PART I.

ITEM 1. BUSINESS

Our New Strategy

In October 2024, we announced a new business strategy that reflects a renewed focus on developing and marketing our AI-enabled software and services offerings. This transition will entail significant operational changes, including reduction of what has historically been the source of most of our revenue (battery hardware resales), adjustments to the way we develop and market our products and services, and realignment of our business processes. These changes are expected to result in reduced revenue, restructuring-related costs and short-term disruptions in our operations, which may negatively affect our ability to effectively scale our software and services offerings and achieve our financial and operational targets. Failure to successfully and timely implement our new strategy may have a material adverse effect on our business, financial condition, and results of operations. See “We may not be able to successfully implement our recently announced new strategy.” in Part I. Item 1A. “Risk Factors” in this Report for additional information about some risks related to our new strategy.

Overview

Stem, Inc., a Delaware corporation (“Stem,” the “Company,” “we,” “us,” or “our”), is a global leader in artificial intelligence (“AI”)-driven software and services that enable its customers to plan, deploy, and operate clean energy assets. We offer a comprehensive suite of solutions that are designed to transform how solar and energy storage projects are developed, built, and operated, including (i) an integrated suite of software and edge hardware products, and (ii) full-lifecycle energy services from a team of industry experts. More than 16,000 global customers rely on Stem to maximize the value of their clean energy projects and portfolios.

Since our inception in 2009, we have engaged in developing and marketing AI-enabled software and services, raising capital, recruiting personnel, and growing our annual recurring revenue. As the energy landscape has changed in recent years, we have increasingly focused on larger, utility-scale projects, supporting asset owners, developers, utilities, operators, and traders. Over the last 15 years, we have grown into one of the most experienced clean energy software providers in the world, achieving milestones such as deploying software with multiple Fortune 500 companies, operating the largest virtual power plant in California, and becoming the de facto standard for commercial and industrial solar asset management software.

We operate in two key areas within the renewable energy landscape: solar and storage. In solar, we serve project developers, asset owners and engineering, procurement and construction firms (EPCs) by selling them solar edge devices and monitoring and control software, as well as professional services related to the design and commissioning of the same.

In storage, we serve project developers, asset owners, EPCs, and distributors by selling them software-enabled forecasting and optimization managed services that minimize spending on utility bills, or maximize revenue from energy market participation. In some cases, we also resell battery OEM hardware to our customers for a fee.

Some customers own both solar and storage assets, and use our full software capabilities and services across both asset classes.

Our suite of software applications is enabled by our AI platform, Athena®. Each application helps customers maximize the value of their energy assets. Our asset performance management (APM) application, PowerTrackTM APM, provides a unified solution that empowers asset owners and operators to efficiently monitor and control complex storage, solar, and hybrid portfolios for optimal performance. Our Energy Management System (EMS) application, PowerCoreTM EMS, is a technology-agnostic, edge-to-cloud integration solution for monitoring, managing, and controlling energy storage and hybrid systems for maximum performance and reliability. Our energy storage optimization application, PowerBidderTM Pro, combines Athena’s wholesale market bidding engine with a web interface, allowing users to choose between automated and user-defined trading strategies. To complement our software applications, we manufacture commercial- and utility-scale edge hardware solutions. These edge devices function across solar and storage products from multiple original equipment manufacturer (“OEM”). As of December 31, 2024, Athena had accumulated more than 43 million runtime hours, with more than 500,000 industrial Internet of Things (“IoT”) devices under management, across more than 178,500 sites in 57 countries.

We also deliver software-enabled managed services to our customers through the Athena AI platform. We believe that the network created by our growing customer base increases grid resilience and reliability through the real-time balancing of market-based supply and demand signals. Additionally, our solutions are designed to support renewable energy generation by helping to alleviate grid intermittency issues, thereby reducing customer dependence on traditional, fossil fuel-based power generation resources.

To help our customers achieve long-term performance and profitability goals for their energy projects, we also provide advisory services spanning development and engineering, procurement and integration, and performance and operation services. In the early stages of project planning, our experts help lay a solid foundation for our customers’ solar and storage

4

projects by guiding the design and ensuring informed decision-making. During the building stage, we provide guidance for hardware procurement and integration for timely deployment. After assets are operational, we enable optimal economic and technical returns with managed energy services such as trading and bidding strategies, wholesale market participation, performance reporting, system warranties, and more.

History

We were originally known as Star Peak Energy Transition Corp. (“STPK”), which was a special purpose acquisition company that completed its public offering on August 20, 2020. On April 28, 2021 (the “Closing Date”), we consummated a business combination (the “Merger”) pursuant to an Agreement and Plan of Merger by and among STPK, STPK Merger Sub Corp., a Delaware corporation and wholly-owned subsidiary of STPK (“Merger Sub”), and Stem, Inc., a Delaware corporation (“Legacy Stem”). The Merger was effected on the Closing Date through the merger of the Merger Sub with and into Legacy Stem, with Legacy Stem surviving as a wholly-owned subsidiary of the Company. Legacy Stem was a private company and is considered the Company’s accounting predecessor.

On April 3, 2023, we issued $240.0 million aggregate principal amount of 4.25% Green Convertible Senior Notes due 2030 (the “2030 Convertible Notes”) in a private placement offering to qualified institutional buyers (the “2023 Initial Purchasers”) pursuant to Rule 144A under the Securities Act of 1933, as amended. The 2030 Convertible Notes are senior, unsecured obligations of the Company and bear interest at a rate of 4.25% per year, payable in cash semi-annually in arrears in April and October of each year, beginning in October 1, 2023. The notes will mature on April 1, 2030, unless earlier repurchased, redeemed or converted in accordance with their terms prior to such date. Upon conversion, we may choose to pay or deliver cash, shares of common stock or a combination of cash and shares of common stock. The notes are redeemable for cash at our option at any time given certain conditions.

Our net proceeds from this offering were approximately $232.4 million, after deducting for $7.6 million of debt issuance costs primarily consisting of underwriters, advisory, legal, and accounting fees. On April 3, 2023, we used approximately $99.8 million of the net proceeds to purchase and surrender for cancellation approximately $163.0 million aggregate principal amount of our 0.50% Green Convertible Notes due 2028 (the “2028 Convertible Notes”).

On March 29, 2023 and March 31, 2023, in connection with the pricing of the 2030 Convertible Notes, and on April 3, 2023, in connection with the exercise in full by the 2023 Initial Purchasers of their option to purchase additional notes, we entered into Capped Calls (the “2030 Capped Calls”) with certain counterparties. We used $27.8 million of the net proceeds from the 2030 Convertible Notes to pay the cost of the 2030 Capped Calls.

solar deployment for Neovolt, one of the largest renewable asset owners in Hungary, who will standardize its asset management on PowerTrack.

Research and Development

We have invested significant amounts of time and expense in the development of our software. The ability to maintain our leadership position depends in part on our ongoing research and development activities. Our software development, data science, and product professionals are responsible for the design, development, integration, and testing of our software products. We focus our efforts on developing our software to improve our algorithms, augment value with new revenue streams and localize our capabilities based on geography and regulatory considerations.

Intellectual Property

Intellectual property is a key differentiator for our business, and we seek protection whenever possible for the intellectual property that we own and control, including but not limited to patents, proprietary information, trade secrets and software tools and applications. We rely upon a combination of patent, copyright, trade secret and trademark laws, as well as employee and third-party non-disclosure agreements and other contractual restrictions to establish and protect our proprietary rights.

We have developed a significant patent portfolio to protect elements of our proprietary technology. As of December 31, 2024, we had more than 80 patents across storage and solar asset performance.

Our intellectual property encompasses a diverse mix of patents with respect to our proprietary systems and software. These patents relate to the following broad categories:

•power electronics, including the basic interaction of batteries with the power grid where such electronics convert direct current (DC) battery power to alternating current (AC) compatible grid power;

•analytics and control, including use cases and decisions into the operation of an energy storage system and the coordination of providing economic or operational value to a customer;

•networked operations and grid services that involve the aggregation and operation of a group of energy storage systems to provide value to a utility or grid operator; and

•monitoring and control of solar photo-voltaic power assets along with fault detection, performance analytics and solar generation forecasting.

“Athena®” is a registered-trademark, and Athena’s trademarked applications include “AnalyzerTM,” “SupervisorTM,” “ExplorerTM,” and “PowerBidderTM.” The services relating to these trademarks include, but are not limited to, energy optimization services, software as a service for energy optimization services and energy storage charge and discharge.

We routinely review our development efforts to assess the existence and patentability of our intellectual property. We pursue the registration of our domain names and trademarks and service marks in the U.S. In an effort to protect our brand, as of December 31, 2024, we had nine registered trademarks in the U.S.

Competition

The clean energy industry is highly competitive, and new regulatory requirements for carbon emissions, technological advances, the lower cost of renewable energy, the decrease in battery and solar panel costs, improving battery technology and shifting customer demands are causing the industry to evolve and expand. We believe that the principal competitive factors in the clean energy market include, but are not limited to:

•safety, reliability and quality;

•product performance and uptime;

•historical track record and references for customer satisfaction;

•experience in proving bankability for multiple stakeholders;

•technological innovation;

•comprehensive solution from a single provider;

•upfront and ongoing costs of software and services;

•ease of integration and clarity of value proposition; and

6

•seamless edge hardware, software, and service offerings.

There is rising demand for solutions that enable the deployment and operation of clean electric power assets with high availability and performance. Additionally, the transition to renewable energy sources and distributed energy infrastructure has increased the complexity and variability of power generation and end-customer electricity demand. This industry transformation has created an opportunity for an increased role for clean energy software and services like ours. We believe that these trends will drive C&I customers, utilities, independent power producers and project developers to grow their use of and investment in clean energy systems.

Our key competitors include energy monitoring and optimization software providers, energy storage and edge device OEMs, hardware integration providers, renewable project developers, EPC firms, and consulting firms. In storage, our competitors are typically focused on the development and marketing of single-purpose built solutions with captive hardware offerings, while our AI-powered software is hardware agnostic, and benefits from operational data across a multitude of hardware types, geographies, utilities, and grid operator service areas. In solar, our competitors provide monolithic software and edge devices, whereas PowerTrackTM and our edge devices provide customers with a flexible solution that meets their individual project needs.

We believe we are well-positioned to compete successfully in the market for software and software-enabled services. We are among the leaders in global distributed solar and energy storage assets under management, supported by proven technology, focused customer service, strong strategic partnerships and a seasoned leadership team with a track record of success.

Government Regulation and Compliance

There are varying policy frameworks across the U.S. and abroad designed to support and accelerate customer adoption of clean and reliable distributed generation technologies. These policy initiatives come in the form of tax incentives, cash grants, performance incentives and electric tariffs.

