Item 1. Business

Overview

We are a leading global provider of solar tracking technology and fixed-tilt systems to utility-scale and distributed generation customers who construct, develop, and operate solar photovoltaic (“PV”) sites. With solutions engineered to withstand harsh weather conditions, Array’s high-quality solar trackers, fixed-tilt systems, software platforms, foundation solutions, and field services combine to optimize energy production and deliver value to our customers for the entire lifecycle of a project.

Our principal products are a portfolio of integrated solar tracking systems comprised of software and hardware that include, for example, component parts such as steel tubing, steel supports, drivelines, center structures, electric motors, motor controller assemblies, bearing assemblies, gearboxes and electronic controllers commonly referred to as a single-axis “tracker.” Trackers move solar panels throughout the day to maintain an optimal orientation to the sun, which significantly increases their energy production. Solar energy projects that use trackers typically generate more energy and deliver a lower Levelized Cost of Energy (“LCOE”) than projects that use “fixed tilt” mounting systems, which are stationary. The vast majority of ground mounted solar systems in the U.S. use trackers; however, there are certain situations where fixed-tilt solutions are preferred.

Our flagship tracker uses a patented design that allows one motor to drive multiple rows of solar panels through articulated driveline joints, which typically leads to lower assembly costs and lower ongoing operating and maintenance costs. To avoid infringing on our U.S. patent, our competitors must use designs that we believe are inherently less efficient and reliable. For example, some of our competitors’ designs require one motor for each row of solar panels. As a result, we believe our products have greater reliability, lower installation costs, reduced maintenance requirements and competitive manufacturing costs. Our core U.S. patent on a linked-row, rotating gear drive system does not expire until February 5, 2030.

With our acquisition of Soluciones Técnicas Integrales Norland, S.L.U., a Spanish private limited liability company, and its subsidiaries (collectively, “STI”) in January 2022, we added a dual-row tracker design to our product portfolio. The Array STI H250 tracker uses one motor to drive two connected rows and is ideally suited for sites with irregular and highly angled boundaries or fragmented project areas. To offer a comprehensive set of solutions to the growing market, in September 2022, we also introduced a third tracker product, OmniTrack, which requires significantly less grading and civil works permitting prior to installation and accommodates uneven terrain. This suite of products extends our target applications and ability to deliver what we believe are the best utility-scale solar tracker solutions to the market.

APA Acquisition

On August 14, 2025 (the “Closing Date”), our wholly owned subsidiary STINorland USA, Inc., a California corporation (“Buyer”), completed the acquisition of 100% of the issued and outstanding equity interests of APA (the “APA Acquisition”), pursuant to the terms of the equity purchase agreement, dated as of June 17, 2025 (as amended, the “Purchase Agreement”), by and among the Company, Buyer, APA, SunHoldings, LLC, an Ohio limited liability company (“Seller”), and the guarantors party thereto. The total purchase consideration for the APA Acquisition totaled approximately $185.4 million.

APA designs, engineers, and manufactures solar racking, mounting and foundation systems. Integrating such systems into our business model through the acquisition of APA expands our product portfolio to better serve the evolving needs of the solar industry and our customers.

Industry Overview

Solar energy has emerged as one of the fastest growing forms of renewable energy and represents one of the most attractive long-term investment opportunities within the global energy transition. Global energy demand is rising as transportation, heating, and industrial processes continue to electrify, while digital infrastructure and artificial intelligence (“AI”)-driven data center expansion further increase power consumption. Solar is positioned to capture a significant share of incremental generation capacity due to its scalability, speed to deploy, and broad geographic applicability. In many regions, solar is one of the lowest-cost sources of new energy generation, making it economically attractive even without policy incentives. This cost advantage continues to drive widespread adoption across distributed generation and utility-scale markets. Despite strong growth in recent years, solar still represents a relatively modest portion of global power generation, providing meaningful runway for continued expansion.

Sales

Our Customers

We sell our products to solar developers, independent power producers, utilities, and EPCs that build solar energy projects, often under master supply agreements or multi-year procurement contracts. Although sales to a single customer may occasionally be greater than 10%, they generally represent multiple projects, each independently financed, for many different end customers who often directly influence or make the decision to use our solar tracking systems.

During the year ended December 31, 2025, we derived 81% and 19% of our revenues from customers in the U.S. and the rest of the world, respectively. From the founding of Array through December 31, 2025, we had shipped more than 96 gigawatts of trackers to customers worldwide.

Our Offerings

Tracker Systems

Large-scale solar energy projects are typically laid out in successive “rows” that form a “block.” A solar array can have dozens of rows with more than 100 solar panels in each row. With a single-axis tracker system, motors and gears cause each row of solar panels to rotate along their north-south axis to continually align the row with the sun throughout the day. Different tracker manufacturers use different approaches to rotate the panels in a row. We have a variety of tracker systems that, depending on the project site characteristics, offer customers a differentiated set of benefits.

DuraTrack® HZ v3

Our flagship product is the DuraTrack® HZ v3 tracker system (“DuraTrack®”), which we launched in May 2015. DuraTrack® is our third-generation single-axis tracker and includes unique patented features such as a patented single-bolt per module mounting system that reduces installation time, a passive wind load mitigation system and a low number of motors and controls per megawatt (“MW”).

Array STI H250

The Array STI H250 tracker system is designed to deliver a favorable LCOE with a robust, dual-row tracker system. The design enables one motor to move up to 120 PV modules making this an efficient utility-scale solar tracking system ideally suited for sites with irregular boundaries, highly angled blocks, or fragmented project areas. During the fourth quarter of 2025, the Company approved a plan to phase out a version of the

H250 product that was not compatible with SmarTrack® in order to focus on a SmarTrack®-compatible version introduced in 2024.

Array OmniTrack

The Array OmniTrack tracker system (“OmniTrack”) delivers all the benefits of our flagship product DuraTrack® — high reliability, durability and performance — with the added benefits of enhanced north/south terrain flexibility and minimized grading. OmniTrack’s flexible design allows for installation on unlevel site terrain, accommodating a greater slope and requiring significantly less grading and civil works, which reduces project costs and improves installation timelines for our customers.

Array SkyLink

The Array SkyLink tracker system (“SkyLink”) features a PV-powered control system that operates independently from the grid. This ensures that solar trackers can still stow during hail or snow accumulation, as detected by Array SmarTrack® Automated Snow Response software and Array SmarTrack® Automated Hail Alert Response software. Additionally, its passive wind stow technology protects solar installations without relying on battery power in low temperatures. SkyLink’s wireless technology reduces the need for wiring and eliminates the need for trenching, which reduces project costs and improves installation timelines for our customers.

Array SmarTrack® Software

Array SmarTrack® is our range of software and control-based products designed to optimize energy production and mitigate the risk of extreme weather events for utility-scale solar sites. Array SmarTrack® Diffuse Weather Response software uses real-time weather data it continuously receives from an on-site global horizontal irradiance sensor to optimize energy capture during cloudy or overcast sky conditions, while Array SmarTrack® Terrain Adaptive Backtracking software adjusts tracker angles to optimize energy production and reduce row-to-row shading during periods of low sun height and on sites with sloping terrain. Array SmarTrack® Automated Hail Alert Response software utilizes reliable third-party weather data, in combination with unique patented algorithms, to identify the optimal position for a solar array in real time to protect the solar investment from the unpredictability of hailstorms and mitigate risk of hail damage to the system. Array SmarTrack® Automated Snow Response incorporates ultrasonic snow sensors to rotate trackers to their maximum stow position to allow snow to slide off the face of the PV modules. This helps to prevent snow accumulation and reduces the effective snow load on the system. Equipped with the Array SmarTrack® controller, the system is designed to adapt to unique site terrain and weather conditions, improving project yield and reducing risks in extreme weather, while simplifying operations and maintenance (“O&M”) practices.

Foundation Solutions

As a result of the APA Acquisition, we strengthened our product portfolio by introducing Array APA Foundation Solutions, a comprehensive range of solar foundation systems designed to support utility-scale solar projects across diverse and challenging soil conditions. This offering includes advanced foundation technologies such as ground screws for rocky soils, helicals for soft soils, c-piles for ideal soils, and ballast for impenetrable soils. Array APA Foundation Solutions not only enhances installation efficiency and reduces overall project costs but also improves long-term reliability and reduces environmental impact.

Racking Solutions

Our racking product portfolio provides solutions for both the fixed‑tilt and tracker markets, with a focus on utility-scale projects. These systems are engineered to perform across a wide range of site conditions. With modular designs engineered for durability, constructability, and compatibility across various project

environments, our racking solutions give customers a versatile platform that can be tailored to the unique characteristics of each site.

APA Titan

Array APA Titan features an adaptable solar rack design that allows for flexibility in the field while streamlining installation. Its four-rail design is an excellent solution for areas with high snow loads and large format modules, delivering strength and reliability for utility-scale projects.

APA A-FrameTM Interface

APA A-FrameTM Interface is a dual-post tracker foundation designed for challenging terrain and frost-prone soils. Its patented A-frame design distributes loads efficiently, reducing material requirements and installation depth while mitigating frost heave risk. Compatible with major tracker brands and supporting helical or ground-screw foundations, the system offers up to 30″ of field adjustability for uneven terrain, simplifying installation and reducing grading.

APA Titan DuoTM

APA Titan DuoTM features a 4-rail design for areas with high snow loads and large format modules. Titan DuoTM comes standard with dual ground screws. Its two-high module configuration reduces the number of foundation posts and overall material requirements, streamlining installation and lowering costs.

We have field service engineers located in geographies where we are active, to support our customers with the commissioning of large projects, introduction of new technologies and features, and on-the-job training for new installers.

Competition

Trackers are highly specialized products that are specific to the solar industry. The unique expertise required to design trackers, and customers’ reluctance to try unproven products, have confined the number of firms that produce trackers to a relatively small group. Our principal tracker competitors include Nextpower Inc. (f/k/a Nextracker, Inc.), PV Hardware and GameChange Solar. We also compete with manufacturers of fixed-tilt mounting systems and engineered foundations, including UNIRAC, Inc. and Terrasmart (f/k/a RBI Solar Inc.), a subsidiary of Gibraltar Industries, Inc. We compete based on product performance and features, total cost of ownership (usually measured by LCOE), reliability and duration of product warranty, sales and distribution capabilities and training and customer support.

Resources

Manufacturing

In the U.S., we operate an approximately 283,000 square foot manufacturing facility in Albuquerque, New Mexico. Our manufacturing process is designed to meet four objectives: (i) limit capital intensive and low value-added activities that can be outsourced to other companies; (ii) minimize labor content where possible; (iii) minimize the amount of assembly our customers will be required to do at the site; and (iv) minimize material movement both from vendors to us and inside our factory. In connection with the APA Acquisition, the Company has lease agreements for offices, manufacturing facilities and warehouses located in Ohio and Connecticut. Of these lease agreements, five are with related parties owned by certain members of APA’s management team.

In May 2024, we entered into a triple-net lease for a new manufacturing and office facility located in Bernalillo County, New Mexico, which includes approximately 176,000 square feet of manufacturing space and approximately 40,000 square feet of office and laboratory space. We took control of the facility in the fourth quarter of 2025 and construction is expected to be completed in March 2026. We expect to commence production at the facility in the first half of 2026.

Internationally, with our STI Operations reporting segment, we have approximately 67,000 and 610,000 square feet of manufacturing and warehouse facilities in Spain and Brazil, respectively. These locations support manufacturing and assembly of component parts for both local and international markets.

We produce and/or assemble module clamps, center structures, and motor controller assemblies at our Albuquerque facility. We have entered into outsourcing contracts for steel tubing, steel supports, drivelines, bearing assemblies, gearboxes, electric motors and electronic controllers that ship directly from our suppliers to job sites or designated warehouses. By using vendors, we are able to drop-ship products directly to our customers’ sites, which improves working capital turnover, quality and inventory management.

While we have historically maintained certain levels of supplies and inventories manufactured by outside vendors, we have the capability to manufacture internally some of these products at our principal manufacturing facility located in Albuquerque, New Mexico. Additionally, we have identified certain alternative vendors for efficiency and redundancy purposes.

We believe our Array Legacy Operations (as defined below) segment’s status as a U.S.-based company with domestic manufacturing reduces the potential impact of U.S. government tariffs or other U.S. government regulatory actions taken against, products manufactured in foreign countries and imported into the U.S.

Research and Development

We devote resources to research and development (“R&D”) with the objective of developing innovative new products and services that enhance system performance, improve product reliability, reduce product cost and simplify installation. Our development strategy is to identify features that bring value to our customers and differentiate us from our competitors. We strive to address customer pain points and needs. We measure the effectiveness of our R&D using a number of metrics, beginning with a market requirements definition, which includes a program budget, financial payback, resource requirements, and time required to launch the new product, system, or service into the market. We employ a stringent engineering phase gate review process that ensures all R&D programs meet their stated objectives from inception to deployment.

We have a strong R&D team with significant experience in solar energy as well as expertise in mechanical engineering, software engineering, civil engineering, and systems/control engineering. As needed, we collaborate with academic institutions, national laboratories and consultants, to further enhance our capabilities and confirm results independently.

Intellectual Property

The success of our business depends, in part, on our ability to maintain and protect our proprietary technologies, information, processes and know-how. We rely primarily on patent, trademark, copyright and trade secret laws in the U.S. and similar laws in other countries, confidentiality agreements and procedures and other contractual arrangements to protect our technology. As of December 31, 2025, we had 74 issued U.S. patents, 174 issued non-U.S. patents and 216 U.S. and non-U.S. patent applications pending. Similarly, we have 162 registered U.S. and foreign trademarks and 99 U.S. and foreign pending trademark applications. Our U.S. issued patents are scheduled to expire between 2030 and 2045.

We rely on appropriate security and confidentiality measures to safeguard our interests with respect to trade secrets and other proprietary know-how that is not patented (for example, certain manufacturing processes, test equipment designs, algorithms, and procedures, which are not covered by patents or patent applications).

Our R&D employees are subject to confidentiality and proprietary information agreements with us, which include appropriate confidentiality provisions and invention assignment provisions. However, such individuals could breach the terms of such agreements and it could be difficult and costly for us to enforce these agreements. In addition, these agreements may not have been properly entered into on every occasion with the applicable employee.

Seasonality

Project construction activity in North America and Europe tends to be lower in colder months. The installation of a solar tracker requires setting foundations in the ground which is more costly when the ground is frozen. Accordingly, we typically expect to see higher revenues in the second and third quarters when the weather is warmer in the northern hemisphere and lower revenues in the first and fourth quarters when the weather is colder absent other factors. While we expect this seasonality will continue to impact us in the near term as a large portion of our business is in North America and Europe, we expect to see less pronounced seasonal variations as we grow our business in markets in the southern hemisphere.

Historically, our revenue has been impacted by seasonality related to the Federal Investment Tax Credit (“ITC”) step-downs for solar energy projects and seasonal construction activity, but with the passage of the Inflation Reduction Act (“IRA”) in August 2022, the base ITC was raised to 30%, with no step-downs before 2032.

On July 4, 2025, President Trump signed into law the OBBB, which included changes to the energy tax credits. Specifically, the solar ITC now terminates for facilities that are placed in service after December 31, 2027, but that termination does not apply if the taxpayer begins construction on the facility before July 4, 2026. On August 15, 2025, the U.S. Department of Treasury (“Treasury”) and the IRS issued Notice 2025-42 consistent with the executive order, which eliminates the 5% safe harbor for utility-scale solar projects and only allows the physical work test to determine when a project begins construction.

Government Regulation

Environmental Laws and Regulations

We are subject to a variety of environmental, health and safety, and pollution-control laws and regulations in the jurisdictions in which we operate. We do not believe the costs of compliance with these laws and regulations will be material to the business or our operations. We use, handle, generate, store, discharge and dispose of hazardous substances, chemicals and wastes at some of our facilities in connection with our product development, testing and manufacturing activities. Any failure by us to control the use of, to remediate the presence of or to restrict adequately the discharge of such substances, chemicals or wastes could subject us to potentially significant liabilities, clean-up costs, monetary damages and fines or suspensions in our business operations. In addition, some of our facilities are located on properties with a history of use involving hazardous substances, chemicals and wastes and may be contaminated. Although we have not incurred, and do not currently anticipate, any material liabilities in connection with such contamination, we may be required to make expenditures for environmental remediation in the future.

Government Incentives

Government incentives play a significant role in the solar industry and can materially affect market demand, project economics and the overall growth of our business. 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. The range and duration of these incentives varies widely by jurisdiction. Our customers typically use our systems for grid-connected applications, wherein solar power is sold under a power purchase agreement or into an organized electric market. This segment of the solar industry has historically depended on the availability and size of government incentives supporting the use of renewable energy.

The IRA made significant changes to the tax credit regime that applies to solar facilities. As a result of changes made by the IRA, U.S. taxpayers generally are entitled to a 30% ITC for projects placed in service after 2021, increased to 40% if certain “domestic content” requirements are satisfied, subject, in each case, to an 80% reduction to the credit amount if certain prevailing wage and apprenticeship requirements are not satisfied or deemed satisfied (either because the project has a net output of less than 1 MW or because construction begins before January 29, 2023). The IRS issued Notice 2023-38 in May of 2023 setting forth guidance on the domestic content bonus tax credits under the IRA. Uncertainties existed under this guidance, such as how to obtain the direct labor and materials costs to compute the domestic content percentage and how to define manufactured product components associated with trackers. In May of 2024, the IRS issued Notice 2024-41 setting forth further guidance on the domestic content bonus tax credits, including a safe harbor method for calculating domestic content percentages. On January 16, 2025, the IRS released Notice 2025-08, modifying Notice 2023-38 and Notice 2024-41 as well as introducing an updated elective safe harbor method for use in lieu of provisions of the adjusted percentage rule provided in Notice 2023-38 for calculating the domestic content bonus credit amounts applicable for certain qualified facilities and energy projects. Notice 2024-41 and Notice 2025-08 and the updated definitions described therein clarified certain pre-existing uncertainty in the industry, but also introduced new uncertainties. These uncertainties have and could continue to cause our customers to delay projects as they navigate the existing guidance in qualifying for the tax credit and possibly wait for further clarity.

The OBBB increased the domestic content threshold for solar facilities that begin construction after June 16, 2025 to claim the domestic content bonus credit, however, the OBBB did not otherwise amend the requirements for claiming a domestic content bonus credit or the guidance previously issued by the government. As domestic content guidance is not a final rule, it could be further modified by the Trump Administration.

As a result of changes made by the IRA, U.S. taxpayers will generally also be allowed to elect to receive a production tax credit (“PTC”) in lieu of the ITC for qualified solar facilities the construction of which begins before January 1, 2025 and that are placed in service after 2021. The PTC is available for electricity produced and sold to unrelated persons in the ten years following a project’s placement in service and is equal to an inflation-adjusted amount (currently 2.75 cents per kilowatt hour, assuming the prevailing wage requirements described above are satisfied or deemed satisfied, reduced by 80% if those requirements are not satisfied) for every kilowatt-hour of electricity produced by a facility. The available credit amount is increased by 10% if the domestic content requirements described above are satisfied.

In the case of projects which started construction after January 1, 2025, each of the ITC and PTC were replaced by similar “technology neutral” tax credit incentives that mimic the ITC and PTC but also require that projects satisfy a “zero greenhouse gas emissions” standard in order to qualify for the credits (solar is considered an eligible technology and automatically qualifies). Prior to modification under the OBBB, this new credit regime under the IRA applied to projects that began construction prior to the end of 2033 (and possibly later), at which point the credits would have become subject to a phase-out schedule.

While solar power is cost-competitive with conventional forms of generation in many U.S. states even without the ITC, we believe previous step-downs in the ITC in past years have influenced the timing and quantity of some customers’ orders. On July 4, 2025, President Trump signed into law the OBBB, which included changes to the energy tax credits. Specifically, the solar ITC now terminates for facilities that are placed in service after December 31, 2027, but that termination does not apply if the taxpayer begins construction on the facility before July 4, 2026. In addition, the OBBB imposes new foreign entity of concern limitations on the ITC before it expires, which could impact the ability of solar facilities to claim the ITC. Specifically, taxpayers cannot claim the credit in taxable years beginning after enactment of the OBBB if they are prohibited foreign entities (which are generally entities that are formed in or controlled by covered nations, including China, Russia, Iran, and North Korea, as well as entities determined to be under effective control as a result of contracts entered into with such entities). The credit is also disallowed for solar facilities that begin construction after December 31, 2025 that receive material assistance from a prohibited foreign entity. On February 13, 2026, Treasury guidance was released clarifying methods for calculating material assistance from a prohibited foreign entity and requesting comments.

On July 7, 2025, President Trump issued an executive order instructing Treasury to issue updated guidance, including on commencement of construction, within 45 days. On August 15, 2025, Treasury and the IRS issued Notice 2025-42 consistent with the executive order, which eliminates the 5% safe harbor for utility-scale solar projects and only allows the physical work test to determine when a project begins construction. If solar developers are unable to satisfy the physical work test prior to certain deadlines, our business, financial condition, and results of operations could be adversely affected.

The Company expects certain tax provisions of the OBBB, including the reinstatement of 100% bonus depreciation for qualified property and the immediate expensing of U.S.-based R&D activities, to reduce our 2025 taxable income. These accelerated deductions are expected to lower current‑year cash taxes and improve near-term operating cash flows. The favorable impact primarily represents a timing difference. As assets subject to bonus depreciation become fully depreciated and as expensed R&D activities normalize, we expect cash taxes to increase in future periods. The Company continues to evaluate additional guidance expected to be issued by Treasury related to OBBB.

The section 45X advanced manufacturing production tax credit was established as part of the IRA. The section 45X credit is a per-unit tax credit that is earned over time for each clean energy component domestically produced and sold by a manufacturer. The section 45X manufacturing production tax credit applies to eligible components, including torque tube and structural fasteners. Beginning in late 2023 and continuing through 2024 and 2025, we have successfully negotiated, and we continue to successfully negotiate, agreements with key suppliers around sharing the economic benefits of section 45X credits associated with torque tube and structural fasteners. We continue to pursue additional agreements for splitting the economic benefits of section 45X with suppliers for parts we do not manufacture internally. In addition, during the second quarter of 2024, we concluded that certain parts manufactured by the Company qualify for the section 45X advanced production credits.

The OBBB did not modify the phase-out of the section 45X credit or the definitions of eligible components relating to solar trackers; however, the OBBB did impose foreign entity of concern limitations on taxpayers claiming the section 45X credit. Specifically, taxpayers cannot claim the credit in taxable years beginning after enactment of the OBBB if they are prohibited foreign entities (which are generally entities that are formed in or controlled by covered nations, including China, Russia, Iran, and North Korea, as well as entities determined to be under effective control as a result of contracts entered into with such entities). The credit is also disallowed in taxable years beginning after enactment of the OBBB for eligible components that receive material assistance from a prohibited foreign entity. On February 13, 2026, Treasury guidance was released that further

clarified methods for calculating material assistance, and included a request for comments by March 30. We anticipate forthcoming Treasury proposed rule will further clarify the potential impact of the foreign entity of concern limitations may have for credits claimed in 2026 and future years.

Human Capital

We believe our success depends on our ability to attract and retain outstanding employees at all levels of our business. As of December 31, 2025, we had approximately 1,200 full-time employees, of which approximately 66% are located in the U.S., while the other 34% are located throughout the world in Europe, the Middle East, Asia, Latin America, Australia, and Africa. We have not experienced any employment-related work stoppages, and we consider relations with our employees to be good.

We have a team-oriented culture, which we believe helps us to succeed and drive operational excellence. As a rapidly growing business, we rely on the success of our recruitment efforts to attract and retain technically skilled people who can support our ongoing innovation and expansion. We aim to be inclusive in our hiring practices focusing on the best talent for the role, welcoming all genders, nationalities, ethnicities, abilities and other dimensions of diversity. We drive high levels of performance and improvement by prioritizing training and development to ensure our team members are equipped with the knowledge, skills, and tools to succeed.

Item 1A. Risk Factors

In evaluating the Company, you should consider carefully the risks and uncertainties described below, as well as the other information in this Annual Report on Form 10-K, including our consolidated financial statements and related notes appearing at the end of this Annual Report on Form 10-K. The occurrence of any of the following risks could harm our business, financial condition, results of operations and/or growth prospects or

cause our actual results to differ materially from those contained in forward-looking statements we have made in this report and those we may make from time to time. The risks and uncertainties described below are not the only ones facing us. Other events that we do not currently anticipate or that we currently deem immaterial also may adversely affect our business, prospects, financial condition, results of operations, stockholders’ equity, and cash flows.

Risks Related to the APA Acquisition

We may be unable to successfully integrate APA’s business into our business or achieve the anticipated benefits or synergies of the APA Acquisition.

Our ability to achieve the anticipated benefits or synergies of the APA Acquisition will depend in part upon whether we can integrate APA’s business into our existing business in an efficient and effective manner. We may not be able to accomplish this integration process successfully. The successful integration of APA’s business requires an assessment and implementation of several factors, including:

•the ability to successfully combine our respective businesses in a manner that permits us to achieve the cost savings, synergies and other anticipated benefits from the APA Acquisition;

•integrating complex systems, operating procedures, compliance programs, technology, networks and other assets while carrying on our ongoing business in a manner that reduces any adverse impact on customers, suppliers, employees and other constituencies; and

•managing the expanded operations of a larger and more complex company.

