Fiscal Year


Our fiscal year is the 52- or 53-week period that ends on the Saturday closest to December 31. The 2019 and 2018 fiscal years ended on December 28, 2019 and December 29, 2018, respectively, and consisted of 52 weeks.





Overview


We provide high-performance modular memory subsystems to customers in diverse industries that require enterprise and storage class memory solutions to empower critical business decisions. We have a history of introducing disruptive new products, such as one of the first load reduced dual in-line memory modules ("LRDIMM") based on our distributed buffer architecture, which has been adopted by the industry for DDR4 LRDIMM. We were also one of the first to bring NAND flash memory ("NAND flash") to the memory channel with our NVvault non-volatile dual in-line memory modules ("NVDIMM") using software-intensive controllers and merging dynamic random access memory integrated circuits ("DRAM ICs" or "DRAM") and NAND flash to solve data bottleneck and data retention challenges

encountered in high-performance computing environments. We also offer storage class memory products called HybriDIMM to address the growing need for real-time analytics in Big Data applications, in-memory databases, high performance computing and advanced data storage solutions. We publicly demonstrated a HybriDIMM prototype in August 2016 and sampled HybriDIMM to select customers in the second half of 2017. We are continuously developing and improving upon the HybriDIMM product while exploring opportunities with strategic partners.

Due to the ground-breaking product development of our engineering teams, we have built a robust portfolio of over 130 issued and pending U.S. and foreign patents, many seminal, in the areas of hybrid memory, storage class memory, rank multiplication and load reduction. Since our inception, we have dedicated substantial resources to the development, protection and enforcement of technology innovations we believe are essential to our business. Our early pioneering work in these areas has been broadly adopted in industry-standard registered dual in-line memory modules ("RDIMM"), LRDIMM and in NVDIMM. Our objective is to continue to innovate in our field and invest further in our intellectual property portfolio, with the goal of monetizing our intellectual property through a combination of product sales and licensing, royalty or other revenue-producing arrangements, which may result from joint development or similar partnerships or defense of our patents through enforcement actions against parties we believe are infringing them.

We also resell solid state drive ("SSD"), NAND flash, DRAM products and other component products to end-customers that are not reached in the distribution models of the component manufacturers, including storage customers, appliance customers, system builders and cloud and datacenter customers.

In 2019 and 2018, we recorded total net sales of $26.1 million and $33.5 million, gross profit of $2.6 million and $2.3 million, and net loss of $12.5 million and $17.1 million, respectively. We have historically financed our operations primarily with proceeds from issuances of equity and debt securities and cash receipts from revenues, including from product sales and a non-recurring engineering ("NRE") fee from our November 2015 joint development and license agreement ("JDLA") with Samsung Electronics Co., Ltd ("Samsung"). We have also funded our operations with a revolving line of credit and term loans under a bank credit facility, and a funding arrangement for costs associated with certain of our legal proceedings against SK hynix, Inc. a South Korean memory semiconductor supplier ("SK hynix"). See "Liquidity and Capital Resources" below for more information.





Fiscal 2019-2020 Developments


Developments relating to SK hynix Proceedings

We have taken action to protect and defend our innovations by filing legal proceedings for patent infringement against SK hynix and two of its subsidiaries in the U.S. International Trade Commission ("ITC"), U.S. district court and the courts of Germany. On January 31, 2019, the court in Germany found there was no infringement of the Utility Model asserted and dismissed the case. We do not intend to appeal this ruling. In our two separate ITC actions against SK hynix, we have requested exclusion orders that direct U.S. Customs and Border Protection to stop allegedly infringing SK hynix RDIMM and LRDIMM products from entering the United States. In our U.S. district court proceedings (which are currently stayed), we are primarily seeking damages. All of our patents involved in these proceedings allegedly cover key features of RDIMM and LRDIMM products.

On January 16, 2018, the ITC issued a final determination regarding our first ITC action against SK hynix filed in September 2016, in which it concluded there was no infringement of the patents in this action and terminated the ITC's investigation related to these proceedings. We appealed this final determination to the Court of Appeals for the Federal Circuit, and oral arguments for this appeal were scheduled for December 5, 2019 at the Court of Appeals for the Federal Circuit. On December 12, 2019, the Court of Appeals for the Federal Circuit affirmed the invalidity ruling by the Patent Trial and Appeal Board ("PTAB") involving the patents in litigation at the first ITC Action and dismissed the appeal of the final determination of the first ITC Action as moot.

