 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.

 In 2024, we recommitted to building upon the transformation activities that sought to stabilize and regrow our business. These efforts include the following key developments that occurred during 2024:
 • On June 12, 2024, the Board approved the departure of Jason Tien-Chia Tsai and appointed Wen Cheng Chen as a new member. All current Board members other than our CEO Mr. Huang remain independent directors under the corporate governance standards of Nasdaq.

 • On January 18, 2024, the Company and Streeterville Capital, LLC ("Streeterville") entered into a payoff letter and exchange agreement (the "Agreement") to pay off a note entered into by and between the Company and Streeterville in 2022 (the "2022 Streeterville Note") early. The Agreement provided that the Company made payments to reduce the outstanding obligations under the 2022 Streeterville Note of $1.0 million in cash by January 19, 2024 and exchange 94,440 shares of common stock by January 23, 2024 for the remaining $142 thousand. In January 2024, the Company paid off the 2022 Streeterville Note in full. At termination, the Company recognized $187 thousand of other income which was included in other income in the Condensed Consolidated Statements of Operations.

 • On March 28, 2024, Energy Focus, Inc. entered into certain securities purchase agreements with certain accredited investors, pursuant to which the Company agreed to issue and sell in a private placement an aggregate of 283,019 shares of the Company's common stock, par value $0.0001 per share, for a purchase price per share of $1.59 (the "First Private Placement"). Aggregate gross proceeds to the Company with respect to the First Private Placement were approximately $450 thousand, excluding the offering expenses paid by the Company. The First Private Placement was closed on March 28, 2024.

 • On June 21, 2024, Energy Focus, Inc. entered into certain securities purchase agreements with certain accredited investors, pursuant to which the Company agreed to issue and sell in a private placement an aggregate of 534,591 shares of the Company's common stock, par value $0.0001 per share, for a purchase price per share of $1.59 (the "Second Private Placement"). Aggregate gross proceeds to the Company with respect to the Second Private Placement were approximately $850 thousand, excluding the offering expenses paid by the Company. The Second Private Placement was closed on June 21, 2024.

 • In 2024, we carefully researched and analyzed our historical sales data and the current market landscape, focusing on our pricing position and overall sales strategy. We acknowledged the increasing competition in the MMM sales space, both in terms of pricing pressure and the growing number of competitors.

 • The Company has aggressively re-evaluated operating expenses throughout the year to manage fixed costs.

 During 2024, we have thoroughly reviewed and adjusted our commercial pricing position as well as our strategic relationships and partnerships within the commercial LED market space.

 In 2023, two customers accounted for 48% of net sales, with sales to our primary distributor for the U.S. Navy accounting for approximately 35% of net sales, and sales to a shipbuilder for the U.S. Navy accounting for approximately 13% of net sales.
 Competition
 Our LED lighting products compete against a variety of lighting products, including conventional light sources such as compact fluorescent lamps and HID lamps, as well as other TLEDs and integrated LED luminaire products. Our ability to compete depends substantially upon the superior performance, incremental benefits and lower total cost of ownership of our products. Principal competitors in our markets include large lamp manufacturers and lighting fixture companies based in the United States, as well as TLED and LED replacement fixture manufacturers mostly based in Asia, whose financial resources may substantially exceed ours and whose cost structure as a percentage of sales may be well below ours. These competitors may introduce new or improved products that may reduce or eliminate some of the competitive advantage of our products and may have substantially lower pricing. We anticipate that the competition for our products will also come from new technologies that offer increased energy efficiency, lower initial costs, lower maintenance costs, or advanced features. We compete with LED systems produced by large lighting companies such as Signify Lighting, Osram Sylvania and GE Lighting, as well as smaller manufacturers or distributors such as LED Smart, Energy Source Group, Orion Energy Systems, and Keystone Technologies. Some of these competitors offer products with performance characteristics similar to those of our products.

 Manufacturing and Suppliers
 We manufacture our lighting products and systems through a combination of in-house production at our Solon, Ohio facility and outsourced finished goods produced to our specifications. Our in-house operations focus on final assembly, testing, and quality control. We collaborate with several vendors to design custom components that meet our specific needs. Our quality assurance program includes rigorous testing at key stages of assembly and for all finished products, whether produced internally or sourced externally. Additionally, we are ISO 9001:2015 certified.
 Manufacturing costs are managed through a balance of internal production and outsourcing to trusted suppliers worldwide, primarily in the United States, Malaysia, Taiwan, and previously China. In certain cases, we rely on single-source suppliers for specific components or finished goods. We continuously optimize our global supply chain to meet client expectations in quality and volume while controlling costs and achieving target gross margins. Our approach includes evaluating opportunities for additional outsourcing or increased insourcing when it enhances cost efficiency, quality, or performance.
 Our suppliers are primarily based in Asia. We continue to reduce transportation costs while actively managing shorter lead times for component procurement.
 One offshore supplier (a related party, See Note 12 "Related Party Transactions") accounted for approximately 36% of our total expenditures for the twelve months ended December 31, 2024. At December 31, 2024, two offshore suppliers accounted for approximately 36% and 54% (a related party, See Note 12, "Related Party Transactions" of this Annual Report on Form 10-K, for additional information) 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 this Annual Report on Form 10-K, for additional information) of our trade accounts payable balance, respectively.
 Product Development
 Product development remains a central focus and a key differentiator in delivering industry-leading LED lighting solutions, GaN Power Supplies, and MMM lighting solutions. Gross product development expenses for the years ended December 31, 2024 and 2023 were $0.5 million and $0.6 million, respectively. We believe that our customer-focused approach to product development ensures that our R&D investments yield impactful and innovative products, driving faster market adoption and strengthening our competitive advantage.
 Intellectual Property
 We actively protect our intellectual property through patents, license agreements, trademark registrations, confidential disclosure agreements, and trade secrets, as appropriate. Certain patents are integral to our current product lines. We have multiple pending U.S. and international patent applications filed under the Patent Cooperation Treaty with the World Intellectual Property Organization. Our portfolio includes over 50 issued patents, expiring at various times through May 2040. Patent protection typically lasts 20 years from the earliest effective filing date. However, there is no guarantee that existing patents are invulnerable or that pending applications will be granted. Competitors may develop similar products or access proprietary information despite these protections. The laws of some foreign countries in which we manufacture, sell or may sell our products do not protect proprietary rights to products to the same extent as the laws of the United States. Please refer to Note 8, "Commitments and Contingencies," of this Annual Report on Form 10-K, for additional information.
 Insurance
 All of our properties and equipment are covered by insurance and we believe that such insurance is adequate. In addition, we maintain general liability, product recall and workers' compensation insurance in amounts we believe to be consistent with our risk of loss and industry practice.
 Regulatory Compliance
 We derive a significant portion of our revenues from direct and indirect sales to U.S., state, local and foreign governments and their respective agencies. Contracts with government customers are subject to various procurement laws and regulations, business prerequisites to qualify for such contracts, accounting procedures, intellectual property processes, and contract provisions relating to their formation, administration and performance, which may provide for various rights and remedies in favor of the governments that are not typically applicable to or found in commercial contracts.

 In addition, although not legally required to do so, we strive to obtain certification for substantially all our products. In the United States, we seek certification on substantially all of our products from UL, Intertek Testing Services ("ETL "), or DesignLights Consortium ("DLC "). Where appropriate in jurisdictions outside the United States, we seek to obtain other similar national or regional certifications for our products. Although we believe that our broad knowledge and experience with electrical codes and safety standards have facilitated certification approvals, we cannot ensure that we will be able to obtain any such certifications for our new products or that, if certification standards are amended, we will be able to maintain such certifications for our existing products.
 Human Capital
 As of December 31, 2024, we had 9 full-time employees and 4 part-time employees, with 9 based in the United States and 4 in Taiwan. We had two temporary contractors as of December 31, 2024. None of our employees or contractors are subject to collective bargaining agreements and we consider our relationship with our employees to be good. We encourage and support the growth and development of our employees. Continual learning and career development is advanced through ongoing performance and development conversations with employees and reimbursement is available to employees from time to time for seminars, conferences, formal education, and other training events employees attend in connection with their job duties.
 Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our current and future employees. The principal purposes of our annual bonus plan and equity incentive plan are to attract, retain and motivate employees through the granting of long-term incentive compensation awards.
 Business Segments
 We currently operate in a single business segment that includes the marketing and sale of commercial and MMM lighting products and controls. Please refer to Note 11, "Product and Geographic Information," included in Item 8, "Financial Statements and Supplementary Data," of this Annual Report on Form 10-K, for additional information.

 Risks Associated with Our Business
 If we are unable to attract or retain qualified personnel, our business and product development efforts could be harmed.
 We are highly dependent on our senior management and other key personnel due to our very lean organizational structure. Our future success will depend on our ability to attract, retain, develop and motivate qualified executive, technical, sales, marketing, operating, financial and management personnel, for whom competition is very intense. As we attempt to sustain and re-grow our business, it could be especially difficult to attract, retain and adequately compensate qualified personnel, especially in light of our lean cost structure and the tightening of the labor market, which has led to increased competition for employees. The loss of, or failure to attract, hire, and retain any such persons could delay product development cycles, disrupt our operations, increase our costs, or otherwise harm our business or results of operations. We also do not maintain "key person" insurance policies on any of our officers or our other employees, nor have employment contracts.
 We rely on equity and debt financing to operate our business and will require additional financing in the near term, which we may not be able to raise on favorable terms or at all, and our failure to obtain funding when needed may force us to delay, scale back or eliminate our business plan or even discontinue or curtail our operations.
 For the year ended December 31, 2024, we reported a net loss of $1.6 million and are dependent upon the availability of financing in order to continue our business.
 For the year ended December 31, 2024, financing activity to sustain ongoing losses included (1) proceeds from the issuance of common stock and warrants approximately $0.9 million and (2) payment on the 2022 Streeterville Note $1.0 million (Please see Note 7 of our financial statements for the year ended December 31, 2024 included in Part II, Item 8, "Financial Statements and Supplementary Data," of this Annual Report.).