In addition, any potential unknown liabilities, liabilities that are significantly larger than we currently anticipate, and unforeseen increased expenses or delays associated with the APA Acquisition, including cash costs of integration, may exceed what we currently anticipate. Any one of these factors could result in increased costs, decreased benefits and diversion of management’s attention, which could materially impact our business, financial condition and results of operations. In addition, even following successful integration, the anticipated benefits or synergies of the APA Acquisition may not be realized fully, or at all, or may take longer to realize than expected.

We will incur significant transaction costs in connection with the integration of APA’s business into our business.

We have incurred and are expected to continue to incur a number of non-recurring costs associated with the integration of APA’s business into our business, combining the operations of APA with ours and achieving desired synergies. These costs have been, and will continue to be, significant. A substantial majority of non-recurring expenses will consist of transaction costs and may include, among others, fees paid to financial, legal, accounting and other advisors and employee retention, severance, and benefit costs. We will also incur costs related to formulating and implementing integration plans. Although we expect that the elimination of duplicative costs, as well as the realization of synergies and efficiencies related to the integration of APA’s business, should allow us to offset these transaction costs over time, this net benefit may not be achieved in the near term or at all.

We and APA will be subject to business uncertainties following the APA Acquisition, which could adversely affect our business.

In connection with the APA Acquisition, it is possible that certain persons with whom we or APA have a business relationship may delay or defer certain business decisions or might decide to seek to terminate,

change or renegotiate their relationships with us or APA, as the case may be, as a result of the APA Acquisition, which could negatively affect our revenues, earnings and cash flows as well as the market price of our common stock. In addition, our and APA’s ability to attract, retain and motivate employees may be impaired for a period of time following the APA Acquisition, as current and prospective employees may experience uncertainty about their roles within the Company following the APA Acquisition.

We may not be able to implement effective internal controls over financial reporting for the APA business in a timely manner or once implemented, such controls may not operate effectively.

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. Prior to our acquisition thereof, APA, as a privately-held company, had not been required to implement or maintain disclosure controls and procedures or internal controls over financial reporting that a public company is required to have, implement and maintain. Under SEC rules, we have one year from the date of the APA Acquisition to implement such disclosure controls and procedures and internal controls over financial reporting at APA. Although we are developing a plan designed to implement effective disclosure controls and procedures and internal controls over financial reporting at APA, we cannot assure you that such plans will be fully implemented in a timely manner or that we will be able to successfully implement and maintain the effectiveness of such plans by the time management assesses the effectiveness of our internal controls, including APA, for fiscal year 2026. In addition, during the continuation of our integration efforts, we may identify deficiencies in APA’s controls. Any failure to timely implement effective internal controls could result in, among other things, a decline in the market price of our stock, restatement of our consolidated financial statements, or reputational harm.

Risks Related to Demand for our Products

If demand for solar energy projects does not continue to grow or grows at a slower rate than we anticipate, our business will suffer.

Our solution is utilized in large-scale ground-mounted solar energy projects. As a result, our future success depends on continued demand for solar energy solutions and the ability of solar equipment vendors to meet this demand. The solar industry is an evolving industry that has experienced substantial changes in recent years, and we cannot be certain that consumers and businesses will adopt solar energy as an alternative energy source at levels sufficient to grow our business. If demand for solar energy fails to develop sufficiently, demand for our products will decrease, which would have an adverse impact on our ability to increase our revenue and grow our business.

The viability and demand for solar energy and the demand for our products are impacted by many factors outside of our control, including but not limited to, the cost and availability of necessary raw materials like steel and of in-demand components like high-voltage breakers, various policies related to the permitting and interconnection costs of solar plants, and the availability of incentives for solar energy and products, which makes it difficult to predict our future prospects.

The viability and demand for solar energy, and in turn, our products, may be affected by many factors outside of our control. While we have been in existence since 1989, we have grown and expanded significantly since then. Our significant growth and expansion, combined with the rapidly evolving and competitive nature of our industry, makes it difficult to predict our future prospects. We have limited insight into emerging trends that may adversely affect our business, financial condition, results of operations and prospects. We have encountered and will continue to encounter risks and difficulties frequently experienced by growing companies in rapidly changing industries, including unpredictable and volatile revenues and increased expenses as we continue to grow our business. Some of the factors outside of our control which may impact the viability and demand for solar energy include:

•availability and scale and scope of government subsidies and incentives to support the development and deployment of solar energy solutions;

•levels of investment by end-users of solar energy products, which tend to decrease when economic growth slows;

•policies and backlog related to the permitting and interconnection costs of solar plants to which we supply our products;

•the emergence, continuance or success of, or increased government support for, other energy generation technologies and products;

•the cost and availability of raw materials necessary to produce solar energy, including steel and polysilicon, and in-demand components like high-voltage breakers;

•regional, national or global macroeconomic trends, which could affect the demand for new energy resources and customers’ ability to finance new projects; and

•shifts in electricity demand, including those associated with the rapid expansion of data centers and other energy-intensive facilities, which may affect the timing, scale or economics of solar development or the competitiveness of solar energy relative to other generation technologies.

If we are not able to mitigate these risks and overcome these difficulties successfully, our business and prospects may be materially adversely affected.

Competitive pressures within our industry may harm our business, results of operations, financial condition and prospects.

The solar tracker industry is globally fragmented and we face intense competition in nearly all of the markets in which we compete. This may result in price competition being greater than expected, which could adversely affect our revenue and margins.

Some of our competitors are developing or are currently manufacturing products based on different solar power technologies that may ultimately have costs similar to or lower than our projected costs. Any failure by us to adopt new or enhanced technologies or processes, or to react to changes in existing technologies, could result in product obsolescence, the loss of competitiveness of our products, decreased revenue and a loss of market share to competitors. In addition, some of our competitors have longer operating histories, lower costs of goods sold, lower operating costs, greater name and brand recognition in specific markets in which we compete or intend to sell our products, greater market shares, access to larger customer bases, greater resources and significantly greater economies of scale than we do. Additionally, new competitors may decide to enter our market as a result of, among other factors, lower barriers to entry and lower R&D costs in comparison with the average costs in R&D in other energy industries. We may also face adverse effects from increased competition in the solar EPC market by EPCs subjecting their subcontractors, such as us, to flow-down contractual clauses which provide that a subcontractor’s obligations to an EPC are identical to the obligations the EPC has to the EPC’s end customer. This may result in higher contractual risk to us, such as “pay if paid” clauses that require EPCs to pay us only when the end customer pays the EPC, higher liquidated damages amounts, increased contractual liabilities above 100% of the contract value and more limited force majeure clauses, among others. As the solar energy market continues to grow, EPCs are also expected to increasingly seek second sources for their suppliers. Any of these factors may materially and adversely affect our business, results of operations, financial condition and prospects.

We face competition from conventional and other renewable energy sources.

We face significant competition from providers of conventional and other renewable energy alternatives such as coal, nuclear, natural gas and wind. We compete with conventional energy sources primarily based on price, predictability of price and energy availability and the ease with which customers can use electricity generated

by solar energy projects. If solar energy systems cannot offer a compelling value to customers based on these factors, then our business growth may be impaired.

Conventional energy sources generally have substantially greater financial, technical, operational, and other resources than solar energy sources, and as a result may be able to devote more resources to the research, development, promotion, and product sales or respond more quickly to evolving industry standards and changes in market conditions than solar energy systems. Conventional and other renewable energy sources may be better suited than solar for certain locations or customer requirements and may also offer other value-added products or services that could help them compete with solar energy sources. In addition, the source of a majority of conventional energy electricity is non-renewable, which may in certain markets allow them to sell electricity more cheaply than electricity generated by solar generation facilities. Non-renewable generation is typically available for dispatch at any time, as it is not dependent on the availability of intermittent resources such as sunlight.

We are dependent on a relatively small number of customers for our sales. A loss of one or more of our significant customers, their inability to perform under their contracts, or their default in payment could harm our business and negatively impact revenue, results of operations, and cash flow.

We are dependent on a relatively small number of customers for our sales, and a small group of customers have historically accounted for a material portion of our revenue. The loss of any one of our significant customers, their inability to perform under their contracts, or their default in payment, could have a materially adverse effect on our revenues and profits. Further, our trade accounts receivable are from companies within the solar industry, and, as such, we are exposed to normal industry credit risks. For the near future, we may continue to derive a significant portion of our net sales from a small number of customers. Accordingly, loss of a significant customer or a significant reduction in pricing or order volume from a significant customer could materially reduce net sales and operating results in any reporting period.

A drop in the price of electricity sold may harm our business, financial condition, results of operations or prospects.

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

•construction of a significant number of new, lower-cost power generation plants, including plants utilizing natural gas, other renewable energy or other generation technologies;

•relief of transmission constraints that enable distant, lower-cost generation to transmit energy less expensively or in greater quantities;

•reductions in the price of natural gas or other fuels;

•utility rate adjustment and customer class cost reallocation;

•decreased electricity demand, including from energy conservation technologies and public initiatives to reduce electricity consumption;

•development of smart-grid technologies that lower the peak energy requirements;

•development of new or lower-cost customer-sited energy storage technologies that have the ability to reduce a customer’s average cost of electricity by shifting load to off-peak times; and

•development of new energy generation technologies that provide less expensive energy.

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

Our results of operations may fluctuate across fiscal periods, which could make our future performance difficult to predict and could cause our results of operations for a particular period to fall below expectations, resulting in a decline in the price of our common stock.

Our quarterly results of operations are difficult to predict and fluctuate significantly. Because we recognize revenue on projects as legal title to equipment is transferred from us to the customer, any delays in large projects from one quarter to another for any reason may cause our results of operations for a particular period to fall below expectations.

We have experienced seasonal and quarterly fluctuations in the past as a result of seasonal fluctuations in our customers’ business. Our end-users’ ability to install solar energy systems is affected by weather, for example, during the winter months in parts of Europe and in the northeastern U.S. Such installation delays can impact the timing of orders for our products. Inclement weather may also affect our logistics and operations by causing delays in the shipping and delivery of our materials, components and products which may, in turn, cause delays in our customers’ solar projects.

In addition, we have had customers experience project delays for reasons as varied as changes in government regulations, supply chain challenges, tax incentives and the interest rate environment. Any unexpected delay in a material project could materially adversely affect our financial performance in a fiscal period. Our financial performance, sales, working capital requirements and cash flow may fluctuate, and our past results of operations may not be good indicators of future performance. Any substantial decrease in revenues would have an adverse effect on our financial condition, results of operations, cash flows and stock price for any given period.

Any increase in interest rates, or a reduction in the availability of tax equity or project debt capital in the global financial markets could make it difficult for end customers to finance the cost of a solar energy system and could reduce the demand for our products.

Many end-users depend on financing to fund the initial capital expenditure required to construct a solar energy project. As a result, any increase in interest rates, or a reduction in the supply of project debt or tax equity financing, could reduce the number of solar projects that receive financing or otherwise make it difficult for our customers or their customers to secure the financing necessary to construct a solar energy project on favorable terms, or at all, and thus lower demand for our products which could limit our growth or reduce our net sales. In addition, we believe that a significant percentage of end-users construct solar energy projects as an investment, funding a significant portion of the initial capital expenditure with financing from third parties. Any increase in interest rates could lower an investor’s return on investment on a solar energy project, increase equity requirements or make alternative investments more attractive relative to solar energy projects, and, in each case, could cause these end-users to seek alternative investments.

Risk Related to the Regulatory Environment

Existing electric utility industry policies and regulations, and any subsequent changes or new related policies and regulations may present technical, regulatory and economic barriers to the purchase and use of solar energy systems that may significantly reduce or delay demand for our products or harm our ability to compete.

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, regional market rules and system permitting, interconnection and operating requirements can deter purchases of renewable energy products, including solar energy systems, by reducing anticipated revenues 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 development in renewable-energy pricing policies in the U.S. occurred when the Federal Energy Regulatory Commission (“FERC”) issued a final rule amending regulations that implement a section of the Public Utility Regulatory Policies Act of 1978 (“PURPA”) on July 16, 2020, which FERC upheld on rehearing on November 19, 2020. The United States Court of Appeals for the Ninth Circuit denied petitions for review of the regulations on November 5, 2023. Among other requirements, PURPA mandates that electric utilities buy the output of certain renewable generators, including qualifying solar energy facilities, below established capacity thresholds. PURPA also requires that such sales occur at a utility’s “avoided cost” rate. FERC’s reforms to its PURPA regulations include modifications: (i) to how regulators and electric utilities may establish avoided cost rates for new contracts; (ii) that reduce from 20 MW to 5 MW the capacity threshold above which a renewable-energy qualifying facility is rebuttably presumed to have non-discriminatory market access, thereby removing the requirement for certain utilities to purchase its output; (iii) that require regulators to establish criteria for determining when an electric utility incurs a legally enforceable obligation to purchase from a PURPA qualifying facility; and (iv) that reduce barriers for third parties to challenge a renewable facility’s PURPA eligibility. These regulations took effect on February 16, 2021, but the net effect of these changes is uncertain, as some changes will not become fully effective until states and other jurisdictions implement the new authorities provided by FERC.

In addition, an ongoing dispute regarding how to calculate the 80MW maximum “power production capacity” for small power qualifying facilities under PURPA was recently resolved. In 2021, FERC certified such a facility based on its net output, rather than total nameplate capability of a facility for purposes of PURPA eligibility. In February 2023, the U.S. Court of Appeals for the D.C. Circuit upheld FERC’s approach to calculating capacity for PURPA eligibility, relying on Chevron deference, whereby courts may defer to an administrative agency’s reasonable statutory interpretation. In June 2024, the U.S. Supreme Court overturned the Chevron deference doctrine and found that courts should instead rely on their own independent statutory interpretations. The Supreme Court later directed the D.C. Circuit to reconsider its ruling on FERC’s approach to calculating capacity for PURPA eligibility. In September 2025, the D.C. Circuit re-affirmed FERC’s approach to certifying a facility based on its net output for purposes of PURPA eligibility. This decision provides regulatory certainty to developers of solar projects.

FERC is also taking steps to encourage the integration of new forms of generation into the electric grid and remove barriers to grid access, which could have positive impacts on the solar energy industry. For example, on July 28, 2023, FERC issued a final rule, designated as Order No. 2023 and modified in part in March 2024, to reform procedures and agreements that electric transmission providers use to interconnect new generating facilities to the existing transmission system. In June 2024, FERC issued a final rule, designated as Order No. 1920, which it modified in part in November 2024 and again in April 2025, to reform the procedures electric transmission providers must use for long-term planning of expansions to the transmission system and the allocation of the resulting costs to transmission customers, including electric generating facilities. Transmission providers’ implementation of Order Nos. 2023 and 1920 is still in process. If these final rules do not have their intended effect or if they are overturned on an appeal, this could negatively impact our business, prospects, and results of operations.

Changes in other current laws or regulations applicable to us or the imposition of new laws, regulations or policies in the U.S., Europe or other jurisdictions in which we do business could have a material adverse effect on our business, financial condition and results of operations. Any changes to government, utility or electric market regulations or policies that favor electric utilities, non-solar generation, or other market participants, or that make construction or operation of new solar generation facilities more expensive or difficult, could reduce

the competitiveness of solar energy systems and cause a significant reduction in demand for our products and services and adversely impact our growth.

The interruption of the flow of components and materials from international vendors could disrupt our supply chain, including as a result of the imposition of additional duties, tariffs and other charges on imports and exports.

We purchase our components through arrangements with various suppliers located across the globe. We depend on our suppliers to source materials and manufacture critical components for our products. Our reliance on these suppliers makes us vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules and costs which could disrupt our ability to procure these components in a timely and cost-efficient manner. The suppliers rely on other suppliers to provide them with raw materials and sub-components that are critical to manufacturing the components of our tracker products. Any shortages of components and materials would affect our ability to timely deliver our products to our customers consistent with our contractual obligations, which may result in liquidated damages or contractual disputes with our customers, harm our reputation and lead to a decrease in demand for our products.

In recent years, our ability to deliver our products in a cost-efficient manner has been, and could continue to be, adversely impacted by other factors not within our control, including, but not limited to, 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, increases in the cost of fuel, sanctions and labor availability and cost.

Further, our products are manufactured from steel and, as a result, our business is significantly affected by the price of steel. At times, pricing and availability of steel can be volatile due to numerous factors beyond our control, including general domestic and international economic conditions, global capacity, import levels, fluctuations in the costs of raw materials necessary to produce steel, sales levels, competition, consolidation of steel producers, labor costs, import duties and tariffs and foreign currency exchange rates. When steel prices are higher, the prices that we charge customers for our products may increase, which may decrease demand for our products. If we do not increase our prices due to an increase in the price of steel, we will experience lower profitability on our products. Conversely, if steel prices decline, customers may demand lower prices and our and our competitors’ responses to those demands could result in lower sale prices, lower volume, and consequently, negatively affect our profitability.

In addition, as noted above, the IRA provides incremental tax credits for U.S. solar projects satisfying domestic content requirements. If we are unable to provide our tracker products in a manner that satisfies applicable domestic content requirements and our competitors are able to do so, we might experience a decline in sales for U.S. projects. In addition, compliance with these requirements may increase our production costs. In light of the foregoing, our U.S. sales, profitability and results of operations in the U.S. may be adversely affected by the applicable domestic content requirements which must be satisfied in order for solar projects to be eligible for these incremental credits.

Other events that could also cause disruptions to our supply chain include:

•the imposition of additional trade law provisions or regulations;

•the imposition of additional duties, tariffs and other charges or quotas on imports and exports, or other trade law provisions or regulations, such as anti-dumping and countervailing duties, and our ability to pass along such charges to our customers;

•continued or renewed instability in the global supply of semiconductors, which has and could continue to impact the timely receipt of our self-powered controller;

•foreign currency fluctuations;

•inflationary pressure and its impact on labor, commodities and fuel prices;

•natural disasters, severe weather, political instability, war, such as the Russia-Ukraine war or conflict in the Middle East, terrorist attacks, social unrest and economic instability in the regions in which our suppliers are located, or through which our components and materials travel;

•shipping and transport disruptions;

•public health issues, such as a pandemic or other epidemic, and their effects (including measures taken by governmental authorities in response to their effects);

•theft or other loss;

•restrictions on the transfer of funds;

•the financial instability or bankruptcy of vendors; and

•significant labor disputes, strikes, work stoppages or boycotts.

Any significant disruption to our ability to procure our products, and our suppliers’ ability to procure materials to manufacture our products and components for our products could increase the cost or reduce or delay the supply of components and materials available to us and adversely affect our business, financial condition, results of operations and profitability. Further, if any of our suppliers were unable or unwilling to manufacture the components that we require for our products in sufficient volumes and at high quality levels or renew existing terms under supply agreements, we would need to identify, qualify and select acceptable alternative suppliers. An alternative supplier 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. Any significant interruption in manufacturing by our suppliers would require us to reduce our supply of products to our customers or increase our shipping costs to make up for such delays, which in turn could reduce our revenues and margins, harm our relationships with our customers, damage our reputation with other stakeholders involved with solar projects and cause us to forego potential revenue opportunities.

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

Escalating trade tensions, including between the U.S. and China, have led to increased tariffs and trade restrictions, including tariffs applicable to certain materials and components for our products or for products used in solar energy projects more broadly, such as module supply and availability. More specifically, in March 2018, the U.S. 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 extended these tariffs to cover imports of derivative steel and aluminum articles on February 2020 under the same legal authority. These tariffs were increased on February 10, 2025, pursuant to two proclamations from President Trump (the “February 2025 Proclamations”), resulting in across-the-board 25% duties on steel and aluminum imports. Additionally, all previous alternative arrangements, such as complete exemptions, hard quotas, or tariff rate quotas, with trading partners on imports of steel and aluminum products, have been eliminated. The February 2025 Proclamations also eliminated the system for exclusions, under which thousands of products were allowed to enter the U.S. free of these additional duties and created a process by which additional “derivative” products could be added to the scope of the tariffs by request of the domestic producer. To the extent we 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. In addition, the threat of potential tariffs can create uncertainty among our customers and slow the rate of existing projects and projects in our orderbook.

of Canadian energy resources, which are subject to a 10% ad valorem rate of duty) and an additional 10% ad valorem rate of duty on all imports from China. On March 4, 2025, the previously announced 25% tariff on Canadian and Mexican goods took effect and the tariff on Chinese goods was doubled to 20%. On June 4, 2025 tariffs on steel and aluminum increased from 25% to 50% on all steel and aluminum coming from Canada. Further, on July 31, 2025, President Trump issued an executive order increasing the ad valorem rate on imports from Canada to 35%. President Trump also has threatened a 30% ad valorem rate on imports from Mexico, though those are not currently in effect.

On April 2, 2025, President Trump introduced a baseline tariff rate of 10% on most countries and individualized rates on some countries of up to 50% (the “reciprocal tariffs”). On April 9, 2025, President Trump increased tariffs for Chinese goods to 125% (making the tariff rate for certain products up to 145% due to the “stacking” nature of the relevant tariffs), while also issuing an executive order that the reciprocal tariffs that had been announced on April 2, 2025 for other countries would be reduced to a baseline rate of 10% for a period of 90 days starting on April 10, 2025. On July 7, 2025, President Trump extended the initial 90-day pause on the reciprocal tariffs (except for those relating to China) and maintained the 10% baseline rate until August 1, 2025. On July 31, 2025, President Trump announced via an executive order reciprocal tariffs above the 10% baseline rate for a number of countries; these rates became effective as of August 7, 2025. In November 2025, the Supreme Court heard arguments in a case challenging tariffs imposed under the International Emergency Economic Powers Act (“IEEPA”). In February 2026, the Supreme Court issued a ruling that IEEPA does not authorize the imposition of tariffs. Although the ruling has been issued, its implications for trade policy and related administrative actions remain uncertain. The Company is reviewing the decision and will evaluate its potential impact, including with respect to any potential refunds, as further information becomes available.

President Trump also launched a new Section 301 investigation into Brazil’s alleged unreasonable or discriminatory trade practices; initiated a new Section 232 investigation into imports of polysilicon and its derivatives and a new Section 232 investigation into imports of unmanned aircraft systems and their parts and components, among other Section 232 investigations; and announced a 50% tariff on imports of copper following the conclusion of a Section 232 investigation, effective August 1, 2025.

We are continuing to evaluate the potential impact of the imposition of the announced tariffs, the effect of the Supreme Court decision on tariffs described above, and any additional or retaliatory tariffs, to our business and financial condition. While we do not believe that the tariffs announced by the U.S. in 2025 and through the date of filing this Form 10-K in 2026 will have a material adverse effect upon our results of operations, financial condition, or liquidity, the actual impact of new tariffs is subject to a number of factors including the effective date and duration of such tariffs, changes in the amount, scope and nature of the tariffs in the future, any countermeasures that the target countries may take and any mitigating actions that may become available.

More broadly, President Trump has directed the U.S. Department of Commerce (the “USDOC”), the U.S. Trade Representative (the “USTR”), and other agencies, to review and identify unfair trade practices by other countries and recommend appropriate actions, as well as recommend modifications of antidumping and countervailing duty (“AD/CVD”) laws to further induce compliance by foreign respondents and governments involved in those proceedings. These directives issued under the America First Trade Policy and the Reciprocal Trade and Tariffs Presidential Memoranda may have far-reaching effects on the global trading system.

In January 2018, the U.S. adopted a tariff on imported solar modules and cells pursuant to Section 201 of the Trade Act of 1974. The tariff was initially set at 30%, with a gradual reduction over four years to 15%. While this tariff does not apply directly to the components we import, it may indirectly affect Array by impacting the financial viability of solar energy projects, which could in turn reduce demand for our products. On February 4, 2022, former President Biden extended the safeguard tariff for an additional four years, starting at a rate of 14.75% and reducing that rate each year to 14% in 2026, and directed the USTR to conclude agreements with Canada and Mexico on trade in solar products. On July 7, 2022, the U.S. and Canada entered into a non-

binding memorandum of understanding in which the U.S. agreed to suspend application of the safeguard tariff to Canadian crystalline silicon PV cells imported as of February 1, 2022. While this tariff does not apply directly to the components we import, it may indirectly affect us by impacting the financial viability of solar energy projects, which could in turn reduce demand for our products.

Furthermore, starting in July 2018, the U.S. adopted four lists of tariffs (Lists 1,2,3, and 4A) on $550 billion worth of Chinese imports, including, inverters and power optimizers. Products on Lists 1, 2, and 3 are subject to 25% tariffs, while products on List 4A are subject to 7.5% tariffs. On December 16, 2024, the USTR announced that it would increase Section 301 tariffs on polysilicon and wafers to 50% in 2025. At the same time, the USTR implemented 14 tariff exclusions for listed solar cell and wafer manufacturing equipment. While these tariffs are not directly applicable to our products, they could impact the solar energy projects in which our products are used, which could lead to decreased demand for our products.

On August 18, 2023, the USDOC issued final affirmative determinations of circumvention with respect to certain crystalline solar photovoltaic (“CSPV”) cells and modules produced in Cambodia, Malaysia, Thailand and Vietnam using parts and components from China. As a result, certain CSPV cells and modules from Cambodia, Malaysia, Thailand and Vietnam are now subject to AD/CVD orders on CSPV cells and modules from China that have been in place since 2012. Subject to certain certification and utilization conditions, imports of CSPV cells and modules covered by the circumvention determinations that entered the U.S. during the two-year period prior to June 6, 2024 which had been authorized by the former President Biden on June 2022 were not subject to AD/CVD cash deposit or duty requirements. Imports of CSPV cells and modules from the four Southeast Asian countries covered by the circumvention determination that entered the U.S. on or after June 6, 2024 are subject to AD/CVD cash deposit requirements of the China AD/CVD orders and, possibly, final AD/CVD duty liability. Cash deposit rates for CSPV modules covered by the China AD/CVD orders vary significantly depending on the producer and exporter of the modules and may amount to over 250% of the entered value of the imported merchandise.

