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, 2020 ("2020 Annual Report").

Overview

Energy Focus, Inc. engages primarily in the design, development, manufacturing, marketing and sale of energy-efficient light-emitting diode ("LED") lighting systems and controls and recently announced development of ultraviolet-C light disinfection ("UVCD") products. We develop, market and sell high quality LED lighting products and UVCD products and controls in the commercial market and military maritime market ("MMM"). Our mission is to enable our customers to run their facilities and offices with greater energy efficiency, productivity, and human health through advanced LED retrofit and UVCD solutions. Our goal is to be the LED and human-centric lighting ("HCL") technology and market leader for the most demanding applications where performance, quality, value (high quality at an affordable price), 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 and fixtures in institutional buildings for primarily indoor lighting applications with our innovative, high-quality commercial and military tubular LED ("TLED"), as well as other LED and lighting control and UVCD products. In October 2020, we announced the launch of our UVCD product portfolio which is being brought to market in 2021.

Net sales decreased 30% for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, primarily driven by a 16% decrease in military sales period-over-period, and a decrease in net sales of our commercial products of 47% for the three months ended March 31, 2021 as compared to the same prior year period. The sales cycles for the MMM is dependent on many factors, including the availability of government funding, the timing and fulfillment of U.S. Navy awards, new ship construction, diversion of funds to other government needs, and the timing of vessel maintenance schedules, and our financial results reflect volatility from fluctuations in the timing, pace and size of MMM projects. The sales cycles for our commercial target markets can range from several months to over one year and our financial results reflect volatility from the continued fluctuations in the timing, pace and size of commercial projects.

Despite continuing progress throughout 2020, operating losses increased by 82.0% in the first three months of 2021 over the first quarter of 2020. The Company's results reflect the challenges due to long and unpredictable sales cycles, unexpected delays in customer retrofit budgets and project starts, and unexpected supply chain issues exacerbated by the COVID-19 pandemic. 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 March 31, 2021.

The novel coronavirus ("COVID-19") pandemic in particular has, and may continue to have, a significant economic and business impact on our company. In the first quarter of 2021, following a slowdown throughout 2020, we have seen a continuing weakness in commercial sales as customers in the healthcare, education, and commercial and industrial sectors delayed order placements in reaction to the ongoing impacts of the COVID-19 pandemic that caused organizations to suspend or postpone lighting retrofit projects due to budget and occupancy uncertainties.

We continue to monitor the impact of the COVID-19 pandemic on our customers, suppliers and logistics providers, and to evaluate governmental actions being taken to curtail and respond to the spread of the virus. The significance and duration of the ongoing impact on us is still uncertain. Material adverse effects of the COVID-19 pandemic on market drivers, our customers, suppliers or logistics providers could significantly impact our operating results. We also plan to continue to actively follow, assess and analyze the ongoing impact of the COVID-19 pandemic and continue to adjust our organizational structure, strategies, plans and processes to respond.

Because the situation continues to evolve, we cannot reasonably estimate the ultimate impact to our business, results of operations, cash flows and financial position that the COVID-19 pandemic may have. Continuation of the COVID-19 pandemic and government actions in response thereto could cause further disruptions to our operations and the operations of our customers, suppliers and logistics partners and could significantly adversely affect our near-term and long-term revenues, earnings, liquidity and cash flows. We aim to stay agile as an organization to respond to potential or continuing weakness in the macro environment and in the meantime expand sales channels and enter new markets, such as UVCD, that might be able to provide additional growth opportunities.


                                       30

--------------------------------------------------------------------------------

It is our belief that the momentum of the efforts undertaken in 2020, as described in our 2020 Annual Report, along with the development and launch of new and innovative products, will over time result in improved sales and bottom-line performance for the Company.

We launched our EnFocus™ platform during the second quarter of 2020 and continued to receive positive feedback from existing, new, and potential new customers. 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 tubular LEDs, a far more affordable and environmentally sustainable solution compared with replacing entire lighting fixtures and incorporating additional wired or wireless communication.

