ITEM 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OFOPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the financial statements and related notes thereto, included in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report.

Overview

Energy Focus, Inc. engages primarily in the design, development, manufacturing, marketing and sale of energy-efficient lighting systems and controls. We develop, market and sell high quality light-emitting diode (“LED”) lighting and controls products in the commercial market and military maritime market (“MMM”). Our mission is to enable our customers to run their facilities with greater energy efficiency, productivity, and human health and wellness through advanced LED retrofit solutions. Our goal is to be a market leader for the most demanding applications where performance, quality, value, environmental impact and health are considered paramount. We specialize in energy efficient LED lighting retrofit product, replacing fluorescent, high-intensity discharge lighting and other types of lamps in institutional buildings for primarily indoor lighting applications with our innovative, high-quality commercial and military-grade tubular LED (“TLED”) products, as well as other LED and lighting control products for commercial and consumer applications. We are also evaluating adjacent technologies, including Gallium Nitride (“GaN”) based power supplies and additional market opportunities for energy solution products that support sustainability in our existing channels.

The LED lighting industry has changed dramatically over the past several years due to increasing competition and price erosion. We have been experiencing these industry forces in both our military and commercial business since 2016, when we once commanded significant price premiums for our flicker-free TLEDs with industry leading warranties. In more recent years, we have focused on redesigning our products for lower costs and consolidated our supply chain for stronger purchasing power in an effort to price our products more competitively while not impacting the performance and quality. Despite these efforts, our legacy products continue to face extreme price competition and a convergence of product functionality in the marketplace, and we have shifted to diversifying our supply chain in an effort to increase value and remain competitive. These trends are not unique to Energy Focus as evidenced by the increasing number of industry peers facing challenges, exiting LED lighting, selling assets and even going out of business.

In addition to continuously pursuing cost reductions, our strategy to combat these trends is to innovate both our technology and product offerings with differentiated products and solutions that offer greater, distinct value. Specific examples of these products we have developed include the RedCap®, our patented emergency backup battery integrated TLED, as well as our robust MMM product offering. The Company has enhanced the performance of our RedCap® product providing a more user- friendly experience. We continue to evaluate our sales strategy and believe our go-to-market strategy that focuses more on direct-sales marketing, selectively expanding our channel partner network to cover territories across the country, and listening to the voice of the customer will lead to better and more impactful product development efforts that we believe will eventually translate into larger addressable markets and greater sales growth for us.

Since 2023, the Company has continued to make significant cost cutting efforts to address operational expenses while maintaining customer satisfaction and delivering goods on-time. Investments into Energy Focus have contributed to the ability of the Company to continue to not only provide quality products and services, but to both expand and rationalize product offerings.

It is our belief that the continued dramatic rightsizing efforts undertaken in 2023 and 2024, along with reorganization of the sales team and ongoing development of innovative, high-value products and an expanded distribution network, will over time result in improved sales and bottom-line performance for the Company.

We have taken steps to strengthen our financial structure through capital increases and cost reduction measures. As a result, we have fully eliminated all external high-interest debt, which we believe has improved our financial position. Our business expansion plans are supported by financial strategies that we expect will provide funding for our planned growth initiatives, although there can be no assurance that such funding will be adequate. During 2024, our MMM business faced ongoing challenges due to delays in government funding and the timing of U.S. Navy awards. Several anticipated projects encountered repeated postponements, further complicated by the long sales cycles typical in this sector. The timeline from bid submission to order placement often exceeds six months, and many MMM products are built-to-order, resulting in extended lead times before revenue recognition. To mitigate this volatility, we continue to actively pursue new opportunities with the U.S. Navy and other government sectors. We have undertaken efforts to reduce costs and improve production efficiencies in MMM product lines which we believe have contributed to our competitiveness, and may have helped us secure new contracts and expand our sales pipeline in the latter half of 2024.

Table of Contents

We intend to focus on developing our commercial product offerings, including planned new product lines such as Energy Storage Systems (ESS), GaN Power Supplies, and UPS systems for data centers, while continuing to leverage the stability and opportunities within our MMM business. In 2024, we conducted a comprehensive review of our commercial pricing strategy and reassessed key partnerships within the energy related market. These strategic adjustments have improved our market position, offering a more competitive pricing structure and a stronger value proposition for our customers. We believe that these initiatives, if successfully implemented, and if our financial position continues to improve, may contribute to growth across both our MMM and commercial business sectors, although there can be no assurance that such growth will occur.

Meanwhile, we continue to seek additional external funding alternatives and sources to support our growth strategies, plans and initiatives. The strategic investments in 2023 and 2024 by Sander Electronics, Inc. (“Sander”), a shareholder of the Company, contributed meaningful external capital, as well as presented synergistic opportunities to improve and diversify our supply chain and product offerings.

Despite continuing progress on cost reduction throughout 2023 and 2024, the Company’s results reflect the challenges due to long and unpredictable sales cycles, unexpected delays in MMM and commercial customer retrofit budgets and project starts, and supply chain issues. There has also been continuing aggressive price competition in the lighting industry. We continue to incur losses and we have a substantial accumulated deficit, which continues to raise substantial doubt about our ability to continue as a going concern at December 31, 2024.

