to operate which may require modification and updates over the life of such systems. Software is inherently complex and often contain defects and errors when first introduced. These defects and errors can manifest in any number of ways in our power systems, including through diminished performance, security vulnerabilities, malfunctions, or even permanently disabled products. Additionally, it is difficult for us to evaluate the manufacturing, assembly and construction of our power systems until there are working examples that have been manufactured, assembled, constructed and used by us and/or our customers. There can be no assurance that we will be able to detect and fix any defects in the hardware or software of our power systems, and such defects may not become apparent until a system is installed and operational. In the ordinary course of our business, we have experienced defects that were discovered once our power systems were Table of Contents

deployed in the field. Changes in our supply chain or the failure of our suppliers to otherwise provide us with components or materials that meet our specifications could also introduce defects
in our power systems. If any of our power systems are defective or fail because of their design, including those incorporating third-party hardware, or if changes in applicable laws or regulations, or in the enforcement thereof, require us to
redesign or recall our power systems, we may incur additional costs and expenses. The process of identifying and recalling a power system or a component thereof may be lengthy and require significant resources and divert the attention of our
engineering personnel from our power system development efforts, and we may incur significant replacement costs, contract damage claims from our customers, product liability, property damage, personal injury or other claims and liabilities, and
brand and reputational harm. Significant costs or payments made in connection with generator warranty and product liability claims and power systems recalls could harm our financial condition and results of operations.

Our power systems may not perform consistently with customers’ expectations or consistent with other distributed power
systems that may become available. Any defects or any other failure of our power systems to perform as expected could harm our reputation and result in negative publicity, lost revenue, delivery delays, product liability claims and significant
generator warranty and other expenses, and could have a material adverse effect on our business, financial condition, results of operations and prospects. Any defects, errors or other vulnerabilities discovered in our software after release could
allow third parties to access, manipulate or exploit our software and expose us to claims for damages, any of which could seriously harm our business. We also could face claims for product liability, tort or breach of warranty. Defending a lawsuit,
regardless of its merit, is costly and may divert management’s attention and seriously harm our reputation and our business.

The performance of our power systems could be adversely affected by various operating risks and factors outside of our control, which
could result in harm to our reputation, business, financial condition and results of operations.

Our power systems
are subject to various operating risks that may cause them to generate less value for our customers than expected. These risks include a failure or wearing out of our equipment or the equipment that our equipment connects into, an inability to find
suitable replacement equipment or parts, or disruption in our power systems. Any extended interruption or failure of our power systems, including systems we operate under O&M and asset management agreements, for any reason to generate the
expected amount of output could adversely affect our business, financial condition, results of operations and reputation. We also provide performance guarantees to our customers covering the performance of our power systems, and failure to meet such
performance requirements could result in liquidated damages or penalties and adversely impact our customers’ willingness to acquire additional power systems or services and our ability to attract new customers.

Field conditions, such as the quality of the fuel supply and environmental factors, can impact the performance of our power
systems in unpredictable ways. As we move into new geographies and deploy new features, technologies and service configurations, we encounter new field conditions from time to time (including as a result of climate change). Adverse impacts on
performance may require us to incur significant service and re-engineering costs or divert the attention of our engineering personnel from product development efforts. Furthermore, we may be unable to
adequately address the impacts of factors outside of our control in a manner satisfactory to our customers. Any of these circumstances could materially and adversely affect customer satisfaction, market acceptance and our reputation, business,
financial condition and results of operations.

The failure of our third-party suppliers to deliver the necessary components or
materials of our power systems in a timely manner and to the required specifications could prevent us from delivering our power system solutions within required timeframes and could cause installation delays, cancellations, penalty payments and
damage to our reputation.

We rely or may in the future rely on third-party suppliers for the components or certain
raw materials of our power systems, including alternators, engine blocks, engine controllers, catalysts, steel, copper, aluminum,

Table of Contents

certain precious metals and other materials that may be of limited supply. We are also reliant on third-party suppliers for certain infrastructure equipment, pipelines and other materials and
technologies that are necessary to install and operate our power systems. If we fail to develop or maintain our relationships with our suppliers, or if any of these suppliers reduce or eliminate the supply of components or other necessary materials
for the assembly and installation of our power systems to us in the future, or if there is otherwise a shortage or lack of availability of such components or materials, we may be unable to produce or install our power systems or our power systems
may be available only at a higher cost or after a long delay. Such delays could prevent us from delivering our power systems to our customers within required timeframes and cause order cancellations. Delays in our suppliers’ deliveries have
impaired and may in the future impair our ability to deliver power systems to our customers.

The timing of purchases in
future periods could differ materially from our estimates due to fluctuations in demand requirements related to varying sales levels as well as changes in economic conditions. Further, the revenues that our third-party suppliers generate from our
orders may represent a relatively small percentage of their overall revenues, and while we seek to negotiate supply agreements with all of our suppliers, we may purchase some products or components on a purchase order basis. As a result, fulfilling
our orders may not be considered a priority to these suppliers in the event of constrained ability to fulfill all of their customer obligations in a timely manner. Certain of our suppliers also supply parts and materials to other businesses,
including businesses engaged in other industries unrelated to natural gas power systems. As a relatively low-volume purchaser of certain of these parts and materials, we may be unable to procure a sufficient
supply of the items in the event that our suppliers fail to produce sufficient quantities to satisfy the demands of all of their customers, which could materially harm our financial condition and results of operations.

The number of suppliers we have or may have in the future for some of our components or materials is or may be limited and in
some cases sole-sourced. Our reliance on third-party suppliers makes or may make us vulnerable to possible capacity constraints and reduced control over component or materials availability, delivery schedules, quality issues, manufacturing yields
and costs. We use certain custom components and materials in our power systems. We design and engineer these components and we have relationships with suppliers that will manufacture these components for us. The design, engineering, manufacturing
setup, and quality control activities are time and capital intensive. Some of our suppliers use proprietary processes to manufacture components. We may be unable to obtain comparable components from alternative suppliers without considerable delay,
expense or at all, as replacing these suppliers could require us either to make significant investments to bring the capability in house or to invest in a new supplier partner. Some of our suppliers are smaller, private companies, heavily dependent
on us as a customer. If our suppliers face difficulties obtaining the credit or capital necessary to expand their operations when needed, they could be unable to supply necessary components or materials needed to support our planned sales and
services operations, which would negatively impact our sales volumes and cash flows.