In addition, in response to the COVID-19 pandemic and an anticipated increase in sanitation and hygiene demand for buildings, facilities and homes, we are developing advanced UVCD products for both consumer as well as the commercial and industrial markets. We announced the following three UVCD products in the fourth quarter of 2020: abUV™ circadian lighting and UVCD air disinfection integrated troffers controlled by the EnFocus™ platform technology; nUVo™ portable disinfection device for offices and homes; and mUVe™ autonomous robot designed for surface disinfection. These UVCD products are expected to be available in the third quarter of 2021. In the first quarter of 2021, we further announced plans for the nUVo™ Traveler personal air disinfection device and the mUVeCrewTM robotic surface disinfection service program, both expected also to be available in the second quarter of 2021.

In our MMM business, significant efforts undertaken to reduce costs in our product offerings have positioned us to be more competitive in this segment, along with improved production efficiencies. Such efforts allowed us to continue to win bids and proposals that helped grow our MMM sales throughout 2020, offsetting some of the weakness being experienced in our commercial business. In addition, during the fourth quarter of 2020, we became an approved supplier for the General Services Administration ("GSA") and our products are now listed in the GSA website for all federal and military agencies to view and order our products. While we continue to aggressively seek to increase sales of our commercial products, the MMM business offers us continued sales, in addition to validating our product quality and strengthening our brand trust in the marketplace. However, due to product mix resulting from the continued impact of the COVID-19 pandemic on a commercial sales, our current financial results are primarily driven by, and reflect volatility in, our military sales.

Meanwhile, we continue to seek additional external funding alternatives and sources to support our growth strategies, plans and initiatives. We plan to achieve profitability through developing and launching new, innovative products, such as EnFocusTM and our UVCD 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. In addition, we intend to continue to apply rigorous financial discipline in our organizational structure, business processes and policies, strategic sourcing activities and supply chain practices to help accelerate our path towards profitability.

At March 31, 2021, we had $0.5 million in cash, which excludes $0.3 million of restricted cash held, and a total of $3.4 million of debt. On August 11, 2020, we entered into two debt financing arrangements (together, the "Credit Facilities"). Total debt at March 31, 2021 included $2.7 million outstanding under our inventory financing facility (the "Inventory Facility") and $0.7 million outstanding under our receivables financing facility (the "Receivables Facility"). At March 31, 2021, we had additional availability for us to borrow of $0.2 million under the Inventory Facility and $0.5 million under the Receivables Facility. On April 20, 2021, we entered into an amendment to the Loan and Security Agreement governing the Inventory Facility (the "Inventory Loan Agreement") to increase the maximum amount that may be available to the Company from $3.0 million previously to $3.5 million, subject to the borrowing base as set forth in the Inventory Loan Agreement.

On April 27, 2021, we entered into a note purchase agreement (the "Streeterville Note Purchase Agreement") with Streeterville Capital, LLC ("Streeterville") pursuant to which the Company sold and issued to Streeterville a promissory note in the principal amount of approximately $1.7 million (the "Streeterville Note"). The Streeterville Note was issued with an original issue discount of $194 thousand and Streeterville paid a purchase price of $1.5 million for the Streeterville Note, after deduction of $15 thousand of Streeterville transaction expenses.

The Streeterville Note has a maturity date of April 27, 2023, and accrues interest at 8% per annum, compounded daily, on the outstanding balance. The Company may prepay the amounts outstanding under the Note at a premium, which is five percent during the first three months and ten percent during the thereafter. Prepayments at the reduced rate in the first three


                                       31

--------------------------------------------------------------------------------

months are limited to 50% of the outstanding balance. Beginning on the first day of the calendar month following the date that is six months after the date of purchase, Streeterville may require the Company to redeem up to $205 thousand of the Streeterville Note in any calendar month. The Company has 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 will increase the amount outstanding under the Streeterville Note by 1.5%.

Net sales

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

                                             Three months ended
                                                  March 31,
                                              2021            2020
                      Commercial        $      913          $ 1,736
                      MMM products           1,724            2,047

                      Total net sales   $    2,637          $ 3,783

Net sales of $2.6 million for the first quarter of 2021 decreased compared to first quarter net sales of $3.8 million for the three months ended March 31, 2020, driven by decreases in both commercial and MMM sales. Net sales of our commercial products decreased in the three months ended March 31, 2021 compared to the same periods of 2020, mainly reflecting (i) a decrease in sales, caused by delayed orders that have occurred mainly in the healthcare, education, commercial and industrial sectors because of the continuing macroeconomic slowdown and purchasing decisions being put on hold due to the COVID-19 pandemic, (ii) lower sales from our agency network which was also impacted by the COVID-19 pandemic, and (iii) fluctuations in the timing, pace and size of commercial projects. Net sales of our MMM products decreased mainly due to availability of government funding and the timing of shipment for orders.