Additionally, in October 2023, a coalition of U.S. aluminum extruders and a labor union filed AD/CVD cases on aluminum extrusions from fifteen countries. The USDOC has initiated investigations based on the petitions. Certain components in our trackers, including certain clamps, U-joints, and bearing housings are made using extruded aluminum. In September 2024, the USDOC released its final determination from their investigations against aluminum extrusions from multiple countries. On October 30, 2024, the U.S. International Trade Commission (“USITC”) voted to find no injury in its pending AD/CVD investigation, meaning that the USDOC’s AD/CVD orders will not go into effect. The coalition of petitioners may still appeal the USITC’s decision, and we will continue to monitor developments in the appeal process. If the USITC’s decision is overturned on appeal, the imposition of AD/CVD orders could negatively impact our business, financial condition, and results of operations.

On April 24, 2024, the American Alliance for Solar Manufacturing Trade Committee, an ad hoc coalition of domestic producers of CSPV cells and modules, filed a petition with the USDOC and the USITC seeking the imposition of AD/CVD tariffs on imports of CSPV cells and modules from Cambodia, Malaysia, Thailand and Vietnam. On May 20, 2025, the USITC made a final determination that U.S. industry had been materially injured by imports of CSPV cells, whether or not assembled into modules, from Malaysia and Vietnam and threatened with material injury by such imports from Cambodia and Thailand. On June 24, 2025, the USDOC issued AD/CVD orders that took effect on June 24, 2025. The rates under the AD/CVD orders vary from below 1% to more than 3,400%, depending on the relevant company.

On July 17, 2025, the Alliance for American Solar Manufacturing and Trade, a coalition of U.S.-based solar manufacturers, filed a petition with the USDOC and USITC seeking the imposition of AD/CVD tariffs on imports of CSPV cells and modules from India, Indonesia, and Laos. The petition alleges dumping margins of 213.96% for India, 89.65% for Indonesia, and 245.79% to 249.09% for Laos. The final determinations by the USDOC are expected sometime in the summer of 2026.

While we do not sell solar modules, the degree of our exposure is dependent on, among other things, the impact of the AD/CVD orders on the projects that are also intended to use our products, with such impact being largely out of our control. We have seen a number of projects in our order book delayed as a result of the USDOC investigations, and effective enforcement of the AD/CVD orders could negatively impact our results of operations.

Tariffs and the possibility of additional tariffs in the future like those described above have created uncertainty in the industry. If the price of solar systems in the U.S. increases, the use of solar systems could become less economically feasible and could reduce our gross margins or reduce the demand of solar systems manufactured and sold, which in turn may decrease demand for our products. Additionally, existing or future tariffs may negatively affect key customers, suppliers, and manufacturing partners. Such outcomes could adversely affect the amount or timing of our revenues, 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. It is difficult to predict what further trade-related actions governments may take, which may include additional or increased tariffs and trade restrictions, and we may be unable to quickly and effectively react to such actions.

We may not be able to convert our orders in backlog into revenue.

Backlog can be subject to large variations from quarter to quarter and comparisons of backlog from period to period are not necessarily indicative of future revenue. The contracts comprising our backlog may not result in actual revenue in any particular period or at all, and the actual revenue from such contracts may differ from our backlog estimates. The timing of receipt of revenue, if any, on projects included in backlog could change because many factors affect the scheduling of projects. Cancellation of or adjustments to contracts may occur. The failure to realize all amounts in our backlog could adversely affect our future revenue and gross margins. As a result, our backlog as of any particular date may not be an accurate indicator of our future financial performance.

Actions addressing determinations of forced labor practices in China and legislation and policies adopted to address such practices may disrupt the global supply of solar panels and have an adverse material effect on our business, financial condition and results of operations.

Solar panel imports to the U.S. have also been, and may continue to be, impacted by the Uyghur Forced Labor Prevention Act (“UFLPA”) that was signed into law by former President Biden on December 23, 2021. According to U.S. Customs and Border Protection (“CBP”), “[the UFLPA] establishes a rebuttable presumption that the importation of any goods, wares, articles, and merchandise mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region of the People’s Republic of China, or produced by certain entities, is prohibited by Section 307 of the Tariff Act of 1930 and that such goods, wares, articles, and merchandise are not entitled to entry to the United States.” U.S. Customs and Border Protection stated that “[t]he presumption applies unless the Commissioner of CBP determines there is an exception through clear and convincing evidence, that the goods, wares, articles, or merchandise were not produced using forced labor or that UFLPA does not apply.” There continues to be uncertainty in the market around achieving full compliance with the UFLPA, whether related to sufficient traceability of materials or other factors. This has created a significant compliance burden and constrained solar panel imports. We cannot currently predict what, if any, impact the UFLPA will have on the overall future supply of solar panels into the U.S. and the related timing and cost of our clients’ solar project, development and construction activities. While we do not import or sell solar panels, project delays caused by solar panel constraints may negatively impact our product delivery schedules and future sales, and therefore our business, financial condition, and results of operations.

Since 2016, U.S. Customs and Border Protection has issued a number of withhold release orders (“WROs”) directed at forced labor in China, including WROs directed specifically at activity in the Xinjiang Uyghur Autonomous Region. As a result of these orders, certain products, including solar panels manufactured with polysilicon from Xinjiang, are effectively barred from entering the U.S. We cannot determine with certainty

whether our suppliers may become subject to a WRO, which could subject us to legal, reputational, and other risks. If this were to occur, we might have to find alternative suppliers on short notice, resulting in construction delays and disruption and higher costs. Additionally, WROs have and could continue to impact the importation of solar panels. While we are not directly involved in the importation of solar panels, such WROs can negatively impact the global solar market and the timing and viability of solar projects to which we sell our products, which could have a material adverse effect on our business, financial condition and results of operations.

The reduction, elimination, expiration, or our failure to optimize the benefits of government incentives for, or regulations mandating the use of, renewable energy and solar energy, particularly in relation to our competitors, could reduce demand for solar energy systems and harm our business.

Our customers typically use our systems for grid-connected applications wherein solar power is sold 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 supporting the use of renewable energy. Consequently, the reduction, elimination or expiration of government incentives for grid-connected solar electricity 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 renewable energy adoption rates increase or as a result of legal challenges, the adoption of new statutes or regulations or changes to existing regulations, or the passage of time. These reductions, eliminations or expirations could occur without warning. There is no guarantee that such policies and incentives will continue to exist in the current form, if at all. The reduction, elimination or expiration of such incentives could reduce customer demand for our offerings, lead to a loss of customers and potential customer projects, and could harm our business, operating results and cash flows.

While government incentives are intended to encourage investments in new solar projects, the impact the tax credit regime applicable to solar facilities in the U.S. will have on our results of operations is unclear. As discussed in the section in Item 1 . Business captioned “Government Regulation—Government Incentives,” the OBBB included changes to the energy tax credits, specifically that the solar ITC now terminates for facilities that are placed in service after December 31, 2027, but that termination does not apply if the taxpayer begins construction on the facility before July 4, 2026. This could act as an incentive for taxpayers to construct facilities before a certain date. On August 15, 2025, Treasury and the IRS issued Notice 2025-42, which eliminates the 5% safe harbor for utility-scale solar projects and only allows the physical work test to determine when a project begins construction. Changes or reductions to these and other government incentives could have a material adverse impact on our business, financial condition and results of operations.

In addition, if we are unable to meet the foreign entity of concern or domestic content requirements necessary for customers using our tracker products to qualify for the base tax credit or the incremental domestic content bonus credit and our competitors are able to do so, we might experience a decline in sales for U.S. projects. On February 13, 2026, Treasury guidance was released clarifying methods for calculating material assistance from a prohibited foreign entity and requesting comments. The timing and nature of further of implementing regulations clarifying the foreign entity of concern requirements as applied to our products remain uncertain. In addition, the Trump Administration could modify the guidance implementing the domestic content bonus credit. Depending on the criteria set forth in those regulations or other guidance, we may not have an adequate supply of tracker products satisfying the requirements, which could put us at a competitive disadvantage relative to suppliers who are able to maintain a more robust domestic supply chain. In addition, compliance with this requirement may increase our production costs. As a result of these risks, the foreign entity of concern and domestic content requirements may have a material adverse impact on our U.S. sales, business and results of operations.

Moreover, changes in policies of recent U.S. presidential administrations have created regulatory uncertainty in the renewable energy industry, including the solar energy industry, and have adversely affected and may continue to adversely affect our business. For example, since 2015, the U.S. joined, withdrew from, rejoined and then withdrew again from the 2015 Paris Agreement on climate change mitigation following changes in administration among U.S. Presidents Obama, Trump, Biden and Trump, respectively. The international markets in which we operate or may operate in the future may have or may put in place policies to promote renewable energy, including solar. These incentives and mechanisms vary from country to country. In seeking to achieve growth internationally, we may make investments that, to some extent, rely on governmental incentives and support in a new market. We may not be able to optimize the benefits offered by these incentives or realize the growth that we expect from investments in the incentives, particularly in relation to competitors whose products might benefit disproportionately from these incentives. In addition, there is uncertainty regarding how the Trump Administration will implement the OBBB through regulations.

There is no assurance that governments will continue to provide sufficient incentives and support to the solar industry and that the industry in any particular country will not suffer significant downturns in the future as the result of changes in public policies or government interest in renewable energy, any of which could adversely affect demand for our solar products.

We may incur obligations, liabilities or costs under environmental, health and safety laws, which could have an adverse impact on our business, financial condition and results of operations.

Our operations involve the use, handling, generation, storage, discharge and disposal of hazardous substances, chemicals and wastes. As a result, we are required to comply with national, state, local, and foreign laws and regulations regarding the protection of the environment and health and safety. Adoption of more stringent laws and regulations in the future could require us to incur substantial costs to come into compliance with these laws and regulations. In addition, violations of, or liabilities under, these laws and regulations may result in restrictions being imposed on our operating activities or in our being subject to adverse publicity, substantial fines, penalties, criminal proceedings, third-party property damage or personal injury claims, cleanup costs, or other costs.

Risks Related to Intellectual Property

If we fail to, or incur significant costs in order to, obtain, maintain, protect, defend or enforce our intellectual property and other proprietary rights, our business and results of operations could be materially harmed.

Our success depends to a significant degree on our ability to protect our intellectual property and other proprietary rights. We rely on a combination of patent, trademark, copyright, trade secret and unfair competition laws, as well as confidentiality and license agreements and other contractual provisions, to establish and protect our intellectual property and other proprietary rights. Such means may afford only limited protection of our intellectual property and may not: (i) prevent our competitors 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.

We have applied for patents in numerous countries across the world, including in the U.S., Europe, and China, some of which have been issued. We cannot guarantee that any of our pending patent applications or other applications for intellectual property registrations will be issued or granted or that our existing and future intellectual property rights will be sufficiently broad to protect our proprietary technology. While a presumption of validity exists with respect to U.S. patents issued to us, there can be no assurance that any of our patents, patent applications, or other intellectual property rights will not be, in whole or in part, opposed, contested, challenged, invalidated, circumvented, designed around, or rendered unenforceable. If we fail to obtain issuance of patents or registration of other intellectual property, or our patent claims or other intellectual property rights are rendered invalid or unenforceable, or narrowed in scope, the coverage of patents and other

intellectual property rights afforded our products could be impaired. Even if we are to obtain issuance of further patents or registration of other intellectual property, such intellectual property could be subjected to attacks on ownership, validity, enforceability, or other legal attacks. Any such impairment or other failure to obtain sufficient intellectual property protection could impede our ability to market our products, 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.

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 U.S., we may be at greater risk that our proprietary rights will be circumvented, misappropriated, infringed, or otherwise violated. Filing, prosecuting, maintaining, and defending our intellectual property in all countries throughout the world may be prohibitively expensive, and we may choose to forego such activities in some applicable jurisdictions. The lack of adequate legal protections of intellectual property or failure of legal remedies or related actions in jurisdictions outside of the U.S. could have a material adverse effect on our business, financial condition, results of operations, and prospects.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

We rely heavily on nondisclosure agreements and technical and organizational measures to protect the unpatented know-how, trade secrets, technology, and other proprietary information on which we rely to maintain our competitive position. However, we cannot guarantee that we have entered into such agreements with each party that has or may have had access to our proprietary information, know-how, technology or trade secrets, including third-party manufacturers, other suppliers, customers, other stakeholders involved in solar projects, or other business partners or prospective partners. Moreover, no assurance can be given that these agreements will be effective in controlling access to, distribution, use, misuse, misappropriation or disclosure of our proprietary information, know-how and trade secrets. Technical and organizational measures can also be vulnerable to attacks by third parties. Such measures may also not be sufficient to completely safeguard our know-how, trade secrets, technology or other proprietary information.

We may need to defend ourselves against third-party claims that we are infringing, misappropriating or otherwise violating others’ intellectual property rights, which could divert management’s attention, cause us to incur significant costs, and prevent us from selling or using the technology to which such rights relate.

Our competitors and other third parties hold numerous patents related to technology 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 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. 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, and we cannot be certain that we would be successful in defending against any such claims in litigation or other proceedings. 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, and from making, selling or incorporating certain components or intellectual property into the products and services we offer. As a result, we could be forced to redesign our products and services, and/or to establish and maintain alternative branding for our products and services. To avoid litigation or being prohibited from marketing or selling the relevant products or services, we could seek a license from the applicable third party, which could require us to pay significant royalties, licensing fees, or other payments,

increasing our operating expenses. If a license is not available on reasonable terms, or at all, we may be required to develop or license a non-violating alternative, either of which could be infeasible or require significant effort and expense. If we cannot license or develop a non-violating alternative, we would be forced to limit or stop sales of our offerings and may be unable to effectively compete. Finally, any litigation or claims, whether or not valid, could result in substantial costs, negative publicity and diversion of resources and management attention, any of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

We may be subject to claims that our employees, consultants, or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property.

Many of our employees and consultants are currently or were previously employed at other companies in our field, including our competitors or potential competitors. Although we try to ensure that our employees and consultants do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these individuals have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Litigation may be necessary to defend against these claims. If we fail to successfully defend any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Even if we are successful in defending against such claims, litigation would result in substantial costs and be a distraction to management.

In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Our Operations

We depend upon a number of outside vendors. Our operations could be disrupted if we encounter problems with these vendors.

We depend upon a number of vendors to manufacture certain components used in our products. Our reliance on these vendors makes us vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields and costs.

If any of our vendors were unable or unwilling to manufacture the components that we require for our products in sufficient volumes and at high quality levels or renew existing terms under supply agreements, we would have to identify, qualify and select acceptable alternative vendors, if not already multi-sourced. Manufacturing the components manufactured by our vendors at our principal manufacturing facility may lower our cost efficiency, and an alternative vendor 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. Any significant interruption in manufacturing would require us to reduce our supply of products to our customers or increase our shipping costs to make up for delays in manufacturing, which in turn could reduce our revenues, harm our relationships with our customers and damage our reputation with local installers and potential end-users and cause us to forego potential revenue opportunities.

Delays in construction projects and any failure to manage our inventory could have a material adverse effect on us.

Many of our products are used in large‐scale projects, which generally require a significant amount of planning and preparation and which can be delayed and rescheduled for a number of reasons, including customer or partner labor availability, difficulties in complying with environmental and other government regulations or obtaining permits, interconnection delays, financing issues, changes in project priorities, additional time required to acquire rights‐of‐way or property rights, unanticipated soil conditions, or health‐related shutdowns

or other work stoppages. These delays may result in unplanned downtime, increased costs and inefficiencies in our operations, and increased levels of excess inventory.

Significant changes in the cost of raw materials could adversely affect our financial performance.

We are subject to risk from fluctuating market prices of certain commodity raw materials, including steel and aluminum, that are used in our products. Prices of these raw materials may be affected by supply restrictions or other market factors from time to time, and we do not enter into hedging arrangements to mitigate commodity risk. Significant price changes for these raw materials could reduce our operating margins if we are unable to recover such increases from our customers, and could harm our business, financial condition and results of operations.

We are dependent on transportation and logistics providers to deliver our materials and products in a cost-efficient manner. Disruptions to transportation and logistics, including increases in shipping costs, could adversely impact our financial condition and results of operations.

We rely on transportation and logistics providers for the delivery of the raw materials and components used to manufacture our products, and to deliver our completed products to our customers. We may also incur additional shipping costs when we need to accelerate delivery times. The delivery of necessary materials for production, as well as our ability to deliver our products to our customers in a fast and cost-efficient manner 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, disruptions to shipping facilities as a result of a pandemic or other epidemics, and other factors not within our control. Disruptions to transportation and logistics, including increases in shipping costs, could adversely impact our financial condition and results of operations.

For example, in the recent past we have seen disruptions of container shipping traffic through the Red Sea create port congestion, especially in Asia, and cause many shipping companies to pause shipments through the Suez Canal and the Red Sea as a result of attacks against commercial vessels in the area, affecting transit times, capacity, and shipping costs for routes connecting the rest of the world with Asia. To address the persisting challenges arising from prolonged transit times, we have increased our local sourcing efforts where feasible within certain regions. These measures aim to reduce delays to get the product to project sites on time. There is still uncertainty on how long disruptions and the severity of their impact on our operations may last, but we continue to monitor such situations and evaluate our procurement and supply chain strategies, to reduce any negative impact on our business, financial condition, and results of operations.

Defects or performance problems in our products could result in loss of customers, reputational damage and decreased revenue, and we may experience delays, disruptions or quality control problems in our manufacturing operations.

Our products may contain undetected 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 or manufacturing difficulties, 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 the replacement or recall of our products, temporary suspension or delay in our production line until the errors or defects can be investigated and addressed, shipment delays, rejection of our products, damage to our reputation, lost revenue, diversion of our engineering personnel from our product development 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.

Defective components may give rise to warranty, indemnity or product liability claims against us that exceed any revenue or profit we receive from the affected products. Our limited warranties cover defects in materials and workmanship of our products under normal use and service conditions. As a result, we bear the risk of warranty claims long after we have sold products and recognized revenue. While we have accrued reserves for

warranty claims, our estimated warranty costs for previously sold products may change to the extent the warranty claims profile of future products is not comparable with that of earlier generation products under warranty. Our warranty accruals 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 actual performance of our systems, causing us to incur substantial unanticipated expense to repair or replace defective products in the future or to compensate customers for defective products. Our failure to accurately predict future claims could result in unexpected volatility in, and have a material adverse effect on, our financial condition, all of which could have a material effect on our business financial condition and results of operations.

Failure by our vendors or our component or raw material suppliers to use ethical business practices and comply with applicable laws and regulations may adversely affect our business.

We do not control our vendors or suppliers or their business practices. Accordingly, we cannot guarantee that they follow ethical business practices such as fair wage practices and compliance with environmental, safety and other local laws. A lack of demonstrated compliance could lead us to seek alternative manufacturers or suppliers, 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 manufacturers or suppliers or the divergence of a supplier’s labor or other practices from those generally accepted as ethical in the U.S. or other markets in which we do business could also attract negative publicity for us and harm our business.

If we fail to retain our key personnel or if we fail to attract additional qualified personnel, we may not be able to maintain key relationships with customers and suppliers or achieve our anticipated level of growth, which could cause our business to suffer

Our future success and ability to implement our business strategy depends, 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, and we face challenges identifying, hiring and retaining qualified personnel in many areas of our business. Integrating new employees into our team could prove 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. 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.

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 and strong customer service. We believe that maintaining the quality of our workforce is critical to our existing customer relationships and our ability to win new customers. As a result, the loss of key personnel and the relationships they have built with our customers and suppliers could reduce demand for our products, undermine the loyalty of our customers or reduce our ability to attract new customers and adversely impact our ability to increase our market share and revenue.

Our continued planned expansion into new markets could subject us to additional business, financial, regulatory and competitive risks.

Part of our strategy is to continue to grow our revenues from international markets, including entering new geographic markets to expand our current international presence, entering into joint-venture or licensing arrangements with companies in certain markets, expanding our relationships with value-added resellers of our

products in some countries, and utilizing locally sourced components in our products in jurisdictions where locally sourced components are a regulatory or customer requirement.

Our strategy continues to be to grow revenues outside of the U.S., including broader North America, as well as Latin America, Europe, the Middle East, Asia, and Australia. The products and services we intend to offer in these regions may differ from our current products and services in several ways, such as the consumption and utilization of local raw materials, components and logistics, the re-engineering of select components to reduce costs, and region-specific customer training, site commissioning, warranty remediation and other technical services.

These markets have different characteristics from the markets in which we currently sell products, and our success will depend on our ability to adapt properly to these differences. These differences include differing regulatory requirements, including tax laws, trade laws, labor regulations, tariffs, export quotas, customs duties or other trade restrictions, limited or unfavorable intellectual property protection, local content requirements, international political or economic conditions, restrictions on the repatriation of earnings, longer sales cycles, warranty expectations, product return policies and cost, and performance and compatibility requirements. In addition, expanding into new geographic markets will increase our exposure to presently existing risks, such as fluctuations in the value of foreign currencies and difficulties and increased expenses in complying with U.S. and foreign laws, regulations and trade standards, including the U.S. Foreign Corrupt Practices Act.

Failure to develop these new products successfully or to otherwise manage the risks and challenges associated with our potential expansion into new geographic markets could adversely affect our revenues and our ability to achieve or sustain profitability.

We have been and will in the future continue to be exposed to risks from currency exchange rate fluctuations between the U.S. dollar and foreign currencies that could adversely affect our financial results and comparability of our results between financial periods.

Changes in exchange rates may affect our financial condition and results of operations. Appreciation of the U.S. dollar against the euro, the Brazilian real or other currencies in which our net sales are denominated may generally have the effect of decreasing our net sales figures. Movements in the exchange rate of the U.S. dollar to the euro, the Brazilian real or other currencies, could increase the amount of cash that must be generated in foreign currencies in order to pay the principal and interest on our 1.00% Convertible Senior Notes due 2028 (the “2028 Convertible Notes”) and our 2.875% Convertible Senior Notes due 2031 (the “2031 Convertible Notes” and, together with the 2028 Convertible Notes, the “Convertible Notes”) and our other U.S. dollar denominated indebtedness. We are unable to predict with any precision future movements of the exchange rate of the U.S. dollar against foreign currencies or their effect on our business or results of operations.

Inadequacy of our insurance coverage could have a material and adverse effect on our business, financial condition and results of operations.

We maintain third party insurance coverage against various liability risks and risks of loss, including general liability, auto liability, property, cargo, errors and omissions, data security breach, crime and directors’ and officers’ liability. Potential liabilities or other loss associated with these risks or other events could exceed the coverage provided by such arrangements resulting in significant uninsured liabilities or other loss, which could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to Information Technology

Failure to effectively utilize information technology systems or implement new technologies could disrupt our business or reduce our sales or profitability.

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 we rely upon are also subject to damage or interruption from a number of causes, including power outages; computer and telecommunications failures; ransomware, computer viruses, malware, phishing or distributed denial-of-service attacks; security breaches; cyber-attacks; catastrophic events such as fires, floods, earthquakes, tornadoes, or hurricanes; acts of war or terrorism and design or usage errors by our employees or contractors.

Compromises, interruptions or shutdowns of our systems, including those managed by third parties, whether intentional or inadvertent, could lead to delays in our business operations and, if significant or extreme, affect our results of operations, potentially materially.

The failure of our information technology systems and the third-party systems we rely on to perform as designed, or our failure to implement and operate them effectively, could disrupt our business or subject us to liability and thereby have a material adverse effect on our business, financial condition, results of operations and prospects.

Cybersecurity or other data incidents, including unauthorized disclosure of personal or sensitive data or theft of confidential information could harm our business.

Our commercial success depends on developing, implementing, and maintaining robust cybersecurity measures to safeguard our information technology systems and protect the confidentiality, integrity and availability of our data. Our or our third-party business partners’ information technology systems are vulnerable to cybersecurity incidents and attacks, including malicious intrusion, malware or ransomware attacks, denial-of-service attacks, and other system disruptions caused by unauthorized third parties. Cybersecurity incidents can also include employee or personnel failures, fraud, phishing or other social engineering attempts or other methods to cause confidential information, payments, account access or access credentials, or other data to be transmitted to an unintended recipient. Attempts by threat actors or other unauthorized third parties to penetrate or otherwise gain access to our information technology systems, or the systems of our third-party business partners through fraud or other means of deceit, have in the past, and may in the future, if successful, result in the misappropriation of personal information, data, financial information or confidential business information. Hardware, software or applications we utilize may contain defects in design or manufacture or other problems that could unexpectedly compromise information security. In addition, our employees, contractors or our third-party business partners may attempt to circumvent our security measures in order to misappropriate such information and data and may purposefully or inadvertently cause a breach or other compromise involving such information and data. We increasingly rely on commercially available systems, software, cloud-based services, tools (including encryption technology) and monitoring to provide security and oversight for processing, transmission, storage and protection of confidential information and personal data, and we are not able to ensure that each of these systems is free from malicious code. The sophistication of threats continues to evolve and grow, including the risk associated with the use of emerging technologies, such as artificial intelligence and quantum computing. Despite advances in security hardware, software, and encryption technologies, and our own information security program and safeguards, there is no guarantee that our defenses and program will be adequate to safeguard against all data security breaches, cybersecurity attacks, misappropriation of confidential information or misuses of personal data. We have experienced in the past, and may experience in the future, cybersecurity incidents and security breaches. We may also experience cybersecurity incidents, security breaches and other incidents that may remain undetected for an extended period and therefore may have a greater impact on our products and the networks and systems used in our business. Furthermore, while we maintain cybersecurity insurance, our insurance may not cover all liabilities incurred due to a security breach or incident.

