Item 1A. Risk Factors

You should carefully consider the following discussion of significant factors, events and uncertainties in evaluating our business and the forward-looking statements contained in this Annual Report on Form 10-K. The risks described below could materially and adversely affect our business, operating results, liquidity and financial condition. Although we believe we have identified and discussed the principal risks affecting our business, these risk factors may not be exhaustive, and additional risks and uncertainties—whether currently known or unknown, or not presently considered material—could also have a material adverse effect on our business, results of operations or financial condition in the future. In addition to the current and potential trade and tariff policies and their effects on our business and operations discussed in Item 7 of this Form 10-K and in the risk factors below, additional or unforeseen effects of such policies could give rise to, or exacerbate, the risks described herein.

Risks Related to Our Business and Our Industry

If demand for solar energy projects diminishes, we may not be able to grow, and our financial results, business and prospects could be materially adversely impacted.

A significant portion of our business continues to be derived from solar energy projects, and our future success performance remains closely tied to demand for solar energy solutions and the timing of project development and execution. The solar industry has historically been cyclical and subject to periods of slowed sector-wide growth and project delays. In 2023 and 2024, the domestic utility-scale solar market experienced meaningful project delays that pushed execution beyond originally expected timelines and reduced near-term demand for our products.

Demand for solar energy projects may be adversely affected by a variety of factors, many of which are outside of our control, including permitting and interconnection challenges; project financing conditions; lingering uncertainty regarding U.S. energy and trade policy frameworks, potential changes the IRA to solar projects; supply chain constraints; anti-dumping and countervailing duty matters, and broader macroeconomic conditions. Delays or cancellations of solar projects can negatively impact our results due to the long lead times, customized engineering, and project-specific nature of our solutions.

While we have expanded our offerings to support BESS, data center and other adjacent mission-critical energy infrastructure markets, these markets are at varying stages of development and adoption, and their growth may not offset declines or delays in solar project activity on the timing or scale we expect. Increased demand from emerging applications, including energy storage and data center infrastructure driven by artificial intelligence and grid constraints, as well as emerging and developing global economies, may take years to materialize and is subject to market acceptance, regulatory developments, customer investment decisions and our ability to successfully position and scale our solutions in those markets. There is no assurance that such opportunities, or our ability to benefit from them, will materialize.

Our future performance depends in part on the pace and scale of development of new power-consuming facilities, including data centers, and on market acceptance of emerging technologies such as artificial intelligence. If these opportunities do not develop as we expect, if their timing or growth rate is slower than anticipated, or if we are unable to effectively position our solutions to meet these opportunities, our growth and results of operations could be adversely affected.

The solar industry remains subject to demand volatility, and our ability to forecast future performance is complicated by the evolving and competitive nature of the market and recent project delays. Demand for solar

Table of Contents

energy projects may be affected by factors largely outside of our control, including the relative cost, reliability and performance of solar energy systems compared to conventional and other renewable energy sources; the availability and scope of government subsidies and incentives; energy commodity prices; levels of customer investment, particularly during periods of economic uncertainty; and the emergence or increased support of alternative energy technologies.

If demand for solar energy projects remains weak or projects continue to be delayed, and if our product offering expansion efforts do not develop as expected or on anticipated timelines, demand for our products could decline, which could materially adversely affect our business, financial condition, results of operations and prospects.

If we fail to accurately estimate the potential losses related to the wire insulation shrinkback matter, or fail to recover the costs and expenses incurred by us from the supplier, our profit margins, financial results, business and prospects could be materially adversely impacted.

As previously disclosed, the Company was notified by certain customers that a subset of wire harnesses used in its EBOS solutions presented unacceptable levels of contraction of wire insulation (“wire insulation shrinkback”). Based upon the Company’s assessment, the Company currently believes the wire insulation shrinkback is related to defective wire manufactured by Prysmian Cables and Systems USA, LLC (“Prysmian”). Based on the Company’s continued analysis of available information obtained throughout the remediation process, the Company determined that a potential loss was both probable and reasonably estimable and has continued to refine its assumptions based on additional information obtained throughout the remediation process. Based on the Company’s continued analysis of information available as of the date of this Annual Report on Form 10-K, the estimate of potential losses is $73.0 million. The estimated liability is based on several assumptions. As additional information becomes available, which may include additional reports of wire insulation shrinkback at previously affected and reported solar projects or at projects not previously reported or otherwise identified, the Company may increase its estimated warranty liability from its current estimate, and such increase may be material.

Our warranty liability for this matter is based on several assumptions, including estimated failure rates, the potential magnitude of engineering, procurement and construction firms’ labor cost to identify and perform the repair and replacement of impacted harnesses, materials replacement cost, planned remediation method, and inspection costs. We do not have a long history of making assumptions relating to warranties. As a result, these assumptions could prove to be materially different from our current estimate, causing us to incur substantial unanticipated expenses to identify, repair or replace the defective wire or to compensate customers. Additionally, changes to the planned remediation method and additional information about weather delays, site access, replacement scope, and vegetation management could also have a material impact on the warranty liability. Our failure to accurately estimate this liability could result in unexpected volatility to our Class A common stock and have a material adverse effect on our financial condition.

The Company does not maintain insurance for product warranty and has commenced a lawsuit against Prysmian, as discussed in more detail under Litigation in Note 15 - Commitments and Contingencies in our consolidated financial statements included in this Annual Report on Form 10-K. Because the lawsuit against Prysmian is ongoing, potential recovery from Prysmian is not considered probable as defined in Accounting Standards Codification (“ASC”) 450, and has not been considered in our estimate of the warranty liability as of December 31, 2025. In addition, the results of the litigation against Prysmian are inherently uncertain and we cannot guarantee the outcome of that litigation. Litigation can be expensive and time consuming and will divert the efforts of our management and other personnel, which could harm our business, whether or not such litigation results in a determination favorable to us. If we fail to recover the costs and expenses incurred by us

Table of Contents

in connection with the identification, repair and replacement of the defective Prysmian wire, our financial results, business and prospects could be materially adversely impacted. Our actual loss in this matter is uncertain and may have a material adverse effect on our business, financial condition and results of operations.

Similar to our other products, the defective wires associated with the wire insulation shrinkback matter expose us to potential product liability claims. For more information, see the risk factor below related to defects or performance problems in our products or their parts.

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

We source certain raw materials used to manufacture our components and system solutions from vendors outside the United States. Ongoing changes in international relations and tariff regimes, particularly between the U.S. and China, as well as uncertainty regarding China-Taiwan relations could adversely impact the availability and cost of components and our ability to produce our components at targeted levels. We cannot predict whether additional trade restrictions, including increased tariffs, border taxes, embargoes, safeguards and customs restrictions, will be imposed by the U.S. or other foreign governments. Continued economic uncertainty, escalation of trade tensions, geopolitical conflicts, foreign currency fluctuations, natural disasters; public health events, theft, restrictions on the transfer of funds, the financial instability or bankruptcy of vendors, and significant labor disputes and disruptions, their effects or the perception of their effects could further impair our supply chain, increase logistics and input costs, or delay production and adversely affect our business, financial condition and results of operations.

We are subject to risks from changes to trade restrictions, import tariffs, anti-dumping and countervailing duties. Such changes could adversely affect the amount or timing of our revenue, results of operations or cash flows.

Changes or the threat of changes in import and export policies, including customs and trade restrictions, new or increased tariffs or quotas, sanctions, embargoes, or safeguards by the U.S. and/or other foreign governments could require changes in the manner in which we conduct business and adversely affect our financial condition, results of operations, reputation and our relationships with customers, suppliers and employees in the short- or long-term. Additionally, such policy changes or instability can impact our supply chain, including our ability to acquire raw materials and to timely manufacture our components and system solutions. Further, significant changes to trade policy may impact our ability to source our required raw materials from alternative vendors due to increased demand, which could reduce or delay the supply of raw materials available to us. Changes in trade policy, including retaliatory actions from governments, may result in higher costs, and we may not be able to pass such resulting increases in raw material costs to our customers. Additionally, if the price of solar systems in the U.S. increases, its use could become less economically feasible and could reduce our gross profits or reduce the demand of solar systems manufactured and sold, which in turn may decrease demand for our products. Such outcomes could adversely affect the amount or timing of our revenue, results of operations or cash flows, and continuing uncertainty could cause sales volatility, price fluctuations or supply shortages or cause our customers to advance or delay their purchase of our products.