Our Business Strategy

Demand-oriented Approach

In order to deepen our relationships with customers, we are in the process of re-establishing our service model, aiming to provide richer and more targeted customer service. We believe that by increasing opportunities for interaction with our customers, we can better understand their needs, thereby enhancing their loyalty to our brand.

To ensure that EFOI’s products, pricing, and customer service lifecycle are better aligned, we are building a comprehensive value model to ensure consistency in the products and services we provide throughout the customer journey. We have begun an in-depth analysis of our current and past top 10 customers over the last five years to identify the core factors that make them loyal customers. By analyzing this data, we hope to reveal the key elements that enhance customer stickiness, providing them with more reasons and value to stay with us. In particular, we are actively focusing on customers with high loyalty to better meet their needs. This is not only an acknowledgment of our products but also a validation of the quality of our service.

Supply-oriented Approach

EFOI is committed to adopting three main sustainable economy strategies: “Green Supply Chain”, “Green Product”, and “Green Manufacturing”, aiming to promote sustainability throughout the entire value chain. The Company is working closely with its supply chain partners to optimize recycling mechanisms and strengthen packaging design, integrating sustainable economy principles into the core of supply chain management.

Guided by the vision of “transcending traditional corporate social responsibility and creating shared value”, EFOI’s team is focusing on stakeholders, aiming to achieve a “dual profit engine” effect by combining financial performance and Environmental, Social, and Governance (ESG) practices. This strategy not only aligns with the Company’s responsibility and sustainability goals but is also expected to enhance overall performance and market competitiveness. EFOI's operational team's new strategy focuses on integrating environmental and economic benefits, aiming to create a win-win situation that benefits the company, society, and the environment.

Under the premise of a similar industrial environment and familiar relationships, our professional skills complement those of our supply chain partners. We believe this foundation of cooperation may enable us to pursue common goals of cost reduction, profit sharing, and exploring new business opportunities. This not only strengthens our cooperative relationship but also lays a solid foundation for our joint efforts towards a better future.

Financial-oriented Approach

The Company applies strategic financial management in the below perspective.

Control and Monitoring of Assets and Liabilities

•Assets: Regularly evaluate all assets, especially inventory, to ensure they remain in optimal condition in terms of value and performance. Minimize or mitigate the impact of inefficient and aging assets, focusing on assets with high efficiency and return.

28

Table of Contents

•Liabilities: Ensure a robust liability structure, optimize the cost of liabilities, and seek lower interest rates and more favorable repayment terms. Regularly review the liability situation to ensure the company’s level of liabilities remains within a safe range.

Structured Profitability

•Revenue Growth: Develop diversified revenue streams, reduce dependency on single business or market, continuously optimize products and services, and enhance market competitiveness.

•Cost Control: Strictly control operating costs, seek opportunities to reduce costs, and ensure the efficient use of resources to optimize operations.

•Cash Flow Management: Establish a sound accounts receivable and payable management system to ensure timely collection of receivables and reasonable arrangement of payments. Maintain sufficient cash reserves to cope with potential funding shortages.

Results of operations

The following table sets forth the percentage of net sales represented by certain items reflected on our Consolidated Statements of Operations for the following periods:

Gross profit (loss) 14.4 3.9

Operating expenses:

Selling, general, and administrative 41.5 63.1

Total operating expenses 52.3 73.4

Loss from operations (37.9) (69.5)

Other expenses:

Interest income — (1.0)

Interest expense 0.1 6.6

Gain on debt extinguishment (3.8) —

Gain on partial lease termination (1.3) —

Other income (0.6) (0.5)

Other expenses, net 0.2 0.4

Net loss before income taxes (32.5) (75.0)

Benefit from income taxes 0.1 0.1

Net sales

A further breakdown of our net sales by product line is as follows (in thousands):

Our net sales of $4.9 million in 2024 decreased 15% compared to 2023, mainly driven by a decrease of 16% in MMM sales and a decrease of 13% in commercial sales. The decrease in net MMM product sales in 2024 as compared to 2023 was mainly due

29

Table of Contents

to a significant reduction in military demand toward the end of the year, driven by the impact of the U.S. election cycle. Net sales of our commercial products decreased in 2024 due to the effects of annual market cycles, high inflation, and our sales strategy, which reduced the proportion of commercial sales, along with market-adjusted pricing.

Gross profit (loss)

Gross profit was $0.7 million, or 14% of net sales, for 2024, compared with gross profit of $0.2 million, or 4% of net sales for 2023. The increase in gross margin was mainly driven by a 2% of net sales decrease in fixed costs such as subscription fee, expenses related to rent expense for production, a 16% of net sales decrease in variable costs such as material cost and freight in expense, and an 8% of net sales unfavorable change in inventory reserves.