                                       32

--------------------------------------------------------------------------------

Gross profit

Gross profit was $0.6 million, or 21% of net sales, for the first quarter of 2021, compared to $1.0 million, or 27.3% of net sales, for the first quarter of 2020. Gross margin for the first quarter of 2021 included favorable price and usage variances for material and labor of $0.2 million or 7% of net sales, and unfavorable inventory and warranty reserves of $0.1 million or 5.0% of net sales. Gross margin for the first quarter of 2020 included unfavorable manufacturing variances and absorption of $0.3 million, or 7.2% of net sales.

Operating expenses

Product development

Product development expenses include salaries and related expenses, contractor and consulting fees, 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 $0.7 million for the first quarter of 2021, a $0.4 million increase compared to $0.3 million for the first quarter of 2020. The increase is mainly related to payroll expense and product testing associated with the development and launch of our UVCD product portfolio.

Selling, general and administrative

Selling, general and administrative expenses were $2.2 million for the first quarter of 2021, compared to $2.0 million for the first quarter of 2020. The primary driver of the increase in selling, general and administrative expenses is an increase in payroll due to our growth initiatives that expanded our staff, primarily in sales and engineering.

Restructuring

For the three months ended March 31, 2021 and 2020, we recorded restructuring credits totaling approximately $19 thousand and $14 thousand, respectively, related to the cost and offsetting sub-lease income for the remaining lease obligations for the former New York, New York office.

Interest expense

Interest expense was $127 thousand for the first quarter of 2021, compared to interest expense of $133 thousand for the first quarter of 2020. The decrease in interest expense of $6 thousand is primarily due to more favorable terms of our current Credit Facilities compared to our prior revolving line of credit with Austin Financial Services, Inc. (the "Austin Credit Facility"). The actual cash interest paid in the first quarter of 2021 was $58 thousand compared to $67 thousand in the first quarter of 2020.

Gain on forgiveness of PPP loan

Forgiveness income of $801 thousand related to the Paycheck Protection Program ("PPP") loan taken out during 2020 was recognized during the three months ended March 31, 2021.

Income from change in fair value of warrants

A gain of $0.9 million was recognized during the three months ended March 31, 2020 for the market value change in our warrant liabilities. The income recognized in the first quarter of 2020 was a result of the revaluation of the warrant liability using the market price of the Company's common stock at March 31, 2020 versus the market price of the Company's common stock at the time of initial issuance of the warrants (January 13, 2020). No warrant liability exists at March 31, 2021, and, as such, there is no related gain or loss recorded.

Other expenses

Other expenses were $17 thousand for the first quarter of 2021, compared to other expenses of $18 thousand for the first quarter of 2020. Other expenses are mainly comprised of bank and collateral management fees.




                                       33

--------------------------------------------------------------------------------

Provision for income taxes

Due to the operating losses incurred during the three months ended March 31, 2021 and 2020, 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 March 31, 2021, our net loss was $1.6 million, compared to a net loss of $0.5 million for the three months ended March 31, 2020. The decrease is mainly due to a decrease in net sales of $1.1 million, and increases in (i) product development costs of $371 thousand; and (ii) selling, general and administrative costs of $191 thousand; all of which are offset by a decrease in cost of sales of $667 thousand. These factors are discussed in detail above.

Financial condition

At March 31, 2021, we had $0.5 million in cash, which excludes $0.3 million of restricted cash held, and a total of $3.4 million of debt, including $2.7 million outstanding under our Inventory Facility and $0.7 million outstanding under our Receivables Facility. At March 31, 2021, we had additional availability for us to borrow of $0.2 million under the Inventory Facility and $0.5 million under the Receivables Facility. We have historically incurred substantial losses, and as of March 31, 2021, we had an accumulated deficit of $132.5 million. Additionally, our sales have been concentrated among a few major customers and for the three months ended March 31, 2021, two customers accounted for approximately 61% of net sales.

As a result of the restructuring actions and initiatives described above, we have reduced our operating expenses to be more commensurate with our expected sales volumes. However, we continue to incur losses and have a substantial accumulated deficit, and substantial doubt about our ability to continue as a going concern continues to exist at March 31, 2021.

