We have only been in existence since January 3, 2017 and the first installation of Voyager was in the third quarter of 2019. Our solar tracker systems and other solar energy products and services are used primarily in utility-scale ground-mounted solar energy projects. As a result, our future success depends on continued demand for utility-scale solar energy products and services and the ability of solar equipment manufacturers and suppliers to meet this demand. The solar industry is an evolving industry that has experienced substantial changes in recent years, and consumers and businesses ultimately may not adopt solar energy as an alternative energy source at levels sufficient to grow our business. Some of the factors that may impact the demand for solar energy include:

We have encountered and will continue to encounter risks and difficulties frequently experienced by growing companies in rapidly changing industries, including unpredictable and volatile revenue. If demand for solar energy fails to develop sufficiently or is not sustained, demand for our products and services will suffer, which would have an adverse impact on our ability to increase our revenue and grow our business.

We had net loss of $15.9 million for the year ended December 31, 2020, we have incurred substantial net losses from our inception through the year ended December 31, 2019, and we may not be able to achieve profitability and may incur additional losses in the future. At December 31, 2020, we had an accumulated deficit of $42.6 million. Our revenue growth may slow or revenue may decline for a number of reasons, including a decline in demand for our offerings, increased competition, a lack of success in converting sales leads into binding purchase orders, loss of existing customers, our inability to sell software and other complementary products, a decrease in the growth of the solar industry or our market share, future decline in average selling prices of our products and services, our inability to enter international markets or our failure to capitalize on growth opportunities. We may not achieve profitability for a number of reasons, including any declines in revenue, as discussed above, as well as increases in costs to manufacture our products, the impact of U.S. trade tariffs and the imposition of additional tariffs applicable to our industry or our products. In addition, we expect to incur additional costs and expenses related to the continued development and expansion of our business, including in connection with any future acquisitions, as well as ongoing development and marketing of our products and services, expanding into new markets and geographies with respect to both manufacturing and sales of our products, maintaining and enhancing our research and development

operations, hiring additional personnel, incurring additional overhead costs and incurring greater costs from professional third party advisors as necessary in connection with the expansion of our business and this offering. We do not know whether our revenue will grow rapidly enough to absorb such costs and expenses, or the extent of such costs and expenses and their impact on our results of operations. If we fail to generate sufficient revenue to support our operations, we may not be able to achieve profitability.

The market for solar energy products and services is highly competitive with relatively low barriers to entry. We principally compete with other solar tracker equipment suppliers, as well as fixed-tilt suppliers. A number of companies have developed or are developing solar tracker systems and other products and services that will compete directly with our products and services in the utility-scale solar energy market. Public competitors in the solar tracker market include, among others, Array Technologies, Inc. and NEXTracker Inc., a subsidiary of Flex Ltd., and there are numerous private company competitors, both domestically and internationally. We expect competition to intensify as new competitors enter the market and existing competitors attempt to increase their market shares. Any failure by us to develop or adopt new or enhanced technologies or processes, or to adapt or react to changes in existing technologies, could result in product obsolescence, the loss of competitiveness of our products, including offering lower cost savings or return on investment relative to competing products, decreased revenue and a loss of market share to competitors.

Several of our existing and potential competitors are significantly larger than we are and may have greater financial, marketing, manufacturing, distribution and customer support resources, as well as broader brand recognition and greater market penetration, especially in certain markets. In addition, our competitors’ existing or future products may result in higher energy production and lower cost of energy for the solar energy projects to which they are deployed, either broadly or in certain conditions. Certain of our competitors offer a more comprehensive set of products, including fixed-tilt systems and one-panel in-portrait tracker systems, which may be attractive to certain customers because they often involve lower up-front costs, whereas we do not. In addition, some of our competitors have more resources and experience in developing or acquiring new products and technologies and creating market awareness for these offerings, as well as more established customer relationships due to their longer operating histories. Since we are a fairly new participant in the solar tracker market, both in the United States and globally, it is essential that we acquire market share from our competitors and our failure to do so could impact our ability to continue to grow our business.

Further, technological advances in the tracker industry are developing rapidly and certain competitors may be able to develop or deploy new products and services more quickly than we can, or that are more reliable or that provide more functionality than ours. For example, we intend to continue to develop and deploy products that can withstand higher windspeeds, are adaptable to irregular site boundaries and undulating terrain and can support larger-format panels, however our competitors may do so more quickly or effectively. In addition, some of our competitors have the financial resources to offer competitive products at aggressive pricing levels, which could cause us to lose sales or market share, or prevent us from gaining sales or market share, or require us to lower prices for our products and services to compete effectively. If we have to reduce our prices, or if we are unable to offset any future reductions in our average selling prices by increasing our sales volume, reducing our costs and expenses or introducing new products and services, our revenue and gross profit would suffer.

We also may face competition from some of our customers or potential customers or other participants in the solar energy industry who evaluate our capabilities against the merits of manufacturing products internally or as a complementary offering to their other products. For example, solar panel manufacturers or project developers could develop or acquire competing technology and, in the case of project developers, use such technology in their solar energy projects. Due to the fact that such customers may not seek to make a profit directly from the manufacture of these products, they may have the ability to manufacture competitive products at a lower cost than we would charge such customers. As a result, our customers or potential customers may purchase fewer of our systems or sell products that compete with our systems, which would negatively impact our revenue and gross profit.

If we fail to achieve broader market acceptance of our products and services, including international acceptance of Voyager, our ability to increase our revenue, gain market share and achieve profitability would be adversely impacted. Our ability to achieve broader market acceptance for our products and services may be affected by a number of factors, including:

In addition, our reputation and our relationship with our customers is paramount to us and we have invested heavily in building a brand and solutions associated with high quality, differentiated product offerings and strong customer service. We believe that maintaining the quality of our products and the strength of our reputation is critical to our existing customer relationships and our ability to win new customers and achieve broader market acceptance. Any negative publicity can adversely affect our reputation, and may arise from many sources, including actual or alleged misconduct, errors or improper business practices by employees, officers or current or former directors, including for activities external to FTC Solar, employee claims against us, product defects or failures, future litigation or regulatory actions, matters affecting our financial reporting or compliance with SEC or exchange listing requirements, media coverage, whether accurate or not, governance lapses or workplace misconduct. For example, two of our directors, who are also founders of our business, held senior management roles, including Chief Executive Officer, at SunEdison Inc. (“SunEdison”) in 2016 at the time SunEdison filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code. One of these directors, Ahmad Chatila, had been one of the defendants in a number of now dismissed federal and state civil actions related to the SunEdison bankruptcy. In addition, we and our officers, directors and/or employees could be involved in future litigation or claims which could result in negative publicity and adversely impact our business, even if without merit. Any such reputational damage could reduce demand for our products, undermine the loyalty of our customers or reduce our ability to attract new customers and recruit and retain employees, and adversely impact our ability to increase our market share and revenue.

Decreases in the price of electricity, whether in organized electric markets or with contract counterparties, may negatively impact the owners of solar energy projects or make the purchase of solar energy systems less economically attractive and would likely result in lower sales of our products and services. The price of electricity could decrease as a result of:

If the cost of electricity generated by solar energy installations incorporating our systems or similar tracker systems is high relative to the cost of electricity from other sources, then our business, financial condition and results of operations may be harmed.

We continue to work on variants of our solar tracker systems that enable direct attachment to solar panels produced by various solar panel manufacturers. The market success of such panel agnostic tracker solutions will depend in part on our ability to continue to work closely with solar panel manufacturers to design solar tracker systems that are compatible with their solar panels, including new larger-format solar panels that are entering the market. The solar panel manufacturer market is large and diversified, with many market participants, and we may not be able to effectively work with all necessary solar panel manufacturers on the development of such compatible tracker solutions for a variety of reasons, including differences in marketing or selling strategy, our relatively limited operating history, competitive considerations, engineering challenges, lack of competitive pricing and technological compatibility. In addition, our ability to form effective partnerships with solar panel manufacturers may be adversely affected by the substantial challenges faced by many of these manufacturers due to declining prices and revenue from sales of solar panels and the tariffs in the United States.

Voyager is new to the market, having achieved product certification and first installation in 2019. While we believe we have quickly built a strong reputation in the industry, resulting in an estimated U.S. tracker market share of approximately 11% as of December 31, 2020, (which was calculated using our MW shipped for fiscal year 2020 compared to a total tracker market shipment estimate from a 2020 Wood Mackenzie report), the limited deployment of Voyager and the short operating history to date for systems that have been installed, coupled with our relatively smaller size and capitalization compared to some of our competitors, could result in lenders or tax equity providers refusing to provide the financing to our customers or their customers that is necessary to purchase solar energy systems based on our product platform on favorable terms, or at all. Additionally, an increase in interest rates, or a reduction in the supply of, or change in the market terms offered for, project debt or tax equity financing, could make it more difficult for our customers or their customers to secure the necessary financing on favorable terms, or at all. Any of these events could result in reduced demand for our products, which could have a material adverse effect on our financial condition and results of operations.

We have been dependent in each year since our inception on a small number of customers who generate a significant portion of our business. For the year ended December 31, 2020, our largest customer accounted for 21% of our revenue and our two largest customers collectively accounted for approximately 40% of our revenue. For the year ended December 31, 2019, our largest customer accounted for 59% of our revenue and our two largest customers collectively accounted for approximately 80% of our revenue. Further, our trade accounts receivable are all from companies within the solar industry, and, as such, we are particularly exposed to industry credit risks.

As a result, we may have difficulty operating profitably if there is a default in payment by any of our customers, we lose an existing order or we are unable to generate new orders from new or existing customers. Furthermore, to the extent that any one customer or a small group of customers continues to account for a large percentage of our revenue, the loss of any such customer or that customer’s inability to meet its payment obligations could materially affect our ability to operate profitably. We anticipate that our dependence on a limited number of customers in any given fiscal year will continue for the foreseeable future. There is always a risk that existing customers will elect not to do business with us in the future or will experience financial difficulties. If we do not book more orders with existing customers, or develop relationships with new customers, we may not be able to increase, or even maintain, our revenue, and our financial condition, results of operations, business and/or prospects may be materially adversely affected.

The commercial contracting and bidding process for solar project development is long and has multiple steps and uncertainties. We closely monitor the development of potential sales leads through this process. Projects leads may not be converted into binding purchase orders at any stage of the bidding process because either (i) a competitors’ product is selected to fulfill some or all of the order due to price, functionality or other reasons or (ii) the project does not progress to the stage involving the purchase of tracker systems. In addition, there is also a risk that an awarded order (which is an order for which we are in the process of documenting a contract but for which a contract has not yet been signed) will not be converted into a binding purchase order. If we fail to convert a significant number of project leads that are subject to our sales and marketing focus (or awarded orders) into binding purchase orders, our business, financial condition or results of operations could be materially adversely affected.

Our quarterly results of operations are difficult to predict and may fluctuate significantly in the future. Because a substantial majority of our sales since inception have been concentrated in the U.S. market, we have experienced seasonal and quarterly fluctuations in the past as a result of seasonal fluctuations in our customers’ businesses. Additionally, our end-users’ ability to install solar energy systems is affected by weather. For example, during the winter months in cold-weather climates in the United States, construction may be delayed in order to let the ground thaw to reduce costs. Such installation delays can impact the timing of orders for our products. We expect expansion into areas with traditionally warmer climates will result in less pronounced seasonal variations in our revenue profile over time. Additionally, we have historically experienced seasonal fluctuations in the purchase patterns of our customers related to the ITC step-downs, with at least some customers placing large orders in the fourth quarter of a particular year and the corresponding shipments occurring during the first half of the subsequent year, resulting in increased revenue in the first half of the year. There are no ITC step-downs in 2021 or 2022, but this fluctuation could continue to impact our business when the ITC step-downs resume after 2022.

Given that we are an early-stage company operating in a rapidly growing industry, the true extent of historic fluctuations due to the seasonality of construction and the ITC step-downs may have been masked by our recent growth rates and consequently may not be readily apparent from our historical results of operations and may be difficult to predict. Any substantial decrease in revenue would have an adverse effect on our financial condition, results of operations, cash flows and stock price. Seasonality and fluctuations in sales as described herein may also present cash flow challenges as well as place strain on our supply chain.

We are currently expanding our operations to other countries, which requires significant resources and management attention and subjects us to regulatory, economic, political and competitive risks in addition to those we already face in the United States. There are significant risks and costs inherent in doing business in international markets, including:

We have limited experience with international regulatory environments and market practices and may not be able to penetrate or successfully operate in the markets we may choose to enter or have entered or otherwise effectively mitigate the regulatory, economic, political, reputational and competitive risks that are inherent when operating in such environments. In addition, we may incur significant expenses as a result of our international expansion, and we may not be successful. Our failure to successfully manage these risks could harm our international operations and have an adverse effect on our business, financial condition and operating results.

In some circumstances, we may decide to grow our business through the acquisition of businesses and technologies rather than through internal development. The identification of suitable acquisition candidates can be difficult, time consuming and costly, and we may not be able to successfully complete identified acquisitions. The risks we face in connection with acquisitions include, but are not limited to:

Our failure to address these risks or other risks encountered in connection with future acquisitions and investments could cause us to fail to realize the anticipated benefits of these acquisitions or investments and incur unanticipated liabilities, or otherwise harm our business. Future acquisitions also could result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities or amortization expenses, any of which could harm our financial condition. Also, the anticipated benefits of any acquisitions may not materialize. Any of these risks, if realized, could materially and adversely affect our business, financial condition and results of operations.

Although we set stringent quality standards for our products, they may contain errors or defects, especially when first introduced or when new generations are released. Errors, defects or poor performance can arise due to design flaws, defects in raw materials or components, manufacturing difficulties and quality control failures, which can affect both the quality and the yield of the product. Any actual or perceived errors, defects or poor performance in our products could result in replacements or recalls, remediation requests, shipment delays, rejection of our products, damage to our reputation, lost revenue, diversion of our engineering personnel from our product development efforts, diversion of our sales personnel from sales efforts and increases in customer service and support costs, all of which could have a material adverse effect on our business, financial condition and results of operations.

Furthermore, defective products may give rise to warranty, indemnity, product liability, liquidated damages or other contractual claims against us that exceed any revenue or profit we receive from the affected products, including claims for damages related to aspects or components of a solar energy project that go beyond the scope of our product offerings. Our limited warranties cover defects in materials and workmanship of our products. As a result, we bear the risk of warranty claims long after we have sold products and recognized revenue. Our accrued reserves for warranty claims are based on our assumptions and we do not have a long history of making such assumptions. As a result, these assumptions could prove to be materially different from the warranty obligations that we may be required to compensate customers for in the case of defective products. Our failure to accurately predict future warranty claims could result in unexpected volatility in, and have a material adverse effect on, our financial condition. In addition, while we seek to support our warranty obligations with warranties from our contract manufacturers, such warranties may not be of the same scope as our warranty obligations, or we may not be able to effectively enforce our rights thereunder.

If one of our products were to cause injury to someone or cause property damage, including as a result of product malfunctions, defects or improper installation, then we could be exposed to product liability claims. We could incur significant costs and liabilities if we are sued and if damages are awarded against us, which could far exceed the revenue we recognize in connection with the related project. Further, any product liability claim we face could be expensive to defend and could divert management’s attention. The successful assertion of a product liability claim against us could result in potentially significant monetary damages, penalties or fines, subject us to adverse publicity, damage our reputation and competitive position and adversely affect sales of our products. In addition, product liability claims, injuries, defects or other problems experienced by other companies in the solar energy industry could lead to unfavorable market conditions for the industry as a whole, and may have an adverse effect on our ability to attract new customers, thus harming our growth and financial performance.

Our future success and ability to implement our business strategy depend, in part, on our ability to attract and retain key personnel, and on the continued contributions of members of our senior management team and key technical personnel, each of whom would be difficult to replace. All of our employees, including our senior management, are free to terminate their employment relationships with us at any time. Competition for highly skilled

individuals with technical expertise is extremely intense in our industry, and we face challenges identifying, hiring and retaining qualified personnel in many areas of our business. Integrating new employees into our team could be disruptive to our operations, require substantial resources and management attention and ultimately prove unsuccessful. An inability to retain our senior management and other key personnel or to attract additional qualified personnel could limit or delay our strategic efforts, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our business has been and could continue to be adversely impacted by the effects of a widespread outbreak of contagious disease, including the recent COVID-19 pandemic. Any widespread outbreak of contagious diseases, or other adverse public health developments, has in the past caused and in the future could cause disruption to, among other things, our contract manufacturers located in the United States and elsewhere around the world, which has in the past caused and in the future could cause delays in our supply chain and product shipments and delays in project completion, as well as reductions in customer support trainings and monitoring of our contract manufacturers, which could adversely affect our business, operations and customer relationships.

