PART I - FINANCIAL INFORMATION

Forward-looking statements

Unless the context otherwise requires, all references to “Energy Focus,” “we,” “us,” “our,” “our company,” or “the Company” refer to Energy Focus, Inc., a Delaware corporation, and its consolidated subsidiary for the applicable periods, considered as a single enterprise.

This Quarterly Report on Form 10-Q (this “Quarterly Report”) includes statements that express our opinions, expectations, beliefs, plans, objectives, assumptions or projections regarding future events or future results and therefore are, or may be deemed to be, “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements can generally be identified by the use of forward-looking terminology, including the terms “believes,” “estimates,” “anticipates,” “expects,” “feels,” “seeks,” “forecasts,” “projects,” “intends,” “plans,” “may,” “will,” “should,” “could” or “would” or, in each case, their negative or other variations or comparable terminology. These forward-looking statements include all matters that are not historical facts. They appear in a number of places throughout this Quarterly Report and include statements regarding our intentions, beliefs, or current expectations concerning, among other things, our results of operations, financial condition, liquidity, prospects, growth, strategies, capital expenditures, and the industry in which we operate.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. Although we base these forward-looking statements on assumptions that we believe are reasonable when made in light of information currently available to us, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and industry developments may differ materially from statements made in or suggested by the forward-looking statements contained in this Quarterly Report. In addition, even if our results of operations, financial condition and liquidity, and industry developments are consistent with the forward-looking statements contained in this Quarterly Report, those results or developments may not be indicative of results or developments in subsequent periods.

We believe that important factors that could cause our actual results to differ materially from forward-looking statements include, but are not limited to, the risks and uncertainties outlined under “Risk Factors” under Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2022 and other matters described in this Quarterly Report and our other filings with the Securities and Exchange Commission generally. Some of these factors include:

•our need for and ability to obtain additional financing in the near term, on acceptable terms or at all, to continue our operations;

•our ability to maintain compliance with the continued listing standards of The Nasdaq Stock Market LLC (“Nasdaq”);

•our ability to refinance or extend maturing debt on acceptable terms or at all;

•our ability to continue as a going concern for a reasonable period of time;

•our ability to realize synergies with our strategic investor;

•instability in the U.S. and global economies and business interruptions experienced by us, our customers and our suppliers, particularly in light of supply chain constraints and other long-term impacts of the coronavirus (“COVID-19”) pandemic;

•the competitiveness and market acceptance of our light-emitting diode (“LED”) lighting and control technologies and products;

•our ability to compete effectively against companies with lower prices or cost structures, greater resources, or more rapid development capabilities, and new competitors in our target markets;

•our ability to extend our product portfolio into new applications and end markets;

•our ability to increase demand in our targeted markets and to manage sales cycles that are difficult to predict and may span several quarters;

•the timing of large customer orders, significant expenses and fluctuations between demand and capacity as we manage inventory and invest in growth opportunities;

•our ability to successfully scale our network of sales representatives, agents, distributors and other channel partners to compete with the sales reach of larger, established competitors;

•our ability to implement plans to increase sales and control expenses;

•our reliance on a limited number of customers for a significant portion of our revenue, and our ability to maintain or grow such sales levels;

•our ability to add new customers to reduce customer concentration;

•our ability to attract and retain a new chief financial officer;

•our ability to manage the size of our workforce while continuing to attract, develop and retain qualified personnel, and to do so in a timely manner;

•our ability to diversify our reliance on a limited number of third-party suppliers and development partners, our ability to manage third-party product development and obtain critical components and finished products on acceptable terms and of acceptable quality despite ongoing global supply chain challenges, and the impact of our fluctuating demand on the stability of such suppliers;

•our ability to timely, efficiently and cost-effectively transport products from our third-party suppliers by ocean marine and other logistics channels despite global supply chain and logistics disruptions;

•the impact of any type of legal inquiry, claim or dispute;

•the macro-economic conditions, including rising interest rates and recessionary trends, in the United States and in other markets in which we operate or secure products, which could affect our ability to obtain raw materials, component parts, freight, energy, labor, and sourced finished goods in a timely and cost-effective manner;

•our dependence on military maritime customers and on the levels and timing of government funding available to such customers, as well as the funding resources of our other customers in the public sector and commercial markets;

•business interruptions resulting from geopolitical actions such as war and terrorism, natural disasters, including earthquakes, typhoons, floods and fires, or from health epidemics or pandemics or other contagious outbreaks;

•our ability to respond to new lighting and control technologies and market trends;

•our ability to fulfill our warranty obligations with safe and reliable products;

•any delays we may encounter in making new products available or fulfilling customer specifications;

•any flaws or defects in our products or in the manner in which they are used or installed;

•our ability to protect our intellectual property rights and other confidential information, and manage infringement claims by others;

•our compliance with government contracting laws and regulations, through both direct and indirect sale channels, as well as other laws, such as those relating to the environment and health and safety;

•risks inherent in international markets, such as economic and political uncertainty, changing regulatory and tax requirements and currency fluctuations, including tariffs and other potential barriers to international trade; and

•our ability to maintain effective internal controls and otherwise comply with our obligations as a public company.

In light of the foregoing, we caution you not to place undue reliance on our forward-looking statements. Any forward-looking statement that we make in this Quarterly Report speaks only as of the date of such statement, and we undertake no obligation to update any forward-looking statement or to publicly announce the results of any revision to any of those statements to reflect future events or developments, except as required by law. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless specifically expressed as such, and should only be viewed as historical data. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us.

NOTE 1. NATURE OF OPERATIONS

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 control 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 and 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.

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

Basis of presentation

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.