We regularly defend against and respond to cybersecurity incidents. We incur significant costs in our efforts to detect and prevent cybersecurity incidents, security breaches and other security-related incidents, and we may face increased costs in the event of an actual or perceived cybersecurity incident, security breach or other security-related incident. Despite our precautions, our facilities and systems, and those of our third-party business partners, may be vulnerable to cybersecurity incidents, security breaches, acts of vandalism and theft, computer viruses, misplaced or lost data, programming and/or human errors, or other similar events, and there is no guarantee that inadvertent or unauthorized use or disclosure will not occur or that third parties will not gain unauthorized access to this type of confidential information and personal data.

A cybersecurity incident relating to our information or systems or that of our third-party business partners, or any failure by us or our third-party business partners to effectively address, enforce and maintain our information technology infrastructure and cybersecurity requirements may result in substantial harm to our business, financial condition, results of operations and prospects, including major disruptions to business operations, loss of intellectual property, release of confidential information, alteration or corruption of data or systems, costs related to remediation or the payment of ransom and litigation, including individual claims or consumer class actions, commercial litigation, administrative, and civil or criminal investigations or actions, regulatory intervention and sanctions or fines, investigation and remediation costs, and possible prolonged negative publicity.

Failure to comply with current or future federal, state and foreign laws and regulations and industry standards relating to privacy, data protection, cybersecurity and advertising could adversely affect our business, financial condition, results of operations and prospects.

Laws, regulations and industry standards relating to privacy, data protection, cybersecurity and advertising are evolving and subject to potentially differing interpretations. These requirements may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another or may conflict with other rules or our practices. As a result, our practices may not have complied or may not comply in the future with all such laws, regulations, standards, requirements and obligations. Any failure, or perceived failure, by us to comply with our posted privacy policies or with any federal or state privacy or consumer protection-related laws, regulations, industry self-regulatory principles, industry standards or codes of conduct, regulatory guidance, orders to which we may be subject or other legal obligations relating to privacy or information security could adversely affect our reputation, brand and business, and may result in claims, fines, penalties, investigations, proceedings or actions against us by governmental entities, customers, suppliers or others or other liabilities or may require us to change our operations and/or cease using certain data.

Any such claims, proceedings, investigations or actions could harm our reputation, brand and business, force us to incur significant expenses in defense of such claims, proceedings, investigations or actions, distract our management, increase our costs of doing business, erode investor or customer confidence, result in a loss of customers or suppliers and result in the imposition of monetary penalties. We may also be contractually required to indemnify and hold harmless third parties from the costs and consequences of non-compliance with any laws, regulations or other legal obligations relating to privacy or consumer protection or any inadvertent or unauthorized use or disclosure of data that we store or handle as part of operating our business.

Federal, state and foreign governmental authorities continue to evaluate the privacy implications inherent in the use of third-party cookies, pixels, and other methods of online tracking for behavioral advertising and other purposes. The regulation of the use of these cookies and other current online tracking and advertising practices or a loss in our ability to make effective use of services that employ such technologies could increase our costs of operations and limit our ability to acquire new customers on cost-effective terms and, consequently, materially and adversely affect our business, financial condition and results of operations.

We are subject to a variety of laws and regulations in the U.S., the United Kingdom and the European Economic Area that involve matters central to our business, including privacy and data protection. California, and more than a dozen other states, have passed comprehensive privacy laws similar to the EU General Data

Protection Regulation (2016/679) (“EU GDPR”). The SEC has similarly enacted detailed cybersecurity rules that require the public disclosure of material cybersecurity incidents within four business days after we determine that an incident is material. Existing and proposed laws and regulations can be costly to comply with and can delay or impede the development of new products and services, significantly increase our operating costs, require significant time and attention of management and technical personnel and subject us to inquiries or investigations, claims or other remedies, including fines or demands that we modify or cease existing business practices. For example, administrative fines of up to the greater of €20 million and 4% of our global turnover can be imposed for breaches of the EU GDPR.

Each of these privacy, security and data protection laws and regulations, and any other such changes or new laws or regulations, could impose significant limitations, require changes to our business, or restrict our use or storage of certain data, which may increase our compliance expenses and make our business more costly or less efficient to conduct. In addition, any such changes could compromise our ability to develop an adequate marketing strategy and pursue our growth strategy effectively.

Any failure to comply with applicable laws or other obligations or any security incident or breach, whether by us, one of our third-party service providers or vendors or another third party, could have adverse effects. We cannot assure you that our vendors or other third-party service providers with access to our or our customers’ or employees’ personally identifiable and other sensitive or confidential information will not breach contractual obligations imposed by us, or that they will not experience data security breaches, which could have a corresponding effect on our business, including putting us in breach of our obligations under privacy laws and regulations and/or which could in turn adversely affect our business, results of operations and financial condition. We also cannot assure you that our contractual measures and our own privacy, data protection, and security-related safeguards will protect us from the risks associated with the third-party processing, use, storage and transmission of such information. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

The use of artificial intelligence presents risks and challenges that could adversely impact our business, financial condition, and results of operations.

We, or our third-party business partners, may use or incorporate AI technology, particularly generative AI, in certain business operations, processes, products, or services. The use of AI presents a number of opportunities for us, but also presents risks and challenges. The full extent of current or future risks related to the development and use of AI technology is not possible to predict and we may not be able to anticipate, prevent, mitigate or remediate all of the potential risks, challenges or impacts of such changes. AI could disrupt the business models, operational processes, and markets in which we operate and subject us to increased competition, which could have a material adverse effect on our business, financial condition and results of operations. Our competitors may be more successful than us in the use or implementation of new technologies, based on AI. If we are unable to adequately advance our capabilities in these areas, or do so at a slower pace than others in our industry, we may be at a disadvantage.

The use of AI in our business operations, processes, products, or services could also cause loss of intellectual property, as well as subject us to risks related to intellectual property infringement or misappropriation, data privacy and cybersecurity. The use of artificial intelligence can lead to unintended consequences, including generating content that appears correct but is factually inaccurate, misleading or otherwise flawed, or that results in unintended biases and discriminatory outcomes, which could harm our reputation and business and expose us to risks related to inaccuracies or errors in the output of such technologies.

In addition, the worldwide legal and regulatory environment relating to AI is uncertain and rapidly evolving, which could require changes in our potential use and implementation of AI technology, limit our ability to integrate AI into our business, and increase our compliance costs and the risk of non-compliance. In the U.S., states and local jurisdictions have begun to enact laws regulating AI, and additional legislative activity regulating AI is expected both in the U.S. and in other countries.

While we have an AI acceptable use policy and AI governance guidelines governing the use of AI by our personnel , contractors, vendors, and third-party business partners, we cannot guarantee that they will follow such policies when using AI or that such policies will protect us from potential liability relating to our adoption or use of AI technologies. We expect that our AI policies and procedures to continue to develop as business needs, AI-related risks, and the AI regulatory environment evolve.

Risks Related to Internal Controls over Financial Reporting

We have experienced material weaknesses in our internal control over financial reporting in the past. If we fail to maintain an effective system of integrated internal controls, we may not be able to report our financial results accurately, which could have a material adverse effect on our business, financial condition and results of operations.

We previously disclosed material weaknesses in our internal control over financial reporting in our annual report on Form 10-K for the year ended December 31, 2023. Although management implemented remediation measures during 2024 and determined that these material weaknesses were remediated as of December 31, 2024, and no material weaknesses were identified as of December 31, 2025, we have experienced material weaknesses in the past and may identify additional material weaknesses in the future.

Ensuring that we have adequate internal financial and accounting controls and procedures in place so that we can produce accurate financial statements on a timely basis is a costly and time-consuming effort that will need to be evaluated frequently. Section 404 of the Sarbanes-Oxley Act of 2002, as amended, requires public companies to conduct an annual review and evaluation of their internal controls and requires attestations of the effectiveness of internal controls by independent auditors. Evaluation of our internal controls over financial reporting may, in the future, identify material weaknesses that may cause us to be unable to report our financial information on a timely basis and thereby subject us to adverse regulatory consequences, including sanctions by the SEC or violations of Nasdaq rules. There also could be a negative reaction in the financial markets due to a loss of investor confidence in us and the reliability of our financial statements. Confidence in the reliability of our financial statements also could suffer if we or our independent registered public accounting firm were to report a material weakness in our internal controls over financial reporting. This could have a material adverse effect on our business, financial condition and results of operations and could also lead to a decline in the price of our common stock.

If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our operating results could fall below the expectations of securities analysts and investors, resulting in a decline in the market price of our common stock.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue and expenses that are not readily apparent from other sources. It is possible that interpretation, industry practice and guidance may evolve over time. If our assumptions change or if actual circumstances differ from our assumptions, our operating results may be adversely affected and could fall below the expectations of securities analysts and investors, resulting in a decline in the market price of our common stock.

Risks Related to Indebtedness and Financing

Our indebtedness could adversely affect our financial flexibility and our competitive position.

As of December 31, 2025, we owe $325.0 million on our 2028 Convertible Notes and $345.0 million on our 2031 Convertible Notes. Our level of indebtedness increases the risk that we may be unable to generate cash

sufficient to pay amounts due in respect of our indebtedness. Our indebtedness could have other important consequences to you and significant effects on our business. For example, it could:

•increase our vulnerability to adverse changes in general economic, industry and competitive conditions;

•require us to dedicate a substantial portion of our cash flow from operations to make payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate purposes;

•limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

•restrict us from exploiting business opportunities;

•make it more difficult to satisfy our financial obligations, including payments on our indebtedness;

•place us at a disadvantage compared to our competitors that have less debt; and

•limit our ability to borrow additional funds for working capital, capital expenditures, acquisitions, debt service requirements, execution of our business strategy or other general corporate purposes.

In addition, the agreement governing the Senior Secured Credit Facility (as defined herein) contains, and the agreements evidencing or governing any other future indebtedness may contain, restrictive covenants that will limit our ability to engage in activities that may be in our long-term best interests. Our failure to comply with those covenants could result in an event of default which, if not cured or waived, could result in the acceleration of all of our indebtedness. In addition, a default by us under the agreement governing the Senior Secured Credit Facility or an agreement governing any other future indebtedness may trigger cross-defaults under any other future agreements governing our indebtedness. Upon the occurrence of an event of default or cross-default under any of the present or future agreements governing our indebtedness, the lenders could elect to declare all amounts outstanding to be due and payable and exercise other remedies as set forth in the agreements. If any of our indebtedness were to be accelerated, there can be no assurance that our assets would be sufficient to repay this indebtedness in full, which could have a material adverse effect on our ability to continue to operate as a going concern.

The agreement governing the Senior Secured Credit Facility contains, and the agreements evidencing or governing any other future indebtedness may contain, financial restrictions on us and our restricted subsidiaries, including restrictions on our or our restricted subsidiaries’ ability to, among other things:

•place liens on our or our restricted subsidiaries’ assets;

•make investments other than permitted investments;

•incur additional indebtedness;

•prepay or redeem certain indebtedness;

•merge, consolidate or dissolve;

•sell assets;

•engage in transactions with affiliates;

•change the nature of our business;

•change our or our subsidiaries’ fiscal year or organizational documents; and

•make restricted payments (including certain equity issuances).

In addition, the Revolving Credit Facility (as defined herein) also includes a springing financial maintenance covenant that is tested on the last day of each fiscal quarter if the outstanding loans and certain other credit

extensions under the Revolving Credit Facility exceed 35% of the aggregate amount of commitments thereunder, subject to customary exclusions and conditions.

Our substantial indebtedness could adversely affect our financial condition.

We currently have, and we will continue to have, a significant amount of indebtedness, including the Convertible Notes. This significant amount of indebtedness could limit our ability to obtain additional financing for working capital, capital expenditures, acquisitions, debt service requirements, stock repurchases or other purposes. It may also increase our vulnerability to adverse economic, market and industry conditions, limit our flexibility in planning for, or reacting to, changes in our business operations or to our industry overall, and place us at a disadvantage in relation to our competitors that have lower debt levels. Any or all of the above events and/or factors could have an adverse effect on our results of operations and financial condition.

Further, the interest rates applicable to the Senior Secured Credit Facility are based on, and the interest rates applicable to certain debt obligations we may incur in the future may be based on, a fluctuating rate of interest determined by reference to the Secured Overnight Financing Rate (“Term SOFR”). There can be no assurance that the Federal Reserve Bank of New York will not discontinue the publication of Term SOFR, in which case interest payments on our Senior Secured Credit Facility would need to be calculated using a different index rate, or alter the manner in which Term SOFR is calculated. As a result, our interest expense could increase, in which event we may have difficulties making interest payments and our available cash flow for general corporate requirements may be adversely affected. Our interest expense could also be increased by any increase in interest rates.

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to service our substantial debt.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the Convertible Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

We may not be able to raise additional capital to execute our current or future business strategies on favorable terms, if at all, or without dilution to our stockholders.

We expect that we may need to raise additional capital to execute our current or future business strategies. However, we do not know what forms of financing, if any, will be available to us. Some financing activities in which we may engage could cause your equity interest in the Company to be diluted, which could cause the value of your stock to decrease. There can be no assurance that deterioration in credit and financial markets and confidence in economic conditions will not occur, including as a result of any increase in interest rates. A severe or prolonged economic downturn could result in a variety of risks to our business, including weakened demand for our products and harm our ability to raise additional capital when needed on acceptable terms, if at all. If the equity and credit markets continue to deteriorate, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive. If financing is not available on acceptable terms, if and when needed, our ability to fund our operations, expand our R&D and sales and marketing functions, develop and enhance our products, respond to unanticipated events, including unanticipated opportunities, or otherwise respond to competitive pressures would be significantly limited. In any such event, our business, financial condition and results of operations could be materially harmed, and we may be unable to continue our operations.

Despite our current debt levels, we may still incur substantially more debt or take other actions which would intensify the risks discussed above.

Despite our current consolidated debt levels, we and our subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in our debt instruments, some of which may be secured debt. We will not be restricted under the terms of the indenture governing the Convertible Notes from incurring additional debt, securing existing or future debt, recapitalizing our debt or taking a number of other actions that are not limited by the terms of the indenture governing the Convertible Notes that could have the effect of diminishing our ability to make payments on the Convertible Notes when due. Our Senior Secured Credit Facility restricts our ability to incur additional indebtedness, including secured indebtedness.

The conditional conversion feature of the Convertible Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the Convertible Notes is triggered, holders of Convertible Notes will be entitled to convert the Convertible Notes at any time during specified periods at their option. If one or more holders elect to convert their Convertible Notes, we would be required to settle in cash up to the converted aggregate principal amount of such Convertible Notes converted and may at our election pay the excess of any conversion obligation in cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their Convertible Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Convertible Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

The fundamental change repurchase feature of the Convertible Notes may delay or prevent an otherwise beneficial attempt to acquire us.

Certain provisions in the indenture governing the Convertible Notes may make it more difficult or expensive for a third-party to acquire us. For example, the indenture governing the Convertible Notes requires us, in certain circumstances, to repurchase the Convertible Notes for cash upon the occurrence of a fundamental change and, in certain circumstances, to increase the conversion rate for a holder that converts its Convertible Notes in connection with a make-whole fundamental change. A takeover of us may trigger the requirement that we repurchase the Convertible Notes and/or increase the conversion rate, which could make it more costly for a potential acquirer to engage in such takeover. Such additional costs may have the effect of delaying or preventing a takeover of us that would otherwise be beneficial to investors.

The capped call transactions may affect the market price of our common stock.

In connection with the pricing of the Convertible Notes, we entered into capped call transactions with several affiliates of the initial purchasers (the “Option Counterparties”). The capped call transactions are expected generally to reduce potential dilution to our common stock upon conversion of any Convertible Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted Convertible Notes, as the case may be, with such reduction and/or offset subject to a cap.

In addition, the Option Counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions and prior to the maturity of the Convertible Notes (and are likely to do so on each exercise date for the capped call transactions or following any termination of any portion of the capped call transactions in connection with any repurchase, redemption or early conversion of the Convertible Notes). This activity could cause or avoid an increase or decrease in the market price of our common stock.

We are subject to counterparty risk with respect to the capped call transactions.

The Option Counterparties are financial institutions, and we are subject to the risk that any or all of them might default under the capped call transactions. Our exposure to the credit risk of the Option Counterparties is not

secured by any collateral. Past global economic conditions have resulted in the actual or perceived failure or financial difficulties of many financial institutions. If an Option Counterparties becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under the capped call transactions with such Option Counterparties. Our exposure will depend on many factors but, generally, an increase in our exposure will be correlated to an increase in the market price and in the volatility of our common stock. In addition, upon a default by an Option Counterparties, we may suffer more dilution than we currently anticipate with respect to our common stock. We can provide no assurance as to the financial stability or viability of the Option Counterparties.

Risks Related to Ownership of Our Common Stock

Sales of substantial amounts of our common stock in the public markets, or the perception that such sales could occur, could reduce the market price of our common stock.

Sales of a substantial number of shares of our common stock in the public market, or the perception that such sales could occur, could adversely affect the market price of our common stock. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock.

We may issue common stock or equity securities senior to our common stock in the future for a number of reasons, including to finance our operations and growth plans, to adjust our ratio of debt-to-equity, to satisfy our obligations upon the exercise of options or for other reasons. Future sales or issuances of shares of our common stock or other equity securities, or the availability of shares of common stock or such other equity securities for future sale or issuance may negatively affect the trading price of our common stock. No prediction can be made as to the effect, if any, that future sales or issuance of shares of our common stock or other equity or equity-linked securities will have on the trading price of our common stock and, in turn, the Convertible Notes.

The market price for our common stock could be volatile, which could result in substantial losses for purchasers of our common stock and subject us to securities class action litigation.

The market price of our common stock could be subject to significant fluctuations. The price of our 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, many of which are beyond our control. 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:

•changes in laws or regulations applicable to our industry or offerings;

•speculation about our business in the press or the investment community;

•price and volume fluctuations in the overall stock market;

•volatility in the market price and trading volume of companies in our industry or companies that investors consider comparable;

•share price and volume fluctuations attributable to inconsistent trading levels of our shares;

•our ability to protect our intellectual property and other proprietary rights and to operate our business without infringing, misappropriating or otherwise violating the intellectual property and other proprietary rights of others;

•sales of our common stock by us or our significant stockholders, officers and directors;

•success of competitive products or services;

•the public’s response to press releases or other public announcements by us or others, including our filings with SEC, announcements relating to litigation or significant changes to our key personnel;

•the effectiveness of our internal controls over financial reporting;

•changes in our capital structure or dividend policy, including as a result of future issuances of securities, sales of large blocks of common stock by our stockholders, potential resales of a substantial number of additional shares of common stock received upon conversion of the Convertible Notes, or our incurrence of debt;

•our entry into new markets;

•tax developments in the U.S., Europe or other markets;

•strategic actions by us or our competitors, such as acquisitions or restructurings;

•changes in accounting principles;

•geopolitical, macroeconomic and other market conditions unrelated to our operating performance or the operating performance of our competitors, a pandemic or other epidemic, the military conflict in Ukraine, conflict in the Middle East, attacks on a shipping lane in the Red Sea and inflation and interest rates; and

•the other factors described in this “Risk Factors” section.

Further, in recent years the U.S. securities markets have experienced significant 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.

In addition, in the past, class action litigation has often been instituted against companies whose securities have experienced periods of volatility in market price. Securities litigation brought against us following volatility in our stock price, regardless of the merit or ultimate results of such litigation, could result in substantial costs, which would harm our financial condition and operating results and divert management’s attention and resources from our business.

We have issued and may in the future issue preferred stock whose terms could adversely affect the voting power or value of our common stock.

The certificate of incorporation governing our Series A Redeemable Perpetual Preferred Stock of the Company, par value $0.001 per share (the “Series A Shares”) authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our common stock respecting dividends and distributions, as our board of directors may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of our common stock.

Provisions in our certificate of incorporation and bylaws, may have the effect of delaying or preventing a change of control or changes in our management.

Our certificate of incorporation and bylaws contain provisions that could depress the trading price of our common stock by discouraging, delaying or preventing a change of control of our Company or changes in our management that the stockholders of our Company may believe advantageous. These provisions include:

•authorizing “blank check” preferred stock that our board of directors could issue to increase the number of outstanding shares to discourage a takeover attempt;

•providing for a classified board of directors with staggered, three-year terms, which could delay the ability of stockholders to change the membership of a majority of our board of directors;

•not providing for cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;

•limiting the ability of stockholders to call a special stockholder meeting;

•prohibiting stockholders from acting by written consent;

•establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings;

•the removal of directors only for cause and only upon the affirmative vote of the holders of at least 66 2/3% in voting power of all the then-outstanding shares of our common stock of entitled to vote thereon;

•providing that our board of directors is expressly authorized to amend, alter, rescind or repeal our bylaws; and

•requiring the affirmative vote of holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of common stock to amend provisions of our certificate of incorporation relating to the management of our business, our board of directors, stockholder action by written consent, calling special meetings of stockholders, competition and corporate opportunities, Section 203 of the Delaware General Corporation Law (the “DGCL”), forum selection and the liability of our directors, or to amend, alter, rescind or repeal our bylaws.

In addition, we are not 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.

Furthermore, our certificate of incorporation provides that the federal district courts of the U.S. is the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (the “Securities Act”), but that the forum selection provision will not apply to claims brought to enforce a duty or liability created by the Exchange Act.

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the DGCL, our certificate of incorporation or our bylaws; any action to interpret, apply, enforce or determine the validity of our certificate of incorporation or our bylaws; any action asserting a claim against us that is governed by the internal affairs doctrine; or any action asserting an “internal corporate claim” as defined in Section 115 of the DGCL. The choice of forum provision 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 provision contained in our 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 do not intend to pay any cash distributions or dividends on our common stock in the foreseeable future.

We have never declared or paid any distributions or dividends on our common stock, except the special distribution, see Note 11 – Redeemable Perpetual Preferred Stock. We currently intend to retain any future earnings and do not expect to pay any cash distributions or dividends on our common stock in the foreseeable future. Any future determination to declare cash distributions or dividends on our common stock will be made at the discretion of our board of directors, subject to applicable laws and provisions of our debt instruments and organizational documents, 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.

General Risk Factors

Changes in laws and regulations, including changes to tax laws or regulations that are applied adversely to us or our customers could materially adversely affect our business, financial condition, results of operations and prospects.

Laws and regulations continually change as new legislation is passed and new interpretations of the law are issued or applied. Laws and regulations, such as 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 European Union member states have enacted the OECD Pillar Two Directive implementing a 15% global minimum tax, with various provisions effective beginning in 2024 and 2025. Although the U.S. has not enacted domestic legislation to implement Pillar Two, recent OECD administrative guidance issued on January 5, 2026 introduces a Side‑by‑Side (SbS) Safe Harbor under which U.S.-parented multinational groups—currently the only jurisdiction qualifying for this regime—may elect exemption from both the Income Inclusion Rule (IIR) and Undertaxed Profits Rule (UTPR) starting in 2026. U.S.-parented companies remain subject to Qualified Domestic Minimum Top‑Up Taxes (QDMTTs) imposed by foreign jurisdictions and must complete full Pillar Two computations and GloBE Information Return (GIR) filings for tax years 2024 and 2025, as the SbS Safe Harbor is not retroactive. Many countries in which we operate have adopted or are in the process of adopting Pillar Two legislation, and these rules may continue to impact our effective tax rate and future income tax expense.

Economic, political and market conditions could adversely affect our business, results of operations and financial condition, including our revenue growth and profitability, which in turn could adversely affect our stock price.

Geopolitical and macroeconomic developments such as the global or regional economic effects resulting from the current Russia-Ukraine war and ongoing instability in the Middle East (including, but not limited to, the Israel-Iran conflict and disruptions in the transportation of goods through the Suez canal and to shipping in the Red Sea), inflation and related economic curtailment initiatives, evolving trade policies between the U.S. and international trade partners, or the occurrence of similar events in other countries that lead to uncertainty or instability in economic, political or market conditions could negatively affect our business, operating results, financial condition and outlook, which, in turn, could adversely affect our stock price. Political issues and conflicts could have a material adverse effect on our results of operations and financial condition if they escalate into geographies in which we do business or obtain our components. A local conflict, such as the Russian-Ukrainian war or the conflict in the Middle East, could also have a significant adverse impact on regional or global macroeconomic conditions, give rise to regional instability or result in heightened economic

tariffs, sanctions and import export restrictions in a manner that adversely affects us, including to the extent that any such actions cause material business interruptions or restrict our ability to conduct business with certain suppliers. Additionally, such conflict or sanctions may significantly devalue various global currencies and have a negative impact on economies in geographies in which we do business. Any general weakening of, and related declining corporate confidence in, the global economy could cause current or potential customers to reduce or eliminate their budgets and spending, resulting in delayed, decreased, or canceled projects with us, which could have a negative effect on our business, operating results and financial condition.

Our business is subject to the risks of severe weather events, natural disasters and other catastrophic events.

Our customers and suppliers are located in the U.S. and around the world. A severe weather event or other catastrophe could significantly impact our supply chain by causing delays in the shipping and delivery of our materials, components and products which may, in turn, cause delays in our customers’ solar projects. Our customers’ ability to install solar energy systems is also affected by weather, such as during the winter months in colder climates.