For example, on February 1, 2025, the U.S. government announced 10% tariffs on product imports from China. China imposed retaliatory 10% tariff measures on U.S. goods. Both the U.S. and China have suspended heightened tariff imposition until November 2026. If maintained, the newly announced tariffs and the potential escalation of trade disputes could pose a significant risk to our business and would affect our revenue and cost of goods sold. The extent and duration of the tariffs and the resulting impact on general

Table of Contents

economic conditions and on our business are uncertain and depend on various factors, such as negotiations between the U.S. and affected countries, the responses of other countries or regions, exemptions or exclusions that may be granted, availability and cost of alternative sources of supply, and demand for our products in affected markets. Further, actions we take to adapt to new tariffs or trade restrictions may negatively affect key customers, suppliers, and manufacturing partners and cause us to modify our operations, forgo potential business opportunities, or lose awarded business opportunities. Given the global complexity of trade policy, 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 have modified, and in the future may modify, our business strategy to abandon lines of business or implement new lines of business. Modifying our business strategy could have an adverse effect on our business and financial results.

From time to time, we review our business strategy and, have in the past modified it, and may in the future do so again. We previously abandoned efforts to penetrate the electric-vehicle market due to specific industry challenges and are currently developing solutions seeking to further penetrate the CC&I market, BESS market, data centers market, the OEM market and international markets. Abandoning lines of business has in the past led to, and in the future may lead to, increased costs, loss of customers, our reputation being negatively impacted, and our failure to fully recoup the investments made in those lines of business. Implementing new lines of business also poses challenges including with respect to our ability to build a well-recognized and respected brand in that specific industry, expanding our customer base, improving and maintaining operational efficiency for new lines of business, and anticipating and adapting to changing market conditions, including technological development and changes in competitive landscape. Shifts in business strategy can and have made it more difficult for us to collect data and accurately forecast our production and material needs, price our goods and services, and estimate our margins. Failure to successfully manage the risks of modifying our business strategy could have a material adverse effect on our business, financial condition and results of operations.

Amounts included in our backlog and awarded orders may not result in actual revenue or translate into profits.

As of December 31, 2025, we had $747.6 million of backlog and awarded orders. Backlog of $326.2 million represents signed purchase orders or contractual minimum purchase commitments with take-or-pay provisions and awarded orders of $421.4 million are orders we are in the process of documenting a contract but for which a contract has not yet been signed. In 2025, backlog and awarded orders increased compared to 2024 and 2023. We cannot guarantee that our backlog or awarded orders will maintain its current growth levels, or that awarded orders will become backlog or that backlog will result in actual revenue in the originally anticipated period or at all. In addition, the contracts included in our backlog or awarded orders may not generate margins equal to our historical operating results. Our customers have experienced project delays and may cancel orders as a result of external market factors and political, economic, supply chain or other factors beyond our control. If our backlog and awarded orders fail to result in revenue at all or in a timely manner, we could experience a reduction in revenue, profitability and liquidity.

Defects or performance problems in our products or their parts, whether due to manufacturing, installation, or use, including those related to the wire insulation shrinkback matter, have a high consequence of failure and can lead to equipment and systems failure, physical injury or death, and in the past have, and in the future could, result in loss of customers, reputational damage and decreased revenue, and materially adversely impact our business, financial condition and results of operations.

Table of Contents

EBOS components, including the wires related to the wire insulation shrinkback matter, whether manufactured by us or third party suppliers, are products and systems for which the consequences of failure are significant and can include, among other issues, equipment damage, fire damage, and even serious injury or death because of the high voltages involved and potential for fire.

Although we conduct quality assessments on our products and these products are manufactured according to stringent quality requirements, they may contain undetected errors or defects, especially when first introduced or when new generations are released. Errors, defects, product failures, destruction or poor performance can arise due to design flaws, defects in raw materials or components or manufacturing difficulties, installation or system failures, which can affect both the quality and the yield of the product. Any such issues, including those related to the wire insulation shrinkback matter, could result in shipment delays, rejection of products, replacement or recall of products, reputational harm, lost revenue and increased costs.

Furthermore, defective components may give rise to warranty claims (such as those related to the wire insulation shrinkback matter), or indemnity or product liability claims against us, that may exceed any revenue or profit we receive from the affected products. While we accrue reserves for warranty claims, our warranty accruals are based on assumptions regarding future product performance, and we have limited historical experience making such assumptions for certain products. If these assumptions prove inaccurate, we may incur substantial unanticipated expenses to repair or replace defective products or to compensate customers for defective products, which could materially and adversely affect our financial condition and results of operations.

If one of our products, including those involved in the wire insulation shrinkback matter, causes injury or property damage, we could be exposed to product liability claims. The successful assertion of a product liability claim against us could result in significant monetary damages, penalties or fines, adverse publicity, reputational damage, loss of competitive position, and reduced sales of our products. In addition, product liability claims or defects involving other companies in the solar industry could negatively affect market perceptions of the industry , which may adversely affect our ability to attract new customers and harm our growth and financial performance.

We have experienced, and may experience in the future, delays, disruptions, quality control or reputational problems in our manufacturing operations in part due to our vendor concentration.

Our product development, manufacturing and testing processes are complex, involve a number of precise steps from design to production, and require significant technological and production process expertise, and therefore we depend on a limited number of vendors and suppliers. Any vendor delay or disruption could cause a delay or disruption in our ability to meet customer requirements which may result in a loss of customers. Any change in our processes could cause one or more production errors, requiring a temporary suspension or delay in our production line until the errors can be researched, identified and properly addressed and rectified. This may occur particularly as we introduce new products, modify our engineering and production techniques, and/or expand our capacity. In addition, our failure to maintain appropriate quality assurance processes could result in increased product failures, loss of customers, increased warranty reserve, increased production and logistics costs and delays. In addition, our reliance on a limited number of manufacturing and production facilities, vendors and suppliers may result in increased concentration risk, and this concentration may increase over time as we adjust or consolidate our manufacturing footprint, vendor relationships or sourcing strategies. Any further concentration could reduce our ability to mitigate disruptions, limit our flexibility to transition to alternative facilities, sources or suppliers, and amplify the impact of operational, quality, capacity or compliance issues affecting our Company. Any of these developments could have a material adverse effect on our business, financial condition, and results of operations.

Table of Contents

We do not control our vendors or suppliers or their business practices and our oversight of their actions is limited. Accordingly, we cannot guarantee that they follow quality control, ethical or other desired business practices. If vendors or suppliers fail to comply with applicable laws, regulations, quality standards, safety codes, employment practices, human rights standards, environmental standards, production practices, or diverge from labor practices generally accepted as ethical in the U.S. or other markets in which we do business, we could attract negative publicity and harm our reputation and business. In certain cases, identifying, qualifying and transitioning to alternative suppliers or components may require engineering validation, testing or customer approval, which can take time and may not be feasible within project schedules. As a result, supply disruptions or vendor issues may not be readily mitigated and could have a material adverse effect on our business, financial condition, and results of operations.

If we fail to retain our key personnel and attract additional qualified personnel, our business strategy and prospects could 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, key technical personnel and other qualified employees, 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 in identifying, hiring and retaining qualified personnel in many areas of our business.

An inability to attract and retain senior and middle management, an inability to effectively provide for the succession of senior management, or an inability to attract and retain other key or qualified personnel could limit or delay our ability to execute our business strategy, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our products are primarily manufactured and shipped from our production facilities in Tennessee, and any damage or disruption at these facilities may harm our business.

A significant portion of our operations is located in our Tennessee manufacturing facilities. Issues with our workforce, including illness or absenteeism, unionization initiatives or difficulties in recruiting and retaining skilled workers in the area may have a material adverse effect on our business. Further, our geographic concentration exposes us to increased risk with regards to natural disasters, including tornados, fire, power interruption or other calamity at any one of our facilities, or any combination thereof. Any such disruption or unanticipated event may cause significant interruptions or delays in our business and the reduction or loss of inventory may render us unable to fulfill customer orders in a timely manner, or at all, and may result in lawsuits. Certain of the equipment used to manufacture our products could be difficult, time consuming, or costly to replace or repair if damaged. Our property and business disruption insurance coverage may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all.

We may face difficulties integrating and optimizing our consolidated Tennessee-based manufacturing and distribution operations and may not fully realize the anticipated benefits.

In 2024, we announced plans for significant capital investment to expand and consolidate our Tennessee-based manufacturing and distribution operations at a new facility in Portland, Tennessee. The expansion and consolidation were launched in the fourth quarter of 2025 with the opening of our 638,000-square-foot Mega Plant; however, we continue to integrate, ramp up, relocate and optimize operations in the new facility.

Table of Contents

The development, transition and integration of a large, consolidated manufacturing and distribution facility are complex and have involved, and may continue to involve, operational challenges, including inefficiencies during ramp-up, higher-than-expected costs, supply chain disruptions, quality control issues, workforce coordination challenges and delays in achieving expected operational performance. These efforts may also exacerbate geographic concentration risks described elsewhere in this Annual Report on Form 10-K. In addition, the time and expense required to stabilize operations and achieve anticipated efficiencies and cost savings may be greater than expected, and there can be no assurance that the anticipated benefits of the consolidation will be fully realized, or realized within expected timeframes.