The reduction in warehouse space following the new lease agreement in July 2024 required both significant disposal of highly reserved, excess and obsolete inventory and a focus on selling inventory on hand throughout 2024. As a result of our initiatives of inventory management enhancement, we sold some inventory below cost. This resulted in a net decrease of our gross inventory levels of $0.9 million and a net decrease of excess and obsolete inventory reserves of $2.2 million as compared to 2023.

Operating expenses

Product development

Product development expenses include salaries and related benefits, product testing and related costs, travel, supplies, as well as overhead items, such as depreciation and facilities costs. Product development costs are expensed as they are incurred.

Gross product development expenses were $0.5 million in 2024, a decrease of 11%, compared to $0.6 million in 2023. The $0.1 million decrease primarily resulted from lower payroll-related expenses due to a reduction in headcounts of $0.9 million. This was partially offset by a $0.4 million increase in travel expenses and a $0.4 million increase in product testing, R&D supplies, and dues. During 2024, the Company terminated several employees, and the result was a significant reduction in payroll-related expenses.

Selling, general, and administrative

Selling, general, and administrative expenses were $2.0 million, or 42% of net sales, in 2024, compared to $3.6 million, or 63% of net sales, in 2023. The year-over-year $1.6 million decrease is comprised of a combination of a $0.9 million decrease from a reduction in headcount for salaries, severance, and commissions, a $0.1 million decrease from a reduction of software costs, a $0.8 million decrease from consultant and professional fees, and remaining from a decrease of all other general expenses.

Otherexpenses (income)

Interest expenses (income)

We incurred $5 thousand in interest expenses compared to interest expenses of $380 thousand in 2023. Interest expenses primarily related to the interest on promissory notes in the principal amounts of $2 million (the “2022 Streeterville Note”) the Company sold and issued to Streeterville pursuant to separate note purchase agreements. The decrease is primarily related to early termination of the 2022 Streeterville Note.

Gain on debt extinguishment

We recognized $187 thousand of gain on debt extinguishment in 2024, which was related to the early termination of the 2022 Streeterville Note. There was no such gain recognized in 2023.

Gain on partial lease termination

We recognized $63 thousand of gain on partial lease termination in 2024, which was related to the early termination of the office lease. There was no such gain recognized in 2023.

Other income and expenses

We recognized other income of $27 thousand and $30 thousand each in 2024 and 2023, respectively. Other income in 2024 and 2023 primarily consisted of tax refunds and miscellaneous adjustments from accounts receivable.

We recognized other expenses of $10 thousand in 2024, compared to other expenses of $26 thousand in 2023. Other expenses in 2024 and 2023 primarily consisted of bank and collateral management fees.

Provision for income taxes

For each of the years ended December 31, 2024 and 2023, our effective tax rate was 0%. In 2024, our effective tax rate was lower than the statutory rate due to an increase in the valuation allowance as a result of the $3.4 million additional federal net operating loss we recognized for the year. In 2023, our effective tax rate was lower than the statutory rate due to an increase in the valuation allowance as a result of the $6.3 million additional federal net operating loss we recognized for the year.

Deferred income tax assets are reduced by a valuation allowance when it is more likely than not that some portion of the deferred income tax assets will not be realized. In considering the need for a valuation allowance, we assess all evidence, both positive and negative, available to determine whether all or some portion of the deferred tax assets will not be realized. Such evidence includes, but is not limited to, recent earnings history, projections of future income or loss, reversal patterns of existing taxable and deductible temporary differences, and tax planning strategies. We have recorded a full valuation allowance against our deferred tax assets at December 31, 2024 and 2023, respectively. We had no net deferred liabilities at December 31, 2024 or 2023. We will continue to evaluate the need for a valuation allowance on a quarterly basis.

Please refer to Note 11, “Income Taxes,” included in Item 8, “Financial Statements and Supplementary Data,” of this Annual Report for further information.

Net loss

Net loss was $1.6 million for 2024. This compares with a net loss of $4.3 million for 2023, mainly driven by reduction of cost of goods sold, product development, selling, general, and administrative expenses as well as interest expenses.

Financial condition

At December 31, 2024, we had $0.6 million in cash and no outstanding debt. We have historically incurred substantial losses, and as of December 31, 2024, we had an accumulated deficit of $154.9 million. Additionally, our sales have been concentrated among a few major customers and for the twelve months ended December 31, 2024, two customers collectively accounted for approximately 33% of net sales.

In 2024 and 2023, we recommitted to building upon the transformation activities started during 2019 that sought to stabilize and regrow our business. These efforts include the following key developments that occurred during 2024 and 2023:

•We reinvested in our MMM sales channel and are pursuing existing and new sales opportunities, though the sales cycles for what are frequently made-to-order products are longer than commercial offerings.

•We aggressively re-evaluated operating expenses and reduced its workforce significantly throughout 2023 and into 2024 to manage fixed costs.

•We continued to seek additional external funding alternatives and sources to support our growth strategies, plans and initiatives.

We continue to closely monitor our cost control efforts to streamline our operations by closely managing all spending throughout the Company, while carefully investing in new products and strategies that sought to reenergize sales.

