our revenue (revenue amounts in millions):

For Fiscal 2021, revenue from microturbine products and accessories increased $1.2 million, or 3%, to $36.5 million from $35.3 million for Fiscal 2020. The increase in revenue was primarily because of an increase in product volume and a strengthening of the United States and Canadian markets compared to the same period last year. Megawatts shipped during Fiscal 2021 increased 0.3 megawatts, or 1%, to 33.5 megawatts from 33.2 megawatts during Fiscal 2020. Average revenue per megawatt shipped was approximately $1.0 million in both Fiscal 2021 and 2020. The timing of shipments is subject to change based on several variables (including customer deposits, payments, availability of credit and delivery schedule changes), most of which are not within our control and can affect the timing of our revenue.

Parts and service revenue for Fiscal 2021 decreased $2.5 million, or 7%, to $31.1 million from $33.6 million for Fiscal 2020. The decrease in revenue was primarily a result of lower parts revenue due to COVID-19 shutdowns and movement restrictions in all of our global markets, partially offset by higher service revenue due to increases in our Energy as a Service business line, which includes revenue from our FPP contracts and other service revenue.

Sales to CAL and E-Finity accounted for 15% and 12%, respectively, of our revenue for the fiscal year ended March 31, 2021. Sales to E-Finity accounted for 12% of our revenue for the year ended March 31, 2020.

Gross Margin  Cost of goods sold includes direct material costs, production and service center labor and overhead, inventory charges and provision for estimated product warranty expenses. Gross margin was approximately $6.9 million, or 10% of revenue, for Fiscal 2021, compared to gross margin of $9.1 million, or 13% of revenue, for Fiscal 2020. The decrease in gross margin of $2.2 million during Fiscal 2021 compared to Fiscal 2020 was primarily because of an incremental increase of $5.3 million in warranty expense, partially offset by a $1.0 million increase in our direct material costs margin, a decrease in production and service center labor and overhead expense of $1.7 million, and lower inventory charges of $0.4 million. Management continues to implement initiatives to improve gross margin in Fiscal 2022 by further reducing manufacturing overhead and direct material costs and improving product performance as we work to achieve profitability.

Direct material costs margin, calculated as total revenue less our direct material costs, increased $1.0 million during Fiscal 2021 compared to Fiscal 2020 primarily because of higher product margin due to higher volume.

The increase in warranty expense of $5.3 million during Fiscal 2021 compared to Fiscal 2020 was primarily due to the establishment of a reserve related to reliability programs to account for the replacement of remaining high risk failure parts in some of our fielded units due to a supplier defect.

47

Table of Contents

Production and service center labor and overhead expense decreased $1.7 million during Fiscal 2021 compared to Fiscal 2020 primarily because of decreases of approximately $1.1 million in labor costs from our COVID-19 Business Continuity Plan actions, $0.7 million in facilities costs, $0.3 million in consulting expense, $0.3 million in supplies expense and $0.1 million in import tax costs, partially offset by $0.8 million in overhead allocated to finished goods inventory.

Inventory charges decreased $0.4 million during Fiscal 2021 compared to Fiscal 2020 primarily as the result of a decrease in the provision for excess and obsolete inventory.

The following table summarizes our gross margin (in millions except percentages):

Product and accessories gross margin decreased $5.5 million during Fiscal 2021 compared to Fiscal 2020 primarily due to: (i) the establishment of a warranty reserve to replace high-risk parts in fielded units affected by sub-optimal parts initially provided by a former strategic parts supplier; (ii) a decrease in volume of product shipments from weakness in the oil and gas market due to a decline in oil price; (iii) the continued movement towards clean energy and away from fossil fuels, which impacted capital expenditures in the natural resources market during Fiscal 2021; and (iv) the COVID-19 pandemic, which has affected the timing of customer demand for our products compared to the same period last year. Parts and service gross margin improved $2.5 million during Fiscal 2021 compared to Fiscal 2020 primarily due to lower FPP costs as our reliability improves as we work through the part defect from a supplier first identified during the first quarter of Fiscal 2019.