 For the year ended December 31, 2023, financing activity to sustain ongoing losses included (1) selling an aggregate of approximately $6.1 million common stock through several private placement transactions and (2) converting approximately $1.7 million of outstanding promissory notes into common stock.

 We may not generate sufficient cash flows from our operations or be able to borrow sufficient funds to sustain our operations. As such, we will likely need additional external financing during 2025 and will continue to review and pursue external funding sources 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 financing contains risks, including:
 • additional equity financing may not be available to us on satisfactory terms 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 rates, restrictive covenants and control or revocation provisions, which are not acceptable to management or our Board of Directors; and
 • the current environment in the capital markets combined with our capital constraints may prevent us from being able to obtain adequate debt financing.
 If we fail to obtain the required additional financing to sustain our business before we are able to produce levels of revenue to meet our financial needs, we will need to delay, scale back or eliminate our business plan and further reduce our operating costs and headcount, each of which would have a material adverse effect on our business, future prospects, and financial condition. A lack of additional financing could also result in our inability to continue as a going concern and force us to sell certain assets or discontinue or curtail our operations and, as a result, investors in the Company could lose their entire investment.
 Our independent registered public accounting firm's opinion on our audited financial statements for the fiscal year ended December 31, 2024, included in this Annual Report, contains a modification relating to our ability to continue as a going concern.
 Our independent registered public accounting firm's opinion on our audited financial statements for the year ended December 31, 2024 includes a modification stating that our losses and negative cash flows from operations and uncertainty in

 generating sufficient cash to meet our obligations and sustain our operations raise substantial doubt about our ability to continue as a going concern.
 While we continue to pursue funding sources and transactions that could raise capital, there can be no assurances that we will be successful in these efforts or will be able to resolve our liquidity issues or eliminate our operating losses. If we are unable to generate enough cash or obtain sufficient additional funding, we would need to scale back or significantly adjust our business plan, further reduce our operating costs and headcount, or discontinue or curtail our operations. Accordingly, our business, prospects, financial condition and results of operations could be materially and adversely affected, and we may be unable to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited consolidated financial statements, and it is likely that investors will lose all or a part of their investment. Our financial statements do not include any adjustments that might result from the outcome of this uncertainty. (Please see Note 2 of our financial statements "Going Concern" for the year ended December 31, 2024 included in Part II, Item 8, "Financial Statements and Supplementary Data," of this Annual Report.)
 We have a history of operating losses and will incur losses in the future as we continue our efforts to grow sales and streamline our operations at a profitable level.
 We have incurred substantial losses in the past and reported net losses from operations of $1.6 million and $4.3 million for the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024, we had an accumulated deficit of $154.9 million and cash of approximately $0.6 million, compared to an accumulated deficit of $153.3 million and cash of approximately $2.0 million as of December 31, 2023.
 In order for us to operate our business profitably, we need to grow our sales, maintain cost control discipline while balancing development of our product pipeline and potential long-term revenue growth, continue our efforts to reduce product cost, and drive further operating efficiencies and develop and execute a strategic product pipeline for profitable and compelling MMM and LED lighting and control products. Management plans to expand into the Asian market in 2025. There is a risk that our strategy to return to profitability may not be as successful as we envision, or occur as quickly as we expect. We might require additional financing in the near-term and, if our operations do not achieve, or we experience an unanticipated delay in achieving, our intended level and pace of profitability, we will continue to need additional funding, none of which may be available on favorable terms or at all and could require us to sell certain assets or discontinue or curtail our operations.

 While we are attempting to diversify our customer base, we have historically derived a significant portion of our revenue from a few customers, and the loss of one of these customers, or a reduction in their demand for our products, could adversely affect our business, financial condition, results of operations, and prospects.
 Historically our customer base has been highly concentrated and a few customers have represented a substantial portion of our net sales. In 2024, two customers collectively accounted for 33% of net sales. Total sales to our primary distributor to the U.S. Navy, combined with sales to shipbuilders for the U.S. Navy represented 33% of net sales in 2024. In 2023, two customers collectively accounted for 48% of net sales. Total sales to our primary distributor to the U.S. Navy, combined with sales to shipbuilders for the U.S. Navy represented 70% of net sales in 2023.
 We generally do not have long-term contracts with our customers that commit them to purchase any minimum amount of our products or require them to continue to do business with us. We could lose business from any one of our significant customers for a variety of reasons, many of which are outside of our control, including ongoing long-term impacts of the COVID-19 pandemic, changes in levels of government funding and rebate programs, our inability to comply with government contracting laws and regulations, changes in customers' procurement strategies or their lighting retrofit plans, changes in product specifications, additional competitors entering particular markets, our failure to keep pace with technological advances and cost reductions, and damage to our professional reputation, among others.
 We are attempting to expand and diversify our customer base and reduce the dependence on one or a few customers, through the addition of sales representatives and other potential sales channels, but we cannot provide any assurance that our efforts will be successful. We anticipate that a limited number of customers could continue to comprise a substantial portion of our revenue for the foreseeable future. If we continue to do business with our significant customers, our concentration can cause variability in our results because we cannot control the timing or amounts of their purchases. A significant customer could cease to do or drastically reduce its business with us with little or no notice, which could adversely affect our results of operations and cash flows in particular periods.
 Historically, we have experienced long sales-cycles, as well as slow ramp-up by new customers to purchase large amounts of LED products from us. Given the fiercely competitive lighting market in which we operate, we are constantly trying to balance pricing with the quality-premium our products command both in brand reputation and performance. As a result, adding new customers could generally be a slow process, and increasing new customers' sales to more significant levels usually takes a

 long period of time. As we continue to develop more customer-centric new products such as GaN-based power supply circuitry, we hope to both add new customers more quickly and have our customers scale their purchasing levels more quickly. However, there is no guarantee of faster customer acceptance or performance of these new products or any other that has been or is being developed.
 If critical components and finished products that we develop with and purchase from a small number of third-party development partners and suppliers become unavailable or increase in price, or if our development partners, suppliers or delivery channels fail to meet our requirements for quality, quantity, and timeliness, our revenue and reputation in the marketplace could be harmed, which would damage our business.
 In an effort to reduce research and development and manufacturing costs, we have outsourced the research, development and production of certain parts and components, as well as finished goods in our product lines, to a small number of vendors in various locations throughout the world, primarily in the United States, Malaysia, Taiwan and China. We generally purchase these sole or limited source items with purchase orders, and we have limited guaranteed supply arrangements with such suppliers. While we believe alternative sources for these components and products are available, we select suppliers based on their expected ability to provide quality products at a cost-effective price, to meet our specifications, and to deliver within scheduled time frames. We do not control the time and resources that these suppliers devote to our business, and we cannot be sure that these suppliers will perform their obligations to us. If our ability to manage third-party product development efforts are unsuccessful or our suppliers fail to perform their obligations in a timely manner or at satisfactory quality levels, we may suffer lost or delayed sales, increased costs of goods sold, reductions in revenue or margin, and damage to our reputation in the market, all of which would adversely affect our business. As demand for our products fluctuates, which fluctuations can be hard to predict, we may not need a sustained level of inventory, which may cause financial hardship for our suppliers or they may need to divert production capacity elsewhere. In the past, we have had to purchase quantities of certain components that are critical to our product manufacturing and were in excess of our estimated near-term requirements as a result of supplier delivery constraints and concerns over component availability, and we may need to do so in the future. As a result, we have had, and may need to continue, to devote additional working capital to support a large amount of component and raw material inventory that may not be used over a reasonable period to produce saleable products, and we may be required to increase our excess and obsolete inventory reserves to provide for these excess quantities, particularly if demand for our products does not meet our expectations.
 We may be vulnerable to unanticipated product development delays, price increases and payment term changes. Significant increases in the prices of sourced components and products, shipping costs and recent tariff policy changes could cause our product prices to increase, which may reduce demand for our products or make us more susceptible to competition. Furthermore, in the event that we are unable to pass along increases in operating costs to our customers, margins and profitability may be adversely affected. Accordingly, the loss of all or one of these suppliers could have a material adverse effect on our operations until such time as an alternative supplier could be found.
 Additionally, consolidation in the lighting industry could result in one or more current suppliers being acquired by a competitor, rendering us unable to continue purchasing key components and products at competitive prices.
 We also may be subject to various import duties and tariffs applicable to materials manufactured in foreign countries and may be affected by various other import and export restrictions, as well as other considerations or developments impacting upon international trade, including economic or political instability, tariffs, shipping delays and product quotas. These international trade factors will, under certain circumstances, have an impact on the cost of components, which will have an impact on the cost to us of the manufactured product and the wholesale and retail prices of our products.
 We rely on arrangements with independent shipping companies for the delivery of our products from vendors abroad. The failure or inability of these shipping companies to deliver products or the unavailability of shipping or port services, even temporarily, could have a material adverse effect on our business. We may also be adversely affected by an increase in freight surcharges due to global logistics capacity constraints, rising fuel costs and added security costs.
 If we are unable to implement plans to increase sales and control expenses to manage future growth effectively, our profitability goals and liquidity will be adversely affected.
 Our ability to achieve our desired growth depends on the adoption of high-quality LED lighting and controls within the general lighting market and our ability to affect and adapt to these rates of adoption. The pace of continued growth in these markets is uncertain, and in order to grow our sales, we may need to:
 • manage organizational complexity and ensure effective and timely communication;
 • expand the skills and capabilities of our current management, engineering and sales teams;
 • add experienced senior level managers;