Any of the foregoing could materially adversely affect our business, financial condition, results of operations and prospects and could cause our actual results to differ materially from our expectations or projections.

Safety issues may subject us to penalties, negatively impact customer relationships, result in higher operating costs, and negatively impact employee morale and turnover.

We have manufacturing facilities that are susceptible to numerous industrial safety risks that can lead to personal injury, loss of life, and damage to property and equipment. Even with precautions to avoid incidents, we have experienced accidents in the past and may again in the future, which can negatively affect our safety record. A poor safety record can harm our reputation with existing and potential customers, jeopardize our relationship with employees in a competitive labor market, increase our insurance and operating costs and could adversely impact our business and results of operations.

The market for our products is competitive, and we face increased competition as new and existing competitors introduce EBOS system solutions and components, which could negatively affect our results of operations and market share.

The market for EBOS system solutions and components is competitive. Our principal competitors include Construction Innovation, Hikam America, Inc., Nextpower (via acquisition of Bentek), Premier PV, TerraSmart, LLC (formerly SolarBOS, Inc.), and Voltage, LLC. We compete on the basis of product performance and features, installation cost, reliability and duration of product warranty, sales and distribution capabilities, packaging and transportation, and training and customer support. Competition continues to intensify as new and existing competitors enter the market. If our competitors introduce new technologies that are successful in offering price competitive and technological attractive EBOS system solutions and components, it may become more difficult for us to maintain market share.

Our existing and potential competitors may have greater financial, technological or operational resources, enabling them to offer products at aggressive pricing levels, develop new or enhanced technologies more quickly, or enter into strategic partnerships that strengthen their competitive position. Competitive pricing pressures, including discounting and volume-based pricing, have affected, and may continue to affect, our revenue and gross profit. In addition, if we are unable to respond effectively to technological changes, adopt alternative or enhanced solutions, or execute timely innovation and development initiatives, our products may become less competitive or obsolete, which could result in lost market share, reduced revenue and diminished margins.

Macroeconomic conditions, including high inflation, high interest rates, and geopolitical instability impacts our business and financial results.

Table of Contents

Global markets have experienced significant volatility in recent years due to macroeconomic conditions such as elevated inflation, capital market volatility, supply chain disruptions and broader geopolitical instability.

These conditions have increased economic uncertainty, negatively affected demand for our products, lengthened our sales cycles, and made access to capital more difficult and costly. Inflationary pressures have increased energy, freight and other operating costs, while high interest rates have increased borrowing costs for both us and our customers.

In addition, a reduction in the availability of project debt capital or an increase in the cost of financing may make it more difficult for end customers to finance solar energy projects and could reduce demand for our products. While government subsidies and economic incentives currently support the adoption of solar energy, there is no assurance that such incentives will remain in place, be extended or be available on favorable terms. Many end users depend on financing and incentives to fund the capital expenditures required to construct solar energy projects, and changes in these programs could adversely affect project economics.

Higher interest rates may also lower expected returns on solar energy investments, increase required equity contributions, or make alternative investments more attractive relative to solar energy projects, which could cause end users to delay, reduce or forego investment in solar projects. While we continue to monitor and evaluate strategies to mitigate the impact of macroeconomic conditions, there can be no assurance that worsening economic conditions will not materially and adversely affect our business, financial condition, results of operations or liquidity.

We are subject to risks related to our ability to protect, enforce, and defend our intellectual property.

Our success depends in significant part on our ability to obtain, maintain, protect, enforce and defend 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 other contractual arrangements, to protect our technology and competitive position. These protections may be limited in scope and may not prevent competitors from duplicating, designing around or otherwise exploiting our technology, or from independently developing competing products.

We have applied for patents in the U.S. and abroad, some of which have been issued, but we cannot guarantee that pending patent or other intellectual property registration applications will be granted, that our intellectual property rights will be sufficiently broad, or that our issued patents, trademarks or trade names will not be opposed, contested, challenged, invalidated, circumvented, or rendered unenforceable. Any failure to obtain or maintain adequate intellectual property protection could impair our ability to commercialize our products, require product redesigns or rebranding, or adversely affect our competitive position.

As disclosed under Litigation in Note 15 - Commitments and Contingencies to our consolidated financial statements included in this Annual Report on Form 10-K, we have filed patent infringement complaints with the U.S. International Trade Commission (“ITC”) and in U.S. District Courts against certain competitors. These proceedings are costly and uncertain and place our asserted patents and other intellectual property at risk of being invalidated or interpreted in a manner that permits competing products to be imported and sold in the United States. If we are unsuccessful, we could lose revenue and face increased competition from the defendants or other third parties. In addition, enforcement actions may prompt counterclaims or other challenges to our intellectual property rights before courts or administrative bodies.

We also rely on trade secrets, nondisclosure agreements and trademarks to protect proprietary information and brand recognition; however, these measures may not be effective in preventing misuse,

Table of Contents

misappropriation or infringement, particularly in jurisdictions with less developed intellectual property enforcement regimes. Any inability to protect, enforce or defend our intellectual property, or the incurrence of significant costs in doing so, could materially adversely affect our business, financial condition and results of operations.

Acquisitions, joint ventures and/or investments and the failure to integrate acquired businesses, could disrupt our business and negatively impact our results of operations.

Our success depends, in part, on our ability to expand our product offerings and grow our business in response to changing technologies, customer demands and competitive pressures. In some circumstances, we may pursue growth through the acquisition of complementary businesses, solutions or technologies or through joint ventures or investments. The identification of suitable candidates can be difficult, time-consuming and costly, and we may not be able to successfully complete identified acquisitions or joint ventures.

Achieving anticipated benefits and synergies from acquisitions is uncertain and subject to various risks, including our ability to integrate or benefit from acquired technologies or services in a profitable manner; diversion of capital and other resources, including management’s attention; unanticipated costs or liabilities related to the acquisition; failure to leverage the increased scale of the combined businesses quickly and effectively; the potential impact of the acquisition on our relationships with employees, customers, suppliers and other business partners; challenges associated with integrating personnel, operations and retaining key employees; and potential litigation. Many of these factors will be outside of our control and any one of them could result in increased costs, decrease in expected revenues and diversion of management’s time and attention, which could materially impact the combined company. The full benefits of an acquisition may not be realized within the anticipated time frame or at all. All of these factors could decrease or delay the expected accretive effect of acquisitions and negatively impact our results of operations.

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.

A small number of customers have historically accounted for a material portion of our revenue. For the year ended December 31, 2025, our largest customer and five largest customers constituted approximately 19.1% and 53.7% of total revenue, respectively. As a result of this customer concentration, certain customers may have greater bargaining leverage, which could increase pricing pressure or influence the commercial terms on which we transact with such customers and adversely affect our margins, cash flows and results of operations. Further, the Company’s trade accounts receivable are from companies within the solar industry, and as such, the Company is exposed to industry credit risks. As of December 31, 2025, our largest customer and five largest customers constituted 25.2% and 46.8% of trade accounts receivable, respectively. Accordingly, loss of our largest customer or other significant customers, a significant reduction in pricing or order volume from our largest customer or other significant customers, their inability to perform under their contracts, or their default in payment could adversely reduce net sales and operating results in any reporting period.

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

Significant decreases in the price of electricity, whether in organized electric markets or with contract counterparties, may negatively impact owners of 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

Table of Contents

decrease as a result of: (i) increased deployment of lower-cost electricity generation technologies or facilities, including renewable, conventional or alternative energy sources; (ii) reductions in fuel prices or other input costs used in electricity generation; (iii) changes in governmental policies, utility rate structures, subsidies or regulatory frameworks that reduce electricity prices; (iv) improvements in transmission, grid, energy-management or energy-storage technologies that increase access to or efficiency of lower-cost power; and (v) changes in electricity consumption patterns, load profiles or end-user demand that reduce overall electricity demand or shift usage to lower-cost alternatives.

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 and results of operations may be harmed.

Failure of our information technology systems, including those managed by third parties, or cybersecurity incidents could disrupt our operations and adversely affect our results of operations.

We rely extensively on information technology systems, including data centers, hardware, software and third-party applications, to operate our business, manage logistics and inventory, process transactions, communicate internally and externally, and generate financial and operational reports. Certain aspects of our business also involve the collection, use, storage and transmission of personal, confidential and sensitive information relating to customers, end users, employees, suppliers and the Company. The integrity, confidentiality, security and availability of these systems, including those operated by third-party service providers, are critical to our operations.

Our information technology systems and those of our third-party vendors are subject to risks from cybersecurity incidents, unauthorized access, system failures, human error, power outages, natural disasters and other disruptive events. The risk of cyberattacks and intrusions has increased as the number, sophistication and intensity of such incidents continue to grow, including those perpetrated by organized crime groups and nation-state actors, and as a result of increased capabilities of artificial intelligence. We have been, and expect to continue to be, the target of fraudulent communications and other cyber threats, and we have experienced immaterial cybersecurity incidents. Although we maintain cybersecurity safeguards and cyber liability insurance, these measures may not be sufficient to prevent or fully mitigate all incidents or losses, and insurance coverage may be unavailable or insufficient.