Any damage and disruption in any locations in which our customers have solar projects which are caused by severe weather events (such as extreme cold weather, hail, hurricanes, tornadoes and heavy snowfall), seismic activity, fires, floods and other natural disasters or catastrophic events could result in a delay or even a complete cessation of our worldwide or regional operations and could cause severe damage to our products and equipment used in our solar projects. Even if our tracker products are not damaged, severe weather, natural disasters and catastrophic events may cause damage to the solar panels that are mounted to our tracker products, which could result in decreased demand for our products, loss of customers and the withdrawal of coverage for solar panels and solar tracking systems by insurance companies. Any of these events would negatively impact our ability to deliver our products and services to our customers and could result in reduced demand for our products and services, and any damage to our products and equipment used for our solar projects could result in large warranty claims which could, individually or in the aggregate, exceed the amount of insurance available to us, all of which would have a material adverse effect on our financial condition and results of operations. These events may increase in frequency and severity due to the effects of climate change.

The severity and duration of public health threats could materially impact our business, financial condition, and results of operations.

The extent to which public health threats (including pandemics) could impact us in the future is highly uncertain and unpredictable, and will depend largely on subsequent developments, including but not limited to: (i) the severity and duration of any public health threat; (ii) measures taken to contain the spread of any public health threat, such as restrictions on travel and gatherings of people and temporary closures of or limitations on businesses and other commercial activities; and (iii) the timing and nature of policies implemented by governmental authorities. As a result of any public health threat and any related containment measures, we, our suppliers, or customers may be subject to significant risks, including to supply chain and business operations, which have the potential to materially and adversely impact our business, financial condition, and results of operations.

We are subject to a variety of litigation and other legal and regulatory proceedings in the course of our business that may adversely affect our business and financial results.

We are subject to a variety of litigation and other legal and regulatory proceedings in the course of our business, including claims or counterclaims for damages. The types of claims made in lawsuits include claims for compensatory damages, punitive and consequential damages (and in some cases, treble damages) and/or injunctive relief. The defense of these lawsuits can divert our management’s attention, can result in significant expenses in defending these lawsuits, and we can be required to pay damage awards or settlements or

become subject to equitable remedies that adversely affect our business and financial statements. Moreover, any insurance or indemnification rights that we may have may be insufficient or unavailable to protect us against such losses. Because most contingencies are resolved over long periods of time, new developments (including litigation developments, the discovery of new facts, changes in legislation and outcomes of similar cases), changes in assumptions or changes in the Company’s strategy in any given period can require us to adjust the loss contingency estimates that we have recorded in our financial statements, record estimates for liabilities or assets previously not susceptible of reasonable estimates or pay cash settlements or judgments. Any of these developments may adversely affect our business and financial results in any particular period.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Risk Management and Strategy

Our commercial success depends on developing, implementing, and maintaining robust cybersecurity measures to safeguard our information technology systems and protect the confidentiality, integrity and availability of our data. Accordingly, we have adopted processes designed to identify, assess and mange material risks from cybersecurity threats.

Managing Material Risks & Integrated Enterprise Risk Management

We continue to strategically integrate cybersecurity risk management into our broader enterprise risk management program to promote a company-wide culture of cybersecurity risk management. Our enterprise risk management project team is working closely with our IT department to evaluate and address cybersecurity risks in alignment with our business objectives and operational needs while building out a framework to monitor those risks and integrate objectives into our broader strategic plan.

Engaging Third Parties on Risk Management

Given the complexity and evolving nature of cybersecurity threats, we have engaged a range of external experts, including cybersecurity assessors, consultants, and auditors in evaluating, testing, and improving our risk management systems. These partnerships enable us to leverage specialized knowledge and insights and includes regular evaluations, threat assessments, and consultation on security enhancements.

Overseeing Third Party Risk

The need to govern third party business partners poses significant challenges, and as a result we have implemented processes to oversee and manage these risks. Our procedures contemplate conducting security assessments of all third-party software vendors that are proportional to the risks present, ideally before or soon after engagement, and periodically thereafter, in order to mitigate risks related to data breaches or other cybersecurity incidents originating from third parties.

Risks from Cybersecurity Threats

We are not aware of any risks from cybersecurity threats, including as a result of previous cybersecurity incidents, that have materially affected, or are reasonably likely to materially affect, our business strategy, results of operations, or financial condition. However, we cannot assure that our business strategy, results of operations and financial condition will not be materially affected in the future by cybersecurity risks or future cybersecurity incidents.

Governance

Our board of directors is aware of the critical nature of managing risks associated with cybersecurity threats. In recognition of the significance of these threats to our operational integrity and shareholder confidence, our board of directors has established oversight mechanisms to ensure effective governance in managing risks associated with cybersecurity threats.

Board of Directors Oversight

The Nominating and Corporate Governance Committee of our board of directors bears primary responsibility for the oversight of cybersecurity risks. The Nominating and Corporate Governance Committee was briefed on cybersecurity risks and any material cybersecurity incidents four times in 2025 by our Chief Information Officer and our Chief Financial Officer, as further described below. The Nominating and Corporate Governance Committee is composed of directors equipped with diverse skills needed to oversee the difference facets of cybersecurity risks effectively, including risk management, public company leadership, innovation and technology, corporate governance and finance.

Management’s Role Managing Risk

The Chief Information Officer and the Chief Financial Officer are responsible for updating the Nominating and Corporate Governance Committee on cybersecurity risks and our mitigation strategies. They provide regular updates to the Nominating and Corporate Governance Committee, as well as comprehensive briefings at least once per year and appropriate briefings during any potentially material cybersecurity incident. These briefings encompass a broad range of topics, including:

•results of internal assessments and evaluations by third parties;

•the current cybersecurity landscape and emerging threats;

•the status of ongoing cybersecurity initiatives and strategies;

•incident reports and lessons learned from any cybersecurity events; and

•compliance with regulatory requirements and industry standards.

In addition to regular scheduled meetings, the Nominating and Corporate Governance Committee, our Chief Information Officer and our Chief Financial Officer maintain an ongoing dialogue regarding emerging or potential cybersecurity risks. Together, they receive periodic updates on significant developments in the cybersecurity landscape to support proactive and responsive board oversight. The Nominating and Corporate Governance Committee actively participates in strategic decisions related to cybersecurity, reviewing and offering guidance on major initiatives and any potentially material cybersecurity incident. This involvement ensures that cybersecurity considerations are integrated into our broader strategic objectives.

Risk Management Personnel

Primary responsibility for assessing, monitoring and managing our cybersecurity risks rests with our Chief Information Officer. Our Chief Information Officer has managed cybersecurity and information security at Array for the past six years and has over 15 years of total experience as an information technology executive for publicly listed companies. Our Chief Information Officer holds B.S. degrees in finance and computer science from Arizona State University as well as a M.B.A. from Western International University. He manages a team with over 40 years of combined experience in cybersecurity. Our Chief Information Officer reports to our Chief

Financial Officer, and both are responsible for updating the Chief Executive Officer, the Nominating & Corporate Governance Committee, and our board of directors on cybersecurity issues.

Ongoing Education and Monitoring

The Chief Information Officer leads our cybersecurity team, which remains current with the latest developments in cybersecurity, including potential threats and innovative risk management techniques. This ongoing education is crucial for the effective prevention, detection, mitigation and remediation of cybersecurity threats and incidents. The Chief Information Officer implements and oversees processes for the regular monitoring of our information systems. This includes the deployment of advanced security measures and regular system evaluations, including penetration testing, to identify potential vulnerabilities. In the event of a cybersecurity incident, we are equipped with a well-defined incident response plan. This plan includes immediate actions to mitigate the impact and long-term strategies for remediation and prevention of future incidents.

Reporting to the Board of Directors

The Chief Information Officer regularly informs the Chief Financial Officer and Chief Executive Officer of all significant aspects related to cybersecurity risks and incidents. This ensures that the highest levels of management are kept abreast of the cybersecurity posture and potential significant risks facing the Company. Furthermore, significant cybersecurity matters, and strategic risk management decisions are escalated to the Nominating and Corporate Governance Committee of our board of directors and, in certain cases, the board itself, ensuring that they have comprehensive oversight and can provide guidance on any potentially material cybersecurity incident.

Item 2. Properties

To support our global operations, we occupy approximately 4.0 million square feet of office, manufacturing, and warehouse space in the U.S. and internationally.

U.S. Properties

Our corporate headquarters is located in Albuquerque, New Mexico. It consists of approximately 11,600 square feet of office space and approximately 283,000 square feet of manufacturing, warehousing, and shipping facilities, of which we own approximately 69,600 square feet. We also lease approximately 74,000 square feet of office space in Chandler, Arizona for our corporate staff. With the APA Acquisition, we added approximately 49,000 square feet of leased office space in Ridgeville Corners, Ohio. To support our U.S. operations, we lease approximately 2.5 million square feet of warehousing and manufacturing space, inclusive of APA, across various facilities in the U.S., including Kansas, Tennessee, Ohio, Texas, Nevada, New Mexico, and Connecticut. Our U.S. facilities are primarily used by our Array Legacy segment.

In May 2024, we entered into a triple-net lease for an approximately 216,000-square-foot mixed-use facility in Bernalillo County, New Mexico. The facility includes approximately 176,000 square feet of manufacturing space and approximately 40,000 square feet of office and laboratory space. We took control of the facility in the fourth quarter of 2025 and construction is expected to be completed in March 2026. We expect to commence production at the facility in the first half of 2026.

International Properties

To support our international operations, we own and lease properties in Spain and Brazil. In Spain, we own approximately 2,000 square feet of office space and lease approximately 16,000 square feet of office space for our STI corporate staff working under our STI Operations segment. For our international manufacturing and warehousing needs, we own approximately 27,000 square feet and lease approximately 40,000 square feet in

Spain. In Brazil, we lease approximately 11,000 square feet of office space and lease approximately 610,000 square feet of warehousing and manufacturing space. Our Spain and Brazil facilities are primarily used by our STI Operations segment.

We believe our existing facilities 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.

Item 3. Legal Proceedings

From time to time we may be involved in claims arising in the ordinary course of business. To our knowledge, other than the cases described below, no material legal proceedings, governmental actions, investigations or claims are currently pending against us or involve us that, in the opinion of our management, could reasonably be expected to have a material adverse effect on our business and financial condition. The Company believes the claims alleged in the actions discussed below are without merit and intends to continue to vigorously defend its position in these matters.

The Company, in the normal course of business, is subject to claims and litigation. The Company reviews the status of each matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, the Company would accrue a liability for the estimated loss.

Plymouth Class Action

On May 14, 2021, a putative class action (the “Plymouth Action”) was filed in the U.S. District Court for the Southern District of New York against the Company and certain officers and directors alleging violations of Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5, promulgated thereunder, and Sections 11, 12(a)(2) and 15 of the Securities Act. The complaint alleges misstatements and/or omissions in the Company’s registration statements and prospectuses related to the Company’s October 2020 initial public offering, the Company’s December 2020 offering, and the Company’s March 2021 offering during the putative class period of October 14, 2020 through May 11, 2021. A consolidated amended class action complaint was filed on December 7, 2021 with additional allegations regarding misstatements and/or omissions in: (i) in the Company’s annual report on Form 10-K and associated press release announcing results for the fourth quarter and full fiscal year 2020; and (ii) in the Company’s November 5, 2020 and March 9, 2021 earnings calls.

On June 30, 2021, a substantially similar second putative class action was filed in the Southern District of New York against the Company and certain officers and directors alleging violations of Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5, promulgated thereunder, and Sections 11 and 15 of the Securities Act, which was consolidated with the Plymouth Action. The plaintiffs in the consolidated action seek an award of damages and the interest thereon, any injunctive relief the court deems just and proper, and reasonable costs of bringing the litigation, including attorneys’ fees.

All defendants in the Plymouth Action, including the Company, moved to dismiss the consolidated amended complaint. On May 19, 2023, the court granted the Company’s motion to dismiss and, on July 5, 2023, denied a request from the Plymouth Action plaintiffs for leave to amend the consolidated amended complaint and dismissed the Plymouth Action in its entirety with prejudice.

On August 4, 2023, the lead plaintiffs filed a notice of appeal of the court’s dismissal of the consolidated amended complaint to the U.S. Court of Appeals for the Second Circuit. After full briefing, the court of appeals heard oral argument on June 26, 2024 and the case is still pending decision by the court.

Derivative Complaints

Southern District of New York

On July 16, 2021, a verified derivative complaint was filed in the Southern District of New York against certain officers and directors of the Company. The complaint alleges: (i) violations of Section 14(a) of the Exchange Act for misleading proxy statements; (ii) breach of fiduciary duty; (iii) unjust enrichment; (iv) abuse of control; (v) gross mismanagement; (vi) corporate waste; (vii) aiding and abetting breach of fiduciary duty; and (viii) contribution under Sections 10(b) and 21D of the Exchange Act. The derivative plaintiff in this action seeks: declaratory relief; an award of compensatory damages to the Company, with interest; restitution from the defendants; an order directing the Company to reform its corporate governance and internal procedures; and the costs and disbursements of the action, including attorneys’ fees.

On July 30, 2021, a second verified derivative complaint was filed in the Southern District of New York against certain officers and directors of the Company. The complaint alleges: (i) violations of Section 14(a) of the Exchange Act for causing the issuance of a false/misleading proxy statement; (ii) breach of fiduciary duty; and (iii) aiding and abetting breaches of fiduciary duty. The derivative plaintiff in this action seeks the same relief sought in the verified derivative complaint filed in the Southern District of New York on July 16, 2021.

On August 24, 2021, the Southern District of New York derivative actions were consolidated, and the court appointed co-lead counsel. The consolidated cases remain stayed pending the outcome of the appeal of the Plymouth Action.

Delaware Court of Chancery

On August 3, 2022, a verified derivative complaint was filed in the Court of Chancery of the State of Delaware against certain officers and directors of the Company, asserting claims for: (i) breach of fiduciary duty; and (ii) unjust enrichment. The derivative plaintiff in this action seeks: an award of compensatory damages in favor of the Company; restitution from the defendants and disgorgement of profits, benefits, and other compensation obtained by the defendants; an order directing the Company to reform its corporate governance and internal procedures; equitable or injunctive relief as permitted by law and equity; and the costs and disbursements of the action, including attorneys’ fees.

On August 11, 2022, a second verified derivative complaint was filed with the Court of Chancery against certain officers and directors of the Company, asserting claims for: (i) breach of fiduciary duty; (ii) aiding and abetting breaches of fiduciary duty; (iii) waste of corporate assets; (iv) unjust enrichment; (v) insider selling; and (vi) aiding and abetting insider selling. The derivative plaintiff in this action seeks: declaratory relief; an award of compensatory damages in favor of the Company; disgorgement of profits obtained from certain sales of Company stock by certain of the defendants; establishment of a constructive trust over certain amounts obtained by certain of the defendants; and the costs and disbursements of the action, including attorneys’ fees.

On September 2, 2022, the derivative cases with the Court of Chancery were consolidated and the court appointed co-lead counsel. The consolidated cases remain stayed pending the outcome of the appeal of the Plymouth Action.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our financial statements and the related notes and other financial information included in this Annual Report on Form 10-K. In addition to historical financial information, the following discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those discussed under the sections of this Annual Report on Form 10-K captioned “Forward-Looking Statements” and “Risk Factors.”

Overview

We are a leading global provider of solar tracking technology and fixed-tilt systems to utility-scale and distributed generation customers who construct, develop, and operate solar PV sites. With solutions engineered to withstand harsh weather conditions, Array’s high-quality solar trackers, fixed-tilt systems, software platforms, foundation solutions, and field services combine to optimize energy production and deliver value to our customers for the entire lifecycle of a project.

Trackers move solar panels throughout the day to maintain an optimal orientation to the sun, which significantly increases energy production. Solar energy projects that use trackers typically generate more energy and deliver a lower LCOE than projects that use “fixed tilt” mounting systems, which do not move. Hybrid sites utilizing trackers and fixed-tilt can be utilized to optimize productivity based on the topography, geography, and environment. The vast majority of ground mounted solar systems in the U.S. use trackers.

Our flagship tracker, DuraTrack®, uses a patented design that allows one motor to drive multiple rows of solar panels through articulated driveline joints. To avoid infringing on our U.S. patent, our competitors must use designs that we believe are inherently less efficient and reliable. For example, our largest competitor’s design requires one motor for each row of solar panels. As a result, we believe our products have greater reliability, lower installation costs, reduced maintenance requirements and competitive manufacturing costs. Our core U.S. patent is on a linked-row, single-driving apparatus that rotates multiple tracker rows connected by an articulating drive shaft. This patent does not expire until February 5, 2030.

With our acquisition of STI in January 2022, we added a dual-row tracker design to our product portfolio, the Array STI H250. This tracker uses one motor to drive two connected rows and is ideally suited for sites with irregular and highly angled boundaries or fragmented project areas.

Our third tracker product, OmniTrack, which was introduced in September 2022, requires significantly less grading and civil works permitting prior to installation in addition to accommodating uneven terrain.

With the APA Acquisition in August 2025, we added a portfolio of fixed-tilt and foundation solutions, including the APA Titan and APA Titan Duo™ racking systems and the APA A-Frame™ Interface foundation. These products deliver adaptable designs for utility-scale projects, offering flexibility for challenging terrain, high snow loads, and large-format modules while streamlining installation and reducing material costs.

We sell our products to solar developers, independent power producers, utilities, and EPCs that build solar energy projects, often under master supply agreements or multi-year procurement contracts. During the year ended December 31, 2025, we derived 81% and 19% of our revenues from customers in the U.S. and the rest of the world, respectively. From the founding of Array through December 31, 2025, we had shipped approximately 96 gigawatts of trackers to customers worldwide.

Acquisition of APA Solar

On the Closing Date, our wholly owned subsidiary STINorland USA, Inc., a California corporation, the Buyer, completed the APA Acquisition, pursuant to the terms of the Purchase Agreement. The cash paid as of the Closing Date was $159.9 million, net of $10.1 million in preliminary and customary purchase price adjustments, which includes $6.2 million to retire debt. For U.S. GAAP purposes, the aggregate cash consideration paid was approximately $166.1 million, subject to final post-closing adjustment. We expect to finalize customary post-closing adjustments by June 2026. The Purchase Agreement also includes an earnout provision estimated to have a fair value of approximately $19.3 million as of the Closing Date (the “Earnout Consideration”), which is included in the purchase consideration, under which the Seller may receive shares of Company common stock, or equivalent cash value at the Buyer’s discretion, based upon APA’s achievement of certain financial performance targets during the three-year period ending on September 30, 2028. As a result, the purchase consideration for the APA Acquisition totaled approximately $185.4 million. Subject to the terms and conditions set forth in the Purchase Agreement, the Company has also agreed to pay aggregate deferred consideration of approximately $40.0 million payable in three installments over a two-year period based on service within five business days after the first and second anniversaries from the Closing Date and as set forth in Note 3 - Acquisition (the “Deferred Consideration”). For further discussion of the Earnout Consideration and Deferred Consideration, see “—APA Acquisition Earnout Consideration and Deferred Consideration” below.

The amounts recorded as of December 31, 2025 are preliminary, as the Company is finalizing working capital, post-closing, and other customary adjustments. These preliminary estimates are subject to change within the measurement period (defined as the twelve months following the Closing Date) and related accounting adjustments may be materially different, as the Company obtains additional information on these matters and as additional information is made known during the post-acquisition measurement period. As a result of further refining its estimates and assumptions since the date of the acquisition, the Company recorded measurement period adjustments to the initial opening balance sheet. There were no measurement period adjustments materially impacting earnings that would have been recorded in previous reporting periods if the adjustments had been recognized as of the acquisition date.

In connection with the APA Acquisition, the Company has lease agreements for offices, manufacturing facilities and warehouses located in Ohio and Connecticut. Of these lease agreements, five are with related parties owned by certain members of APA's management team.

Expenses related to these operating lease agreements are allocated based on usage to Cost of product and service revenue or General and administrative expenses in the consolidated statements of operations. Total costs related to these operating lease agreements were $1.2 million for the year ended December 31, 2025.

2.875% Convertible Senior Notes due 2031

On June 27, 2025, we completed a private placement of $345 million in aggregate principal amount of the 2031 Convertible Notes, resulting in net proceeds of $334.6 million after deducting initial purchasers’ discounts and offering expenses. The 2031 Convertible Notes were issued pursuant to an indenture, dated June 27, 2025, between the Company and U.S. Bank Trust Company, National Association, as trustee.

The 2031 Convertible Notes are senior unsecured obligations of the Company and will mature on July 1, 2031, unless earlier converted redeemed or repurchased. Interest is payable semiannually in arrears at a rate of 2.875% per year on January 1 and July 1 of each year, beginning on January 1, 2026.

Research and Development

R&D costs are included within General and administrative expenses in the accompanying consolidated statements of operations. We incur R&D costs during the process of researching and developing new products and significant enhancements to existing products. R&D costs are a subset of our total engineering spend and consist primarily of personnel-related costs associated with our team of internal engineers, third-party consultants, materials and overhead. We expense these costs as incurred. Total engineering expense was $18.7 million, $17.0 million and $16.7 million during the years ended December 31, 2025, 2024 and 2023, respectively, of which $9.9 million, $6.7 million and $8.5 million were related to R&D activities we performed during the same period, respectively.

Factors Affecting Results of Operations

Project Timing

Because we recognize revenue on projects as legal title to equipment is transferred from us to the customer, any delays in large projects from one quarter to another for any reason may cause our results of operations for a particular period to fall below expectations and make the timing of revenue difficult to forecast. Our end-users’ ability to install solar energy systems has been affected by a number of factors including:

•Weather. Inclement weather can affect our customers’ ability to install their systems, particularly in the northeastern U.S., Europe and Brazil. In addition, weather delays can adversely affect our logistics and operations by causing delays in the shipping and delivery of our materials.

•The U.S. interest rate environment. We have had customers delay planned installations or look to renegotiate power purchase agreements (“PPAs”) to improve project returns based on various rate environments. For example, in anticipation of interest rate reductions and more favorable project financing conditions later in 2024, some customers delayed installations. While the Federal Reserve began lowering interest rates in the second half of 2024, the timing and impact of subsequent rate adjustments during 2025 continued to create additional considerations for our customers, and there are varying outlooks on whether additional rate cuts may occur. Customers must weigh this uncertainty in conjunction with other macroeconomic factors when assessing the returns and timing for relevant projects.

•Availability of necessary equipment. We have a broad portfolio of customer relationships including presence with most Tier 1 utilities in the U.S. Each utility has unique specifications for access to its grid, which are generally not consistent across the industry. As the supply of renewables projects has increased, shortages and long lead-times in the supply of switches, transformers and high-voltage breakers used in the interconnection of utility scale solar power plants to the grid, has historically affected the timing and completion of these projects, including for some of our customers.

•Macroeconomic factors. There has been a rapid depreciation of the Brazilian real in conjunction with existing pricing pressures on energy in the Brazilian market. Due to these dynamics, the economic cases for the PPAs, for many solar projects have become less attractive for our customers. Many of the developers in Brazil of these projects continue to signal delays as they renegotiate the pricing of these PPAs. In addition, our results will also be impacted by tax incentives we can recognize, for example the Brazil value-added tax benefit, Imposto sobre Circulação de Mercadorias e Servicos (“ICMS”), which will be fully phased out in 2033. As a result, we are focused on reducing costs and better aligning our organization, including the size thereof, in Brazil with the current market conditions.

It is uncertain what impact new or existing tariffs, trade restrictions or retaliatory actions may have on us, the solar industry and our customers. An escalation in trade tensions or the implementation of broader tariffs, trade restrictions or retaliatory measures on our products or components originating from countries outside the U.S. could adversely impact our ability to source necessary components, manufacture products at competitive cost, or sell our products at prices customers are willing to pay. Any such developments could materially and adversely affect our business operations, results of operations and cash flows.

•Local permitting. If our customers cannot receive permitting for their projects, they are unable to begin and ultimately complete them in a timely manner. A dramatic increase in solar and battery storage sites has increased the average permitting time in many geographies in which our customers operate.

Impact of OBBB

On July 7, 2025, President Trump issued an executive order instructing Treasury to issue updated guidance, including on commencement of construction, within 45 days. On August 15, 2025, Treasury and the IRS issued Notice 2025-42 consistent with the executive order, which eliminates the 5% safe harbor for utility-scale solar projects and only allows the physical work test to determine when a project begins construction. If solar developers are unable to satisfy the physical work test, our business, financial condition, and results of operations could be adversely affected.

Section 45X Credit

key suppliers around sharing the economic benefits of section 45X credits associated with torque tube and structural fasteners. We continue to pursue additional agreements for splitting the economic benefits of section 45X with suppliers for parts we do not manufacture internally. In addition, during the second quarter of 2024, we concluded that certain parts manufactured by the Company qualify for the section 45X advanced production credits. Refer to Note 2 – Summary of Significant Accounting Policies in the accompanying notes to our consolidated financial statements included in this Annual Report on Form 10-K for a discussion on how we account for these incentives and amounts recognized for the periods presented.

Domestic Content Safe Harbor Guidance

The IRS issued Notice 2023-38 in May 2023 setting forth guidance on the domestic content bonus tax credits under the IRA. Uncertainties existed under this guidance, like whose costs would be used (the manufacturer’s cost, a vendor’s cost to acquire, etc.) and how to define manufactured product components associated with trackers. In May 2024, the IRS issued Notice 2024-41 setting forth further guidance on the domestic content bonus tax credits, including a safe harbor method for calculating domestic content percentages. On January 16, 2025, the IRS released Notice 2025-08, which modified Notice 2023-38 and Notice 2024-41, as well as introduced an updated elective safe harbor method for use in lieu of provisions of the adjusted percentage rule provided in Notice 2023-38 for calculating the domestic content bonus credit amounts applicable for certain qualified facilities and energy projects. Notice 2024-41 and Notice 2025-08 and the updated definitions described therein clarified certain pre-existing uncertainty in the industry, but also introduced new uncertainties. These uncertainties have and could continue to cause our customers to delay projects as they navigate the existing guidance in qualifying for the tax credit and possibly wait for further clarity. If these financial benefits vary significantly from our assumptions, our business, financial condition, and results of operations could be adversely affected.