In our second ITC action against SK hynix, on April 12, 2018, the ITC granted SK hynix's motion for summary determination of non-infringement and terminated the investigation in its entirety. On April 23, 2018, the Company filed a petition seeking ITC review of this decision. On May 29, 2018, the ITC Commission remanded the Second ITC Action back to the ALJ to resolve the parties' claim construction disputes and continue the investigation. On June 14, 2018, the

Table of Contents

ITC extended the target date for the final determination to August 5, 2019, with a final initial determination due by April 5, 2019. Based on this extended target date, the ITC scheduled a hearing on the merits to begin on December 14, 2018 and conclude on December 21, 2018. On September 13, 2018, the ITC rescheduled the hearing on the merits to begin on January 14, 2019 and conclude on January 18, 2019. On January 29, 2019, due to the government shutdown, the ITC again rescheduled the hearing on the merits to begin on March 11, 2019 and conclude on March 15, 2019. On March 12, 2019 the ALJ postponed the trial due to reasons unrelated to the dispute between the parties. The trial recommenced on July 15, 2019 and ended on July 19, 2019. An initial determination regarding our second ITC action against SK hynix was issued on October 21, 2019. In the initial determination, the Chief Administrative Law Judge found in Netlist's favor held there was a violation of Section 337 of the Tariff Act of 1930 as amended with respect to U.S. Patent No. 9,606,907 and alternatively found there was no violation with respect to U.S. Patent No. 9,535,623. A final determination regarding our second ITC action against SK Hynix is expected to be issued on April 7, 2020.

First Amendment to TRGP Agreement

On January 23, 2020, we entered into the first amendment to the investment agreement dated May 3, 2017 with TR Global Funding V, LLC ("TRGP") ("TRGP Agreement") to amend the recovery sharing formula related to claims against SK hynix for alleged infringement of our patents. TRGP Agreement generally provides that TRGP will directly fund the costs incurred by us or on our behalf in connection with our first ITC action and our U.S. district court proceedings against SK hynix.

Amendment to SVB Credit Agreement

On February 27, 2020, we entered into an amendment to a credit agreement dated October 31, 2009 with Silicon Valley Bank ("SVB") (the "SVB Credit Agreement") to extend the maturity date of the borrowings under the SVB Credit Agreement from March 30, 2020 to April 30, 2021.

2019 Lincoln Park Purchase Agreement

On June 24, 2019, we entered into a purchase agreement (the "2019 Purchase Agreement") with Lincoln Park Capital Fund, LLC ("Lincoln Park"), pursuant to which we have the right to sell to Lincoln Park up to an aggregate of $10 million in shares of our common stock over the 36-month term of the 2019 Purchase Agreement subject to the conditions and limitations set forth in the 2019 Purchase Agreement. As consideration for entering into the 2019 Purchase Agreement, we issued to Lincoln Park 818,420 shares of our common stock as initial commitment shares in a noncash transaction on June 24, 2019 and will issue up to 818,420 additional shares of our common stock as additional commitment shares on a pro rata basis in connection with any additional purchases. We will not receive any cash proceeds from the issuance of these additional commitment shares.

During 2019, Lincoln Park purchased an aggregate of 19,044,762 shares of our common stock for a net purchase price of $6.4 million. In connection with the purchases, the Company issued to Lincoln Park an aggregate of 523,633 shares of our common stock as additional commitment shares in noncash transactions.

2020 Lincoln Park Purchase Agreement

On March 5, 2020, we entered into a purchase agreement (the "2020 Purchase Agreement") with Lincoln Park, pursuant to which we have the right to sell to Lincoln Park up to an aggregate of $20 million in shares of our common stock over the 36-month term of the 2020 Purchase Agreement subject to the conditions and limitations set forth in the 2020 Purchase Agreement. As consideration for entering into the 2020 Purchase Agreement, we issued to Lincoln Park 1,529,052 shares of our common stock as initial commitment shares in a noncash transaction on March 6, 2020 and will issue up to 917,431 additional shares of our common stock as additional commitment shares on a pro rata basis in connection with any additional purchases. We will not receive any cash proceeds from the issuance of these additional commitment shares.

Based on the number of shares of our common stock authorized as of the date of the 2020 Purchase Agreement, unless the trading price of our common stock increases substantially, we will not be able to utilize all of the capacity of



                                       37

the equity line financing unless we increase the total number of our authorized shares, which would require the approval of a majority of our outstanding shares voting at a duly convened stockholder meeting.

Completion of Iliad Note Conversion

During 2019, Iliad Research and Trading, L.P. ("Iliad") fully-converted the outstanding principal and accrued interest on the Iliad Note to shares of our common stock as follows: (1) $1.9 million of the outstanding principal and accrued interest on the unsecured convertible promissory note we issued to Iliad on August 27, 2018 ("Iliad Note") to 7,778,270 shares of our common stock at the Redemption Conversion Price, as defined in a Securities Purchase Agreement dated August 27, 2018 ("Iliad Purchase Agreement") and (2) $0.5 million of the outstanding principal and accrued interest on the Iliad Note to 1,388,890 shares of our common stock at the Lender Conversion Price, as defined in the Iliad Purchase Agreement. As a result of these conversions, as of December 28, 2019, there were no outstanding principal and accrued interest on the Iliad Note.

