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&#8217; 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.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">We also generate revenue from services.

and currently due from customers. 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&#8217;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 amount of accounts receivable that will not be collected. The Company has determined that accounts receivable fall within the scope of the Current Expected Credit Losses (&#8220;CECL&#8221;) analysis in accordance with Accounting Standards Codification (&#8220;ASC&#8221;) Topic 326. 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 develop, market and sell high quality light-emitting diode (&#8220;LED&#8221;) lighting and controls products in the commercial market and military maritime market (&#8220;MMM&#8221;). In addition to our lighting portfolio, we also offer uninterruptible power supply (&#8220;UPS&#8221;) systems and other power management solutions, which have contributed meaningfully to our revenue in recent quarters and are expected to be a strategic area of continued growth.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">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 (&#8220;TLED&#8221;) products, as well as other LED and lighting control products for commercial and consumer applications. We are also evaluating additional adjacent technologies, including Gallium Nitride (&#8220;GaN&#8221;) based power supplies and other energy solution products that support sustainability in our existing channels.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The LED lighting industry has changed dramatically over the past several years due to increasing competition and price erosion. 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.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">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&#174;, our patented emergency backup battery integrated TLED, as well as our robust MMM product offering. The Company has enhanced the performance of our RedCap&#174; product by 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.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">It is our belief that our strategic initiatives undertaken in 2025 and 2026, including expansion into energy storage solutions, development of advanced Uninterruptible Power Supply (&#8220;UPS&#8221;) systems for AI data center applications, and targeted growth in the Taiwan and Japan markets, along with continued product innovation, expanded distribution capabilities, and operational efficiency, will over time result in improved sales and bottom-line performance for the Company.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">We have taken steps to strengthen our financial structure through capital increases and cost reduction measures, which we believe have improved our financial position and provided a stronger foundation for our growth initiatives. Our business expansion plans, including investments in energy storage solutions, development of advanced UPS systems for AI data center applications, and expansion into the Taiwan and Japan markets, 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. At the same time, our MMM business continues to be affected by delays in government funding, the timing of U.S. Navy awards, and long sales cycles typical of this sector, with the timeline from bid submission to order placement often exceeding six months, and many products being built-to-order, resulting in extended lead times before revenue recognition. To mitigate these factors, we continue to pursue opportunities with the U.S. Navy and other government sectors, while our cost optimization efforts have enhanced our competitiveness and may support our ability to secure new contracts and expand our sales pipeline in 2026 and beyond.</span></div><div style="height:45pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">27</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:45pt;width:100%"><div><span><br/></span></div></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">We are actively expanding our commercial product offerings, including our newly introduced UPS systems for data centers. We also continue to advance the expansion of product lines such as ESS and GaN based power supplies, while leveraging stability and opportunities within our MMM business. In 2025, 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.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">Meanwhile, we continue to seek additional external funding alternatives and sources to support our growth strategies, plans and initiatives.

The increase in net MMM products sales in the first quarter of 2026 was driven by improved demand compared to the prior year period, which was impacted by reduced military procurement activity associated with the U.S. election cycle. The increase in commercial sales was primarily attributable to improved sales volume, partially offset by inflationary pressures and market-adjusted pricing.</span></div><div id="i4338eabcdc5548fa80b9f06855e900e8_94"></div><div style="margin-bottom:10pt;margin-top:10pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">Gross Profit</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">Gross profit was $0.2&#160;million, representing 23% of net sales, for the first quarter of 2026.

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.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">In addition, on April 3, 2026, the Company entered into agreements related to a joint venture investment in Japan under which its total expected investment commitment for a 35% ownership interest is approximately $1.1&#160;million. As of May&#160;12, 2026, the Company has invested approximately $535 thousand toward this commitment, with the remaining balance of approximately $565 thousand expected to be funded during project development.

Although these estimates are based on management&#8217;s best knowledge of current events and actions that may impact us in the future, actual results may vary from the estimates.

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&#8217; 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.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">We also generate revenue from services. Service revenue primarily consists of system configuration and setup services performed in connection with customer orders. These services are typically completed at or near the time of product shipment, are distinct from the related product sales and are accounted for as separate performance obligations, and revenue is

consists of amounts billed to and currently due from customers. 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&#8217;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 amount of accounts receivable that will not be collected. The Company has determined that accounts receivable fall within the scope of the Current Expected Credit Losses (&#8220;CECL&#8221;) analysis in accordance with Accounting Standards Codification (&#8220;ASC&#8221;) Topic 326. 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. The Company has elected the practical expedient in Accounting Standards Update (&#8220;ASU&#8221;) No. 2025&#8209;05 to assume that current economic conditions as of the balance sheet date remain unchanged over the remaining life of current trade accounts receivable when developing reasonable and supportable forecasts of expected credit losses.