Structured Cost Management

We actively manage the risk from certain types of customer contracts, including, for example, multi-year contracts that require fixed pricing or pricing tied to certain commodity indices. Depending on the totality of the circumstances and our ability to mitigate risk, we may or may not pursue such contractual arrangements. Where we decline, this may have the effect of driving certain customers or projects to our competitors. We believe this is the right way to manage a high-quality portfolio and drive consistent margins over time.

Impact of the Ongoing Russia-Ukraine War

The ongoing Russia-Ukraine war has reduced the availability of material that can be sourced in Europe and, as a result, increased logistics costs for the procurement of certain inputs and materials used in our products. We do not know the ultimate severity or duration of the conflict, but we continue to monitor the situation and evaluate our procurement strategy and supply chain to reduce any negative impact on our business, financial condition, and results of operations.

Impact of Disruption of Key Shipping Lanes

In the recent past, we have seen disruptions of container shipping traffic through the Red Sea create port congestion, especially in Asia, and cause many shipping companies to pause shipments through the Suez Canal and the Red Sea as a result of attacks against commercial vessels in the area, affecting transit times, capacity, and shipping costs for routes connecting the rest of the world with Asia. To address the persisting challenges arising from prolonged transit times, we have increased our local sourcing efforts where feasible within certain regions. These measures aim to reduce delays to get the product to project sites on time. There is still uncertainty on how long disruptions and the severity of their impact on our operations may last, but we continue to monitor such situations and evaluate our procurement and supply chain strategies, to reduce any negative impact on our business, financial condition, and results of operations.

Inflation

Inflationary pressure may continue to negatively impact our results of operations in the near-term. To mitigate these pressures on our business, and the volatility in steel and aluminum prices, we have continued to accelerate our productivity initiatives, expand our supplier base, and execute on our overhead cost-containment practices.

Impact of AD/CVD Petitions and Determinations

On August 18, 2023, the USDOC issued final affirmative determinations of circumvention with respect to certain CSPV cells and modules produced in Cambodia, Malaysia, Thailand and Vietnam using parts and components from China. As a result, certain CSPV cells and modules from Cambodia, Malaysia, Thailand and Vietnam are now subject to AD/CVD orders on CSPV cells and modules from China that have been in place since 2012. Subject to certain certification and utilization conditions, imports of CSPV cells and modules covered by the circumvention determinations that entered the U.S. during the two-year period prior to June 6, 2024—which had been authorized by the former President Biden on June 2022—were not subject to AD/CVD cash deposit or duty requirements. Imports of CSPV cells and modules from the four Southeast Asian countries covered by the circumvention determination that entered the U.S. on or after June 6, 2024 are subject to AD/CVD cash deposit requirements of the China AD/CVD orders and, possibly, final AD/CVD duty liability. Cash deposit rates for CSPV modules covered by the China AD/CVD orders vary significantly depending on the producer and exporter of the modules and may amount to over 250% of the entered value of the imported merchandise.

Additionally, in October 2023, a coalition of U.S. aluminum extruders and a labor union filed AD/CVD cases on

aluminum extrusions from fifteen countries. The USDOC has initiated investigations based on the petitions. Certain components in our trackers, including certain clamps, U-joints, and bearing housings are made using extruded aluminum. In September 2024, the USDOC released its final determination from their investigations against aluminum extrusions from multiple countries. On October 30, 2024, USITC voted to find no injury in its pending AD/CVD investigation, meaning that the USDOC’s AD/CVD orders will not go into effect. The coalition of petitioners may still appeal the USITC’s decision, and we will continue to monitor developments in the appeal process. If the USITC’s decision is overturned on appeal, the imposition of AD/CVD orders could

negatively impact our business, financial condition, and results of operations.

U.S. Trade Policy and Executive Orders

On February 1, 2025, President Trump issued executive orders directing the U.S. to impose new tariffs on imports from Canada, Mexico, and China, to take effect on February 4, 2025. On February 3, 2025, President Trump announced his intention to pause these tariffs on Canada and Mexico for a 30-day period. The tariffs impose an additional 25% ad valorem rate of duty on all imports from Canada and Mexico (other than imports of Canadian energy resources, which are subject to a 10% ad valorem rate of duty) and an additional 10% ad valorem rate of duty on all imports from China. On March 4, 2025, the previously announced 25% tariff on Canadian and Mexican goods took effect and the tariff on Chinese goods was doubled to 20%. On June 4, 2025 tariffs on steel and aluminum increased from 25% to 50% on all steel and aluminum coming from Canada. Further, on July 31, 2025, President Trump issued an executive order increasing the ad valorem rate on imports from Canada to 35%. President Trump also has threatened a 30% ad valorem rate on imports from Mexico, though those are not currently in effect.

On April 2, 2025, President Trump introduced a baseline reciprocal tariff rate of 10% on most countries and individualized rates on some countries of up to 50%. On April 9, 2025, President Trump increased tariffs for Chinese goods to 125% (making the tariff rate for certain products up to 145% due to the “stacking” nature of the relevant tariffs), while also issuing an executive order that the reciprocal tariffs that had been announced on April 2, 2025 for other countries would be reduced to a baseline rate of 10% for a period of 90 days starting on April 10, 2025. On July 7, 2025, President Trump extended the initial 90-day pause on the reciprocal tariffs (except for those relating to China) and maintained the 10% baseline rate until August 1, 2025. On July 31, 2025, President Trump announced via an executive order reciprocal tariffs above the 10% baseline rate for a number of countries; these rates became effective as of August 7, 2025. In November 2025, the Supreme Court heard arguments in a case challenging tariffs imposed under the IEEPA. In February 2026, the Supreme Court issued a ruling that IEEPA does not authorize the imposition of tariffs. Although the ruling has been issued, its implications for trade policy and related administrative actions remain uncertain. The Company is reviewing the decision and will evaluate its potential impact, including with respect to any potential refunds, as further information becomes available.

We are continuing to evaluate the potential impact of the imposition of the announced tariffs, the effect of the Supreme Court decision on tariffs described above, and any additional or retaliatory tariffs, to our business and financial condition. While we do not believe that the tariffs announced by the U.S. in 2025 and through the date of filing this Form 10-K in 2026 will have a material adverse effect upon our results of operations, financial condition, or liquidity, the actual impact of new tariffs is subject to a number of factors, including the effective date and duration of such tariffs, changes in the amount, scope and nature of the tariffs in the future, any countermeasures that the target countries may take and any mitigating actions that may become available.

Foreign Currency Translation

For non-U.S. subsidiaries that operate in a local currency environment, assets and liabilities are translated into U.S. dollars at period-end exchange rates. Income, expense and cash flow items are translated at average exchange rates prevailing during the period. For non-U.S. subsidiaries that operate in a U.S. dollar functional currency, local currency inventories and property, plant and equipment are translated into U.S. dollars at rates prevailing when acquired, and all other assets and liabilities are translated at period-end exchange rates. Income and expense items are translated at average exchange rates prevailing during the period. Gains and losses which result from remeasurement are included in earnings.

Concentrations of Major Customers

Our customer base consists primarily of solar developers, independent power producers, utilities and EPCs. We do not require collateral on our accounts receivable.

At December 31, 2025, our largest customer and five largest customers accounted for 13.4% and 29.8%, respectively, of total accounts receivable. At December 31, 2024, our largest and five largest customers constituted 9.0% and 31.0%, respectively, of total accounts receivable.

During the year ended December 31, 2025, our two largest customers accounted for approximately 13.7% and 12.2%, respectively, of total revenue. During the year ended December 31, 2024, our two largest customers accounted for approximately 15.6% and 11.9%, respectively, of total revenue. During the year ended December 31, 2023, our largest customer accounted for approximately 13.4% of total revenue.

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

Performance Measures

In managing our business and assessing financial performance, we supplement the information provided by the financial statements with other operating metrics. These operating metrics are utilized by our management to evaluate our business, measure our performance, identify trends affecting our business and formulate projections. The primary operating metric we use to evaluate our sales performance and to track market acceptance of our products is MWs shipped, and specifically the change in MWs shipped from period to period.

MWs are measured for each individual project and are calculated based on the respective projects’ expected MW output once installed and fully operational.

We also utilize metrics related to price and cost of goods sold per MW, including average selling price (“ASP”) and cost per watt (“CPW”). ASP is calculated by dividing total applicable revenues by total applicable MWs, whereas CPW is calculated by dividing total applicable costs of goods sold by total applicable MWs. These metrics enable us to evaluate trends in pricing, manufacturing cost and customer profitability.

Key Components of Our Results of Operations

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

Revenue

We generate revenue from the sale of solar tracking and fixed-tilt systems, foundation solutions, parts, software and services. Our customers include solar developers, independent power producers, utilities, and EPCs. 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 the tracker system, fixed-tilt system, foundation solution, and parts can vary from days to several months. Contracts can range in value from hundreds of thousands to tens of millions of dollars.

Our revenue is affected by changes in the volume and ASPs of solar tracking systems purchased by our customers. The quarterly volume and ASP of our systems is driven by the supply of, and demand for, our products, changes in project mix between module type and wattage, geographic mix of our customers, strength of competitors’ product offerings, commodity prices and availability of government incentives to the end-users of our products.

Our revenue growth is dependent on continued growth in the size and number of solar energy projects installed each year as well as our ability to grow or maintain market share in each geography in which we compete, expand our global footprint to new and evolving markets, grow our supply chain network and production capabilities to satisfy demand and continue to develop and introduce new and innovative products that integrate emerging technologies and meet the performance requirements of our customers.

A majority of our revenue is recognized over time as work progresses. For single performance obligations, we use an input measure, the cost-to-cost method, to determine progress. We review and update the contract related estimates on an ongoing basis and recognize adjustments for any project specific facts and circumstances that could impact the measurement of the extent of progress, such as the total costs to complete the contracts, under the cumulative catch-up method. Due to the relatively short duration of our outstanding performance obligations, and our ability to estimate the remaining costs to be incurred, which are substantially all material costs covered under our material supply agreements with our suppliers, we have not recorded any material catch-up adjustments for the periods presented that would have impacted revenues or EPS related to revisions in our measurement of remaining progress of our performance obligations.

Cost of Revenue and Gross Profit

Cost of product and service revenue consists primarily of product costs, including raw materials, purchased components, net of any incentives or rebates earned from our suppliers, salaries, wages and benefits of manufacturing personnel, freight, tariffs, customer support, product warranty, amortization of developed technology, and depreciation of manufacturing and testing equipment. Our product costs are affected by: (i) the underlying cost of raw materials, including steel and aluminum; (ii) component costs, including electric motors and gearboxes; (iii) technological innovation; and (iv) economies of scale and improvements in production

processes and automation. We may experience disruptions to our supply chain and increased material and freight costs. When possible, we modify our production schedules and processes to mitigate the impact of these disruptions and cost increases on our margins. We do not currently hedge against changes in the price of our raw materials.

Gross profit may vary from quarter to quarter and is primarily affected by our volume, ASPs, product costs, project mix, customer mix, geographical mix, commodity prices, logistics rates, warranty costs, and seasonality. Gross profit will also be impacted by tax incentives we can recognize, for example ICMS value added tax benefits in Brazil, which will discontinue in 2033.

Operating Expenses

General and administrative expense consists primarily of salaries, benefits, and equity-based compensation related to our executive, sales, R&D costs, finance, human resources, information technology, and legal personnel, as well as travel, facility costs, marketing, credit loss provision, and professional fees. We currently have a sales presence in the U.S. and across North America, Latin America, Europe, the Middle East, Asia and Australia, with the majority of our sales in the U.S. We intend to continue to expand our sales presence and marketing efforts to additional countries.

Contingent consideration consists of the changes in fair value of the tax receivable agreement (“TRA”) entered into with a former indirect stockholder, concurrent with the acquisition of Array Technologies Patent Holdings Co., LLC by Former Parent, as well as the Earnout Consideration associated with the APA Purchase Agreement. The TRA liability and Earnout Consideration were recorded and subsequent changes in the fair value are recognized in earnings. See Note 15 – Commitments and Contingencies for discussion and analysis of the TRA and Earnout Consideration.

Depreciation consists of costs associated with property, plant and equipment not used in manufacturing of our products. We expect that as we continue to grow both our revenue and our general and administrative personnel, we may require some additional property, plant and equipment to support this growth resulting in additional depreciation expense.

Amortization consists of the expense recognized over the expected period of use of our developed technology, computer software, customer relationships, contractual backlog, and the STI and APA trade name intangible assets. Amortization related to certain acquired intangible assets is recorded as Total cost of revenue under the caption “Amortization of developed technology.”

Non-Operating Expenses

Interest income consists of interest earned on our cash and cash equivalents balance.

Interest expense consists of interest and other charges paid in connection with our Senior Secured Credit Facility, the Convertible Notes, and other debt held by our operations outside of the U.S.

We are subject to U.S. federal, state and non-U.S. income taxes. As we expand into additional foreign markets, we may be subject to additional foreign tax.

Reportable Segments

We report our results of operations in two segments; the Array legacy operating segment (“Array Legacy Operations”) and the legacy STI operating segment (“STI Operations”). The segment amounts included in this Item 7. Management’s Discussion and Analysis are presented on a basis consistent with our internal

management reporting. Additional information on our reportable segments is contained in Note 21 – Segment and Geographic Information in the accompanying notes to the consolidated financial statements.

Year Ended December 31, 2025 Compared to Year Ended December 31, 2024

Revenue

Consolidated revenue for the year ended December 31, 2025 increased by $368.3 million, or 40%, compared to the year ended December 31, 2024, primarily driven by higher revenue from Array Legacy Operations of 62%, partially offset by a 16% decline in STI Operations revenue.

Revenue from Array Legacy Operations, inclusive of contributions from APA, increased by $408.8 million, or 62%, for the year ended December 31, 2025 compared to the year ended December 31, 2024, primarily driven by an increase of approximately 62% in volume.

Revenue from STI Operations decreased by $40.5 million, or 16%, for the year ended December 31, 2025 compared to the year ended December 31, 2024. The decrease was primarily driven by a decrease of approximately 20% in volume, partially offset by a 5% increase in ASP.

Cost of Revenue and Gross Profit

Consolidated cost of revenue increased by $367.5 million, or 59%, for the year ended December 31, 2025 compared to the year ended December 31, 2024, in line with higher volume.

Consolidated gross profit increased by $0.9 million, or 0.3%, for the year ended December 31, 2025 compared to the year ended December 31, 2024. Consolidated gross margin decreased to 23% for the year ended December 31, 2025, as compared to 33% during the same period in the prior year.

Array Legacy Operations gross profit, inclusive of contributions from APA, increased by $30.0 million, or 11%, for the year ended December 31, 2025 compared to the year ended December 31, 2024. Gross margin decreased to 28% from 41% for the years ended December 31, 2025 and 2024, respectively. The decrease in gross margin was driven by a 22% increase in CPW, attributable to 13% higher tariffs, 6% from reduction in 45x amortization, and 3% from inflationary cost pressures. In addition, gross margin during the year ended December 31, 2024, included a one-time benefit of $4.0 million related to a settlement with a supplier, which was recorded as a reduction to Cost of product and service revenue.

STI Operations gross profit decreased by $29.1 million, or 105%, for the year ended December 31, 2025 compared to the year ended December 31, 2024. Gross margin for STI Operations decreased to (1)% from 11% for the years ended December 31, 2025 and 2024, driven primarily by a 5% increase in ASP that was

more than offset by a 16% increase in CPW from a one-time inventory valuation charge of $29.5 million and a 3% increase in CPW from inflationary cost pressures.

Operating Expenses

Consolidated general and administrative expenses, inclusive of APA, increased by $38.0 million, or 24%, for the year ended December 31, 2025 compared to the year ended December 31, 2024. The increase was primarily due to a $17.7 million increase in total compensation costs during the year ended December 31, 2025, the absence of $3.0 million in favorable one-time variable compensation adjustments recorded during the year ended December 31, 2024, $16.9 million in acquisition-related expenses and deferred compensation, and a $0.4 million increase in other costs.

Change in the fair value of contingent consideration, inclusive of APA, resulted in a loss of $0.2 million for the year ended December 31, 2025, driven by a $0.4 million increase in the fair value of the TRA liability, partially offset by a $0.2 million decrease in the fair value of the Earnout Consideration.

Consolidated depreciation and amortization expense, inclusive of APA, for the year ended December 31, 2025 decreased $9.9 million, or 27%, primarily due to certain assets acquired becoming fully amortized or fully impaired at December 31, 2024, partially offset by $3.5 million of incremental depreciation and amortization related to fixed and intangible assets acquired in the APA Acquisition.

During the years ended December 31, 2025 and 2024, the Company identified certain indicators of impairment related to the STI Operations reporting unit, which resulted in an impairment of goodwill and long-lived assets of $102.6 million and $327.9 million, respectively.

Other (Expense) Income, Net

Other expense was $1.0 million for both years ended December 31, 2025 and 2024. Other expense primarily consists of miscellaneous income and expense items.

Interest Income

Consolidated interest income for the year ended December 31, 2025 decreased by $4.9 million, or 29%, as compared to the year ended December 31, 2024, primarily as a result of lower yields on our cash management program.

Foreign Currency (Gain) Loss

Consolidated foreign currency gain was $2.0 million during the year ended December 31, 2025, due to currency movements related to monetary assets and liabilities denominated in currencies other than the respective functional currencies of the transacting entities. Consolidated foreign currency loss was $4.5 million during the year ended December 31, 2024, due to certain monetary assets and liabilities denominated in currencies other than the Brazilian real, which weakened significantly during 2024.

Interest Expense

Consolidated interest expense for the year ended December 31, 2025 decreased by $7.5 million, or 22%, compared to the year ended December 31, 2024, primarily due to refinancing with lower interest debt and changes in interest rates on our variable rate obligations.

Income Tax Expense (Benefit)

Consolidated income tax expense for the year ended December 31, 2025 increased by $33.2 million, or 326%, compared to the year ended December 31, 2024, shifting from an income tax benefit of $10.2 million in 2024 to income tax expense of $23.0 million in 2025. The increase in tax expense was primarily due to a decrease in our pre-tax loss, as we recorded a pre-tax loss of $29.2 million in 2025, compared to a pre-tax loss of $250.6 million in 2024.

An impairment charge of $102.6 million in 2025 for goodwill was reversed for tax purposes resulting in positive taxable income. The impairment reversal resulted in additional tax expense of approximately $22.3 million. A $10.2 million valuation allowance related to the inventory valuation charge and debt restructuring charge was accrued for Brazil. The APA acquisition added new state tax filing requirements and increased the Company’s apportioned income in existing states. Other book-tax basis differences attributed to the increased tax expense as well.

Debt Obligations

Senior Secured Credit Facility

On October 14, 2020, the Company entered into a credit agreement (as amended, the “Credit Agreement”) governing the Company’s senior secured credit facility, consisting of: (i) a $575 million senior secured seven-year term loan facility (the “Term Loan Facility”); and (ii) a $200 million senior secured five-year revolving credit facility (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Senior Secured Credit Facility”). The Credit Agreement was amended on February 23, 2021, February 26, 2021, March 2, 2023, and May 1, 2025 (the “Fourth Amendment”). The Fourth Amendment, among other things: (y) refinanced the Revolving Credit Facility with new revolving commitments and loans thereunder, reducing the total commitments to $166 million and extending the maturity date to October 14, 2028; and (z) revised the Consolidated First Lien Secured Leverage Ratio as applicable under Section 7.09 (Financial Covenant) of the Credit Agreement from 7.10:1.00 to 5.50:1.00.

On February 18, 2026, Array Tech, Inc. (f/k/a Array Technologies, Inc.) (the “Borrower”), a New Mexico corporation and wholly-owned subsidiary of the Company, entered into that certain Amendment No. 5 to Credit Agreement (the “Fifth Amendment”), by and among the Borrower, the Company’s wholly-owned subsidiary ATI Investment Sub, Inc., as holdings (“Holdings”), Goldman Sachs Bank USA, as administrative agent and collateral agent (“Goldman Sachs”), and the Lenders (as defined in the Fifth Amendment), to the Credit Agreement. The Fifth Amendment: (i) increases the revolving credit facility commitments under the original Credit Agreement from $166,000,000 to $370,000,000; (ii) extends the maturity of the revolving credit facility from October 14, 2028 to February 18, 2031; (iii) removes the credit spread adjustment with respect to Term SOFR (as defined in the Credit Agreement); and (iv) expands the number of currencies under which the Borrower can request revolving credit loans and letters of credit.

For further discussion regarding our debt obligations see Note 10 – Debt, in the accompanying notes to the consolidated financial statements.

Surety Bonds

We are required to provide surety bonds to various parties as required for certain transactions initiated during the ordinary course of business to guarantee our performance in accordance with contractual or legal obligations. These off-balance sheet arrangements do not adversely impact our liquidity or capital resources. As of December 31, 2025, we posted surety bonds totaling approximately $215.5 million.

Cash Flows (in thousands)


	Year Ended December 31,
	2025		2024
Net cash provided by operating activities	$	101,785	$	153,980
Net cash used in investing activities	(187,888)		(9,572)
Net cash used in financing activities	(38,053)		(11,844)

Historically, we have financed our operations with the proceeds from operating cash flows, capital contributions and short and long-term borrowings. Our ability to generate positive cash flow from operations is dependent on the strength of our gross margins as well as our ability to quickly turn our working capital. Based on our past performance and current expectations, we believe that operating cash flows will be sufficient to meet our liquidity needs in the next 12 months and beyond.

As of December 31, 2025, our cash balance was $244.4 million, of which $32.3 million was held outside the U.S., and net working capital was $492.0 million. We had $137.9 million available to us under our $166.0 million Revolving Credit Facility.

As amended by the Fourth Amendment, the Revolving Credit Facility had total commitments of $166.0 million at December 31, 2025 and a maturity date of October 14, 2028.

On June 27, 2025, we completed a private placement of $345 million in aggregate principal amount of 2031 Convertible Notes, resulting in net proceeds of $334.6 million, after deducting initial purchasers’ discounts and offering expenses. The proceeds were used to repay in full our Term Loan Facility and to repurchase $100.0 million aggregate principal amount of the 2028 Convertible Notes. The repurchased 2028 Convertible Notes had a net carrying value of $98.5 million, inclusive of unamortized debt discount, resulting in a gain on extinguishment of debt of approximately $20.1 million.

In connection with the issuance of the 2031 Convertible Notes, we also entered into capped call transactions designed to reduce potential dilution to common stockholders upon conversion of the notes (the “2031 Capped Calls”). These instruments cover approximately 42.5 million shares of common stock, with an initial strike price of $8.12 and a cap price of $12.74 per share, subject to anti-dilution adjustments. These instruments are scheduled to expire on July 1, 2031. The net effect of the 2031 Capped Calls is to raise the conversion price on the 2031 Convertible Notes from $8.12 to $12.74. However, these transactions are separate from the 2031 Convertible Notes and do not affect the terms of the notes or the rights of note holders.

We continually monitor and review our liquidity position and funding needs. Management believes that our ability to generate operating cash flows in the future and available borrowing capacity under our Senior Secured Credit Facility will be sufficient to meet our future short-term liquidity needs.

Operating Activities

For the year ended December 31, 2025, cash provided by operating activities was $101.8 million attributable to cash generated from earnings of $156.8 million, partially offset by a net cash outflow of $55.0 million from changes in our operating assets and liabilities.

Investing Activities

For the year ended December 31, 2025, cash used in investing activities was $187.9 million, of which $164.9 million related to cash consideration transferred to acquire APA, net of cash obtained in the acquisition, $22.0 million related to purchases of property, plant and equipment, and $1.0 million related to an additional equity investment.

Financing Activities

For the year ended December 31, 2025, net cash used in financing activities was $38.1 million. This was primarily driven by a $233.9 million repayment on our Term Loan Facility, $174.4 million repayment of other debt, $78.4 million repurchase of 2028 Convertible Notes, and $35.1 million premium paid in connection with the purchase of the 2031 Capped Calls, partially offset by an increase of $334.6 million and $151.1 million from net proceeds from the issuance of 2031 Convertible Notes and proceeds from the issuance of other debt, respectively, after deducting initial purchasers’ discounts and offering expenses.

APA Acquisition Earnout Consideration and Deferred Consideration

As discussed in Note 3 – Acquisition in the accompanying notes to the consolidated financial statements, the Purchase Agreement includes provisions providing for the Earnout Consideration and the payment of the Deferred Consideration of approximately $40.0 million. Each of the Deferred Consideration and the Earnout Consideration are described in more detail below.

Earnout Consideration

The Purchase Agreement includes an earnout provision pursuant to which Seller may be granted shares of the Company’s common stock, or equivalent cash value at the Buyer’s discretion, based upon APA’s achievement of certain financial performance targets during the three-year period ending September 30, 2028. The maximum number of shares payable as Earnout Consideration is 4,686,530 shares of common stock, which was determined by dividing $40 million by the volume weighted average price of the Company’s common stock for the 10 trading days immediately following the Closing Date. The number of shares payable will be subject to reduction if the cumulative value of the Earnout Consideration earned (measured on each date such shares are issued) exceeds $90 million. The Purchase Agreement provides that, to the extent the issuance of any Earnout Consideration or Deferred Consideration Shares would require stockholder approval under Nasdaq Listing Rule 5635(a), the Company will pay cash in lieu of issuing such shares, unless such stockholder approval has been obtained. The principal Seller continues to assume the managerial responsibilities of APA. For a discussion of the accounting of the Earnout Consideration, see “–Business Combinations” below.

