Liquidity and Going Concern Considerations Liquidity and Going Concern Considerations
Since inception, Rockwell has incurred significant net losses and has funded its operations primarily through revenue from commercial products, proceeds from the issuance of debt and equity securities and payments from partnerships. At December 31, 2022, Rockwell had an accumulated deficit of approximately $388.8 million and stockholders' equity of $14.1 million. As of December 31, 2022, Rockwell had approximately $21.5 million of cash, cash equivalents and investments available-for-sale, and working capital of $17.6 million. Net cash used in operating activities for the year ended December 31, 2022 was approximately $17.4 million. These factors raised substantial doubt about the Company’s ability to continue as a going concern and depended, in part, on the degree of success in addressing inflationary pressures affecting the Company’s concentrates business, as well as the Company’s ability to contain costs, raise additional working capital, if needed, and remain in compliance with financial and reporting covenants under the Company’s secured loan.
On April 6, 2022, the Company and DaVita, Inc. ("DaVita") entered into an amendment (the "Amendment") to the Products Purchase Agreement, dated July 1, 2019, under which the Company supplies DaVita with certain dialysis concentrates. Under the Amendment, the Company and DaVita agreed to certain price increases, effective May 1, 2022, as well as the pass-through of certain inflationary costs, determined on a quarterly basis. Certain costs are subject to a cap. The Amendment also requires the Company to implement certain cost containment and cost-cutting measures. The Amendment contains certain covenants with respect to the Company’s ongoing operations, including a minimum cash covenant of $10 million, or the Company will be in default under the Products Purchase Agreement. An event of default could result in termination of that agreement.
On April 6, 2022, the Company and DaVita entered into a Securities Purchase Agreement (the “SPA”), pursuant to which the Company issued $15 million of preferred stock to DaVita in two separate tranches. The Company initially issued 7,500 shares of a newly designated series of preferred stock, which is designated “Series X Convertible Preferred Stock” (the “Series X Preferred Stock”) for gross proceeds of $7,500,000. On June 15, 2022, the Company issued to DaVita an additional 7,500 shares of Series X Preferred Stock in a second closing (the “Second Tranche”) for an additional $7,500,000. The Second
Tranche was conditioned upon the Company raising an additional $15,000,000 in capital within a certain timeline, which took place on June 2, 2022.
On April 8, 2022, the Company entered into a sales agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co. (the “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. During the year ended December 31, 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. Approximately $12.2 million remains available for sale under the ATM facility.
On May 30, 2022, the Company entered into a Securities Purchase Agreement (the “RD Purchase Agreement”) with the purchaser named therein (the “Purchaser”), 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 prefunded 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 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 Pre-Funded Warrant is $0.0001 per share.
Also on May 30, 2022, concurrently with the Offering, the Company entered into a Securities Purchase Agreement with the Purchaser (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. 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.
On November 10, 2022, the Company entered into a Second Amendment to the Loan and Security Agreement (the “Second Amendment”) dated as of November 14, 2022 with Innovatus, which amended the Loan Agreement. Pursuant to the Second Amendment, the Company (i) prepaid an aggregate principal amount of $5.0 million in Term Loans (as defined in the Loan Agreement) in one installment on November 14, 2022; (ii) shall pay interest only payments until September 2023 at which time will resume scheduled debt payments (See Note 16 for more information on our debt facility).
Management evaluated it's going concern by reviewing the Company's operational plans which include executing on the projected financial information including price increases, acquisition of new customers, projected growth of margins and cost containment activities. Additionally, the Company's operational plans also include raising capital, if needed, by using our ATM facility or other methods or forms of financings, subject to existing limitations. Based on the currently available working capital, expectation of the ability of management to execute on the Company's operational plans noted above, management believes the Company currently has sufficient funds to meet its operating requirements for at least the next twelve months from the date of the filing of this report. Accordingly, management believes that the factors noted above which raised substantial doubt about the Company’s ability to continue as a going concern have been alleviated.
The Company may require additional capital to sustain its operations and make the investments it needs to execute its strategic plan. If the Company attempts to obtain additional debt or equity financing, the Company cannot assume such financing will be available on favorable terms, if at all.
Currently, because the Company's public float is less than $75 million, it is subject to the baby shelf limitations under Form S-3, which limits the amount the Company may offer pursuant to its registration statement on Form S-3.

In addition, the Company is subject to certain covenants and cure provisions under its Loan Agreement with Innovatus. As of December 31, 2022, the Company is in compliance with all financial covenants (See Note 16 for further detail).
Global Economic Conditions
The COVID-19 pandemic and resulting domestic and global disruptions, particularly in the supply chain and labor market, among other areas, have adversely affected the Company's business and operations, including, but not limited to, its sales and marketing efforts and its research and development activities, its plant and transportation operations and the operations of third parties upon whom the Company relies. The Company's international business development activities may also continue to be negatively impacted by COVID-19.

In addition, the global macroeconomic environment is uncertain, and could be negatively affected by, among other things, increased U.S. trade tariffs and trade disputes with other countries, instability in the global capital and credit markets, supply chain weaknesses, and instability in the geopolitical environment, including as a result of the Russian invasion of Ukraine and other political tensions, and lingering effects of the COVID-19 pandemic. Such challenges have caused, and may continue to cause, recession fears, rising interest rates, foreign exchange volatility and inflationary pressures. At this time, the Company is unable to quantify the potential effects of this economic instability on our future operations.
Rockwell has utilized a range of financing methods to fund its operations in the past; however, current conditions in the financial and credit markets may limit the availability of funding, refinancing or increase the cost of funding. Due to the rapidly evolving nature of the global situation, it is not possible to predict the extent to which these conditions could adversely affect the Company's liquidity and capital resources in the future.