Product and accessories gross margin as a percentage of product and accessories revenue decreased to (15)% during Fiscal 2021 from 0% during Fiscal 2020, primarily driven by the warranty reserve mentioned above. Parts and service gross margin as a percentage of parts and service revenue improved to 40% for Fiscal 2021 compared to 27% for Fiscal 2020 primarily due to Fiscal 2020 being burdened by higher FPP costs as we worked through the part defect from a supplier identified during the first quarter of Fiscal 2019.

Research and Development Expenses (“R&D”)  R&D expenses for Fiscal 2021 decreased $1.2 million, or 34%, to $2.4 million from $3.6 million for Fiscal 2020, as a result of lower costs from our COVID-19 Business Continuity Plan.

Selling, General and Administrative (“SG&A”) Expenses  SG&A expenses for Fiscal 2021 decreased $3.8 million, or 17%, to $18.4 million from $22.2 million for Fiscal 2020. The net decrease in SG&A expenses was primarily due to cost savings from our COVID-19 Business Continuity Plan which comprised of decreases of approximately $1.5 million in labor costs, $1.1 million in travel and entertainment expense, $0.1 million in consulting expense and $0.1 million in supplies expense, additionally there was a $1.0 million decrease in facilities costs driven by our consolidation of facilities.

Interest Expense  Interest expense for Fiscal 2021 and 2020 were each $5.2 million. See Liquidity and Capital Resources below for additional discussion on our interest expense.

48

Table of Contents

Loss on Extinguishment of Debt   We recognized a loss on extinguishment of debt of approximately $4.3 million during Fiscal 2021. The loss on extinguishment of debt comprised of the write-off of approximately $1.5 million of unamortized debt issuance costs, a facility fee in the amount of $1.0 million paid to the lender, an accrual of $1.0 million for anticipated exit fees due upon repayment of the principal balance to the lender, and the fair value of common stock warrants issued to the warrant holder in connection with Amendment No. 3 to the Purchase Warrant of $0.8 million.

Income Tax Provision Income tax expense increased $6,000, or 50%, to $19,000 during Fiscal 2021 from $12,000 during Fiscal 2020. Income tax expense incurred was related to state and foreign taxes. The effective income tax rate of -0.1% differs from the federal and state blended statutory rate of approximately 23.2% primarily as a result of maintaining a full valuation allowance against net deferred tax assets. At March 31, 2021, we had federal and state net operating loss carryforwards of approximately $592.7 million and $163.0 million, respectively, which may be utilized to reduce future taxable income, subject to any limitations under Section 382 of the Internal Revenue Code of 1986. We provided a valuation allowance for 100% of our net deferred tax asset of $159.7 million at March 31, 2021 because the realization of the benefits of these favorable tax attributes in future income tax returns is not deemed more likely than not. Similarly, at March 31, 2020, the net deferred tax asset was fully reserved.

Liquidity and Capital Resources

Our cash requirements depend on many factors, including the execution of our business strategy and plan. Our cash and cash equivalents balances increased $34.4 million during Fiscal 2021, compared to a decrease of $14.6 million during Fiscal 2020. The increase in cash and cash equivalents during Fiscal 2021 compared to the decrease in cash and cash equivalents during Fiscal 2020 was primarily the result of net cash of $19.0 million received from the issuance of $20.0 million in additional senior secured notes under the A&R Note Purchase Agreement with Goldman Sachs Specialty Lending Group, L.P. (“Goldman Sachs”) entered into during the third quarter of Fiscal 2021, net cash proceeds from the sale of our common stock of approximately $15.9 million after deducting commissions paid of approximately $0.5 million and approximately $2.0 million net cash received from the PPP Loan after deducting amounts subsequently repaid, entered into in the first quarter of Fiscal 2021, as described below. Additionally, during the fourth quarter of Fiscal 2021, we received a financial settlement in the amount of $5.0 million arising out of claims pursued in confidential arbitration with such former strategic parts supplier.