We have prepared the accompanying financial data for the three and nine months ended September 30, 2023 and 2022 pursuant to the rules and regulations of the United States Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The accompanying financial data and information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022 (“2022 Annual Report”). The Condensed Consolidated Balance Sheet as of December 31, 2022 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary to present fairly our Condensed Consolidated Balance Sheets as of September 30, 2023 and December 31, 2022, Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2023 and 2022, Condensed Consolidated Statements of Changes in Stockholders’ Equity for the three and nine months ended September 30, 2023 and 2022, and Condensed Consolidated Statements of Cash Flows for the three and nine months ended September 30, 2023 and 2022.

Going Concern and Nasdaq Continued Listing Requirements Compliance

Due to our financial performance as of September 30, 2023 and December 31, 2022, including net losses of $3.4 million for the nine months ended September 30, 2023 and $10.3 million for the twelve months ended December 31, 2022, and total cash used in operating activities of $2.4 million for the nine months ended September 30, 2023 and $6.7 million for the twelve months ended December 31, 2022, we determined that substantial doubt about our ability to continue as a going concern continues to exist at September 30, 2023. 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 balancing the development and implementation of an inventory reduction plan. Disruptions in global logistics networks are also impacting our lead times and ability to efficiently and cost-effectively transport products from our third-party suppliers to our facility. 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

Our Common Stock is listed on the Nasdaq Capital Market, which has as one of its continued listing requirements a minimum bid price of at least $1.00 per share. On August 23, 2022, we received a letter from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market notifying us that we were no longer in compliance with the requirement to maintain a minimum closing bid price of $1.00 per share, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”), because the closing bid price for our common stock was below the minimum $1.00 per share for 30 consecutive business days. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we were provided an initial period of 180 calendar days, or until February 20, 2023, to regain compliance with the Bid Price Rule. During the initial compliance period, our Common Stock continued to trade on the Nasdaq Capital Market, but did not satisfy the Bid Price Rule.

On November 16, 2022, we received a letter from the Staff notifying us that we were no longer in compliance with Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain stockholders’ equity of at least $2.5 million if they do not meet the alternative compliance standards relating to the market value of listed securities or net income from continuing operations (the “Minimum Stockholders’ Equity Rule”). Our Form 10-Q for the Quarterly Period Ended September 30, 2022 filed on November 10, 2022 reflected that our stockholders’ equity as of September 30, 2022 was $1.5 million. Based on our timely submission of our plan to regain compliance (the “Plan”), Nasdaq granted us an extension through May 15, 2023 to regain compliance with the Minimum Stockholders’ Equity Rule.

(Unaudited)

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 Quarterly 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.

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 reported 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 establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives of property and equipment; valuation allowance for net deferred taxes; and stock-based compensation. The Company began using estimates for its calculation of allowance for doubtful accounts receivable under Accounting Standards Codification (“ASC”) 326, Measurement of Credit Losses on

Financial Instruments (“CECL”) commencing in 2023. 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.

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 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 are accounted for on a net basis and are excluded from net sales.

The following table provides a disaggregation of product net sales for the periods presented (in thousands):


	Three months ended September 30,				Nine months ended September 30,
	2023		2022		2023		2022
Net sales:
Commercial	$	498	$	1,288	$	1,261	$	3,397
MMM products	841		476		2,063		1,908
Total net sales	$	1,339	$	1,764	$	3,324	$	5,305

Accounts Receivable

Our trade accounts receivable consists of amounts billed to and currently due from customers. Substantially all of 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 doubtful accounts receivable to provide for the estimated number of account receivables that will not be collected. The allowance is based on an assessment of forward-looking customer credit-worthiness and historical payment experience, the age of outstanding receivables, and performance guarantees to the extent applicable. Past due amounts are written off when our internal collection efforts have been unsuccessful, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. 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.

Through November 2022, we utilized a third-party account receivable insurance program with a very high credit worthy insurance company where we had the large majority of the accounts receivable arising during the policy term insured with a portion of self-retention. This third party also provided credit-worthiness ratings and metrics that significantly assisted us in evaluating the credit-worthiness of both existing and new customers. Although the insurance policy is no longer in place, all invoices issued under the previous coverage period are still covered under the policy.

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 roll rate method of valuing its reserve for trade receivables. The reserve

is based on a careful review of past delinquencies and forward-looking considerations, such as customer responsiveness. This resulted in a $2 thousand adjustment to Retained Earnings as of January 1, 2023 and charges to bad debt expense of $12 thousand in the first quarter of 2023, $3 thousand in the second quarter of 2023, and $(14) thousand in the third quarter of 2023.

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:

Geographic information

All of our long-lived fixed assets are located in the United States. For the three and nine months ended September 30, 2023 and 2022, approximately 99% 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.

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.

As a result of the net loss we incurred for the three months ended September 30, 2023, convertible securities representing approximately 25 thousand shares of common stock were excluded from the basic loss per share calculation as their inclusion would have been anti-dilutive. As a result of the net loss we incurred for the three months ended September 30, 2022, warrants and convertible securities representing approximately 31 thousand and 25 thousand shares of common stock, respectively, were excluded from the basic loss per share calculation as their inclusion would have been anti-dilutive.

As a result of the net loss we incurred for the nine months ended September 30, 2023, convertible securities 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. As a result of the net loss we incurred for the nine months ended September 30, 2022, warrants and convertible securities representing approximately 29 thousand and 25 thousand shares of common stock, respectively, were excluded from the basic loss per share calculation because their inclusion would have been anti-dilutive.