Factors Affecting Our Performance





Trends in Net Sales

We have been substantially dependent on sales of single products or product categories. For instance, we have historically been dependent on sales of our memory subsystem products, and in recent periods, we have been dependent on our resales of component products. Demand for any of these products could increase or decrease at any time for a number of reasons, including new customer qualifications, changing customer requirements or preferences, product obsolescence, introduction of more advanced or otherwise superior products by us or our competitors, the ability of our customers to obtain these products or substitute products from alternate sources, customers increasing or reducing their need for these products generally, or a variety of other factors. We have no long-term agreements or other commitments with respect to sales of any of these products. As a result, any fluctuations in demand for these products from us would impact our sale levels and net sales.

In past years, we have experienced declines in demand for and sales of our memory subsystem products, and these declines could continue or intensify in the future. Contrastingly, we have recently experienced marked increases in component product resales. Because the cost of the component products we purchase for resale is added to our cost of sales for these products, our gross margin on resales of component products is generally significantly lower than our gross margin on sales of our memory subsystem products. As a result, increases or decreases in component product resales as a percentage of our total sales have a significant impact on our gross margins.

Next-generation HybriDIMM and some of our other next-generation products may require additional time and capital investments in order to commercialize, and our development and commercialization strategies for these products, including, for instance, our work with JEDEC to facilitate broad industry adoption of this new technology, may not be successful. Our ability to obtain customer or market acceptance of these next-generation products will materially impact our net product sales and gross profits, as well as our ability to recoup our investments in developing these products.

Customer Composition and Concentrations

Our target markets are characterized by a limited number of large companies, and consolidation in one or more of these target markets may further increase this concentration. As a result, sales to small numbers of customers have historically represented a substantial portion of our net sales, and we expect this concentration to continue. Additionally, the composition of major customers and their respective contributions to our net sales have fluctuated and will likely continue to fluctuate from period to period as our existing and prospective customers progress through the life cycle of the products they produce and sell and experience resulting fluctuations in their product demand. We believe our performance depends in significant part on our ability to establish and maintain relationships with and effect substantial sales to our large customers. We do not have long-term agreements with any of our customers and, as result, any or all of them could decide at any time to increase, accelerate, decrease, delay or discontinue their purchase of our products or the component products we resell. These fluctuations in customer demand and concentrations could significantly impact our net sales.



                                       38

  Table of Contents



Product Sale Prices


The prices customers pay for the products we sell can fluctuate due to many factors, including, among others, competitive conditions in our key customer markets, changes in customer requirements or preferences, volatility in the market prices for SSDs, DRAM ICs, NAND flash and other component products, and changes in manufacturing efficiencies or capacities. Our industry has historically been characterized by declines in average sale prices. If sale price declines are not offset by corresponding decreases in costs or increases in sales volume or sales of products with higher margins, these sale price declines could have a material adverse effect on our operating results.

Once our prices with a customer are negotiated, we are generally unable to revise pricing with that customer until our next regularly scheduled price adjustment. As a result, if market prices for essential components increase, we generally cannot pass the price increases through to our customers for products purchased under an existing purchase order. Consequently, we are exposed to the risks associated with the volatility of prices for these components and our cost of sales could increase and our gross margins could decrease in the event of sudden price increases. Alternatively, if there are declines in the prices of these components, we may be required to reduce our selling prices for subsequent purchase orders, which may result in a decline in our net sales.

In addition, because a large percentage of our sales are often from sales to a small number of customers, these customers may exert pressure on us to make concessions in the prices at which we sell products to them. These sale price concessions could have a material effect our net sales.





Component Product Supply


Our ability to fulfill customer orders for our memory subsystem products or the component products we resell is dependent on a sufficient supply of SSDs, DRAM ICs, NAND flash and other component products. We have no long-term supply contracts for any of these component products. There are a relatively small number of suppliers of these components, and we typically purchase from only a subset of these suppliers.

From time to time, shortages in SSDs, DRAM ICs and NAND flash have required some suppliers to limit the supply of these components. In the past, we have experienced supply chain disruptions and shortages of DRAM and NAND flash required to create certain of our memory subsystem products, and we have been forced to procure the component products we resell from other suppliers to the extent sufficient product is not available from Samsung to meet customer demand or in the event of other Samsung supply issues. Supply shortages can occur at any time and for a variety of reasons, including, among others, spikes in customer demand that cannot be satisfied by our suppliers, any problems that arise with the supplier's manufacturing operations or facilities that cause disruptions or delays, or any failure by the supplier to comply with the terms of its supply arrangements with us. If we are not able to obtain components in the amounts needed, on a timely basis and at commercially reasonable prices, we may lose customers due to order delivery interruptions or failures, which could impact our net sales, and we may experience increases in our cost of sales if we are forced to procure components from alternative suppliers and are not able to negotiate favorable terms with these suppliers. For example, with respect to Samsung, any inability to obtain sufficient component products from Samsung could increase our cost of sales for component product resales because we may not be able to make arrangements with other suppliers on financial and other terms comparable to those we have negotiated with Samsung under the JDLA. As described above, we may or may not be able to pass any such cost increases through to our customers, in which case they could materially adversely impact our results by increasing our cost of sales without a corresponding increase in our net sales.





