Equity July-December 2018 Preferred Stock Conversion From July through December of 2018, Series B Convertible Preferred shareholders of the Company converted 10,926 shares of Series B Convertible Preferred Stock into 17,098,973 shares of common stock. August 2018 Warrant Exercise During August 2018, pursuant to the cashless exercise provision contained in their warrant, L2 Capital exercised its warrants and was issued 242,063 shares of common stock. The L2 Capital warrant is no longer outstanding. July 2018 Warrant Exercise During May 2018, the Company closed on a public offering, consisting of both convertible preferred stock and warrants. During July 2018, 29,927 of the warrants were exercised and converted into 29,927 shares of common stock. May-June 2018 Preferred Stock Conversion During both May 2018 and June 2018, Series B Convertible Preferred shareholders of the Company converted 4,072 shares of Series B Convertible Preferred Stock into 3,086,570 shares of common stock. May 2018 Warrant Exercise (July 2016 Warrants) During March 2018, the Company repriced 832,000 warrants dated July 8, 2016, from $12 to $2.125 (for further description see Warrant Reprice March 2018 below). During May 2018, an additional 145,834 of the repriced warrants were exercised resulting in gross proceeds to the Company of $0.3 million. May 2018 Unit Offering On May 14, 2018, the Company closed on an underwritten public offering of units (“the Units”), consisting of convertible preferred stock and warrants, for gross proceeds of $15.0 million, which excludes underwriting discounts and commissions and offering expenses payable by SINTX. The offering was priced at a public offering price of $1,000 per unit. Each unit consisted of one share of Series B Convertible Preferred Stock, with a stated value of $1,100, and warrants to purchase up to 758 shares of common stock (the “May 2018 Warrants”). The May 2018 Warrants are initially exercisable at an exercise price of $1.60 per share and expire 5 years from the date of issuance. The Series B Preferred Stock is convertible into shares of common stock by dividing the stated value of $1,100 by: (i) for the first 40 trading days following the closing of this offering, $1.4512 (the “Conversion Price”), (ii) after 40 trading days but prior to the 81st trading day, the lesser of  (a) the Conversion Price and (b) 87.5% of the lowest volume weighted average price for our Common Stock as reported at the close of trading on the market reporting trade prices for the Common Stock during the five trading days prior to the 41st trading day, and (iii) after 80 trading days, the lesser of  (a) the Conversion Price and (b) 87.5% of the lowest volume weighted average price for our Common Stock as reported at the close of trading on the market reporting trade prices for the Common Stock during the five trading days prior to the date of the notice of conversion. In the case of (ii)(b) and (iii)(b) above, the share price shall not be less than $0.48 (the “Floor Price”). Each of the Conversion Price and Floor Price is subject to adjustment in certain circumstances. The Company raised $15.0 million associated with the issuance of the Units, with $6.8 million, net of issuance costs of $0.6 million, allocated to the preferred stock and $6.9 million, net of issuance costs of $0.7 million, allocated to the warrants. In association with the warrants that were recorded as a derivative liability, the Company immediately expensed approximately $0.7 million of issuance costs. The 15,000 preferred shares were initially convertible into 11,369,900 shares of common stock and had an effective conversion rate of $1.45 per share based on the proceeds that were allocated to them. The conversion price was adjusted to $0.6543, effective July 12, 2018, and was adjusted again on September 7, 2018 to $0.48. Warrant Reprice March 2018 During the three months ended March 31, 2018, the Company entered into a warrant amendment agreement (the “Amendment Agreement”) with certain holders of previously issued Series E Common Stock Purchase Warrants (collectively, “Investors”). In connection with that certain Series E Common Stock Purchase Warrant between the Company and Investors dated July 8, 2016, the Company issued to Investors warrants to purchase up to 832,000 shares of common stock (the “Warrant Shares”) at an exercise price of $12.00 per share, (the “Investors Warrants”). Under the terms of the Amendment Agreement, in consideration of Investors exercising 668,335 of the Investors Warrants (the “Warrant Exercise”), the exercise price per share of the Investors Warrants was reduced to $2.125 per share. 668,335 of the Investors Warrants were exercised resulting in gross proceeds to the Company of $1.4 million before payment of placement agent fees and costs. In addition, and as further consideration, the Company issued to Investors new warrants to purchase up to the number of shares of common stock equal to 100% of the number of Warrant Shares issued pursuant to the Warrant Exercise at an exercise price per share equal to $2.00 per share. January 2017 Offering During 2017, the Company completed a secondary offering in which the Company sold 741,667 shares of common stock and warrants to purchase 333,750 shares of common stock. The Company received approximately $3.9 million in proceeds from the offering, with $3.1 million, net of issuance costs of $0.6 million, allocated to common stock and $0.8 million allocated to the warrants. In association with the warrants that were recorded as a derivative liability, the Company immediately expensed $0.1 million of issuance costs. The warrants became exercisable on the closing date, expire on the five-year anniversary of the closing date, and have an initial exercise price per share equal to $6.60 subject to adjustments for events of recapitalization, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting the Company’s common stock. On February 24, 2017, the underwriter in the 2017 secondary offering exercised its option to purchase additional warrants for 30,000 shares of the Company’s common stock. July 2016 Offering In July 2016, the Company completed a secondary offering in which the Company sold 5,258,000 Class A Units, including 1,650,000 units sold pursuant to the exercise by the underwriters of their over-allotment option, priced at $1.00 per unit, and 7,392 Class B Units, priced at $1,000 per unit. Each Class A Unit consisted of 1/12th share of common stock and one warrant to purchase 1/12th share of common stock. Each Class B Unit consisted of one share of preferred stock convertible into 83 shares of common stock and warrants to purchase 83 shares of common stock. The securities comprising the units were immediately separable and were issued separately. In total, the Company issued 438,167 shares of common stock, 7,392 shares of preferred stock convertible into 616,000 shares of common stock and warrants to purchase 1,054,167 shares of common stock at a fixed exercise price of $12.00 per share. The Company received proceeds of approximately $11.4 million, net of underwriting and other offering costs. The Company raised $4.9 million associated with the Class A Units, with $2.5 million, net of issuance costs of $0.3 million, allocated to the common stock and $2.4 million allocated to the warrants. The Company also raised $7.0 million associated with the Class B Units with $3.6 million, net of issuance costs of $0.4 million, allocated to preferred stock and $3.4 million allocated to the warrants. The $5.8 million allocated to warrants were recorded as a derivative liability. In association with the warrants that were recorded as a derivative liability, the Company immediately expensed approximately $0.5 million of issuance costs. The 7,392 preferred shares were convertible into 616,000 shares of common stock and had an effective conversion rate of $6.48 per share based on the proceeds that were allocated to them. The stock price on July 8, 2016, was $10.56 per share which resulted in a fair value in excess of carrying value of $4.08 per share or $2.5 million in total. The fair value in excess of carrying value, or beneficial conversion feature, was recorded as an adjustment within equity (e.g., deemed dividend). The Company recorded a non-cash, deemed dividend of $6.3 million ($2.5 and $3.8 million—calculated as $0.4 million in offering costs plus $3.4 million measured as the difference between the stated value and the allocated proceeds) related to a beneficial conversion feature and accretion of a discount on convertible preferred stock. Subsequent to the secondary offering, all 7,392 shares of convertible preferred stock have been converted into 616,000 shares of common stock. Furthermore, the Company received $0.4 million and issued 37,208 shares of common stock upon the exercise of certain warrants issued in the secondary offering.