Any actual or perceived failure of our information technology systems, including disruptions caused by system upgrades, integrations, or reliance on third-party service providers, or any unauthorized access to or disclosure of personal, confidential or sensitive data, could disrupt our operations, harm our reputation, reduce customer confidence, result in lost sales, and expose us to regulatory scrutiny, litigation or other liabilities. In addition, compliance with evolving data protection, cybersecurity and incident disclosure requirements may increase our costs, and any failure to comply could subject us to fines, penalties or other regulatory actions. Any of the foregoing could materially adversely affect our business, financial condition, results of operations and prospects.

Our expansion outside the U.S. could subject us to additional business, financial, regulatory and competitive risks.

We continue to work on enhancing our geographic focus outside of the U.S., with a primary focus on Southern Europe, Australia and the Pacific Region. Our expansion outside of the U.S. involves developing region-specific products; 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; creating

Table of Contents

international subsidiaries to build credibility and market presence; and utilizing locally sourced components in our products in jurisdictions where it is required. In addition, we have begun executing on expansion opportunities in other international markets, including Latin America, through the supply of our products for solar energy projects, which may expose us to additional regulatory, commercial and operational risks associated with operating in new jurisdictions.

Our products and services to be offered outside of the U.S. 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 reengineering 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, international political or economic conditions, restrictions on the repatriation of earnings, longer sales cycles, warranty expectations, product return policies and cost, performance and compatibility requirements. In addition, expanding into new geographic markets increases 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 Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”). The FCPA generally prohibits companies and their intermediaries from making improper payments to foreign government officials for the purpose of obtaining or retaining business. Other countries in which we operate and may operate in the future may also have anti-bribery laws. Our policies mandate compliance with these anti-bribery laws. However, we currently operate in and intend to further expand into, many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. It is possible that our employees, subcontractors, agents and partners may take actions in violation of our policies and anti-bribery laws. Any such violation, even if prohibited by our policies, could subject us to criminal or civil penalties or other sanctions, which could have a material adverse effect on our business, financial condition, cash flows and reputation.

Failure to manage the risks and challenges associated with our potential expansion into new geographic markets could adversely affect our revenue and our ability to achieve or sustain profitability.

Our indebtedness could adversely affect our financial flexibility, restrict our current and future operations, and our competitive position.

As of December 31, 2025, we had $136.8 million revolving loans outstanding under the Senior Secured Credit Agreement. Our indebtedness could have 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; reduce 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 our industry; restrict us from pursuing business opportunities; making it more difficult to satisfy financial obligations; place us at a disadvantage compared to our competitors that have less debt; and limit our ability to borrow additional funds. We may also be unable to generate sufficient cash to pay any amounts due.

In addition, the Senior Secured Credit Agreement contains, and the agreements evidencing or governing any other future indebtedness may contain, restrictive covenants that limit our ability to engage in activities that may be in our long-term best interests. Furthermore, we are required to maintain compliance with

Table of Contents

various financial ratios in the Senior Secured Credit Agreement. A failure by us to comply with the covenants or to maintain the required financial ratios contained in the Senior Secured Credit Agreement could result in an event of default under such indebtedness, which could adversely affect our ability to respond to changes in our business and manage our operations. A default by us under the Senior Secured Credit Agreement or an agreement governing any other future indebtedness may trigger cross-defaults and acceleration under any other future agreements governing our indebtedness. If any of our indebtedness is accelerated, there can be no assurance that our assets will 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.

Risks Related to Regulatory Matters

Existing electric utility industry, federal state and municipal renewable energy and solar energy policies and regulations, including zoning and siting laws, and any subsequent changes, present technical, regulatory and economic barriers to the purchase and use of solar energy systems that may significantly reduce 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, and system permitting, interconnection and operating requirements can deter purchases of renewable energy products, including solar energy systems, by reducing anticipated revenue or increasing costs or regulatory burdens for would-be system purchasers. Any resulting reductions in demand for solar energy systems could harm our business, prospects, financial condition and results of operations.

Renewable portfolio standards (“RPS”) and clean energy standards (“CES”) are key policies intended to promote solar and renewable electricity. Currently, over half of the U.S. states, the District of Columbia, and Puerto Rico have implemented some form of RPS/CES policy, which mandates that a certain portion of electricity delivered by regulated utilities to customers come from a set of eligible renewable or clean energy resources by a certain compliance date. Additionally, several states have set voluntary renewable energy goals. RPS/CES policies vary widely by jurisdiction. In some areas, requirements have been satisfied and utilities must only prevent reductions in qualifying energy purchases and sales, while in other jurisdictions, RPS/CES policies continue to require substantial increases, up to 100 percent renewable electric generation, with final compliance dates typically 20 or more years out. Proposals to extend compliance deadlines, reduce renewable requirements or solar set-asides, or entirely repeal RPS/CES policies emerge periodically in various jurisdictions. There can be no assurance that state RPS/CES policies or other policies supporting renewable energy will continue.

Additionally, states, counties, and municipalities have the ability to slow or obstruct the development of new solar projects by using permitting, zoning and siting laws. Many states that support the renewable energy sector have tried to limit the ability of counties or municipalities to block solar development in this way. In some states, the public utility commissions or other State agencies have authority to preempt local zoning decisions that unreasonably interfere with solar development. Other states effectively allow municipalities and counties to exercise their standard land use powers. In the future, the approach taken in individual states may change and will be driven by the political climate in those states. There is no guarantee that states will continue to enact zoning and permitting laws that support the renewable energy sector.

Net metering policies for on-site solar have also promoted solar electricity by allowing solar PV system owners to only pay for power usage net of production from the solar PV system. Under a net metering program, the customer typically pays for the net energy used or receives a credit against future bills if more energy is produced than consumed. While most U.S. states have adopted some form of net metering for small solar projects, these programs have recently come under regulatory scrutiny in some jurisdictions due to allegations that net metering policies inequitably shift costs onto non-solar ratepayers. A number of states have made changes to net metering programs that lessen the benefits associated with net metering. Net metering policies may in the future be modified or even eliminated in some states. The absence of favorable net metering policies or of net metering entirely, or the imposition of new charges that only or disproportionately affect end-users that use net metering would significantly limit demand for our products and could have a material adverse effect on our business, financial condition, results of operations and future growth.

Additionally, as new solar projects are planned and built, as part of the interconnection process, the developers typically are required to pay for any required upgrades to the local distribution lines or to the electric transmission system. In particular areas, as the number of solar projects increases, the costs of these upgrades are likely to increase. This may have the effect of reducing the economic benefits of these projects and may lead to the cancellation of marginal projects. Certainly, federal and state regulatory policies may have an impact on how these interconnection costs are calculated and on the amount of time needed to complete the necessary interconnection studies. There may be risks that federal or state regulators will develop interconnection rules or procedures that are more burdensome than they are today for developers of solar projects.

Changes in other current laws or regulations applicable to us or the imposition of new laws, regulations or policies in the U.S. 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.

Changes in 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.

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 or that of our customers, which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Risks Related to Our Class A Common Stock

The market price of our Class A common stock may decline and may continue to be subject to significant volatility.

The market price of our Class A common stock has, and could be, subject to significant fluctuations. The price of our stock changes in response to fluctuations in our results of operations, the wire insulation shrinkback matter, other factors specific to our Company, and in response to macroeconomic factors as well as factors specific to the solar energy industry and companies in our industry, many of which are beyond our control. As a result, our share price has experienced significant volatility and may not necessarily reflect the

Table of Contents

value of our expected performance, which may prevent investors from being able to sell their Class A common stock at or above their purchase price. Declines in our stock price can also decrease the value of our equity compensation programs, which could make it hard to retain key personnel.

Additionally, the sale of shares of our Class A common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our Class A common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. Furthermore, we have, and in the future, we may also issue securities in connection with investments, acquisitions or capital raising activities, which would dilute our current stockholders and impact the price of our Class A common stock.

Further, the repurchase of our Class A common stock pursuant to the Repurchase Program could affect the price of our Class A common stock and increase its volatility and there can be no assurance that any share repurchases will enhance stockholder value because the stock price of our Class A common stock may decline below the levels at which we effected repurchases. Pursuant to the Repurchase Program announced by the Company on June 11, 2024, we are authorized to repurchase up to $150 million of outstanding shares of our Class A common stock from time to time. As of December 31, 2025, we had repurchased $25 million under the program. We are not obligated to repurchase any additional shares, and the timing, manner, price, and actual amount of future share repurchases will depend on a variety of factors, including stock price, market conditions, other capital management needs and opportunities, and corporate and regulatory considerations. Further, the Repurchase Program may be suspended or discontinued at any time and may reduce the amount of cash we have available, impacting our liquidity.