During Fiscal 2022, in addition to funding our operations and sustaining capital expenditures, our significant cash requirements include approximately $8.0 million to build our long-term rental fleet to 21.1 MW in accordance with covenants in our Note Purchase Agreement with Goldman Sachs, approximately $5.0 million in interest payments to service the Goldman Sachs Notes, and approximately $5.0 million to replace high-risk parts in fielded units affected by the sub-optimal parts initially provided by the former strategic parts supplier.

On October 1, 2020, we entered into an Amended & Restated Note Purchase Agreement (the “A&R Note Purchase Agreement”) with respect to our existing $30.0 million in outstanding Notes (as defined below) issued to Goldman Sachs. The A&R Note Purchase Agreement amended and restated that certain Note Purchase Agreement, as amended, dated February 4, 2019, by and among the Company, the Collateral Agent and the other parties party thereto. Under the A&R Note Purchase Agreement, we issued $20.0 million in additional Notes. We received net cash proceeds of $19.0 million after deducting a $1.0 million facility fee paid to the lender. The entire principal amount of the Notes is due and payable on October 1, 2023. As of March 31, 2021, $51.0 million in borrowing were outstanding under the Notes, which includes the accrual for an exit fee to be paid at maturity or upon pre-payment.

On April 24, 2020, we received an unsecured loan in the principal amount of $2,610,200 from Western Alliance Bank, an Arizona corporation under the Small Business Administration Paycheck Protection Program enabled by the Coronavirus Aid, Relief and Economic Security Act of 2020 (the “PPP Loan”) and on May 13, 2020, we repaid $660,200 of the PPP Loan in accordance with the Fourth Amendment to the Note Purchase Agreement between the Company and Goldman Sachs. On March 23, 2020 the Company enacted the Business Continuity Plan in response to COVID-19. Beginning March 30, 2020, the Company furloughed approximately 52 employees, leaving behind only staff deemed essential for day-to-day administrative operations for a minimum period of 45 days. Our Leadership Team volunteered to take a 25% temporary salary cut. In addition, approximately 25 other top Company managers volunteered to take a similar 15% reduction in salary and the Board voted to take a temporary 25% reduction in base cash retainer. As a result of the continued global economic slowdown due to COVID-19 and the associated decline in global crude oil prices, we eliminated 26 positions on June 1, 2020. During the period of March 30, 2020 to June 1, 2020, we had a limited production capability of new microturbine products but had pre-built approximately 5.9 MW of microturbine finished goods during March 2020, for shipment during this period of suspended production. On September 28, 2020 salaries were returned to 100% and remaining furloughed employees returned to work. Our vendor supply chain has been impacted by the pandemic; however, we have been able to maintain sufficient supply flow to continue operations of the date hereof. We believe these programs will supplement our current and future available capital resources.

Operating Activities During Fiscal 2021, net cash provided by operating activities was $1.7 million, consisting of a net loss for the period of $18.4 million, offset by cash provided from working capital of $6.4 million and non-cash adjustments (primarily warranty provision, accounts receivable allowances, depreciation and amortization, stock based compensation and inventory provision) of $13.7 million. During Fiscal 2020, net cash used in operating activities was $19.7 million, consisting of a net loss for the period of $21.9 million and cash used for working capital of $4.0 million, offset by non-cash adjustments of $6.2 million.

