Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2—Summary of Significant Accounting Policies ​ Basis of Presentation ​ The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Certain information and footnote disclosures normally included in the condensed consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These condensed consolidated financial statements should be read in conjunction with the condensed consolidated financial statements and notes thereto as of and for the year ended January 1, 2022, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 1, 2022 (the “2021 Annual Report”). ​ In the opinion of management, all adjustments for the fair presentation of the Company’s condensed consolidated financial statements have been made. The adjustments are of a normal recurring nature except as otherwise noted. The results of operations for the interim periods are not necessarily indicative of the results to be expected for other periods or the full fiscal year. The Company has evaluated events occurring subsequent to April 2, 2022 through the filing date of this Quarterly Report on Form 10-Q and concluded that there were no events that required recognition and disclosures other than those discussed elsewhere in the notes hereto. ​ Principles of Consolidation ​ ​ Fiscal Year ​ The Company’s fiscal year is the 52- or 53-week period that ends on the Saturday nearest to December 31. The Company’s fiscal year 2022 will include 52 weeks and ends on December 31, 2022. Each quarter of fiscal year 2022 will be comprised of 13 weeks. Unless otherwise stated, references to particular years, quarters, months and periods refer to the Company’s fiscal years ended in January and the associated quarters, months and periods of those fiscal years. ​ Use of Estimates ​ The preparation of the accompanying condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results may differ materially from those estimates. ​ ​ Recently Issued Accounting Guidance ​ In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . This ASU amends the guidance on convertible instruments and the derivatives scope exception for contracts in an entity's own equity, and also improves and amends the related earnings per share guidance for both Subtopics. The ASU was effective for the three months ended April 2, 2022. The adoption of this ASU did not have an impact on the Company’s condensed consolidated financial statements as the Company paid off its convertible debt in December 2021.

These potential weighted average common share equivalents have been excluded from the diluted net loss per share calculations above as their effect would be anti-dilutive (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ April 2, ​ April 3, ​ 2022 2021 Weighted average common share equivalents $ 6,369 ​ $ 17,082 ​ Disaggregation of Net Sales ​ The following table shows disaggregated net sales by major source (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ April 2, ​ April 3, ​ 2022 2021 Resales of third-party products $ 45,585 $ 11,358 Sale of the Company's modular memory subsystems 4,615 3,539 Total net sales $ 50,200 $ 14,897 ​ Major Customers and Products ​ The Company’s net product sales have historically been concentrated in a small number of customers. The following table sets forth the percentage of net product sales made to customers that each comprise 10% or more of total product sales: ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ ​ April 2, ​ April 3, ​ ​ 2022 2021 ​ Customer A * % 10 % Customer B * % 10 % Customer C ​ 53 % * % ​ * Less than 10% of net sales during the period. ​ As of April 2, 2022, one customer represented 36% of aggregated gross receivables. As of January 1, 2022, four customers represented 26%, 16%, 13%, and 13% of aggregate gross receivables, respectively. The loss of a major customer or a reduction in sales to or difficulties collecting payments from these customers could significantly reduce the Company’s net sales and adversely affect its operating results. The Company mitigates risks associated with foreign and domestic receivables by purchasing comprehensive credit insurance. ​ The Company resells certain 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. For the three months ended April 2, 2022 and April 3, 2021, resales of these products represented approximately 91% and 76% of net product sales, respectively.