To date we have experienced significant supply chain disruptions that have caused delays in product deliveries due to diminished vessel capacity, port detainment of vessels, port congestion, labor shortages and other stresses on cargo infrastructure (including ports, warehouses, trucking and rail transportation), in each case, as a consequence of the COVID-19 pandemic, which have contributed to increased shipping costs and increased lead times for delivery of our tracker systems. We expect that COVID-19-related supply chain challenges will continue for the foreseeable future. Many of our contracts with customers include liquidated damages that are payable for shipment delays, and we have in the past incurred and may in the future incur liabilities under such provisions if we continue to face these challenges.

Additionally, ground operations at project sites have been impacted by health-related restrictions, shelter-in-place orders and worker absenteeism, which resulted in delays in project completion in 2020 and may result in additional delays in the future. Although we are not primarily responsible for the construction or installation process at project sites, any delays due to the COVID-19 pandemic could negatively impact our customer relationships and adversely affect our business. Such restrictions have also hindered our ability to provide on-site support and trainings to our customers and conduct inspections of our contract manufacturers to ensure compliance with approved vendor standards, and may continue to do so in the future.

The macroeconomic effects of the COVID-19 pandemic and the resulting economic downturn may also have the effect of heightening other risks described in this “Risk Factors” section, including those regarding the ability of our customers to raise capital, customer demand and our dependence on timely performance of our manufacturing partners.

The duration and intensity of the impact of the COVID-19 pandemic and resulting disruption to our operations is uncertain and continues to evolve as of the date of this registration statement. Accordingly, management will continue to monitor the impact of the COVID-19 pandemic on our financial condition, cash flows, operations, contract manufacturers, industry, workforce and customer relationships.

Our success partly depends on our ability to protect our intellectual property and other proprietary rights. We rely on a combination of patents, trademarks, copyrights, and trade secrets to establish and protect our intellectual property and other proprietary rights, as well as unfair competition laws, confidentiality and license agreements and other contractual arrangements. As of December 31, 2020, we had six pending patent applications and 45 issued patents in the United States and a total of nine pending patent applications and nine issued patents in jurisdictions outside of the United States including Australia, Canada, China, Germany, India, South Korea and Mexico. Also as of December 31, 2020, we had one registered trademark, for “VOYAGER TRACKER,” and five pending applications to register trademarks in the United States. Our pending patent and trademark applications or other applications for intellectual property registrations may not be approved, issued or granted and our existing and future intellectual property rights may not be valid, enforceable or sufficiently broad to prevent competitors from using technology similar to or the same as our proprietary technology, to prevent our contract manufacturers from providing similar technology to our competitors or to sufficiently allow us to develop and maintain recognized brands. Additionally, our intellectual property rights may afford only limited protection of our intellectual property and may not (i) prevent our competitors or contract manufacturers from duplicating our processes or technology, (ii) prevent our competitors from gaining access to our proprietary information and technology or (iii) permit us to gain or maintain a competitive advantage. Any impairment or other failure to obtain sufficient intellectual property protection could impede our ability to market our products and services, negatively affect our competitive position and harm our business and operating results, including forcing us to, among other things, rebrand or re-design our affected products and services. In countries where we have not applied for patent protection or trademark or other intellectual property registration or where effective patent, trademark, trade secret and other intellectual property laws and judicial systems may not be available to the same extent as in the United States, we may be at greater risk that our proprietary rights will be circumvented, misappropriated, infringed or otherwise violated.

To protect our unregistered intellectual property, including our trade secrets and know-how, we rely in part on trade secret laws and confidentiality and invention assignment agreements with our employees and independent contractors. We also require third parties, such as our customers and contract manufacturers, that may have access to our proprietary technologies and information to enter into non-disclosure agreements or other contracts containing obligations to maintain the confidentiality of our intellectual property. Such measures, however, provide only limited protection, and our confidentiality and non-disclosure agreements and other agreements containing confidentiality provisions may not prevent unauthorized disclosure or use of our confidential information, especially after our employees or third parties end their employment or engagement with us, and may not provide us with an adequate remedy in the event of such disclosure. Furthermore, competitors or other third parties may independently discover our trade secrets, copy or reverse engineer our products or services or portions thereof, or develop similar technology. If we fail to protect our intellectual property and other proprietary rights, or if such intellectual property and proprietary rights are infringed, misappropriated or otherwise violated, our business, results of operations or financial condition could be materially harmed.

Our competitors and other third parties hold numerous patents related to technologies used in our industry, and may hold or obtain patents, copyrights, trademarks or other intellectual property rights that could prevent, limit or interfere with our ability to make, use, develop, sell or market our products and services, which could make it more difficult for us to operate our business. From time to time we may be subject to claims of infringement, misappropriation or other violation of patents or other intellectual property rights or licensing fee and royalty claims and related litigation, and, if we gain greater recognition in the market, we face a higher risk of being the subject of these types of claims. For example, we recently learned that a claim has been filed against us seeking damages for alleged breach of contract and other claims related to a patent license agreement and consulting relationship. See “Our Business – Legal Proceedings”. Regardless of their merit, responding to such claims can be time consuming, can divert management’s attention and resources, and may cause us to incur significant expenses in litigation or settlement. While we believe that our products and services do not infringe in any material respect upon any valid

intellectual property rights of third parties, we may not be successful in defending against any such claims. If we do not successfully defend or settle an intellectual property claim, we could be liable for significant monetary damages and could be prohibited from continuing to use certain technology, business methods, content or brands, could be prohibited from continuing to sell certain products or services, or could be required to license such intellectual property from the applicable third party, which could require us to pay significant royalties, increasing our operating expenses. Even if we do reach a settlement agreement to resolve an intellectual property claim, such settlement agreement could also result in our making a significant monetary payment or paying significant royalties. If a license is not available at all or not available on reasonable terms, we may be required to develop or license a non-infringing alternative, either of which could require significant effort and expense. If we cannot license or develop a non-infringing alternative, we would be forced to limit or stop sales of our offerings and may be unable to effectively compete. Any of these results would adversely affect our business, financial condition and results of operations.

Our products and services use certain software licensed by its authors or other third parties under so-called “open source” licenses. Some of these open source licenses may contain requirements that we make available source code for modifications or derivative works that we create based upon the open source software, and that we license such modifications or derivative works under the terms of a particular open source license or other license granting third parties rights with respect to such software. In certain circumstances, if we combine our proprietary software with certain open source software, we could be required to release the source code for such proprietary software. Additionally, to the extent that we do not comply with the terms of the open source licenses to which we are subject, or such terms are interpreted by a court in a manner different than our own interpretation of such terms, then we may be required to disclose certain of our proprietary software or take other actions that could negatively impact our business. Further, the use of open source software can lead to vulnerabilities that may make our software susceptible to attack, and open source licenses generally do not provide warranties or controls on the origin of the software. While we attempt to utilize open source software in a manner that helps alleviate these risks, our attempts may not be successful.

We do not have internal manufacturing capabilities, and currently rely on contract manufacturers to build all of our products. Our reliance on a limited number of contract manufacturers makes us vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields and costs. We do not currently have long-term supply contracts with our contract manufacturers and they are not obligated to supply products to us for any period, in any specified quantity or at any certain price beyond the single delivery contemplated by the relevant purchase order. While we may enter into long-term master supply agreements with our contract manufacturers in the future as the volume of our business grows in a way that makes these arrangements economically feasible, we may not be successful in negotiating such agreements on favorable terms or at all. If we do enter into such long-term master supply agreements, or enter into such agreements on less favorable terms than we currently have with such manufacturers, we could be subject to binding long-term purchase obligations that may be harmful to our business, including in the event that we do not have the customer demand necessary to utilize the products that we are required to purchase. Any change in our relationships with our contract manufacturers or changes to contractual terms of our agreements with them could adversely affect our financial condition and results of operations.

The revenue that certain of our contract manufacturers generate from our orders represents a relatively small percentage of their overall revenue. As a result, fulfilling our orders may not be considered a priority in the event of constrained ability to fulfill all of their customer obligations in a timely manner. In addition, some of the facilities in which our products are manufactured are located outside of the United States. Our use of international facilities may increase supply risk, including the risk of supply interruptions or reductions in manufacturing quality or controls.

We may be negatively impacted by the deterioration in financial conditions of our limited number of contract manufacturers. If any of our contract manufacturers were unable or unwilling to manufacture the components that we require for our products in sufficient volumes, at high-quality levels, on a timely basis and pursuant to existing supply

agreement terms, due to financial conditions or otherwise, we would have to identify, qualify and select acceptable alternative contract manufacturers. An alternative contract manufacturer may not be available to us when needed or may not be in a position to satisfy our quality or production requirements on commercially reasonable terms, including price and timing. Any significant interruption or delays in manufacturing would require us to reduce or delay our supply of products to our customers or increase our shipping costs to make up for delays in manufacturing, if possible, which in turn could reduce our revenue, cause us to incur delay liquidated damages or other liabilities to our customers, harm our relationships with our customers, damage our reputation or cause us to forego potential revenue opportunities. While we may have contractual remedies against our contract manufacturers for the supply chain malfunctions noted above to support any liabilities to our customers, such remedies may not be sufficient in scope, we may not be able to effectively enforce such remedies and we may incur significant costs in enforcing such remedies.

Our product development, manufacturing and testing processes are complex and require significant technological and production-related expertise. Such processes involve a number of precise steps from design to production. Any change in our processes could cause one or more production errors, requiring a temporary suspension or delay in our production line until the errors can be researched, identified, analyzed and properly addressed and rectified. This may occur particularly as we introduce new products, modify our engineering and production techniques and/or expand our capacity. In addition, delays, disruptions or our failure to maintain appropriate quality assurance processes could result in increased product failures, loss of customers, increased warranty claims, delay liquidated damages claims or other liabilities to our customers, increased production and logistics costs and delays. While we may have contractual remedies against our contract manufacturers for such quality assurance failures to support any liabilities to our customers, such remedies may not be sufficient in scope, we may not be able to effectively enforce such remedies and we may incur significant costs in enforcing such remedies. Any of these developments could have a material adverse effect on our business, financial condition and results of operations.

We depend on a limited number of contract manufacturers for certain key components used to manufacture our products, making us susceptible to quality issues, shortages and price changes. Some of our contract manufacturers have in the past stopped producing or limited their production of our components, faced supply constraints or increased prices on the raw materials for their component, ceased operations or been acquired by, or entered into exclusive arrangements with, one or more of our competitors, and such actions may occur again in the future. Additionally, these manufacturers could stop selling to us at commercially reasonable prices, or at all. Because there are a limited number of contract manufacturers of the key components used to manufacture our products, it may be difficult to quickly identify alternate manufacturers or to qualify alternative components on commercially reasonable terms, and our ability to satisfy customer demand may be adversely affected. Transitioning to or redesigning a product to accommodate a new contract manufacturer would result in additional costs and delays. These outcomes could harm our business or financial performance.

Any interruption in the supply of limited source components for our products would adversely affect our ability to meet scheduled product deliveries to our customers, could result in lost revenue or higher expenses and would harm our business.

We purchase some of our components outside of the United States through arrangements with various international contract manufacturers. Political, social or economic instability in these regions, or in other regions where our products are made, could cause disruptions in trade, including, without limitation, exports to the United States. Actions in various countries, particularly China and the United States, have created uncertainty with respect

to the ability to export certain technologies and tariff impacts on the costs of some of our components. The degree of our exposure is dependent on, among other things, the types of components, including their raw materials and interchangeability, the rates imposed and the timing of the actions or tariffs. Other events that could also cause disruptions to our supply chain include, but are not limited to:

While our contract manufacturers are required to adhere to certain business practices to remain on our approved vendor list, which we monitor on a continuous basis, we do not control our contract manufacturers’ operations or their business practices. The travel restrictions and shelter-in-place orders in response to the COVID-19 pandemic have hindered and may continue to hinder our ability to monitor our contract manufacturers, even with the use of local third party contractors. Additionally, our contract manufacturers may not follow ethical business practices, such as fair wage practices or comply with environmental, safety, labor, sanctions and anti-corruption laws and other local laws or other regulations of which we may not be aware. For example, as we expand our business into foreign jurisdictions, the manufacture of our products may be subject to local content requirements, which require our products to incorporate materials from certain local providers. A lack of demonstrated compliance could damage our reputation and lead us to seek alternative manufacturers, which could increase our costs and result in delayed delivery of our products, product shortages or other disruptions of our operations. Violation of labor or other laws by our contract manufacturers or the divergence of a contract manufacturer’s labor or other practices from those generally accepted as ethical in the United States or other markets in which we do business could also attract negative publicity for us and harm our business.

We rely on a limited number of contract manufacturers and, as a result, a sustained or repeated interruption in the manufacturing of our products by such outsourced manufacturers due to fire, flood, war, pandemic or natural disasters, and/or an interruption in the provision of the required components for our business by these manufacturers may interfere with our ability to sell our products to our customers in a timely manner. The nature of our business and our size makes it difficult to insure some or all of the possible harms that could result if we fail to sell and deliver our products in a timely manner, which may adversely affect our financial results.

Our contract manufacturers rely on commercial ocean transportation for the delivery of a large percentage of our products to customers. The ability of our contract manufacturers to deliver our products via ocean transportation could be adversely impacted by shortages in available cargo capacity, changes by carriers and transportation companies in policies and practices, such as scheduling, pricing, payment terms and frequency of service or increases in the cost of fuel, taxes and labor, and other factors, such as labor strikes and work stoppages, not within their control. For example, the COVID-19 pandemic has resulted in diminished vessel capacity and port detainment of vessels which have caused delays in delivery of our products to project sites. Material interruptions in service or

stoppages in ocean transportation, whether caused by strike, work stoppage, lock-out, slowdown or otherwise, could materially and adversely impact our business, results of operations and financial condition.

Federal, state, local and foreign government bodies provide incentives to owners, end-users, distributors, system integrators and manufacturers of solar energy systems to promote solar electricity in the form of rebates, tax credits and other financial incentives, such as system performance payments, payments of renewable energy credits associated with renewable energy generation and an exclusion of solar energy systems from property tax assessments. For example, the solar ITC provides a U.S. federal income tax credit for developers of commercial solar projects. See “Our Business—Government Incentives” for further information. Under existing tax law, the ITC is 30% for projects that began construction prior to 2020 and are placed in service before 2024, and is reduced to 26% for projects that began construction in 2020, 2021 or 2022 and are placed in service before 2026, to 22% for projects that began construction in 2023 and are placed in service before 2026 and to 10% for projects that began construction after 2023 or placed in service after 2025 regardless of when construction began.

In addition, similar incentives may exist in, or be developed outside, of the United States, which could impact demand for our products and services as we expand our business into foreign jurisdictions. For example, our international customers and end-users may have access to feed-in-tariffs, tax deductions and grants toward equipment purchases. Our ability to successfully penetrate new geographic markets may depend on new countries adopting, to the extent such incentives are not currently in place, and maintaining such incentives to promote solar electricity.

The range and duration of these incentives vary widely by jurisdiction. Our customers typically use our systems for utility scale grid-connected electric power generation projects that sell solar power under a power purchase agreement or into an organized electric market. This segment of the solar industry has historically depended in large part on the availability and size of government incentives and regulations mandating the use of renewable energy. Consequently, the reduction, elimination or expiration of government incentives for grid-connected solar electricity or regulations mandating the use of renewable energy may negatively affect the competitiveness of solar electricity relative to conventional and non-solar renewable sources of electricity, and could harm or halt the growth of the solar electricity industry and our business. These subsidies and incentives may expire on a particular date, end when the allocated funding is exhausted or be reduced or terminated as solar energy adoption rates increase or as a result of legal challenges, the adoption of new statutes or regulations or the passage of time. These reductions or terminations may occur without warning, which would negatively impact our business, financial condition and results of operations.