Product warranties

We warrant our commercial and MMM LED products and controls for periods generally ranging from five to ten years. 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. As warranty coverage from prior period sales expires, previous accruals are released. 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 product costs, or the warranty period expires.

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

Financial Instruments

Fair Value Measurements

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.

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; we have certain suppliers, which individually represent 10% or more of our total purchases, or whose trade accounts payable balance individually represented 10% or more of our total trade accounts payable balance, as follows:

For the three months ended September 30, 2023, sales to one U.S. Navy shipbuilders and a distributor to the U.S. Navy accounted for approximately 16% and 26% of net sales, respectively. When sales to our primary distributors for the U.S. Navy are combined with sales to shipbuilders for the U.S. Navy, total net sales of products for the U.S. Navy comprised approximately 42% of net sales for the same period. For the three months ended September 30, 2022, sales to a regional commercial lighting retrofit company accounted for approximately 32% of net sales. When sales to our primary distributors for the U.S. Navy are combined with sales to shipbuilders for the U.S. Navy, net sales of products for the U.S. Navy comprised less than 10% of net sales for the same period.

For the nine months ended September 30, 2023, sales to a U.S. Navy shipbuilder and a distributor to the Department of Defense accounted for approximately 15% and 14% of net sales, respectively. When sales to our primary distributor for the U.S. Navy are combined with sales to shipbuilders for the U.S. Navy, total net sales of products for the U.S. Navy comprised approximately 29% of net sales for the same period. For the nine months ended September 30, 2022, sales to our primary distributor for the U.S. Navy, a regional commercial lighting retrofit company, and a commercial building system provider, accounted for approximately 13%, 15%, and 10% of net sales, respectively. When sales to our primary distributor for the U.S. Navy are combined with sales to shipbuilders for the U.S. Navy, total net sales of products for the U.S. Navy comprised approximately 17% of net sales for the same period.

Two distributors for the Department of Defense and a U.S. Navy shipbuilder accounted for approximately 10%, 21% and 10% of net trade accounts receivable, respectively, at September 30, 2023. At December 31, 2022, a distributor for the Department of Defense accounted for 25% of our net trade accounts receivable and a shipbuilder for the U.S. Navy accounted for 30% of our net trade accounts receivable.

One supplier accounted for more than 10% of our total expenditures for the three and nine months ended September 30, 2023. One offshore supplier, which is related party, accounted for approximately 13% and 7%, respectively, of our total expenditures for the three and nine ended September 30, 2023. One offshore supplier accounted for approximately 17% and 18%, respectively, of our total expenditures for the three and nine ended September 30, 2022.

At September 30, 2023, two offshore suppliers accounted for approximately 48% and 22% of our trade accounts payable balance, respectively. At December 31, 2022, one offshore supplier accounted for approximately 36% of our trade accounts payable balance, respectively.

Recently adopted accounting standard

In June 2016, the Financial Accounting Standards Board issued Accounting Standard Update No. 2016-13, Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments, which significantly changes the accounting for credit losses on instruments within its scope. The new guidance introduces an approach based on expected losses to estimate credit losses on certain financial instruments, including trade receivables, and requires an entity to recognize an allowance based on its estimate of expected credit losses rather than incurred losses. For smaller reporting companies, this standard became effective for interim and annual periods starting after December 15, 2022, and has been adopted by the Company. We adopted this guidance during the first quarter of 2023, and it did not have a material impact on our consolidated financial position or results of operations.

NOTE 4. OTHER CURRENT ASSETS

Employee Retention Tax Credit

The CARES Act, which was enacted on March 27, 2020, provides an Employee Retention Tax Credit (“ERTC”) that is a refundable tax credit against certain employer taxes. The ERTC was subsequently amended by the Taxpayer Certainty and Disaster Tax Relief Act of 2020, the Consolidated Appropriation Act of 2021, and the American Rescue Plan Act of 2021, all of which amended and extended the ERTC availability and guidelines under the CARES Act. Following these amendments, we and other businesses became retroactively eligible for the ERTC, and as a result of the foregoing legislation, are eligible to claim a refundable tax credit against the employer share of Social Security taxes equal to 70% of the qualified wages paid to employees between January 1, 2021 and September 30, 2021. Qualified wages are limited to $10,000 per employee per calendar quarter in 2021 for a maximum allowable ERTC per employee of $7,000 per calendar quarter in 2021.

For purposes of the amended ERTC, an eligible employer is defined as having experienced a significant (20% or more) decline in gross receipts during each of the first three 2021 calendar quarters when compared with the same quarter in 2019 or the immediately preceding quarter to the corresponding calendar quarter in 2019. The credit is taken against the Company’s share of Social Security Tax when the Company’s payroll provider files, or subsequently amends the applicable quarterly employer tax filings.

Under the amended guidelines, we were eligible to receive the ERTC for the second and third quarters of 2021. As part of the filing of our employer tax filings for the third quarter of 2021, we applied for and received a refund of $431 thousand, and we amended our filing for the second quarter of 2021, for which we received an additional refund of approximately $445 thousand during the second quarter of 2023. This amount was recorded as a receivable in the Condensed Consolidated Balance Sheet as of December 31, 2022.