Our AI-powered platform manages energy assets operating worldwide, with various policy frameworks across each energy market. Several U.S. states have utility procurement programs, energy system decarbonization goals and/or renewable portfolio standards for which our technology is eligible, including California, Connecticut, Hawaii, Illinois, Massachusetts, Maryland, Michigan, New Jersey, New York and Texas. Additionally, these energy assets often qualify for tax or financial incentives and, following passage of the United States Inflation Reduction Act of 2022 (the “IRA”), provisions such as the storage investment tax credit (ITC) and solar production tax credit (PTC), among others, provide additional federal incentives. However, the availability, value, or implementation of federal incentives could also change with political conditions including those related to Congress or the presidency.

Federal, state and local government statutes and regulations concerning electricity heavily influence the demand for our products and services even though we are not regulated as a utility. These statutes and regulations often relate to electricity pricing, net metering, incentives, taxation, competition with utilities and the interconnection of customer-owned electricity generation. In the U.S., governments, often acting through state utility or public service commissions, change and adopt different rates for commercial customers on a regular basis. These changes can have a positive or negative effect on our ability to deliver cost savings or revenue generation for our customers.

Several states have mandates or policies designed to encourage energy storage adoption. For example, California offers a cash rebate for storage installations through the Self Generation Incentive Program and Massachusetts and New York offer performance-based financial incentives for storage. Storage installations also are supported in some states by state public utility commission policies that require utilities to consider alternatives such as storage before they can build new generation. In February 2018, the Federal Energy Regulatory Commission (“FERC”) issued Order 841, directing regional transmission operators and independent system operators to remove barriers to the participation of storage in wholesale electricity markets and to establish rules to help ensure storage resources are compensated for the services they provide. In September 2020, the FERC issued Order 2222, opening up U.S. wholesale energy markets to aggregations of distributed energy resources like rooftop solar, BTM batteries, and electric vehicles. FERC Order 2222 is currently in the implementation stage.

Solar and energy storage systems require interconnection agreements from the applicable local electric utilities in order to connect to the grid and operate. In almost all cases, interconnection agreements are standard form agreements that have been pre-approved by the local public utility commission or another regulatory body with jurisdiction over interconnection agreements. As such, no additional regulatory approvals are typically required once interconnection agreements are signed. For wholesale transmission, energy storage systems require interconnection agreements with transmission providers. The pace of

7

wholesale interconnection is often a source of delay for project implementation, although FERC is requiring process improvements through Order 2023, which is an ongoing proceeding.

Our operations are subject to stringent and complex federal, state, and local laws and regulations governing the occupational health and safety of our employees and wage regulations. For example, we are subject to the requirements of the federal Occupational Safety and Health Act (“OSHA”), as amended, and comparable state laws that protect and regulate employee health and safety.

There are government regulations pertaining to battery safety, transportation of batteries, tariffs, and disposal of hazardous materials. We and our suppliers, as applicable, are required to comply with these regulations in order to sell our batteries into the market. The license and sale of our batteries and technology abroad is likely to be subject to export controls in the future.

Each installation must be designed, constructed, and operated in compliance with applicable federal, state, and local regulations, codes, standards, guidelines, policies, and laws. To install and operate energy storage systems on our platform, we, our customers or our partners are required to obtain applicable permits and approvals from various authorities with jurisdiction over energy storage systems and interconnection.

Risks Related to Our Business and Industry

Our limited operating history at current scale and our nascent industry make evaluating our business and prospects difficult.

From our inception in 2009 through 2012, we were focused principally on research and development activities relating to our energy storage systems technology. We did not sell any of our battery hardware and software-enabled services and did not recognize any significant revenue until much later. Moreover, in October 2024, we announced a new business strategy that reflects a renewed focus on developing and marketing our AI-enabled software and services offerings. Our new strategy will require significant operational changes, including reduction of what has historically been the source of most of our revenue (battery resales), adjustments to the way we develop and market our products and services, and realignment of our business processes. As a result, we have a limited history operating our business at its current scale and under our new strategy, and therefore a limited history upon which you can base an investment decision.

There is rising demand for clean electric power solutions that can provide electric power with lower carbon emissions with high availability. One such solution is distributed, renewable energy generation, which is supplementing and replacing conventional generation sources, given its increasingly compelling economics. Among other renewable energy market trends, we expect our business results to be driven by declines in the cost of generation of renewable power both on an absolute basis and relative to other energy sources (as evidenced by current solar and wind generation deployments), decreases in the cost of manufacturing battery packs and a rapidly growing energy storage market driven by increasing demand from commercial and industrial customers, utilities and grid operators. However, predicting our future revenue and appropriately budgeting for our expenses is difficult, and we have limited insight into trends that may emerge and affect our business.

The distributed generation industry is emerging and our distributed generation offerings may not receive widespread market acceptance.

The implementation and use of distributed generation at scale is still relatively nascent, and we cannot be sure that potential customers will accept our services and solutions broadly. Enterprises may be unwilling to adopt our offerings over traditional or competing power sources for any number of reasons, including the perception that our technology is unproven, lack of confidence in our business model, unavailability of back-up service providers to operate and maintain the energy storage systems, and lack of awareness of our related products and services. Because this is an emerging industry, broad acceptance of our products and services is subject to a high level of uncertainty and risk. If the market develops more slowly than we anticipate, our business may be adversely affected.

If renewable energy technologies are not suitable for widespread adoption, or if sufficient demand for our software-enabled services does not develop or takes longer to develop than we anticipate, our sales may decline and we may be unable to achieve or sustain profitability.

The market for renewable, distributed energy generation is emerging and rapidly evolving, and its future success is uncertain. If renewable energy generation proves unsuitable for widespread commercial deployment or if demand for our renewable energy products and services fails to develop sufficiently, our revenue, market share and profitability would be adversely impacted.

Many factors may influence the widespread adoption of renewable energy generation and demand for our products and services, including, but not limited to the cost-effectiveness of renewable energy technologies as compared with conventional and competitive technologies, the performance and reliability of renewable energy products as compared with conventional and non-renewable products, fluctuations in economic and market conditions that impact the viability of conventional and competitive alternative energy sources, increases or decreases in the prices of oil, coal and natural gas, continued deregulation of the electric power industry and broader energy industry, and the availability or effectiveness of government subsidies and

12

incentives. You should consider our prospects in light of the risks and uncertainties emerging companies encounter when introducing new products and services into a nascent industry.

If the estimates and assumptions we use to determine the size of our total addressable market are inaccurate, our future growth rate may be negatively affected and the potential growth of our business may be limited.

Market estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may prove to be inaccurate. Even if the markets in which we compete meet our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all. The assumptions relating to our market opportunities include, but are not limited to (i) general declines in the cost of renewable energy generation assets and battery energy storage systems; (ii) growing deployment of renewable energy assets and battery energy storage systems; and (iii) continued complexity of the electrical grid and resulting demand for stability and resiliency. Our expected market opportunities are also based on the assumption that our existing and future offerings will be more attractive to our customers and potential customers than competing products and services. If these assumptions prove inaccurate, our business, financial condition and results of operations could be adversely affected.

We currently face and will continue to face significant competition.

We compete for customers, financing partners and incentive dollars with other providers of asset performance monitoring and control solutions and energy storage systems. Many providers of electricity, such as traditional utilities and other companies offering distributed generation products, have longer operating histories, customer incumbency advantages, access to and influence with local and state governments, and more capital resources than we do. Significant developments in alternative energy storage and management technologies or improvements in the efficiency or cost of traditional energy sources, including coal, oil, natural gas used in combustion or nuclear power, may materially and adversely affect our business and prospects in ways we cannot anticipate. We may also face new competitors who are not currently in the market, including as a result of the IRA and its anticipated impacts and benefits to our industry. If we fail to adapt to changing market conditions and to compete successfully with new competitors, we will limit our growth and adversely affect our business results. Additionally, in connection with our new business strategy, we are renewing our focus on developing and marketing our AI-enabled software and services offerings. Our competitors may be able to develop new AI-enabled offerings that negatively impact demand for our offerings, or incorporate AI into their offerings more successfully than we do and achieve greater and faster adoption. As a result, even if our services and offerings are more effective than the products and services that our competitors offer, potential customers might select competitive products and services in lieu of purchasing our services, which would limit our growth and adversely affect our business results.

Our future growth will depend on expanding and diversifying our new product and new market opportunities, and if we do not successfully execute on our new product and new market plans, or if our new product and new market opportunities are more limited than we expect, our operating results and future growth prospects could be adversely affected.

We are attempting to enhance our future growth opportunities by implementing a new business strategy that reflects a renewed focus on developing and marketing our AI-enabled software and services offerings, and investing in the research and development of new offerings. Additionally, we are seeking to expand the markets in which we sell our products and services. If we do not appropriately allocate our resources in line with the market and developing opportunities, our results of operations and future growth prospects could be adversely affected.

Our investments also may not result in the growth we expect, or the timing of when we expect it, for a variety of reasons, including but not limited to, changes in growth trends, evolving and changing markets and increasing competition, market opportunities, and technology and product innovation. We may introduce new technologies or products that do not work, are not delivered on a timely basis, are not developed according to product and/or cost specifications, or are not well received by customers. Moreover, there may be fewer opportunities than we expect due to a decline in business or economic conditions or a decreased demand in these markets or for our new products from our expectations, our inability to successfully execute our sales and marketing plans, or for other reasons. In addition to our current growth opportunities, our future growth may be reliant on our ability to identify and develop potential new growth opportunities. This process is inherently risky and may result in investments in time and resources for which we do not achieve any return or value. These risks are enhanced by attempting to introduce multiple breakthrough technologies and products simultaneously.

Our growth opportunities and those opportunities we may pursue are subject to rapidly changing and evolving technologies and industry standards, and may be replaced by new technology concepts or platforms. If we do not develop innovative and reliable product offerings and enhancements in a cost-effective and timely manner that are attractive to customers in these markets; if we are otherwise unsuccessful in competing in these new product categories; if the new product categories in which we invest our limited resources do not emerge as expected or do not produce the growth or profitability we expect, or when we

13

expect it, or if we do not correctly anticipate changes and evolutions in technology and platforms, our business and results of operations may be adversely affected.

Risks Relating to Our Operations

We may not be able to implement our new strategy. Our failure to do so could adversely affect our business, financial condition, and results of operations.

On October 1, 2024, we announced our new strategy. We identified, among other things, the need to transition from reliance on hardware resales to a software- and services-focused business. While we believe this is critical to our long-term growth and profitability, our implementation of this strategy is subject to numerous risks and uncertainties.