We will seek to remain agile as an organization to respond to potential or continuing weakness in the macroeconomic environment and in the meantime seek to expand sales channels and enter new markets that we believe will provide additional growth opportunities. We plan to achieve profitability through developing and launching new, innovative products, our Redcap® emergency battery backup tubular TLEDs, evaluating new growth opportunities such as GaN-based power supply circuitry and other energy solution products, as well as executing on our multi-channel sales strategy that targets key verticals, such as government, healthcare, education and commercial and industrial, complemented by our marketing outreach campaigns and expanding channel partnerships. In addition, we intend to continue to apply rigorous financial discipline in our organizational structure, decision-making, business processes and policies, strategic sourcing activities and supply chain practices to help accelerate our path towards profitability.

Criticalaccountingpolicies andestimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that we make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingencies, and the reported amounts of net sales and expenses in the financial statements. Material differences may result in the amount and timing of net sales and expenses if different judgments or different estimates were utilized. Critical accounting policies, judgments, and estimates that we believe have the most significant impact on our financial statements are set forth below:

•revenue recognition,

•allowances for doubtful accounts, returns and discounts,

•product warranty reserve,

•valuation of inventories,

•accounting for income taxes,

•share-based compensation, and

•leases.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Stockholders and Board of Directors

Energy Focus, Inc.

Solon, Ohio

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Energy Focus, Inc. (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive loss, stockholders’ equity (deficit), and cash flows for the years then ended, and the related notes and Schedule II (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Continuation as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in the notes to the consolidated financial statements, the Company has suffered recurring losses from operations and negative cash flows from operations that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in the notes. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

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

Reserves for Excess, Obsolete and Slow-Moving Inventories

Description of the Matter

As described in Notes 2 and 4 to the consolidated financial statements, the Company assesses the valuation of inventories each reporting period based on the lower of cost or net realizable value. The Company establishes reserves for excess, obsolete and slow-moving inventories after evaluation of historical sales, current economic trends, forecasted sales, product lifecycles and current inventory levels. The assessment is both quantitative and qualitative. As of December 31, 2024, the Company had inventories of $3.3 million, net of reserves for excess, obsolete and slow-moving inventories.

35

Table of Contents

Auditing management's estimates for excess, obsolete and slow-moving inventories required subjective auditor judgment and evaluation of the reasonableness of significant assumptions used in developing the reserves as detailed above, as well as the inputs and related calculations related to historical sales and on-hand inventories.

How We Addressed the Matter in Our Audit

We obtained an understanding and evaluated the design of internal controls over the Company's reserves for excess, obsolete and slow-moving inventories, including management's assessment of the assumptions and data underlying the reserve calculation.

Our substantive audit procedures included, among others, testing the logic and integrity of calculations within management’s analysis; testing the completeness and accuracy of underlying data used, including inventory quantities, carrying costs and the estimate of net realizable value by product; and evaluating the reasonableness of management’s assumptions related to demand forecasts, estimated reserve percentages and qualitative considerations involving, among others, the implications of new or revised operational strategies. Evaluating the reasonableness of management’s assumptions involved (i) comparing historical sales by product, used as a basis for future demand, to audited sales subledgers on a sample basis, (ii) holding discussions with senior management to determine whether strategic or operational changes in the business were consistent with the projections of future demand that were utilized as the basis for the reserves recorded, and (iii) corroborating management’s qualitative considerations of future demand through review of unfulfilled customer purchase orders as of year-end on a sample basis.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.NATURE OF OPERATIONS

Energy Focus, Inc. (the “Company”) engages primarily in the design, development, manufacturing, marketing and sale of energy-efficient lighting systems and controls. We develop, market and sell high quality light-emitting diode (“LED”) lighting and controls products in the commercial market and military maritime market (“MMM”). Our mission is to enable our customers to run their facilities with greater energy efficiency, productivity, and increased human health and wellness through advanced LED retrofit solutions. Our goal is to be the human wellness lighting and LED technology and market leader for the most demanding applications where performance, quality, value, environmental impact and health are considered paramount. We specialize in LED lighting retrofit by replacing fluorescent, high-intensity discharge lighting and other types of lamps in institutional buildings for primarily indoor lighting applications with our innovative, high-quality commercial and military-grade tubular LED (“TLED”) products, as well as other LED and lighting control products for commercial applications. We are also evaluating adjacent technologies including Gallium Nitride (“GaN”) based power supplies and additional market opportunities for energy solution products that support sustainability in our existing channels. Additionally, we have expanded product offerings into both Maritime lighting and Energy Storage Solutions ( “ESS”).

NOTE 2. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies of our Company, which are summarized below, are consistent with accounting principles generally accepted in the United States (“U.S. GAAP”) and reflect practices appropriate to the business in which we operate. Unless indicated otherwise, the information in the Notes to the Consolidated Financial Statements relates to our operations.