Corporate social responsibility efforts, such as net zero emission pledges, have fostered private sector investment in solar energy systems in recent years. To the extent that these corporate policies are redirected away from renewable energy in general or solar energy in particular, our business, financial condition and results of operation may be negatively impacted.

In addition, federal, state, local and foreign government bodies have implemented various policies that are intended to promote renewable electricity generally or solar electricity in particular, like RPSs that has been adopted by certain states. RPSs may be reduced or eliminated from time to time, particularly as state-level government administrations change. Additionally, the policies of the Trump administration have created regulatory uncertainty in the renewable energy industry, including the solar energy industry. For example, in June 2017, President Trump announced that the United States would withdraw from participation in the Paris Agreement on climate change mitigation, and in June 2019, the U.S. Environmental Protection Agency issued the final Affordable Clean Energy rule and repealed the Clean Power Plan. While recent elections have resulted in a new presidential administration that may seek to promote renewable energy, its policy initiatives may not be implemented as substantial changes in federal policy depend on legislative and regulatory outcomes that may be difficult to achieve in the current political climate.

In general, the cost of solar power currently exceeds retail electricity rates, and we believe this trend will continue in the near term. Electric utility companies or generators of electricity from other non-solar renewable

sources of electricity may successfully lobby for changes in the relevant legislation in their markets that are harmful to the solar industry. Furthermore, electric utility companies may establish pricing structures or interconnection requirements that could adversely affect our sales and be harmful to the solar generation industry.

Approximately 85.2% and 100% of our 2019 and 2020 revenue, respectively, resulted from sales within the United States and we expect to continue to generate a substantial amount of our revenue from the United States in the future. There are a number of important incentives that are expected to phase down or terminate in the future, which could adversely affect sales of our products in the United States, such as the step-downs of the ITC that resume after 2022 and cease in 2024. Additionally, as we further expand to other countries, changes in incentive programs or electricity policies could negatively affect returns on our investments in those countries as well as our business, financial condition and results of operations.

Federal, state, local and foreign government regulations and policies concerning the broader electric utility industry, as well as internal policies and regulations promulgated by electric utilities and organized electric markets with respect to fees, practices and rate design, heavily influence the market for electricity generation products and services. These regulations and policies often affect electricity pricing and the interconnection of generation facilities, and can be subject to frequent modifications by governments, regulatory bodies, utilities and market operators. For example, changes in fee structures, electricity pricing structures and system permitting, interconnection and operating requirements can deter purchases of renewable energy products, including solar energy systems, by reducing anticipated revenue or increasing costs or regulatory burdens for would-be system purchasers. The resulting reductions in demand for solar energy systems could harm our business, prospects, financial condition and results of operations.

A significant recent development in renewable energy pricing policies in the United States occurred on July 16, 2020, when the Federal Energy Regulatory Commission (“FERC”) issued a final rule amending regulations that implement the Public Utility Regulatory Policies Act (“PURPA”). The net effect of these changes is uncertain, however, in general, FERC’s PURPA reforms have the potential to reduce prices for the output from certain new renewable generation projects while also narrowing the scope of PURPA eligibility for new projects. These effects could reduce demand for PURPA-eligible solar energy systems and could harm our business, prospects, financial condition and results of operations.

In addition, changes in our products or changes in export and import laws and implementing regulations may create delays in the introduction of new products in international markets, prevent our customers from deploying our products internationally or, in some cases, prevent the export or import of our products to certain countries altogether. Any such event could have a material adverse effect on our business, financial condition and results of operations.

Escalating trade tensions, particularly between the United States and China, have led to increased tariffs and trade restrictions, including tariffs applicable to certain raw materials and components for our products or for products used in solar energy projects more broadly. 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 that our contract manufacturers continue to use overseas suppliers of steel and aluminum, these tariffs could result in interruptions in the supply chain and impact costs and our gross margins.

Additionally, in January 2018, the United States decided to impose a tariff on imported solar panels 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. The tariff is currently set at 18%. The United States excluded bifacial panels from the tariff, but later withdrew that exclusion; this is the subject of ongoing litigation, the outcome of which remains uncertain. The tariff may indirectly affect us by impacting the financial viability of solar energy projects, which could in turn reduce demand for our products.

Furthermore, in June 2018, the United States adopted a 25% tariff on a long list of products imported from China under Section 301 of the Trade Act of 1974, including certain power optimizers, which became effective on July 6, 2018. Likewise, in September 2018, the United States adopted a 10% tariff under Section 301 with respect to a list of products imported from China that includes certain inverters, and this tariff became effective on September 24, 2018. Effective on June 1, 2019, the U.S. Trade Representative increased the tariff rate for such products from 10% to 25%. Here, again, the tariff may indirectly affect us by impacting the financial viability of solar energy projects, which could in turn reduce demand for our products.

Tariffs currently in place and the possibility of additional tariffs in the future have created uncertainty in the industry. If the price of solar systems in the United States increases, the use of solar systems could become less economically feasible and could reduce our gross margins or reduce demand for solar systems manufactured and sold, which in turn may decrease demand for our products. Additionally, existing or future tariffs may negatively affect our customers and manufacturing partners. Such outcomes could adversely affect the amount or timing of our revenue, results of operations or cash flows, and continuing uncertainty could cause sales volatility, price fluctuations or supply shortages or cause our customers to advance or delay their purchase of our products. Governments may take further trade-related actions, which may include additional or increased tariffs and trade restrictions, and we may be unable to quickly and effectively react to such actions. While we have taken actions with the intention of mitigating the effect of tariffs on our business by reducing our reliance on China, we may not succeed or be able to continue to do so on attractive terms or at all. For example, in 2019, 90% of our supply chain was sourced from China. However, by the end of 2020, we had qualified suppliers outside of China for all our commodities and reduced the extent to which our supply chain for U.S.-based projects is subject to existing tariffs, as we have entered into partnerships with manufacturers in many other countries worldwide that will be able to independently supply our U.S. customers.

Changes in corporate tax rates, tax incentives for renewable energy projects, the realization of net deferred tax assets relating to our U.S. operations, the taxation of foreign earnings and the deductibility of expenses under future tax reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges in the current or future taxable years, and could increase our future U.S. tax expense, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

The FCPA generally prohibits companies and their intermediaries from making improper payments to foreign government officials for the purpose of obtaining or retaining business. Other countries in which we operate also have anti-bribery laws, some of which prohibit improper payments to government and non-government persons and entities. Prior to the completion of this offering, we will adopt policies that mandate compliance with these anti-bribery laws. However, we currently operate in and intend to further expand into, many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. In addition, due to the level of regulation in our industry, our entry into certain jurisdictions requires substantial government contact where norms can differ from U.S. standards. It is possible that our employees, subcontractors, agents and partners may take actions in violation of our policies and anti-bribery laws. Furthermore, we are subject to rules and regulations of the United States and other countries relating to export controls and economic sanctions, including, but not limited to, trade sanctions administered by the Office of Foreign Assets Control within the U.S. Department of the Treasury, as well as the Export Administration Regulations administered by the Department of Commerce. These regulations may limit our ability to market, sell, distribute or otherwise transfer our products or technology to prohibited countries or persons. Any violation of such laws, even if prohibited by our policies, could subject us to criminal or civil penalties or other sanctions, which could have a material adverse effect on our business, financial condition, cash flows and reputation.

We rely extensively on various information technology systems, including data centers, hardware, software and applications to manage many aspects of our business, including to operate and provide our products and services, to process and record transactions, to enable effective communication systems, to track inventory flow, to manage logistics and to generate performance and financial reports. We are dependent on the integrity, security and consistent operations of these systems and related back-up systems. Our computer and information technology systems and the third party systems upon which we rely are also subject to damage, interruption or shutdown from a number of causes, including computer viruses, malware, phishing or distributed denial-of-service attacks, security breaches or cyber-attacks, which could lead to delays in our business operations or subject us to liability and, if significant or extreme, affect our results of operations. In addition, any interruption in the operation of our website or information technology systems could cause us to suffer reputational harm or to lose sales.

Some aspects of our business involve the collection, receipt, use, storage, processing and transmission of personal information, including that of our customers’ and end-users of our customers’ solar energy systems, website visitors, employees, contract manufacturers and other third parties. We may collect personal information, including names, addresses, e-mail addresses, credit information, and energy production statistics and consumer preferences, some of which is entrusted to third party service providers. We increasingly rely on commercially available systems, software, tools (including encryption technology) and monitoring technologies to provide security and oversight for processing, transmission, storage and protection of confidential information and personal data. Despite the security measures we have in place, our facilities and systems, and those of third parties with which we do business, may be vulnerable to security breaches, acts of vandalism and theft (including misappropriation of our financial resources), computer viruses, misplaced or lost data, programming and/or human errors, or other similar events, and an inadvertent or unauthorized use or disclosure could occur or third parties could gain unauthorized access to this type of confidential information and personal data.

Electronic security attacks designed to gain access to personal, sensitive or confidential data by breaching mission critical systems of large organizations are constantly evolving, and high profile electronic security breaches leading to unauthorized disclosure of confidential information or personal data have occurred recently at a number of major U.S. companies.

Despite our precautions, an electronic security breach in our systems (or in the systems of third parties with which we do business) that results in the unauthorized release of personally identifiable information regarding customers, employees or other individuals or other sensitive data could nonetheless lead to a serious disruption of our operations, financial losses from remedial actions, loss of business or potential liability, including possible punitive damages. As a result of such a breach, we could also be subject to demands, claims and litigation by private parties, and investigations, related actions and penalties by regulatory authorities. Moreover, we could incur significant costs in notifying affected persons and entities and otherwise complying with the multitude of foreign, federal, state and local laws and regulations relating to the unauthorized access to, or use or disclosure of, personal information. In addition, any perceived or actual unauthorized access to, or use or disclosure of, such information could harm our reputation, substantially impair our ability to attract and retain customers and have an adverse impact on our business, financial condition and results of operations.

Finally, as the regulatory environment relating to our obligations to protect such sensitive data becomes increasingly rigorous, with continually developing and growing requirements applicable to our business, compliance with those requirements could result in additional costs. A material failure on our part to comply with such requirements could subject us to regulatory sanctions, including fines and potentially lawsuits. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

There are numerous federal, state, local and foreign laws regarding privacy and the collection, processing, storing, sharing, disclosing, using and protecting of personal information and other data. We are also subject to specific contractual requirements contained in agreements with third parties governing our use and protection of personal information and other data. We generally comply with industry standards and are subject to the terms of our privacy policy and the privacy- and security-related obligations agreed to with third parties. We strive to comply with applicable laws, policies, legal obligations and industry standards relating to privacy and data protection, to the extent possible. However, it is possible that these obligations may be interpreted and applied in new ways or in a manner that is inconsistent from one jurisdiction to another and may conflict with other rules or our practices. Additionally, new laws or regulations could be enacted with which we are not familiar or with which our practices do not comply.

We expect that new industry standards, laws and regulations will continue to be proposed regarding privacy, data protection and information security in many jurisdictions, including the California Consumer Privacy Act (the “CCPA”), which came into effect on January 1, 2020, and the recently passed California Privacy Rights Act (“CPRA”), which amends the CCPA and has many provisions that will go into effect on January 1, 2023. Additionally, the Federal Trade Commission and many state attorneys general are interpreting federal and state consumer protection laws to impose standards for the online collection, use, dissemination and security of data. The impact of the CCPA, CPRA or other future laws, regulations and standards may have on our business is uncertain. Complying with these evolving obligations is costly. For instance, expanding definitions and interpretations of what constitutes “personal data” (or the equivalent) in the United States or other countries may increase our compliance costs and legal liability.

Any failure, or perceived failure, by us to comply with any federal, state, local or foreign privacy or consumer protection-related laws, regulations or other principles or orders to which we may be subject or other legal obligations relating to privacy or consumer protection could adversely affect our reputation, brand and business, and may result in claims, investigations, proceedings or actions against us by governmental entities or others or other penalties or liabilities or require us to change our operations and/or cease using certain data sets.

We currently intend to use the net proceeds to us from this offering for general corporate purposes, including working capital and operating expenses. We may also use a portion of the net proceeds to acquire or invest in businesses, products, services or technologies. However, we do not have binding agreements or commitments for any material acquisitions or investments at this time. See “Use of Proceeds.” Our management will have broad discretion in the allocation of the net proceeds from this offering, and our stockholders may not agree with such allocation. The failure by our management to allocate the net proceeds effectively could have a material adverse effect on our business, financial condition and results of operations. Pending their use, we may invest the net proceeds from this offering in a manner that does not produce income. The decisions made by our management may not result in positive returns on your investment and you will not have an opportunity to evaluate the economic, financial or other information upon which our management bases its decisions.

Prior to this offering, there has been no public market for our common stock. Although we expect to list our common stock on Nasdaq, an active public market for our common stock may not develop or be sustained after this offering. If an active and liquid trading market does not develop, you may have difficulty selling or may not be able to sell any of the shares of our common stock that you purchase.

The market price of our common stock could be subject to significant fluctuations after this offering. The price of our common stock may change in response to fluctuations in our results of operations in future periods and also

may change in response to other factors, including factors specific to companies in our industry. As a result, our share price may experience significant volatility and may not necessarily reflect the value of our expected performance. Among other factors that could affect our stock price are:

Further, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. In addition, the stock prices of many renewable energy companies have experienced wide fluctuations that have often been unrelated to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes or international currency fluctuations, may cause the market price of our common stock to decline.

You may not be able to resell any of your shares of our common stock at or above the initial public offering price. The initial public offering price will be determined by negotiations between us and the representative of the underwriters and may not be indicative of prices that will prevail in the trading market, if a trading market develops, after this offering. If the market price of our common stock after this offering does not exceed the initial public offering price, you may not realize any return on your investment and may lose some or all of your investment.

We have never declared or paid any cash dividends on our common stock. We currently intend to retain any future earnings and do not expect to declare or pay any cash dividends for the foreseeable future. Any future determination to declare cash dividends will be made at the discretion of our board of directors, subject to applicable laws, after taking into account our financial condition, results of operations, capital requirements, general business conditions and other factors that our board of directors may deem relevant. As a result, capital appreciation in the price of our common stock, if any, may be your only source of gain on an investment in our common stock. See “Dividend Policy.”

The trading of our common stock is likely to be influenced by the reports and research that industry or securities analysts publish about us, our business, our market or our competitors. We do not currently have and may never obtain research coverage by securities or industry analysts. If no securities or industry analysts commence coverage of us, the trading price for our common stock would be negatively affected. If we obtain securities or industry analyst coverage but one or more analysts downgrade our common stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more securities or industry analysts ceases to cover us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

In connection with this offering, we intend to file a registration statement with the SEC on Form S-8 providing for the registration of shares of our common stock issued or reserved for issuance under the 2021 Plan. Subject to the satisfaction of vesting conditions and the expiration of lock-up agreements, shares registered under the registration statement on Form S-8 will be available for resale immediately in the public market without restriction. From time to time in the future, we may also issue additional shares of our common stock or securities convertible into common stock to raise additional capital or pursuant to a variety of transactions, including acquisitions. The issuance by us of additional shares of our common stock or securities convertible into our common stock would dilute your ownership of us and the sale of a significant amount of such shares in the public market could adversely affect prevailing market prices of our common stock. We may also seek additional capital through debt financings. The incurrence of indebtedness would result in increased fixed payment obligations and could involve restrictive covenants, such as limitations on our ability to incur additional debt, to make capital expenditures, to create liens, or to redeem stock or declare dividends, that could adversely impact our ability to conduct our business.

The sale of substantial amounts of shares of our common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. Upon completion of this offering, we will have a total of 82,163,552 shares of our common stock outstanding (which shall also be 82,163,552 shares if the underwriters exercise their overallotment option in full, as any new shares issued in connection therewith would equal the number of additional shares that would be subject to the Stock Repurchase in such scenario).