Product Demand Forecasting



Because of the short-term nature of the commitments by many of our customers and the short turnaround times that apply to most orders, as well as our customers' ability to cancel or defer purchase orders for any reason, we are required to make component procurement decisions based on forecasts of customer demand for the products we sell.





                                       39

  Table of Contents

Our production expense and component purchase levels are to a large extent fixed in the short term. As a result, we may be unable to adjust spending on a timely basis to compensate for any unexpected shortfall in customer orders. If we overestimate customer demand, we may have excess component or finished goods inventory, which may not be able to be used in other products or resold and may become obsolete before any such use or resale. If there is a subsequent decline in the prices of components, the value of our inventory would fall and we may be required to write-down the value of our component inventory, which may result in a significant increase in our cost of sales and decrease in our gross margins. In the past, we have had to write-down inventory due to obsolescence, excess quantities and declines in market value below our costs. As a result, any significant shortfall of customer orders in relation to our expectations could hurt our operating results, cash flows and financial condition.

Conversely, any rapid increases in demand by our customers could strain our resources. If we underestimate customer demand, we may not have sufficient inventory of necessary components on hand to meet that demand and we may need to try to procure additional quantities, which may not be available or may only be available at high prices or on otherwise unfavorable terms. We also may not have sufficient manufacturing capacity at any given time to meet any demands for rapid increases in production of our memory subsystem products. Any shortages of inventory or manufacturing capacity could lead to delays in the delivery of products, which may reduce our net sales.

In addition, if our product demand forecasts are inaccurate, we may understate or overstate the provision required for excess and obsolete inventory. If our inventories are determined to be overvalued, we would be required to recognize additional expense in our cost of sales at the time of the determination. Conversely, if our inventories are determined to be undervalued, we may have over-reported our costs of sales in previous periods and would be required to recognize additional gross profit at the time the inventories are sold.

Intellectual Property Protection, Enforcement and Monetization

We dedicate substantial resources to developing technology innovations we believe are essential to our business. We intend to pursue monetization avenues for our intellectual property portfolio, potentially including licensing, royalty or other revenue-producing arrangements. However, we have not generated any such revenue stream from our intellectual property to date. If we are not successful in monetizing our intellectual property portfolio, we may never recoup our investments of time, capital and other resources in the development, maintenance, defense and enforcement of this portfolio, which could materially adversely affect our results of operations.

We also dedicate substantial resources to protecting and enforcing our intellectual property rights, including with patent infringement proceedings we file against third parties and defense of our patents against challenges made by way of reexamination and review proceedings at relevant government agencies. We expect these activities to continue for the foreseeable future, with no guarantee that any ongoing or future patent protection or litigation activities will be successful. We are also subject to litigation based on claims that we have infringed the intellectual property rights of others. Any litigation, regardless of its outcome, is inherently uncertain, involves a significant dedication of resources, including time and capital, and diverts management's attention from our other activities. As a result, any current or future infringement claims or patent challenges by or against third parties, whether or not eventually decided in our favor or settled, could materially adversely affect our business, financial condition and results of operations. Additionally, the outcome of pending or future litigation and related patent reviews and reexaminations, as well as any delay in their resolution, could affect our ability to continue to sell our products, protect against competition in the current and expected markets for our products or license or otherwise monetize our intellectual property rights in the future.

Business Risks and Uncertainties

Our business, financial condition and prospects are exposed to a number of risks and uncertainties. See the discussion in Part I, Item 1A. Risk Factors of this Form 10-K for more information.

Net Sales,  Cost of Sales, and Gross Profit



The following table presents net sales, cost of sales and gross profit for 2019 and 2018 (dollars in thousands):






                   2019        2018      Change
Net sales        $ 26,103    $ 33,529     (22%)
Cost of sales      23,533      31,228     (25%)
Gross profit     $  2,570    $  2,301       12%
Gross margin         9.8%        6.9%




Net Sales


Net sales include resales of certain component products, including SSDs and DRAM products, and sales of our high-performance memory subsystems. In 2019 and 2018, resales of component products represented 77% and 75% of net sales, respectively.

Net sales decreased 22% or $7.4 million during 2019 compared to 2018 primarily as a result of a $4.2 million decrease in the resales of SODIMM and RDIMM products, a $3.1 million decrease in sales of our Specialty SODIMM and RDIMM products and a $0.3 million decrease in sales of our very low profile ("VLP") memory subsystem products, partially offset by a $0.3 million increase in sales of SSDs.

Our product sales were impacted by fluctuating customer concentrations. During 2019, there were no customers who accounted for more than 10% of our net sales, while during 2018, there was one customer that accounted for more than 10% of our net sales. During 2019 and 2018, our four largest customers accounted for an aggregate of 23% and 38% of our net sales, respectively.