Our total hardware revenue in fiscal years 2024 and 2023 were $76.8 million and $399.0 million, which comprised 53.1% of our total revenue in fiscal year 2024 and 86.4% of our total revenue in fiscal year 2023, respectively. Our transition away from hardware resales is expected to lead to decreased revenue in the short term, as we work to adjust our revenue streams and our customer base. This decline in revenue could strain our cash flow and temporarily worsen our cash position, which in turn may limit our ability to invest in the necessary technologies, talent and infrastructure required to fully implement the new strategy. If we are unable to generate sufficient cash flow or secure additional funding, we may experience delays in executing our new strategy, which could have a material adverse effect on our business, financial condition, and results of operations.

This transition will entail significant operational changes, including reduction of what has historically been the source of most of our revenue (battery resales), adjustments to the way we develop and market our products and services, and realignment of our business processes. These changes could lead to reduced revenue, restructuring-related costs and disruptions in our operations, which may negatively impact our ability to effectively scale our software and services offerings and achieve our financial and operational targets. Failure to successfully and timely implement these changes may have a material adverse effect on our business, financial condition, and results of operations.

Customer acceptance of our software and service offerings is also critical to our future success. Existing customers may not adopt our new offerings at the rate we expect, and new customers may not be attracted to our software-based solutions. If market demand for the types of AI-driven clean energy software and services we are developing and will seek to develop in the future does not grow as anticipated, or if competitors offer more attractive products, our revenue growth and market position could be adversely affected. As with all software offerings, there is also a risk that our solutions could be vulnerable to cybersecurity threats or contain errors, bugs, or other issues affecting their functionality, which could negatively affect customer satisfaction and adoption.

In addition, executing on the new strategy requires investment in new capabilities and resources, particularly in software development, data management, and AI. We may face challenges in recruiting, retaining, and training employees who have the necessary skill sets to support our new business model. A failure to build or acquire these capabilities in a timely manner could delay the successful execution of the strategy and weaken our competitive position.

We are subject to supply chain risk and our suppliers may fail to deliver components according to schedules, prices, quality and volumes that are acceptable to us, which could negatively affect our results of operations.

We purchase our components and materials from international and domestic vendors, and are exposed to supply chain risks arising from logistics disruptions. Unexpected changes in business conditions, the macroeconomic environment, geopolitical instability, materials pricing, including inflation of raw material costs, labor issues, wars, natural disasters, health epidemics, trade and shipping disruptions, port congestions and other factors beyond our or our suppliers’ control could also affect these suppliers’ ability to deliver components to us or to remain solvent and operational. In addition, international supply is also exposed to risks related to tariffs and sanctions, as well as political, social, and economic instability in regions where we source products and material. For example, President Trump has indicated that he intends to impose additional tariffs, including a 60% tariff on goods imported from China and a 20% tariff on all other U.S. imports, which could result in a trade war. These or other tariffs could adversely affect our hardware component prices and negatively affect any plans to sell products in any impacted international markets. Disruptions in the availability of key equipment, components or materials such as lithium may adversely affect our business, prospects and operations, and volatility in prices and availability of such items may negatively affect our customer relationships and ability to plan for future growth.

14

We face risks resulting from supplier concentration and limited supplier capacity.

We currently rely on a very small number of suppliers of energy storage systems and other equipment. If any of our suppliers were unable or unwilling to provide us with contracted quantities in a timely manner at prices, quality levels and volumes acceptable to us, we would have very limited alternatives for supply, and we may not be able to contract for and receive suitable alternative supply in a timely manner for our customers, or at all. Such an event may impair our ability to meet scheduled deliveries of our products to customers, which may cause our customers to cancel orders and subject us to liability, including liquidated damages to our customers, and may materially adversely affect our customer relationships, business, prospects, financial condition and results of operations. We may also be unsuccessful in our continued efforts to negotiate with existing suppliers to obtain cost reductions and avoid unfavorable changes to terms. Global demand has increased for lithium-ion battery cells, which has caused challenges for our suppliers, including delays or price volatility. Any such delays or reduced availability of energy storage systems or other component materials may impact our sales and operating results. Further, these risks may increase as the market demand for our offerings grows. Additionally, some of our suppliers supply systems and components to other businesses, including businesses engaged in the production of consumer electronics and other industries unrelated to energy storage systems. There are also larger purchasers of certain parts and materials that we supply to our customers. As a result, we may be unable to procure a sufficient supply of the items we require in the event that our suppliers fail to produce sufficient quantities to satisfy the demands of all of their customers. Any of these occurrences could materially adversely affect our business, prospects, financial condition and results of operations.

We have entered into long-term supply agreements that could result in insufficient inventory and negatively affect our results of operations.

We have entered into long-term supply agreements with certain suppliers of battery storage systems and other components of our energy storage systems. Some of these supply agreements provide for fixed or inflation-adjusted pricing and substantial prepayment obligations. Additionally, if our suppliers provide insufficient inventory at the level of quality required to meet customer demand, or if our suppliers are unable or unwilling to provide us with the contracted quantities, we will have limited alternatives for supply and our results of operations could be materially and negatively impacted. Further, we face significant specific counterparty risk under long-term supply agreements when dealing with certain suppliers without a long, stable production and financial history.

Some of our suppliers do not have a long operating history and may not have sufficient capital resources. In the event any such supplier experiences financial difficulties, it may be difficult or may require substantial time and expense to replace such a supplier. We do not know whether we will be able to maintain long-term supply relationships with our critical suppliers, or secure new long-term supply agreements. Additionally, we procure many of the battery storage systems and components of our energy storage systems from non-U.S. suppliers, which exposes us to risks, including but not limited to unforeseen increases in costs or interruptions in supply arising from macroeconomic or geopolitical factors and from changes in applicable international trade regulations, such as taxes, tariffs, or quotas. Any of the foregoing could materially adversely affect our business, financial condition and results of operations.

We depend on significant customers for a substantial portion of our revenue. If we fail to retain or expand our customer relationships or significant customers reduce their purchases, our revenue could decline significantly.

We depend on a small number of significant customers for our sales, and a small number of customers have historically accounted for a material portion of our revenue. The loss of any one of our significant customers, their inability to perform under their contracts, their termination or failure to renew their contracts with us, or their default in payment could cause our revenue and our working capital to decline materially. As of December 31, 2024, we had $59.3 million of accounts receivable including $7.8 million of unbilled receivables. For the near future, we may continue to derive a significant portion of our revenue from a small number of customers. For the fiscal year ended December 31, 2024, no one customer accounted for more than 10% of our revenue. Loss of a significant customer or a significant reduction in pricing or order volume from a significant customer could materially reduce our revenue and operating results in any reporting period.

In addition, we are subject to credit risk of our customers, and our operating results depend on receipt of timely payments from our customers. Any delay in payment by our customers may have an adverse effect on revenue and operating results. There is no assurance that we will be able to collect all or any of the amounts owed to us in a timely matter. If any of our customers face unexpected situations such as financial difficulties, we may not be able to receive full or any payment of the uncollected sums or enforce any judgment debts against such clients, and our business, results of operations and financial condition could be materially and adversely affected.

15

Our hardware and software-enabled services involve a lengthy sales and installation cycle. If we fail to close sales on a regular and timely basis, it could adversely affect our business, financial condition and results of operations. Amounts included in our contracted backlog may not result in actual revenue or translate into profits.

Our sales cycle is typically six to 12 months for our hardware and software-enabled services, but can vary considerably. In order to make a sale, we must typically provide a significant level of education to prospective customers regarding the use and benefits of our hardware and software-enabled services.

The period between initial discussions with a potential customer and the sale of even a single energy storage system typically depends on a number of factors, including the potential customer’s budget and decision as to the type of financing it chooses to use, as well as the arrangement of such financing. Prospective customers often undertake a significant evaluation process, which may further extend the sales cycle, and which evaluation may be negatively impacted by general market and economic conditions such as inflation, rising interest rates, availability of capital, a recessionary environment, geopolitical instability, energy availability and costs, and the availability and effects of government initiatives.

Currently, the time between the entry into a sales contract with a customer and the installation of our energy storage systems can range from nine to 18 months, or more. This lengthy sales and installation cycle is subject to a number of significant risks over which we have little or no control. We characterize contracts that have been signed but not yet installed as a booking that becomes part of our backlog. Because of both the long sales and installation cycles, we may expend significant resources without generating a sale or producing revenue from our bookings and backlog.

These lengthy sales and installation cycles increase the risk that our customers may fail to satisfy their payment obligations, cancel orders before the completion of the transaction or delay the planned date for installation. Cancellation rates may be affected by factors outside of our control including, but not limited to, an inability to install an energy storage system at the customer’s chosen location because of permitting or other regulatory issues, unanticipated changes in the cost or availability of alternative sources of electricity available to the customer or other reasons unique to each customer. Our operating expenses are based on anticipated sales levels, and many of our expenses are fixed. If we are unsuccessful in closing sales after expending significant resources or if we experience delays or cancellations, our business, financial condition and results of operations could be adversely affected.

Additionally, we have ongoing arrangements with our customers and target customers. Some of these arrangements are evidenced by contracts or long-term contract partnership arrangements. If these arrangements are terminated or if we are unable to continue to fulfill the obligations under such contracts or arrangements, our business, financial condition and results of operations could be adversely affected.

If we are unable to attract and retain key employees and hire qualified management, technical, engineering and sales personnel, our ability to compete and successfully grow our business could be adversely affected.

We believe that our success and our ability to reach our strategic objectives are highly dependent on the contributions of our key management, technical, engineering, finance and sales personnel. In 2024, several key executives departed the Company, including our Chief Executive Officer, Chief Financial Officer, Chief Strategy Officer, and Chief Technology Officer. Also, in September 2024, our Board of Directors appointed a new Chief Financial Officer; and in January 2025, a new Chief Executive Officer. Executive leadership and senior management transitions, reductions in workforce and employee turnover can be time-consuming, difficult to manage, create instability, cause disruption to our business and result in the loss of institutional knowledge. Any of these outcomes could impede the execution of our day-to-day operations and our ability to fully implement our business strategy. These effects could also make it more difficult to attract and retain talent. The failure to successfully hire and retain key executives and employees or the further loss of any key executives, senior management and employees could have a significant impact on our operations, including declining product identity and competitive differentiation, eroding employee morale and productivity or an inability to maintain internal controls, regulatory or other compliance related requirements, any and all of which could in turn adversely impact our business, financial condition, and results of operations.