NOTE 6. 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. The Company had one finance lease on a forklift containing a bargain purchase option, which was exercised in July 2022. As of March 25, 2022, the terms of our real estate operating lease have been modified beginning July 1, 2022 and extended through 2027. In accordance with ASC 842, Leases (“ASC 842”), the related lease liability was remeasured and the right-of-use asset was adjusted for each lease at the time of modification. The present value of the lease obligations for the lease was calculated using an incremental borrowing rate of 16.96%, which was the Company’s blended borrowing rates (including interest, annual facility fees, collateral management fees, bank fees and other miscellaneous lender fees) on its revolving lines of credit with Crossroads Financial Group, LLC (as described below in Note 7, “Debt”) and Factors Southwest L.L.C. (as described below in Note 7, “Debt”). The present value of the other remaining lease obligations continues to be calculated using an incremental borrowing rate of 7.25% (which excludes the annual facility fee and other lender fees), which was the Company’s borrowing rate on its former revolving line of credit with Austin Financial Services, Inc. The weighted average remaining lease term for the operating leases is 4.0 years.

NOTE 7. DEBT

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.

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”). Borrowings under the original Inventory Facility were permitted up to the lower of (i) $3.0 million, which amount was subsequently increased to $3.5 million in April 2021, and (ii) a borrowing base determined from time to time based on the value of the Company’s eligible inventory, valued at 75% of inventory costs or 85% of the inventory net orderly liquidation value, less the availability reserves.

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 Crossroads Amendment provides that the Company make payments to reduce the outstanding obligations under the Inventory Facility of $750 thousand by January 20, 2023 and $250 thousand by February 15, 2023 (which amounts the Company has paid). The Company also agreed to make monthly payments of approximately $40 thousand towards the remaining outstanding obligations under the Inventory Facility, and to reduce the maximum amount that may be available to the Company under the Inventory Facility from $3.5 million to $500 thousand, subject to the borrowing base as set forth in the Inventory Loan Agreement.

Pursuant to the Crossroads Amendment, Crossroads and the Company also agreed to extend the Inventory Facility’s current term through December 31, 2023, while eliminating the minimum borrowing amount and unused line fees and reducing the monthly service fee to a lower, fixed amount. The Company also agreed to a slightly increased interest rate, which was more than offset by the reduction in the monthly service fees. Pursuant to the Crossroads Amendment, the interest rate on borrowings under the Inventory Facility is now a per annum rate equal to (i) the Three-Month LIBOR rate plus 5.5% or (ii) at Crossroads’ discretion, an alternative reference rate, SOFR (Secured Overnight Financing Rate), plus 6.00%. The Inventory Facility was paid in full on September 24, 2023 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.

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”). Borrowings under the Receivables Facility were permitted up to the lower of (i) $2.5 million and (ii) a borrowing base determined from time to time based on the value of the Company’s eligible accounts receivable, valued at 90% of the face value of such accounts receivable, less availability reserves, if any.

On February 7, 2023, the Company and the RF Lender agreed to terminate the Receivables Facility. All outstanding amounts under the Receivables Facility were repaid prior to termination, and there were no prepayment fees in connection with termination. The Receivables Facility was secured by substantially all of the present and future assets of the Company and was subject to an intercreditor agreement with Crossroads, which intercreditor agreement was also terminated.

Borrowings under the Inventory Facility were $1.4 million at December 31, 2022. Borrowings under the Receivables Facility were $0.1 million at December 31, 2022. These facilities are recorded in the Condensed Consolidated Balance Sheets as of December 31, 2022 as a current liability under the caption “Credit line borrowings.” Outstanding balances include $47 thousand for the Inventory Facility and $15 thousand for the Receivables Facility as of December 31, 2022.

Promissory Notes

During the third and fourth quarters of the year ended December 31, 2022, we entered into short-term unsecured promissory notes (the “2022 Promissory Notes”) with Mei Yun (Gina) Huang, Jay Huang, and Tingyu Lin. Ms. Huang is a member of the Board of Directors and Mr. Jay Huang is our Chief Executive Officer (“CEO”) and a former member of the Board of Directors in connection with the Sander Private Placement, as described below in Note 9, “Stockholders’ Equity.” The total

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 (as amended, 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 accrues 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 by $500 thousand by January 20, 2023 (which amount has been paid) and by $250 thousand by July 14, 2023 ($125 thousand of which has already been satisfied pursuant to the March 2023 Exchange Agreement (as defined below) and $125 thousand has been paid on July 12, 2023). Streeterville agreed to extend the term of the 2022 Streeterville Note through December 1, 2024, and beginning January 1, 2024, we would make twelve monthly repayments of approximately $117 thousand each. We would have the right to prepay any of the scheduled repayments at any time or from time to time without additional penalty or fees. Provided we make all payments as scheduled or earlier, the 2022 Streeterville Note will be deemed paid in full and shall automatically be deemed canceled.

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 are no gross proceeds to the Company in respect of the March 2023 Exchange, provided that $125 thousand of the March 2023 Exchange Amount will be applied toward the $250 thousand payment due on or before July 14, 2023 pursuant to the 2022 Streeterville Note Amendment, $125 thousand will be credited to satisfy the December 1, 2024 required payment and a portion of the November 1, 2024 required payment, in each case pursuant to the 2022 Streeterville Note Amendment.

The total liability for the 2022 Streeterville Note, net of discount and financing fees, was $1.3 million and $2.0 million at September 30, 2023 and December 31, 2022, respectively.

In the event our common stock is delisted from Nasdaq, the amount outstanding under the 2022 Streeterville Note will automatically increase by 15% as of the date of such delisting.

2021 Streeterville Note

On April 27, 2021, we entered into a note purchase agreement with Streeterville pursuant to which we sold and issued to Streeterville a promissory note in the principal amount of approximately $1.7 million (the “2021 Streeterville Note”). The 2021 Streeterville Note was issued with an original issue discount of $194 thousand and Streeterville paid a purchase price of $1.5 million for the 2021 Streeterville Note, after deduction of $15 thousand of Streeterville’s transaction expenses. The 2021 Streeterville Note had a maturity date of April 27, 2023, and accrued interest at 8% per annum, compounded daily, on the outstanding balance.