Cost of Sales and Gross Profit

Cost of sales decreased in 2019 compared to 2018 due primarily to lower SODIMM and RDIMM product sales. Gross profit increased in 2019 compared to 2018 due primarily to higher gross profits on our SSD products and the resales of SODIMM and RDIMM products, partially offset by lower gross profit on the sales of our Specialty SODIMM



                                       41

  Table of Contents

and RDIMM products. Year-over-year gross margin (or gross profit as a percentage of net sales) increased during 2019 due primarily to the increased margin on the SODIMM and RDIMM products and NAND products.





Operating Expenses

$ 14,060    $ 18,673




Research and Development



Research and development expenses decreased in 2019 compared to 2018 primarily as a result of a $0.5 million decrease in headcount-related expenses and depreciation expenses. This is due to the decline in demand for our memory subsystem products and increase in component product resales in recent years.

Intellectual Property Legal Fees

Intellectual property legal fees consist of legal fees incurred for patent filings, protection and enforcement. Although we expect intellectual property legal fees to generally increase over time as we continue to protect, defend and enforce and seek to expand our patent portfolio, these increases may not be linear but may occur in lump sums depending on the due dates of patent filings and their associated fees and the arrangements we may make with our legal advisors in connection with enforcement proceedings, which may include fee arrangements such as with TRGP or contingent fee arrangements in which we would pay these legal advisors on a scaled percentage of any negotiated fees, settlements or judgments awarded to us based on if, how and when the fees, settlements or judgments are obtained. See Note 8 "Commitments and Contingencies" to the consolidated financial statements in Part IV, Item 15 of this Form 10-K for further discussion.

Pursuant to the terms of the TRGP Agreement, the legal expenses we incurred for our first action against SK hynix at the ITC and our U.S. district court proceedings that were paid directly by TRGP were excluded in their entirety from our financial statements. As of December 28, 2019, accumulated deficit excluded $1.7 million and $10.2 million of such legal expenses incurred in 2018 and 2017, respectively. In 2019, we did not have such legal expenses incurred that were excluded from our financial statements. TPGP does not fund the legal expenses incurred for our second ITC action and our proceedings in international courts. Any settlement or other cash proceeds we may recover in the future in connection with our first ITC action against SK hynix that were funded by TRGP would be reduced by the aggregate amount of legal expenses we excluded as a result of TRGP's payment of these expenses, plus the premium amount due to TRGP under the terms of the TRGP Agreement at the time of any such recovery. As a result, so long as the TRGP Agreement remains in effect, we expect our intellectual property legal fees may show different trends. Additionally, we expect our intellectual property legal fees would be significantly higher in the period in which a recovery from the SK hynix proceedings covered by the TRGP Agreement, if any, occurs.

Intellectual property legal fees decreased in 2019 as compared to 2018 due primarily to lower legal expenses incurred to defend our patent portfolio internationally, including the costs incurred for our second ITC action and inter partes review of our patents before the U.S. Patent and Trademark Office.

Selling, General and Administrative

SG&A expenses increased in 2019 compared to 2018 primarily as a result of a $1.1 million increase in payroll and related compensation expenses and travel expenses related to employment of additional sales and marketing personnel to support new business revenue, partially offset by a $0.3 million decrease in professional fees and public company expenses.

Interest expense, net, in 2019 and 2018 consisted primarily of interest expense on a revolving line of credit under the SVB Credit Agreement, the $15 million senior secured convertible note issued to Samsung Venture Investment Co. ("SVIC") ("SVIC Note") in November 2015 and the Iliad Note issued in August 2018. Interest expense also includes the accretion of debt discounts and amortization of debt issuance costs on the SVIC Note and Iliad Note. The increase in 2019 compared to 2018 was primarily driven by the full year of interest expense, accretion of debt discount and amortization of debt issuance costs in 2019 related to the Iliad Note issued in August 2018.

Liquidity and Capital Resources

Our primary sources of cash are historically proceeds from issuances of equity and debt securities and receipts from revenues, including from product sales and the NRE fee from our JDLA with Samsung. We have also funded our operations with a revolving line of credit under a bank credit facility, a funding arrangement for costs associated with certain of our legal proceedings against SK hynix and, to a lesser extent, equipment leasing arrangements.

The following table presents selected financial information as of and for the years ended December 28, 2019 and December 29, 2018 (in thousands):

Cash Flows from Operating Activities

Net cash used in operating activities for 2019 was primarily a result of a net loss of $12.5 million, adjusted for non-cash charges of $2.6 million, which primarily consisted of stock-based compensation, non-cash lease expense, amortization of debt discounts and interest accrued on our convertible notes. These non-cash activities are offset by net cash outflows from changes in working capital balances of $1.8 million driven predominantly by a $0.8 million increase in accounts receivable due to higher sales in the fourth quarter of 2019, a $0.6 million increase in inventories due to higher purchases to support increased sales, and a $0.6 million decrease in accrued expenses and other current liabilities primarily from the decrease in operating lease liabilities, partially offset by a decrease of $0.5 million in prepaid expenses and other current liabilities.