In addition, our ability to manage our growth effectively, including our ability to expand our market presence in international markets, is impacted by our ability to successfully retain our management team, and hire and train new personnels. Our success in hiring, attracting and retaining senior management and other experienced and highly skilled employees will depend in part on our ability to provide competitive compensation packages and a high-quality work environment and maintain a desirable corporate culture. To help attract, retain, and motivate qualified employees, we use stock-based awards, such as restricted stock units, and performance-based cash incentive awards. Further sustained declines in our stock price, or lower stock price performance relative to our competitors, can further reduce the retention value of our stock-based awards. We may

16

not be able to attract, integrate, train, motivate or retain current or additional highly qualified personnel, and our failure to do so could adversely affect our business, financial condition and operating results.

Furthermore, there is continued and increasing competition for talented individuals in our field. In addition to longstanding competition for highly skilled and technical personnel, we face increased competitive pressures and employee cost inflation in tighter labor markets. Industry competition and cross-industry labor market pressures may negatively affect our ability to attract and retain our executive officers and other key technology, sales, marketing and support personnel and drive increases in our employee costs, both of which could adversely affect our business, financial condition and results of operations.

We have incurred significant losses in the past and may incur net losses through at least 2025.

Since our inception in 2009, we have incurred significant net losses and have used significant cash in our business. As of December 31, 2024, we had an accumulated deficit of approximately $1,626.5 million. We expect to continue to expand our operations, including by investing in sales and marketing, research and development, staffing systems and infrastructure to support our growth. In October 2024, we announced a new business strategy, which is expected to result in reduced revenues and short-term disruptions in our operations in the near term. Under our current plans, we expect to continue to incur net losses on a GAAP basis through at least 2025. Our ability to achieve profitability in the future will depend on a number of factors, including:

•executing our new strategy;

•increasing sales to existing customers and attracting new customers for our products and services;

•improving our gross margins;

•growing our sales volume;

•managing operating expenses;

•improving our ability to procure energy storage systems from OEMs on cost-effective terms;

•improving the effectiveness of our sales and marketing activities;

•attracting and retaining key talent in a competitive marketplace;

•operating our systems profitably for the benefit of our customers; and

•the availability of incentives, including those associated with the IRA.

Even if we do achieve profitability when expected, we may be unable to sustain or increase our profitability in the future.

We may not realize expected benefits from our cost reduction and restructuring efforts, and our profitability or our business otherwise might be adversely affected.

In order to operate more efficiently and cost effectively, we have, and we may from time to time, adjust employment levels, optimize our footprint and/or implement other restructuring activities. These activities are complex and may involve or require significant changes to our operations. If we do not successfully manage these activities, expected efficiencies and benefits might be delayed or not realized. Risks associated with these actions and other workforce management issues include: unfavorable political responses and reputational harm; unforeseen delays in the implementation of the restructuring activities; additional costs; adverse effects on employee morale; the failure to meet operational targets due to the loss of employees or work stoppages; and difficulty managing our operations during or after facility consolidations, any of which may impair our ability to achieve anticipated cost reductions, harm our business or reputation, or have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

Any future acquisitions we undertake may disrupt our business, adversely affect operations, dilute our stockholders, and expose us to significant costs and liabilities.

We may pursue future acquisitions to increase revenue, expand our market position, add to our service offerings and technological capabilities, respond to dynamic market conditions, or for other strategic or financial purposes. However, we cannot assure you that we will be able to identify suitable acquisition candidates or complete any acquisitions on favorable terms, or at all. In addition, any acquisitions we do complete would involve a number of risks, which may include the following:

•the identification, acquisition and integration of acquired businesses require substantial attention from management. The diversion of management’s attention and any difficulties encountered in the integration process could hurt our business;

17

•the identification, acquisition and integration of acquired businesses requires significant investment, including to determine which new service offerings we might wish to acquire, harmonize service offerings, expand management capabilities and market presence, and improve or increase development efforts and technology features and functions;

•the anticipated benefits from any acquisition may not be achieved on a timely basis or at all, including as a result of loss of clients or personnel of the target, other difficulties in supporting and transitioning the target's clients, difficulties in managing expanded operations and operations in foreign jurisdictions in which we have never operated, the inability to realize expected synergies from an acquisition, or negative organizational cultural effects arising from the integration of new personnel;

•we may face difficulties in integrating the personnel, technologies, solutions, operations, and existing contracts of the acquired business;

•we may fail to identify all of the problems, liabilities, risks or other shortcomings or challenges of an acquired company, technology or solution, including issues related to intellectual property, solution quality or architecture, income tax and other regulatory compliance practices, revenue recognition or other accounting or internal control practices, or employee or client issues;

•to pay for future acquisitions, we could issue additional shares of our common stock or pay cash. Issuance of shares would dilute stockholders. See “- We may issue a significant number of shares in the future in connection with investments or acquisitions” below. Use of cash reserves could diminish our ability to respond to other opportunities or challenges. Borrowing to fund any cash purchase price would result in increased fixed obligations and could also include covenants or other restrictions that would impair our ability to manage our operations;

•acquisitions expose us to the risk of assumed known and unknown liabilities including contract, tax, regulatory or other legal, and other obligations incurred by the acquired business or fines or penalties, for which indemnity obligations, escrow arrangements or insurance may not be available or may not be sufficient to provide coverage;

•new business acquisitions can generate significant intangible assets that result in substantial related amortization charges and the potential for goodwill impairments in the future;

•the operations of acquired businesses, or our adaptation of those operations, may require that we apply revenue recognition or other accounting methodologies, assumptions, and estimates that are different from those we use in our current business, which could complicate our financial statements, expose us to additional accounting and audit costs, and increase the risk of accounting errors;

•acquired businesses may have insufficient internal controls that we must remediate, and the integration of acquired businesses may require us to modify or enhance our own internal controls, in each case resulting in increased administrative expense and risk that we experience control deficiencies or fail to comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002; and

•acquisitions can sometimes lead to disputes with the former owners of the acquired company, which can result in increased legal expenses, management distraction and the risk that we may suffer an adverse judgment if we are not the prevailing party in the dispute.

Our current and planned foreign operations expose us to additional business, financial, regulatory and geopolitical risks, and any adverse event could have a material adverse effect on our results of operations.

We operate in more than 50 countries, including the United States and Canada, and in multiple European Union (“EU”) and Latin American countries and Asia. Prior to our acquisition of AlsoEnergy in 2022, we operated in only three countries. We have in the past, and may in the future, evaluate further opportunities to expand into new geographic markets and introduce new product offerings and services that are an extension of our existing business. We also may from time to time acquire businesses or product lines with the potential to strengthen our market position, enable us to enter attractive markets, expand our technological capabilities, or provide synergy opportunities.

We have very limited experience operating outside of the U.S. Managing our international expansion will require additional resources and controls, including additional manufacturing and assembly facilities. Furthermore, any additional markets that we may enter could have different characteristics from the markets in which we currently operate, and our success will depend on our ability to adapt properly to these differences. Any further international expansion could subject our business to risks associated with international operations, including:

•compliance with multiple, potentially conflicting and changing governmental laws, regulations and permitting processes, including trade, labor, environmental, banking, employment, privacy and data protection laws and

18

regulations, such as the EU Data Privacy Directive, as well as tariffs, export quotas, customs duties and other trade restrictions;

•compliance with U.S. and foreign anti-bribery laws, including the Foreign Corrupt Practices Act of 1977, as amended;

•difficulties in collecting payments in foreign currencies and associated foreign currency exposure;

•compliance with potentially conflicting and changing laws of taxing jurisdictions where we conduct business and applicable U.S. tax laws as they relate to international operations, the complexity and adverse consequences of such tax laws and potentially adverse tax consequences due to changes in such tax laws;

•the laws of some countries do not protect proprietary rights as fully as do the laws of the U.S. As a result, we may not be able to protect our proprietary rights adequately outside of the U.S.;

•regional macroeconomic and geopolitical conditions;

•conformity with applicable business customs, including translation into foreign languages and associated expenses;

•lack of availability of government incentives and subsidies;

•potential changes to our established business model;

•cost of alternative power sources, which could vary meaningfully outside the U.S.;

•difficulties in staffing and managing foreign operations in an environment of diverse culture, laws and customers, and the increased travel, infrastructure and legal and compliance costs associated with international operations;

•customer installation challenges which we have not encountered before, which may require the development of a unique model for each country;

•differing levels of demand among members of our customer base, including commercial and industrial customers, utilities, independent power producers and project developers; and

•restrictions on repatriation of earnings.

As a result of these risks, any future international expansion efforts that we may undertake (as well as our acquisition of AlsoEnergy) may not be successful and may negatively affect our results of operations and profitability.

In addition, there may be adverse effects to our business if there is instability, disruption or destruction in a significant geographic region, regardless of cause, including war, terrorism, riot, civil insurrection or social unrest; and natural or man-made disasters, including famine, flood, fire, earthquake, storm or disease. The U.S. government and other governments in jurisdictions in which we operate have imposed severe sanctions and export controls against Russia and Russian interests, and have threatened additional sanctions and controls. The ongoing conflict between Russia and Ukraine has exacerbated shortages and shipping delays affecting certain components and supplies. It is not possible to predict the broader consequences of this conflict, which could include further sanctions, embargoes, greater regional instability, geopolitical shifts and other adverse effects on macroeconomic conditions, international trade, currency exchange rates, supply chains and financial markets.

Our platform performance may not meet our customers’ expectations or needs.

The renewable energy projects that our customers construct and own 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 or our operators’, customers’ or utilities’ equipment; an inability to find suitable replacement equipment or parts; lower than expected supply or quality of the project’s source of electricity or faster than expected diminishment of such electricity supply; or volume disruption in our supply collection and distribution system. Any extended interruption or failure of our customer’s projects for any reason to generate the expected amount of output could adversely affect our business, financial condition and results of operations. In addition, there has been in the past, and may be in the future, an adverse impact on our customers’ willingness to continue to procure additional hardware and software-enabled services from us if any of our customer’s projects incur operational issues that indicate expected future cash flows from the project are less than the project’s carrying value. Any such outcome could adversely affect our operating results or ability to continue to grow our sales volume or to increase sales to existing customers or new customers.

19

If any energy storage systems procured from OEM suppliers and provided to our customers contain manufacturing defects, our business and financial results could be adversely affected.