 • attract, retain and adequately compensate qualified employees;
 • adequately maintain and adjust the operational and financial controls that support our business;
 • expand research and development, sales and marketing, technical support, distribution capabilities, manufacturing planning or administrative functions and capabilities;
 • maintain or establish additional manufacturing facilities and equipment, as well as secure sufficient third-party manufacturing resources, to adequately meet customer demand or lower manufacturing costs; and
 • manage an increasingly complex supply chain to maintain a sufficient supply of materials and deliver on time to our manufacturing facilities.
 These efforts to grow our business, both in terms of size and in diversity of customer bases served, may put a significant strain on our resources. We have implemented comprehensive cost-saving initiatives to reduce our net loss and mitigate doubt about our ability to continue as a going concern. These initiatives have improved efficiency and streamlined our operations, but we continue to operate at a loss and may need additional funding or further cost-cutting to manage liquidity.
 Our possible future growth may exceed our current capacity and require rapid expansion in certain functional areas. We may lack sufficient funding to appropriately expand or incur significant expenses as we attempt to scale our resources and make investments in our business that we believe are necessary to achieve short-term and long-term growth goals. Such investments take time to become fully operational, and we may not be able to expand quickly enough to exploit targeted market opportunities. In addition to our own manufacturing capacity, we are increasingly utilizing contract manufacturers and original design manufacturers ("ODMs") to produce our products for us. There are also inherent execution risks in expanding product lines and production capacity, whether through our facilities or that of a third-party manufacturer, that could increase costs and reduce our operating results, including design and construction cost overruns, poor production process yields and reduced quality control. If we are unable to fund any necessary expansion or manage our growth effectively, we may not be able to adequately meet demand, our expenses could increase without a proportionate increase in revenue, our margins could decrease, and our business and results of operations could be adversely affected.
 Our results of operations, financial condition and business could be harmed if we are unable to balance customer demand and capacity.
 As our customer base and customer demand for our products changes and as we launch new products, we must be able to adjust our production capacity to meet demand. We are continually taking steps to address our manufacturing capacity needs for our products. If we are not able to increase or decrease our production capacity at our targeted rate or if there are unforeseen costs associated with adjusting our capacity levels or there are unanticipated interruptions in our global supply chain or logistics from such possibilities as long-term effects of the COVID-19 pandemic, geopolitical tension as the military conflict in Ukraine and the Middle East, shifting workforces, or energy policies, we may not be able to achieve our financial targets. In addition, as we introduce new products and further refine existing products, we must balance the production and inventory of prior generation products with the production and inventory of new products, whether manufactured by us or our contract manufacturers, to maintain a product mix that will satisfy customer demand and mitigate the risk of incurring cost write-downs on the previous generation products, related raw materials and tooling.
 If customer demand does not materialize at the rate forecasted, we may not be able to scale back our manufacturing expenses or overhead costs to correspond to the demand. This could result in lower margins, write-downs of our inventory and adverse impacts to our business and results of operations. Additionally, if product demand decreases or we fail to forecast demand accurately, our results may be adversely impacted due to higher costs resulting from lower factory utilization, causing higher fixed costs per unit produced. In addition, our efforts to improve quoted delivery lead-time performance may result in corresponding reductions in order backlog. A decline in backlog levels could result in more variability and less predictability in our quarter-to-quarter net sales and operating results.
 If we are not able to compete effectively against companies with lower cost structures or greater resources, or new competitors who enter our target markets, our sales will be adversely affected.
 The lighting industry is highly competitive. In the high-performance lighting markets in which we sell our advanced lighting systems, our products compete with lighting products utilizing traditional lighting technology provided by many vendors. Our higher quality and value advanced lighting and control systems also face competition from lower quality, commodity lighting products when customers may be overly purchase-price sensitive. For sales of MMM products, we compete with a small number of qualified military lighting lamp and fixture suppliers. In certain commercial applications, we typically compete with LED systems produced by large lighting companies. Our primary competitors include Signify, Osram Sylvania, LED Smart, Energy Source Group, Orion Energy Systems, and Keystone Technologies. Some of these competitors offer products with performance characteristics similar to those of our products. Many of our competitors are larger, more established companies

 with greater resources to devote to research and development, manufacturing and marketing, as well as greater brand recognition. In addition, larger competitors who purchase greater unit volumes from component suppliers may be able to negotiate lower costs, thereby enabling them to offer lower pricing to end customers. Moreover, the relatively low barriers to entry into the lighting industry and the limited proprietary nature of many lighting products also permit new competitors to enter the industry easily and with lower costs.
 In each of our markets, we also anticipate the possibility that LED component manufacturers, including those that currently supply us with LEDs, may seek to compete with us. Our competitors' lighting technologies and products may be more readily accepted by customers than our products will be. Moreover, if one or more of our competitors or suppliers were to merge, the change in the competitive landscape could adversely affect our competitive position. Additionally, to the extent that competition in our markets intensifies, we may be required to further reduce our prices in order to remain competitive. If we do not compete effectively, or if we reduce our prices without making commensurate reductions in our costs, our net sales, margins, and profitability and our future prospects for success may be harmed.
 We work with independent agents and sales representatives for a portion of our net sales, and the failure to incentivize, retain and manage our relationships with these third parties, or the termination of these relationships, could cause our net sales to decline and harm our business.
 In the past, we pursued an agency-driven sales channel strategy in order to expand our market presence throughout the United States. As a result, at that time, we had increased our reliance on independent sales agent channels to market and sell our LED lighting and control products. In addition, these parties provide technical sales support to end-users. The current agreements with our agents are generally non-exclusive on the agents' product portfolio, meaning they can sell our competitors' products. Any such agreements we enter into in the future may be on similar terms. Our agents may not be motivated to or successfully pursue the sales opportunities available to them, or they may prefer to sell or be more familiar with the products of our competitors. If our agents do not achieve our sales objectives or these relationships take significant time to develop, our revenue may decline, fail to grow or not increase as rapidly as we intend in order to achieve profitability and grow our business. We improved and continued to maintain our agency relationships that were both mutually beneficial and strategically important. Although we believe that our agency strategy will increase the role of independent agents and sales representatives over time, direct sales using internal sales personnel still account for a substantial portion of our sales, and our agency plans may take longer to contribute significantly to our operating results.
 Furthermore, our agency agreements are generally short-term and can be cancelled by either party without significant financial consequence. The termination of or the inability to negotiate extensions of these contracts on acceptable terms could adversely impact sales of our products. Additionally, we cannot be certain that we or end-users will be satisfied by their performance. If these agents significantly change their terms with us, or change their end-user relationships, there could be an impact on our net sales and profits.
 If our LED lighting and control technology products fail to gain widespread market acceptance or we are unable to respond effectively as new technologies and market trends emerge, our competitive position and our ability to generate revenue, and profits may be harmed.
 To be successful in our respective markets for LED lighting and control technology products, we depend on continued market acceptance of our existing LED lighting and control technology, including in the consumer and commercial markets. Potential customers may be reluctant to adopt LED lighting products as an alternative to traditional lighting technology because of their higher initial costs or perceived risks relating to their novelty, reliability, usefulness, quality and cost-effectiveness when compared to other established lighting sources available in the market. Changes in economic and market conditions may also make traditional lighting technologies more appealing. For example, declining energy prices in certain regions or countries may favor existing lighting technologies that are less energy-efficient, reducing the rate of adoption for LED lighting products in those areas. Notwithstanding continued performance improvements and cost reductions of LED lighting technologies, limited customer awareness of the benefits of LED lighting products, lack of widely accepted standards governing LED lighting products and customer unwillingness to adopt LED lighting products could significantly limit the demand for LED lighting products. Even potential customers that are inclined to adopt energy-efficient lighting technology may defer investment as LED lighting products continue to experience rapid technological advances. Any of the foregoing could adversely impact our results of operations and limit our market opportunities.
 In addition, we will need to keep pace with rapid changes in LED lighting and control technology, changing customer requirements, new product introductions and cost reductions by competitors and evolving industry standards, any of which could render our existing products obsolete if we fail to respond in a timely manner. The development, introduction, and