Net cash used in operating activities for 2018 was primarily a result of a net loss of $17.1 million, adjusted for non-cash charges of $1.7 million. These non-cash charges primarily consisted of stock-based compensation, interest accrued on convertible notes, depreciation and amortization and amortization of debt discounts. The net loss is offset by net cash inflows from changes in working capital balance of $4.8 million driven predominantly from an increase in accounts payable due to an increase in legal fees.

Cash Flows from Investing Activities

Net cash used in investing activities for 2019 and 2018 was primarily the result of purchases of property and equipment during the periods.

Cash Flows from Financing Activities

Net cash provided by financing activities for 2019 primarily consisted of $6.4 million in proceeds from issuance of common stock to Lincoln Park and $0.7 million in net borrowings under the SVB Credit Agreement, partially offset by $0.4 million in payment of note payable to finance insurance policies.

Net cash provided by financing activities for 2018 primarily consisted of $9.2 million in net proceeds from the 2018 Offering, $5.8 million in net proceeds from the ATM Program, $2.1 million from the issuance of the Iliad Note, $0.8 million from the issuance of common stock to a trust controlled by our President, Chief Executive Officer and Chairman of the Board, and $0.3 million in net borrowings under the SVB Credit Agreement, partially offset by $0.3 million in payment of note payable to finance insurance.





Capital Resources


2019 Lincoln Park Purchase Agreement

On June 24, 2019, we entered into the 2019 Purchase Agreement with Lincoln Park, pursuant to which we have the right to sell to Lincoln Park up to an aggregate of $10 million in shares of our common stock over the 36-month term of the 2019 Purchase Agreement subject to the conditions and limitations set forth in the 2019 Purchase Agreement. As of December 28, 2019, an aggregate of $3.6 million in shares of our common stock was available for purchases over the remaining term under the 2019 Purchase Agreement.

2020 Lincoln Park Purchase Agreement

On March 5, 2020, we entered into the 2020 Purchase Agreement with Lincoln Park, pursuant to which we have the right to sell to Lincoln Park up to an aggregate of $20 million in shares of our common stock over the 36-month term of the 2020 Purchase Agreement subject to the conditions and limitations set forth in the 2020 Purchase Agreement.





2018 Offering


On September 12, 2018, we entered into a Securities Purchase Agreement with certain investors, pursuant to which we issued and sold to the investors in the 2018 Offering an aggregate of 22,222,220 shares of our common stock and warrants to purchase up to an aggregate of 11,111,110 shares of our common stock at a per share purchase price of $0.45 per share. The 2018 Offering closed on September 14, 2018. The net proceeds to us from the 2018 Offering were $9.2 million, after deducting placement agent fees and offering costs paid by us.





Iliad Note


On August 27, 2018, we entered into the Iliad Purchase Agreement with Iliad, pursuant to which we issued a $2.3 million Iliad Note with an original debt discount of $0.2 million. The Iliad Note bore interest at an annual rate of 8% and would mature on August 27, 2020, unless earlier repurchased, redeemed or converted in accordance with its terms. During 2019, Iliad fully converted the outstanding principal and accrued interest on the Iliad Note to shares of our common stock as follows: (1) $1.9 million of the outstanding principal and accrued interest on the Iliad Note to 7,778,270 shares of our common stock at the Redemption Conversion Price and (2) $0.5 million of the outstanding principal and accrued interest on the Iliad Note to 1,388,890 shares of our common stock at the Lender Conversion Price. As a result, as of December 28, 2019, there were no outstanding principal and accrued interest on the Iliad Note.

Share Purchase Agreement



On May 17, 2018, we entered into a Board approved arm's length Share Purchase Agreement with a trust controlled by C.K. Hong, our President, Chief Executive Officer and Chairman of the Board, pursuant to which we sold to the trust 5,405,405 shares of our common stock at a price per share of $0.148 (the closing price of our common stock as of the signing of the agreement). The net proceeds received by us were $0.8 million.





TRGP Agreement


On May 3, 2017, we entered into the TRGP Agreement, which generally provided that TRGP will directly fund the costs incurred by us or on our behalf in connection with our first ITC action and our U.S. district court proceedings against SK hynix. During 2018 and 2017, TRGP directly paid $1.7 million and $10.2 million on our behalf incurred in connection with these proceedings. On January 23, 2020, we entered into an amendment to the TRGP Agreement to alter the recovery sharing formula related to claims against SK hynix.