All of the shares of common stock sold in this offering will be freely tradable without restriction or further registration under the Securities Act, except that any shares held by our affiliates, as that term is defined under Rule 144 of the Securities Act (“Rule 144”), may be sold only in compliance with the limitations described in “Shares Eligible for Future Sale.” We, our executive officers, directors and certain holders of our outstanding securities will sign lock-up agreements with the underwriters that will, subject to certain exceptions, restrict the sale of the shares of our common stock and certain other securities held by them for 180 days following the date of this prospectus. Barclays Capital Inc. and BofA Securities, Inc. may, at their discretion and at any time, release all or any portion of the shares or securities subject to any such lock-up agreements. See “Underwriting” for a description of these lock-up agreements.

Based on an assumed initial public offering price of $19.00 per share of common stock (the midpoint of the estimated offering price range set forth on the cover page of this prospectus), purchasers of our common stock in this offering will experience immediate and substantial dilution of $16.67 per share in the pro forma as adjusted net tangible book value per share of common stock from the initial public offering price, and our pro forma as adjusted net tangible book value as of December 31, 2021 after giving effect to this offering would be $2.33 per share. This dilution is due in large part to earlier investors having paid substantially less than the assumed initial public offering price when they purchased their shares. See “Dilution.”

Our directors, executive officers and each of our 5% stockholders and their affiliates, in the aggregate, will beneficially own approximately 70.0% of the outstanding shares of our common stock after this offering, based on the number of shares outstanding as of April 15, 2021 and assuming the underwriters’ over-allotment option is not exercised. As a result, these stockholders, if acting together, will be able to influence or control matters requiring approval by our stockholders, including the election of directors and the approval of mergers, acquisitions or other extraordinary transactions. They may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. This concentration of ownership may have the effect of delaying, preventing or deterring a change of control of our company, could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company and might ultimately affect the market price of our common stock.

Our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law contain or will contain provisions that could have the effect of rendering more difficult, delaying or preventing an acquisition deemed undesirable by our board of directors. Among others, our amended and restated certificate of incorporation and amended and restated bylaws will include the following provisions:

In addition, we are governed by the provisions of Section 203 of the DGCL, which generally prohibits a Delaware corporation from engaging in a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder becomes an “interested” stockholder. For a description of our capital stock, see “Description of Capital Stock.”

Any provision of our amended and restated certificate of incorporation, amended and restated bylaws or Delaware law that has the effect of delaying, preventing or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock and could also affect the price that some investors are willing to pay for our common stock.

Our amended and restated certificate of incorporation will provide that, unless we consent to the selection of an alternative forum, the Delaware Court of Chancery is the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a breach of fiduciary duty owed by any of our directors, officers or other employees to us or to our stockholders, (iii) any action asserting a claim against us arising pursuant to the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws, (iv) any action to interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation or our amended and restated bylaws, (v) any action asserting a claim against us that is governed by the internal affairs doctrine or (vi) any action asserting an “internal corporate claim” as defined in Section 115 of the DGCL; provided, however, that the exclusive forum provisions will not apply to suits brought to enforce any liability or duty created by the Exchange Act or to any claim for which the federal courts have exclusive jurisdiction. Our amended and restated certificate of incorporation will further provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts are the sole and exclusive forum for the resolution of any complaint asserting a right under the Securities Act, subject to a final adjudication in the State of Delaware of the enforceability of such exclusive forum provision. We note that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. The choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provisions contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could materially and adversely affect our business, financial condition and results of operations.

We are an “emerging growth company,” as defined in the JOBS Act. As an emerging growth company, we are not required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, we have reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and we are exempt from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Additionally, as an emerging growth company, we have elected to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. As such, our consolidated financial statements may not be comparable to companies that comply with public company effective dates. Investors may find our shares of common stock less attractive because we may rely on these provisions. If some investors find our shares of common stock less attractive as a result of the foregoing, there may be a less active trading market for our shares and our share price may be more volatile.

As a public company, we will be subject to the reporting requirements of the Exchange Act and the requirements of the Sarbanes-Oxley Act. These requirements may place a strain on our systems and resources. The Exchange Act requires that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal controls over financial reporting. Section 404(a) of the Sarbanes-Oxley Act requires that, beginning with our second annual report following our initial public offering, management assess and report annually on the effectiveness of our internal controls over financial reporting and identify any material weaknesses in our internal controls over financial reporting. If we are unable to comply with the internal controls requirements of the Sarbanes-Oxley Act, then we may not be able to obtain the certifications required by that act, which may preclude us from keeping our filings with the SEC current, and interfere with the ability of investors to trade our securities and our ability to list our shares on any national securities exchange. To maintain and improve the effectiveness of our disclosure controls and procedures, we will need to commit significant resources, hire additional staff and provide additional management oversight. We will be implementing additional procedures and processes for the purpose of addressing the standards and

requirements applicable to public companies. Sustaining our growth also will require us to commit additional management, operational and financial resources to identify new professionals to join our firm and to maintain appropriate operational and financial systems to adequately support expansion. These activities may divert management’s attention from other business concerns and will result in increased costs to us, which could have a material adverse effect on our results of operations, financial condition or business.

As an “emerging growth company” as defined in the JOBS Act, we intend to take advantage of certain temporary exemptions from various reporting requirements including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We have elected to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies, as permitted by the JOBS Act.

As a public company, our management is responsible for establishing and maintaining adequate internal controls over financial reporting. Internal controls over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. generally accepted accounting principles. A material weakness is a deficiency, or a combination of deficiencies, in internal controls over financial reporting such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis.

During the course of preparing for this offering, we determined that we had material weaknesses in our internal controls over financial reporting as of December 31, 2020. Specifically, in connection with the preparation of our consolidated financial statements for the year ended December 31, 2019, we identified certain control deficiencies in the design and operation of our internal controls over financial reporting that constituted the following material weaknesses:

Additionally, the above material weaknesses could result in a misstatement of the aforementioned account balances or disclosures that would result in a material misstatement of the annual or interim financial statements that would not be prevented or detected.

While we have implemented a plan to remediate these weaknesses, which includes hiring additional accounting personnel, drafting and implementing accounting policies and adopting NetSuite as our information technology system, the steps we have taken to date, and that we are continuing to implement, may not be sufficient to remediate these weaknesses or to avoid the identification of material weaknesses in the future, which could impair our ability to accurately and timely report our financial position, results of operations or cash flows, including our filing of quarterly or annual reports with the SEC. Moreover, our failure to remediate the material weaknesses identified above or the identification of additional material weaknesses could prohibit us from producing timely and accurate financial statements, which may adversely affect the market price of our common stock and we could become subject to litigation or investigations by the stock exchange on which our securities are listed, the SEC, or other regulatory authorities, which could require additional financial and management resources.

We estimate that our net proceeds from this offering will be approximately $321.3 million (or approximately $370.3 million if the underwriters exercise their over-allotment option in full) at an assumed initial public offering price of $19.00 per share of common stock, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

Each $1.00 increase (decrease) in the assumed initial public offering price of $19.00 per share of common stock, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would increase (decrease) the net proceeds to us from this offering by approximately $17.2 million, which will be allocated as set forth below, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. Each increase (decrease) of 1,000,000 shares in the number of shares offered by us would increase (decrease) the net proceeds to us from this offering by approximately $17.8 million, which will be allocated as set forth below, assuming the assumed initial public offering price remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. We do not expect that a change in the assumed initial public offering price or the number of shares by these amounts would have a material effect on our use of proceeds from this offering, although it may accelerate the time when we need to seek additional capital.

We intend to use the net proceeds from this offering as follows:

If the net proceeds from this offering are greater than the estimated net proceeds set forth herein, we intend to use the additional proceeds to purchase additional shares of our common stock from the Stock Repurchase Parties at the initial public offering price less the underwriting discounts and commissions. If the net proceeds from this offering are less than the estimated net proceeds set forth herein, we intend to purchase fewer shares of our common stock from the Stock Repurchase Parties and if the net proceeds are less than $181.0 million we will not purchase any shares of our common stock from the Stock Repurchase Parties.

Because we intend to use a portion of the net proceeds from this offering for general corporate purposes, our management will have broad discretion over the use of the net proceeds from this offering. As of the date of this prospectus, we intend to invest the net proceeds that are not used as described above in capital-preservation investments, including short-term interest-bearing investment-grade securities, certificates of deposit or U.S. government backed securities.

We have not declared or paid any cash dividends on our capital stock since our inception. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business, and therefore we do not expect to declare or pay any cash dividends for the foreseeable future. Any future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors, subject to applicable laws, and will depend on a number of factors, including our financial condition, results of operations, prospects, cash requirements and availability, debt repayment obligations, capital expenditure needs, contractual restrictions, covenants in the agreements governing our current and future indebtedness, industry trends, the provisions of Delaware law affecting the payment of dividends and distributions to stockholders and any other factors or considerations our board of directors may regard as relevant.

Our ability to pay dividends may also be restricted by the terms of any credit agreement or any future debt or preferred equity securities of us or our subsidiaries. Accordingly, you may need to sell your shares of our common stock to realize a return on your investment, and you may not be able to sell your shares at or above the price you paid for them. See “Risk Factors—Risks Related to this Offering and Ownership of Our Common Stock—We do not intend to pay dividends on our common stock for the foreseeable future.”

The following table sets forth our cash, restricted cash and capitalization as of December 31, 2020:

Our capitalization following the closing of this offering will be adjusted based on the actual initial public offering price and other terms of this offering determined at pricing. The following table does not give effect to 7,548,253 shares of our common stock that will be issued within twelve months of April 15, 2021 in connection with the settlement of vested RSUs that remain outstanding after the completion of this offering. You should read this table, together with the information contained in this prospectus, including “Use of Proceeds,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes included elsewhere in this prospectus.

Each $1.00 increase (decrease) in the assumed initial public offering price of $19.00 per share of common stock, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would have no impact on each of cash and restricted cash, additional paid-in capital, total stockholders’ equity (deficit) and total capitalization on a pro forma as adjusted basis as a result of the Stock Repurchase, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

Each increase (decrease) of 1,000,000 shares in the number of shares offered by us would have no impact on each of cash and restricted cash, additional paid-in capital, total stockholders’ equity (deficit) and total capitalization on a pro forma as adjusted basis as a result of the Stock Repurchase, assuming the assumed initial public offering price remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

Investors purchasing our common stock in this offering will experience immediate and substantial dilution in the pro forma net tangible book value of their shares of common stock. Dilution in pro forma net tangible book value represents the difference between the initial public offering price per share of our common stock and the pro forma as adjusted net tangible book value per share of our common stock after giving effect to this offering.

Pro forma net tangible book value represents our total tangible assets (total assets less intangible assets) less total liabilities, divided by the pro forma number of outstanding shares of common stock. As of December 31, 2020, our pro forma net tangible book value was $7.5 million, or $0.11 per share of common stock. After giving effect to (i) the filing and effectiveness of our amended and restated certificate of incorporation in Delaware immediately prior to the closing of this offering, (ii) the issuance and sale of 18,421,053 shares of our common stock in this offering at an assumed initial public offering price of $19.00 per share of common stock, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us and (iii) the Stock Repurchase, our pro forma as adjusted net tangible book value as of December 31, 2020 would have been approximately $188.5 million, or $2.33 per share of common stock. This represents an immediate increase in pro forma as adjusted net tangible book value of $2.22 per share of common stock to our existing stockholders and an immediate dilution of $16.67 per share of common stock to new investors participating in this offering. The following table does not give effect to 7,548,253 shares of our common stock that will be issued within twelve months of April 15, 2021 in connection with the settlement of vested RSUs that remain outstanding after the completion of this offering.

The following table illustrates this dilution on a per share basis to new investors:

Each $1.00 increase (decrease) in the assumed initial public offering price of $19.00 per share of common stock, the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would have no impact on our pro forma as adjusted net tangible book value and the dilution per share to new investors participating in this offering as a result of the Stock Repurchase assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

Each increase (decrease) of 1,000,000 in the number of shares of common stock offered by us would have no impact on our pro forma as adjusted net tangible book value and the dilution per share to new investors participating in this offering as a result of the Stock Repurchase, assuming that the assumed initial public offering price remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

If the underwriters exercise their over-allotment option in full, the pro forma as adjusted net tangible book value per share after the offering would be $2.84 per share of common stock, the increase in the pro forma net tangible book value per share to existing stockholders would be $2.73 per share of common stock, and the pro forma as adjusted dilution to new investors participating in this offering would be $16.16 per share of common stock, in each case assuming an initial public offering price of $19.00 per share of common stock, the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

The following table summarizes, on the pro forma as adjusted basis described above as of December 31, 2020, the difference between existing stockholders and new investors participating in this offering with respect to the number of shares purchased from us, the total consideration paid to us and the average price per share paid by our

existing stockholders or to be paid by new investors participating in this offering at an assumed initial public offering price of $19.00 per share of common stock, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

Each $1.00 increase (decrease) in the assumed initial public offering price of $19.00 per share of common stock, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would increase (decrease) total consideration paid by new investors by approximately $17.2 million and total consideration paid by all stockholders by approximately $17.2 million, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

We may also increase (decrease) the number of shares of common stock we are offering. An increase (decrease) of 1,000,000 in the number of shares of common stock offered by us would increase (decrease) total consideration paid by new investors by approximately $17.8 million and total consideration paid by all stockholders by approximately $17.8 million, assuming that the assumed initial public offering price remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

If the underwriters exercise their over-allotment option in full, the number of shares of common stock held by our existing stockholders will be further reduced to 62,485,954, or 75% of the total shares of common stock outstanding after this offering and the number of shares of common stock held by our new investors will be further increased to 21,184,210, or 25% of the total shares of common stock outstanding after this offering.

In addition, to the extent we issue any additional securities under our equity incentive plans or any outstanding stock options are exercised, or we issue any other securities or convertible debt in the future, investors participating in this offering will experience further dilution.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes and other information included elsewhere in this prospectus. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from such forward-looking statements. Factors that could cause or contribute to those differences include, but are not limited to, those identified below and those discussed in the sections titled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” included elsewhere in this prospectus. Additionally, our historical results are not necessarily indicative of the results that may be expected in any future period.

We are a global provider of advanced solar tracker systems, supported by proprietary software designed to increase energy production from our tracker systems and support our customers in project design and development, and value-added engineering services that assist customers in optimizing our products and reducing total project costs. Our mission is to provide differentiated products, software and services that maximize energy generation and cost savings for our customers, and to help facilitate the continued growth and adoption of solar power globally. Trackers significantly increase the amount of solar energy produced at a solar installation by moving solar panels throughout the day to maintain an optimal orientation relative to the sun. Our systems offer efficiency gains relative to other tracker systems due to our tracker’s enhanced design, which includes a two-panel in-portrait format and independent rows, and its optimization for use with bifacial panels. Additionally, these efficiency gains can be enhanced by our proprietary software solutions. Our customers include leading project developers, solar asset owners and EPC contractors that design and build solar energy projects. Our team of experienced renewable energy professionals is focused on delivering compelling value to customers across the full solar energy project lifecycle, including at the development, construction and operations phases.

We currently offer tracking and software solutions targeting the utility-scale solar energy markets to current and potential customers in the United States, Asia, the Middle East, North Africa and Australia. In both 2019 and 2020, we derived the majority of our revenue from EPC contractors in the United States. We expect this revenue profile to shift over time as project developers and solar asset owners make more direct purchases of solar installations and as we continue to expand our global footprint in Latin America, Europe and certain other markets.

Our corporate headquarters is located in Austin, Texas, and we have a training and technology development site in Aurora, Colorado. To assist with our global expansion effort, we have grown our sales and support network abroad, with employees located in Australia, India, the Middle East, China and South-East Asia as of December 31, 2020. As of December 31, 2019, we had 64 full-time employees. As of December 31, 2020, we had 178 full-time employees.

Investment in Technology and Personnel. We invest in both the people and technology behind our products. We intend to continue making significant investments in the technology for our products and expansion of our patent portfolio to attract and retain customers, expand the capabilities and scope of our products, and enhance user experience. We also intend to make significant investments to attract and retain employees in key positions, including sales leads, engineers, software developers, quality assurance personnel, supply chain personnel, product management, and operations personnel, to help us drive additional efficiencies across our marketplace and, in the case of sales leads, to continue to enhance and diversify our sales capabilities, including international expansion.

