| Stockholders' Equity | Stockholders’ Equity Reverse Stock Split On May 9, 2022, the stockholders of the Company authorized the Board of Directors to effect a reverse stock split of all outstanding shares of common stock. The Board of Directors subsequently approved the implementation of a reverse stock split as a ratio of one-for-eleven shares, which became effective on May 13, 2022. The Company’s outstanding stock options were also adjusted to reflect the one-for-eleven reverse stock split of the Company’s common stock. Outstanding stock options were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased. Preferred Stock On April 6, 2022, the Company and DaVita entered into the SPA, which provided for the issuance by the Company of up to $15 million of preferred stock to DaVita. On April 6, 2022, the Company issued 7,500 shares of Series X Preferred Stock for gross proceeds of $7.5 million. On June 2, 2022, the Company met the conditions for the Second Tranche through a Registered Direct and Private Placement Offering by raising $15 million in additional capital. As a result, on June 16, 2022 the Company issued an additional 7,500 shares of the Series X Preferred Stock to DaVita for gross proceeds of $7.5 million. The Series X Preferred Stock was issued for a price of $1,000 per share (the "Face Amount"), subject to accretion at a rate of 1% per annum, compounded annually. If the Company’s common stock trades above $22.00 for a period of 30 calendar days, the accretion will thereafter cease. The Series X Convertible Preferred Stock is convertible to common stock at rate equal to the Face Amount, divided by a conversion price of $11.00 per share (subject to adjustment for future stock splits, reverse stock splits and similar recapitalization events). As a result, each share of Series X Preferred Stock will initially convert into approximately 91 shares of common stock. DaVita’s right to convert to common stock is subject to a beneficial ownership limitation, which is initially set at 9.9% of the outstanding common stock, which limitation may be reset (not to exceed 19.9%) at DaVita’s option and upon providing prior written notice to the Company. In addition, any debt financing is limited by the terms of our Securities Purchase Agreement with DaVita. Specifically, until DaVita owns less than 50% of its investment, the Company may only incur additional debt in the form of a purchase money loan, a working capital line of up to $5 million or to refinance existing debt, unless DaVita consents. Additionally, the Series X Preferred Stock has a deemed liquidation event and redemption clause which could be triggered if the sale of all or substantially all of the Company's assets relating to the Company's dialysis concentrates business line. Since the Series X Preferred Stock may be redeemed if certain assets are sold at the option of the holder, but is not mandatorily redeemable, the preferred stock has been classified as permanent equity and initially recognized at fair value of $15 million (the proceeds on the date of issuance) less issuance costs of $0.1 million, resulting in an initial value of $14.9 million. The Company will assess at each reporting period whether conditions have changed to now meet the mandatorily redemptive definition which could trigger liability classification. As of September 30, 2022 and December 31, 2021, there were 2,000,000 shares of preferred stock, $0.0001 par value per share, authorized and 15,000 and nil shares of preferred stock issued and outstanding, respectively. Common Stock As of September 30, 2022 and December 31, 2021, there were 170,000,000 shares of common stock, $0.0001 par value per share, authorized and 11,152,673 and 8,544,225 shares issued and outstanding, respectively. Controlled Equity Offering On April 8, 2022, the Company entered into the Sales Agreement with Cantor Fitzgerald & Co. as Agent, pursuant to which the Company may offer and sell from time to time up to $12,200,000 of shares of Company’s common stock through the Agent. The offering and sale of such shares has been registered under the Securities Act of 1933, as amended, pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-259923) (the “Registration Statement”), which was originally filed with the SEC on September 30, 2021 and declared effective by the SEC on October 8, 2021, the base prospectus contained within the Registration Statement, and a prospectus supplement that was filed with the SEC on April 8, 2022. In May 2022, the Company sold 7,500 shares of its common stock pursuant to the Sales Agreement for gross proceeds of $15,135, at a weighted average selling price of approximately $2.02. The Company paid $378 in commissions and offering fees related to the sale of shares of common stock. Under the RD Purchase Agreement and the PIPE Purchase Agreement discussed below, the Company has agreed not to make any sales under any at-the-market offering facility, including pursuant to the Sales Agreement, until at least January 1, 2023 (or until such later time when the Company is permitted to make additional sales under Instruction I.B.6 to Form S-3). Registered Direct Offering On May 30, 2022, the Company entered into the RD Purchase Agreement with the Purchaser named therein, pursuant to which the Company agreed to issue and sell, in a registered direct offering (the “Offering”), 844,613 shares of its common stock at price of $1.39 per share, and pre-funded warrants to purchase up to an aggregate of 7,788,480 shares of common stock (the “Pre-Funded Warrants” and the shares of common stock underlying the Pre-Funded Warrants, the “Warrant Shares”). The purchase price of each Pre-Funded Warrant is equal to the price at which a share of common stock was sold to the public in the Offering, minus $0.0001, and the exercise price of each Pre-Funded Warrant is $0.0001 per share. A holder (together with its affiliates) may not exercise any portion of the Pre-Funded Warrants to the extent the holder would own more than 9.99% of the Company’s outstanding common stock immediately after exercise, as such percentage ownership is determined in accordance with the terms of the Pre-Funded Warrant. The RD Purchase Agreement contains customary representations and warranties and agreements of the Company and the Purchaser and customary indemnification rights and obligations of the parties. A total of 7,311,000 Pre-Funded Warrants remained outstanding as of September 30, 2022. Private Placement Also on May 30, 2022, concurrently with the Offering, the Company entered into the PIPE Purchase Agreement relating to the offering and sale (the “Private Placement”) of warrants to purchase up to a total of 9,900,990 shares of common stock and pre-funded warrants to purchase up to a total of 1,267,897 shares of common stock (the “PIPE Warrants”). Each warrant was sold at a price of $0.125 per underlying warrant share and is exercisable at an exercise price of $1.39 per share. The purchase price of each Pre-Funded Warrant was equal to the price at which a share of common stock was sold to the public in the Offering, minus $0.0001, and the exercise price of each prefunded warrant is $0.0001 per share. As of September 30, 2022 9,900,990 PIPE Warrants and no Pre-Funded PIPE Warrants remained outstanding. In connection with the Private Placement, the Company entered into a Registration Rights Agreement with the Purchaser, dated as of June 2, 2022 (the “RRA”). Pursuant to the RRA, the Company was required to prepare and file a registration statement with the SEC no later than July 1, 2022, and to use its reasonable best efforts to have the registration statement declared effective as promptly as possible, subject to certain specified penalties if timely effectiveness is not achieved. The Company filed a registration statement on June 22, 2022 which became effective on July 5, 2022. The Offering and the Private Placement closed on June 2, 2022. The net proceeds to the Company from the Offering and the Private Placement were approximately $14.9 million, after deducting fees and expenses. Subject to certain ownership limitations, the PIPE Warrants are exercisable upon issuance. The Company has accounted for the common stock related to the Offering and Private Placement as equity on the accompanying consolidated balance sheets as of September 30, 2022. The amount allocated to common stock was $2.0 million. This allocation is equal to the total proceeds of $15.0 million less the amount allocated to Warrants of $12.9 million and is also net of the direct and incremental costs associated with the Offering and Private Placement of $0.1 million. The Black-Scholes pricing model was used to calculate the value of Warrants relating to the Offering and Private Placement. |