SVB Credit Agreement


On October 31, 2009, we entered into an SVB Credit Agreement, which provides for a revolving line of credit of up to $5.0 million. The borrowing base is limited to 85% of eligible accounts receivable (increased from 80% as of August 29, 2018), subject to certain adjustments as set forth in the SVB Credit Agreement. As of December 28, 2019, the borrowings under the SVB Credit Agreement bear interest at the Wall Street Journal "prime rate" plus 2.75% per annum and mature on March 30, 2020. On February 27, 2020, the SVB Credit Agreement was amended to extend the maturity date to April 30, 2021.

As of December 28, 2019, the outstanding borrowings under the SVB Credit Agreement were $3.0 million with additional borrowing availability of $0.2 million. During 2019, we made net borrowings of $0.7 million under the SVB Credit Agreement.





SVIC Note


On November 18, 2015, we issued the SVIC Note, which has an original principal amount of $15.0 million, accrues interest at a rate of 2.0% per year, is due and payable in full on December 31, 2021, and is convertible into shares of our common stock at a conversion price of $1.25 per share, subject to certain adjustments, on the maturity date of the SVIC Note. Partial proceeds from the SVIC Note were used to repay a former loan from a different lender.

Sufficiency of Cash Balances and Potential Sources of Additional Capital

We believe our existing balance of cash and cash equivalents together with cash receipts from revenues, borrowing availability under the SVB Credit Agreement, the equity financing available under the 2020 and 2019 Lincoln Park Purchase Agreements, funds raised through the debt and equity offerings and taking into account cash expected to be used in our operations, will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our capital requirements will depend on many factors, including, among others: the acceptance of, and demand for, our products; our levels of net product sales and any other revenues we may receive, including NRE, license, royalty or other fees; the extent and timing of any investments in developing, marketing and launching new or enhanced products or technologies; the costs of developing, improving and maintaining our internal design, testing and manufacturing processes; the costs associated with defending and enforcing our intellectual property rights; and the nature and timing of acquisitions and other strategic transactions in which we participate, if any.

Although we expect to rely in the near term on our existing cash and cash equivalents balance and our primary source of cash described above, our estimates of our operating revenues and expenses and working capital requirements could be incorrect, and we may use our cash resources faster than we anticipate. Further, some or all of our ongoing or planned investments may not be successful and could result in further losses. Until we can generate sufficient revenues to finance our cash requirements from our operations, which we may never do, we may need to increase our liquidity and capital resources by one or more measures, which may include, among others, reducing operating expenses,



                                       45

  Table of Contents

restructuring our balance sheet by negotiating with creditors and vendors, entering into strategic partnerships or alliances, raising additional financing through the issuance of debt, equity or convertible securities or pursuing alternative sources of capital, such as through asset or technology sales or licenses or other alternative financing arrangements. We may not be able to obtain capital when needed, on terms acceptable to us or at all and may have the need to seek the authorization of additional shares from our stockholders, which could be costly, time-consuming and unsuccessful.

Inadequate working capital would have a material adverse effect on our business and operations and could cause us to fail to execute our business plan, fail to take advantage of future opportunities or fail to respond to competitive pressures or customer requirements. A lack of sufficient funding may also require us to significantly modify our business model and/or reduce or cease our operations, which could include implementing cost-cutting measures or delaying, scaling back or eliminating some or all of our ongoing and planned investments in corporate infrastructure, research and development projects, business development initiatives and sales and marketing activities, among other activities. Modification of our business model and operations could result in an impairment of assets, the effects of which cannot be determined. Furthermore, if we continue to issue equity or convertible debt securities to raise additional funds, our existing stockholders may experience significant dilution, and the new equity or debt securities may have rights, preferences and privileges that are superior to those of our existing stockholders. If we incur additional debt, it may increase our leverage relative to our earnings or to our equity capitalization or have other material consequences. If we pursue asset or technology sales or licenses or other alternative financing arrangements to obtain additional capital, our operational capacity may be limited and any revenue streams or business plans that are dependent on the sold or licensed assets may be reduced or eliminated. Moreover, we may incur substantial costs in pursuing any future capital-raising transactions, including investment banking, legal and accounting fees, printing and distribution expenses and other similar costs, which would reduce the benefit of the capital received from the transaction.

Off-Balance Sheet Arrangements.

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditure or capital resources that is material to investors.





Critical Accounting Policies


The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make judgments, assumptions and estimates that affect the amounts reported. Note 2 "Summary of Significant Accounting Policies" of the notes to consolidated financial statements in Part IV, Item 15 of this Form 10-K describes the significant accounting policies and methods used in the preparation of our consolidated financial statements. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates, and such differences may be material. We have reviewed our critical accounting policies and estimates with the audit committee of our board of directors.