The energy storage systems we pair with our Athena® platform are complex energy solutions. We rely on our OEM suppliers to control the quality of the battery storage equipment and other components that make up the energy storage system sold to our customers. We are not involved in the manufacture of the batteries or other components of the energy storage systems. As a result, our ability to seek recourse for liabilities and recover costs from our OEM suppliers depends on our contractual rights as well as the financial condition and integrity of such OEM suppliers that supply us with the batteries and other components of our energy storage systems. Such systems may contain undetected or latent errors or defects. In the past, we have discovered latent defects in energy storage systems. In connection with such defects, we could incur significant expenses or disruptions of our operations, including to our energy storage network, that would prevent us from performing the automated data engineering required to support our AI processes and energy storage network. Any manufacturing defects or other failures of our energy storage systems to perform as expected could cause us to incur significant re-engineering costs, divert the attention of our personnel from operating and maintenance efforts, expose us to adverse regulatory action and litigation and significantly and adversely affect customer satisfaction, market acceptance and our business reputation. Furthermore, our OEM suppliers may be unable to correct manufacturing defects or other failures of any energy storage systems in a manner satisfactory to our customers, which could adversely affect customer satisfaction, market acceptance and our business reputation.

On rare occasions, lithium-ion batteries can rapidly release the energy they contain by venting smoke and flames in a manner that can ignite nearby materials as well as other lithium-ion batteries. Any such occurrences could subject us to lawsuits, product recalls or redesign efforts, all of which would be time consuming and expensive. Also, negative public perceptions regarding the suitability of lithium-ion batteries for energy applications or any future incident involving lithium-ion batteries, such as a plant, vehicle or other fire, even if such incident does not involve hardware provided by us, could adversely affect our business and reputation.

If our estimates of useful life for our energy storage systems and related hardware and software-enabled services are inaccurate, or if our OEM suppliers do not meet service and performance warranties and guarantees, our business and financial results could be adversely affected.

Our software and services offerings are essential to the operation of our hardware products that we sell to customers. As a result, in connection with the sales of energy storage hardware, we enter into recurring long-term services agreements with customers for the usage of our Athena platform for approximately 3 to 20 years. Our pricing of services contracts is based upon the value we expect to deliver to our customers, including considerations such as the useful life of the energy storage system and prevailing electricity prices. We also provide performance warranties and guarantees covering the efficiency and output performance of our software-enabled services. We do not have a long history with a large number of field deployments, and our estimates may prove to be incorrect. Failure to meet these performance warranties and guarantee levels may require us to refund our service contract payments to the customer, or require us to make cash payments to the customer based on actual performance, as compared to expected performance.

Further, the occurrence of any defects, errors, disruptions in service, or other performance problems, interruptions, or delays associated with our energy storage systems or the Athena platform, whether in connection with day-to-day operations or otherwise, could result in:

•loss of customers;

•loss or delayed market acceptance and sales of our hardware and software-enabled services;

•delays in payment to us by customers;

•injury to our reputation and brand;

•legal claims, including warranty and service level agreement claims, against us; or

•diversion of our resources, including through increased service and warranty expenses or financial concessions, and increased insurance costs.

The costs incurred in correcting any material defects or errors in our hardware and software or other performance problems may be substantial and could adversely affect our business, financial condition and results of operations.

20

The failure of renewable energy hardware costs to continue to decline would have a negative effect on our business and financial condition.

The growth and profitability of our business depends in part on the continued decline in the cost of battery storage, solar photovoltaic (“PV”) system components and related hardware. Over the last decade, the cost of renewable energy hardware has generally declined; however, increased demand and global supply chain constraints could cause price increases. If, for whatever reason, there is a sustained increase in the price of battery storage systems, solar PV system components or related hardware, our business and financial condition will be negatively affected.

Future product recalls could materially adversely affect our business, financial condition and operating results.

Any product recall in the future, whether it involves our or a competitor’s product, may result in negative publicity, damage our brand and materially and adversely affect our business, financial condition and results of operations. In the future, we may voluntarily or involuntarily initiate a recall if any of our products are proven to be or possibly could be defective or noncompliant with applicable environmental laws and regulations, including health and safety standards. Such recalls involve significant expense and diversion of management attention and other resources, which could adversely affect our brand image, as well as our business, financial condition and operating results.

We primarily rely on Amazon Web Services to deliver our services to users on our Athena platform, and any disruption of, or interference with, our use of Amazon Web Services could adversely affect our business, financial condition and results of operations.

We currently host our Athena platform and support our energy storage network operations on one or more data centers provided by Amazon Web Services (“AWS”), a third-party provider of cloud infrastructure services. We do not have control over the operations of the facilities of AWS that we use. AWS’ facilities are vulnerable to damage or interruption from natural disasters, cybersecurity attacks, terrorist attacks, power outages, and similar events or acts of misconduct.

Our Athena platform’s continuing and uninterrupted performance is critical to our success. We have experienced, and expect that in the future we will experience, interruptions, delays, and outages in service and availability from time to time due to a variety of factors, including infrastructure changes, human or software errors, website hosting disruptions and capacity constraints. In addition, any changes in AWS’ service levels may adversely affect our ability to meet the requirements of users on our Athena platform. Since our Athena platform’s continuing and uninterrupted performance is critical to our success, sustained or repeated system failures would reduce the attractiveness of our hardware and software-enabled services to customers. It may become increasingly difficult to maintain and improve our performance, as we expand and our energy storage network grows, increasing customer reliance on the Athena platform. Any negative publicity arising from any disruptions to AWS’ facilities, and as a result, our Athena platform could adversely affect our reputation and brand and may adversely affect the usage of our hardware and software-enabled services. Any of the above circumstances or events may adversely affect our reputation and brand, reduce the availability or usage of our hardware and software- enabled services, lead to a significant short-term loss of revenue, increase our costs, and impair our ability to attract new users, any of which could adversely affect our business, financial condition and results of operations.

Our commercial agreement with AWS will remain in effect until terminated by AWS or us. AWS may terminate the agreement for convenience by providing us at least thirty (30) days’ advance notice. AWS may also terminate the agreement for cause upon a material breach of the agreement, subject to AWS providing prior written notice and a 30-day cure period, and may in some cases terminate the agreement immediately for cause upon written notice. Even though our platform is entirely in the cloud, we believe that we could transition to one or more alternative cloud infrastructure providers on commercially reasonable terms. If our agreement with AWS is terminated or we add additional cloud infrastructure service providers, we may experience significant costs or downtime for a short period in connection with the transfer to, or the addition of, new cloud infrastructure service providers. However, we do not believe that such transfer to, or the addition of, new cloud infrastructure service providers would adversely affect our business, financial condition and results of operations over the longer term.

Any failure to offer high-quality technical support services may adversely affect our relationships with our customers and adversely affect our financial results.

Our customers depend on our support organization to resolve any technical issues relating to our hardware and software-enabled services. In addition, our sales process is highly dependent on the quality of our software and service offerings, on our business reputation and on strong recommendations from our existing customers. Any failure to maintain high-quality and highly-responsive technical support, or a market perception that we do not maintain high-quality and highly-responsive support, could adversely affect our reputation, our ability to sell our products to existing and prospective customers, and our business, financial condition and results of operations.

21

We offer technical support services with our software and service offerings and may be unable to respond quickly enough to accommodate short-term increases in demand for support services, particularly as we increase the size of our customer base. We also may be unable to modify the format of our support services to compete with changes in support services provided by competitors. It is difficult to predict demand for technical support services and if demand increases significantly, we may be unable to provide satisfactory support services to our customers. Additionally, increased demand for these services, without corresponding revenue, could increase costs and adversely affect our business, financial condition and results of operations.

Our business currently depends on the availability of rebates, tax credits and other financial incentives to our customers. The reduction, modification, or elimination of government economic incentives could cause our revenue to decline and adversely affect business, financial condition and results of operations.

The U.S. federal government and some state and local governments provide incentives to end users and purchasers of our energy storage systems in the form of rebates, tax credits and other financial incentives, such as system performance payments and payments for renewable energy credits associated with renewable energy generation. In addition, some countries outside the United States also provide incentives to current and future end users and purchasers of our energy storage systems. We rely on these governmental rebates, tax credits and other financial incentives to significantly lower the effective price of the hardware and software-enabled services we offer to our customers. However, these incentives may expire on a particular date, end when the allocated funding is exhausted, or be reduced or terminated as a matter of regulatory or legislative policy.

Our asset performance monitoring and control solutions, as well as our energy storage systems, have qualified for tax exemptions, incentives or other customer incentives in many states. Some states have utility procurement programs and/or renewable portfolio standards for which our technology is eligible. Our offerings are currently installed in various U.S. states, each of which may have its own enabling policy framework. There is no guarantee that these policies will continue to exist in their current form, or at all. Such state programs may face increased opposition on the U.S. federal, state and local levels in the future. Changes in incentive programs could reduce demand for our offerings, impair sales financing and adversely impact our business results.

The economic benefit of our offerings to our customers depends on the cost of electricity available from alternative sources, including local electric utility companies, which cost structure is subject to change.

The economic benefit of our offerings to our customers includes, among other things, the benefit of reducing such customer’s payments to the local electric utility company. The rates at which electricity is available from a customer’s local electric utility company is subject to change and any changes in such rates may affect the relative benefits of our products and services. Factors that could influence these rates include the effect of energy conservation initiatives that reduce electricity consumption, construction of additional power generation plants (including nuclear, coal or natural gas), and technological developments by others in the electric power industry. Further, the local electric utility may impose “departing load,” “standby” or other charges on our customers in connection with their acquisition of our energy storage systems, the amounts of which are outside of our control and which may have a material impact on the economic benefit of our energy storage systems to our customers. Changes in the rates offered by local electric utilities and/or in the applicability or amounts of charges and other fees imposed by such utilities on customers acquiring our energy storage systems could adversely affect the demand for our energy storage systems.

Additionally, even with available subsidies for our systems, the electricity produced by our energy storage systems is currently not cost competitive in some geographic markets, and we may be unable to reduce our costs to a level at which our energy storage systems would be competitive in such markets. As such, unless the cost of electricity in these markets rises or we are able to generate demand for our energy storage systems based on benefits other than electricity cost savings, our potential for growth in those markets may be limited.

Our battery resale business is subject to risks associated with construction, utility interconnection and delays, including those related to obtaining government permits and other contingencies that may arise in the course of completing installations.

Although we are not regulated as a utility, federal, state and local government statutes and regulations concerning electricity heavily influence the demand for our products and services. These statutes and regulations often relate to electricity pricing, net metering, incentives, taxation and the rules surrounding the interconnection of customer-owned electricity generation for specific technologies. In the U.S., governments frequently modify these statutes and regulations. Governments, often acting through state utility or public service commissions, may change or adopt different requirements for utilities and rates for commercial customers on a regular basis. Changes, or in some cases a lack of change, in any of the laws, regulations, ordinances or other rules that apply to customer installations and new technology could make it more costly for our customers to install and operate our energy storage systems on particular sites, and in turn could negatively affect our ability to deliver cost savings to customers for the purchase of electricity.