 acceptance of new, re-designed or reduced cost products incorporating advanced technology is a complex process subject to numerous uncertainties, including:
 • available funding to sustain adequate development efforts;
 • achievement of technology breakthroughs required to make commercially viable devices, and in turn, protecting those breakthroughs through intellectual property;
 • the accuracy of our predictions for market requirements;
 • our ability to predict, influence, or react to evolving standards;
 • acceptance of our new product designs;
 • acceptance of new technologies in certain markets;
 • the combination of other desired technological advances with lighting products, such as controls;
 • the availability of qualified research and development personnel;
 • our timely completion of product designs and development;
 • our ability to develop repeatable processes to manufacture new products in sufficient quantities, with the desired specifications, and at competitive costs;
 • our ability to effectively transfer products and technology from development to manufacturing; and
 • market acceptance of our products.
 We could experience delays in the introduction of these products. We could also devote substantial resources to the development of new technologies or products that are ultimately not successful.
 If effective new sources of light, other than LEDs, are discovered and commercialized, our current products and technologies could become less competitive or obsolete. If others develop innovative proprietary lighting technology that is superior to ours, or if we fail to accurately anticipate technology, pricing and market trends, address market saturation and customer confusion, respond on a timely basis with our own development of new and reliable products and enhancements to existing products, and achieve broad market acceptance of these products and enhancements, our competitive position may be harmed and we may not achieve sufficient growth in our net sales to attain or sustain profitability.
 Our operating results may fluctuate due to factors that are difficult to forecast and not within our control.
 Our past operating results may not be accurate indicators of future performance, and you should not rely on such results to predict our future performance. Our operating results have fluctuated significantly in the past and could fluctuate in the future. Factors that may contribute to fluctuations include:
 • changes in aggregate capital spending, cyclicality and other economic conditions, including inflationary pressures, or domestic and international demand in the industries;
 • the timing of large customer orders to which we may have limited visibility and cannot control;
 • competition for our products, including the entry of new competitors and significant declines in competitive pricing;
 • our ability to effectively manage our working capital;
 • our ability to generate increased demand in our current and targeted markets, particularly those in which we have limited experience;
 • our ability to satisfy customer demands in a timely and cost-effective manner;
 • pricing and availability of labor and materials;
 • quality testing and reliability of new products;
 • our inability to adjust certain fixed costs and expenses for changes in demand and the timing and significance of expenditures that may be incurred to facilitate our growth;
 • macroeconomic, geopolitical and health concerns, including long-term effects of the COVID-19 pandemic;
 • seasonal fluctuations in demand and our revenue; and
 • disruption in component supply from foreign vendors.
 Depressed general economic conditions may adversely affect our operating results and financial condition.
 Our business is sensitive to changes in general economic conditions, both inside and outside the United States. Slow growth in the economy or an economic downturn, particularly one affecting construction and building renovation, or that causes end-users to reduce or delay their purchases of lighting products, services, or retrofit activities, would have a material adverse effect on our business, cash flows, financial condition and results of operations. LED lighting retrofit projects, in particular, tend to require a significant capital commitment, which is offset by cost savings achieved over time. As such, a lack of available capital, whether due to economic factors or conditions in the equity or debt markets, could have the effect of reducing demand for our products. A decrease in demand could adversely affect our ability to meet our working capital requirements and growth objectives, or could otherwise adversely affect our business, financial condition, and results of operations.

 Customers may be unable to obtain financing to make purchases from us.
 Some of our customers require financing in order to purchase our products, and the initial investment is higher than that which is required with traditional lighting products. The potential cost or inability of these customers to access the capital needed to finance purchases of our products and meet their payment obligations to us could adversely impact the appeal of our products relative to those with lower upfront costs and have a negative impact on our financial condition and results of operations. There can be no assurance that third-party finance companies will provide capital to our customers.
 A significant portion of our business is dependent upon the existence of government funding, which may not be available into the future and could result in a reduction in sales and harm to our business.
 Some of our customers are dependent on governmental funding, including U.S. and foreign allied navies and U.S. military bases. If any of these customers or potential customers abandon, curtail, or delay planned LED lighting retrofit projects as a result of the levels of funding available to them or changes in budget priorities, it would adversely affect our opportunities to generate product sales.
 Our products could contain defects, or they may be installed or operated incorrectly, which could reduce sales of those products or result in claims against us.
 Despite product testing, defects may be found in our existing or future products. This could result in, among other things, a delay in the recognition or loss of net sales, the write-down or destruction of existing inventory, insurance recoveries that fail to cover the full costs associated with product recalls or other claims, significant warranty, support, and repair costs, diversion of the attention of our engineering personnel from our product development efforts, and damage to our relationships with our customers. The occurrence of these problems could also result in reputational and brand damage or the delay or loss of market acceptance of our lighting products and would likely harm our business. In addition, our customers may specify quality, performance, and reliability standards that we must meet. If our products do not meet these standards, we may be required to replace or rework the products. In some cases, our products may contain undetected defects or flaws that only become evident after shipment. Even if our products meet standard specifications, our customers may attempt to use our products in applications for which they were not designed or in products that were not designed or manufactured properly, resulting in product failures and creating customer satisfaction issues.
 Some of our products use line voltages (such as 120- or 240-volts AC), which involve enhanced risk of electrical shock, injury or death in the event of a short circuit or other malfunction. Defects, integration issues or other performance problems in our lighting products could result in personal injury or financial or other damages to end-users or could damage market acceptance of our products. Our customers and end-users could also seek damages from us for their losses. A product liability claim brought against us, even if unsuccessful, would likely be time consuming and costly to defend and the adverse publicity generated by such a claim against us or others in our industry could negatively impact our reputation.
 We provide warranty periods generally ranging from one to ten years on our LED lighting products. Although we believe our reserves are appropriate, we are making projections about the future reliability of new products and technologies, and we may experience increased variability in warranty claims. Increased warranty claims could result in significant losses due to a rise in warranty expense and costs associated with customer support.
 Our industry is characterized by vigorous protection and pursuit of intellectual property rights and positions, which may result in protracted and expensive litigation. We have engaged in litigation in the past and litigation may be necessary in the future to enforce our intellectual property rights or to determine the validity and scope of the proprietary rights of others. Litigation may also be necessary to defend against claims of infringement or invalidity by others. Additionally, we could be required to defend against individuals and groups who have been purchasing intellectual property assets for the sole purpose of making claims of infringement and attempting to extract settlements from companies like ours. Litigation could delay development or sales efforts and an adverse outcome in litigation, or any similar proceedings, could subject us to significant liabilities, require us to license disputed rights from others or require us to cease marketing or using certain products or technologies. We may not be able to obtain any licenses on acceptable terms, if at all, and may attempt to redesign those products that contain allegedly infringing intellectual property, which may not be possible. We also may have to indemnify certain customers if it is determined that we have infringed upon or misappropriated another party's intellectual property. The costs of addressing any intellectual property litigation claim, including legal fees and expenses and the diversion of management resources, regardless of whether the claim is valid, could be significant and could materially harm our business, financial condition, and results of operations.
 From time to time, we have been and may in the future be subject to claims or allegations that we infringe upon or have misappropriated the intellectual property of third parties. Defending against such claims is costly and intellectual property litigation often involves complex questions of fact and law, with unpredictable results. We may be forced to acquire rights to

 such third-party intellectual property on unfavorable terms (if rights are made available at all), pay damages, modify accused products to be non-infringing, or stop selling the applicable product altogether.
 We may be subject to confidential information theft or misuse, which could harm our business and results of operations.
 We face attempts by others to gain unauthorized access to our information technology systems on which we maintain proprietary and other confidential information. Our security measures may be breached as the result of industrial or other espionage actions of outside parties, employee error, malfeasance or otherwise, and as a result, an unauthorized party may obtain access to our systems. In addition, these same risks to our information technology systems also apply to the third-party service providers' information technology systems utilized by the Company. Additionally, outside parties may attempt to access our confidential information through other means, for example by fraudulently inducing our employees to disclose confidential information. We actively seek to prevent, detect and investigate any unauthorized access, which occasionally occurs despite our best efforts. We might be unaware of any such access or unable to determine its magnitude and effects. The theft, corruption or unauthorized use or publication of our trade secrets and other confidential business information as a result of such an incident could adversely affect our competitive position and the value of our investment in research and development could be reduced. Our business could be subject to significant disruption, widespread negative publicity and a loss of customers, and we could suffer legal liabilities and monetary or other losses.
 We have international operations and are subject to risks associated with operating in international markets.
 We outsource the production of certain parts and components, as well as finished goods in certain product lines, to a small number of vendors in various locations outside of the United States, including Malaysia, Taiwan and China. Although we do not currently generate significant sales from customers outside the United States, we are targeting foreign allied navies as a potential opportunity to generate additional sales of our MMM products as well as a limited number of foreign geographic markets which we expect to expand over time.
 International business operations are subject to inherent risks, including, among others:
 • difficulty in enforcing agreements and collecting receivables through foreign legal systems;
 • unexpected changes in regulatory requirements, tariffs, and other trade barriers, restrictions or disruptions;
 • potentially adverse tax consequences;
 • localized impacts of epidemics, pandemics or other contagious outbreaks, such as the COVID-19 pandemic;
 • the burdens of compliance with the U.S. Foreign Corrupt Practices Act, similar anti-bribery laws in other countries, and a wide variety of other laws;
 • import and export license requirements and restrictions of the United States and each other country in which we operate;
 • exposure to different legal standards and reduced protection for intellectual property rights in some countries;
 • currency fluctuations and restrictions; and
 • political, social, and economic instability, including war and the threat of war, acts of terrorism, pandemics, boycotts, curtailment of trade, or other business restrictions.
 If we do not anticipate and effectively manage these risks, these factors may have a material adverse impact on our business operations.
 Our business and operations are significantly dependent on Sander Electronics, which creates material conflicts of interest and business risks.

 Our relationship with Sander Electronics, Inc., a significant shareholder and supplier controlled by our CEO Chiao Chieh (Jay) Huang, creates substantial business and governance risks. As of December 31, 2024 Sander Electronics represented 54% of our accounts payable, and we have ongoing purchasing agreements with them for TLED products and spare parts. This concentration of our supply chain with a related party creates risks regarding pricing, payment terms, and supply continuity. While we believe the terms of our transactions with Sander Electronics are commercially reasonable, the overlapping ownership and management between our companies may result in conflicts of interest that could adversely affect our business. Moreover, any deterioration in our relationship with Sander Electronics, or their inability to meet our supply requirements, could materially disrupt our operations. These risks are heightened because we have limited alternative suppliers readily available to replace Sander Electronics' production capacity. Additionally, our significant reliance on a related party supplier may draw increased regulatory scrutiny and impact our ability to demonstrate adequate internal controls over related party transactions. The materiality of this relationship could also affect our ability to obtain favorable terms from alternative suppliers.