Allowance for Doubtful Accounts

We perform credit evaluations of our customers' financial condition and limit the amount of credit extended to our customers as deemed necessary, but generally require no collateral. We evaluate the collectability of accounts receivable based on a combination of factors. In cases where we are aware of circumstances that may impair a specific customer's ability to meet its financial obligations subsequent to the original sale, we will record an allowance against amounts due, and thereby reduce the net recognized receivable to the amount we reasonably believe will be collected. For accounts receivable from our international customers, we purchase comprehensive foreign credit insurance to mitigate risks related to the collectability. For all other customers, we record allowances for doubtful accounts based primarily on the length of time the receivables are past due based on the terms of the originating transaction, the current business environment, and our historical experience. Uncollectible accounts are charged against the allowance for doubtful accounts when all cost-effective commercial means of collection have been exhausted. Generally, our credit



                                       46

Table of Contents

losses have been within expectations and the provisions established. However, we cannot guarantee that we will continue to experience credit loss rates similar to those experienced in the past.

Our accounts receivable are generally highly concentrated among a small number of customers, and a significant change in the liquidity or financial position of one of these customers could have a material adverse effect on the collectability of our accounts receivable, liquidity and future operating results.





Inventories



We value inventories at the lower of cost or the net realizable value. Cost is determined on an average cost basis which approximates actual cost on a first-in, first-out basis and includes raw materials, labor and manufacturing overhead. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. On a regular basis, we evaluate inventory balances for excess quantities and obsolescence by analyzing estimated demand, inventory on hand, sales levels and other information and reduce inventory balances to net realizable value for excess and obsolete inventory based on this analysis. Once established, lower of cost or net realizable value write-downs are considered permanent adjustments to the cost basis of the excess or obsolete inventories.

Impairment of Long-Lived Assets

We evaluate the recoverability of the carrying value of long-lived assets held and used by us in our operations for impairment on at least an annual basis or whenever events or changes in circumstances indicate that their carrying value may not be recoverable. When such factors and circumstances exist, we compare the projected undiscounted future net cash flows associated with the related asset or group of assets over their estimated useful lives against their respective carrying amount. These projected future cash flows may vary significantly over time as a result of increased competition, changes in technology, fluctuations in demand, consolidation of our customers and reductions in average sale prices. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss is recognized to the extent the carrying value exceeds the estimated fair value of the asset. The fair value of the asset or asset group is based on market value when available, or when unavailable, on discounted expected cash flows.





Warranty Liability


We offer product warranties generally ranging from one to three years, depending on the product and negotiated terms of any purchase agreements with our customers. Such warranties require us to repair or replace defective product returned to us during the warranty period at no cost to the customer. Warranties are not offered on sales of component products. We record an estimate for warranty-related costs at the time of sale based on our historical and estimated future product return rates and expected repair or replacement costs. While such costs have historically been within management's expectations and the provisions established, unexpected changes in failure rates could have a material adverse impact on us, requiring additional warranty reserves, and could adversely affect our gross profit and gross margins.





Stock-Based Compensation


Stock-based awards are comprised principally of stock options, restricted stocks and restricted stock units. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as an expense over the requisite service period, which is the vesting period, on a straight-line basis, net of estimated forfeitures. We use the Black-Scholes option pricing model to determine the grant date fair value of stock options. The model requires us to estimate the expected volatility and expected term of the stock options, which are highly complex and subjective variables. The expected volatility is based on the historical volatility of our common stock. The expected term is computed using the simplified method as our best estimate given our lack of actual exercise history. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected term of the grant effective as of the date of the grant. The expected dividend assumption is based on our history and management's



                                       47

Table of Contents

expectation regarding dividend payouts. The grant-date fair value of restricted stocks and restricted stock units equals the closing price of our common stock on the grant date.

Prior to the adoption of Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07" or "Topic 718") in the second quarter of 2018, we accounted for equity-based awards to non-employees in accordance with ASC Topic 505, Equity. All transactions in which goods or services were the consideration received for the issuance of equity instruments were accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever was more reliably measurable. The measurement date used to determine the estimated fair value of the equity instrument issued was the earlier of the date on which the third-party performance was complete or the date on which it was probable that performance would occur. Upon the adoption of ASU No. 2018-07, we account for all stock-based awards in accordance with Topic 718.





Income Taxes



Deferred income tax assets and liabilities are recognized for temporary differences between the financial statement carrying amounts of assets and liabilities and the amounts that are reported in the income tax returns. Deferred taxes are evaluated for realization on a jurisdictional basis. We record valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. In making this assessment, management analyzes future taxable income, reversing temporary differences and ongoing tax planning strategies. Should a change in circumstances lead to a change in judgment about the realizability of deferred tax assets in future years, we will adjust related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of our position. The tax benefit recognized in the financial statements for a particular tax position is based on the largest benefit that is more likely than not to be realized. The amount of unrecognized tax benefits is adjusted as appropriate for changes in facts and circumstances, such as significant amendments to existing tax laws, new regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. We recognize both accrued interest and penalties associated with uncertain tax positions as a component of provision for income taxes in the consolidated statements of operations.

The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws and regulations may change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations and court rulings. Therefore, the actual liability for U.S. or foreign taxes may be materially different from our estimates, which could require us to record additional tax liabilities or to reduce previously recorded tax liabilities, as applicable.