22

The installation and operation of our energy storage systems at a particular site is also generally subject to oversight and regulation in accordance with national, state and local laws and ordinances relating to building codes, safety, environmental protection and related matters, and typically requires obtaining and keeping in good standing various local and other governmental approvals and permits, including environmental approvals and permits, that vary by jurisdiction. In some cases, these approvals and permits require periodic renewal. It is difficult and costly to track the requirements of every individual authority having jurisdiction over energy storage system installations, to design our energy storage systems to comply with these varying standards, and for our customers to obtain all applicable approvals and permits. We cannot predict whether or when all permits required for a given customer’s project will be granted or whether the conditions associated with the permits will be achievable. The denial or delay of a permit or utility connection essential to a project or the imposition of impractical conditions would impair our customer’s ability to develop the project. In addition, we cannot predict whether the permitting process will be lengthened due to complexities and appeals. Delay in the review and permitting process for a project can impair or delay our customers’ abilities to develop that project or increase the cost so substantially that the project is no longer attractive to our customers. Furthermore, unforeseen delays in the review and permitting process could delay the timing of the installation of our energy storage systems and could therefore adversely affect the timing of the recognition of revenue related to hardware acceptance by our customer, which could adversely affect our operating results in a particular period.

In addition, the successful installation of our energy storage systems is dependent upon the availability of and timely connection to the local electric grid. We may be unable to obtain the required consent and authorization of local utilities to ensure successful interconnection to energy grids to enable the successful discharge of renewable energy to customers. Any delays in our customers’ ability to connect with utilities, delays in the performance of installation-related services or poor performance of installation-related services will have an adverse effect on our results and could cause operating results to vary materially from period to period.

Our business depends on customers renewing their services subscriptions. If customers do not continue to use our subscription offerings or if we fail to expand the availability of products and services available to our customers, our business and operating results will be adversely affected.

In addition to upfront sale of hardware and network integration, we depend on customers continuing to subscribe to services enabled by our Athena platform. Therefore, it is important that customers renew their subscriptions when the contract term expires, increase their purchases of our hardware and network solutions and enhance their subscriptions. Customers may decide not to renew their subscriptions with a similar contract period, at the same prices or terms or with the same or a greater number of users or level of functionality. Customer retention may decline or fluctuate as a result of a number of factors, including satisfaction with software-enabled services and features, functionality of our energy storage hardware and software-enabled services, prices, the features and pricing of competing products, reductions in spending levels, mergers and acquisitions involving customers and deteriorating general economic conditions.

If customers do not renew their subscriptions, if they renew on less favorable terms, if they fail to increase their purchase of our hardware and software-enabled services, or if they fail to refer us their customers and partners as potential new customers, our business, financial condition and results of operations will be adversely affected.

Changes in subscriptions or pricing models may not be reflected in near-term operating results.

We generally recognize subscription revenue from customers ratably over the terms of their contracts. As a result, most of the subscription revenue reported in each quarter is derived from the recognition of deferred revenue relating to subscriptions entered into during previous quarters. Consequently, a decline in new or renewed subscriptions in any single quarter will likely have only a small impact on revenue for that quarter. However, such a decline will negatively affect revenue in future quarters. In addition, the severity and duration of events may not be predictable and their effects could extend beyond a single quarter. Accordingly, the effect of significant downturns in sales and market acceptance of subscription services, and potential changes in pricing policies or rate of renewals, may not be fully apparent until future periods.

Severe weather events, including the effects of climate change, are inherently unpredictable and may have a material adverse effect on our financial results and financial condition.

Our business, including our customers and suppliers, may be exposed to severe weather events and natural disasters, such as tornadoes, tsunamis, tropical storms (including hurricanes), earthquakes, windstorms, hailstorms, severe thunderstorms, flooding, wildfires and other fires, extreme heatwaves, drought and power shut-offs causing, among other things, disruptions to our supply chain or utility interconnections and/or damage to energy storage systems installed at our customers’ sites. Such damage or disruptions may prevent us from being able to satisfy our contractual obligations or may reduce demand from our customers for our energy storage systems causing our operating results to vary significantly from one period to the next. We may incur losses in our business in excess of: (1) those experienced in prior years, (2) the average expected level used in pricing, or (3) current insurance coverage limits.

23

The incidence and severity of severe weather conditions and other natural disasters are inherently unpredictable. Climate change is projected to affect the occurrence of certain natural events, such as an increase in the frequency or severity of wind and thunderstorm events, and tornado or hailstorm events due to increased convection in the atmosphere; more frequent wildfires and subsequent landslides in certain geographies; higher incidence of deluge flooding; and the potential for an increase in severity of the hurricane events due to higher sea surface temperatures. Changing market dynamics, global policy developments and the increasing frequency and impact of extreme weather events on critical infrastructure in the U.S. and elsewhere as a result of climate change have the potential to disrupt our business, the business of our suppliers and the business of our customers, and may cause us to experience higher attrition, losses and additional costs to maintain or resume operations. Additionally, climate change and the occurrence of severe weather events may adversely impact the demand, price, and availability of insurance. Due to significant variability associated with future changing climate conditions, we are unable to predict the impact climate change will have on our business.

Increased scrutiny from stakeholders and regulators regarding ESG practices and disclosures, including those related to sustainability, and disclosure could result in additional costs and adversely impact our business and reputation.

Companies across all industries are facing increased scrutiny regarding their ESG practices and disclosures and institutional and individual investors are increasingly using ESG screening criteria in making investment decisions. Our disclosures on these matters or a failure to satisfy evolving stakeholder expectations for ESG practices and reporting, which may conflict with one another, may potentially harm our reputation and impact employee retention, customer relationships and access to capital. For example, certain market participants use third-party benchmarks or scores to measure a company’s ESG practices in making investment decisions and customers and supplies may evaluate our ESG practices or require that we adopt certain ESG policies as a condition of awarding contracts. In addition, our failure or perceived failure to pursue or fulfill our goals, targets and objectives or to satisfy various reporting standards within the timelines we announce, or at all, could expose us to government enforcement actions and private litigation. Furthermore, complying or failing to comply with existing or future federal, state, local, and foreign legislation and regulations applicable to our ESG efforts, which may conflict with one another, could cause us to incur additional compliance and operational costs or actions and suffer reputational harm, which could materially and adversely affect our business, financial condition and results of operations.

Our ability to achieve any goal or objective, including with respect to environmental and diversity initiatives and compliance with ESG reporting standards, is subject to numerous risks, many of which are outside of our control. Examples of such risks include the availability and cost of technologies and products that meet sustainability and ethical supply chain standards, evolving regulatory requirements affecting ESG standards or disclosures, our ability to recruit, develop and retain diverse talent in our labor markets, and our ability to develop reporting processes and controls that comply with evolving standards for identifying, measuring and reporting ESG metrics. Methodologies for reporting ESG data may be updated and previously reported ESG data may be adjusted to reflect improvement in availability and quality of third-party data, changes in assumptions, changes in the nature and scope of our operations and other changes in circumstances. Our processes and controls for reporting ESG matters across our operations and supply chain are evolving along with multiple disparate standards for identifying, measuring, and reporting ESG metrics, including ESG-related disclosures that may be required by the SEC, European and other regulators, and such standards may change over time, which could result in significant revisions to our current goals, reported progress in achieving such goals, or ability to achieve such goals in the future. As ESG best-practices, reporting standards and disclosure requirements continue to develop, we may incur increasing costs related to ESG monitoring and reporting.

We Face Risks Related to our DevCo Business Model

In the past, we have entered into strategic joint ventures with qualified third parties to develop energy storage power generation projects (“DevCo Projects”), as more fully described under Note 1 — Business, in the accompanying notes to the consolidated financial statements in Part II, Item 8, “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K. These projects require upfront investment by us and involve a high degree of risk. The success of this business model depends in large part on the successful development, financing and construction of projects. However, such projects ultimately may not be commercially viable or may not result in an adequate return of capital and, in pursuing these projects, we may incur unanticipated liabilities. Successful completion of a project may be adversely affected, delayed or rendered infeasible by numerous factors, including:

•interconnection costs and capacity constraints;

•transmission grid congestion issues;

•delays in obtaining required governmental permits and approvals;

•regulatory changes that adversely affect energy storage participation in wholesale markets;

•changes in wholesale market energy and ancillary services prices and costs;

24

•construction delays and contractor or developer partner performance shortfalls;

•cost overruns, including costs related to renting or owning land necessary to develop DevCo Projects;

•labor, equipment, and material supply shortages, failures or disruptions; and

•force majeure and other events out of our control.

In addition, our joint venture partners may at any time have economic, business or legal interests or goals that are inconsistent with the goals of the DevCo Project. Disagreements with our business partners may impede our ability to recognize the benefits of our DevCo Projects. Our joint venture partners may be unable or unwilling to meet their performance or other obligations under the operative documents, and we may be required to fulfill those obligations or to dissolve and liquidate the DevCo Project.

If a DevCo Project experiences any of the factors listed above or otherwise fails to reach completion or is significantly delayed, we could lose all or a portion of our development capital investment. If a DevCo Project fails then we may be unable to recover our investment. Losing or delaying return of all or a portion of our investments in our DevCo Projects could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to Third-Party Partners

Our hardware and certain of our software-enabled services rely on interconnections to distribution and transmission facilities that are owned and operated by third parties, and as a result, are exposed to interconnection and transmission facility development and curtailment risks.

Our hardware and certain of our software-enabled services are interconnected with electric distribution and transmission facilities owned and operated by regulated utilities necessary to deliver the electricity that our storage systems produce. A failure or delay in the operation or development of these distribution or transmission facilities could result in a loss of revenues or breach of a contract because such a failure or delay could limit the amount of renewable electricity that our energy storage systems deliver or delay the completion of our customers’ construction projects. In addition, certain of our energy storage systems’ generation may be curtailed without compensation due to distribution and transmission limitations, reducing our revenues and impairing our ability to capitalize fully on a particular customer project’s potential. Such a failure or curtailment at levels above our expectations could impact our ability to satisfy agreements entered into with our suppliers and adversely affect our business.

Our growth depends in part on the success of our relationships with third parties, including contractors and project developers

We rely on third-party general contractors to install energy storage systems at our customers’ sites. We currently work with a limited number of general contractors, which has impacted and may continue to impact, our ability to facilitate customer installations as planned. Our work with contractors or their subcontractors may have the effect of our being required to comply with additional rules (including rules unique to our customers), working conditions, site remediation and other union requirements, which can add costs and complexity to an installation project. The timeliness, thoroughness and quality of the installation-related services performed by our general contractors and their subcontractors in the past have not always met our expectations or standards, and in the future may not meet our expectations and standards. It may be difficult to find and train third-party general contractors that meet our standards at a competitive cost.