Beginning on November 1, 2021, Streeterville could require the Company to redeem up to $205 thousand of the 2021 Streeterville Note in any calendar month. The Company had the right on three occasions to defer all redemptions that Streeterville could otherwise require the Company to make during any calendar month. Each exercise of this deferral right by the Company increased the amount outstanding under the 2021 Streeterville Note by 1.5%. The Company exercised this right twice during the fourth quarter of 2021, once during the second quarter of 2022 and once during the third quarter of 2022. The Company and Streeterville agreed to exchange common stock, priced at-the-market, for the required redemptions in October 2022 and December 2022, totaling $305 thousand converted to equity. These exchanges satisfied the redemption notices provided by Streeterville, and following the December 2022 exchange, the 2021 Streeterville Note was paid in full. We wrote off $100 thousand in remaining original issue discount costs at that time.

NOTE 8. INCOME TAXES

As a result of the operating loss incurred during each of the three and nine months ended September 30, 2023 and 2022, and after the application of the annual limitation set forth under Section 382 of the Internal Revenue Code of 1986, as amended (the “IRC”), it was not necessary to record a provision for U.S. federal income tax.

At September 30, 2023 and December 31, 2022, we had a full valuation allowance recorded against our deferred tax assets.

The valuation allowance was recorded due to uncertainties related to our ability to realize the deferred tax assets, primarily consisting of certain net operating loss carry-forwards. The valuation allowance is based on management’s estimates of taxable income by jurisdiction and the periods over which the deferred tax assets will be recoverable.

At December 31, 2022, we had a net operating loss carry-forward of approximately $132.4 million for federal income tax purposes ($77.6 million for state and local income tax purposes). However, due to changes in our capital structure, approximately $71.0 million of the $132.4 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 “Tax Act”), 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 $9.2 million and $9.6 million in federal net operating losses generated in 2022 and 2021, 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 $37.5 million will begin to expire in 2023 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, “Income Taxes,” included under Item 8, “Financial Statements and Supplementary Data,” of our 2022 Annual Report.

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 form of the certificate of amendment (“Certificate of Amendment”) to the Certificate of Incorporation and authorized our board of directors to amend the Certificate of Incorporation to effect 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.

On June 15, 2023, our board of directors determined to set the reverse stock split at 1-for-7 (the “Split Ratio”). The Certificate of Amendment to our Certificate of Incorporation was filed with the Secretary of State of the State of Delaware on June 15, 2023, with the reverse stock split becoming effective on June 16, 2023 (the “Effective Time”). At the Effective Time, every seven shares of common stock issued and outstanding automatically combined into one validly issued, fully paid and non-assessable share of common stock. No fractional shares were issued as a result of the reverse stock split. The fractional shares were settled in cash in an amount not material to the Company. The $0.0001 par value per share of common stock and other terms of the common stock were not affected by the reverse stock split. The number of authorized shares of common stock under the Certificate of Incorporation remained unchanged at 50,000,000 shares.

The current financial statements, as well as the prior-period financial statements have been retroactively adjusted to reflect the reverse stock split.

Our outstanding shares of restricted stock and shares underlying our options and warrants entitling the holders to purchase shares of common stock have been adjusted as a result of the reverse stock split, as required by the terms of these securities. Also, the number of shares reserved for issuance under our existing 2020 Stock Incentive Plan, as amended, and our 2013 Employee Stock Purchase Plan were reduced proportionately based on the Split Ratio. Preferred shares outstanding were not affected by the reverse stock split and as such, those shares have not been adjusted.

The reverse stock split was effected solely to increase the per share trading price of the common stock to satisfy the Bid Price Rule for continued listing on Nasdaq. The common stock began trading on Nasdaq on a split-adjusted basis at the opening of trading on June 19, 2023.

March 2023 Private Placements

ITEM 2. 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 I, Item 1, “Financial Statements” of this Quarterly Report, as well as Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of our Annual Report on Form 10-K for the year ended December 31, 2022 (“2022 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 control 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 products, 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, EnFocus™, our unique dimmable/color-tunable lighting and powerline control platform that we launched in 2020, and the second generation of EnFocus™ powerline control switches and circadian lighting system. We are looking forward to the continued support and growth of our existing EnFocus™ product line which is particularly attractive for its ease of install and ease of use in spaces with transient occupation. The Company have enhanced the performance of our RedCap® product by providing a more user friendly experience in 2023. 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.

Throughout 2023, the Company 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 2022 and 2023, 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.

During 2021 and into 2022, our MMM business continued to face challenges resulting from the delayed availability of government funding and the timing of U.S. Navy awards, with several anticipated projects facing repeated and ongoing delays. This sector also maintains very long sales cycles. The timeline between bid to order can often take at least six months, and many MMM products are built-to-order with resultant lead times before orders become revenue. We continue to pursue opportunities from the U.S. Navy and the government sector to minimize such volatility. Previously in our MMM business, significant efforts undertaken to reduce costs in our product offerings have positioned us to be more competitive along with improved production efficiencies. Such efforts allowed us to continue to win bids and proposals that helped grow

our MMM sales pipeline in the second half of 2022. In May 2022, we reinvested in our MMM sales channel with a strategic hire to lead our MMM sales effort. While we continue to aggressively seek to increase sales of our commercial products, the MMM business offers us continued sales opportunities, in addition to validating our product quality and strengthening our brand trust in the marketplace. However, due to product mix impacts resulting from the continued impact of the COVID-19 pandemic on commercial sales, our current financial results are in part driven by, and reflect volatility in, our MMM sales. Notwithstanding the aforementioned challenges and results, we are pleased to see a growth during the three months ended September 30, 2023 in quotation opportunities in both MMM and commercial product lines