Commitments and Contingencies
Commitments and Contingencies	​ Note 7 – Commitments and Contingencies ​ Contingent Legal Expenses ​ whereby such law firms are paid on a scaled percentage of any negotiated fee, settlements or judgments awarded based on how and when the fees, settlements or judgments are obtained. ​ Litigation and Patent Reexaminations ​ We own numerous patents and continue to seek to grow and strengthen our patent portfolio, which covers various aspects of our innovations and includes various claim scopes. We plan to pursue avenues to monetize our intellectual property portfolio, in which we would generate revenue by selling or licensing our technology, and we intend to vigorously enforce our patent rights against alleged infringers of such rights. We 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 the U.S. Patent and Trademark Office (“USPTO”) Patent Trial and Appeal Board (“PTAB”). 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, or that we will be able to monetize our intellectual property portfolio. We are also subject to litigation based on claims that we have infringed on 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 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. ​ Google Litigation ​ On December 4, 2009, Netlist filed a patent infringement lawsuit against Google, Inc. (“Google”) in the U.S. District Court for the Northern District of California (the “NDCA”), seeking damages and injunctive relief based on Google’s alleged infringement of our U.S. Patent No. 7,619,912 (the “‘912 patent”) which relates generally to technologies to implement rank multiplication. The NDCA case was stayed, pending challenges to the ‘912 patent before the United States Patent and Trademark Office. Eventually, the United States Court of Appeals for the Federal Circuit confirmed the ‘912 patent’s validity on June 15, 2020, and the NDCA case stay was lifted. the case proceeded before Senior Judge Armstrong, where the parties entered cross motions for summary judgment. Of the issues in play, the parties contested the application of the defense of intervening rights to the claims at issue in the case. Afterward, the NDCA case was re-assigned to Chief Judge Seeborg of the NDCA, and the hearing for the parties’ cross motions took place on March 3, 2022. On May 5, 2022, Chief Judge Seeborg entered an Order granting Netlist, Inc.’s Motion for Summary Judgement that Claim 16 of the ‘912 patent is not subject to Google’s pleaded defense of Intervening Rights, while also entering orders on other issues, including setting a remote case management conference for June 23, 2022 at 10:00am pacific time. ​ Micron Litigation ​ On April 28, 2021, Netlist filed a complaint for patent infringement against Micron Technology, Inc. (“Micron”) in the United States District Court for the Western District of Texas, Waco Division (Case No. 6:21-cv00431 & Case No. 6:21-cv-00430) These proceedings are based on the alleged infringement by Micron’s load reduced dual in line memory modules (“LRDIMM”) and Micron’s non-volatile dual in line memory modules (“NVDIMM”) enterprise memory modules under four U.S. patents – US Pat. No. 10,489,314; US Pat. No. 9,824,035; US Pat. No. 10,268,608; & US Pat. No. 8,301,833. As of the reporting date, the case has been assigned to Hon. Judge Lee Yeakel, and the parties completed briefing on their claim construction arguments. The matter is set for a Claim Construction hearing on May 12, 2022. ​ In parallel, Micron filed requests to bring Inter Partes Review (“IPR”) proceedings against all four asserted patents: U.S. Patents 8,301,833, 9,854,035, 10,268,608, and 10,489,314. As of the reporting date, the PTAB has not made a decision with respect any of these IPR requests. ​ Samsung Litigations ​ On May 28, 2020, Netlist filed a complaint against Samsung in the United States District Court for the Central District of California for Samsung’s breach of the parties’ JDLA. On July 22, 2020, Netlist amended its complaint to seek a Declaratory Judgment that it properly terminated the JDLA in light of Samsung’s material breaches. On October 14, 2021, the Court entered summary judgment in Netlist’s favor and confirmed Netlist properly terminated the JDLA as of July 15, 2020. On February 15, 2022, the Court entered a Final Judgment in favor of Netlist on each of its three claims and confirmed conclusively that all licenses granted under the JDLA were terminated. On February 25, 2022, Samsung filed a Notice of Appeal, and the Federal Court of Appeals for the Ninth Circuit issued a Time Schedule Order on February 28, 2022, setting Samsung’s deadline to file an