Because we do not expect to pay any cash distributions or dividends in the foreseeable future, appreciation in the price of our Class A common stock, if any, may be your only source of gain on an investment in our Class A common stock.

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

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could depress the trading price of our Class A 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 to be advantageous. These provisions include: (i) authorizing “blank check” preferred stock that our board of directors could issue to increase the number of outstanding shares to discourage a takeover attempt; (ii) not providing for cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates; (iii) limiting the ability of stockholders to call a special stockholder meeting; (iv) prohibiting stockholders from acting by written consent; (v) 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; (vi) 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 common stock of the Company entitled to vote thereon; (vii) providing that our board of directors is expressly authorized to amend, alter, rescind or repeal our amended and restated bylaws; and (viii) requiring the affirmative vote of holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of Class A 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 amended and restated bylaws.

Table of Contents

Our amended and restated certificate of incorporation also provides that the Court of Chancery of the State of Delaware will be 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 employees.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternate forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by applicable law, be 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 amended and restated certificate of incorporation or our bylaws; any action to interpret, apply, enforce or determine the validity of our amended and restated 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. These forum selection provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable, may discourage such lawsuits against us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers or employees, and could result in increased costs or delays associated with resolving such disputes.

In addition, our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the federal district court for the District of Delaware will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the federal securities laws. It is uncertain whether a court would enforce this provision, and investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Item 7. 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 (“MD&A”) should be read in conjunction with our consolidated 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. For this purpose, any statements contained in this Form 10-K that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, words such as “may,” “will,” “expect,” “believe,” “anticipate,” “estimate” or “continue” or comparable terminology are intended to identify forward-looking statements. 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 Form 10-K captioned “Forward-Looking Statements” and “Risk Factors”. Management’s discussion and analysis relating to the fiscal year ended December 31, 2024 and the applicable year-to-year comparisons to the fiscal year ended December 31, 2023 are not included in this Annual Report on Form 10-K but can be found in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

This MD&A contains the presentation of Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted Earnings per Share, which are not presented in accordance with generally accepted accounting principles in the U.S. (“GAAP”). Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted Earnings per Share are being presented because management believes they provide investors and readers of this Form 10-K with additional insight into our operational performance relative to earlier periods and relative to our competitors. We do not intend Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA,

Table of Contents

Adjusted Net Income, and Adjusted Diluted Earnings per Share to be substitutes for any GAAP financial information. Readers of this Form 10-K should use Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted Earnings per Share only in conjunction with Gross Profit, Net Income, and Net Income Attributable to Shoals Technologies Group, Inc., the most closely comparable GAAP financial measures, as applicable. Reconciliations of Adjusted Gross Profit, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted Earnings per Share to the respective most closely comparable GAAP measure, as well as a calculation of Adjusted Gross Profit Percentage and Adjusted Diluted Weighted Average Shares Outstanding, are provided below, in “—Non-GAAP Financial Measures.”

Overview

Shoals Technologies Group is a leading design-engineering and manufacturer of advanced electrical infrastructure solutions for mission‑critical applications across solar photovoltaic (PV), battery energy storage solutions (BESS), and data center power systems. Our solutions also support original equipment manufacturers (“OEMs”). EBOS encompasses all of the components that are necessary to carry the electric current produced by solar panels or stored by a BESS solution to an inverter and ultimately to the power grid. Since electrical infrastructure is the backbone of a solar or BESS project, our products play a mission-critical role in the quality, safety, reliability, and efficiency of energy projects, which the industry prioritizes over price when selecting EBOS solutions.

We design, manufacture and sell a variety of products used by the solar and battery storage industries, including Solar BLA Solutions; Homeruns, Interconnection and Extension Solutions; Combiners and Re-Combiners; Load Break Disconnects and Transition Solutions; Wireless Performance Monitoring; and BESS. We refer to complete EBOS solutions that use products manufactured by us, typically in connection with the design and specification of an entire EBOS system, as “system solutions”. When we sell a system solution, we work with our customers to design, specify and engineer their system solution to provide a complete customized EBOS solution consisting of individualized products that maximizes reliability and energy production while minimizing cost. We also provide technical support during installation and the transition to operations and maintenance. We refer to individual, often custom and proprietary, products we sell as “components”. We believe our system solutions are unique in our industry because they integrate design and engineering support, proprietary components and innovative installation methods into a single offering that would otherwise be challenging for a customer to obtain from a single provider or at all.

Traditionally, and for the year ended December 31, 2025, we primarily sold our EBOS solutions and OEM components to customers in the United States, while also fulfilling orders for international utility-scale solar projects. Specifically, we primarily sold to engineering, procurement and construction firms (“EPCs”) for use in large solar and BESS projects designed to generate electricity and feed it directly into the electric grid, typically with a generation capacity of 1 megawatt or greater. These EPCs work with owners and developers of solar assets to build energy infrastructure projects. However, given the mission-critical nature of EBOS (as further described below), the decision to use our products typically involves input from both the EPC and the owner/developer of the energy infrastructure energy project.

We have a focus in two end-markets: (1) clean, grid connected energy and (2) data center + mission-critical electrical infrastructure. This market diversification seeks to capitalize on the growing global demand for energy and the need to accelerate electrification.

We derived 78.7% of our revenue from the sale of system solutions for the year ended December 31, 2025. As of December 31, 2025, we had $747.6 million of backlog and awarded orders. Backlog of $326.2 million represents signed purchase orders or contractual minimum purchase commitments with take-or-pay provisions and awarded orders of $421.4 million are orders we are in the process of documenting a contract for but for which a contract has not yet been signed. As of December 31, 2025, we believe approximately $326.2 million of backlog and $277.3 million of awarded orders have delivery dates in 2026. The remaining $144.1 million have planned delivery dates beyond 2026. Additionally, we believe more than 12% of

Table of Contents

our December 31, 2025 backlog and awarded orders relate to international projects. As of December 31, 2025, backlog and awarded orders increased by 17.8% relative to December 31, 2024 and increased by 3.7% relative to September 30, 2025.

Elimination of Up-C Structure and Entity Simplification

In the first quarter of 2023, we simplified our corporate structure by, among other things, eliminating the umbrella-partnership C corporation structure (“Up-C structure”) that was in place since its January 29, 2021 initial public offering (“IPO”). Following a secondary offering of shares of Class A common stock by certain selling stockholders in March 2023, all the holders of limited liability interests of Shoals Parent LLC (“LLC Interests”), our former operating subsidiary, exchanged all the LLC Interests and corresponding shares of Class B common stock of the Company beneficially owned by them into shares of Class A common stock of the Company. As a result, upon effectiveness of such exchanges, all of the LLC Interests in Shoals Parent LLC were held by the Company, no other holders owned LLC Interests and no Class B common stock was or is outstanding.

Following the elimination of the Up-C structure, effective December 31, 2023, the Company consummated an internal reorganization transaction whereby certain of the Company’s wholly-owned subsidiaries merged with and into other subsidiaries. As part of this reorganization, Shoals Parent LLC merged with and into Shoals Intermediate Parent, with Shoals Intermediate Parent as the surviving corporation.

Trends and Uncertainties

Trade Regulation and Import Tariffs

Our business activities are subject to numerous laws and regulations in the jurisdictions in which we operate. Particularly, our exports and imports are subject to complex trade and customs laws, tax requirements and tariffs set by governments through mutual agreements or unilateral actions. Changes in tax policies or trade regulations, the disallowance of tax deductions on imported merchandise, or the imposition of new tariffs on imported products, including reciprocal tariffs, could have an adverse effect on our business and results of operations.

Beginning in March 2025, the current U.S. presidential administration (the “Administration”) unveiled broad actions related to tariffs with global trading partners. Subsequently, the Administration has imposed a series of significant tariffs, including a 10% tariff on most imports from other trading partners, as well as additional reciprocal tariffs on specific countries. Administration activity related to changes in tariff percentages and qualifying products, including active negotiations with trading partners and internal trade policy development, is ongoing. Future changes in tariff policy, scope, or duration remain highly uncertain and may occur with little advance notice. The Administration’s imposition of tariffs has led to retaliatory tariffs and tariff countermeasures, and the Administration and U.S. trading partners have threatened further restrictions on trade.

As a result, the global trade environment has experienced extreme uncertainty and volatility and is rapidly evolving. In recent years, we have expanded our domestic capabilities, supply chain resiliency, and manufacturing capacity, which helps offset some of the volatility we face due to trade policies and regulations. However, these actions may not fully mitigate the effects of current or future tariff policies.