 Our Chief Executive Officer currently serves as our Principal Financial Officer, which may impact our internal controls and increase risks related to financial reporting.

 Our Chief Executive Officer currently serves as our Principal Financial Officer and Principal Accounting Officer due to the vacancy in our Chief Financial Officer position. This dual role may result in:

 • Reduced segregation of duties in our internal control framework
 • Increased risk of errors or irregularities in financial reporting going undetected
 • Limited independent review of financial decisions and reporting processes
 • Potential delays in identifying and remediating control deficiencies
 • Challenges in maintaining adequate checks and balances in financial operations
 • Increased burden on our CEO, potentially affecting overall operational oversight

 While we have implemented additional review procedures and controls to mitigate these risks, we cannot assure that these measures will be sufficient. The concentration of these roles could materially impact the effectiveness of our internal controls over financial reporting and disclosure controls and procedures. This could result in material misstatements in our financial statements, missed filing deadlines, or other compliance issues that could adversely affect our business, financial condition, and stock price.

 Risks Associated with Legal and Regulatory Matters
 We may be subject to legal claims against us or claims by us that could have a significant impact on our resulting financial performance.
 At any given time, we may be subject to litigation or claims related to our products, intellectual property, suppliers, customers, employees, shareholders, distributors, sales representatives and sales of our assets, among other things, the disposition of which may have an adverse effect upon our business, financial condition, or results of operations. The outcome of litigation is difficult to assess or quantify. Lawsuits can result in the payment of substantial damages by defendants. If we are required to pay substantial damages and expenses as a result of these or other types of lawsuits, our business and results of operations would be adversely affected. Regardless of whether any claims against us are valid or whether we are liable, claims may be expensive to defend and may divert time and money away from our operations. Insurance may not be available at all or in sufficient amounts to cover any liabilities with respect to these or other matters. A judgment or other liability in excess of our insurance coverage for any claims could adversely affect our business and the results of our operations.
 Our business may suffer if we fail to comply with government contracting laws and regulations.
 We derive a significant portion of our revenues from direct and indirect sales to U.S., state, local and foreign governments and their respective agencies. Contracts with government customers are subject to various procurement laws and regulations, business prerequisites to qualify for such contracts, accounting procedures, intellectual property processes, and contract provisions relating to their formation, administration and performance, which may provide for various rights and remedies in favor of the governments that are not typically applicable to or found in commercial contracts. Failure to comply with these laws, regulations, or provisions in our government contracts could result in litigation, the imposition of various civil and criminal penalties, termination of contracts, forfeiture of profits, suspension of payments, or suspension from future government contracting. If our government contracts are terminated, if we are suspended from government work, or if our ability to compete for new contracts is adversely affected, our business could suffer due to, among other factors, lost sales, the costs of any government action or penalties, damages to our reputation and the inability to recover our investment in developing and marketing products for MMM use.

 If we are unable to obtain and adequately protect our intellectual property rights or are subject to claims that our products infringe on the intellectual property rights of others, our ability to commercialize our products could be substantially limited.
 We consider our technology and processes proprietary. If we are not able to adequately protect or enforce the proprietary aspects of our technology, competitors may utilize our proprietary technology. As a result, our business, financial condition, and results of operations could be adversely affected. We protect our technology through a combination of patent, copyright, trademark and trade secret laws, employee and third-party nondisclosure agreements, and similar means. Despite our efforts, other parties may attempt to disclose, obtain, or use our technologies. Our competitors may also be able to independently develop products that are substantially equivalent or superior to our products or slightly modify our products. In addition, the laws of some foreign countries do not protect our proprietary rights as fully as do the laws of the United States. As a result, we may not be able to protect our proprietary rights adequately in the United States or abroad. Furthermore, there can be no assurance that we will be issued patents for which we have applied or obtain additional patents, or that we will be able to obtain licenses to patents or other intellectual property rights of third parties that we may need to support our business in the future. The inability to obtain certain patents or rights to third-party patents and other intellectual property rights in the future could have a material adverse effect on our business.
 We may be subject to intellectual property infringement claims or other allegations by third parties, which may materially and adversely affect our business, results of operations and prospects.

 Our products are largely depending on the application of our technology. From time to time, third parties holding similar technologies and intellectual property rights, including companies, competitors, patent holding companies, customers and/or non-practicing entities, may assert intellectual property claims against us.
 Although we believe that our products do not infringe upon the intellectual property rights of third parties, we cannot be certain that our operations do not or will not infringe upon or otherwise violate intellectual property rights or other rights held by third parties, and there may be third-party intellectual property rights or other rights that are infringed by our products without our awareness. We may be from time to time in the future subject to legal proceedings and claims relating to the intellectual property rights or other rights of third parties, some even without merit. If we are forced to defend against any infringement or misappropriation claims, whether they are with or without merit, are settled out of court, or are determined in our favor, we may be required to expend significant time and financial resources on the defense of such claims. Regardless of the merits or eventual outcome, such a claim could adversely impact our brand and business. Any such assertions may require us to enter into royalty arrangement or result in us being unable to use certain intellectual property. Infringement assertions by third parties may involve patent holding companies or other patent owners who have no relevant product revenue, and therefore our own issued and pending patents may provide little or no deterrence to these patent owners in bringing intellectual property right claims against us. Furthermore, any adverse outcome of a dispute may require us to pay damages, potentially including treble damages and attorney's fees, if are found to have willfully infringed a party's intellectual property; case making, licensing or using our solutions that are alleged to infringe or misappropriate the intellectual property of others; expend additional development resources to redesign our solutions' enter into potentially unfavorable royalty or license agreements in order to obtain the right to use necessary technologies or works; and to indemnify our partners, customers and other third parties. Any of these events could adversely impact our business, results of operations and financial condition.
 If we were found to have violated the intellectual property rights of others, we may be subject to liability for our infringement activities or may be prohibited from using such intellectual property or relevant contents, and we may incur licensing or usage fees or be forced to develop alternatives of our own. As a result, our reputation may be harmed and our business and financial performance may be materially and adversely affected.
 The ability to use our net operating loss carryforwards and certain other tax attributes may be limited.
 We have significant U.S. net operating loss and tax credit carryforwards (the "Tax Attributes"). Under federal tax laws, we can carry forward and use our Tax Attributes to reduce our future U.S. taxable income and tax liabilities until such Tax Attributes expire in accordance with the Internal Revenue Code of 1986, as amended (the "IRC"). Section 382 and Section 383 of the IRC provide an annual limitation on our ability to utilize our Tax Attributes, as well as certain built-in-losses, against future U.S. taxable income in the event of a change in ownership, as defined under the IRC. Share issuances in connection with our past financing transactions or other future changes in our stock ownership, which may be beyond our control, could result in changes in ownership for purposes of the IRC. Such changes in ownership could further limit our ability to use our Tax Attributes. Accordingly, any such occurrences could adversely affect our financial condition, operating results and cash flows.

 The cost of compliance with environmental, health, safety, and other laws and regulations could adversely affect our results of operations or financial condition.
 We are subject to a broad range of environmental, health, safety, and other laws and regulations. These laws and regulations impose increasingly stringent environmental, health, and safety protection standards and permit requirements regarding, among other things, air emissions, wastewater storage, treatment, and discharges, the use and handling of hazardous or toxic materials, waste disposal practices, the remediation of environmental contamination, and working conditions for our employees. Some environmental laws, such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980, the Clean Water Act, and comparable laws in U.S. states and other jurisdictions world-wide, impose joint and several liability for the cost of environmental remediation, natural resource damages, third-party claims, and other expenses, without regard to the fault or the legality of the original conduct, on those persons who contributed to the release of a hazardous substance into the environment. We may also be affected by future laws or regulations, including those imposed in response to energy, climate change, geopolitical, or similar concerns. These laws may impact the sourcing of raw materials and the manufacture and distribution of our products and place restrictions and other requirements on the products that we can sell in certain geographical locations.
 We may be exposed to certain regulatory and financial risks related to climate change.
 Growing concerns about climate change may result in the imposition of additional regulations or restrictions to which we may
 become subject. A number of governments or governmental bodies have introduced or are contemplating regulatory changes in
 response to climate change. The outcome of new legislation or regulation in the U.S. and other jurisdictions in which we operate may result in new or additional requirements, fees or restrictions on certain activities. Compliance with these climate change initiatives may also result in additional costs to us, including, among other things, increased production costs, additional taxes, reduced emission allowances or additional restrictions on production or operations. Any adopted future climate change regulations could also negatively impact our ability to compete with companies situated in areas not subject to such limitations. We may not be able to recover the cost of compliance with new or more stringent laws and regulations, which could adversely affect our results of operations, cash flow or financial condition.