opening appeal brief as June 6, 2022. Netlist noticed its intention to file a cross-appeal and the Ninth Circuit confirmed a contemporaneous briefing deadline of June 6, 2022, for the same. ​ On October 15, 2021, Samsung filed a declaratory judgement action against Netlist in the United States District Court for the District of Delaware (“DDE”), requesting in relevant part that the Delaware District Court declare that Samsung does not infringe Netlist’s U.S. Patent Nos. 7,619,912, 9,858,218, 10,217,523, 10,474,595, 10,860,506, 10,949,339, and 11,016,918. As of the reporting date, Samsung seeks leave to add U.S. Pat. 11,232,054 (issued Jan. 25, 2022) to the action. Netlist believes Samsung’s claims levied in the DDE action meritless, and the relief Samsung requests unjustified. As of the reporting date, Netlist filed a motion seeking dismissal of Samsung’s DDE complaint, and an opposition contesting the inclusion of U.S. Pat. 11,232,054 as part of a second amended complaint filing. The matter is fully briefed, and Netlist awaits an order from the Court. ​ On November 19, 2021, Samsung filed IPR proceedings contesting the validity of U.S. Patents 9,858,218 (the “’218 patent”), 10,474,595 (the “’595 patent”), and 10,217,523 (the “’523 patent”). Netlist filed its initial responses to Samsung’s petitions on February 18, 2022, contesting the institution of any IPR on the grounds propounded. As of the reporting date, the PTAB has not yet made decision with respect to the IPR requests related to the ‘218 or ‘595 patents, but did enter an order instituting IPR proceedings for the ‘523 patent on May 5, 2022. On February 17, 2022, Samsung filed a separate IPR request contesting the validity of only claim 16 within Netlist’s U.S. Patent 7,619,912. The PTAB issued a filing date for this challenge of the ‘912 patent, making Netlist’s Patent Owner Preliminary Response due on July 21, 2022. As of the reporting date, Samsung has filed two additional IPR proceedings contesting the validity of Netlist’s U.S. Patents 10,860,506 and 10,949,339. The PTAB issued filing dates for both, making Netlist’s deadline to file its Preliminary Responses to each on July 21, 2022 and July 28, 2022, respectively, ​ On December 20, 2021, Netlist filed for a complaint for patent infringement against Samsung in the United States Court for the Eastern District of Texas (Case No. 2:21-cv-463) under US Pat. No. 10,860,506; US Pat. No. 10,949,339; & US Pat. No. 11,016,918. Samsung responded to Netlist’s complaint on April 12, 2022, and Judge Gilstrap ordered a scheduling conference be set for May 18, 2022. On May 3, 2022, Netlist entered a First Amended Complaint pursuant to FRCP Rule 15, adding claims for infringement under three additional patents: U.S. Patents 8,787,060, 9,318,160, and 11,232,054. On May 4, 2022, Netlist complied with the EDTX local patent rules and served its preliminary infringement contentions on Samsung. As of the reporting date, Netlist awaits its opportunity to appear in Judge Gilstrap’s ordered case management conference. ​ Other Contingent Obligations ​ In the ordinary course of our business, we have made certain indemnities, commitments and guarantees pursuant to which we may be required to make payments in relation to certain transactions. These include, among others: (i) intellectual property indemnities to our customers and licensees in connection with the use, sale and/or license of our products; (ii) indemnities to vendors and service providers pertaining to claims based on our negligence or willful misconduct; (iii) indemnities involving the accuracy of representations and warranties in certain contracts; (iv) indemnities to our directors and officers to the maximum extent permitted under the laws of the State of Delaware; (v) indemnities to SVB pertaining to all obligations, demands, claims, and liabilities claimed or asserted by any other party in connection with transactions contemplated by the applicable investment or loan documents, as applicable; and (vi) indemnities or other claims related to certain real estate leases, under which we may be required to indemnify property owners for environmental and other liabilities or may face other claims arising from our use of the applicable premises. The duration of these indemnities, commitments and guarantees varies and, in certain cases, may be indefinite. The majority of these indemnities, commitments and guarantees do not provide for any limitation of the maximum potential for future payments we could be obligated to make. Historically, we have not been obligated to make significant payments as a result of these obligations, and no liabilities have been recorded for these indemnities, commitments and guarantees in the accompanying consolidated balance sheets. ​