In addition, we are investing resources in establishing strategic relationships with market players across a variety of industries, including large renewable project developers, to generate new customers. These programs may not roll out as quickly as planned or produce the results we anticipated. A significant portion of our business depends on attracting new partners and retaining existing partners. Negotiating relationships with our partners, investing in due diligence efforts with potential partners, training such third parties and contractors and monitoring them for compliance with our standards require significant time and resources and may present greater risks and challenges than expanding a direct sales or installation team. If we are not successful in establishing or maintaining our relationships with these third parties, our ability to grow our business and address our market opportunity could be impaired. Even if we are able to establish and maintain these relationships, we may not be able to execute on our goal of leveraging these relationships to meaningfully expand our business, brand estimates of variable consideration related to revenue recognition, and customer base. Such circumstances would limit our growth potential and our opportunities to generate significant additional revenue or cash flows.

25

We must maintain customer confidence in our long-term business prospects in order to maintain and grow our business.

Customers may be less likely to purchase our products and services if they do not believe that our business will succeed or that our services and support and other operations will continue in the long term. Similarly, suppliers and other third parties will be less likely to invest time and resources in developing business relationships with us if they do not believe that our business will succeed. Accordingly, in order to build and maintain our business, we must maintain confidence among customers, suppliers, analysts, ratings agencies and other parties in our products and services, long-term financial viability and business prospects. Maintaining such confidence may be particularly complicated by certain factors including those that are largely outside of our control, such as our decline in our stock price, the potential delisting of our common stock on the New York Stock Exchange, changes in senior management, recent change in business strategy, customer unfamiliarity with our products and services, delivery and service operations to meet demand, competition, future changes in the evolving distributed and renewable energy markets or uncertainty regarding sales performance compared with market expectations.

Accordingly, in order to grow our business, we must maintain confidence among our customers, OEM suppliers, third-party general contractor partners, financing partners and other parties in our long-term business prospects. This may be particularly complicated by factors such as:

•our recent change in business strategy;

•our limited operating history at current scale;

•our historical and current lack of profitability;

•unfamiliarity with or uncertainty about our energy storage systems and the overall perception of the distributed and renewable energy generation markets;

•prices for electricity in particular markets;

•competition from alternate sources of energy;

•warranty or unanticipated service issues we may experience in connection with third-party manufactured hardware and our proprietary software;

•the environmental consciousness and perceived value of environmental programs to our customers;

•the size of our expansion plans in comparison to our existing capital base and the scope and history of operations; and

•the availability and amount of incentives, credits, subsidies or other programs to promote installation of energy storage systems.

Several of these factors are largely outside our control, and any negative perceptions about our long-term business prospects, even if unfounded, would likely adversely affect our business, financial condition and results of operations.

Risks Related to Our Intellectual Property and Technology

If we are unsuccessful in developing and maintaining our proprietary technology, our ability to attract and retain partners could be impaired, our competitive position could be adversely affected and our revenue could be reduced.

Our future growth depends on our ability to continue to develop and maintain our proprietary technology that supports our products and software-enabled services, including our Athena platform. In the event that our current or future products and services require features that we have not developed or licensed, or we lose the benefit of an existing license, we will be required to develop or obtain such technology through purchase, license or other arrangements. If the required technology is not available on commercially reasonable terms, or at all, we may incur additional expenses in an effort to internally develop the required technology. We have received patents and have filed patent applications with respect to certain aspects of our technology, and we generally rely on patent protection with respect to our proprietary technology, as well as a combination of trade secrets and copyright law, employee and third-party non-disclosure agreements and other protective measures to protect intellectual property rights pertaining to our proprietary technology and hardware and software- enabled services. There can be no assurance that the steps taken by us to protect any of our proprietary technology will be adequate to prevent misappropriation of these technologies by third parties. If we were unable to maintain our existing proprietary technology, our ability to attract and retain customers could be impaired, our competitive position could be adversely affected, and our revenue could be reduced.

26

A failure of our information technology (“IT”) and data security infrastructure could adversely affect our business and operations.

The efficient operation of our business depends on our IT systems, some of which are managed by third-party service providers. We rely upon the capacity, reliability and security of our IT and data security infrastructure and our ability to effectively manage our business data, accounting, financial, legal and compliance functions, communications, supply chain, order entry and fulfillment, and expand and routinely update this infrastructure in response to the changing needs of our business. Our existing IT systems and any new IT systems we utilize may not perform as expected. If we experience a problem with the functioning of an important IT system or a security breach of our IT systems, including during system upgrades or new system implementations, the resulting disruptions could adversely affect our business.

Despite our implementation of reasonable security measures, our IT systems, like those of other companies, are vulnerable to damages from computer viruses, natural disasters, fire, power loss, telecommunications failures, personnel misconduct, human error, unauthorized access, physical or electronic security breaches, cyber-attacks (including malicious and destructive code, phishing attacks, ransomware, and denial of service attacks), and other similar disruptions. Such attacks or security breaches may be perpetrated by bad actors internally or externally (including computer hackers, persons involved with organized crime, or foreign state or foreign state-supported actors). Cybersecurity threat actors employ a wide variety of methods and techniques that are constantly evolving, increasingly sophisticated, and difficult to detect and successfully defend against. Moreover, we may not have the current capability to detect certain vulnerabilities, which may allow those vulnerabilities to persist in our systems over long periods of time. Additionally, it may take considerable time for us to investigate and evaluate the full impact of incidents, particularly for sophisticated attacks. These factors may inhibit our ability to provide prompt, full, and reliable information about the incident to our customers, partners, regulators, and the public. Geopolitical tensions or conflicts, such as Russia’s invasion of Ukraine, may further heighten the risk of cyber-attacks. The emergence and maturation of AI capabilities may also lead to new and/or more sophisticated methods of attack, including fraud that relies upon “deep fake” impersonation technology or other forms of generative automation that may scale up the efficiency or effectiveness of cyber-attacks. We have experienced such incidents in the past, and any future incidents could expose us to claims, litigation, regulatory or other governmental investigations, administrative fines and potential liability. Any system failure, accident or security breach could result in disruptions to our operations. A material network breach in the security of our or our service providers’ IT systems could include the theft of our trade secrets, customer information, human resources information or other confidential data, including but not limited to personally identifiable information. Although past incidents have not had a material adverse effect on our business operations or financial performance, to the extent that any disruptions or security breach results in a loss or damage to our data, or an inappropriate disclosure of confidential, proprietary or customer information, it could cause significant damage to our reputation, affect our relationships with our customers and strategic partners, lead to claims against us from governments and private plaintiffs, and otherwise adversely affect our business. We cannot guarantee that future cyberattacks, if successful, will not have a material effect on our business or financial results.

Many governments have enacted laws requiring companies to provide notice of cyber incidents involving certain types of data, including personal data. If an actual or perceived cybersecurity breach of security measures, unauthorized access to our system or the systems of the third-party vendors that we rely upon, or any other cybersecurity threat occurs, we may incur liability, costs, or damages, contract termination, our reputation may be compromised, our ability to attract new customers could be negatively affected, and our business, financial condition, and results of operations could be materially and adversely affected. Any compromise of our security could also result in a violation of applicable domestic and foreign security, privacy or data protection, consumer and other laws, regulatory or other governmental investigations, enforcement actions, and legal and financial exposure, including potential contractual liability. In addition, we may be required to incur significant costs to protect against and remediate damage caused by these disruptions or security breaches in the future. While we carry cyber insurance, we cannot be certain that our coverage will be adequate for liabilities actually incurred, that insurance will continue to be available to us on commercially reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim.

Our technology could have undetected defects, errors or bugs in hardware or software which could reduce market adoption, damage our reputation with current or prospective customers and/or expose us to product liability and other claims that could materially and adversely affect our business.

We may be subject to claims that our product and service offerings, including the Athena platform, have malfunctioned and persons were injured or purported to be injured. Any insurance that we carry may not be sufficient or it may not apply to all situations. Similarly, to the extent that such malfunctions are related to components obtained from third-party vendors, such vendors may not assume responsibility for such malfunctions. In addition, our customers could be subjected to claims as a result of such incidents and may bring legal claims against us to attempt to hold us liable. Any of these events could adversely affect our brand, relationships with customers, operating results or financial condition.

Furthermore, our Athena platform is complex, developed for over a decade by many developers, and includes a number of licensed third-party commercial and open-source software libraries. Our software has contained defects and errors and may in

27

the future contain undetected defects or errors. We continue to evolve the features and functionality of our platform through updates and enhancements, and as we do, we may introduce additional defects or errors that may not be detected until after deployment to customers through our hardware. In addition, if our hardware and software-enabled services, including any updates or patches, are not implemented or used correctly or as intended, inadequate performance and disruptions in service may result.

Any defects or errors in product or services offerings, or the perception of such defects or errors, or other performance problems could result in any of the following, each of which could adversely affect our business, financial condition and results of operations:

•expenditure of significant financial and product development resources, including recalls, in efforts to analyze, correct, eliminate or work around errors or defects;

•loss of existing or potential customers or partners;

•interruptions or delays in sales;

•delayed or lost revenue;

•delay or failure to attain market acceptance;

•delay in the development or release of new functionality or improvements;

•negative publicity and reputational harm;

•sales credits or refunds;

•exposure of confidential or proprietary information;

•diversion of development and customer service resources;

•breach of warranty claims;

•legal claims under applicable laws, rules and regulations; and

•the expense and risk of litigation.

Although we have contractual protections, such as warranty disclaimers and limitation of liability provisions, in many of our agreements with customers, resellers and other business partners, such protections may not be uniformly implemented in all guarantees that we have issued under certain customer contracts and, where implemented, may not fully or effectively protect from claims by customers, resellers, business partners or other third parties. Any insurance coverage or indemnification obligations of suppliers may not adequately cover all such claims, or cover only a portion of such claims. A successful product liability, warranty, or other similar claim could have an adverse effect on our business, financial condition and operating results. In addition, even claims that ultimately are unsuccessful could result in expenditure of funds in litigation, divert management’s time and other resources and cause reputational harm.

Our failure to adequately secure, protect and enforce our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly.

Although we have taken many protective measures to protect our intellectual property, including trade secrets, policing unauthorized use of proprietary technology can be difficult and expensive. For example, many of our software developers reside in California and we cannot legally prevent them from working for a competitor.

Also, litigation may be necessary to enforce our intellectual property rights, protect our trade secrets, or determine the validity and scope of the proprietary rights of others. Such litigation may result in our intellectual property rights being challenged, limited in scope or declared invalid or unenforceable. We cannot be certain that the outcome of any litigation will be in our favor, and an adverse determination in any such litigation could impair our intellectual property rights and may adversely affect our business, prospects and reputation.