In 2025, the impacts of tariffs have caused a deterioration on our gross margins through our direct payment of tariffs and secondary tariff costs passed to us rising prices from suppliers. The future implementation, scope, and modification of tariffs is still uncertain. Any significant new tariffs or the threat thereof, which may last for an indefinite period of time, may make it more difficult for us to source raw materials

Table of Contents

and could result in increased prices for certain of our raw materials including steel, copper and aluminum. Retaliatory tariffs imposed by trading partners could impact the export of our manufactured projects and cause our customers to seek alternatives. The implementation of these proposed tariffs, any future increases in existing tariff rates, additional tariffs on other goods, or further retaliatory actions from other governments, or the threat thereof, may result in higher costs for us, and there can be no assurance we will be able to pass on any of the increases in raw material costs directly resulting from the tariffs to our customers. Such actions may also result in more difficulty or the inability to obtain needed materials.

On February 20, 2026, the U.S. Supreme Court invalidated the Administration's tariff measures after concluding that the International Emergency Economic Powers Act did not authorize their imposition. It is uncertain how future repercussions of the ruling and other changes in trade policy would impact our operations, supply chain, and cash flow.

Beyond the most recent tariffs, over the past few years, escalating trade tensions between the United States and China and other jurisdictions led to increased tariffs and trade restrictions, including tariffs applicable to some of our products. We have been assessing and monitoring the potential impact of tariffs on our supply chain and proactively seeking to mitigate the impact such may have on our operations, including working on alternative sourcing strategies and preparing our trade partners to absorb potential increases in their costs due to tariffs. However, we cannot be certain that we would not experience negative effects in the future, particularly given the Administration’s positions concerning trade and tariffs and the fluctuating nature of such actions to date.

We also continue to monitor the condition of our supply chain and evaluate our procurement strategy to reduce any negative impact on our business, financial condition, and results of operations. During the period ended December 31, 2025, we continued to monitor and optimize our inventory levels in preparation for upcoming production demands.

Federal, state, local and foreign government bodies provide incentives to owners, end users, distributors and manufacturers of solar energy systems to promote the development of solar electricity. The range and duration of these incentives varies widely by geographic market.

The 2022 Inflation Reduction Act (“IRA”) in the U.S. made significant changes to the U.S. tax code to incentivize the development and use of solar-generated electricity to meet the country’s growing demand for power. The IRA offered tax incentives to companies who provide goods connected to the development and use of solar energy. The IRA allowed U.S. taxpayers making capital investments in solar projects to claim certain Investment Tax Credits (“TC”) for the installation of these solar projects. The IRA also generally allowed U.S. taxpayers to elect to receive a production tax credit (“PTC”) in lieu of the TC for qualified solar facilities if the construction began before January 1, 2025, among other requirements.

In 2025, H.R. 1, the One Big Beautiful Bill Act, was enacted into law. H.R. 1 significantly modifies certain energy tax provisions aforementioned in the IRA. Changes to the IRA made by H.R. 1 include an accelerated phaseout or termination of the PTC and TC for solar projects placed in service after 2027. There are also rules related to foreign entities of concern that make any solar projects owned or controlled by a prohibited foreign entity ineligible for certain tax credits. The removal of the incentives that drive demand for solar energy production could reduce the financial attractiveness of solar projects, leading to decreased demand for our products. Additionally, the uncertainty surrounding the future of these incentives could cause delays in project financing and execution, further impacting our sales volume and growth rate.

The Solar Market

The domestic utility scale solar market has experienced volatility that has had an impact on our business. Industry trends are impacted by a variety of factors, including: permitting issues; supply chain

Table of Contents

disruptions; labor availability; project financing; anti-dumping and countervailing duties; interconnection complications; and uncertainty regarding changes in public policy and the U.S. trade environment. Amidst the volatility, the U.S. solar industry has shown demonstrated levels of growth in 2025, with recorded expansion in new solar module manufacturing capacity according to the Solar Energy Industries Association. As a result, we believe the industry is poised for continued growth across both our core and new markets, driven by the continued and increasing need for energy around the world.

We will continue to navigate the uncertainties in our industry, including those relating to project delays, as well as strategic pricing actions, volume discounts, and impacts to customer mix in our key markets.

Other Macroeconomic Pressures

Global inflationary pressures persisted during 2025; however, the impact of inflation remains uncertain in the future. Interest rates have remained generally higher when compared to historical rates, causing the interest rates associated with our Senior Secured Credit Agreement to be generally higher; however, interest rates did decline from their historically high levels during the course of 2024. Should interest rates rise, when combined with the implications of higher government deficits and debt, evolving monetary policy, political instability, and volatility and uncertainty in global trade, the Company’s costs for accessing capital are uncertain and may rise during our forecasted period.

Our ability to obtain the raw materials required to manufacture our components and system solutions from domestic and international suppliers, as well as our ability to secure inbound logistics to and from our facilities, remained challenging during 2025, complicated by volatility in government policies and regulation concerning trade and ongoing political conflict. While the Company does not directly source a significant amount of raw materials from Europe, the Russia-Ukraine war has reduced the availability of certain materials that can be sourced in Europe and, as a result, increased global logistics costs for the procurement of some inputs and materials used in our products. We expect these trends to persist as challenges and conflicts remain in 2026.

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 EBOS solutions and components for solar, BESS, and OEM offerings. Our customers include EPCs, utilities, solar developers, independent power producers, and solar module manufacturers. We derive the majority of our revenue from selling system solutions. When we sell a system solution, 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 system solutions can vary from one to three months whereas manufacturing typically requires a shorter time frame. Contracts for system solutions can range in value from several hundred thousand to several million dollars.

Our revenue is affected by changes in the price, volume and mix of system solutions and components purchased by our customers. The price and volume of our system solutions and components is driven by the demand for our energy infrastructure system solutions and components, volume based discounts and rebate incentives, changes in product mix, geographic mix of our customers, strength of competitors’ product offerings, and availability of government incentives to the end-users of our products.

Our revenue growth is dependent on continued growth in the amount of projects to support energy infrastructure constructed each year and our ability to increase our share of demand in the geographies where we currently compete and plan to compete in the future, as well as our ability to continue to develop and

Table of Contents

commercialize new and innovative products that address the changing technology and performance requirements of our customers.

Cost of Revenue and Gross Profit

Cost of revenue consists primarily of system solutions and components costs, including purchased raw materials, as well as costs related to importing and tariffs, shipping, customer support, product warranty, personnel and depreciation of manufacturing and testing equipment. Personnel costs in cost of revenue include both direct labor costs as well as costs attributable to any individuals whose activities relate to the transformation of raw materials or component parts into finished goods or the transportation of materials to the customer. Our product costs are affected by the underlying cost of raw materials, including copper and aluminum; component costs, including fuses, resin, enclosures, and cable; technological innovation; economies of scale resulting in lower component costs; and improvements in production processes and automation. We do not currently hedge against changes in the price of raw materials. Some of these costs, primarily indirect personnel and depreciation of manufacturing and testing equipment, are not directly affected by sales volume. Gross profit may vary from year to year and is primarily affected by our sales volume, product prices, product costs, product mix, customer mix, geographical mix, shipping method and warranty expense.

Operating Expenses

Operating expenses consist of general and administrative expenses as well as depreciation and amortization expense. Personnel-related costs are the most significant component of our operating expenses and include salaries, equity-based compensation, benefits, payroll taxes and commissions. The number of full-time employees in our general and administrative departments increased from 185 to 199 from December 31, 2024 to December 31, 2025, and we expect to hire new employees in the future to support our growth. The timing of these additional hires could materially affect our operating expenses in any particular period, both in absolute dollars and as a percentage of revenue.

General and Administrative Expenses

General and administrative expenses consist primarily of legal and professional fees, salaries, equity-based compensation expense, employee benefits and payroll taxes related to our executives, and our sales, finance, human resources, information technology, engineering and legal organizations, travel expenses, facilities costs, marketing expenses, insurance, bad debt expense and fees for professional services. Professional services consist of audit, tax, accounting, legal, internal controls, information technology, investor relations and other costs. We expect to increase our sales and marketing personnel as we expand into new geographic markets. Substantially all of our sales are currently in the U.S. We currently have a sales presence in the U.S., Asia-Pacific, Europe, Latin America, and Africa. We intend to grow our sales presence and marketing efforts in current geographic markets and expand to additional countries in the future.

Depreciation

Depreciation in our operating expenses consists of costs associated with property, plant and equipment (“PP&E”) not used in manufacturing our products. We expect that as we increase both our revenue and the number of our general and administrative personnel, we will invest in additional PP&E to support our growth resulting in additional depreciation expense.

Amortization

Amortization of intangibles consists of amortization of customer relationships, developed technology, trade names, backlog and noncompete agreements over their expected period of use.

Non-operating Expenses

Interest Expense

Table of Contents

Interest expense consists of interest and other charges paid in connection with our Senior Secured Credit Agreement.

Interest income

Interest income is related to interest on bank deposits.