Megawatts Shipped and Average Selling Price. The primary operating metric we use to evaluate our sales performance and to track market acceptance of our products from year-to-year is the change in MW shipped from period to period. MW are measured for each individual project and are calculated based on the expected output of that project once installed and fully operational. We also utilize metrics related to price and cost of goods sold per MW, including the change in average selling price (“ASP”) from period to period and cost per watt. ASP is calculated by dividing total revenue by total MW and cost per watt is calculated by dividing total costs of goods sold by total MW. These metrics enable us to evaluate trends in pricing, manufacturing cost and customer profitability.

Government Regulations. Changes in the U.S. trade environment, including the imposition of import tariffs, continue to affect the amount and timing of our revenue, results of operations and 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 raw materials and components for our products. We have taken measures with the intention of mitigating the effect of tariffs on our business by reducing our reliance on China. In 2019, 90% of our supply chain was sourced from China. However, by the end of 2020 we had qualified suppliers outside of China for all our commodities and reduced the extent to which our supply chain for U.S.-based projects is subject to existing tariffs, as we have entered into partnerships with manufacturers in the United States, Mexico, Canada, Spain, Brazil, Turkey, Saudi Arabia, India, China, Vietnam and Korea to diversify our supply chain and optimize costs.

On March 11, 2020, the World Health Organization declared that the worldwide spread and severity of a new coronavirus, referred to as COVID-19, was severe enough to be characterized as a pandemic. In response to the continued spread of COVID-19, governmental authorities in the United States and around the world have imposed various restrictions designed to slow the pace of the pandemic, including restrictions on travel and other restrictions that prohibit employees from going to work, including in cities where we have offices, employees and customers, causing severe disruptions in the worldwide economy. While our day-to-day operations have been impacted, we have suffered less immediate impact as most of our staff can work remotely and can continue to develop our product offerings and we have been able to continue to source materials and install our products. As a result, we have not seen a significant impact on our operations, management will continue to monitor the impact of the global situation on our financial condition, cash flows, operations, contract manufacturers, industry, workforce and customer relationships. However, we have experienced significant supply chain disruptions that have caused delays in product deliveries due to diminished vessel capacity and port detainment of vessels as a consequence of the COVID-19 pandemic, which have contributed to an increase in lead times for delivery of our tracker systems. Additionally, ground operations at project sites have been impacted by health-related restrictions, shelter-in-place orders and worker absenteeism, which resulted in delays in project completion in 2020, and these restrictions have also hindered our ability to provide on-site support to our customers and conduct inspections of our contract manufacturers.

We present Adjusted EBITDA, Adjusted Net Loss and Adjusted EPS as supplemental measures of our performance. We define Adjusted EBITDA as net loss plus (i) income tax benefit, (ii) interest expense, (iii) depreciation expense, (iv) amortization of intangibles, (v) stock-based compensation and (vi) loss (income) from unconsolidated subsidiary. We define Adjusted Net Loss as net loss plus (i) amortization of intangibles, (ii) stock-based compensation, (iii) loss (income) from unconsolidated subsidiary and (iv) income tax benefit of adjustments. Adjusted EPS is defined as Adjusted Net Loss on a per share basis using the weighted average diluted shares outstanding and excluding the effect of the Forward Stock Split.

Adjusted EBITDA, Adjusted Net Loss and Adjusted EPS are intended as supplemental measures of performance that are neither required by, nor presented in accordance with, U.S. generally accepted accounting principles (“GAAP”). We present Adjusted EBITDA, Adjusted Net Loss and Adjusted EPS because we believe they assist investors and analysts in comparing our performance across reporting periods on an ongoing basis by excluding items that we do not believe are indicative of our core operating performance. In addition, we use Adjusted EBITDA, Adjusted Net Loss and Adjusted EPS to evaluate the effectiveness of our business strategies.

Among other limitations, Adjusted EBITDA, Adjusted Net Loss, and Adjusted EPS do not reflect (i) our cash expenditures, or future requirements, for capital expenditures or contractual commitments, and (ii) the impact of certain cash charges resulting from matters we consider not to be indicative of our ongoing operations. Further, the adjustments noted in Adjusted EBITDA do not reflect the impact of any income tax expense or benefit. Additionally, other companies in our industry may calculate Adjusted EBITDA, Adjusted Net Loss, and Adjusted EPS differently than we do, which limits its usefulness as a comparative measure.

Because of these limitations, Adjusted EBITDA, Adjusted Net Loss and Adjusted EPS should not be considered in isolation or as substitutes for performance measures calculated in accordance with GAAP and you should not rely on any single financial measure to evaluate our business. These non-GAAP financial measures, when presented, are reconciled to the most closely applicable GAAP measure as disclosed below.

The following table reconciles net loss to Adjusted EBITDA for the years ended December 31, 2019 and 2020, respectively:

The following table reconciles net loss to Adjusted Net Loss and Adjusted EPS for the years ended December 31, 2019 and 2020, respectively:

The following discussion describes certain line items in our consolidated statements of operations.

We generate our revenue in two streams – Product revenue and Service revenue. Product revenue is derived from the sale of Voyager Trackers, customized components of Voyager Trackers, individual part sales for certain specific transactions and sale of term-based software licenses. Revenue from the sale of Voyager Trackers and customized components of Voyager Trackers is recognized over time, as work progresses, utilizing an input measure of progress determined by cost incurred to date relative to total expected cost on these projects to correlate with our performance in transferring control over Voyager Trackers and its components. Revenue from the sale of a Voyager Tracker’s individual parts is recognized point-in-time as and when control transfers based on the terms of the contract. Revenue from sale of term-based software licenses is recognized upon transfer of control to the customer. Service revenue includes revenue from shipping and handling services, subscription-based enterprise licensing model and maintenance and support services in connection with the term-based software licenses. Revenue for shipping and handling services is recognized over time based on shipping terms of the arrangements. Subscription revenue, which is derived from a subscription-based enterprise licensing model, and support revenue, which is derived from ongoing security updates and maintenance, are generally recognized on a straight-line basis over the term of the contract.

Our customers include project developers, solar asset owners and EPC contractors that design and build solar energy projects. For each individual solar project, we enter into a contract with our customers covering the price, specifications, delivery dates and warranty for the products being purchased, among other things. Our contractual delivery period for Voyager Trackers and related parts can vary between eight weeks and 16 weeks. Contracts can range in value from tens of thousands to tens of millions of dollars. Our revenue from software products and engineering services was immaterial for the years ended December 31, 2019 and 2020.

Our revenue is affected by changes in the volume and ASP of our solar tracking systems purchased by our customers and volume of sales of software products and engineering services, among other things. The ASP of our solar tracker systems and quarterly volume of sales is driven by the supply of, and demand for, our products, changes in product mix, geographic mix of our customers, strength of competitors’ product offerings and availability of government incentives to the end-users of our products. Additionally, our revenue may be impacted by seasonality and variability related to ITC step-downs and construction activity as well as the cold weather. See “Our Business—Seasonality.”

In 2019, approximately 85.2% of our revenue was attributable to sales within the United States, with the remainder attributable to sales in South-East Asia and Europe. In 2020, approximately 100% of our revenue was attributable to sales within the United States. Our revenue growth is dependent on continued growth in the number of solar tracker projects and engineering services we win in competitive bidding processes and growth in our software sales each year, as well as our ability to increase our market share in each of the geographies in which we currently compete, expand our global footprint to new emerging markets, grow our production capabilities to meet demand and continue to develop and introduce new and innovative products that address the changing technology and performance requirements of our customers, among other things.

Cost of revenue consists primarily of Voyager Trackers’ raw material costs, including purchased components, as well as costs related to freight and delivery, product warranty, supply chain personnel and consultants, insurance and customer support. Personnel costs include both direct labor costs as well as costs attributable to any individuals whose activities relate to the procurement, installation and delivery of the finished product and provision of services. Cost of revenue for our software products was immaterial for the years ended December 31, 2019 and 2020.

We subcontract to third party contract manufacturers to manufacture and deliver our products directly to our customers. Our product costs are affected by the underlying cost of raw materials procured by these contract manufacturers, including steel and aluminum; component costs, including electric motors and gearboxes; technological innovation in manufacturing processes; and our ability to achieve economies of scale resulting in lower component costs. We do not currently hedge against changes in the price of raw materials, but we continue to explore opportunities to mitigate the risks of foreign currency and commodity fluctuations through the use of hedges and foreign exchange lines of credit. Some of these costs, primarily personnel, are not directly affected by sales volume.

Our full-time employee headcount in operations and support capacities has grown from 28 as of December 31, 2019 to 90 as of December 31, 2020. We expect to continue to increase our headcount as we scale our business.

Gross profit may vary from quarter-to-quarter and is primarily affected by our ASP, product costs, product mix, customer mix, geographical mix, shipping method, warranty costs and seasonality.

Operating expenses consist of research and development expenses, selling and marketing expenses and general and administrative expenses. Personnel-related costs are the most significant component of our operating expenses and include salaries, benefits, bonuses, commissions and stock-based compensation expenses.

Our full-time employee headcount in research and development, sales and marketing and general and administrative capacities has grown from 25, three and eight as of December 31, 2019 to 43, 13 and 32 as of December 31, 2020, respectively, and we expect to continue to hire new employees to support our growth.

The timing of these additional hires could materially affect our operating expenses in any particular period, both in absolute dollars and as a percentage of revenue. We expect to continue to invest substantial resources to support our growth and anticipate that each of the following categories of operating expenses will increase in absolute dollar amounts for the foreseeable future.

Research and development expenses consist primarily of salaries, employee benefits, stock-based compensation expenses and travel expenses related to our engineers performing research and development activities to originate, develop and enhance our products. Additional expenses include consulting charges, component purchases, legal fees for registering patents and other costs for performing research and development on our software products.

Selling and marketing expenses consist primarily of salaries, employee benefits, stock-based compensation expenses and travel expenses related to our sales and marketing and business development personnel. Additionally, selling and marketing expenses include costs associated with professional fees and support charges for software subscriptions and licenses, trade shows and conventions.

We expect an increase in the number of sales and marketing personnel in connection with the expansion of our global sales and marketing footprint as we enter new markets. The majority of our sales and marketing expenses in 2019 and 2020 were related to customers in the United States and business development in other parts of the world. As of December 31, 2020, we have a sales presence in the United States, Asia , the Middle East, North Africa and Australia. We intend to continue to expand our sales presence and marketing efforts to additional countries.

General and administrative expenses consist primarily of salaries, employee benefits, stock-based compensation expenses, and travel expenses related to our executives, finance team, and the administrative employees. It also consists of legal, consulting, and professional fees, rent and lease expenses pertaining to our international offices, business insurance costs and other costs. We also expect that after completion of this offering, we will incur additional audit, tax, accounting, legal and other costs related to compliance with applicable securities and other regulations, as well as additional insurance, investor relations and other costs associated with being a public company.

Interest expense consists of interest payments, annual amortization of debt issuance costs and loss on debt extinguishment in connection with our Secured Promissory Notes which we sold through a private placement and which we had repaid the principal in full as of December 31, 2020, and a revolving line of credit with Western Alliance Bank, which matures on June 10, 2021 (See “Debt Obligations” below).

Benefit from income taxes consists primarily of income taxes related to foreign and state jurisdictions in which we conduct business.

Loss (Income) from unconsolidated subsidiary is comprised of income/expense allocation from our equity method investment.

The following tables set forth our consolidated statement of operations as well as other financial data management considers meaningful for 2019 and 2020. We have derived this data from our consolidated financial statements included elsewhere in this prospectus. This information should be read in conjunction with our consolidated financial statements and related notes included elsewhere in this prospectus. The results of historical periods are not necessarily indicative of the results of operations for any future period.

Product revenue for the year ended December 31 ,2020 was $158.9 million, an increase of $115.8 million, or 269%, as compared to $43.1 million for the year ended December 31, 2019, primarily driven by a 250% increase in MW shipped due to new projects with existing customers, as well as projects for new customers in the year ended December 31, 2020. New customers represented 89% of the additional MW shipped in 2020. We increased our ASP by 2.8% from the year ended December 31, 2019 to the year ended December 31, 2020, primarily as a result of a shift in the geographic mix of our projects toward projects in the United States.

Service revenue for the year ended December 31, 2020 was $28.4 million, and increase of $18.4 million, or 183%, as compared to $10.0 million for the year ended December 31, 2019, primarily driven by an increase in shipping and logistics revenue on Voyager Tracker sales due to a 250% increase in MW shipped to our U.S. customers.

Cost of revenue for the year ended December 31, 2020 was $183.7 million, an increase of $128.6 million, or 234%, as compared to $55.1 million for the year ended December 31, 2019, primarily driven by the aforementioned increase in MW shipped. Cost of revenue for the year ended December 31, 2020 was also impacted by approximately $14.0 million in expenditures related to certain retrofits, remediations and product reconfigurations for certain of our solar tracker systems that had been previously installed, or were in the process of being installed, at customer sites. We undertook these activities after identifying these opportunities for such systems for our customers. In addition, we had a slight reduction in our cost per MW due to improvements in scale and diversification of our supply chain which reduced tariff costs.

Our gross profit for the year ended December 31, 2020 increased by $5.6 million, or 287%, as compared to the year ended December 31, 2019 due to the above stated reasons.

Research and development expenses for the year ended December 31, 2020 were $5.2 million, an increase of $1.3 million, or 32%, as compared to $4.0 million for the year ended December 31, 2019. The increase in expenses was primarily attributable to an increase of $1.5 million in personnel-related expenses, including stock-based compensation expense, due to a net increase in headcount by 18 for the research and development of our products, an increase of $0.5 million in legal fees for registering patents and other related consulting and recruiting fees, an increase of $0.4 million in facilities and equipment related expenses, partially offset by a $1.1 million decrease in research and development expenses related to Voyager Tracker technology as its development cycle ended in the year ended December 31, 2019. Research and development expenses as a percentage of revenue decreased from 7% for the year ended December 31, 2019 to 3% for the year ended December 31, 2020.

Selling and marketing expenses for the year ended December 31, 2020 were $3.5 million, an increase of $1.6 million, or 87%, as compared to $1.9 million for the year ended December 31, 2019. The increase in sales and marketing expenses was primarily attributable to an increase in personnel-related expenses, including stock-based compensation expense, of $2.5 million due to a net increase in headcount by 10, a $0.1 million increase in various consulting and recruiting fees, a decrease in bad debt expense of $0.5 million and an increase of $0.1 million in expenses pertaining to IT software. The increase was partially offset by a $0.3 million reduction in advertising

expenses associated with trade shows and conventions and other business development expenses, and a decrease of $0.3 million related to travel expenses of sales personnel. Sales and marketing expenses as a percentage of revenue decreased from 4% for the year ended December 31, 2019 to 2% for the year ended December 31, 2020.

General and administrative expenses for the year ended December 31, 2020 were $11.8 million, an increase of $7.2 million, or 159%, as compared to $4.6 million for the year ended December 31, 2019. The increase in general and administrative expenses was primarily attributable to an increase of $4.0 million in personnel-related expenses, including stock-based compensation expense, due to a net increase in headcount by 24, an increase of $1.9 million in professional fees for consulting, legal and accounting services, an increase of $0.2 million related to overall travel expenses, an increase of $0.3 million related to office equipment, an increase of $0.6 million in business insurance costs and an increase of $0.2 million pertaining to rent, lease and other office expenses in line with an increase in headcount. General and administrative expenses as a percentage of revenue decreased from 9% for the year ended December 31, 2019 to 6% for the year ended December 31, 2020.

Interest expense consists of interest expense, annual amortization of debt issuance costs and loss on debt extinguishment in connection with our Secured Promissory Notes which we had repaid the principal in full as of December 31, 2020 and a revolving line of credit with Western Alliance Bank, which matures on June 10, 2021. Interest expense, net for the year ended December 31, 2020 remained largely flat compared to the year ended December 31, 2019.

Income from unconsolidated subsidiary for the year ended December 31, 2020 was $1.4 million, an increase of $2.1 million, or 297%, as compared to a $0.7 million loss for the year ended December 31, 2019. This increase resulted from recording $1.4 million of income from our investment in Dimension Energy LLC (“Dimension”) for the year ended December 31, 2020, as compared to a loss from such investment for the year ended December 31, 2019. Dimension is a community solar developer based in Atlanta, Georgia that provides renewable energy solutions for local communities in the United States. This increase was primarily due to the fact that Dimension generated $22.6 million of revenue for the year ended December 31, 2020, as compared to no revenue for the year ended December 31, 2019. The community solar development cycle is approximately 18 to 24 months and Dimension began development activity in 2018, therefore the initial revenue was recognized in fiscal year 2020. For further information, see Note 6 to our consolidated financial statements included elsewhere in this prospectus.