Going Concern and Nasdaq Continued Listing Requirements Compliance

Due to our financial performance as of December 31, 2024 and 2023, including net losses of $1.6 million and $4.3 million for the twelve months ended December 31, 2024 and 2023, respectively, and total cash used in operating activities of $1.3 million and $2.4 million for the twelve months ended December 31, 2024 and 2023, respectively, we determined that substantial doubt about our ability to continue as a going concern continues to exist at December 31, 2024. As a result of restructuring actions and initiatives, we have tailored our operating expenses to be more in line with our expected sales volumes; however, we continue to incur losses and have a substantial accumulated deficit.

Additionally, global supply chain and logistics constraints are impacting our inventory purchasing strategy, as we seek to manage both shortages of available components and longer lead times in obtaining components while pursuing cost-saving measures to enhance profitability. As a result, we will continue to review and pursue selected external funding sources to ensure adequate financial resources to execute across the timelines required to achieve these objectives including, but not limited to, the following:

•obtaining financing from traditional or non-traditional investment capital organizations or individuals;

•obtaining funding from the sale of our common stock or other equity or debt instruments; and

•obtaining debt financing with lending terms that more closely match our business model and capital needs.

There can be no assurance that we will obtain funding on acceptable terms, in a timely fashion, or at all. Obtaining additional funding contains risks, including:

•additional equity financing may not be available to us on satisfactory terms, particularly in light of the current price of our common stock, and any equity we are able to issue could lead to dilution for current stockholders and have rights, preferences and privileges senior to our common stock;

•loans or other debt instruments may have terms or conditions, such as interest rate, restrictive covenants, conversion features, refinancing demands, and control or revocation provisions, which are not acceptable to management or the Company’s Board of Directors (the “Board of Directors”); and

•the current environment in the capital markets and volatile interest rates, combined with our capital constraints, may prevent us from being able to obtain adequate debt financing.

Considering both quantitative and qualitative information, we continue to believe that the combination of our plans to ensure adequate external funding, timely re-organizational actions, current financial position, liquid resources, obligations due or

44

Table of Contents ENERGY FOCUS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

anticipated within the next year, development and implementation of an excess inventory reduction plan, plans and initiatives in our research and development, product development and sales and marketing, and development of potential channel partnerships, if adequately executed, could provide us with an ability to finance our operations through the next twelve months and may mitigate the substantial doubt about our ability to continue as a going concern.

Nasdaq Capital Market Compliance

As of the date of this Annual Report, the Company believes it has maintained compliance with the Minimum Stockholders’ Equity Rule, which requires listed companies to maintain stockholders’ equity of at least $2.5 million for continued listing on the Nasdaq Capital Market. To become compliant with the Bid Price Rule, which has a minimum bid price of at least $1.00 per share as one of its continued listing requirements, the Company effected a 1-for-7 reverse stock split to increase the per share trading price of the common stock, effective June 16, 2023 (See Note 9, “Stockholders’ Equity”).

However, there can be no assurance that the Company will be able to maintain compliance with the Minimum Stockholders’ Equity Rule, Bid Price Rule, or other Nasdaq listing requirements. If the Company fails to maintain compliance with Nasdaq’s continued listing standards in accordance with the Panel’s decision, the Company’s common stock will be subject to delisting from Nasdaq.

Use of estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts in our financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact us in the future, actual results may vary from the estimates. Estimates include, but are not limited to, the expected credit loss provision, inventory obsolescence and warranty claims, the determination of the useful lives of property and equipment, valuation of long-lived assets, allowance for deferred tax assets, sales returns and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment require considerable judgment. Actual results could differ from those estimates and such differences could be material.

Basis of presentation

The Consolidated Financial Statements include the accounts of the Company. All significant inter-company balances and transactions have been eliminated. We have prepared the accompanying consolidated financial statements in accordance with U.S. GAAP and pursuant to the rules and regulations of the United States Securities & Exchange Commission (“SEC”).

Revenue

Net sales include revenues from sales of products and shipping and handling charges, net of estimates for product returns. Revenue is measured at the amount of consideration we expect to receive in exchange for the transferred products. We recognize revenue at the point in time when we transfer the promised products to the customer and the customer obtains control over the products. Distributors’ obligations to us are not contingent upon the resale of our products. We recognize revenue for shipping and handling charges at the time the goods are shipped to the customer, and the costs of outbound freight are included in cost of sales. We provide for product returns based on historical return rates. While we incur costs for sales commissions to our sales employees and outside agents, we recognize commission costs concurrent with the related revenue, as the amortization period is less than one year. We do not incur any other incremental costs to obtain contracts with our customers. Our product warranties are assurance-type warranties, which promise the customer that the products are as specified in the contract. Therefore, the product warranties are not a separate performance obligation and are accounted for as described below. Sales taxes assessed by governmental authorities and collected by us are accounted for on a net basis and are excluded from net sales.

A disaggregation of product net sales is presented in Note 11, “Product and Geographic Information.”

