We develop, market and sell high quality energy-efficient light-emitting diode (“LED”) lighting products and controls in the commercial and military maritime markets (“MMM”). Our mission is to enable our customers to run their facilities and offices with greater energy efficiency, productivity, and wellness through advanced LED retrofit solutions. Our goal is to be the retrofit technology and market leader for the most demanding applications where performance, quality and health are considered paramount. We specialize in LED lighting retrofit by replacing fluorescent, high-intensity discharge (“HID”) lighting and other types of lamps in institutional buildings for primarily indoor lighting applications with our innovative, high-quality commercial and military tubular LED (“TLED”) and other LED products and controls.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The LED lighting industry has changed dramatically over the past several years due to increasing commoditization, competition and price erosion. We have been experiencing these industry forces in both our military business since 2016 and in our commercial segment, where we once commanded significant price premiums for our flicker-free TLEDs with primarily </font><font style="font-family:inherit;font-size:10pt;">10</font><font style="font-family:inherit;font-size:10pt;">-year warranties. Since April 2019, we have focused on redesigning our products for lower costs and consolidating our supply chain for stronger purchasing power where appropriate in order to price our products more competitively. Despite these efforts, the pricing of our legacy products remains at a premium to the competitive range and we expect aggressive pricing actions and commoditization to continue to be a headwind until our more differentiated new products ramp in volume. 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 continuous, scheduled cost reductions, our strategy to combat these trends it to move up the value chain, with more innovative and differentiated products and solutions that offer greater, distinct value to our customers. Two specific examples of these more innovated and differentiated products we have recently developed include the RedCap™, our emergency backup battery integrated TLED, and EnFocus™, our new dimmable/tunable lighting and control platform that we are launching in 2020. We do believe our revamped go-to-market strategy that focuses more on direct-sales and listens to the voice of the customer has led to better and more impactful product development efforts and will eventually translate into larger addressable market and greater sales growth for us.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Since April 2019 we experienced significant change at the Company. Prior to James Tu returning as Chief Executive Officer and Chairman at the beginning of April 2019, the Company had experienced significant sales declines, operating losses and increases in its inventory. Immediately upon Mr. Tu returning to the Company, significant additional restructuring efforts were undertaken. The Company has since then replaced the entire senior management team, significantly reduced non-critical expenses, minimized the amount of inventory the company was purchasing, dramatically changed the composition of our board of directors, as well as adding very selectively to the executive team by hiring Tod Nestor as President and Chief Financial Officer at the beginning of July. The cost savings efforts undertaken included the Company implementing phased actions to reduce costs to minimize cash usage. Our initial actions included the elimination of certain positions, restructuring of the sales organization and incentive plan, flattening of the senior management team, additional operational streamlining, management compensation reductions, and outsourcing of certain functions including certain elements of supply chain and marketing. In connection with these actions, we recorded severance and related benefits charges of </font><font style="font-family:inherit;font-size:10pt;">$0.1 million</font><font style="font-family:inherit;font-size:10pt;"> during the three months ended March 31, 2019 and </font><font style="font-family:inherit;font-size:10pt;">$0.1 million</font><font style="font-family:inherit;font-size:10pt;"> during the second quarter of 2019. These additional restructuring charges primarily related to severance and related benefits charges as a result of eliminating </font><font style="font-family:inherit;font-size:10pt;">three</font><font style="font-family:inherit;font-size:10pt;"> positions during the first quarter of 2019 and </font><font style="font-family:inherit;font-size:10pt;">nine</font><font style="font-family:inherit;font-size:10pt;"> positions during the second quarter of 2019, as well as costs associated with closing our offices in San Jose, California and Taipei, Taiwan in the second quarter of 2019. With quarterly sales for the Company leveling off at its low point in the third quarter of 2019 at </font><font style="font-family:inherit;font-size:10pt;">$2.9 million</font><font style="font-family:inherit;font-size:10pt;">, we began to see the impact for our relaunch efforts and restructuring of our sales organization in the fourth quarter achieving sales of </font><font style="font-family:inherit;font-size:10pt;">$3.5 million</font><font style="font-family:inherit;font-size:10pt;">, or a quarter-over-quarter growth rate of </font><font style="font-family:inherit;font-size:10pt;">21.1%</font><font style="font-family:inherit;font-size:10pt;">. In addition, losses were mitigated through the better cost management and a sharp focus on better managing pricing and inventory decisions for the last half of 2019.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The restructuring initiative implemented in the first quarter of 2017 included a new management team, an organizational consolidation of management functions and a hybrid sales model, combining our existing historical direct sales model with sales agencies to expand our market presence throughout the United States. We closed our New York, New York, Arlington, Virginia and Rochester, Minnesota offices, reduced full-time equivalent headcount by </font><font style="font-family:inherit;font-size:10pt;">51%</font><font style="font-family:inherit;font-size:10pt;"> and significantly decreased operating expenses from 2016 levels (a net reduction of </font><font style="font-family:inherit;font-size:10pt;">$8.4 million</font><font style="font-family:inherit;font-size:10pt;">, which includes </font><font style="font-family:inherit;font-size:10pt;">$1.8 million</font><font style="font-family:inherit;font-size:10pt;"> in offsetting restructuring and impairment charges). As of December 31, 2017, we expanded our sales coverage to the entire United States through </font><font style="font-family:inherit;font-size:10pt;">six</font><font style="font-family:inherit;font-size:10pt;"> geographic regions and at the time had </font><font style="font-family:inherit;font-size:10pt;">50</font><font style="font-family:inherit;font-size:10pt;"> sales agencies, each of which had, on average, </font><font style="font-family:inherit;font-size:10pt;">10</font><font style="font-family:inherit;font-size:10pt;"> agents representing Energy Focus products. During 2017, we also implemented a strategic sales initiative to sell certain excess inventory that had previously been written-down, as required by U.S. GAAP. This initiative resulted in a net reduction of our excess inventory reserves of </font><font style="font-family:inherit;font-size:10pt;">$1.4 million</font><font style="font-family:inherit;font-size:10pt;"> in 2017.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In 2018, we made significant strides in expanding and diversifying our new product portfolio. We introduced </font><font style="font-family:inherit;font-size:10pt;">six</font><font style="font-family:inherit;font-size:10pt;"> new product families, including our commercial fixture family, our double-ended ballast bypass T8 and T5 high-output TLEDs, our Navy retrofit kit, the Invisitube ultra-low EMI TLED and our dimmable industrial downlight. Our new products, including the RedCap™ emergency battery backup tube, introduced in the fourth quarter of 2017, have gained traction, with sales of new products introduced in the past two years growing from less than one percent of total revenue in the fourth quarter of 2017 to </font><font style="font-family:inherit;font-size:10pt;">17%</font><font style="font-family:inherit;font-size:10pt;"> in the fourth quarter of 2018, the highest new product revenue in the last two years.

Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory excess and obsolescence reserve and warranty claims, the useful lives for property and equipment and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment. Actual results could differ from those estimates and such differences could be material.</font></div></div>