Meanwhile, we continue to seek additional external funding alternatives and sources to support our growth strategies, plans and initiatives. The recent strategic investments in 2023 by Sander Electronics, Inc. (“Sander”) contributed meaningful external capital, as well as presents synergistic opportunities to improve and diversify our supply chain and product offerings. We plan in part to achieve profitability through increasing sales in our innovative products such as EnFocus powerline control technology and further leveraging our unique and proprietary technology such as RedCap®, 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. We also plan to continue to develop advanced lighting and lighting control applications built upon the EnFocus platform that aim to serve the commercial market. We are also evaluating adjacent technologies including ruggedized industrial retrofit lighting applications and GaN-based power supplies and other market opportunities in energy solutions products that support sustainability in our existing channels. In addition, we intend to continue to apply rigorous financial discipline to our organizational structure, business processes and policies, strategic sourcing activities and supply chain practices to help accelerate our path towards profitability.

The EnFocus™ platform offers two immediately available product lines: EnFocus™ DM, which provides a dimmable lighting solution, and EnFocus™ DCT, which provides both a dimmable and color tunable lighting solution. EnFocus™ enables buildings to have dimmable, color tunable and circadian-ready lighting using existing wiring, without requiring laying additional data cables or any wireless communication systems, through a relatively simple upgrade with EnFocus™ switches and LED lamps, a far more secure, affordable and environmentally sustainable solution compared with replacing an entire luminaire and incorporating additional wired or wireless communication.

Despite continuing progress on cost reduction throughout 2022 and 2023, 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 continued 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 September 30, 2023.

On June 28, 2023, the Company received notices of resignation from the following four members of the Board of Directors: Jennifer Cheng, Brian Lagarto, Jeffery Parker, and Stephen Socolof. Their terms as directors would have otherwise expired at the 2024 annual meeting of stockholders of the Company. The resignations did not involve any disagreement with the Company.

On July 2, 2023, the remaining members of the Board of Directors unanimously appointed the following four new members to the Board of Directors: Kin-Fu Chen, Shou-Jang Lee, Jason Tien-Chia Tsai, and Chao-Jen Huang (“Jay Huang”). The Board of Directors affirmatively determined that, at the time of his appointment, each of the new members of the Board of Directors is an independent director under the corporate governance standards of the Nasdaq.

On August 24, 2023, the Board of Directors approved the termination of the Company’s chief executive officer and appointed Jay Huang to serve as the Company’s new chief executive officer. In line with this decision, Mr. Huang will discontinue his role as Chairman of the Board. As part of this transition, the Board has appointed Kin Fu Chen as the Chairman of the Board.

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. This foundation of cooperation enables us to more easily achieve 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.

Net sales

A further breakdown of our net sales is presented in the following table (in thousands):


	Three months ended September 30,				Nine months ended September 30,
	2023		2022		2023		2022
Commercial	$	498	$	1,288	$	1,261	$	3,397
MMM products	841		476		2,063		1,908

Total net sales	$	1,339	$	1,764	$	3,324	$	5,305

Net sales of $1.3 million for the third quarter of 2023 decreased $0.4 million, or 24%, compared to third quarter of 2022 net sales of $1.8 million, primarily driven by a decrease in commercial sales of $0.8 million, or 61%, that was partially offset by an increase in MMM sales of $0.4 million, or 77%. MMM sales increased due to larger sales orders obtained for MMM products as well as efficiency increased by the replacement of the head of MMM sales mid-year 2022. Net commercial product sales decreased in the third quarter of 2023 compared to the same period in 2022, primarily due to the lack of availability in high margin, high demand commercial products as a result of supply chain interruptions as well as the new CEO’s focus on internal processes such as cost management.

Net sales of $3.3 million for the first nine months of 2023 decreased $2.0 million, or 37%, compared to the same period in 2022, primarily driven by a 63% decrease in commercial product sales, that was partially offset by an increase in MMM product sales of 8% for the first nine months of 2023, as compared to the same period of 2022. Net commercial product sales for the first nine months of 2023 decreased as compared to the same period of 2022 due to the unavailability of high margin, high demand commercial items because of supply chain interruptions. Net sales of our MMM products increased mainly due to larger sales orders obtained for MMM products and efficiency increased by the replacement of the head of MMM sales mid-year 2022.

Gross Profit

Gross loss was $0.0 million, or (4)% of net sales, for the third quarter of 2023. This compares with gross loss of $(0.2) million, or (9)% of net sales, in the third quarter of 2022. The period-over-period increase in gross profit was driven mainly by the $0.6 million favorable impact from variable costs which included a one-time adjustment taken during the period of 2022 for a scrap write-off which was slightly offset by the $0.1 million unfavorable impact of higher fixed costs.

Gross profit was $0.1 million, or 10% of net sales, for the first nine months of 2023 compared to gross loss of $(0.1) million, or (2)% of net sales, for the first nine months of 2022. The year-over-year increase was driven by (i) a favorable $0.1 million decrease in fixed costs, or 2% of net sales, and (ii) a favorable impact of $2.1 million, or 39% of net sales, from variable cost such as change in inventory reserves which included a one-time adjustment taken during the period of 2022 for a scrap write-off.

Operating expenses

Product development

Product development expenses include salaries and related expenses, contractor and consulting fees, product development related legal fees, supplies and materials, as well as overhead, such as depreciation and facility costs. Product development costs are expensed as they are incurred.