Accounts Receivable and Allowance for Credit Losses

Our trade accounts receivable consists of amounts billed to and currently due from customers. Substantially all our customers are concentrated in the United States. In the normal course of business, we extend unsecured credit to our customers related to the sale of our products. Credit is extended to customers based on an evaluation of the customer’s financial condition and the amounts due are stated at their estimated net realizable value. We maintain allowances for sales returns and credit losses to provide for the estimated number of account receivables that will not be collected. On January 1, 2023, the Company adopted ASC 326. The standard adds to U.S. GAAP an impairment model known as the CECL model, which is based on expected

45

Table of Contents ENERGY FOCUS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

losses rather than incurred losses. This standard only impacts the Company’s trade receivables. The Company decided to use the historical loss rate method of valuing its reserve for trade receivables. The reserve for credit losses is reviewed and assessed for adequacy on a quarterly basis. We take into consideration (1) any circumstances of which we are aware of a customer's inability to meet its financial obligations and (2) our judgments as to prevailing economic conditions in the industry and their impact on our customers. If circumstances change, and the financial condition of our customers is adversely affected and they are unable to meet their financial obligations, we may need to take additional allowances, which would result in an increase in our operating expenses. We do not generally require collateral from our customers.

Our standard payment terms with customers are net 30 days from the date of shipment, and we do not generally offer extended payment terms to our customers, but exceptions are made in some cases for major customers or with particular orders. Accordingly, we do not adjust trade accounts receivable for the effects of financing, as we expect the period between the transfer of product to the customer and the receipt of payment from the customer to be in line with our standard payment terms.

Pursuant to ASC 606, Revenue Recognition, contract assets and contract liabilities as of the beginning and ending of the reporting periods must be disclosed.Below is the breakout of the Company’s contract assets for such periods (in thousands):

Less: Reserve for Credit Losses (15) (20) (26)

Reduction of reserve for credit losses as of December 31, 2024 5

Allowance for credit losses as of December 31, 2024 $ (15)

Geographic information

All our long-lived fixed assets are located in the United States. For the years ended December 31, 2024 and 2023, approximately 100% of sales were attributable to customers in the United States. The geographic location of our net sales is derived from the destination to which we ship the product.

Cash

Cash consists of investments in money market funds and deposits with banks. At December 31, 2024 and 2023, we had cash of $0.6 million and $2.0 million, respectively, on deposit with financial institutions located in the United States.

Inventories

We state inventories at the lower of standard cost (which approximates actual cost determined using the first-in-first-out method) or net realizable value. We establish provisions for excess and obsolete inventories after evaluation of historical sales, current economic trends, forecasted sales, product lifecycles, and current inventory levels. The assessment is both quantitative and qualitative.

Income taxes

As part of the process of preparing the Consolidated Financial Statements, we are required to estimate our income tax liability in each of the jurisdictions in which we do business. This process involves estimating our actual current tax expense together with assessing temporary differences resulting from differing treatment of items, such as deferred revenues, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our Consolidated Balance Sheets. We then assess the likelihood of the deferred tax assets being recovered from future taxable income and, to the

46

Table of Contents ENERGY FOCUS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

extent we believe it is more likely than not that the deferred tax assets will not be recovered, or is unknown, we establish a valuation allowance. Significant management judgment is required in determining our provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded against our deferred tax assets. At December 31, 2024 and 2023, we recorded a full valuation allowance against our net deferred tax assets due to uncertainties related to our ability to utilize our deferred tax assets, primarily consisting of certain net operating losses carried forward. The valuation allowance is based upon our estimates of taxable income by jurisdiction and the period over which our deferred tax assets will be recoverable. In considering the need for a valuation allowance, we assess all evidence, both positive and negative, available to determine whether all or some portion of the deferred tax assets will not be realized. Such evidence includes, but is not limited to, recent earnings history, projections of future income or loss, reversal patterns of existing taxable and deductible temporary differences, and tax planning strategies. We continue to evaluate the need for a valuation allowance on a quarterly basis.

Financial Instruments

Fair value measurements

Fair value is defined as the price that would be received to sell an asset or would be paid to transfer a liability in an orderly transaction between market participants on the measurement date. The fair value of financial assets and liabilities are measured on a recurring or non-recurring basis. Financial assets and liabilities measured on a recurring basis are those that are adjusted to fair value each time a financial statement is prepared. Financial assets and liabilities measured on a non-recurring basis are those that are adjusted to fair value when a significant event occurs.

We utilize valuation techniques that maximize the use of available market information and generally accepted valuation methodologies. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value, giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

The three levels of the fair value hierarchy are described below. We classify the inputs used to measure fair value into the following hierarchy:

Level 3 Unobservable inputs for the asset or liability.

The carrying amounts of certain financial instruments including cash, accounts receivable, accounts payable, and accrued liabilities approximate fair value due to their short maturities. Based on borrowing rates currently available to us for loans with similar terms, the carrying value of borrowings under our revolving credit facilities also approximates fair value.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, we perform a detailed analysis of the assets and liabilities whose fair value is measured on a recurring basis. We review and reassess the fair value hierarchy classifications on a quarterly basis. Changes from one quarter to the next related to the observability of inputs in a fair value measurement may result in a reclassification between fair value hierarchy levels. There were no reclassifications for all periods presented.