Table of Contents

The following is a summary of the significant sources (uses) of cash from operating activities (amounts in thousands):

The change in non-cash operating activities during Fiscal 2021 compared to Fiscal 2020 was primarily driven by the loss on extinguishment of debt accounting resulting from entering into the A&R Note Purchase Agreement with Goldman Sachs during Fiscal 2021. Additionally, contributing to the change was warranty expense during Fiscal 2021 as a result of the warranty reserve established related to reliability programs to account for the replacement of remaining high risk failure parts in some of our fielded units due to a supplier defect. The change in accounts receivable during Fiscal 2021 was primarily the result of lower collections from certain customers, compared to Fiscal 2020. The change in inventory was primarily the result of a decrease in both raw materials and finished goods during Fiscal 2021, as we continued to manage inventory alongside the decreases in revenue as a result of the COVID-19 pandemic. The change in accounts payable and accrued expenses was primarily the result of the level of inventory receipts and timing of payments made by us during Fiscal 2021 compared to Fiscal 2020. The change in other operating assets and liabilities during the Fiscal 2021 compared to Fiscal 2020, was primarily the result of decreases in deferred revenue attributable to FPP contracts, customer deposits and our DSS program.

Investing Activities  Net cash used in investing activities of $3.2 million and $4.2 million during Fiscal 2021 and 2020, respectively, related primarily to the additions of our rental fleet of approximately $2.4 million and $3.2 million, respectively. The remaining amounts were primarily for sustaining our production and facilities.

Financing Activities During Fiscal 2021, we generated approximately $36.0 million in cash from financing activities compared to cash generated during Fiscal 2020 of approximately $9.2 million. The funds generated from financing activities during the fiscal year ended March 31, 2021 were primarily the result of $19.0 million in net proceeds from our A&R Note Purchase Agreement with Goldman Sachs, net borrowings under the PPP Loan, as well as $15.9 million in proceeds from the at-the-market offering program described below. The funds generated from financing activities during Fiscal 2020 were primarily the result of proceeds from the September 2019 registered direct offering and proceeds from the at-the-market offering program described below.

At-the-market offerings

On June 7, 2018, we entered into a Sales Agreement with H.C. Wainwright & Co., LLC (the “Sales Agreement”) with respect to an at-the-market offering program (the “ATM Program”) pursuant to which we may offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $25.0 million. We will set the parameters for sales of the shares, including the number to be sold, the time period during which sales are requested to be made, any limitation on the number that may be sold in one trading day and any minimum price below which sales may not be made. During Fiscal 2021, we issued approximately 2.0 million shares of our common stock under the ATM program and the net proceeds to us from the sale of our common stock were approximately $15.9 million after deducting commissions paid of approximately $0.5 million. During our fourth fiscal quarter ended March 31, 2021, we issued 1,242,253 shares of our common stock under the ATM program and the net proceeds to us were approximately $14.5 million after deducting commissions paid of approximately $0.5 million. On July 15, 2020, we entered into an

amendment to the Sales Agreement, which modified the Sales Agreement to, among other things, amend the termination provisions of the Agreement and amend the maximum amount of shares of our common stock that we may offer and sell through or to H.C. Wainwright & Co., LLC from time to time under the ATM Program On March 19, 2021, we entered into a second amendment to the Sales Agreement, which modified the Sales Agreement to, among other things, reflect the Company’s filing of a new Registration Statement on Form S-3 with the SEC on March 22, 2021 and set the maximum amount of shares of our common stock that we may offer and sell through or to H.C. Wainwright at $50.0 million, subject to certain limitations set forth in the amendment. As of March 31, 2021, approximately $3.9 million remained available for issuance with respect to this ATM Program. As of April 14, 2021, upon the effectiveness of the Registration Statement on Form S-3, approximately $50.0 Million remained available for issuance with respect to this ATM Program.

Warrants

Series A Warrants

As of March 31, 2021, there were 271,875 Series A warrants outstanding. 217,875 Series A warrants were issued with an exercise price of $25.50 per share of common stock, are exercisable into an aggregate amount of up to 217,875 shares of our common stock, and have an expiration date of October 25, 2021. 54,000 Series A warrants with anti-dilution provisions were issued with an initial exercise price of $13.40 per share of common stock, are exercisable into an aggregate amount of up to 54,000 shares of our common stock, and have an expiration date of April 22, 2021. As of March 31, 2021, because of the anti-dilution provisions, these warrants had an adjusted exercise price of $1.15 per share of common stock.