Deferred Consideration

The Deferred Consideration which will be payable to Seller in three installments (each, a “Deferred Consideration Installment”): (i) within five business days after the first anniversary of the Closing Date, an amount equal to 50% of the Deferred Consideration; (ii) on December 31, 2026, an amount equal to (A) 50% of the Deferred Consideration multiplied by (B) the proportion of the two-year period from the Closing Date to the second anniversary of the Closing Date that has elapsed as of December 31, 2026; and (iii) within five business days after the second anniversary of the Closing Date, an amount equal to the remaining balance of the Deferred Consideration. As more fully described in the Purchase Agreement, the Deferred Consideration Installments are subject to reduction if certain equity holders of Seller cease to be employees of the Company under certain circumstances. Each Deferred Consideration Installment will, at the Company’s election, be paid; (x) in cash; (y) through the issuance of shares of Company common stock, par value $0.001 per share, valued at the closing price on the trading day immediately preceding the applicable Deferred Consideration anniversary (if any such shares are issued, the “Deferred Consideration Shares”); or (z) by any combination of the foregoing. As the Deferred Consideration Installments are tied to future service to the Company, they are considered compensatory and not included in purchase consideration.

Critical Accounting Estimates

Our consolidated financial statements are prepared in accordance with U.S. GAAP. In connection with the preparation of our consolidated financial statements, we are required to make assumptions and estimates about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time our consolidated financial statements are prepared. On a regular basis, we review the accounting policies, assumptions, estimates and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with U.S. GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates. To the extent that there are material differences between these estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected.

We consider an accounting policy to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the consolidated financial statements.

Business Combinations

We completed one business combination for purchase consideration of $185.4 million during the year ended December 31, 2025. In accordance with Accounting Standards Codification (“ASC”) Topic 805 Business Combinations, total consideration was first allocated to the fair value of assets acquired and liabilities assumed, with the excess being recorded as Goodwill. We use our best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. Intangible assets have been recognized apart from goodwill whenever an acquired intangible asset arises from contractual or other legal rights, or whenever it is capable of being separated or divided from the acquired entity. Determining these fair values required us to make significant estimates and assumptions, particularly with respect to acquired intangible assets. The determination of fair value required considerable judgment and were sensitive to changes in underlying assumptions, estimates and market factors. The preliminary fair value of the identifiable intangible assets has been estimated using the Multi-Period Excess Earnings Method (Customer relationships and Backlog), Relief from Royalty Method (Trade name), and Replacement Cost Method

(Developed technology and Computer software and other). The significant fair value inputs used to estimate the fair value of the identifiable intangible assets include a discount rate and revenue and expense projections.

Earnout Consideration

As discussed, the Purchase Agreement includes a provision for the Earnout Consideration. The maximum number of shares payable as Earnout Consideration is 4,686,530 shares of common stock, which was determined by dividing $40 million by the volume weighted average price of the Company’s common stock for the 10 trading days immediately following the Closing Date. The number of shares payable will be subject to reduction if the cumulative value of the Earnout Consideration earned (measured on each date such shares are issued) exceeds $90 million. The Purchase Agreement provides that, to the extent the issuance of any Earnout Consideration or Deferred Consideration Shares would require stockholder approval under Nasdaq Listing Rule 5635(a), the Company will pay cash in lieu of issuing such shares, unless such stockholder approval has been obtained.

The Earnout Consideration is accounted for as contingent consideration, and the fair value is estimated each reporting period. As of December 31, 2025, the Earnout Consideration was estimated to have a fair value of $22.4 million using a Monte-Carlo simulation method. Changes in fair value of the contingent liability are recognized in Changes in fair value of contingent consideration in the accompanying consolidated statements of operations. Estimating the amount of payments that may be made under the Earnout Consideration is by nature imprecise. The significant fair value inputs used to estimate the future expected Earnout Consideration payments to Seller include a discount rate, earnings forecasts, and actual and estimated future volatility in the Company’s stock price.

Goodwill

Our goodwill represents the excess of the purchase price of business combinations over the fair value of the net assets acquired. Goodwill impairment testing requires significant judgment and management estimates, including, but not limited to, the determination of: (i) the number of reporting units; (ii) the goodwill and other assets and liabilities to be allocated to the reporting units; and (iii) the fair values of the reporting units. The estimates and assumptions described above, along with other factors such as discount rates, will significantly affect the outcome of the impairment tests and the amounts of any resulting impairment losses. We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment on an annual basis during the fourth quarter of each year, and between annual tests whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If we use a qualitative approach and determine that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we would then perform the first step of the goodwill impairment test, which would consist primarily of a discounted cash flow (“DCF”) analysis using the income approach, with the resulting value compared to the Guideline Public Company method (“GPC”) marketplace EBITDA multiples to corroborate the fair value of the reporting unit.

During the fourth quarter of 2025, the Company updated the long-term projections for its reporting units as part of its annual goodwill impairment testing process. These projections reflect local market conditions, expected market share, strategic changes, and other key assumptions. For STI Operations, the updated projections incorporated the Company’s fourth-quarter 2025 decision to phase out a version of the H250 product that was not compatible with SmarTrack® and to focus instead on the SmarTrack®-compatible version introduced in 2024. The projections also reflected management’s intent to begin selling and distributing the Company’s flagship tracker, DuraTrack®, through STI in the future. These changes, together with local market conditions experienced during the fourth quarter of 2025, significantly reduced projected cash flows and indicated potential impairment related to the Company’s STI Operations reporting unit as of December 31, 2025. Although the Company did not identify indicators of impairment related to the Company’s Array Legacy Operations reporting unit as of December 31, 2025, Management, with the assistance of a third-party valuation specialist, elected to perform quantitative goodwill impairment tests of both the Array Legacy Operations and STI Operations reporting units as of December 31, 2025.

During the quarters ended September 30, 2024 and December 31, 2024, the Company experienced a sustained decline in its stock price, which hit a 52-week low during the third quarter of 2024 and again during the fourth quarter of 2024, resulting in a decrease in market capitalization. In addition, the Company updated its long-term projections for the Company’s reporting units as of September 30, 2024 and December 31, 2024 and evaluated the execution risk associated with the Company’s projections and market conditions. As a result, the Company identified indicators of impairment related to the Company’s reporting units during the third and fourth quarters of 2024. Management, with the assistance of a third-party valuation specialist, performed quantitative goodwill impairment tests of the Array Legacy Operations and STI Operations reporting units as of September 30, 2024 and December 31, 2024.

The estimated fair value of the Array Legacy Operations reporting unit was significantly higher than the carrying balance of the reporting unit as of each of the testing dates. The fair value of the Array Legacy Operations and STI Operations reporting units were determined using the income approach and then compared to the GPC marketplace EBITDA multiples to corroborate the fair value of the reporting unit. As a result of these tests, the Company recorded impairments to goodwill totaling $102.6 million and $236.0 million during years ended December 31, 2025 and 2024, respectively, related to STI Operations reporting unit. Subsequent to recording the impairment of goodwill, the Company reconciled the overall market capitalization of the Company, within a reasonable range, to the sum of the estimated fair values of both of the Company’s reporting units.

The significant assumptions used in determining the fair value of the Company’s reporting units primarily relate to the revenue growth rate, the forecasted EBITDA margin, and the selected discount rate used in the discounted cash flow model under the income approach. Under the GPC method, the selection of EBITDA multiples to be used requires significant judgment.

The most significant assumption used in determining the estimated fair value of STI Operations is the discount rate assumption. Refer also to Note 7 - Goodwill, Long-Lived Assets, and Other Intangible Assets for further information.

Long-Lived Assets

When events, circumstances or operating results indicate that the carrying values of long-lived assets, including our finite lived intangible assets, might not be recoverable through future operations, the Company prepares projections of the undiscounted future cash flows expected to be generated from the underlying asset group and the cash flows resulting from the asset groupings eventual disposition. If the projections indicate that the underlying asset grouping is not expected to be recoverable, the estimated fair value of the asset group is determined. An impairment loss is recognized based on the difference between the carrying value of the asset

group and its estimated fair value. The loss is allocated to the long-lived assets of the group on a pro-rata basis using the relative carrying amounts of those assets. The Company identified indicators of impairment during the years ended December 31, 2025 and 2024 associated with the STI Operations asset groups, and as a result, performed an undiscounted cash flow tests on the same dates that the reporting unit goodwill was tested for impairment. The sum of the undiscounted cash flows exceeded the carrying balances for each of the STI Operations asset groups as of December 31, 2025. However, the sum of the undiscounted cash flows was less than the carrying balance for one of the STI Operations asset groups as of December 31, 2024.

As a result, with the assistance of a third-party valuation specialist, management estimated the fair value of the asset group as of December 31, 2024, and recorded an impairment loss of $91.9 million, which was allocated to the long-lived assets of the group on a pro rata basis on the difference between the estimated fair value of the asset group and its carrying value. In determining the fair value of the asset group, the Company used a DCF analysis using the income approach with the resulting value compared to GPC marketplace EBITDA multiples to corroborate the fair value of the reporting unit. The significant assumptions used in determining the fair value of the asset group are similar to the significant assumptions used in determining the fair value the Company’s reporting units. Refer to Note 7 - Goodwill, Long-Lived Assets, and Other Intangible Assets for further information.

Equity-Based Compensation

We granted restricted stock units (“RSUs”) to employees and Performance Stock Units (“PSUs”) to certain executives. The PSUs contain performance and market conditions. The PSU grants were valued using the Monte Carlo simulation method and the assigned fair value on grant date will be recognized on a straight-line basis over the vesting term of the awards. The probability of the awards meeting the performance related vested conditions is not included in the grant date fair value, but rather will be estimated quarterly and we will true-up the expense recognition accordingly upon any probability to vest revision. We account for forfeitures as they occur.

Recent Accounting Pronouncements

Refer to Note 2 – Summary of Significant Accounting Policies in the accompanying notes to our consolidated financial statements included in this Annual Report on Form 10-K for a discussion of recent accounting pronouncements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

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 fluctuations in steel and aluminum prices and customer concentrations. We do not hold or issue financial instruments for trading purposes.

Concentrations of Major Customers

Our customer base consists primarily of solar developers, independent power producers, utilities and EPCs. We do not require collateral on our accounts receivable.

Commodity Price Risk

We are subject to risk from fluctuating market prices of certain commodity raw materials, including steel and aluminum, that are used in our products. Prices of these raw materials may be affected by supply restrictions, regulations, fuel prices, energy costs, labor shortages, labor disputes, freight transportation delays or availability, disruption logistics, political unrest, industry, general U.S. and global economic conditions, or other unforeseen circumstances from time to time, and we do not enter into hedging arrangements to mitigate commodity risk. Significant price changes for these raw materials could reduce our operating margins if we are unable to recover such increases from our customers, and could harm our business, financial condition and results of operations.

Interest Rate Risk

As of December 31, 2025, our long-term debt, net of discounts and issuance costs, was $658.7 million, of which $12.8 million is subject to variable-rate interest agreements and is therefore subject to future changes in interest rates. Accordingly, a 50 basis point change in interest rates would impact our expected annual interest expense for the next 12 months by approximately $0.1 million.

Customer Financing Exposure

We are also indirectly exposed to interest rate risk because many of our customers depend on debt financing to purchase our product. An increase in interest rates could make it challenging for our customers to obtain the capital necessary to make such purchases on favorable terms, or at all. Such factors could reduce demand or lower the price we can charge for our product, thereby reducing our net sales and gross profit.

Foreign Currency Exchange Risk

We do business in various foreign countries where the functional currency used to transact differs from our reporting currency. As a result, we are subject to the risk of foreign currency exchange rate fluctuations.

Item 8. Financial Statements and Supplementary Data

The financial statements and supplementary data required by this item are included after the Signature page of this Annual Report on Form 10-K beginning on page F-1.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is: (i) recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms; and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2025. Based upon the evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

Management’s Report on Internal Control Over Financial Reporting.

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in the Exchange Act Rules 13a-15(f) and 15d-15(f). The Company’s management, including the Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the results of this evaluation, the Company’s management concluded that internal control over financial reporting was effective as of December 31, 2025. Our independent registered public accounting firm, Deloitte & Touche LLP, has audited the effectiveness of our internal control over financial reporting as of December 31, 2025, as stated in their report, which appears herein.

As previously disclosed in our annual report on Form 10-K for the year ended December 31, 2023, we identified material weaknesses in our internal control over financial reporting. Management implemented remediation measures during 2024, and as disclosed in our annual report on Form 10-K for the year ended December 31, 2024, concluded that these material weaknesses were remediated as of December 31, 2024. There were no material weaknesses in internal control over financial reporting as of December 31, 2025.

We completed the APA Acquisition during the quarter ended September 30, 2025, and are in the process of integrating their operations and internal controls, which we expect to finish within one year of acquisition. In accordance with SEC guidance, our December 31, 2025 assessment of internal controls excludes the internal control activities of APA, which represented approximately 9% of total consolidated assets of the Company at December 31, 2025, excluding goodwill and intangible assets, which are included within the scope of management’s assessment, and represented approximately 4% of total consolidated revenues of the Company for the year ended December 31, 2025.

Changes in Internal Control over Financial Reporting

During the year ended December 31, 2025, there have been no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 9B. Other Information

Trading Plans

From time to time, our directors and executive officers may adopt plans for the purchase or sale of our securities. Such plans may be designed to satisfy the affirmative defense conditions of Rule 10b5-1 under the Exchange Act or may constitute non-Rule 10b5-1 trading arrangements (as defined in Item 408(c) of Regulation S-K). During the three months ended December 31, 2025, none of our directors or executive officers adopted, amended or terminated any such plan or trading arrangement.

None.

PART III

Item 10. Directors, Executive Officers and Corporate Governance

The information required by this item and not set forth below will be contained in our definitive proxy statement to be filed with the SEC within 120 days after December 31, 2025 pursuant to Regulation 14A under the Exchange Act in connection with our 2026 Annual Meeting of Stockholders, or the “Proxy Statement,” and is incorporated herein by reference.

Item 405 of Regulation S-K calls for disclosure of any known late filing or failure by an insider to file a report required by Section 16(a) of the Exchange Act. To the extent disclosure for delinquent reports is being made, it can be found under the caption “Delinquent Section 16(a) Reports” in our Proxy Statement and, in accordance with General Instruction G to Form 10-K, is hereby incorporated herein by reference.

Insider Trading Policy

We have adopted an Insider Trading Policy governing the purchase, sale and/or other dispositions of our securities by the Company, our directors, officers and employees of the Company and its subsidiaries. A copy of this policy is filed as an exhibit to this Annual Report on Form 10-K. Generally, our insider trading policy prohibits our directors, officers and employees from holding our common stock in a margin account or entering into hedging transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds, because such transactions may permit a director, officer or employee to continue to own securities obtained through our employee benefit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, the individual may no longer have the same objectives as our other stockholders.

Code of Conduct

We have adopted a written Code of Business Conduct that applies to all officers, directors and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The Code of Business Conduct is available on our website at www.arraytechinc.com. If we make any substantive amendments to the Code of Business Conduct or grant any waiver from a provision of the Code of Business Conduct to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website or in a Current Report on Form 8-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Array Technologies, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Array Technologies, Inc. (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), changes in redeemable perpetual preferred stock and stockholders’ equity (deficit), and cash flows, for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2026, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to an account or disclosure that is material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

F-2

Goodwill – STI Operations– Refer to Note 2 and 7 to the financial statements

Critical Audit Matter Description

The Company’s goodwill for its STI Operations reporting unit (“STI”) is tested annually for impairment during the fourth quarter of each year, and more frequently if events and circumstances indicate that the assets might be impaired. The Company’s evaluation of STI’s goodwill for impairment involves the comparison of the fair value of the reporting unit to its carrying value. The Company used a quantitative approach for goodwill to determine the fair value of STI based upon the discounted cash flow method, which was compared to an indication of value using the guideline publicly traded companies method. The fair value determination using the discounted cash flow method requires management to make significant estimates and assumptions related to forecasts of future revenue growth rates, earnings before interest, taxes, depreciation, and amortization (“EBITDA”) margins, and the discount rate. The comparison of the fair value of the reporting unit to the marketplace multiples determined under the guideline publicly traded companies method requires management to make assumptions related to the selection EBITDA multiples. As of the December 31, 2025 testing date, the carrying value of STI exceeded its estimated fair value, and as a result, the Company recorded an impairment totaling $102.6 million during the year ended December 31, 2025.

Given the significant judgments made by management to estimate the fair value of STI, performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to forecasts of future revenue growth rates, and EBITDA margins, as well as the selection of the discount rate and the comparison of the fair value to marketplace multiples, required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the forecasts of future revenue growth rates and EBITDA margins ("forecasts"), the selection of the discount rate and the comparison of the marketplace multiples for STI included the following, among others:

•We tested the effectiveness of controls over management's determination of the estimated fair value of STI, such as controls related to management's forecasts and the selection of the discount rate, and market multiples used.

•We evaluated the reasonableness of management's forecasts by comparing the forecasts to (1) historical results, (2) internal communications, (3) inquiry with non-accounting personnel and (4) forecasted information included in industry reports that STI operates within.

•With the assistance of our fair value specialists, we evaluated (1) the valuation methodologies used, (2) the marketplace multiples used by management to compare to the discounted cash flow fair value, and (3) the discount rate used in determining the present value of the expected cash flows by developing independent estimates and comparing those to the rate selected by management.

•We considered the impact of (1) changes in the industry and (2) current macroeconomic factors on management's forecasts by analyzing key inputs of the forecast and evaluating the reasonableness and trends of the key inputs as a comparison to changes in the industry and current macroeconomic factors.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Array Technologies, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Array Technologies, Inc. (the "Company") as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 25, 2026, expressed an unqualified opinion on those financial statements.

As described in Management's Report on Internal Control Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at APA Solar, LLC, which was acquired on August 14, 2025, and whose financial statements represented approximately 9% of total consolidated assets, excluding goodwill and intangible assets, which are included within the scope of management's assessment, and represented approximately 4% of total consolidated revenues of the Company as of and for the year ended December 31, 2025. Accordingly, our audit did not include the internal control over financial reporting at APA Solar, LLC.

Basis for Opinion

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

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

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and

F-5

procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

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

Notes to Consolidated Financial Statements

1. Organization and Business

Array Technologies, Inc. (the “Company”), formerly ATI Intermediate Holdings, LLC, is a Delaware corporation formed in December 2018 as a wholly owned subsidiary of ATI Investment Parent, LLC (“Former Parent”). On October 14, 2020, the Company converted from a Delaware limited liability company to a Delaware corporation and changed the Company’s name to Array Technologies, Inc.

On January 11, 2022, the Company acquired 100% of the share capital of Soluciones Técnicas Integrales Norland, S.L.U., a Spanish private limited liability Company, and its subsidiaries (collectively, “STI”) with cash and common stock of the Company (the “STI Acquisition”). The STI Acquisition was accounted for as a business combination.

Upon completion of the STI Acquisition, the Company began operating as two reportable operating segments: the Array Legacy operating segment (“Array Legacy Operations”) and the newly acquired operating segment (“STI Operations”) pertaining to STI.

On August 14, 2025, the Company acquired 100% of the issued and outstanding equity interests of APA Solar, LLC (“APA”), the terms of which are discussed in Note 3 – Acquisition (the “APA Acquisition”). APA designs, engineers and manufactures solar racking, mounting and foundation systems, and the integration of such systems into the Company’s business model through the APA Acquisition supports the Company’s strategic expansion in the solar energy market and expands its operational footprint. APA is currently reported within the Array Legacy Operations segment.

Headquartered in Albuquerque, New Mexico, the Company is a leading global provider of solar tracking technology to utility-scale and distributed generation customers, who construct, develop and operate solar PV sites.

2. Summary of Significant Accounting Policies

Basis of Accounting and Presentation

The accompanying consolidated financial statements were prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

Principles of Consolidation

The consolidated financial statements include the accounts of Array Technologies, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated upon consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Although management believes its estimates are reasonable, actual results could differ from those estimates.

Array Technologies, Inc.

Notes to Consolidated Financial Statements

Business Combinations

The Company accounts for its business acquisitions under the acquisition method of accounting in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 805 Business Combinations (“ASC 805”). The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, asset lives, and market multiples, amongst other items.

Foreign Currency Translation

The Company’s foreign subsidiaries have functional currencies that are different than our reporting currency. When translating balances from the functional currency to the reporting currency, assets and liabilities are translated into U.S. dollars at period-end exchange rates, retained earnings is translated at historical rates, and income, expenses, and cash flow items are translated at average exchange rates prevailing during the period. Translation adjustments for these subsidiaries are accumulated within accumulated other comprehensive income. In situations when a foreign subsidiary has a local currency that is different than the functional currency, monetary assets and liabilities are translated into the functional currency at the period-end exchange rates, and non-monetary assets and the related income statement effects are translated into the functional currency using historical rates. Gains and losses that result from remeasurement from a local currency to the functional currency are included in earnings.

Cash and Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. We regularly maintain cash balances that exceed insured amounts, but we have experienced no losses associated with these amounts to date. At December 31, 2025 and 2024, restricted cash represents cash deposited with a financial institution by one of our foreign subsidiaries that was restricted for the issuance of certain surety bonds.

Accounts Receivable

The Company’s accounts receivable are due primarily from customers across the U.S. and internationally. Credit is extended in the normal course of business based on evaluation of a customer’s financial condition and, generally, collateral is not required. Trade receivables consist of uncollateralized customer obligations due under normal trade terms requiring payment within 30 to 60 days of the invoice date. Management regularly reviews outstanding accounts receivable and provides for estimated credit losses through an estimate of expected credit losses valuation account.

The allowance for credit losses is a valuation account that is deducted from a financial asset’s amortized cost to present the net amount we expect to collect from the asset. We estimate allowances for credit losses using relevant available information from both internal and external sources. We monitor the estimated credit losses associated with our trade accounts receivable and unbilled accounts receivable based primarily on our collection history and the delinquency status of amounts owed to us, which we determine based on the aging of such receivables. In evaluating the level of established reserves, management makes judgments regarding the customers’ ability to make required payments, economic events, and other factors. As the financial conditions of these customers change, circumstances develop, or additional information becomes available,

F-17

Table of Contents

Array Technologies, Inc.

Notes to Consolidated Financial Statements

adjustments to the valuation account may be required. When deemed uncollectible, the receivable is charged against the valuation account for credit losses or directly written off.

Unbilled receivables represent temporary timing differences between shipments made and billing milestones achieved and are recorded in the accounts receivable balances. Such amounts have not been billed due to pending commercial criteria, such as billing on a specified date of the month or upon completion of mega-watt deliveries. Unbilled receivables are invoiced once the underlying commercial criteria have been met and we expect payment within 30 to 60 days.

Inventories

Inventories consist of raw materials and finished goods and are stated at the lower of cost or estimated net realizable value using costing methods that approximate first-in, first-out (“FIFO”). Provisions are made to reduce excess or obsolete inventories to their estimated net realizable values.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, net of accumulated depreciation and amortization. Improvements, betterments and replacements which extend the life of an asset are capitalized. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the respective assets. Repair and maintenance costs are expensed as incurred.

A gain or loss on the sale of property, plant and equipment is calculated as the difference between the cost of the asset disposed of, net of depreciation, and net sales proceeds received. A gain or loss on an asset disposal is recognized in the period that the sale occurs.

Equity Investment

On November 6, 2024, Array invested $3.0 million through a Simple Agreement of Future Equity (“SAFE”) with a technology company. On June 2, 2025, the SAFE investment converted into 182,669 preferred shares of the technology company at the predetermined price. The conversion did not result in the recognition of a gain or loss.

In the fourth quarter of 2025, the same technology company achieved certain defined milestones, upon which Array invested an additional $1.0 million in accordance with the terms and conditions of the original SAFE. In the first quarter of 2026, the Company expects to execute an additional SAFE governing the terms and conditions of the incremental investment.

Array’s initial investment of $3.0 million is recorded as an equity investment at cost and is included within Other assets in the consolidated balance sheet. The investment will be carried at cost and remeasured to fair value if impaired or if there are observable transaction prices. The additional investment of $1.0 million is recorded at cost and is included within Prepaid expenses and other on the consolidate balance sheet.

Array may invest up to $1.0 million in additional future SAFEs, contingent upon the technology company’s achievement of defined milestones. As of December 31, 2025, no additional commitments have been recognized, and no impairment indicators have been identified.

Notes to Consolidated Financial Statements

Leases

The Company determines if an arrangement contains a lease at inception by determining if it conveys the right to control the use of an identified asset in exchange for consideration. At the same time, the Company also assesses whether the lease should be classified as an operating lease or a finance lease, depending on the specific terms of each lease.

Lease right-of-use assets (“ROU assets”) and associated lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. ROU assets represent the Company’s right to use an underlying asset during the lease term, and lease liabilities represent the Company’s obligation to make lease payments. Certain lease agreements may include one or more options to extend or terminate a lease if it is reasonably certain that the Company will exercise such options.

ROU assets also include any initial direct costs and prepayments less lease incentives. Because most of the Company’s leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. Lease expense is recognized on a straight-line basis over the lease term.

ROU assets and the corresponding lease liabilities are included in Lease assets, Current portion of lease liabilities, and Lease liabilities, net of current portion in our consolidated balance sheets.