Product development expenses were $0.1 million for the third quarter of 2023, down 61% from the third quarter of 2022. Product development expenses in the third quarter of 2023 primarily relate to salaries and related employee benefits and taxes.

Product development expenses were $0.4 million for the first nine months of 2023, a $0.8 million decrease compared to $1.2 million for the first nine months of 2022. The decrease is primarily related to payroll expense, decreased headcount, and customization of product offerings for key customers.

Selling, general and administrative

Selling, general and administrative expenses were $0.7 million for the third quarter of 2023, down 60% as compared to $1.8 million in the third quarter of 2022. The decrease in expenses from the third quarter of 2022 primarily relates to (i) a reduction of $0.6 million in payroll and payroll related expenses due to reduced headcount; (ii) a reduction of $0.1 million in trade show and other marketing expense; (iii) a reduction of $0.3 million in professional fees such as legal, recruiting, and directors; and (iv) a reduction of $0.1 million in office related expenses.

Selling, general and administrative expenses were $2.9 million for the first nine months of 2023, compared to $5.9 million for the first nine months of 2022. The decrease is primarily due to (i) decreases in payroll and payroll related expenses of $1.8 million due to reduced headcount; (ii) a reduction of $0.4 million in trade show and other marketing expense; (iii) a reduction of $0.4 million in professional fees such as legal, consulting, recruiting, and directors; and (iv) a reduction in depreciation and software expenses of $0.4 million.

Other Expense (Income)

Interest expense

Interest expense was $34 thousand for the third quarter of 2023, compared to interest expense of $235 thousand for the third quarter of 2022. The decrease in interest expense is primarily related to interest attributable to an overall reduction in principal on the Inventory Facility (as defined below) and the 2022 Streeterville Note (as defined below), lower facility fees on the Inventory Facility and elimination of the Receivables Facility (as defined below), as well as the amortization of debt costs related to the Inventory Facility. The actual cash interest paid in the third quarter of 2023 was $7 thousand compared to $84 thousand in the third quarter of 2022.

Interest expense was $226 thousand for the first nine months of 2023, compared to interest expense of $679 thousand for the first nine months of 2022. The decrease in interest expense is primarily related to interest attributable to a promissory note we sold and issued to Streeterville Capital, LLC (“Streeterville”) in the principal amount of approximately $1.7 million (the “2021 Streeterville Note”), as well as the amortization of debt costs related to the Credit Facilities (as defined below). The actual cash interest paid for each of the nine months ended September 30, 2023 and 2022 was $77 thousand and $267 thousand, respectively.

Other income and expenses

Other expenses were $7 thousand for the third quarter of 2023, compared to other expenses of $20 thousand for the third quarter of 2022. Other expenses were $28 thousand for the nine months ended September 30, 2023, compared to other expenses of $49 thousand for the nine months ended September 30, 2022. Other expenses are mainly comprised of bank and collateral management fees.

Other income for the nine months ended September 30, 2023 of $16 thousand, relates to the reversal of credit balances recorded from online retail sales which was taken to income during the second quarter of 2023. Other income of $30 thousand for the third quarter of 2022 relates to an aged customer credit balance the Company had been carrying for which the customer had not responded to various inquiries. This credit was taken to income during the first quarter of 2022.

Provision for income taxes

Due to the operating losses incurred during the three and nine months ended September 30, 2023 and 2022, and after application of the annual limitation set forth under Section 382 of the Internal Revenue Code of 1986, as amended, it was not necessary to record a provision for U.S. federal income tax or various state income taxes as income tax benefits are fully offset by a valuation allowance recorded.

Net loss

For the three months ended September 30, 2023, our net loss of $0.9 million decreased 65% from $2.7 million net loss for the three months ended September 30, 2022. The decrease is primarily due to a decrease in operating expenses in the third quarter of 2023 from the third quarter of 2022 as gross profit remained relatively flat.

For the nine months ended September 30, 2023, our net loss of $3.4 million decreased 57% from $8.0 million net loss for the nine months ended September 30, 2022. The decrease is primarily due to a decrease in operating expenses in the first nine months of 2023 from the first nine months of 2022 as gross profit remained relatively flat.

Financial condition

At September 30, 2023, we had $1.7 million in cash and a total of $1.3 million of debt, net of discounts and unamortized debt costs, related to the 2022 Streeterville Note outstanding. We have historically incurred substantial losses, and as of September 30, 2023, we had an accumulated deficit of $152.5 million. Additionally, our sales have been concentrated among a few major customers and for the nine months ended September 30, 2023, two customers accounted for approximately 29% of net sales.

In 2022 and 2023, we recommitted to building upon the transformation activities started during 2019 and 2020 that sought to stabilize and regrow our business. These efforts include the following key developments that occurred during 2022 and 2023:

•We continued development of the second generation of EnFocus™ powerline control switches and circadian lighting system for commercial markets, which as a result of supply chain challenges we now plan to launch in 2023. EnFocus™ powerline control enables buildings to have dimmable, color tunable and circadian-ready lighting using existing wiring, without requiring laying additional cables or any wireless communication systems, through a relatively simple upgrade with EnFocus™ switches and EnFocus™ LED lamps. This upgrade offers a simpler, more secure, affordable and environmentally sustainable solution compared with replacing entire luminaire fixtures and incorporating additional wired or wireless communication.

•We reinvested in our MMM sales channel with a strategic hire in the second quarter of 2022 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.

•Beginning in July 2022, we reduced our warehouse square footage, and undertook an inventory reduction project throughout 2022 focused on reducing our highly reserved commercial finished good inventory.