However, due to changes in our capital structure, approximately $86.8 million of the $141.2 million is available to offset future taxable income after the application of the limitations found under Section 382 of the Internal Revenue Code of 1986, as amended. As a result of the Tax Cuts and Jobs Act of 2017 (the &#8220;Tax Act&#8221;), net operating loss carry-forwards generated in tax years beginning after December 31, 2017 can only offset 80% of taxable income and can be carried forward indefinitely. The $1.1 million and $3.4 million in federal net operating losses generated in 2025 and 2024, respectively, will be subject to the new limitations under the Tax Act. If not utilized, the carry-forwards generated prior to December 31, 2017 of $7.3 million will begin to expire in 2026 for federal purposes and have begun to expire for state and local purposes. For a full discussion of the estimated restrictions on our utilization of net operating loss carry-forwards, please refer to Note 11, &#8220;Income Taxes,&#8221; included under Item 8, &#8220;Financial Statements and Supplementary Data,&#8221; of our 2025 Annual Report.</span></div><span></span>

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&#8217; 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.</span></div><div style="margin-bottom:10pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">We also generate revenue from services.

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable."

Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management&#x2019;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 establishment of credit losses allowance for accounts receivable, sales returns, inventory obsolescence and warranty claims, the useful lives of property and equipment, valuation allowance for deferred tax assets, and stock-based compensation. In addition, estimates and assumptions associated with the &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;determination of the fair value of financial instruments and evaluation of long-lived assets for impairment require considerable judgment.

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&#x2019; 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.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We also generate revenue from services. Service revenue primarily consists of system configuration and setup services performed in connection with customer orders. These services are typically completed at or near the time of product shipment, are distinct from the related product sales and are accounted for as separate performance obligations, and revenue is recognized at a point in time when the service is rendered.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New

billed to and currently due from customers. 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&#x2019;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 amount of accounts receivable that will not be collected. The Company has determined that accounts receivable fall within the scope of the Current Expected Credit Losses (&#x201c;CECL&#x201d;) analysis in accordance with Accounting Standards Codification (&#x201c;ASC&#x201d;) Topic 326. 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. The Company has elected the practical expedient in Accounting Standards Update (&#x201c;ASU&#x201d;) No. 2025&#x2011;05 to assume that current economic conditions as of the balance sheet date remain unchanged over the remaining life of current trade accounts receivable when developing reasonable and supportable forecasts of expected credit losses. If circumstances change, and the financial condition of our customers is adversely &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;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.

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.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Pursuant to ASC 606, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Revenue Recognition&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;, contract assets and contract liabilities as of the beginning and ending of the reporting periods must be disclosed.

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 make adjustments to the existing warranty liability when there are changes to these estimates or the underlying replacement costs, or the warranty period expires.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify"&gt;&lt;span

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.

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&#x2019; 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.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We also generate revenue from services. Service revenue primarily consists of system configuration and setup services performed in connection with customer orders. These services are typically completed at or near the time of product shipment, are distinct from the related product sales and are accounted for as separate performance obligations, and revenue is recognized at a point in time when the service is rendered.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueRecognitionPolicyTextBlock>

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&#x2019;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 amount of accounts receivable that will not be collected. The Company has determined that accounts receivable fall within the scope of the Current Expected Credit Losses (&#x201c;CECL&#x201d;) analysis in accordance with Accounting Standards Codification (&#x201c;ASC&#x201d;) Topic 326. 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. The Company has elected the practical expedient in Accounting Standards Update (&#x201c;ASU&#x201d;) No. 2025&#x2011;05 to assume that current economic conditions as of the balance sheet date remain unchanged over the remaining life of current trade accounts receivable when developing reasonable and supportable forecasts of expected credit losses. If circumstances change, and the financial condition of our customers is adversely &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;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.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our standard payment terms with customers are net 30 days to 90 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.&lt;/span&gt;&lt;/div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Pursuant to ASC 606, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Revenue Recognition&lt;/span&gt;, contract assets and contract liabilities as of the beginning and ending of the reporting periods must be disclosed.</us-gaap:TradeAndOtherAccountsReceivablePolicy>

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 make adjustments to the existing warranty liability when there are changes to these estimates or the underlying replacement costs, or the warranty period expires.&lt;/span&gt;&lt;/div&gt;</us-gaap:StandardProductWarrantyPolicy>

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.

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.

However, due to changes in our capital structure, approximately $86.8 million of the $141.2 million is available to offset future taxable income after the application of the limitations found under Section 382 of the Internal Revenue Code of 1986, as amended. As a result of the Tax Cuts and Jobs Act of 2017 (the &#x201c;Tax Act&#x201d;), net operating loss carry-forwards generated in tax years beginning after December 31, 2017 can only offset 80% of taxable income and can be carried forward indefinitely. The $1.1 million and $3.4 million in federal net operating losses generated in 2025 and 2024, respectively, will be subject to the new limitations under the Tax Act. If not utilized, the carry-forwards generated prior to December 31, 2017 of $7.3 million will begin to expire in 2026 for federal purposes and have begun to expire for state and local purposes. For a full discussion of the estimated restrictions on our utilization of net operating loss carry-forwards, please refer to Note 11, &#x201c;Income Taxes,&#x201d; included under Item 8, &#x201c;Financial Statements and Supplementary Data,&#x201d; of our 2025 Annual Report.&lt;/span&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>