As a result of the factors discussed above, our net loss for the year ended December 31, 2020 was $15.9 million, an increase of $2.4 million, or 18%, as compared to $13.5 million for the year ended December 31, 2019.

Since our inception, we have financed our operations primarily through sales of shares of common stock, issuance of debt and payments from our customers. During the year ended December 31, 2019, we issued 444,489 shares of common stock for an aggregate amount of $6.0 million. In March 2020, we sold 1,111,112 shares of common stock at $27.00 per share for an aggregate purchase price of $30.0 million. The proceeds are available for working capital and other corporate purposes. As of December 31, 2020, we had outstanding borrowings of $1.0 million from a revolving line of credit, payable on June 10, 2021, and an outstanding balance for the Paycheck Protection Program (“PPP”) loan of $0.8 million, which matures on April 30, 2022. The PPP loan and the related accrued interest were fully forgiven on January 20, 2021. Our principal uses of cash in recent periods have been to fund our operations, invest in research and development, repay our borrowings and make equity investments.

We believe our existing cash and other components of working capital will be sufficient to meet our needs for at least the next 12 months. Our future capital requirements will depend on many factors including our revenue growth rate, billing frequency, the timing and extent of spending to support further sales and marketing and research and development efforts, as well as expenses associated with our timing and extent of additional capital expenditures to invest in existing and new office spaces. We may in the future enter into arrangements to acquire or invest in related products, technologies, software and services, and we may need to seek additional equity or debt financing, which may not be available on terms acceptable to us or at all.

We intend to maintain appropriate debt levels based upon cash flow expectations, our overall cost of capital and expected cash requirements for our operations, such as systems and project development activities in certain international regions. Any incremental debt financings could result in increased debt service expenses and/or restrictive covenants, which could limit our ability to pursue our strategic plans.

The following table shows our cash flows from operating activities, investing activities and financing activities for the stated periods:

During 2019, net cash used in operating activities was $0.3 million, primarily due to a net loss of $13.5 million which is reflective of our current investment in growing our operations. We intend to continue investing in our operations in coming years. This was offset by $4.3 million in non-cash charges and a net change of $8.9 million in our net operating assets and liabilities. Non-cash adjustments primarily related to (i) warranty provision of $2.1 million attributable to warranties issued with increased sales of Voyager Trackers, (ii) stock-based compensation expense of $0.9 million, (iii) loss from unconsolidated subsidiary of $0.7 million, which represented our share of loss from our equity method investment, (iv) depreciation and amortization expense of $0.4 million, (v) bad debt expense of $0.4 million and (vi) recognition of a warranty asset of $0.3 million for amounts expected to be recoverable from

our contract manufacturers. The net change in our operating assets and liabilities was primarily attributable to a net increase in deferred revenue of $19.7 million, partially offset by a $13.8 million increase in accounts receivable, both of which were due to the increase in revenue from sales of Voyager Trackers in 2019. Additionally, accounts payable increased by $7.8 million due to increases in procurement and supply chain activity to support our revenue growth and accrued expenses and other liabilities increased by $3.4 million. These increases were partially offset by (i) a decrease of $0.3 million in accrued interest on related party debt, (ii) an increase in prepaid and other current assets of $3.2 million and (iii) an increase in other non-current assets of $0.2 million in line with our increased operating activities, and inventories of $4.5 million to support expected increases in sales in subsequent years.

During 2020, net cash used in operating activities was $0.5 million primarily due to a net loss of $15.9 million which is reflective of our current investment in growing our operations and expanding our presence to additional countries. This was offset by $7.5 million in non-cash charges and a net change of $7.9 million in our net operating assets and liabilities. Non-cash adjustments primarily related to (i) a warranty provision of $7.9 million attributable to warranties issued with increased sales of Voyager Trackers, (ii) a stock-based compensation expense of $1.8 million in line with overall increase in headcount, (iii) income from unconsolidated subsidiary of $1.4 million, which represented our share of profit from our equity method investment, (iv) recognition of $1.0 million for warranty amounts expected to be recoverable from our contract manufacturers, (v) loss on debt extinguishment of $0.1 million and (vi) other non-cash items of $0.1 million. The net change in our operating assets and liabilities was primarily attributable to a net increase in deferred revenue of $3.1 million, partially offset by a $9.7 million increase in accounts receivable, both of which were due to the increase in sales of Voyager Trackers in 2020. Additionally, accounts payable increased by $8.9 million due to increases in procurement and supply chain activity to support our revenue growth, accrued expenses and other liabilities increased by $7.2 million. These increases were partially offset by (i) a decrease in inventories of $2.8 million in line with increased sales, (ii) an increase in prepaid and other current assets of $2.8 million due to increases in advances to suppliers, (iii) a decrease of $0.5 million for operating lease assets, (iv) an increase of $0.7 million in current and non-current liabilities, (v) a decrease of $0.1 million in accrued interest on related party debt and (vi) an increase of $1.7 million in other non-current assets.

During 2019, net cash used in investing activities was $0.02 million, respectively, which was attributable to the purchase of property and equipment.

During 2020, net cash provided by investing activities was $1.9 million, of which $2.1 million was attributable to distributions received from unconsolidated subsidiary as return of investment, offset by $0.2 million used to purchase property and equipment.

During 2019, net cash provided by financing activities was $7.0 million, consisting of proceeds from stock issuances of $6.0 million and proceeds from borrowings of $1.0 million.

During 2020, net cash provided by financing activities was $23.8 million, consisting of proceeds from stock issuances of $30.0 million and proceeds from borrowings of $0.8 million, offset by $7.0 million repayment in full of the Secured Promissory Notes.

On January 30, 2017, we sold $7.0 million in aggregate principal amount of secured promissory notes (the “Secured Promissory Notes”) through a private placement. Those notes bore interest at a fixed rate of 5% per annum, payable at maturity. In connection with the issuance of the Secured Promissory Notes, we issued 25,000 shares of common stock for every $250,000 of notes purchased. As of December 31, 2019, the full $7.0 million of aggregate principal amount of Secured Promissory Notes remained outstanding. We repaid the principal in full during the year ended December 31, 2020 and recorded a loss on debt extinguishment of $0.1 million in interest expense, net in the Consolidated Statement of Operations. Interest expense on the Secured Promissory Notes was $0.4 million and $0.4 million for the years ended December 31, 2019 and 2020, respectively.

On June 17, 2019, we entered into a revolving line of credit agreement with the Western Alliance Bank for a total aggregate principal amount of $1.0 million, which matures on June 10, 2021. The revolving line of credit is part of our relationship with the lender and the lender also provides additional credit support in the form of surety bonds to secure our performance obligations for specific projects and customers. The revolving line of credit is secured by cash held in an account with the lender and bears a variable rate of interest, based on movement of an independent index which was at 5.5% per annum when we entered into the agreement. We make regular monthly payments of all interest accrued as of each payment date. As of December 31, 2019, and 2020, the outstanding balance for the revolving line of credit was $1.0 million, payable on June 10, 2021. Interest expense on the revolving line of credit was $0.1 million and $0.1 million for the years ended December 31, 2019 and 2020, respectively.

On April 30, 2020, we received a PPP loan pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) in the amount of $0.8 million. The PPP loan has a two-year term maturing on April 30, 2022 and bears a fixed interest rate of 1%. Under the terms of the CARES Act the loan is eligible for forgiveness, in part or whole, if the proceeds are used to retain and pay employees and for other qualifying expenditures. The PPP loan and the related accrued interest were fully forgiven on January 20, 2021. Interest expense on the PPP loan was not material for the year ended December 31, 2020.

We prepare our consolidated financial statements in accordance with GAAP. The preparation of consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by our management. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates. Critical accounting policies and estimates are those that we consider the most important to the portrayal of our financial condition and results of operations because they require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain.

We believe that the accounting policies described below involve a significant degree of judgment and complexity. Accordingly, we believe these are the most critical to aid in fully understanding and evaluating our consolidated financial condition and results of operations. For further information, see Note 2 to our consolidated financial statements included elsewhere in this prospectus.

We derive revenue primarily from the sale of: (1) Voyager Trackers and customized components of Voyager Tracker, (2) individual parts of a Voyager Tracker for certain specific transactions, (3) shipping and handling services, (4) term-based software licenses, (5) maintenance and support services for the term-based software licenses and (6) subscription services. Product revenue includes revenue from Voyager Trackers, individual part sales for certain specific transactions and sale of term-based software licenses. Service revenue includes revenue from shipping and handling services, subscription-based enterprise licensing model, and maintenance and support services in connection with the term-based software licenses.

We recognize revenue from the sale of Voyager Trackers, software and engineering services. We contract with customers for the sale of Voyager Trackers under two different types of arrangements: (i) Purchase Agreements and Equipment Supply Contracts and (ii) sale of individual parts of a Voyager Tracker. We recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services by following a five-step process: (i) identify the contract

with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when or as we satisfy a performance obligation. Once the contract is identified, we progress in this process as further described below.

Identify the performance obligations in the contract: We enter into contracts that can include various combinations of products and services, which are either capable of being distinct and accounted for as separate performance obligations or as one performance obligation, as the majority of tasks and services is part of a single project or capability. However, determining whether products or services are considered distinct performance obligations that should be accounted for separately versus together may sometimes require significant judgment. Performance obligations include the sale of Voyager Trackers, customized components of Voyager Tracker, sale of individual parts of a Voyager Tracker for certain specific transactions, shipping and handling services, sale of term-based software licenses, maintenance and support services for the term-based software licenses and sale of software as a service subscription.

Allocate the transaction price to performance obligations in the contract: We use the expected cost-plus margin approach based on hardware, labor and related overhead cost to estimate the standalone selling price of a Voyager Tracker, customized components of Voyager Tracker, and individual parts of a Voyager Tracker for certain specific transactions, with the estimate of the margin being based on our expectations, competition, industry metrics and customer-specific requirements. We use the adjusted market assessment approach for all other performance obligations except shipping, handling and logistics. For shipping, handling and logistics performance obligations, we use a residual approach to calculate the standalone selling price because of the highly variable and broad range of prices charged to various customers for these performance obligations in the contracts.

Recognize revenue when or as we satisfy a performance obligation: Our performance obligations for a specific customer’s Voyager Tracker or customized components of Voyager Tracker are satisfied over time utilizing an input measure of progress determined by cost-to-cost measures on these projects because we do not create an asset with an alternative use to us, due to the highly customized nature of our product, and we have an enforceable right to payment for performance completed to date. We measure the costs incurred on these projects based on costs incurred by our contract manufacturers as Voyager Trackers are produced, and compare that to total budgeted costs for the project to determine progress, adjusted for any project specific facts and circumstances that could impact the measurement of the extent of progress. Our performance obligation for shipping and handling services is satisfied over time as the services are delivered over the term of the contract. Sales of our subscription services and other services are recognized on a straight-line basis over the contract period. Our performance obligations for individual part sales for certain specific transactions are recognized point-in-time as and when control transfers based on the terms of the contract. Our performance obligations for term-based software licenses are recognized point-in-time as and when control transfers based on delivery of license.

The timing of revenue recognition, billing and cash collection results in the recognition of accounts receivable, unbilled receivables and deferred revenue in our consolidated balance sheet. We did not have substantial contract assets as of December 31, 2019 or 2020. We may receive advances or deposits from our customers, before revenue is recognized, resulting in contract liabilities. We refer to contract liabilities as “deferred revenue” in our consolidated financial statements and related disclosures.

We estimate the fair value of stock options granted to employees and directors using the Black-Scholes option-pricing model. The grant date fair value of stock options is recognized as compensation expense on a straight-line basis over the requisite service period. Forfeitures are accounted for when they occur.

The Black-Scholes model considers several variables and assumptions in estimating the fair value of stock-based awards. These variables include:

Fair value of common stock: Because our common stock was not publicly traded prior to the completion of this offering, we estimated the fair value of our common stock in 2019 and 2020. Our board of directors considers numerous objective and subjective factors to determine the fair value of our common stock as discussed in “Stock-Based Compensation Expense—Common Stock Valuations” below.

Expected Term: The expected term represents the period that our stock-based awards are expected to be outstanding and was calculated as the average of the option vesting and contractual terms, based on the simplified method. The simplified method deems the term to be the average of the time-to-vesting and the contractual life of the options.

Expected Volatility: Since we do not have a trading history of our common stock, the expected volatility was derived from the average historical stock volatilities of several public companies within our industry that we consider to be comparable to our business over a period equivalent to the expected term of the stock option grants.

Risk-Free Interest Rate: We base the risk-free interest rate on the implied yield available on U.S. Treasury zero-coupon issues with the remaining term equivalent to the expected term.

Expected Dividend: We have not issued any dividends in our history and do not expect to issue dividends over the life of the options and, therefore, have estimated the dividend yield to be zero.

The fair value of restricted stock units represents the estimated fair value of our common stock on the date of grant. For service-based awards, stock-based compensation is recognized using the straight-line attribution approach over the requisite service period. For performance-based awards, stock-based compensation is recognized based on graded vesting over the requisite service period when it is probable that the performance condition will be achieved.

Prior to the completion of this offering, given the absence of a public trading market for our common stock and in accordance with the American Institute of Certified Public Accountants Accounting and Valuation Guide, Valuation of Privately Held Company Equity Securities Issued as Compensation, our board of directors determined the best estimate of fair value of our common stock exercising reasonable judgment and considering numerous objective and subjective factors. These factors include:

Our board of directors determined the fair value of our common stock by first determining the enterprise value of our business, and then using that to derive a per share value of our common stock.

The enterprise value of our business was estimated by considering several factors, including estimates using the cost approach, market approach and the income approach. The cost approach estimates the fair market value of an organization by utilizing the balance sheet to take the total fair market value of assets minus the fair market value of liabilities. The market approach was estimated based on the projected value of comparable public companies in

a similar line of business that are publicly traded. We kept the comparable public companies consistent throughout each valuation. The income approach estimates the enterprise value of the business based on the cash flows that it expects to generate over its remaining life. These future cash flows are discounted to their present values using a rate of return appropriate for the risk of achieving the business’ projected cash flows. The present value of the estimated cash flows is then added to the present value equivalent of the residual value of the business at the end of the projected period to calculate the business enterprise value. In addition to the three approaches described above, we factor in the closest round of equity financing preceding the date of valuation.

After determining our enterprise value, we allocated value to our equity to determine the value of common stock. In allocating the enterprise value of our business to our common stock prior to January 2019, we used the option pricing method (“OPM”), whereas after January 2019, we used a combination of OPM and probability weighted expected return method (“PWERM”). PWERM involves a forward-looking analysis of the possible future outcomes of the enterprise. This method is particularly useful when discrete future outcomes can be predicted at a relatively high level of confidence with a probability distribution. Discrete future outcomes considered under PWERM include an initial public offering (“IPO”) of our common stock, as well as non-IPO market-based outcomes. Determining the fair value of the enterprise using PWERM requires us to develop assumptions and estimates for both the probability of an IPO liquidity event and stay private outcomes, as well as the values we expect those outcomes could yield.

A discount for lack of marketability (“DLOM”) is applied to arrive at a fair value of our common stock. A DLOM is meant to account for the lack of marketability of a stock that is not traded on public exchanges. In making the final determination of common stock value, consideration is also given to recent sales of common stock.

Application of these approaches involves the use of estimates, judgments and assumptions that are highly complex and subjective, such as those regarding our expected future revenue, expenses and future cash flows, discount rates, market multiples, the selection of comparable companies and the probability of possible future events. Changes in any or all of these estimates and assumptions, or the relationships between those assumptions, impact our valuations as of each valuation date and may have a material impact on the valuation of our common stock.

For valuations after the completion of our IPO, our board of directors will determine the fair value of each share of underlying common stock based on the closing price of our common stock as reported on the date of grant.