 Our net sales might be adversely impacted if our lighting systems do not meet certain certification and compliance standards.
 We are required to comply with certain legal requirements governing the materials in our products. Although we are not aware of any efforts to amend any existing legal requirements or implement new legal requirements in a manner with which we cannot comply, our net sales might be adversely affected if such an amendment or implementation were to occur.
 Moreover, although not legally required to do so, we strive to obtain certification for substantially all our products. In the United States, we seek certification on substantially all of our products from UL, ETL, or DLC. Where appropriate in jurisdictions outside the United States, we seek to obtain other similar national or regional certifications for our products. Although we believe that our broad knowledge and experience with electrical codes and safety standards have facilitated certification approvals, we cannot ensure that we will be able to obtain any such certifications for our new products or that, if certification standards are amended, we will be able to maintain such certifications for our existing products. Moreover, although we are not aware of any effort to amend any existing certification standard or implement a new certification standard in a manner that would render us unable to maintain certification for our existing products or obtain ratification for new products, our net sales might be adversely affected if such an amendment or implementation were to occur.
 We rely heavily on information technology in our operations and any material failure, weakness, interruption or breach of security could prevent us from effectively operating our business, which could have a material adverse effect on our business, financial condition, and results of operations.
 We rely heavily on our information technology systems, including our enterprise resource planning ("ERP") and customer relationship management ("CRM") software, across our operations and corporate functions, including for management of our supply chain, payment of obligations, data warehousing to support analytics, finance systems, accounting systems, and other various processes and procedures, some of which are handled by third parties, as well as lead generation, customer tracking, customer sourcing, etc. We also rely heavily on remote communication tools such as Microsoft Teams and Zoom to accommodate remote work environment and external meetings.
 Our ability to efficiently and effectively manage our business depends significantly on the reliability and capacity of these systems. Our business and results of operations may be adversely affected if we experience system usage problems. The failure of these systems to operate effectively, maintenance problems, system conversions, back-up failures, problems or lack of resources for upgrading or transitioning to new platforms or damage or interruption from circumstances beyond our control, including, without limitation, fire, natural disasters, power outages, systems failure, security breaches, cyber-attacks, viruses or

 human error could result in, among other things, transaction errors, processing inefficiencies, loss of data, inability to generate timely SEC reports, loss of sales and customers and reduced efficiency in our operations. Additionally, we and our customers could suffer financial and reputational harm if customer or Company proprietary information is compromised by such events. Remediation of such problems could result in significant unplanned capital investments and any damage or interruption could have a material adverse effect on our business, financial condition, and results of operations.
 Risks Associated with an Investment in Our Common Stock
 Our failure to comply with the continued listing requirements of Nasdaq could adversely affect the price of our common stock and its liquidity.

 We have a history of failing to comply with the continued listing requirements of Nasdaq, although we have successfully cured all the pre-existed deficiency, we may not be able to cure any deficiency timely in the future.
 On February 21, 2023, we received written notification (the "Bid Price Notification") from the Staff stating that we had not regained compliance with the Bid Price Rule and our common stock is subject to delisting from Nasdaq. On February 24, 2023, we submitted a request for a hearing before the Nasdaq Hearings Panel (the "Panel") to appeal the delisting (the "Appeal"). Under Nasdaq rules, the delisting of the Company's common stock was stayed during the pendency of the Appeal and, during such time, the Company's common stock continued to be listed on Nasdaq.

 On March 28, 2023, the Company received written notification (the "Additional Staff Determination") from the Staff stating that (i) following the Bid Price Notification, and in accordance with Listing Rule 5810(c)(2)(A), Nasdaq is no longer permitted to consider the stockholders' equity compliance plan, (ii) the Additional Staff Determination serves as an additional basis for delisting the Company's common stock from Nasdaq and (iii) the Panel will consider the Additional Staff Determination in rendering a determination regarding the continued listing of the Company's common stock on Nasdaq.

 On April 6, 2023, the Company participated in the Appeal before the Panel. The Company provided an update to the Panel on the Company's substantial progress made towards the previously submitted Plan during the three months ended March 31, 2023, and requested the Panel grant the Company an exception to (1) re-allow the previously granted exception until May 15, 2023 for the Company to regain compliance with the Minimum Stockholders' Equity Rule and (2) grant an exception allowing the Company up to 180 days following the Bid Price Notification to regain compliance with the Bid Price Rule by effecting a reverse stock split following stockholder approval at the Company's 2023 annual meeting of stockholders. On May 1, 2023, the Panel granted the Company's request (the "Panel Decision") to continue the Company's listing on Nasdaq, subject to the following conditions: (1) on or before May 15, 2023, the Company shall file with the SEC its quarterly report for the three months ended March 31, 2023 demonstrating compliance with the Minimum Stockholders' Equity Rule and (2) on or before July 7, 2023, the Company shall demonstrate compliance with the Bid Price Rule.

 On July 27, 2023, the Company received written notification from the Staff stating that the Company has regained compliance with the Bid Price Rule and the Minimum Stockholders' Equity Rule, as required by the Panel Decision. Pursuant to Nasdaq Listing Rule 5815(d)(4)(B), the Company will be subject to a mandatory panel monitor for a period of one year from July 27, 2023 (the "Monitoring Period"). If, within the Monitoring Period, the Staff finds the Company again out of compliance with the Minimum Stockholders' Equity Rule, notwithstanding Nasdaq Listing Rule 5810(c)(2), the Company will not be permitted to provide the Staff with a plan of compliance with respect to that deficiency and the Staff will not be permitted to grant additional time for the Company to regain compliance with respect to that deficiency, nor will the Company be afforded an applicable cure or compliance period pursuant to Nasdaq Listing Rule 5810(c)(3). Instead, the Staff will issue a delist determination letter and the Company will have an opportunity to request a new hearing with the initial Panel or a newly convened hearings panel if the initial Panel is unavailable. The Company will have the opportunity to respond and present to the Panel as provided by Nasdaq Listing Rule 5815(d)(4)(C). The Company's common stock may be at that time delisted from Nasdaq.

 As of the date of this Annual Report, the Company believes it has maintained compliance with the Minimum Stockholders' Equity Rule for continued listing on the Nasdaq Capital Market. To become compliant with the Bid Price Rule, the Company effected a 1-for-7 reverse stock split to increase the per share trading price of the common stock effective on 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.

 As a "thinly-traded" stock with a relatively small public float, the market price of our common stock is highly volatile and may decline regardless of our operating performance.
 Our common stock is "thinly-traded" and we have a relatively small public float, which increases volatility in the share price and makes it difficult for investors to buy or sell shares in the public market without materially affecting our share price. Throughout the fiscal year ended December 31, 2024, our market price has ranged from $1.28 to $1.35 and continues to experience significant volatility. Broad market and industry factors also may adversely affect the market price of our common stock, regardless of our actual operating performance. Factors that could cause wide fluctuations in our stock price may include, among other things:
 • actual or anticipated variations in our financial condition and operating results;
 • general economic conditions and trends;
 • addition or loss of significant customers and the timing of significant customer purchases;
 • our ability to effectively implement our growth plans, including new products, and the significance and timing of associated expenses;
 • unanticipated impairments and other changes that reduce our earnings;
 • overall conditions or trends in our industry;
 • the entry or exit of new competitors into our target markets;
 • any litigation or legal claims;
 • the terms and amount of any additional financing that we may obtain, if any;
 • unfavorable publicity;
 • additions or departures of key personnel;
 • geopolitical changes, global health concerns and macroeconomic changes;
 • changes in the estimates of our operating results or changes in recommendations by any securities or industry analysts that elect to follow our common stock;
 • market expectations following periods of rapid growth;
 • the potential impact of increased volatility due to elevated trading on the price of our stock;
 • industry-wide news events that may affect market perceptions of the value of our stock; and
 • sales of our common stock by us or our stockholders, including sales by our directors and officers.
 Because our common stock is thinly-traded, investors seeking to buy or sell a certain quantity of our shares in the public market may be unable to do so within one or more trading days and it may be difficult for stockholders to sell all of their shares in the market at any given time at prevailing prices. Any attempts to buy or sell a significant quantity of our shares could materially affect our share price. In addition, because our common stock is thinly-traded and we have a relatively small public float, the market price of our shares may be disproportionately affected by any news, commentary or rumors regarding us or our industry, regardless of the source or veracity, which could also result in increased volatility.
 In addition, in the past, following periods of volatility in the market price of a company's securities, securities litigation has often been instituted against these companies. Volatility in the market price of our shares could also increase the likelihood of regulatory scrutiny. Securities litigation, if instituted against us, or any regulatory inquiries or actions that we face could result in substantial costs, diversion of our management's attention and resources and unfavorable publicity, regardless of the merits of any claims made against us or the ultimate outcome of any such litigation or action.
 We could issue additional shares of common stock or preferred stock without stockholder approval, or new securities with terms or rights superior to those of our existing shareholders, which may adversely affect the market price of our common stock.
 We expect to require additional financing to fund future operations, including our research, development, sales and marketing activities. We are authorized to issue 50,000,000 shares of common stock of which 5,260,741 shares were issued and outstanding as of March 25, 2025, and 5,000,000 shares of preferred stock, of which 876,447 were issued and outstanding as of March 25, 2025. Our Board of Directors has the authority, without action or vote of our shareholders, to issue authorized but unissued shares of common and preferred stock subject to Nasdaq's rules. Additionally, if we raise additional funds by issuing equity securities, the percentage ownership of our current shareholders will be reduced, and, if the equity securities issued are preferred shares, the holders of the new preferred shares may have rights superior to those of our existing shareholders, which could adversely affect rights of our existing shareholders and the market price of our common stock. In addition, in order to raise additional capital or acquire businesses in the future, we may need to issue securities that are convertible or exchangeable for shares of our common or preferred stock. If we raise additional funds by issuing debt securities, the holders of those debt securities would have some rights senior to those of our existing shareholders, and the terms of these debt securities could impose restrictions on operations and create a significant interest expense for us which could have a materially adverse effect on our business. Any such issuances could be made at a price that reflects a discount to the then-current trading price of our