Gain on sale of assets

Gain on sale of assets represents consideration received in excess of the net book value of assets sold.

Foreign currency (loss) gain, net

Foreign currency gains and losses arise from the remeasurement of transactions in a currency other than the function currency of the Company based on exchange rate fluctuations.

Income Tax Expense

Shoals Technologies Group, Inc. is subject to U.S. federal and state income tax in multiple jurisdictions. Prior to the July 1, 2023 contribution described in Note 16 - Income Taxes in our consolidated financial statements included in this Annual Report on Form 10-K, Shoals Parent LLC was a pass-through entity for federal income tax purposes but incurred income tax in certain state jurisdictions. On July 1, 2023, the Company contributed 100% of its LLC Interests in Shoals Parent LLC to its wholly-owned subsidiary, Shoals Intermediate Parent, and following the contribution, Shoals Parent LLC became a disregarded single member limited liability company, eliminating the Up-C structure.

Revenue

Revenue increased by $76.1 million, or 19%, for the year ended December 31, 2025 as compared to the year ended December 31, 2024, driven by increased sales volumes from higher demand of products to meet utility scale solar project demands.

Cost of Revenue and Gross Profit

Cost of revenue increased by $51.6 million, or 20%, for the year ended December 31, 2025 as compared to the year ended December 31, 2024, driven by the increase in revenue. Gross profit as a percentage of revenue was 35.0% for the year ended December 31, 2025 as compared to 35.6% for the year ended December 31, 2024. This change in gross margin was due to a reduced amount of wire insulation shrinkback expenses in the current year compared to the prior year, offset by increased material costs, tariffs, non-recurring operational charges, competitive dynamics, volume discounts, and product mix in our key markets, and a reduction in leverage on fixed costs.

Operating Expenses

General and Administrative

General and administrative expenses increased $19.3 million, or 23%, for the year ended December 31, 2025 as compared to the year ended December 31, 2024. General and administrative expenses increased primarily due to higher legal and professional costs of $15.7 million. These include expenses related to intellectual property litigation that rose from $6.0 million in 2024 to $9.1 million in 2025, wire‑insulation shrinkback litigation increased from $7.2 million to $18.3 million, and stockholder litigation increased from $0.9 million to $2.5 million. Payroll and employee‑related expenses also grew by $1.3 million.

Depreciation and Amortization

Depreciation and amortization expense within operating expenses increased by less than $0.1 million or 0.1%, for the year ended December 31, 2025 as compared to the year ended December 31, 2024. The stability in the balance was due to consistent amortization of intangible assets.

Interest Expense

Interest expense decreased by $3.8 million or 28%, for the year ended December 31, 2025 as compared to the year ended December 31, 2024. This decrease is explained by prior year activity related to our voluntary prepayments on the Term Loan Facility and amendment of the Senior Secured Credit Agreement. Due to the prepayments in 2024 and amendment, the Company wrote off a liability of $2.5 million of unamortized deferred interest, along with an asset of $2.3 million of unamortized deferred financing costs. This is offset by a higher weighted average outstanding balance in 2025 as compared to 2024 yielding higher quarterly interest payments.

Interest Income

Interest income decreased from the prior year by $0.2 million. This is due to a lower weighted average balance held in our interest bearing accounts for cash and cash equivalents as compared to the prior year.

Gain on sale of assets

Gain on sale of assets increased $1.8 million from the previous period due to the sale of owned land and building assets to consolidate operations into new facilities and the disposal of other manufacturing equipment.

Income Tax Expense

Table of Contents

Income tax expense was $14.9 million for the year ended December 31, 2025 as compared to income tax expense of $13.7 million for the year ended December 31, 2024. Our effective income tax rate for the year ended December 31, 2025 and 2024 was 30.8% and 36.3%, respectively. The effective income tax rate decreased compared to the prior year, due to a reduced impact from valuation allowance adjustments. In the prior year, the Company established state-specific valuation allowances, which increased income tax expense. In the current year, the valuation allowance impact was substantially lower, resulting in a decreased effective income tax rate.

Non-GAAP Financial Measures

Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted Earnings per Share (“EPS”)

We define Adjusted Gross Profit as gross profit plus wire insulation shrinkback expenses. We define Adjusted Gross Profit Percentage as Adjusted Gross Profit divided by revenue. We define Adjusted EBITDA as net income plus/(minus) (i) interest expense, (ii) interest income (iii) income tax expense, (iv) depreciation expense, (v) amortization of intangibles, (vi) equity-based compensation, (vii) gain/loss on sale of assets, (viii) wire insulation shrinkback expenses, (ix) wire insulation shrinkback litigation expenses, and (x) plant optimization expenses. We define Adjusted Net Income as net income attributable to Shoals Technologies Group, Inc. plus (i) net income impact from assumed exchange of Class B common stock to Class A common stock as of the beginning of the earliest period presented, (ii) adjustment to the provision for income tax, (iii) amortization of intangibles, (iv) amortization / write-off of deferred financing costs, (v) equity-based compensation, (vi) gain/loss on sale of assets, (vii) wire insulation shrinkback expenses, (viii) wire insulation shrinkback litigation expenses, and (ix) plant optimization expenses, all net of applicable income taxes. We define Adjusted Diluted EPS as Adjusted Net Income divided by the diluted weighted average shares of Class A common stock outstanding for the applicable period, which assumes the exchange of all outstanding Class B common stock for Class A common stock as of the beginning of the earliest period presented.

Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS are intended as supplemental measures of performance that are neither required by, nor presented in accordance with, GAAP. We present Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS because we believe they assist investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. In addition, we use Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS: (i) as factors in evaluating management’s performance when determining incentive compensation, as applicable; (ii) to evaluate the effectiveness of our business strategies; and (iii) because our credit agreement uses measures similar to Adjusted EBITDA, Adjusted Net Income and Adjusted Diluted EPS to measure our compliance with certain covenants.

Among other limitations, Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS do not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments; do not reflect the impact of certain cash charges resulting from matters we consider not to be indicative of our ongoing operations; and may be calculated by other companies in our industry differently than we do or not at all, which may limit their usefulness as comparative measures.

Because of these limitations, Adjusted Gross Profit, Adjusted Gross Profit Percentage, Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS should not be considered in isolation or as substitutes for performance measures calculated in accordance with GAAP. You should review the reconciliation of gross profit to Adjusted Gross Profit and Adjusted Gross Profit Percentage, net income to

(a) For the year ended December 31, 2025 represents no wire insulation shrinkback warranty expenses related to the identification, repair and replacement of a subset of wire harnesses presenting unacceptable levels of wire insulation shrinkback, nor any inventory write-downs of wire in connection with wire insulation shrinkback. For the year ended December 31, 2024 represents (i) $13.3 million of wire insulation shrinkback warranty expenses related to the identification, repair and replacement of a subset of wire harnesses presenting unacceptable levels of wire insulation shrinkback, and (ii) $0.5 million of inventory write-downs of wire in connection with wire insulation shrinkback. We consider expenses incurred in connection with the identification, repair and replacement of the impacted wire harnesses as well as the write-down of related inventory distinct from normal, ongoing service identification, repair and replacement expenses that would be reflected under ongoing warranty expenses within the operation of our business and normal write-downs of inventory, which we do not exclude from our non-GAAP measures. In the future, we also intend to exclude from our non-GAAP measures the benefit of liability releases, if any. We believe excluding expenses from these discrete liability events provides investors with a better view of the operating performance of our business and allows for comparability through periods. See Note 8 - Warranty Liability, in our consolidated financial statements included in this Annual Report on Form 10-K for more information.

(b) For the year ended December 31, 2025, represents $18.3 million of expenses incurred in connection with the lawsuit initiated by the Company against the supplier of the defective wire.

We consider this litigation distinct from ordinary course legal matters given the expected magnitude of the expenses, the nature of the allegations in the Company’s complaint, the amount of damages sought, and the impact of the matter underlying the litigation on the Company’s financial results. In the future, we also intend to exclude from our non-GAAP measures the benefit of recovery, if any. We believe excluding expenses from these discrete litigation events provides investors with a better view of the operating performance of our business and allows for comparability through periods.

Liquidity and Capital Resources

We finance our operations primarily with operating cash flows and borrowings from our Revolving Credit Facility. Our ability to generate positive cash flow from operations is dependent on our gross profits 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 and availability under our Revolving Credit Facility will be sufficient to meet our near and long-term future cash needs.

We generated cash from operating activities of $17.1 million during the year ended December 31, 2025, as compared to cash provided by operating activities of $80.4 million and $92.0 million, respectively, during the years ended December 31, 2024 and 2023. As of December 31, 2025, our cash and cash equivalents were $7.3 million, a decrease from $23.5 million as of December 31, 2024. As of December 31, 2025 we had

Table of Contents

outstanding borrowings of $136.8 million, a decrease from $141.8 million as of December 31, 2024. As of December 31, 2025 we also had $60.5 million available for additional borrowings under our $200.0 million Revolving Credit Facility.