Property and equipment

Property and equipment are stated at cost and include expenditures for additions and major improvements. Expenditures for repairs and maintenance are charged to operations as incurred. We use the straight-line method of depreciation over the estimated useful lives of the related assets (generally two to 15 years) for financial reporting purposes. Accelerated methods of depreciation are used for federal income tax purposes. When assets are sold or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any gain or loss is reflected in the Consolidated Statements of Operations.

Impairment of Long-lived assets

Long-lived assets are reviewed for impairment whenever events or circumstances indicate the carrying amount may not be recoverable. Events or circumstances that would result in an impairment review primarily include operations reporting losses, a significant change in the use of an asset, or the planned disposal or sale of the asset. The asset would be considered impaired

47

Table of Contents ENERGY FOCUS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

when the future net undiscounted cash flows generated by the asset are less than its carrying value. An impairment loss would be recognized based on the amount by which the carrying value of the asset exceeds its fair value, as determined by quoted market prices (if available) or the present value of expected future cash flows.

Refer to Note 5, “Property and Equipment,” for additional information.

Leases

The Company determines if an arrangement is a lease at its inception. A contract is or contains a lease if the contract conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. Right-of-use (“ROU”) assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments considering the term of the lease, which is derived from information available at the lease commencement date. The lease term includes renewal options when it is reasonably certain that the option will be exercised and excludes termination options.

Lease expense for these leases is recognized on a straight-line basis over the lease term. We have elected not to recognize ROU assets and lease liabilities that arise from short-term leases for any class of underlying asset. Operating leases are included in Operating lease, right-of-use-assets, Operating lease liabilities, and Long-term operating lease liabilities in our Consolidated Balance Sheets.

Product development

Product development expenses include salaries, contractor and consulting fees, supplies and materials, as well as costs related to other overhead items such as depreciation and facilities costs. Research and development costs are expensed as they are incurred. We recognized $0.5 million and $0.6 million research and development costs for the years ended December 31, 2024 and 2023, respectively.

Net loss per share

Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period, excluding the effects of any potentially dilutive securities. Diluted loss per share gives effect to all dilutive potential shares of common stock outstanding during the period. Dilutive potential shares of common stock consist of incremental shares upon the exercise of stock options, warrants and convertible securities, unless the effect would be anti-dilutive.

The following table presents a reconciliation of basic and diluted loss per share computations (in thousands, except per share amounts):

For the years ended December 31,

Numerator:

Denominator:

Basic and diluted weighted average common shares outstanding 4,947 3,241

As a result of the net loss we incurred for the years ended December 31, 2024 and 2023, convertible preferred stock representing approximately 25 thousand shares of common stock were excluded from the basic loss per share calculation because their inclusion would have been anti-dilutive.

Stock-based compensation

We recognize compensation expense based on the estimated grant date fair value under the authoritative guidance. Management applies the Black-Scholes option pricing model to value stock options issued to employees and directors and applies judgment in estimating key assumptions that are important elements of the model in expense recognition. These elements include the

48

Table of Contents ENERGY FOCUS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

expected life of the option, the expected stock-price volatility, and expected forfeiture rates. Compensation expense is generally amortized on a straight-line basis over the requisite service period, which is generally the vesting period.

See Note 9, “Stockholders’ Equity,” for additional information.

Advertising expenses

Advertising expenses are charged to operations in the period incurred. They consist of costs for the placement of our advertisements in various media and the costs of demos provided to potential distributors of our products. Advertising expenses were $6 thousand for each of the years ended December 31, 2024 and 2023, respectively.

Product warranties

We warrant our commercial and MMM LED products and controls for periods generally ranging from five to ten years. One product was sold in 2020 with a twenty-year warranty. Warranty settlement costs consist of actual amounts expensed for warranty, which are largely a result of the cost of replacement products or rework services provided to our customers. A liability for the estimated future costs under product warranties is maintained for products under warranty based on the actual claims incurred to date and the estimated nature, frequency, and costs of future claims. These estimates are inherently uncertain and changes to our historical or projected experience may cause material changes to our warranty reserves in the future. We continuously review the assumptions related to the adequacy of our warranty reserve, including product failure rates, and adjust to the existing warranty liability when there are changes to these estimates or the underlying replacement product costs, or the warranty period expires.

The following table summarizes warranty activity for the periods presented (in thousands):

At December 31,

Recently issued accounting standards

On December 14, 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. Under the new guidance, entities must consistently categorize and provide greater disaggregation of information in the rate reconciliation. They must also further disaggregate income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The guidance applies to all entities subject to income taxes and is effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company plans to

49

Table of Contents ENERGY FOCUS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

adopt this standard on January 1, 2025. We are currently evaluating the impact this ASU will have on our financial statements and disclosures.