 common stock. These issuances could be dilutive to our existing shareholders and cause the market price of our common stock to decline.
 The exercise of outstanding warrants to purchase our common stock or the conversion of shares of our Series A Preferred Stock (as defined below) into shares of common stock may dilute the ownership interest of our investors.
 In connection with past financing activity, we have issued convertible preferred stock and warrants to purchase our common stock. The exercise of some or all of the outstanding warrants to purchase our common stock or the conversion of some or all of the outstanding Series A Preferred Stock may dilute the ownership interests of our shareholders. Any sales of our common stock issuable upon the exercise of the warrants or conversion of the Series A Preferred Stock could adversely affect prevailing market prices of our common stock. In addition, the anticipated exercise of the warrants or conversion of the Series A Preferred Stock could depress the price of our common stock, which in turn may result in the value of our common stock declining significantly.
 We have never paid dividends on our common stock, and we do not anticipate paying any cash dividends in the foreseeable future.
 We have never declared or paid dividends on our common stock, nor do we anticipate paying any cash dividends for the foreseeable future. We currently intend to retain future earnings, if any, to finance the operations and expansion of our business. Any future determination to pay cash dividends will be at the discretion of our Board of Directors and will be dependent upon our earnings, financial condition, operating results, capital requirements, a capital structure strategy and other factors as deemed necessary by our Board of Directors.
 The elimination of monetary liability against our directors under Delaware law and the existence of indemnification rights held by our directors and officers may result in substantial expenditures by the Company and may discourage lawsuits against our directors and officers.
 Our Certificate of Incorporation eliminates the personal liability of our directors to the Company and our shareholders for damages for breach of fiduciary duty as a director to the extent permissible under Delaware law. Further, our Bylaws provide that we are obligated to indemnify any of our directors or officers to the fullest extent authorized by Delaware law and, subject to certain conditions, advance the expenses incurred by any director or officer in defending any action, suit or proceeding prior to its final disposition. Those indemnification obligations could result in the Company incurring substantial expenditures to cover the cost of settlement or damage awards against our directors or officers, which we may be unable to recoup. These provisions and resultant costs may also discourage us from bringing a lawsuit against any of our current or former directors or officers for breaches of their fiduciary duties, and may similarly discourage the filing of derivative litigation by our shareholders against our directors and officers even though such actions, if successful, might otherwise benefit us or our shareholders.

 ITEM 1B. UNRESOLVED STAFF COMMENTS
 None.

 ITEM 1C. CYBERSECURITY

 Governance

 Our Board of Directors assigned specific oversight responsibility for cybersecurity to our Audit Committee, which also oversees our general risk management. The Audit Committee reviews and discusses with management our policies, practices, and risks related to information security and cybersecurity.
 Our Chief Executive Officer has primary responsibility for assessing, monitoring, and managing cybersecurity risks. To strengthen our cybersecurity posture, we engage with external consultants for regular risk assessments, penetration testing, and vulnerability analyses, allowing for proactive identification and mitigation of potential threats. We also rigorously verify the cybersecurity practices of our third-party service providers, vendors, and partners, conducting due diligence before establishing relationships and ongoing monitoring to verify compliance with our cybersecurity standards.
 Our Principal Financial Officer provides an update to the Audit Committee on any risks related to cybersecurity on a quarterly basis. Our incident response plan includes notifying the Audit Committee, and then the Board of Directors, of any material threats or incidents that arise.

 Risk Management and Strategy

 We maintain an Enterprise Risk Management ("ERM") program to identify and respond to the most critical risks to our business, including cybersecurity risks. Risks and vulnerabilities from our increased reliance on information technology systems are assessed at least annually as part of our ERM program. In response to such assessments, controls are embedded into our processes and technology by our Director of Operations & Information Technology to seek to mitigate risks to our systems and processes from cybersecurity incidents. We continuously evaluate if we have adequate controls in place utilizing a risk-based approach that aligns with the National Institute of Standards and Technology Cybersecurity Framework (NIST).
 Our information technology department diligently monitors our daily operations, overseeing the security of our computer networks through implemented systems and processes aimed at safeguarding sensitive data. Utilizing encryption and authentication technologies, we fortify our systems against unauthorized access and data loss. This proactive approach ensures the integrity and confidentiality of our data, mitigating potential risks posed by cyber threats.
 In assessing cybersecurity risks, we adopt a risk-based approach, particularly concerning third-party vendors integral to our operations. Vendors meeting specific criteria, including ownership and operation of information technology networks critical to our operations, undergo evaluation across various domains such as data security and operations management. Effective communication channels with these vendors are maintained to enable timely notification of any cybersecurity incidents that could impact our company.
 Although risks from cybersecurity threats have to date not materially affected, and we do not believe they are reasonably likely to materially affect, us, our business strategy, results of operations or financial condition, like other companies in our industry, we could, from time to time, experience threats and security incidents related to our and our third-party vendors' information systems. For more information, please see Item 1A. Risk Factors - Increased Information Technology ("IT") security threats and more sophisticated computer crime could pose a risk to our systems, networks, and services.
 Our Director of Operations & Information Technology regularly evaluates the Company's cybersecurity risk profile and leads the development of strategies to mitigate risks and address cybersecurity issues that may arise, in consultation with members of our senior management team.
 We have formal policies and procedures that address cybersecurity incident response and disaster recovery from interference with our critical applications. Our Cybersecurity Incident Response Plan provides a documented framework for responding to cybersecurity incidents in coordination across multiple departments. In the event of such an incident, our Cybersecurity Incident Response Team ("CIRT"), which is comprised of our Director of Operations & Information Technology, Director of Risk Management and representatives from Risk Management, Legal and Financial Reporting, would respond to such incident in accordance with our Cybersecurity Incident Response Plan. Any cybersecurity incident that meets certain criteria will be communicated by the CIRT to senior management and the Board in a timely manner, and will be evaluated by our Executive Management Team, comprised of certain executives, to assess the impact of the incident on the Company, considering qualitative and quantitative factors. In conducting this assessment and responding to an incident, the CIRT and Executive Management Team may utilize the services of third-party consultants.
 Cybersecurity user awareness training is mandatory for all new hires and for existing employees on an annual basis to help protect our employees and the Company against cybersecurity threats. This annual training is customized to address specific cybersecurity challenges and scenarios that we may face within the real estate investment industry. Novel cybersecurity threats to the Company that are identified by our Information Technology team are communicated to all employees by email, as needed, in an effort to promote awareness and protect the Company from cyber-attacks.

 ITEM 2. PROPERTIES
 Our principal executive offices and our manufacturing facility are located in an approximately 29,692 square foot facility in Solon, Ohio, under a lease agreement expiring on June 30, 2027. We believe this facility is adequate to support our current operations.

 ITEM 3. LEGAL PROCEEDINGS
 From time to time, we may be involved in legal proceedings arising from the normal course of business. See Note 13, "Legal Matters," to our financial statements for the year ended December 31, 2024 included in Part II, Item 8, "Financial Statements and Supplementary Data," of this Annual Report.

 ITEM 6. [RESERVED]

 ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 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.

 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.

 • 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.

 MMM products

 Total net sales

 $
 5,717

 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

 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.

 Other expenses (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 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.

 As of December 31, 2023, we had approximately $0.5 million in outstanding purchase commitments for inventory, of which the majority is expected to ship in the first quarter of 2024. We had 49% of the outstanding purchase commitments with a related party.

 Critical accounting policies and estimates
 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.

 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.

 The accompanying notes are an integral part of these 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

 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

 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):

 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

 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 1
 Unadjusted quoted prices in active markets for identical assets or liabilities.

 Level 2
 Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.

 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

 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):

 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

 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.

 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

 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

 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.

 Credit Facilities
 On August 11, 2020, we entered into two debt financing arrangements (together, the "Credit Facilities") that allowed for expanded borrowing capacity at a lower blended borrowing cost. We paid off and terminated the Credit Facilities during the year ended December 31, 2023.
 Inventory Facility with Crossroads

 The first arrangement is an inventory financing facility (the "Inventory Facility") pursuant to the Loan and Security Agreement (the "Inventory Loan Agreement") between the Company and Crossroads Financial Group, LLC, a North Carolina limited liability company ("Crossroads").

 On January 18, 2023, the Company and Crossroads entered into an amendment to the Inventory Loan Agreement (the "Crossroads Amendment") to restructure and pay down the Inventory Facility.
 The Inventory Facility was paid in full on September 24, 2023, using the interest rate of 11.16 % per annum, and the Company wrote off the difference of $ 40 thousand between the final invoice amount and the carrying value of the debt, which was recorded as interest income in 2023.

 Receivables Facility with FSW Funding

 The second Credit Facility was a receivables financing facility (the "Receivables Facility") pursuant to the Loan and Security Agreement (the "Receivables Loan Agreement") between the Company and Factors Southwest L.L.C. (d/b/a FSW Funding), an Arizona limited liability company (the "RF Lender").
 On February 7, 2023, the Company and the RF Lender agreed to terminate the Receivables Facility. All outstanding amounts under the Receivables Facility had been repaid prior to termination, and there were no prepayment fees in connection with termination.
 Promissory Notes-Related Parties
 In 2022, we entered into short-term unsecured promissory notes (the "2022 Promissory Notes") with Mei-Yun (Gina) Huang, Chiao Chieh (Jay) Huang, and Tingyu Lin. Ms. Gina Huang is a member of the Board of Directors and Mr. Jay Huang is our Chief Executive Officer ("CEO"). All the 2022 Promissory Notes were exchanged for common stock on January 17, 2023. See Note 9, "Stockholders' Equity."

 Streeterville Notes
 2022 Streeterville Note
 On April 21, 2022, we entered into a note purchase agreement (the "2022 Streeterville Note Purchase Agreement") with Streeterville Capital, LLC ("Streeterville") pursuant to which we sold and issued to Streeterville a promissory note in the principal amount of approximately $ 2.0 million (the "2022 Streeterville Note"). The 2022 Streeterville Note was issued with an original issue discount of $ 215 thousand and Streeterville paid a purchase price of approximately $ 1.8 million for the 2022 Streeterville Note, from which the Company paid $ 15 thousand to Streeterville for Streeterville's transaction expenses.