On February 4, 2019, we sold to Goldman Sachs & Co. LLC (the “Holder”), a Purchase Warrant for shares of our common stock (the “Warrant”) pursuant to which the Holder may purchase shares of the Company’s common stock in an aggregate amount of up to 404,634 shares (the “Warrant Shares”). Our common stock and warrant transactions during Fiscal 2021 triggered certain anti-dilution provisions in the warrants outstanding. As of March 31, 2021, the Holder may purchase shares of the Company’s common stock in an aggregate amount of up to 463,067 shares at an exercise price of $2.61.

Goldman “2020 Warrant”

On October 1, 2020, the Company entered into an Amendment No. 3 to the Purchase Warrant for shares of our common stock (the “Amendment No. 3”) with Special Situations Investing Group II, LLC (as successor in interest to Goldman Sachs & Co. LLC) (the “Warrant Holder”) that amended that certain Purchase Warrant for shares of our common stock originally issued by the Company to Goldman Sachs & Co. LLC, dated February 4, 2019, as amended (the “Original Warrant”). As of March 31, 2021, the holder may purchase shares of the Company’s common stock in an aggregate amount of up to 291,295 shares at an exercise price of $4.76.

September 2019 Pre-Funded and Series D Warrants

On September 4, 2019, we entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain institutional and accredited investors pursuant to which we agreed to issue and sell in a registered direct offering (the “Registered Direct Offering”) an aggregate of 580,000 shares of our common stock at a negotiated purchase price of $5.00 per share, and pre-funded warrants to purchase up to an aggregate of 440,000 shares of our common stock at a negotiated purchase price of $5.00 per Pre-Funded Warrant, for aggregate gross proceeds of approximately $5.1 million (580,000 shares of common stock plus 440,000 pre-funded warrants at a $5.00 per share purchase price), before deducting placement agent fees and other offering expenses.

In a concurrent private placement, we agreed to issue to the purchasers warrants to purchase 765,000 shares of common stock, which represent 75% of the number of shares of common stock and shares underlying the Pre-Funded Warrants purchased in the Registered Direct Offering, pursuant to the Securities Purchase Agreement. The Common Warrants are exercisable for shares of common stock at an initial exercise price of $6.12 per share for a period of five years, starting on April 2, 2020 and expiring on April 2, 2025. In January 2021, three warrant holders exercised their rights to the warrant agreement to exercise on a cashless basis 690,000 Series D warrants at an exercise price of $6.12 per share

under the warrant agreement. In accordance with terms of the warrant agreement, after taking into account the shares withheld to satisfy the cashless exercise option, we issued 352,279 shares of common stock. As of March 31, 2021, there were 75,000 Series D warrants outstanding at an exercise price of $6.12.

There were no stock options exercised during Fiscal 2021 and 2020. Repurchases of shares of our common stock for employee taxes due upon vesting of restricted stock units, net of employee stock purchases, resulted in approximately $0.1 million of net cash used during Fiscal 2021 and 2020.

Three-year Term Note  On February 4, 2019, we entered into a Note Purchase Agreement, by and among us, certain subsidiaries of us as guarantors, Goldman Sachs Specialty Lending Holdings, Inc., as collateral agent and any other Purchasers party thereto from time to time , in connection with the sale of senior secured notes of us in a private placement exempt from registration under the Securities Act of 1933, as amended. Under the Note Purchase Agreement, we sold to the Purchaser $30.0 million aggregate principal amount of senior secured notes (the “Notes”). The first interest payment on the Notes was on March 31, 2019. On October 1, 2020,  pursuant to A&R Note Purchase Agreement, we increased the amount of borrowing under the Notes by $20.0 million to $50.0 million, and all outstanding Notes bear interest at the Adjusted (London Interbank Offer) LIBO Rate (as defined in the A&R Note Purchase Agreement) plus 8.75% per annum. The Notes do not amortize and the entire principal balance is due in a single payment on the maturity date. As of March 31, 2021, $51.0 million in borrowings were outstanding under the Notes, which includes the accrual for an exit fee to be paid at maturity or upon pre-payment. Pursuant to the First Amendment to the A&R Note Purchase dated as of May 13, 2021, the minimum consolidated liquidity requirement increased from $9.0 million to $12.0 million.  As of March 31, 2021, we were in compliance with the covenants contained in the A&R Note Purchase Agreement.