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. ASU 2023-06 modifies the disclosure or presentation requirements of a variety of Topics in the Codification. Certain of the amendments represent clarifications to or technical corrections of the current requirements. Because of the variety of Topics amended, a broad range of entities may be affected by one or more of those amendments. Many of the amendments allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the SEC’s requirements. Also, the amendments align the requirements in the Codification with the SEC’s regulations. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. For all other entities, the amendments will be effective two years later. The amendments in this update should be applied prospectively. For all entities, if by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. The Company is currently evaluating the potential impact this standard will have on its consolidated financial statements and related disclosures.

Recently adopted accounting standards

On November 27, 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting-Improvements to Reportable Segment Disclosures, which requires public entities to provide disclosures of significant segment expenses and other segment items. The guidance requires public entities to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually and also applies to public entities with a single reportable segment. Entities are permitted to disclose more than one measure of a segment’s profit or loss if such measures are used by the chief operating decision-maker to allocate resources and assess performance, as long as at least one of those measures is determined in a way that is most consistent with the measurement principles used to measure the corresponding amounts in the consolidated financial statements. The guidance is applied retrospectively to all periods presented in financial statements, unless it is impracticable, and is effective for fiscal years beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. Early adoption is permitted. The Company adopted ASU 2023-07 in 2024. Refer to Note 11 for related disclosures.

Other accounting standards that have been issued by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. We do not discuss recent standards that are not anticipated to have an impact on or are unrelated to our consolidated financial condition, results of operations, cash flows or disclosures.

Certain risks and concentrations

We have certain customers whose net sales individually represented 10% or more of our total net sales, or whose net trade accounts receivable balance individually represented 10% or more of our total net trade accounts receivable as follows:

•In 2024, two customers collectively accounted for 33% of net sales, with sales to our primary distributor for the U.S. Navy accounting for approximately 16% and sales to a shipbuilder for the U.S. Navy accounting for approximately 17%. In 2023, two customers collectively accounted for 48% of net sales, with sales to our primary distributor for the U.S. Navy accounting for approximately 35% and sales to a shipbuilder for the U.S. Navy accounting for approximately 13%.

•At December 31, 2024, three customers collectively accounted for 88% of our net trade accounts receivables. This including approximately 21% from distributor to the U.S. Navy, approximately 52% from shipbuilder to the U.S. Navy, and approximately 15% from commercial customer accounts. At December 31, 2023, one distributor to the U.S. Department of Defense accounted for 74% of our net trade accounts receivable, when combined with our net trade accounts receivable to shipbuilders for the U.S. Navy, total net accounts receivable related to U.S. Navy sales is 78% of total net accounts receivable.

We require substantial amounts of purchased materials from selected vendors. With specific materials, all of our purchases are from a single vendor. The availability and costs of materials may be subject to change due to, among other things, new laws or regulations, suppliers’ allocation to other purchasers, interruptions in production by suppliers, global health issues such as the

50

Table of Contents ENERGY FOCUS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

COVID-19 pandemic, and changes in exchange rates and worldwide price and demand levels. Our inability to obtain adequate supplies of materials for our products at favorable prices could have a material adverse effect on our business, financial position, or results of operations by decreasing our profit margins and by hindering our ability to deliver products to our customers on a timely basis. Additionally, certain vendors require advance deposits prior to the fulfillment of orders. Deposits paid on unfulfilled orders totaled $0.4 million and $0.8 million at December 31, 2024 and 2023, respectively.

We have certain vendors who individually represented 10% or more of our total expenditures, or whose net trade accounts payable balance individually represented 10% or more of our total net trade accounts payable, as follows:

•One offshore supplier accounted for approximately 36% of our total expenditures for the twelve months ended December 31, 2024. At December 31, 2024, two offshore suppliers collectively accounted for approximately 36% and 54% (a related party, See Note 12, “Related Party Transactions”) of our trade accounts payable balance, respectively.

•No offshore supplier accounted for more than 10% of our total expenditures for the twelve months ended December 31, 2023. At December 31, 2023, two offshore suppliers accounted for approximately 16% and 57% (a related party, See Note 12, “Related Party Transactions”) of our trade accounts payable balance, respectively.

NOTE 3. LEASES

The Company leases certain equipment, manufacturing, warehouse and office space under non-cancellable operating leases with expirations through 2027 under which it is responsible for related maintenance, taxes and insurance. As of March 25, 2022, the terms of our real estate operating lease have been modified beginning July 1, 2022 and extended through 2027. Additionally, Effective July 1, 2024, our warehouse and office lease was amended to reduce the rentable square feet from 62,335 square feet to 29,692 square feet and the rent expenses were decreased in proportion to the reduction in rentable square. The Company recorded this as a lease modification in accordance with ASC 842 Leases (“ASC 842”) and recorded a reduction to the right of use asset and lease liability of approximately $395 thousand using an incremental borrowing rate of approximately 13.64%. The Company recognized a gain on the lease modification of $63 thousand which was recorded as other income in the Statement of Operations. The weighted average remaining lease term for the operating leases is 2.5 years.