Throughout 2020, as well as the first quarter 2021, we have continued to evaluate and assess strategic options as we seek to achieve profitability. We plan to achieve profitability through growing our sales by continuing to execute 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 and launch advanced lighting and lighting control technologies and introduce impactful new products such as EnFocus™, a breakthrough lighting control platform we officially launched during the second quarter of 2020. In addition, during the last quarter of 2020, we announced newly developed UVCD products for both consumer, as well as commercial and industrial markets, that are expected to be available in the third quarter of 2021.

As described in Note 9, "Stockholders' Equity," in January 2020 we also raised approximately $2.3 million of net proceeds upon the issuance and sale of common stock and warrants (the "January 2020 Equity Offering"). Additionally, in August 2020, we entered into two revolving credit facilities, the capacity of one of which was recently increased in April 2021, and also in April 2021 we recently obtained bridge financing as described in Note 7, "Debt," which allow for expanded borrowing capacity.

The restructuring and cost cutting initiatives implemented during 2020, as well as the January 2020 Equity Offering that significantly strengthened our balance sheet, the PPP loan we obtained in April 2020 and our enhanced debt capacity due to the debt refinancing in August 2020, and increased borrowing capacity and additional bridge financing achieved in April 2021, were designed to allow us to effectively execute these strategies. However, our efforts may not occur as quickly as we envision or be successful due to the long sales cycle in our industry, the corresponding time required to ramp up sales from new products and markets into this sales cycle, the timing of introductions of additional new products, significant competition, potential sales volatility given our customer concentration, and the recent and lingering economic impact from the COVID-19 pandemic that had significantly diminished the interest and activities for lighting retrofit projects until occupancy returns to more normal levels, among other factors. 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.

                                       34

--------------------------------------------------------------------------------

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,
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 and/or conditions, such as
interest rate, restrictive covenants, conversion features, refinancing demands,
and control or revocation provisions, which are not acceptable to management or
our board of directors; and
•the current environment in the capital markets combined with our capital
constraints may prevent us from being able to obtain adequate debt financing.

If we fail to obtain the required additional financing to sustain our business before we are able to produce levels of revenue to meet our financial needs, we will need to delay, scale back or eliminate our growth plans and further reduce our operating costs and headcount, each of which would have a material adverse effect on our business, future prospects, and financial condition. A lack of additional funding could also result in our inability to continue as a going concern and force us to sell certain assets or discontinue or curtail our operations and, as a result, investors in the Company could lose their entire investment.

Considering both quantitative and qualitative information, we continue to believe that the combination of our plans to obtain additional 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, will provide us with an ability to finance our operations through the next twelve months and will mitigate the substantial doubt about our ability to continue as a going concern.

On August 17, 2020, we received a letter from the Listing Qualifications staff (the "Staff") of The Nasdaq Stock Market ("Nasdaq") notifying us that we are no longer in compliance with Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain stockholders' equity of at least $2,500,000 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 Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2020, filed on August 13, 2020, reflected that our stockholders' equity as of June 30, 2020 was $1,714,000. In addition, as of August 13, 2020, we did not meet the alternative compliance standards relating to the market value of listed securities or net income from continuing operations. On October 5, 2020, based on our timely submission of our plan to regain compliance, Nasdaq granted us an extension through February 15, 2021 to regain compliance with the Minimum Stockholders' Equity Rule, subject to our compliance with certain terms of the extension. In accordance with one part of the plan submitted to the Staff, we have successfully modified our outstanding warrants and are able to now classify the warrants within equity. At December 31, 2020, our stockholders' equity was $4,255,000. On January 20, 2021, we received a letter from the Staff notifying us that, on a conditional basis, Nasdaq has determined that we have regained compliance with the Minimum Stockholders' Equity Rule. At March 31, 2021 our stockholders' equity was $3,278,000.



                                       35

Liquidity and capital resources

Cash

At March 31, 2021, our cash balance was approximately $0.5 million, compared to approximately $1.8 million at December 31, 2020. The balance at each of March 31, 2021 and December 31, 2020 excluded restricted cash of $0.3 million for a letter of credit requirement under a lease obligation.