Paycheck Protection Program Loan  On April 15, 2020, we applied for an unsecured PPP Loan in the principal amount of $2,610,200 under the Small Business Administration Paycheck Protection Program enabled by the Coronavirus Aid, Relief and Economic Security Act of 2020. On April 24, 2020, we entered into a promissory note with Western Alliance Bank. The Company received the full amount of the PPP Loan on April 24, 2020. In accordance with the requirements of the CARES Act, we intend to use proceeds from the PPP Loan to support fixed costs such as payroll costs, rent and utilities. On May 13, 2020, we repaid $660,200 of the PPP Loan in accordance with the Fourth Amendment to the Note Purchase Agreement between the Company and Goldman Sachs Specialty Lending Group, L.P.

The advance under the PPP Loan bears interest at a rate per annum of 1%. The PPP Loan matures on April 24, 2022.

The PPP Loan may be forgiven partially or fully if the funding received is used for payroll costs, interest on mortgages, rent, and utilities, provided that at least 75% of the forgiven amount has been used for payroll costs. Forgiveness is based on the Company maintaining, or quickly rehiring employees and maintaining applicable salary levels.

Forgiveness will be reduced if full-time headcount declines, or if salaries and wages decrease. Any forgiveness of the PPP Loan shall be subject to approval of the SBA and will require the Company and Western Alliance to apply to the SBA for such treatment in the future.

In January 2021, management applied for forgiveness on the PPP Loan. Management will account for forgiveness on the PPP Loan in accordance with ASC 470 and record a gain on extinguishment of debt on its condensed consolidated financial statements and related footnote disclosures, provided forgiveness be approved by the SBA. In February 2021, the Company applied for forgiveness of the original balance in full and is awaiting for review and approval. No assurance can be provided that forgiveness of any portion of the PPP loan will be obtained.

Working Capital Cash provided from working capital was $6.4 million during Fiscal 2021, an improvement of $10.4 million from the cash used for working capital of $4.0 million during Fiscal 2020. These decreases in cash used for working capital and other operating assets and liabilities were primarily due to reductions in inventory and accounts payable payments, partially offset by an increase in accounts receivable and changes in customer deposits.

Evaluation of Ability to Maintain Current Level of Operations In connection with preparing the consolidated financial statements for the fiscal year ended March 31, 2021, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about our ability to meet our obligations as they became

53

Table of Contents

due for the next twelve months from the date of issuance of our Fiscal 2021 consolidated financial statements. Management assessed that there were such conditions and events, including a history of recurring operating losses, negative cash flows from operating activities, the continued negative impact by the volatility of the global oil and gas markets, a strong U.S. dollar in certain markets making our products more expensive in such markets, the COVID-19 pandemic, and ongoing global geopolitical tensions. We incurred a net loss of $18.4 million and provided cash from operating activities of $1.7 million during the Fiscal 2021. Our working capital requirements during Fiscal 2021 were in-line with management’s expectations, which included reductions in inventory and accounts payable primarily due to our lower revenue levels. Our net loss improved during Fiscal 2021 primarily due to reduced overhead and operating expenses resulting from our COVID-19 Business Continuity Plan, as well as reduced FPP costs as our reliability improved due to the reduced impact of the part defect from a supplier first identified during the first quarter of Fiscal 2019. As of March 31, 2021, we had cash and cash equivalents of $49.5 million, and outstanding debt of $51.0 million at fair value (see Note 11–Term Note Payable in the Notes to the Consolidated Financial Statements for further discussion of the outstanding debt).