On December 27, 2023 and January 19, 2024, we used proceeds from the Revolving Credit Facility and cash on hand to make $50.0 million and $100.0 million, respectively, voluntary prepayments of outstanding borrowings under the Term Loan Facility. Following the amendment to the Senior Secured Credit Agreement on March 19, 2024, which, among other things, increased the amount available for borrowing under the Revolving Credit Facility from $150.0 million to $200.0 million, we made a $43.8 million voluntary prepayment of all the outstanding term loans under the Senior Secured Credit Agreement, thereby terminating the Term Loan Facility.

On June 11, 2024, the Company announced a share repurchase program (the “Repurchase Program”) authorizing the repurchase of up to $150.0 million of the Company’s Class A common stock, with an estimated completion date of December 31, 2025. Under the Repurchase Program, the Company is authorized to repurchase shares of Class A common stock through open market purchases, privately-negotiated transactions, accelerated share repurchases or otherwise in accordance with applicable federal securities laws, including through Rule 10b5-1 trading plans and under Rule 10b-18 of the Exchange Act.

In connection with the Repurchase Program, on June 11, 2024, the Company entered into an accelerated stock repurchase (“ASR”) with Jefferies LLC to repurchase $25.0 million of the Company’s Class A common stock. Under the terms of the ASR, the Company paid $25.0 million to Jefferies LLC on June 12, 2024, and received a total of 3,908,387 shares of the Company’s Class A common stock upon final settlement. Final settlement was based on a repurchase price of $6.40 per share, which was based on the average of the daily volume weighted average price per share of the Company’s Class A common stock during the term of the ASR, less a discount.

Our capital expenditures primarily relate to purchases of property, plant, and equipment to support manufacturing operations and growth initiatives. In 2025, we had capital expenditures of $33.0 million. In 2026, we expect capital expenditures between $20.0 million to $30.0 million, subject to other strategic uses of capital and the evolution of operating cash flows and the working capital position throughout the year. We believe our cash flow from operations will generally be sufficient to fund these expenditures.

In 2025, we also used approximately $41.0 million of cash to pay for expenses related to the identification, repair and replacement of the wire harnesses impacted in connection with the wire insulation shrinkback matter. We expect to continue spending significant amounts of cash in connection thereof. For more information, see Note 8 - Warranty Liability in our consolidated financial statements included in this Annual Report on Form 10-K for more information.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with GAAP. The preparation of consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by our management. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as

Table of Contents

these policies relate to the more significant areas involving management’s judgments and estimates. Critical accounting policies and estimates are those that we consider the most important to the portrayal of our financial condition and results of operations because they require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain.

Revenue Recognition

We primarily recognize revenue over time as a result of the continuous transfer of control of our product to the customer using the output method based on units manufactured. This continuous transfer of control to the customer is supported by clauses in the contracts that provide right to payment of the transaction price associated with work performed to date on products that do not have an alternative use. We believe that recognizing revenue using the output method based on units manufactured best depicts the extent of transfer of control to the customer. If revenue were recognized at a point in time rather than over time, then for the year ended December 31, 2025, net income would be $0.4 million higher, and EPS - basic and diluted would increase by $0.01.

In certain instances the promised goods do have an alternative use. In these instances, we recognize revenue when the customer obtains control of the product. Contracts of this nature typically include customer acceptance clauses, which results in revenue recognition occurring upon customer acceptance.

Depending on the size of project, the manufacturing process generally takes from less than one week to four months to complete production. The accounting for each contract involves a judgmental process of estimating total sales, costs, and profit for each performance obligation. Cost of revenue is recognized based on the unit of production. The amount reported as revenue is determined by adding a proportionate amount of the estimated profit to the amount reported as cost of revenue.

We have elected to adopt certain practical expedients and exemptions as allowed under the revenue recognition guidance such as (i) recording sales commissions as incurred because the amortization period is less than one year, (ii) excluding any collected sales tax amounts from the calculation of revenue, and (iii) accounting for shipping and handling activities that are incurred after the customer has obtained control of the product as fulfillment costs rather than a separate service provided to the customer for which consideration would need to be allocated.

Equity-Based Compensation

2021 Long-term Incentive Plan

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 closing market price of the Company's common stock on the day prior to the grant date. Equity-based compensation expense related to performance stock units is recognized if it is probable that the performance conditions will be satisfied. 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, including those units with graded vesting. However, the amount of equity-based compensation at any date is at least equal to the portion of the grant date fair value of the award that is vested.

Income Taxes

We record valuation allowances against our deferred tax assets when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In making such determination, we consider all available evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and results of operations. We routinely evaluate the realizability of our deferred tax assets by assessing the likelihood that our deferred tax assets will be recovered based on all available positive and

Table of Contents

negative evidence. Estimating future taxable income is inherently uncertain and requires judgment. In projecting future taxable income, we consider our historical results and incorporate certain assumptions, including revenue growth and operating margins, among others. As of December 31, 2025, we had $438.0 million of deferred tax assets, net of a $3.0 million valuation allowance related to land, other non-amortizable intangibles, and state tax attributes for net operating loss carryforwards and goodwill amortization. Other than these valuation allowances, we expect to realize future tax benefits related to the utilization of these assets. If we determine in the future that we will not be able to fully utilize all or part of these deferred tax assets, we would increase our valuation allowance through earnings in the period the determination was made, which would have an adverse effect on our results of operations and earnings in future periods.

Product Warranty

General Warranty

The Company offers an assurance type warranty for its products against manufacturer defects and does not contain a service element. For these assurance type warranties, a provision for estimated future costs related to warranty expense is recorded when they are probable and reasonably estimable. 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 an immature product line, the estimate is based on comparable product lines. Specific reserves are established once an issue is identified with the amounts for such reserves based on the estimated cost of correction. These estimates are re-evaluated on an ongoing basis using best-available information and revisions to estimates are made as necessary. These estimates are inherently uncertain given our relatively short history of sales, and actual results that differ from our assumptions and judgments could have a material adverse effect on our business, financial condition and results of operations.

Wire Insulation Shrinkback Warranty

The Company was notified by certain customers that a subset of wire harnesses used in its EBOS solutions has presented unacceptable levels of contraction of wire insulation (“wire insulation shrinkback”). Based upon the Company’s assessment, the Company currently believes the wire insulation shrinkback is related to defective wire manufactured by Prysmian Cables and Systems USA, LLC (“Prysmian”). Based on the Company’s continued analysis of information available as of the date of this Annual Report, the Company determined that a potential loss was both probable and reasonably estimable. For the year ended December 31, 2023, the Company disclosed an initial range of potential loss from $59.7 million to $184.9 million. During the year ended December 31, 2024, the Company determined it was appropriate to adjust the range of estimates previously provided based on additional information obtained. The low-end of the estimated range increased to $73.0 million and the high-end decreased to $160.0 million.

In accordance with ASC 450, Contingencies , the Company believes the potential estimated loss for this matter is $73.0 million, which represents the best estimate of the potential loss as of December 31, 2025, of which $69.7 million has been incurred to date. As of December 31, 2025 and December 31, 2024, our recorded warranty liability related to this matter was $3.3 million and $39.9 million, respectively. It is reasonably possible that our liability could exceed the amount recorded, including due to additional reports of wire insulation shrinkback at previously affected and reported solar projects or at projects not previously reported or otherwise identified. Any excess amounts remain uncertain.

The Company recorded total warranty expense related to this matter of zero, $13.3 million, and $59.2 million respectively, during the years ended December 31, 2025, 2024 and 2023.

The estimated loss, as revised, continues to be based on several assumptions, including estimated failure rates, future notification of impacted harnesses, the potential magnitude of engineering, procurement and construction firm’s labor cost to identify and perform the repair and replacement of impacted harnesses, materials replacement cost, planned remediation method, and inspection costs. While our wire insulation shrinkback warranty liability represents our best estimate of expected losses, the Company will monitor future

Table of Contents

activity to best estimate potential losses. The Company has increased, and may further increase, its estimated warranty liability from its current estimate based on available information, including future remediation efforts and the scope of future replacements, if any. Such increase may be material. The Company does not maintain insurance for product warranty issues and has commenced a lawsuit against Prysmian, as discussed in more detail under Wire Insulation Shrinkback Litigation section of Note 15 - Commitments and Contingencies. Because the lawsuit against Prysmian is ongoing, potential recovery from Prysmian is not considered probable as defined in ASC 450, Contingencies , and has not been considered in our estimate of the warranty liability as of December 31, 2025.

As of December 31, 2025, a 20% increase in projects that would require standard remediation work would have resulted in an increase in our recorded liability of $1.1 million. Additionally, changes to the planned remediation method could also have a material impact on the warranty liability.