•The Company has aggressively re-evaluated operating expenses, and reduced its workforce significantly throughout 2022 and into 2023 to manage fixed costs.

•We continued to seek additional external funding alternatives and sources to support our growth strategies, plans and initiatives. In August 2023, we entered into a security purchase agreement, pursuant to which we raised an

aggregate gross proceeds of $1.8 million. Please refer to Note 7 and Note 9 include under Part I, “Financial Statements” of this Quarterly Report for the details.

During 2022 and into 2023, we redoubled our cost control efforts to streamline our operations by closely managing all spending done throughout the Company, while carefully investing in new products and strategies that sought to reenergize sales.

Throughout 2022 and into 2023, due to lingering economic and building occupancy impacts from the COVID-19 pandemic, we experienced continuing weakness in commercial sales as our customers in the healthcare, education, and commercial and industrial sectors put lighting retrofit projects on hold or delayed order placements. We continue to monitor the long-term impact of the COVID-19 pandemic on our customers, suppliers and logistics providers. Although the significance and duration of the ongoing impact on our customers and us is still uncertain, and the specific timing of business recovery from the long-term impacts of the COVID-19 pandemic is still difficult to predict, we remain optimistic that facility capital budgets will start unfreezing, commercial building occupancy will rise, and our growth efforts will further impact our financial performance in a positive way.

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, such as our EnFocusTM powerline control systems, 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. We also plan to continue to develop advanced lighting and lighting control applications built upon the EnFocusTM platform that aim to serve the commercial markets. 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 September 30, 2023, the June 2022 Warrants, expiring June 7, 2027, to purchase an aggregate of 384,616 shares remained outstanding, with a weighted average exercise price of $9.10 per share; warrants issued in December 2021, expiring December 16, 2026 (the “December 2021 Warrants”), to purchase an aggregate of 182,630 shares remained outstanding, with an exercise price of $24.64 per share, and warrants issued in January 2020, expiring January 13, 2025 (the “January 2020 Warrants”), to purchase an aggregate of 32,773 shares remained outstanding with a weighted average exercise price of $25.66 per share. The exercise of the remaining June 2022 Warrants, December 2021 Warrants and January 2020 Warrants outstanding could provide us with cash proceeds of up to $3.5 million, $4.5 million and $0.8 million, respectively, in the aggregate.

Net cash provided by financing activities during the nine months ended September 30, 2022 was $3.6 million, primarily related to primarily related to proceeds of $450 thousand from the 2022 Promissory Note, net proceeds of $1.8 million from the 2022 Streeterville Note and net proceeds of $3.2 million from the June 2022 Private Placement. These proceeds were offset slightly by $1.4 million in payments made against the 2021 Streeterville Note and $0.2 million in net payments made on the Credit Facilities.

Other Current Assets	OTHER CURRENT ASSETS Employee Retention Tax Credit The CARES Act, which was enacted on March 27, 2020, provides an Employee Retention Tax Credit (“ERTC”) that is a refundable tax credit against certain employer taxes. The ERTC was subsequently amended by the Taxpayer Certainty and Disaster Tax Relief Act of 2020, the Consolidated Appropriation Act of 2021, and the American Rescue Plan Act of 2021, all of which amended and extended the ERTC availability and guidelines under the CARES Act. Following these amendments, we and other businesses became retroactively eligible for the ERTC, and as a result of the foregoing legislation, are eligible to claim a refundable tax credit against the employer share of Social Security taxes equal to 70% of the qualified wages paid to employees between January 1, 2021 and September 30, 2021. Qualified wages are limited to $10,000 per employee per calendar quarter in 2021 for a maximum allowable ERTC per employee of $7,000 per calendar quarter in 2021. For purposes of the amended ERTC, an eligible employer is defined as having experienced a significant (20% or more) decline in gross receipts during each of the first three 2021 calendar quarters when compared with the same quarter in 2019 or the immediately preceding quarter to the corresponding calendar quarter in 2019. The credit is taken against the Company’s share of Social Security Tax when the Company’s payroll provider files, or subsequently amends the applicable quarterly employer tax filings. Under the amended guidelines, we were eligible to receive the ERTC for the second and third quarters of 2021. As part of the filing of our employer tax filings for the third quarter of 2021, we applied for and received a refund of $431 thousand, and we amended our filing for the second quarter of 2021, for which we received an additional refund of approximately $445 thousand during the second quarter of 2023. This amount was recorded as a receivable in the Condensed Consolidated Balance Sheet as of December 31, 2022.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES As a result of the operating loss incurred during each of the three and nine months ended September 30, 2023 and 2022, and after the application of the annual limitation set forth under Section 382 of the Internal Revenue Code of 1986, as amended (the “IRC”), it was not necessary to record a provision for U.S. federal income tax. At September 30, 2023 and December 31, 2022, we had a full valuation allowance recorded against our deferred tax assets. The valuation allowance was recorded due to uncertainties related to our ability to realize the deferred tax assets, primarily consisting of certain net operating loss carry-forwards. The valuation allowance is based on management’s estimates of taxable income by jurisdiction and the periods over which the deferred tax assets will be recoverable. At December 31, 2022, we had a net operating loss carry-forward of approximately $132.4 million for federal income tax purposes ($77.6 million for state and local income tax purposes). However, due to changes in our capital structure, approximately $71.0 million of the $132.4 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 “Tax Act”), 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 $9.2 million and $9.6 million in federal net operating losses generated in 2022 and 2021, 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 $37.5 million will begin to expire in 2023 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, “Income Taxes,” included under Item 8, “Financial Statements and Supplementary Data,” of our 2022 Annual Report.