Long-Lived Assets

In testing long-lived assets and goodwill for impairment, the Company first tests its long-lived assets for impairment, and then tests the goodwill of a reporting unit that includes the long-lived assets covered under the long-lived asset test for impairment. If an asset group includes only a portion of a reporting unit, the carrying amount of goodwill is not included in the asset group. The carrying values are adjusted, if necessary, for the result of each impairment test prior to performing the next test.

When events, circumstances or operating results indicate that the carrying values of long-lived assets might not be recoverable through future operations, the Company prepares projections of the undiscounted future cash flows expected to be generated from the underlying asset group and the cash flows resulting from the asset groupings eventual disposition. If the projections indicate that the underlying asset grouping is not expected to be recoverable, the estimated fair value of the asset group is determined. An impairment loss is recognized based on the difference between the carrying value of the asset group and its estimated fair value. The loss is allocated to the long-lived assets of the group on pro-rata basis using the relative carrying amounts of the asset groups long-lived assets.

During the years ended December 31, 2025 and 2024, the Company identified certain indicators of impairment related to its long-lived assets, and as a result, tested certain asset groups for impairment, which resulted in an impairment of long-lived assets of $91.9 million during 2024. See Note 7 – Goodwill, Long-Lived Assets, and Other Intangible Assets for additional information.

There was no impairment of long-lived assets for the year ended December 31, 2025 and 2023.

Notes to Consolidated Financial Statements

Goodwill and Indefinite-Lived Intangible Asset

Goodwill represents the excess of the consideration transferred over the estimated fair value of assets acquired and liabilities assumed in a business combination. Intangible assets are measured at their respective fair values as of the acquisition date and may be subject to adjustment within the measurement period, which may be up to one year from the acquisition date. The Company does not amortize goodwill but instead tests goodwill for impairment annually, or more frequently if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. Such triggering events potentially warranting an annual or interim goodwill impairment assessment include, among other factors, declines in historical or projected revenue, operating income or cash flows, and sustained decreases in the Company’s stock price or market capitalization.

Goodwill is assessed for impairment using either a qualitative assessment or quantitative approach to determine whether it is more likely than not that the fair value of the reporting unit is less than the carrying amount. The qualitative assessment evaluates factors including macroeconomic conditions, industry-specific and company-specific considerations, legal and regulatory environments, and historical performance. If the Company cannot determine if it is more likely than not that the fair value of a reporting unit is greater than its carrying value, a quantitative assessment is performed. The quantitative approach compares the estimated fair value of the reporting unit to its carrying amount, including goodwill. Impairment is indicated if the estimated fair value or the reporting unit is less than the carrying amount of the reporting unit, and an impairment charge is recognized for the differential.

When determining the fair value of a reporting unit using the quantitative approach, we determine the fair value of the reporting unit using an income approach based on discounted cash flows. The fair value determined under the income approach is then compared to guideline publicly-traded companies (“GPC”) market place EBITDA multiples to corroborate the fair value of the reporting unit determined under the income approach.

During the years ended December 31, 2025 and 2024, the Company identified certain indicators of impairment on various dates, and as a result, performed goodwill impairment tests, which resulted in impairments of goodwill totaling $102.6 million and $236.0 million, respectively. See Note 7 – Goodwill, Long-Lived Assets, and Other Intangible Assets for additional information. There was no impairment of goodwill for the years ended December 31, 2023.

The Company has one indefinite-lived intangible asset for a Trade name it acquired as part of a past acquisition associated with the Array Legacy Operations reporting unit. The Company performs an annual impairment test on its Trade name indefinite-lived intangible asset, utilizing a qualitative or quantitative impairment analysis during the fourth quarter of each year. There were no indicators of impairment associated with this Trade name.

Divestiture of Investment in Equity Securities

In June 2024, we divested 100% of our equity investment in preferred stock of a private company we purchased in 2021. We received $12.0 million in proceeds for the divestiture in July 2024. No gain or loss resulted from this transaction.

Amortizable and Other Intangible Assets

over the assets’ estimated useful lives. The basis of amortization approximates the pattern in which the assets are utilized, over their estimated useful lives.

Debt Discount and Issuance Costs

Debt discount and issuance costs incurred to issue debt are deferred and amortized using the effective interest method as a component of interest expense over the life of the related debt agreement. Amortization expense of debt discount and deferred issuance costs was $5.2 million, $6.1 million and $10.6 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Revenue Recognition

In accordance with ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”), the Company recognizes revenues from the sale of solar tracking systems, parts, installation services, extended warranties on solar tracker system components and software licenses. The Company determines its revenue recognition through the following steps: (i) identification of the contract or contracts with a customer; (ii) identification of the performance obligations within the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations within the contract; and (v) recognition of revenue when, or as the performance obligation has been satisfied.

In assessing the recognition of revenue, the Company also evaluates whether two or more contracts should be combined and accounted for as one contract and if the combined or single contract should be accounted for as multiple performance obligations which could change the amount of revenue and profit (loss) recorded in a period. Further, the Company assesses whether control of the product or services promised under the contract is transferred to the customer at a point in time or over time.

Performance Obligations

The Company’s contracts for specific solar tracker system projects with customers are predominantly accounted for as a single performance obligation, because the Company is integrating the solar tracking system components and related services as part of a single project. The Company’s performance creates and enhances an asset that the customer controls as the Company performs under the contract, which is principally as tracker system components are delivered to the designated project site. The Company sources the component parts from third party manufacturers, it obtains control and receives title of such parts before transferring them to the customer because the Company is responsible for fulfillment to its customer. The Company’s engineering services and professional services are interdependent with the component parts whereby the parts form an input into a combined output for which it is the principal, and the Company could redirect the parts before they are transferred to the customer if needed. The customer owns the work-in-process over the course of the project and the Company’s performance enhances a customer-controlled asset, resulting in the recognition of the performance obligation over time.

In contracts with a single performance obligation, the Company’s obligation is satisfied over-time as control is transferred to the customer by measuring the progress toward complete satisfaction of the performance obligation using an input (i.e., the “cost-to-cost”) method. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The costs of materials and hardware components are recognized as incurred, which is typically upon delivery to the customer site or upon transfer of control while in transit.

F-21

Array Technologies, Inc.

Notes to Consolidated Financial Statements

For contracts with customers that result in multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. These contracts include contracts for the sale of components, contracts with installation services, solar tracker systems sold with an extended warranty, and contracts that include the sale of software and maintenance. For all years presented, the transaction price associated with extended warranties and the sale of software and maintenance was not material. The Company generally uses the expected cost-plus margin approach to estimate the standalone selling price of each performance obligation.

For contracts related to the sale of components as opposed to contracts to provide an integrated solar tracker project, the Company’s obligation to the customer is to deliver components that are used by the customer to create a tracker system and does not include engineering or other professional services or the obligation to provide such services in the future. Under these arrangements, each component is a distinct performance obligation, and often the components are delivered in batches at different points in time. The Company estimates the standalone selling price (“SSP”) of each component performance obligation based on a cost-plus margin approach. Revenue allocated to a component is recognized at the point in time that control of the component transfers to the customer, which is usually upon delivery to the customer’s site.

Contracts are often modified through change orders to account for changes in specifications or design, manner of performance, equipment, materials, scope of work, and/or the period of completion of the project. Although the Company evaluates each change order to determine whether such modification creates a separate performance obligation, the majority of change orders are for goods or services that are not distinct within the context of the original contract and, therefore, not treated as separate performance obligations but rather as a modification of the existing contract and performance obligation.

Bill and Hold Arrangements

In certain situations, the Company recognizes revenue under bill-and-hold arrangements with its customers. In all bill-and-hold arrangements, because the customers lack sufficient storage capacity to accept a large amount of material prior to the start of construction, they request that the Company keep the product in our custody. The material is bundled or palletized in the Company’s warehouses, identified separately as belonging to the respective customer and is ready for immediate transport to the customer project upon customer request. Additionally, title and risk of loss has passed to the customer and the Company does not have the ability to use the product or direct it to another customer.

Contract Estimates

A majority of our revenue is recognized over time as work progresses, and for a single performance obligation, we use an input measure, the cost-to-cost method, to determine progress. We review and update the contract related estimates on an ongoing basis and recognize adjustments for any project specific facts and circumstances that could impact the measurement of the extent of progress such as the total costs to complete the contracts, under the cumulative catch-up method. Due to the relatively short duration of our outstanding performance obligations, and our ability to estimate the remaining costs to be incurred, which are substantially all material costs covered under our material supply agreements with our suppliers, we have not recorded any material catch-up adjustments for the periods presented that would have impacted revenues or EPS related to revisions in our measurement of remaining progress of our performance obligations.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled accounts receivable for goods or services delivered but not invoiced, and deferred revenue (contract liabilities) in the consolidated balance sheets. The majority of the Company’s contract amounts are billed as work progresses in accordance with agreed-upon contractual terms, which generally coincide with the shipment of one or more phases of the project. Billing sometimes occurs subsequent to revenue recognition, resulting in unbilled accounts receivable. The changes in unbilled accounts receivable and the corresponding amounts recorded in revenue relate to fluctuations in the timing and volume of billings for the Company’s revenue recognized over-time.

Practical Expedients and Exemptions

The Company has elected to adopt certain practical expedients and exemptions as allowed under ASC 606, such as: (i) recording sales commissions as incurred because the amortization period is less than one year; (ii) not adjusting for the effects of significant financing components when the contract term is less than one year; (iii) excluding collected sales tax amounts from the calculation of revenue; and (iv) accounting for the costs of shipping and handling activities that are incurred after the customer obtains control of the product as fulfillment costs rather than a separate service provided to the customer for which consideration would need to be allocated.

Research and Development

The Company incurs research and development (“R&D”) costs during its process of researching and developing new products and significant enhancements to existing products. R&D costs consist primarily of personnel-related costs associated with our team of internal engineers, third-party consultants, materials and overhead. The Company expenses these costs as incurred. R&D expense was $9.9 million, $6.7 million and $8.5 million during the years ended December 31, 2025, 2024 and 2023, respectively, and is recorded within General and administrative expenses in the consolidated statements of operations.

Inflation Reduction Act Vendor Rebates

On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was enacted into law, which includes numerous green energy credits. The section 45X advanced manufacturing production tax credit (“45X Credit”) was established as part of the IRA. The 45X Credit is a per-unit tax credit that is earned over time for each clean energy component domestically produced and sold by a manufacturer. The Company has, and will continue to enter into, arrangements with manufacturing vendors that produce section 45X Credit eligible parts, in which the vendors agree to share a portion of the benefit received related to Array purchases, in the form of “Vendor Rebates.”

The Company accounts for these Vendor Rebates as a reduction of the purchase prices of the vendors’ products and therefore a reduction in the cost of inventory until the inventory is sold, at which time the Company recognizes such rebates as a reduction of Cost of product and service in the consolidated statements of operations. For vendor rebates related to past purchases that are owed to the Company upon execution of the agreement, the Company defers recognition of this portion of the rebate and recognizes the amounts as a reduction to Cost of product and service revenue as future purchases occur. At December 31, 2025 and December 31, 2024, the Company had deferred zero and $8.0 million, respectively, of vendor rebates related to rebates due at contract signing for past purchases, which are included in Other current liabilities in the consolidated balance sheet.

F-23

Array Technologies, Inc.

Notes to Consolidated Financial Statements

During the years ended December 31, 2025 and 2024, the Company recorded reductions to Cost of product and service revenue in the consolidated statements of operations of approximately $165.0 million and $133.3 million, respectively, of which approximately $8.0 million and $38.6 million, respectively, related to the recognition of deferred rebates that were deferred upon contract signing during the years ended December 31, 2024 and 2023, respectively. During the year ended December 31, 2023, the Company recorded a reduction to Cost of product and service revenue in the consolidated statements of operations in the amount of $9.3 million.

As of December 31, 2025, the Company had outstanding Vendor Rebates receivable of $152.0 million and $10.9 million included in Prepaid expenses and other and Other assets, respectively. As of December 31, 2024, the Company had outstanding Vendor Rebate receivables of $115.5 million and zero included in Prepaid expenses and other and Other assets, respectively.

Inflation Reduction Act 45X Credits

The Company accounts for the 45X Credit established by the IRA, under IAS 20 - Accounting for Government Grants and Disclosure of Government Assistance (“IAS 20”), as a reduction to Cost of product and service revenue in the consolidated statements of operations. The tax credit is included as an offset in Income tax payable in the consolidated balance sheets dated December 31, 2025.

During the fiscal years ended December 31, 2025, 2024 and 2023, the Company earned 45X Credits for the manufacturing of certain components, which were sold and resulted in reductions of $8.6 million, $4.4 million and zero, respectively, to Cost of product and service revenue in the consolidated statements of operations.

Warranty Obligations

The Company offers a multi-year assurance type warranty for its products against manufacturer defects and does not contain service elements. For these assurance type warranties, a provision for estimated future costs related to warranty expense is recorded when they are probable and reasonably estimable, which is typically when products are delivered. This provision is based on historical information on the nature, frequency and average cost of claims for each product line. When little or no experience exists for a recently-introduced product line, the estimate is based on comparable product lines. These estimates are re-evaluated on an ongoing basis using best-available information and revisions to estimates are made as necessary. Claims estimated to be payable in the following year are classified as current liabilities and those payable beyond one year are classified as long-term liabilities.

Advertising Expenses

The cost of advertising, marketing and media is expensed as incurred. For the years ended December 31, 2025, 2024 and 2023 advertising expenses totaled $3.6 million, $3.3 million and $2.7 million, respectively, and are recorded within General and administrative expenses in the consolidated statements of operations.

Income Taxes

The Company provides for income taxes based on the provisions of ASC Topic 740 Income Taxes (“ASC 740”), which, among other things, requires that recognition of deferred income taxes be measured by the provisions of enacted tax rates in effect at the date of the consolidated financial statements. A valuation allowance is provided to reduce deferred income tax assets if it is more likely than not that all, or some portion, of such deferred tax assets will not be recognized. Provision for estimated income taxes is based upon elements of income and expense reported in the consolidated statements of operations. The Company also

F-24

Notes to Consolidated Financial Statements

files certain corporate state income tax returns. Generally, the Company is subject to examination by U.S. federal, state and non-U.S. income tax authorities. The current provision for income taxes represents actual or estimated amounts payable on tax return filings each year. Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, and for operating loss and tax credit carryforwards. The change in deferred tax assets and liabilities for the period measures the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws on deferred tax assets and liabilities are reflected as adjustments to the tax provision or benefit in the period of enactment.

The Company determines whether uncertain tax positions are more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position.

The Company recognizes interest and penalties related to unrecognized tax benefits within Interest expense and Other expenses, respectively, in the consolidated statements of operations. The Company's liabilities for unrecognized tax benefits are reflected in Other long-term liabilities in the consolidated balance sheet.

Equity-Based Compensation

The Company recognizes equity-based compensation expense based on the equity award’s grant date fair value. The determination of the fair value of equity awards issued to employees of the Company is based upon the underlying share price and a number of assumptions, including volatility, performance period, risk-free interest rate and expected dividends. The Company values equity awards with a market condition using a Monte Carlo simulation model. The Company accounts for forfeitures as they occur. The grant date fair value of each unit is amortized on a straight-line basis over the requisite service period.

Temporary Equity

Equity instruments that are redeemable for cash or other assets are classified as temporary equity if the instrument is redeemable, at the option of the holder, at a fixed or determinable price on a fixed or determinable date or upon the occurrence of an event that is not solely within the control of the issuer. Redeemable equity instruments are initially carried at the fair value of the equity instrument at the issuance date, which is subsequently adjusted at each balance sheet date if the instrument is currently redeemable, or probable of becoming redeemable. The Series A Redeemable Perpetual Preferred Stock of the Company, par value $0.001 per share (the “Series A Shares”) issued in connection with the Series A Purchase Agreement, as described in Note 11 – Redeemable Perpetual Preferred Stock, are classified as temporary equity in the accompanying consolidated financial statements. The Company elected the accreted redemption value method under which it accretes changes in redemption value over the period from the date of issuance of the Series A Shares to the earliest costless redemption date (the fifth anniversary) using the effective interest method. Such adjustments are included in Preferred cumulative dividends plus accretion and commitment fees on the Company’s consolidated statements of changes in redeemable perpetual preferred stock and stockholders’ equity (deficit) and treated similarly to a dividend on preferred stock in accordance with U.S. GAAP.

Earnings per Share

Basic earnings per share (“EPS”), is computed by dividing net income available to common shareholders by the weighted average shares outstanding during the period. Diluted EPS takes into account the potential dilution that could occur if securities or other contracts to issue shares, such as stock options, unvested restricted stock, or convertible debt, were exercised and converted into shares. The convertible debt is not

currently convertible. Diluted EPS is computed by dividing net income available to common shareholders by the weighted average shares outstanding during the period, increased by the number of additional shares that would have been outstanding if the potential shares had been issued and were dilutive.

Credit Concentration

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and accounts receivable. The Company has no significant off balance sheet concentrations of credit risk. The Company maintains its cash with financial institutions that are believed to be of high credit quality and has not experienced any material losses relating to cash balances.

Our customer base consists primarily of solar developers, independent power producers, utilities and engineering, procurement and construction firms. We do not require collateral on our accounts receivable.

At December 31, 2025, our largest customer and five largest customers accounted for approximately 13.4% and 29.8%, respectively, of total accounts receivable. At December 31, 2024, our largest and five largest customers constituted approximately 9.0% and 31.0%, respectively, of total accounts receivable.

Fair Value

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company follows a fair value hierarchy which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

Three levels of inputs may be used to measure fair value, as follows:

•Level 1 - Quoted prices in active markets for identical assets or liabilities.

•Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 - Unobservable inputs that are supported by little or no market activity that are significant to the fair value of the assets or liabilities.

The fair values of the Company’s cash, accounts receivable, and accounts payable approximate their carrying values due to their short maturities. The carrying value of the Company’s notes payable approximate their fair values, as they are based on current market rates at which the Company could borrow funds with similar terms.

F-26

Notes to Consolidated Financial Statements

The Company follows the provisions of ASC Topic 820 Fair Value Measurement for nonfinancial assets and liabilities measured at fair value on a non-recurring basis. As it relates to the Company, this applies to certain nonfinancial assets and liabilities acquired in business combinations and measurement of goodwill impairment and non-amortizable intangibles and is thereby measured at fair value, which was determined by the Company with the assistance of third-party valuation specialists.

Restructuring

The Company accounts for charges resulting from operational restructuring actions in accordance with ASC Topic 420 Exit or Disposal Cost Obligations ("ASC 420" ) and ASC Topic 712 Compensation - Nonretirement Postemployment Benefits ("ASC 712" ). The Company accrues a liability for termination benefits under ASC 712 when it is probable that a liability has been incurred and the amount can be reasonably estimated and under ASC 420 when the termination benefits are communicated. In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate; changes in these estimates could have a material effect on the amount accrued in the consolidated balance sheets.

Recently Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (the “FASB”) issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures, which requires public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 31, 2026, and for interim periods beginning after December 31, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses, which provides a practical expedient (for all entities) and an accounting policy election (for all entities, other than public business entities, that elect the practical expedient) related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606. The new standard is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, with early adoption permitted. The Company expects to adopt the new guidance in the first quarter of fiscal year 2026 and does not expect a material impact on its consolidated financial statements upon adoption.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software, which updates the accounting for internal-use software by removing project stage references and introduces a new capitalization threshold based on management authorization and project completion probability. The guidance requires evaluation of significant development uncertainty, including novel functionality and unresolved performance requirements. ASU 2025-06 also requires website-specific development costs to be evaluated under the same framework as other internal-use software and clarifies that capitalized internal-use software costs are subject to the property, plant and equipment disclosure requirements under ASC Topic 360 Property, Plant, and Equipment. The amendments are effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. ASU 2025-06 may be applied prospectively, retrospectively or on a modified transition approach with early adoption permitted. The Company is currently evaluating the impact of ASU 2025-06 on its financial statement disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting: Narrow-Scope Improvements, which provides clarity and navigability of interim reporting requirements, requiring the entities to provide interim financial statements and notes in accordance with U.S. GAAP and added a comprehensive list of interim disclosures required by U.S. GAAP. The new standard is effective for the Company beginning in fiscal year 2029 with early adoption permitted. The Company is currently evaluating the impact of ASU 2025-11 on its financial statement disclosures.

Recently Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. The Company adopted ASU 2023-09 during the year ended December 31, 2025, with retrospective application.

3. Acquisition

On August 14, 2025 (the “Closing Date”), the Company, through its indirect wholly owned subsidiary STINorland USA, Inc., a California corporation (“Buyer”), completed the APA Acquisition, pursuant to the terms of the equity purchase agreement, dated as of June 17, 2025, by and among the Company, Buyer, APA, SunHoldings, LLC, an Ohio limited liability company (“Seller”), and the guarantors party thereto (as amended, the “Purchase Agreement”). The cash consideration paid was approximately $166.1 million. The Purchase Agreement also includes an earnout provision estimated to have a fair value of approximately $19.3 million as of the Closing Date (the “Earnout Consideration”), under which the Seller may receive shares of Company common stock, or equivalent cash value at the Buyer’s discretion, based upon APA’s achievement of certain financial performance targets during the three-year period ending on September 30, 2028. As a result, the purchase consideration approximates $185.4 million. Subject to the terms and conditions set forth in the Purchase Agreement, the Company has also agreed to pay aggregate deferred consideration of approximately $40.0 million payable in three installments over a two-year period based on service within five business days after the first and second anniversaries from the Closing Date and as set forth below (the “Deferred Consideration”). Each of the Earnout Consideration and Deferred Consideration are described in more detail below. The Company is currently finalizing the valuation of the acquired assets and liabilities and assessing the related accounting impacts.

The purchase consideration to acquire APA consisted of the following:


Cash consideration paid	166,135
Earn-out	19,256
Purchase consideration	$	185,391

are issued) exceeds $90 million. The Purchase Agreement provides that, to the extent the issuance of any Earnout Consideration or Deferred Consideration Shares would require stockholder approval under Nasdaq Listing Rule 5635(a), the Company will pay cash in lieu of issuing such shares, unless such stockholder approval has been obtained. The principal Seller continues to assume the managerial responsibilities of APA.

The Earnout Consideration is accounted for as contingent consideration, and the fair value is estimated each reporting period. As of the Closing Date, the Earnout Consideration was estimated to have a fair value of approximately $19.3 million using a Monte-Carlo simulation method. Changes in fair value of the contingent liability are recognized in Change in fair value of contingent consideration in the consolidated statements of operations. Estimating the amount of payments that may be made under the Earnout Consideration is by nature imprecise. The significant fair value inputs used to estimate the future expected Earnout Consideration payments to Seller include a discount rate, earnings forecasts, and actual and estimated future volatility in the Company’s stock price.

Deferred Consideration Installments

The Deferred Consideration which will be payable to Seller in three installments (each, a “Deferred Consideration Installment”): (i) within five business days after the first anniversary of the Closing Date, an amount equal to 50% of the Deferred Consideration; (ii) on December 31, 2026, an amount equal to (A) 50% of the Deferred Consideration multiplied by (B) the proportion of the two-year period from the Closing Date to the second anniversary of the Closing Date that has elapsed as of December 31, 2026; and (iii) within five business days after the second anniversary of the Closing Date, an amount equal to the remaining balance of the Deferred Consideration. As more fully described in the Purchase Agreement, the Deferred Consideration Installments are subject to reduction if certain equity holders of Seller cease to be employees of the Company under certain circumstances. Each Deferred Consideration Installment will, at the Company’s election, be paid: (i) in cash; (ii) through the issuance of shares of Company common stock, par value $0.001 per share, valued at the closing price on the trading day immediately preceding the applicable Deferred Consideration Anniversary (if any such shares are issued, the “Deferred Consideration Shares”); or (iii) by any combination of the foregoing. As the Deferred Consideration Installments are tied to future service to the Company, they are considered compensatory and not included in purchase consideration.

Purchase Price Allocation

The APA Acquisition was accounted for as a business combination applying ASC 805. The allocation of the purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed was based on their estimated fair values as of the date of acquisition. Goodwill was calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The factors contributing to the recognition of goodwill were the expected synergies of the combined entities that are expected to be realized from the APA Acquisition. The goodwill is deductible for tax purposes.

The amounts recorded as of December 31, 2025 are preliminary, as the Company is finalizing working capital, post-closing, and other customary adjustments. These preliminary estimates are subject to change within the measurement period (defined as the twelve months following the Closing Date) and related accounting adjustments may be materially different, as the Company obtains additional information on these matters and as additional information is made known during the post-acquisition measurement period. As a result of further refining its estimates and assumptions since the date of the acquisition, the Company recorded measurement period adjustments to the initial opening balance sheet as shown in the table above. There were no measurement period adjustments materially impacting earnings that would have been recorded in previous reporting periods if the adjustments had been recognized as of the acquisition date.

The intangible assets are being amortized over their estimated useful lives on a straight-line basis that reflects the economic benefit of the asset. The determination of the useful lives is based upon various industry studies, historical acquisition experience, economic factors, and future forecasted cash flows of the Company following the APA Acquisition. Direct transaction costs incurred related to the APA Acquisition were $9.4 million and are included in General and administrative expenses in the consolidated statements of operations.

Included in the Company’s consolidated statements of operations from the Closing Date of August 14, 2025 through December 31, 2025 are revenue of $50.0 million and an operating loss of $6.3 million, inclusive of $7.5 million of expenses related to the Deferred Consideration and $6.4 million of amortization expense related to identified intangible assets.