Depending on the timing of our future sales and collection of related receivables, managing inventory costs and the timing of inventory purchases and deliveries required to fulfill the backlog, our future capital requirements may vary materially from those now planned. The amount of capital that we will need in the future will require us to achieve significantly increased sales volume which is dependent on many factors, including:

Our accounts receivable balance, net of allowances, was $20.6 million and $16.2 million as of March 31, 2021 and 2020, respectively. Days sales outstanding in accounts receivable, (“DSO”), increased to 105 days as of March 31, 2021, compared to 85 days as of March 31, 2020 due to delayed collections in all markets due to the COVID-19 pandemic and the weakening oil and gas markets. We recorded net bad debt recovery of approximately $0.2 million and net bad debt expense of approximately $0.4 million, for Fiscal 2021 and 2020, respectively. Our allowance for doubtful accounts, was $0.3 million and $0.7 million as of March 31, 2021 and 2020, respectively.

No assurances can be given that future bad debt expense will not increase above current operating levels. Increased bad debt expense or delays in collecting accounts receivable could have a material adverse effect on cash flows and results of operations. In addition, our ability to access the capital markets may be severely restricted or made very expensive at a time when we need, or would like, to do so, which could have a material adverse impact on our liquidity and financial resources. Certain industries in which our customers do business and certain geographic areas have been and could continue to be adversely affected by the previously referenced economic and geopolitical considerations.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of

Capstone Green Energy Corporation

​

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Capstone Green Energy Corporation (the “Company”) as of March 31, 2021 and 2020, the related consolidated statements of operations, stockholders’ equity and cash flows for each of the two years in the period ended March 31, 2021 and 2020, and the related notes (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 March 31, 2021 and 2020, and the results of its operations and its cash flows for each of the two years in the period ended March 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit[s] to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provides a reasonable basis for our opinion.

Critical Audit Matters

​

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

​

Accounts Receivable Allowances

​

Description of Matter

​

As described in Note 2 to the consolidated financial statements, management maintains allowances for estimated losses resulting from the inability of customers to make required payments and other accounts receivable allowances.

F-2

Table of Contents

The principal considerations for our determination that performing procedures relating to the accounts receivable allowances is a critical audit matter are (i) the significant judgement by management when determining the estimate for the accounts receivable allowances; and (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures to evaluate management’s estimate and significant assumptions related to the customers continued ability to make required payments.

​

How We Addressed the Matter

​

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others, testing management’s process for determining the accounts receivable allowances. Procedures related to management’s estimate included evaluating the appropriateness of the method used by management, the completeness, accuracy, and relevance of underlying data used in the estimate, and the reasonableness of significant assumptions used by management in estimating the customers continued ability to make required payments. Evaluating management’s assumptions relating to customers’ credit worthiness, historical payment experience with the customer, and the customers’ new business opportunities.

​

Extended Warranty – Powerhead Failure

​

Description of Matter

​

As described in Note 6 to the consolidated financial statements, management accrued an extended warranty to account for the replacement of high risk failure parts in fielded systems due to a supplier defect. Management’s estimate of this extended warranty liability is generally affected by historical failure rates within a certain population of components, repair costs, and the point of failure within the product life cycle.

​

The principal considerations for our determination that performing procedures relating to the extended warranty liability is a critical audit matter are (i) the significant judgement by management when determining the estimate for the extended warranty liability; and (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures to evaluate management’s estimate and significant assumptions related to historical failure rates, repair costs, and the point of failure within the product life cycle.

​

How We Addressed the Matter

​

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others, testing management’s process for determining the extended warranty liability. Procedures related to management’s estimate included evaluating the appropriateness of the method used by management, the completeness, accuracy, and relevance of underlying data used in the warranty estimate, and the reasonableness of significant assumptions used by management in estimating the extended warranty liability related to the component failure rates, repair costs, and the point of failure within the product life cycle. Evaluating management’s assumptions relating to the component failure rates, repair costs, and the point of failure within the product life cycle involved evaluating whether the assumptions were reasonable considering historical product experience of the Company.