We provide standard assurance type warranties with our Voyager Trackers for periods generally ranging from five to ten years. We record a provision for estimated warranty expenses, net of amounts recoverable from manufacturers, to cost of sales when we recognize revenue. These estimates are based on our historical experience and forward-looking factors including the expected nature and frequency of product failure rates and costs to address future claims. These estimates are inherently uncertain given our relatively short history of sales and changes to our historical or projected warranty experience may result in material changes to our warranty reserve in the future. We do not maintain general or unspecified reserves; all warranty reserves are related to specific projects. All actual or estimated material costs incurred in subsequent periods are charged to those established reserves.

We are an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We intend to avail ourselves of this exemption from new or revised accounting standards. Accordingly, we will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies or that have opted out of using such extended transition period.

We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of customer concentrations and fluctuations in steel and aluminum prices. We do not hold or issue financial instruments for trading purposes.

Our customer base consists primarily of project developers, solar asset owners and EPCs. We do not require collateral on our accounts receivables. During the year ended December 31, 2019, three customers accounted for 59%, 21% and 13% of our total revenue, respectively. No other customers accounted for more than 10% of our total revenue. As of December 31, 2019, three customers accounted for 49%, 23% and 18% of our accounts receivable, respectively. No other customers accounted for more than 10% of our accounts receivable, respectively. During the year ended December 31, 2020, four customers accounted for 21%, 19%, 10% and 10% of total revenue, respectively. No other customers accounted for more than 10% of our total revenue. As of December 31, 2020, three customers accounted for 32%, 25% and 14% of accounts receivable, respectively. No other customers accounted for more than 10% of our accounts receivable.

Further, our accounts receivables are from companies within the solar industry and, as such, we are exposed to normal industry credit risks. We continually evaluate our reserves for potential credit losses and establish reserves for such losses.

We subcontract to various contract manufacturers, who manufacture and deliver products directly to our customers. We, therefore, do not procure raw materials and commodities directly. We are subject to indirect risk from fluctuating market prices of certain commodity raw materials, including steel and aluminum, that are used in our products, through our contract manufacturers, as increases in these commodity prices would increase our cost of procuring subcontracting services. Prices of these raw materials may be affected by supply restrictions or other market factors from time to time. Significant price increases for these raw materials could reduce our operating margins if we are unable to recover such increases in costs from our customers, and could harm our business, financial condition and results of operations.

Solar energy is the fastest growing form of electricity production today and is expected to account for approximately 35% of all new power plants installed globally between 2020 and 2025, the highest of any generation class, according to BNEF NEO. The global solar energy market is expected to grow to approximately $220 billion in size by 2026, at a CAGR of over 20% from 2019, according to a 2019 Allied Market Research report. Although the underlying photovoltaic cell technology used in solar energy production has existed for decades, efficiency improvements and cost reductions have accelerated the growth of the solar industry over the last decade. Solar energy costs have declined sharply in recent years, as evidenced by the 82% reduction in the global weighted-average LCOE of utility-scale solar energy between 2010 and 2019, according to a 2019 IRENA report. This compares to a 39% reduction in LCOE for onshore wind energy and a 29% reduction in LCOE for offshore wind energy over the same time period. LCOE represents the average cost per unit of electrical energy of building, financing, operating and maintaining a power plant over its operating life. As the global power sector transitions from reliance on fossil fuels towards renewable energy sources, solar, as an advanced, scaled and economical technology, is poised to increasingly benefit. Solar energy is expected to represent 23% of the global power generation mix by 2050, up from 4% today, according to BNEF NEO.

Solar energy capacity in the United States has increased at a 49% CAGR over the last decade and is expected to increase at a 16% CAGR through 2025, according to SEIA and BNEF NEO, driven by efficiency improvements and cost reductions, government incentives and regulations, such as investment tax credits and renewable portfolio standards, and demand for green energy by consumers, companies and other enterprises. Solar energy represented 40% of new energy capacity in 2019 according to SEIA and by 2050 is expected to represent 34% of U.S. power generation, up from 4% today, according to BNEF NEO. According to BNEF, utility-scale solar projects will benefit from the extension of clean energy tax credits. Forecasts suggest there will be 80 GW of new utility-scale solar installations in the United States between 2021 and 2025, according to a 2021 BNEF report. In contrast, forecasts suggest there will be only 43 GW of new onshore wind installations in the United States between 2021 and 2025, which also benefit from the extension of clean energy tax credits.

Solar energy capacity is growing outside of the United States as well, with the Middle East, Turkey and Africa (“META”), South-East Asia and Australia representing key areas of growth. The META region, historically known for its oil production, has strong solar resources and has made significant strides in the development of its solar energy market. BNEF NEO estimates that the META region will increase its solar installed capacity at a 30% CAGR between 2020 and 2025. South-East Asia’s solar energy market is driven by rapid economic growth, strong solar resources and energy security concerns related to the depletion of, and reliance on, fossil fuels. Australia has the highest solar radiation per square meter of any continent, according to Geoscience Australia, making it a region particularly conducive to solar energy generation. The continent has grown its installed capacity for utility-scale solar systems at a 97% CAGR between 2015 and 2019, and more than two-thirds of Australia’s renewable energy projects of this size commissioned in 2019 were solar, according to a 2020 Australia Clean Energy Council report.

Growth is also present in markets such as Europe and nations within Latin America and Sub-Saharan Africa. Europe, where the solar energy market has benefited from broad-based renewable energy policy support through initiatives such as the European Green Deal, represented 16% of global solar installed capacity in 2019 and is expected to grow its solar installed capacity at an 11% CAGR between 2020 and 2025, according to BNEF NEO. The solar energy markets in many countries within Latin America have benefited from increasing regulatory support, project auctions creating competitive pricing and favorable climate conditions for solar energy. This region grew from 2% of global solar installations in 2016 to 5% in 2018, according to a 2019 Wood Mackenzie report. Although still nascent, Sub-Saharan Africa’s growing demand for power, combined with a lack of current infrastructure to support traditional power sources and favorable climate conditions for solar energy, make the region a long-term growth opportunity for solar energy.

There are several key drivers of the robust growth outlook for the solar energy market globally:

Solar energy production is typically either roof- or ground-mounted, with each serving different end-users. Roof-mounted solar energy projects are typically smaller (under one MW) and built to serve one or a small number of end-users, while ground-mounted projects are typically larger (more than one MW) and built to feed electricity directly into the grid. Ground-mounted projects are expected to represent 82% of total solar energy installations in 2020 in the United States and to grow faster than roof-mounted projects through 2024, according to a 2020 Wood Mackenzie report and a 2020 IHS Markit report, respectively. Ground-mounted projects are usually constructed using either a fixed-tilt or a tracker-based system, with trackers enabling panels to rotate throughout the day to optimize perpendicular angular exposure to the solar radiation and as a result increase energy generation.

Trackers are rapidly gaining market share versus fixed-tilt mounting systems due to their ability to optimize energy production, accommodate more varied terrain and offer a more attractive return on investment. Typically, a tracker-based system (combined with advanced algorithms) yields, on average, 25% more energy and delivers approximately a 17% lower LCOE compared to fixed-tilt mounting systems, according to 2020 BNEF reports. The number of installations in the global solar tracker market expanded by 57% from 2018 to 2019, according to a 2020 IHS Markit report. Globally, tracker installations are expected to grow from 24 GW in 2019 to 44 GW in 2023, representing a CAGR of 17%. IHS Markit estimates that the tracker market globally generated $2.6 billion in revenue in 2020.

The United States currently represents the largest portion of the solar tracker market and is expected to grow from 8 GW in 2019 to 12 GW, and account for 48% of global installations, in 2020, according to a 2020 IHS Markit report. Between 2019 and 2023, the United States tracker market is expected to grow more than three times faster than the fixed-tilt tracker market. The United States has one of the highest levels of tracker market penetration, with 71% of new ground-mounted solar energy projects in 2019 electing to use trackers. IHS Markit estimates that the tracker market in the Americas generated $1.8 billion in revenue in 2020.

While the United States solar tracker market is expected to remain the largest market globally, the Middle East, Africa and Asia are expected to increase their share of the global solar tracker market. The Middle East and Asia, with tracker market penetration of 60% and 10% in 2019, respectively, are expected to grow their number of ground-mounted tracker installations at CAGRs of 41% and 18%, respectively, between 2019 and 2023. By 2023, the collective global share of tracker installations in these three regions is expected to reach approximately 40%, according to a 2020 IHS Markit report. Additionally, Europe is expected to grow its ground-mounted tracker installations at a CAGR of 11% during this same period. Meanwhile, the Americas (excluding the United States) region is expected to represent approximately 10% to 15% of global ground-mounted tracker installations between 2021 and 2023.

The growing awareness of tracker effectiveness, performance improvements and overall cost reductions have contributed to the growth of the global tracker market. Tracker producers have focused on both technological enhancements to maximize energy yield, as well as improved tracker model design to lower overall project expenditures by reducing installation time and complexity. For example, the integration of data analytics and machine learning technology in tracker systems has given operators further control over yield and cost optimization. Additionally, design enhancements have enabled trackers to be installed at sites that were previously uneconomical, including sites with uneven terrain, high wind zone areas and challenging soil environments. These factors contribute to a lower lifetime cost of ownership, 17% lower LCOE and 25% higher energy yield for solar energy systems utilizing trackers instead of fixed-tilt systems, according to BNEF.

This declining cost trend is coupled with a rising proportion of solar asset owners and project developers making design decisions around (and in many cases, directly purchasing) solar energy equipment, such as tracker systems and technology. Traditionally, EPC contractors have outfitted solar projects with the technologies of their choosing and have been less incentivized to make decisions to optimize production and cost of ownership, which are long-term factors. As solar asset owners and project developers become more involved with the buildout of their projects, including selection of solar energy equipment, lifetime cost of ownership becomes a larger focus in the selection process, which benefits producers of tracker systems.

There are several key design innovations that differentiate the solar panel and tracker systems currently on the market:

We are a global provider of advanced solar tracker systems, supported by proprietary software and value-added engineering services. Our mission is to provide differentiated products, software and services that maximize energy generation and cost savings for our customers, and to help facilitate the continued growth and adoption of solar power globally. Trackers significantly increase the amount of solar energy produced at a solar installation by moving solar panels throughout the day to maintain an optimal orientation relative to the sun. The combination of integrated hardware tracking technology and advanced software algorithms in solar tracker systems yields, on average, 25% more energy and delivers a 17% lower LCOE compared to fixed-tilt mounting systems, according to 2020 BNEF reports. Our systems offer efficiency gains relative to other tracker systems due to our tracker’s enhanced design, which includes a two-panel in-portrait format and independent rows, and its optimization for use with bifacial panels. Additionally, these efficiency gains can be enhanced by our proprietary software solutions. Our customers include leading project developers, solar asset owners and EPC contractors that design and build solar energy projects. Our team of experienced renewable energy professionals is focused on delivering compelling value to customers across the full solar energy project lifecycle, including at the development, construction and operations phases.

Voyager is a next-generation two-panel in-portrait single-axis tracker solution that we believe offers industry-leading performance and ease of installation. With our Voyager offering, we are one of the largest providers of two-panel in-portrait trackers in the United States, which we determined based on our estimated U.S. tracker market share of approximately 11% (which was calculated using our MW shipped for fiscal year 2020 compared to a total tracker market shipment estimate from a 2020 Wood Mackenzie report). We designed Voyager to reduce construction costs by enabling efficient use of land, maximizing site accessibility and reducing materials needed for construction. Additionally, Voyager’s patented panel connection features are designed to optimize speed of installation and reduce assembly labor. Due to these design and installation benefits, we believe Voyager offers industry-leading installation cost per watt compared to competing trackers. Post-installation, owners of solar energy projects benefit from Voyager’s proprietary control system, which employs advanced adaptive tracking algorithms that improve production and site yield. We also offer a software solution, SunPath, which uses proprietary algorithms that take into consideration topography, meteorological conditions and other local site conditions to further optimize tracking and help produce additional energy yield over our base-model Voyager Trackers.

Our global market opportunity is driven by two primary factors: overall growth in utility-scale solar projects and the increased usage of trackers as the preferred mounting system in utility-scale solar projects. Solar energy is the fastest growing source of electricity globally due to declining costs of production, increased efficiency, commitments by companies and utilities to use low-carbon energy (including as part of social responsibility efforts), as well as policy support from foreign, federal and local governments and regulators. By 2050, solar energy is expected to account for 23% of the global power generation mix, up from 4% today, according to BNEF NEO. Annual solar PV installations have more than doubled from 50.5 GW in 2015 to 109 GW in 2019, and are expected to grow to 145 GW of installations annually by 2025, according to a 2020 Wood Mackenzie report. Within the growing solar energy market, trackers are rapidly gaining market share versus fixed-tilt mounting systems due to their ability to optimize energy production, accommodate more varied terrain and offer a more attractive return on investment. Globally, tracker installations are expected to grow from 14 GW in 2018 to 41 GW in 2025, according to a 2020 Wood Mackenzie report, representing a CAGR of 16%. North America currently represents the largest portion of the solar tracker market and is expected to account for 50% of global installations in 2020, growing from 8 GW in 2019 to 14 GW in 2020. In terms of tracker market penetration, North America and Latin America have the highest levels, with 84% and 87%, respectively, of new ground-mounted solar energy projects in 2019 in each region electing to use trackers. The Middle East and Africa, Europe and the Asia Pacific regions present significant growth opportunities as tracker penetration increases in such markets.

Our company was formed in 2017 by a group of renewable energy industry veterans, including the team with substantial experience deploying the AP90 tracker, a first-generation one-panel in-portrait, linked-row design tracker system. The AP90 tracker was first installed in 2013, and achieved approximately 900 MW of cumulative global installations between 2013 and 2016, prior to our formation. Our management team utilized their design and construction expertise, and their experience installing and operating other competitive tracking solutions, to design and develop a next-generation tracker system, Voyager, which achieved product certification in 2019. As of December 31, 2020, we had $109 million of executed contracts and awarded orders for Voyager , reflecting a 102% increase over the same amount as of December 31, 2019. From the period January 1, 2021 to April 14, 2021, we had an additional $227 million of executed contracts and awarded orders for Voyager, for a total of $336 million (which includes revenues not yet reported for Q1 of 2021). Of the $336 million, approximately $187 million worth of products has shipped or has an anticipated shipment date in 2021. We define executed contracts and awarded orders as orders that have been documented and signed through a contract or where we are in the process of documenting a contract but for which a contract has not yet been signed. These amounts do not represent GAAP revenue, and if and when these orders are fulfilled by us will be subject to our revenue recognition policy as described in the Notes to our Consolidated Financial Statements.

In addition to conducting internal quality control procedures, we have engaged and received testing and inspection certifications from several organizations including Black & Veatch, DNV GL, Enertis and RWDI to help validate the quality of our operations and product offerings.

Our corporate headquarters is located in Austin, Texas and we have a training and technology development site in Aurora, Colorado. To assist with our global expansion effort, we have grown our sales and support network abroad, with employees located in Australia, India, the Middle East, China and South-East Asia as of December 31, 2020.

Voyager is built upon a self-powered, two-panel in-portrait design utilizing a 60-meter independent row architecture, which provides numerous advantages to our customers, including:

We believe that the following strengths provide us with a competitive advantage and position us to capitalize on the continued growth of the solar energy and tracker markets:

We intend to grow by:

We seek to establish market leadership through generating attractive returns and driving customer value with our solar tracker systems and software solutions. Our core values of integrity, accountability, innovation and excellence are central to the way in which we do business. We act with integrity by holding ourselves to the highest legal, ethical and moral standards in every business decision we make. We believe that accountability to our customers and our commitment to meeting their business needs will continue to drive deep long-term relationships. Innovation is at the core of our business as we continuously strive to improve our products, services and processes. We are committed to delivering excellent results at every stage of the solar energy project lifecycle, and we relentlessly drive to improve the quality of our products and services.