The following summarizes cash flows from operating, investing, and financing activities, as reflected in the Condensed Consolidated Statements of Cash Flows included in Part I, Item 1, "Financial Statements," of this Quarterly Report (in thousands):


                                                               Three months ended

     Net cash (used in) provided by operating activities   $    (2,783)     $   504

     Net cash used in investing activities                 $      (109)     $   (47)

     Net cash provided by financing activities             $     1,604      $ 2,104

Net cash (used in) provided by operating activities

Net cash used in operating activities was $2.8 million for the three months ended March 31, 2021. The net loss was $1.6 million and was adjusted for non-cash items, including depreciation and amortization, stock-based compensation, provisions for inventory, warranty, gain on forgiveness of the PPP loan and accounts receivable reserves and working capital changes. During the three months ended March 31, 2021, we generated $1.0 million in cash from accounts payable due to the timing of inventory receipts and payments, and $0.5 million through the timing of collection of accounts receivable. We used $2.0 million for inventories primarily due to the timing of inventory receipts, and we used $0.2 million due to changes in accrued and other liabilities (primarily due to a reduction of $0.1 million in accrued accounting and legal fees and $0.2 million in accrued bonuses; offset by increases of $0.1 million in accrued payroll).

Net cash provided by operating activities was $0.5 million for the three months ended March 31, 2020. The net loss incurred of $0.5 million was adjusted for non-cash items, including depreciation, stock-based compensation, change in fair value of warrant liabilities, provisions for inventory and warranty reserves, and working capital changes. The primary driver for a positive operating cash flow was the generation of $1.5 million cash from the utilization of existing inventory stock as opposed to new purchases. During the three months ended March 31, 2020, we used $0.2 million in cash for accounts payable, primarily due to the timing of inventory receipts and we used $0.2 million of prepaid and other assets due to prepaid deposits to our contract manufacturers for inventory for the new EnFocusTM platform. We generated cash of $0.4 million through the collection of accounts receivable and $0.2 million through a decrease of other liabilities, primarily related to accrued payroll and benefits and commissions. Cash generated was partially offset by an adjustment of $0.9 million for change in fair value of warrants.

Net cash used in investing activities

Net cash used in investing activities was $109 thousand for the three months ended March 31, 2021 and resulted primarily from the purchase of software and a vehicle to support production operations, as well as development of the e-commerce platform.

For the three months ended March 31, 2020, net cash used in investing activities was $47 thousand and resulted primarily from the purchase of tooling to support production operations.

Net cash provided by financing activities

Net cash provided by financing activities during the three months ended March 31, 2021 was $1.6 million, primarily related to net proceeds from the Credit Facilities of $1.1 million and proceeds from the exercise of 156,446 warrants of $0.5 million. Investors in the January 2020 Equity Offering received warrants to purchase shares of our common stock, of which

--------------------------------------------------------------------------------

warrants to purchase an aggregate of 310,860 shares remain outstanding at March 31, 2021 with a weighted average exercise price of $3.59 per share. The exercise of warrants could provide us with cash proceeds of up to $1.1 million in the aggregate.

Net cash provided by financing activities during the three months ended March 31, 2020 was $2.1 million, primarily resulting from the $2.8 million in proceeds received from the share issuance in January 2020, partially offset by $0.5 million in offering costs for the issuance and an issuance related mandatory repayment of the Iliad note of which $0.2 million was allocated against principal. At March 31, 2020, we had $1.1 million of additional availability for us to borrow under the Austin Credit Facility.

Contractual obligations

As of March 31, 2021, we had approximately $4.2 million in outstanding purchase commitments for inventory. Of this amount, approximately $1.4 million is expected to ship in the second quarter of 2021, with the balance expected to ship in the third quarter of 2021 and thereafter.

There have been no other material changes to our contractual obligations as compared to those included in our 2020 Annual Report.

Critical accounting policies

Fair value of warrant liabilities

Due to a potential cash settlement upon occurrence of a fundamental transaction within the warrant agreement, the warrants were initially classified as liabilities, as opposed to equity, and were recorded at their fair values at each balance sheet date for the first three quarters of 2020. We used the Black-Scholes valuation model to value the warrant liabilities at fair value. The fair value is estimated using the expected volatility based on our historical volatility and is determined using probability weighted average assumptions, when appropriate.

During December 2020, the warrant holders agreed to a modification of the terms of their warrants which removed the potential cash settlement option upon the occurrence of a fundamental transaction. As such, during the fourth quarter of 2020, the warrant liability was reclassified into equity and the warrants are no longer subject to re-measurement at each balance sheet date.

There have been no other material changes to our critical accounting policies as compared to those included in our 2020 Annual Report.