We rely primarily on patent, trade secret and trademark laws, and non-disclosure, confidentiality, and other types of contractual restrictions to establish, maintain, and enforce our intellectual property and proprietary rights. However, our rights under these laws and agreements afford us only limited protection and the actions we take to establish, maintain, and enforce our intellectual property rights may not be adequate. For example, our trade secrets and other confidential information could be disclosed in an unauthorized manner to third parties, our owned or licensed intellectual property rights could be challenged, invalidated, circumvented, infringed, or misappropriated or our intellectual property rights may not be sufficient to provide us with a competitive advantage, any of which could have a material adverse effect on our business, financial condition and results

28

of operations. Additionally, we rely on our brand names, trade names and trademarks to distinguish our products and services, such as our Athena® platform, from the products of our competitors; however, third parties may oppose our trademark applications, or otherwise challenge our use of such trademarks. In the event that our trademarks are successfully challenged and we lose rights to use those trademarks, we could be forced to rebrand our products and services, which could result in the loss of goodwill and brand recognition. In addition, the laws of some countries do not protect proprietary rights as fully as do the laws of the U.S. As a result, we may not be able to protect our proprietary rights adequately abroad.

Our patent applications may not result in issued patents, and our issued patents may not provide adequate protection, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours.

We cannot be certain that our pending patent applications will result in issued patents or that any of our issued patents will afford protection against a competitor. The status of patents involves complex legal and factual questions, and the breadth of claims allowed is uncertain. As a result, we cannot be certain that the patent applications that we file will result in patents being issued, or that our patents and any patents that may be issued to us in the future will afford protection against competitors with similar technology. In addition, patent applications filed in foreign countries are subject to laws, rules and procedures that differ from those of the U.S., and thus we cannot be certain that foreign patent applications related to issued U.S. patents will be issued in other regions. Furthermore, even if these patent applications are accepted and the associated patents issued, some foreign countries provide significantly less effective patent enforcement than in the U.S.

In addition, patents issued to us may be infringed upon or designed around by others and others may obtain patents that we need to license or design around, either of which would increase costs and may adversely affect our business, prospects, and operating results.

We may need to defend ourselves against claims that we infringe, have misappropriated or otherwise violate the intellectual property rights of others, which may be time consuming and would cause us to incur substantial costs.

Companies, organizations, or individuals, including our competitors, may hold or obtain patents, trademarks, or other proprietary rights that they may in the future believe are infringed by our products and services. Although we are not currently subject to any claims related to intellectual property, these companies holding patents or other intellectual property rights allegedly relating to our technologies could, in the future, make claims or bring suits alleging infringement, misappropriation or other violations of such rights, or otherwise asserting their rights and seeking licenses or injunctions. Several of the proprietary components used in our energy storage systems have been subjected to infringement challenges in the past. We also generally indemnify our customers against claims that the hardware and software-enabled services we supply infringe, misappropriate, or otherwise violate third-party intellectual property rights, and we may therefore be required to defend our customers against such claims. If a claim is successfully brought in the future and we or our hardware and software-enabled services are determined to have infringed, misappropriated, or otherwise violated a third-party’s intellectual property rights, we may be required to do one or more of the following:

•cease selling products or services that incorporate the challenged intellectual property;

•pay substantial damages (including treble damages and attorneys’ fees if our infringement is determined to be willful);

•obtain a license from the holder of the intellectual property right, which license may not be available on reasonable terms or at all; or

•redesign our products or services, which may not be possible or cost-effective.

Any of the foregoing could adversely affect our business, financial condition and operating results. In addition, any litigation or claims, whether or not valid, could adversely affect our reputation, result in substantial costs, and divert resources and management attention.

We also license technology from third parties, and incorporate components supplied by third parties into our hardware. We may face claims that our use of such technology or components infringes or otherwise violates the rights of others, which would subject us to the risks described above. We may seek indemnification from our licensors or suppliers under our contracts with them, but our rights to indemnification or our suppliers’ resources may be unavailable or insufficient to cover our costs and losses.

Regulatory Risks

Negative attitudes toward renewable energy projects from the U.S. government, other lawmakers and regulators, and activists could adversely affect our business, financial condition and results of operations.

Parties with an interest in other energy sources, including lawmakers, regulators, policymakers, environmental and advocacy organizations or other activists may invest significant time and money in efforts to delay, repeal or otherwise negatively influence laws, regulations and programs that promote renewable energy. Many of these parties have substantially greater resources and influence than we have. Further, changes in U.S. federal, state or local political, social or economic conditions, including the recent change in U.S. Presidential administration or deprioritization of these laws, programs and regulations, could result in their modification, delayed adoption or repeal. Any failure to adopt, delay in implementing, expiration, repeal or modification of these programs and regulations, or the adoption of any programs or regulations that encourage the use of other energy sources over renewable energy, could adversely affect our business, financial condition and results of operations.

The installation and operation of our energy storage systems are subject to environmental laws and regulations in various jurisdictions, and there is uncertainty with respect to the interpretation of certain environmental laws and regulations to our energy storage systems, especially as these regulations evolve over time.

We are subject to national, state and local environmental laws and regulations, as well as environmental laws in those foreign jurisdictions in which we operate. Environmental laws and regulations can be complex and are evolving. These laws can give rise to liability for administrative oversight costs, cleanup costs, property damage, bodily injury, fines and penalties. We are committed to compliance with applicable environmental laws and regulations, including health and safety standards, and we routinely review the operation of our energy storage systems for health, safety and compliance. Our energy storage systems, like other battery technology-based products of which we are aware, produce small amounts of hazardous wastes and air pollutants, and we seek to handle these materials in accordance with applicable regulatory standards.

Maintaining compliance with laws and regulations can be challenging given the changing patchwork of environmental laws and regulations that prevail at the U.S. federal, state, regional and local levels and in foreign countries in which we operate. Most existing environmental laws and regulations preceded the introduction of battery technology and were adopted to apply to technologies existing at the time, namely large, coal, oil or gas-fired power plants. Currently, there is generally little guidance from these agencies on how certain environmental laws and regulations may, or may not, be applied to our technology.

In many instances, our technology is moving faster than the development of applicable regulatory frameworks. It is possible that regulators could delay or prevent us from conducting our business in some way pending agreement on, and compliance with, shifting regulatory requirements. Such actions could delay the sale to and installation by customers of energy storage systems, require their modification or replacement, result in fines, or trigger claims of performance warranties and defaults under customer contracts that could require us to refund hardware or service contract payments, any of which could adversely affect our business, financial performance and reputation.

Existing regulations and changes to such regulations impacting the electric power industry may create technical, regulatory and economic barriers which could significantly reduce demand for our energy storage systems.

The market for electricity generation products is heavily influenced by U.S. federal, state, local and foreign government regulations and policies, as well as by tariffs, internal policies and practices of electric utility providers. These regulations, tariffs and policies often relate to electricity pricing and technical interconnection of customer-owned electricity generation. These regulations, tariffs and policies are often modified and could continue to change, and this could result in a significant reduction in demand for our energy storage systems. For example, utility companies commonly charge fees industrial customers for disconnecting from the electric grid or for having the capacity to use power from the electric grid for back-up purposes. These fees could change, increasing the cost to our customers of using our offerings and making them less economically attractive.

30

Opposition to our customers’ project requests for permits or successful challenges or appeals to permits issued for their projects could adversely affect our operating plans.

A decrease in acceptance of renewable energy projects by local populations, an increase in the number of legal challenges, or an unfavorable outcome of such legal challenges could adversely affect the financial condition of our customers and reduce their demand for our hardware and software-enabled services. For example, persons, associations and groups could oppose renewable energy projects in general or our customers’ projects specifically, citing, for example, misuse of water resources, landscape degradation, land use, food scarcity or price increase and harm to the environment. Moreover, regulation may restrict the development of renewable energy plants in certain areas. In order to develop a renewable energy project, our customers are typically required to obtain, among other things, environmental impact permits or other authorizations and building permits, which in turn require environmental impact studies to be undertaken and public hearings and comment periods to be held during which any person, association or group may oppose a project. The effect of such public opposition to renewable energy projects and any resulting reduction in customer demand for our hardware and software-enabled services could adversely affect our business, financial condition and results of operations.

Changes in the U.S. trade environment, including the imposition of import tariffs, could adversely affect the amount or timing of our revenues, results of operations or cash flows.

Escalating trade tensions, particularly between the United States and China, have led to increased tariffs and trade restrictions, including tariffs applicable to certain materials and components for products used in storage or solar energy projects and the renewable energy market more broadly, such as module supply and availability. More specifically, in March 2018, the United States imposed a 25% tariff on steel imports and a 10% tariff on aluminum imports pursuant to Section 232 of the Trade Expansion Act of 1962 and has imposed additional tariffs on steel and aluminum imports pursuant to Section 301 of the Trade Act of 1974. To the extent we source products that contain overseas supplies of steel and aluminum, these tariffs and any additional or increased tariffs could result in interruptions in the supply chain and negatively affect costs and our gross margins. Additionally, in January 2018, the United States adopted a tariff on imported solar modules and cells pursuant to Section 201 of the Trade Act of 1974. The tariff was initially set at 30%, with a gradual reduction over four years to 15%. In 2022, the United States extended the Section 201 solar tariffs for an additional four years, which declines to a rate of 14% in 2025. While this tariff does not apply directly to the components we import, it may indirectly affect us by affecting the financial viability of solar energy projects, which could in turn reduce demand for our products. Furthermore, in July 2018, the United States adopted a 10% tariff on a long list of products imported from China under Section 301 of the Trade Act of 1974, including, inverters and power optimizers, which became effective on September 24, 2018. In June 2019, the Office of the U.S. Trade Representative increased the rate of such tariffs from 10% to 25%. While these tariffs are not directly applicable to our products, they could negatively affect the solar energy projects in which our products are used, which could lead to decreased demand for our products. In 2024, the United States increased Section 301 tariffs on Chinese lithium-ion battery packs from 7.5% to 25%, which are scheduled to take effect in 2026. In 2025, the United States broadly imposed additional 10% tariffs on Chinese goods under the International Emergency Economic Powers Act of 1977.

In addition, the United States currently imposes antidumping and countervailing duties on certain imported crystalline silicon photovoltaic (“PV”) cells and modules from China and Taiwan. Such antidumping and countervailing duties can change over time pursuant to annual reviews conducted by the U.S. Department of Commerce (“USDOC”), and an increase in duty rates could have an adverse impact on our operating results.