Additionally, we recognize the importance of environmental stewardship, cultivating sustainable relationships with our employees, manufacturers and the communities where we operate, and accountability of our leadership to our stakeholders. As a renewable energy company, we are passionate about our role in facilitating the global transition away from fossil fuel energy sources and towards renewable energy sources. We intend to continue building our business and shaping our corporate culture by taking into account ESG principles applicable to our company. For example, we have received International Standards Organization (“ISO”) 14001:2015 environmental management system certification and ISO 9001:2015 quality management system certification at our corporate headquarters. ISO 14001:2015 and ISO 9001:2015 are globally recognized standards for environmental and quality management systems that provide a voluntary framework to identify key environmental and quality aspects within businesses. We are currently applying for ISO’s Occupational Health and Safety Management certification, ISO 45001:2018. Our contract manufacturing partners also undergo a qualification process to remain on our approved vendor list, which includes a review and assessment of their environmental performance. See “Our Business – Our Manufacturing and Supply Chain” below.

Electricity generation from fossil fuel sources results in a significant amount of greenhouse gas and particulate matter emissions, and our offering as a renewable solar energy-based solution helps mitigate this impact by acting as a replacement for such polluting sources. Our 1.9 GW of installed capacity represents the elimination of 3.3 million tons of carbon dioxide, 2,457 tons of sulfur dioxide, 2,602 tons of nitrous oxide and 232 tons of particulate matter under 10 microns of emissions from electricity generation in the United States in 2019, according to data provided by the United States Energy Information Administration and Environmental Protection Agency. As we grow our business, we recognize the continued impact our product offering will have on the reducing the overall emissions of electricity generation around the world.

The additional energy yield SunPath can provide to our customers and owners of solar energy projects depends on the specifics of the site where it is implemented. SunPath consists of two primary algorithms:

We have several additional features of SunPath under various stages of development and implementation. We intend to continue to develop the features of the SunPath software to further maximize the energy output of Voyager Trackers utilizing the SunPath software, contributing to increased efficiency gains over our base-model Voyager Trackers.

We currently offer tracking and software solutions targeting the utility-scale solar energy markets to current and potential customers in the United States, Asia, the Middle East, North Africa and Australia, and we aim to continue to expand our global footprint in Latin America and Europe.

Of our approximately 140 tracker, software and engineering services customers, our primary ones are located in existing markets and include project developers, solar asset owners and EPC contractors. We also work closely with other project-level stakeholders, including independent engineers, project lenders, tax equity providers, insurers and mechanical subcontractors. Solar tracker procurement for utility-scale solar energy projects is often the responsibility of either the EPC contractor or the project developer, depending on the structure of the project. As a result, our largest customers are EPC contractors that construct multiple projects for many developers. As project development becomes more competitive, however, project developers and solar asset owners are increasingly purchasing Voyager directly and relying on EPC contractors for installation. In 2019, approximately 64% of our revenue (excluding revenue attributable to software sales) was attributable to EPC contractors and 36% to project developers, while in 2020, approximately 50% of such revenue was attributable to EPC contractors and 50% to project developers. We expect our revenue profile to continue to trend more toward project developers in the future. Our two largest customers collectively accounted for approximately 80% of our revenue in 2019 and 40% of our revenue in 2020. As a result of this heavy reliance on existing customer referrals, the pre-sales and post-sales process is deeply focused on execution and customer satisfaction.

We work with many of the leading EPC contractors and project developers in the United States. Our customers currently represent 60% of the top 15 EPC contractors in 2019-2020 in terms of MW installed. A key element of our sales and marketing strategy is establishing and maintaining close relationships with our customers. We are seeking to deepen these relationships through master supply agreements or multi-year procurement contracts with our customers for the purchase of larger volumes of solar trackers. For example, our largest customer in 2019 was an EPC contractor that used the trackers it purchased in multiple solar energy projects for three different project developers.

Our sales and marketing strategy is focused on clear communication with and education of all necessary stakeholders involved in the financing, procurement, construction and operation of the solar asset to whom we are providing our products and services, with the objective of positioning Voyager as the market leading two-panel in-portrait solution for global utility-scale solar energy projects. We interface and engage with new customers through a combination of direct marketing and sales efforts, training and education, including by providing independently-

sourced reporting materials, and sponsorship of industry conferences and events. These efforts are closely tied to the sales cycle of Voyager, producing core deliverables and messaging at each step of the sales process. For our customers that are project developers and solar asset owners, we emphasize the total cost of ownership of a Voyager Tracker and, for our customers that are EPC contractors, we emphasize our lean construction methodologies, logistics tracking and management, and installation cost savings.

Our current marketing channels for new customers consist of leveraging existing references for new business (for example, existing EPC contractor customers introducing us to project developers and solar asset owners and vice versa), industry conferences and events, request for proposals, in-person training, press releases, our website and our social media presence. As a result, the sales process primarily revolves around direct customer proposals and engagement, targeted marketing campaigns and participation in request for proposals. The sales cycle with our customers typically ranges from one to six months. We plan to expand our marketing efforts through webinars, global publications, installation training videos and participation in industry groups.

In addition, we believe that the significant and continued growth in our installed base of Voyager Trackers creates opportunities to sell additional products, software and services that are related to, and provide operational enhancements for, Voyager Trackers. Our strategy is to introduce a targeted set of offerings over time (similar to the SunPath offering that was released in the fourth quarter of 2020), including hardware and software upgrades and retrofits, as well as preventative maintenance services and extended warranty plans, each of which we believe can generate high margin, recurring revenue.

Our sales team is incentivized to sell Voyager Trackers and services through a standardized commission program. All sales activities are meticulously logged in Salesforce to accurately track and monitor near- and long-term project pipeline.

As of December 31, 2020, our sales and marketing organization included 13 employees in 6 countries. In the United States, Asia, the Middle East, North Africa and Australia, our tracker technology, software and engineering services are actively being marketed by our sales team.

We plan to continue increasing our presence in the United States, as well as expanding globally. Since our inception, we have sold our tracker products to customers located in North America, Australia, Europe and Asia, although historic sales of Voyager Trackers have been heavily concentrated in the United States. In 2021, we have been awarded orders in Australia.

Our training and customer support team is led by veterans of the utility-scale renewable energy industry having multiple GW of solar experience across the value chain from green field development through lean construction execution, culminating in operations and maintenance. With our experience and expertise in solar PV utility-scale construction, our customers rely on us as a thoughtful partner who will put the needs of the project first and use the problem-solving techniques we have developed through our collective experience to individualize and optimize customer solutions.

Our dedication to training and customer support transcends the traditional supplier transactional relationship. We strive to bond with our customer project teams, offering our customers the opportunity to attend our hands-on, multi-day “Voyager Certification” training hosted at our Aurora, Colorado technology development site that focuses on assembly techniques, construction methods, crew size and work flow optimization to enable our customers to achieve exceptional on-site execution. Following the Voyager Certification training, we currently enable all of our customers to elect to have us travel to the customer site and provide another hands-on, multi-day installation training with our customers’ contractors or subcontractors, which ensures that solar construction best practices enabled by Voyager’s design are recognized and practiced.

During “cold-commissioning,” which occurs after a customer’s array panels are installed but prior to energization, we currently offer a dedicated team for a multi-day training on our commissioning and distill commissioning activities down to a “plug and play” familiarity in a manner that provides automatic progress updates to an executive dashboard in real time. This process increases visibility and the “cold-commissioning” process allows for additional hands-on experience with Voyager’s system, providing customers with testing and troubleshooting tools early in the life-cycle of the project.

Lastly, the owner of the project can benefit from the operations and maintenance training that we offer, where we walk them through basic operations, simple on-site repairs and troubleshooting, as well as introduce them to our request for information system, which has been widely commended by our customers. This training ensures that customers have access to the tools to operate their solar project successfully and the means to escalate an issue, should help be required.

We have designed a multi-regional, diversified supply chain, supported by our contract manufacturing partners. This approach is designed to minimize material movement and maximize delivery of large product volumes globally. Our global supply chain professionals have a combined 150 years of experience at leading solar energy companies with global supply chains. Our supply chain team is integrated into our processes during design and manages material flow and customer communication through delivery to project sites.

Innovation is a core value of our company. We invest substantially in research and development (“R&D”) to enhance and expand our product and services portfolio and to drive value to our customers by improving site yield, reducing total installation cost and improving installation speeds. We implement a rigorous process to evaluate new initiatives, define and measure market opportunities and assess program value, before launching a structured phase-gate process for new product and services introduction.

As of December 31, 2020, our R&D department accounted for approximately 24% of our headcount. 95% of these employees hold engineering or science degrees and 39% of these employees also hold either a master’s degree or a PhD. Our R&D team has expertise and industry experience in structural design, civil engineering, software and electronics engineering and communication networks. We also work with third party industry experts for product validation, performance testing and certification of new products.

The protection of our technology and intellectual property is an important aspect of our business. We seek to protect our intellectual property rights through patent, trademark, copyright and trade secret laws, as well as through confidentiality agreements and non-disclosure agreements. We generally enter into confidentiality and invention assignment agreements with our employees and independent contractors to control access to, and clarify ownership of, our proprietary information. We have also entered into agreements with third parties, including with respect to one

third party an exclusive license agreement, pursuant to which we received certain rights to use the intellectual property of those third parties. We also require other third parties who may have access to our proprietary technologies and information to enter into non-disclosure agreements.

As of December 31, 2020, we had one U.S. trademark registration, five U.S. applications for trademark registration, 45 issued U.S. patents, nine issued non-U.S. patents, six patent applications pending for examination in the United States and nine patent applications pending for examination in other countries related to panel attachments, solar tracking algorithms, related design and assembly methods, and software solutions. As of December 31, 2020, we believe that Voyager and SunDAT are covered by certain of our issued or pending U.S. and non-U.S. patents and patent applications, and that we have other issued or pending U.S. and non-U.S. patents and patent applications that may contain claims that could be practiced by our current or planned products. Our issued U.S. patents are expected to expire between 2022 and 2039.

Federal, state, local and foreign government bodies provide incentives to owners, end-users, distributors, system integrators and manufacturers of solar energy systems to promote solar electricity in the form of rebates, tax credits and other financial incentives such as system performance payments, payments of renewable energy credits associated with renewable energy generation and an exclusion of solar energy systems from property tax assessments. The market for grid-connected applications, where solar power is sold into organized electric markets or pursuant to power purchase agreements, often depends in large part on the availability and size of these government subsidies and economic incentives, which vary by geographic market and from time to time. The following is a summary of certain major current government subsidies and economic incentives that our customers and owners of solar energy projects may take advantage of.

The most notable incentive program to our U.S. business is the ITC for solar energy projects, which allows taxpayers to offset their federal income tax liability by a certain percentage of their cost basis in solar energy systems placed in service for commercial use. Under existing tax law, the ITC is 30% for projects that began construction prior to 2020 and are placed in service before 2024, and is reduced to 26% for projects that began construction in 2020, 2021 or 2022 and are placed in service before 2026, to 22% for projects that began construction in 2023 and are placed in service before 2026 and to 10% for projects that began construction after 2023 or placed in service after 2025 regardless of when construction began.

The year in which the solar energy project is deemed to have begun construction is the relevant year for determining the applicable ITC rate under the U.S. Internal Revenue Service (“IRS”) rules. The IRS rules provide that construction begins in the year in which a taxpayer either (i) commences physical work of a significant nature on the project site or on a project equipment or (ii) pays or incurs at least 5% of the total qualifying project cost of the solar energy project (the “5% Safe Harbor”). Under the 5% Safe Harbor, the taxpayer may choose to satisfy the requirement by purchasing equipment, and the IRS rules generally require that the taxpayer receive delivery of the purchased equipment within three and a half months after payment.

RPSs are another set of policies designed to increase the use of renewable energy sources for electricity generation. In the United States, 30 states and the District of Columbia have implemented RPSs, which require a specified percentage of the electricity sold by utilities to come from renewable resources by a certain date. While many state targets are between 10% and 45%, 14 states have targets of 50% or greater.

A feed-in-tariff (“FiT”) is another type of incentive that pays owners of renewable energy systems, including solar energy systems, a certain amount per unit of electricity they generate and provide to the grid. These incentives are often at above-market fixed-prices that are locked in over contract periods of 10 to 20 years. The key difference between FiTs and other solar energy incentives, such as the ITC, is that FiTs are based on the amount of electricity produced in a given solar energy system, as opposed to being based on the amount of money invested in a solar energy system. While FiTs are relatively rare as a solar policy mechanism in the United States (with only a handful of states offering them), they are more common internationally.

Additional renewable energy incentives may exist in or be developed inside or outside of the United States which could benefit us as we expand our business. As our international sales grow and our global footprint expands, our customers and owners of solar energy projects may have access to incentives for solar energy projects, such as FiTs, tax deductions and grants toward equipment purchases. For example, Vietnam has adopted corporate income tax regulations that provide a preferential tax rate for income from investment in the production of renewable energy, clean energy and waste-to-energy process.

Our revenue may be impacted by seasonality and variability related to ITC step-downs and construction activity. We expect customer purchasing to be impacted by ITC step-downs and project construction activity in the United States and the rest of the world is lower in colder months depending on geographic location. Given that the installation of Voyager Trackers requires setting foundations in the ground, it is more costly to our customers to install trackers when the ground is frozen. As a result, depending on the timing of revenue recognition, both these factors could impact our total revenue from one period to another. We expect our total revenue to continue to be impacted by these factors (i) in the case of the ITC step-downs, once they resume after 2022 and until they cease in 2024 and (ii) in terms of seasonality related to cold weather months, until our expansion into areas with traditionally warmer climates results in less pronounced seasonal variations in our revenue profile.

The tracker industry is highly specialized and dominated by a relatively small number of companies. Our direct tracker competitors include Array Technologies, Inc. and NEXTracker Inc. We also compete indirectly with manufacturers of fixed-tilt mounting systems. We compete on the basis of product performance and features, total cost of ownership (usually measured by LCOE), reliability and duration of product warranty, sales and distribution capabilities, training and customer support.

As of December 31, 2020, we had 178 full-time employees. Of these employees, 43 were engaged in R&D, 13 in sales and marketing, 90 in operations and support and 32 in general and administrative capacities. Of our employees, 108 were based in the North America, 67 were based in Asia, of which three were based in China, one was based in the Middle East and two were based in Australia. None of our employees are represented by a labor union. We have not experienced any employment-related work stoppages, and we consider relations with our employees to be good.

Our human capital resources objectives include, as applicable, recruiting, retaining, incentivizing and integrating our existing and future employees. Our compensation program is designed to attract, retain and motivate highly qualified employees and executives. We use a mix of competitive base salary, performance-based equity compensation awards and other employee benefits. The health and safety of our employees are of primary concern. During the COVID-19 pandemic, we have taken significant steps to protect our workforce including but not limited to, working remotely when feasible and implementing social distancing protocols consistent with guidelines issued by federal, state and local governments.

Our corporate headquarters is located in Austin, Texas, in an office consisting of approximately 5,181 square feet of office space. We have a lease on our corporate headquarters, which expires on August 31, 2023.

In addition to our corporate headquarters, we lease approximately 5,300 square feet of warehouse space and 1,100 square feet of sales and support office space in Brendale, Australia and 2,500 and 2,860 square feet of sales and support office space in Hyderabad and Bangalore, India, respectively. We are also a member of SolarTAC, a collaborative research facility aimed at advancing proprietary and collaborative research projects to support the growth of individual solar energy companies as well as the solar industry as a whole. Through our SolarTAC membership, we have access to a development sandbox of 174,240 square feet in Aurora, Colorado that we primarily use for customer training, product development and certification.

We outsource all manufacturing to contract manufacturing partners and currently do not own or lease any manufacturing facilities.

We believe that our existing properties are in good condition and are sufficient and suitable for the conduct of our business for the foreseeable future. To the extent our needs change as our business grows, we expect that additional space and facilities will be available.

From time to time, we are subject to routine legal proceedings in the normal course of operating our business. As of the date of this prospectus, we are not involved in any material legal proceedings.

On April 21, 2021, FCX Solar, LLC (“FCX”), filed a lawsuit against us in the United States District Court for the Southern District of New York. The complaint alleges breach of contract and other claims related to a patent license agreement and consulting relationship between FCX and us. FCX seeks damages of approximately $133 million in the claim. We believe we have strong defenses to the claim, and we plan to vigorously defend against it. However, the outcome of any legal proceedings is inherently uncertain, and any judgment, ruling, fine, penalty, or injunctive relief entered against us or any adverse settlement could negatively affect our business, results of operations, and financial condition.
