No shares of preferred stock were outstanding at September 28, 2019 or December 29, 2018. On April 17, 2017, the Company entered into a rights agreement (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-thousandth of a share (a “Unit”) of Series A Preferred Stock of the Company (the “Preferred Stock”), at a purchase price of $6.56 per Unit, subject to adjustment. Subject to the provisions of the Rights Agreement, including certain exceptions specified therein, a distribution date for the Rights (the “Distribution Date”) will occur upon the earlier of (i) 10 business days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired or otherwise obtained beneficial ownership of 15% or more of the then‑outstanding shares of the Company’s common stock, and (ii) 10 business days (or such later date as may be determined by the Company’s board of directors) following the commencement of a tender offer or exchange offer that would result in a person or group becoming an Acquiring Person. The Rights are not exercisable until the Distribution Date and, unless earlier redeemed or exchanged by the Company pursuant to the terms of the Rights Agreement, will expire on the earlier of (i) the close of business on April 17, 2018, the first anniversary of the adoption of the Rights Agreement, and (ii) the date of any settlement, adjudication, dismissal with prejudice, abandonment by the Company or other conclusive and final resolution of the Company’s legal proceedings against SK hynix (see Note 7). 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. On April 16, 2018, the Company entered into an amendment (the “Amendment”) to the Rights Agreement, which amended the definition of “Expiration Date” in the Rights Agreement to incorporate all of the Company’s legal proceedings against SK hynix, and amended the definition of “Final Expiration Date” in the Rights Agreement to mean the close of business on April 17, 2019. On April 17, 2019, the Company entered into a second amendment (the “Second Amendment”) to the Rights Agreement, which further amended the definition of “Expiration Date” in the Rights Agreement to extend the final expiration for an additional two years to April 17, 2021. As a result, the Rights will expire and become unexercisable on or before the close of business on April 17, 2021. Common Stock Purchase Agreement On June 24, 2019, the Company entered into the Purchase Agreement with Lincoln Park, pursuant to which the Company has the right to sell to Lincoln Park up to an aggregate of $10 million in shares of its common stock subject to the conditions and limitations set forth in the Purchase Agreement. As consideration for entering into the Purchase Agreement, the Company issued to Lincoln Park 818,420 shares of its common stock as initial commitment shares in a noncash transaction on June 24, 2019 and will issue up to 818,420 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. During the three and nine months ended September 28, 2019, Lincoln Park purchased an aggregate of 8,189,364 shares of the Company’s common stock for a net purchase price of $2.5 million. In connection with the purchases, the Company issued to Lincoln Park an aggregate of 204,771 shares of its common stock as additional commitment shares in a noncash transaction. Pursuant to the Purchase Agreement, on any business day and as often as every other business day over the 36-month term of the Purchase Agreement, the Company has the right, from time to time, at its sole discretion and subject to certain conditions, to direct Lincoln Park to purchase up to 400,000 shares of its common stock, with such amount increasing as the closing sale price of its common stock increases; provided Lincoln Park’s obligation under any single such purchase will not exceed $1.0 million, unless the Company and Lincoln Park mutually agree to increase the maximum amount of such single purchase (each, a “Regular Purchase”). If the Company directs Lincoln Park to purchase the maximum number of shares of common stock it then may sell in a Regular Purchase, then in addition to such Regular Purchase, and subject to certain conditions and limitations in the Purchase Agreement, the Company may direct Lincoln Park to purchase an additional amount of common stock that may not exceed the lesser of (i) 300% the number of shares purchased pursuant to the corresponding Regular Purchase or (ii) 30% of the total number of shares of its common stock traded during a specified period on the applicable purchase date as set forth in the Purchase Agreement (“Accelerated Purchase”). Under certain circumstances and in accordance with the Purchase Agreement, the Company may direct Lincoln Park to purchase shares in multiple Accelerated Purchases on the same trading day. Subsequent to September 28, 2019, Lincoln Park purchased an aggregate of 9,655,398 shares of the Company’s common stock for a net purchase price of $3.5 million. In connection with the purchases, the Company issued to Lincoln Park an aggregate of 283,506 shares of its common stock as additional commitment shares in a noncash transaction. 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 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 Purchase Agreement. In all instances, the Company may not sell shares of its common stock to Lincoln Park under the Purchase Agreement if that would result in Lincoln Park beneficially owning more than 9.99% of its common stock. The 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 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 Purchase Agreement. The Company has the right to terminate the Purchase Agreement at any time, at no cost to the Company. Warrants As of September 28, 2019, there were outstanding warrants to purchase an aggregate of 15,010,012 shares of the Company’s common stock with a weighted-average exercise price of $0.62. There were no activities during the nine months ended September 28, 2019.