 The 2022 Streeterville Note had an original maturity date of April 21, 2024, and accrued interest at 8 % per annum, compounded daily, on the outstanding balance. On January 17, 2023, we agreed with Streeterville to restructure and pay down the 2022 Streeterville Note and extend its maturity date to December 1, 2024 (the "2022 Streeterville Note Amendment"). We agreed to make payments to reduce the outstanding amounts of the 2022 Streeterville Note of $ 500 thousand by January 20, 2023 and by $ 250 thousand by July 14, 2023. Beginning January 1, 2024, we agreed to make twelve monthly repayments of approximately $ 117 thousand each. We had the right to prepay any of the scheduled repayments at any time or from time to time without additional penalty or fees.

 On March 31, 2023, the Company entered into an Exchange Agreement (the "March 2023 Exchange Agreement") with Streeterville, pursuant to which we agreed to (i) partition from the 2022 Streeterville Note a new Promissory Note (the "March 2023 Partitioned Note") in the original principal amount of $ 250 thousand (the "March 2023 Exchange Amount"), (ii) cause the outstanding balance of the 2022 Streeterville Note to be reduced by an amount equal to the March 2023 Exchange Amount, and (iii) exchange (the "March 2023 Exchange") the March 2023 Partitioned Note for 71,715 shares of the Company's common stock. The March 2023 Exchange was priced at-the-market under the Nasdaq rules and was effected pursuant to one or more exemptions from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). There were no gross proceeds to the Company in respect of the March 2023 Exchange, provided that $ 125 thousand of the March 2023 Exchange Amount was applied toward the $ 250 thousand payment due on or before July 14, 2023 pursuant to the 2022 Streeterville Note Amendment, and $ 125 thousand was credited to satisfy the December 1, 2024 required payment.

 The total liability for the 2022 Streeterville Note, net of discount and financing fees, was $ 1.3 million at December 31, 2023.

 On January 18, 2024, the Company and Streeterville entered into a payoff letter (the "Letter") and exchange agreement ("Exchange Agreement") to pay off the 2022 Streeterville Note early. The Letter and Exchange Agreement provided that the Company made payments to reduce the outstanding obligations under the 2022 Streeterville Note of $ 1.0 million in cash by January 19, 2024 and exchange 94,440 shares of common stocks by January 23, 2024 for the remaining amount. On January 23, 2024, the 2022 Streeterville Note was terminated and the Company had no outstanding obligations to Streeterville, upon which the Company recognized a $ 187 thousand other income which is included in gain on debt extinguishment in the Condensed Consolidated Statements of Operations.
 In October 2023, an unrelated party agreed to subscribe the Company's common stock in the next round of private placement and transferred funds in the amount of $ 450 thousand. There was no restriction in use of the funds and the advanced capital contribution bore no interest. The advanced capital contribution was exchanged for common stock on March 28, 2024. See Note 9, "Stockholders' Equity."

 NOTE 8. COMMITMENTS AND CONTINGENCIES

 Purchase Commitments
 As of December 31, 2024, we had approximately $ 0.3 million in outstanding purchase commitments for inventory, of which the majority is expected to ship in the first quarter of 2025. We have 88 % of the outstanding purchase commitments with a related party.
 Settlement of Return of Slow-Moving Inventory
 On December 30, 2024, in connection with its strategy to reduce a certain quantity of low-turnover inventory, the Company entered into an agreement with the vendor, an unrelated party, to return the inventory purchased between 2021 and 2022 and transfer EnFocus registered trademarks (carry amount of $ 0). As a result, the Company will recognize a non-cash gain of approximately $ 5 thousand on the settlement of returning inventory, cancelling prepayments made with the vendor, and settlement of outstanding accounts payable with the vendor. Please see below for the related accounts as of December 31, 2024 and the gain that will be recognized on the return date, which is expected to be in the early second quarter of year 2025.

 NOTE 9. STOCKHOLDERS' EQUITY

 1-for-7 Reverse Stock Split
 At the Company's annual meeting of stockholders held on June 15, 2023, the Company's stockholders approved a reverse stock split of the outstanding shares of the Company's common stock at a ratio ranging from any whole number of at least 1-for-2 and up to 1-for-10, with the exact ratio within the foregoing range to be determined by the board of directors in its sole discretion.

 NOTE 10. INCOME TAXES
 We file income tax returns in the U.S. federal jurisdiction, as well as in various state and local jurisdictions. With few exceptions, we are no longer subject to U.S. federal, state, and local, or non-U.S. income tax examinations by tax authorities for years before 2021. Our practice is to recognize interest and penalties related to income tax matters in income tax expense when and if they become applicable. At December 31, 2024 and 2023, respectively, there were no accrued interest and penalties related to uncertain tax positions.

 In 2024 and 2023, 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 and $ 6.3 million additional federal net operating loss we recognized for the year.
 At December 31, 2024, we had federal and state net operating loss carry-forwards ("NOLs") of approximately $ 141.1 million for federal income tax purposes ($ 39.1 million for state and local income tax purposes). However, due to changes in our capital structure, approximately $ 86.8 million of the $ 141.1 million is available after the application of IRC Section 382 limitations. As a result of the Tax Cuts and Job Act of 2017 (the "Tax Act"), NOLs generated in tax years beginning after December 31, 2017

 can only offset 80% of taxable income. These NOLs can no longer be carried back, but they can be carried forward indefinitely. The $ 3.4 million and $ 6.3 million in federal net operating losses generated in 2024 and 2023 will be subject to the new limitations under the Tax Act. If not utilized, the NOLs generated prior to December 31, 2017 of $ 1.0 million will begin to expire in 2025 for federal purposes and have begun to expire for state and local purposes.
 Since we believe it is more likely than not that the benefit from NOLs will not be realized, we have provided a full valuation allowance against our deferred tax assets at December 31, 2024 and 2023, respectively. We had no net deferred tax liabilities at December 31, 2024 and 2023.

We currently operate in a single industry segment, developing and selling our LED lighting products and controls into the MMM and commercial markets.
 Operating segments are defined as components of an entity about which discrete financial information is evaluated regularly by the Company's chief operating decision maker (CODM) in deciding how to allocate resources and assess performance. The Company operates and manages its business as one business segment. The Company has a single management team that reports to the Chief Executive Officer, the Company's CODM, who comprehensively manages the entire Company. The accounting policies of the segment are the same as those described in the summary of significant accounting policies.
 When evaluating the Company's financial performance, the CODM is regularly provided with more detailed expense information than what is included in the Company's statements of operations and comprehensive loss. The CODM uses net loss, as reported in the statements of operations and comprehensive loss, in evaluating the performance of the segment. Decisions regarding resource allocation are made primarily during the annual budget planning process and reallocated as needed throughout the year. The measure of segment assets is reported on the balance sheets as total assets.

 NOTE 13. LEGAL MATTERS
 We may be the subject of threatened or pending legal actions and contingencies in the normal course of conducting our business. We provide for costs related to these matters when a loss is probable and the amount can be reasonably estimated. The effect of the outcome of these matters on our future results of operations and liquidity cannot be predicted because any such effect depends on future results of operations and the amount or timing of the resolution of such matters. While it is not possible to predict the future outcome of such matters, we believe that the ultimate resolution of such individual or aggregated matters will not have a material adverse effect on our consolidated financial position, results of operations, or cash flows. For certain types of claims, we maintain insurance coverage for personal injury and property damage, product liability and other liability coverages in amounts and with deductibles that we believe are prudent, but there can be no assurance that these coverages will be applicable or adequate to cover adverse outcomes of claims or legal proceedings against us.

 ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
 None.

 ITEM 9A. CONTROLS AND PROCEDURES
 Evaluation of disclosure controls and procedures
 We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to management, including our Chief Executive Officer, to allow for timely decisions regarding required disclosure.
 Pursuant to Rule 13a-15(b) under the Exchange Act, our management must evaluate, with the participation of our Chief Executive Officer, the effectiveness of our disclosure controls and procedures, as of December 31, 2024, the end of the period covered by this report. Management, with the participation of our current Chief Executive Officer, did evaluate the effectiveness of our disclosure controls and procedures as of the end of period covered by this report. Based on this evaluation, our Chief Executive Officer concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of December 31, 2024.
 Management's report on internal controls over financial reporting
 Management of Energy Focus, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of management, including our Chief Executive Officer, we conducted an evaluation of the effectiveness of internal control over financial reporting as of December 31, 2024 based upon criteria established in "Internal Control – Integrated Framework (2013)" issued by the Committee of Sponsoring Organizations of the Treadway Commission (the "COSO Framework").
 An effective internal control system, no matter how well designed, has inherent limitations, including the possibility of human error and circumvention or overriding of controls; therefore, it can provide only reasonable assurance with respect to reliable financial reporting. Furthermore, effectiveness of an internal control system in future periods cannot be guaranteed, because the design of any system of internal controls is based in part upon assumptions about the likelihood of future events. There can be no assurance that any control design will succeed in achieving its stated goals under all potential future conditions. Over time, certain controls may become inadequate because of changes in business conditions, or the degree of compliance with policies and procedures may deteriorate. As such, misstatements due to error or fraud may occur and not be detected.
 Based upon our evaluation under the COSO framework as of December 31, 2024, management concluded that its internal control over financial reporting was effective as of December 31, 2024.
 Changes in internal control over financial reporting
 For the fiscal year ended December 31, 2024, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
 Attestation Report of Independent Registered Public Accounting Firm
 This Annual Report does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by our independent public accounting firm pursuant to the rules of the SEC that permit us to provide only management's report.