No shares of preferred stock were outstanding as of April 2, 2022 or January 2, 2022. ​ On April 17, 2017, the Company entered into a rights agreement (as amended from time to time, the “Rights Agreement”) with Computershare Trust Company, N.A., as rights agent. In connection with the adoption of the Rights Agreement and pursuant to its terms, the Company’s board of directors authorized and declared a dividend of one right (each, a “Right”) for each outstanding share of the Company’s common stock to stockholders of record at the close of business on May 18, 2017 (the “Record Date”), and authorized the issuance of one Right for each share of the Company’s common stock issued by the Company (except as otherwise provided in the Rights Agreement) between the Record Date and the Distribution Date (as defined below). ​ Each Right entitles the registered holder, subject to the terms of the Rights Agreement, to purchase from the Company, when exercisable and subject to adjustment, one unit consisting of one one 10 ​ In connection with the adoption of the Rights Agreement, the Company’s board of directors approved a Certificate of Designation of the Series A Preferred Stock (the “Certificate of Designation”) designating 1,000,000 shares of its serial preferred stock as Series A Preferred Stock and setting forth the rights, preferences and limitations of the Preferred Stock. The Company filed the Certificate of Designation with the Secretary of State of the State of Delaware on April 17, 2017. ​ Common Stock ​ September 2021 Lincoln Park Purchase Agreement ​ On September 28, 2021, the Company entered into a purchase agreement (the “September 2021 Purchase Agreement”) with Lincoln Park, pursuant to which the Company has the right to sell to Lincoln Park up to an aggregate of $75 million in shares of its common stock subject to the conditions and limitations set forth in the September 2021 Purchase Agreement. Concurrent with the execution of the September 2021 Purchase Agreement, the Company also entered into a registration rights agreement with Lincoln Park relating to the Company’s common stock to be sold to Lincoln Park. As consideration for entering into the September 2021 Purchase Agreement, the Company issued to Lincoln Park 218,750 shares of its common stock as initial commitment shares in a noncash transaction on September 28, 2021 and will issue up to 143,750 additional shares of its common stock as additional commitment shares on a pro rata basis in connection with any additional purchases. The Company will not receive any cash proceeds from the issuance of these additional commitment shares. ​ Pursuant to the September 2021 Purchase Agreement, on any business day and as often as every other business day over the 36-month ​ The Company controls the timing and amount of any sales of its common stock to Lincoln Park. There is no upper limit on the price per share that Lincoln Park must pay for the Company’s common stock under the September 2021 Purchase Agreement, but in no event will shares be sold to Lincoln Park on a day the closing price is less than the floor price specified in the September 2021 Purchase Agreement. In all instances, the Company may not sell shares of its common stock to Lincoln Park under the September 2021 Purchase Agreement if that would result in Lincoln Park beneficially owning more than 9.99% of its common stock. ​ The September 2021 Purchase Agreement does not limit the Company’s ability to raise capital from other sources at the Company’s sole discretion, except that, subject to certain exceptions, the Company may not enter into any Variable Rate Transaction (as defined in the September 2021 Purchase Agreement, including the issuance of any floating conversion rate or variable priced equity-like securities) during the 36 months after the date of the September 2021 Purchase Agreement. The Company has the right to terminate the September 2021 Purchase Agreement at any time, at no cost to the Company. ​ During 2021, Lincoln Park purchased an aggregate of 1,550,000 shares of our common stock for a net purchase price of $10.9 million under the September 2021 Purchase Agreement. In connection with the purchases, we issued to Lincoln Park an aggregate of 20,809 shares of our common stock as additional commitment shares in noncash transactions. During the first quarter of 2022, Lincoln Park purchased an aggregate of 300,000 shares of our common stock for a net purchase price of $1.8 million under the September 2021 Purchase Agreement.
