ROCKWELL MEDICAL INC

1. Description of Business

Rockwell Medical, Inc. (the "Company", "Rockwell", "we", or "us") is a healthcare company that develops, manufactures, commercializes, and distributes a portfolio of hemodialysis products for dialysis providers worldwide.

Rockwell is the largest supplier of liquid bicarbonate concentrates and the second largest supplier of acid and dry bicarbonate concentrates for dialysis patients in the United States. Hemodialysis is the most common form of end-stage kidney disease treatment and is usually performed at freestanding outpatient dialysis centers, at hospital-based outpatient centers, at skilled nursing facilities, or in a patient’s home.

Rockwell manufactures hemodialysis concentrates at its facilities in Michigan, South Carolina, and Texas totaling approximately 175,000 square feet, and manufactures its dry acid concentrate mixers at its facility in Iowa. Additionally, in July 2023, the Company purchased customer relationships, equipment and inventory from Evoqua Water Technologies related to manufacturing and sale of hemodialysis concentrates products, all of which are manufactured under a contract manufacturing agreement with a third-party organization in Minnesota.

Rockwell delivers the majority of its hemodialysis concentrates products and mixers to dialysis clinics throughout the United States and internationally utilizing its own delivery trucks and third-party carriers.

The Company operates in a single segment.

Rockwell was incorporated in the state of Michigan in 1996 and re-domiciled to the state of Delaware in 2019. Rockwell's headquarters is located at 30142 Wixom Road, Wixom, Michigan 48393.

2. Liquidity and Capital Resources

As of March 31, 2024, Rockwell had approximately $8.6 million of cash, cash equivalents, and investments available-for-sale, and working capital of $11.7 million. Net cash used in operating activities for the three months ended March 31, 2024 was approximately $2.4 million. Based on the currently available working capital along with the expectation of management of its ability to execute on its operational plans as discussed below, 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.

The Company continues to review its operational plans and execute on the acquisition of new customers, and has implemented cost containment activities. The Company may require additional capital to sustain its operations and make the investments it needs to execute its strategic plan. Additionally, the Company's operational plans include raising capital, if needed, by using the remaining $10.4 million available under its at-the-market ("ATM") facility or other methods or forms of financings, subject to existing limitations. 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.

The Company is subject to certain covenants and cure provisions under its Loan Agreement with Innovatus, which, on January 2, 2024, was amended to include, among other things, an interest-only period for 30 months, or up to 36 months if certain conditions are met, and to extend the maturity date to January 1, 2029 (See Note 15 for further detail). As of March 31, 2024, the Company is in compliance with all covenants.

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, recent bank failures in the United States, supply chain weaknesses, and instability in the geopolitical environment, including as a result of the Russian invasion of Ukraine, the Israel-Hamas conflict and other political tensions, and the occurrence of natural disasters and public health crises. 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.

3. Basis of Presentation, Summary of Significant Accounting Policies and Recent Accounting Pronouncements

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the U. S. Securities and Exchange Commission (“SEC”) and on the same basis as the Company prepares its annual audited consolidated financial statements.

The condensed consolidated balance sheet at March 31, 2024, and the condensed consolidated statements of operations, comprehensive loss, and changes in stockholders' equity, and cash flows for the three months ended March 31, 2024 and 2023 are unaudited, but include all adjustments, consisting of normal recurring adjustments the Company considers necessary for a fair presentation of the financial position, operating results, and cash flows for the periods presented. The results for the three months ended March 31, 2024 are not necessarily indicative of results to be expected for the year ending December 31, 2024 or for any future interim period. The condensed consolidated balance sheet at December 31, 2023 has been derived from audited financial statements; however, it does not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2023 and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 as filed with the SEC on March 21, 2024. The Company’s consolidated subsidiaries consist of its wholly-owned subsidiaries, Rockwell Transportation, Inc. and Rockwell Medical India Private Limited.

The accompanying condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Loss Per Share

Basic and diluted net loss per share for the three months ended March 31, 2024 and 2023 was calculated as follows:

Included within the weighted average shares of common stock outstanding for the three months ended March 31, 2023 are 5,911,000 shares of common stock issuable upon the exercise of certain pre-funded warrants, as the warrants were exercisable at any time for nominal consideration and, as such, the shares were considered outstanding for the purpose of calculating basic and diluted net loss per share attributable to common stockholders. There were no unexercised pre-funded warrants as of March 31, 2024.

The Company’s potentially dilutive securities include stock options, restricted stock awards and units, convertible preferred stock and warrants. These securities were excluded from the computations of diluted net loss per share for the three months ended March 31, 2024 and 2023, as the effect would be to reduce the net loss per share. The following table includes the potential shares of common stock, presented based on amounts outstanding at each period end, that were excluded from the

computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:

Adoption of Recent Accounting Pronouncements

The Company continually assesses new accounting pronouncements to determine their applicability. When it is determined a new accounting pronouncement affects the Company’s financial reporting, the Company undertakes a review to determine the consequences of the change to its consolidated financial statements and assures there are sufficient controls in place to ascertain the Company’s consolidated financial statements properly reflect the change.

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting - Improvements to Reportable Segment Disclosures, which updates reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses and information used to assess segment performance. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is in the process of determining the effect this ASU will have on the consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which updates income tax disclosures primarily related to the rate reconciliation and income taxes paid information. This ASU also includes certain other amendments to improve the effectiveness of income tax disclosures. The amendments in this ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is in the process of determining the effect this ASU will have on the consolidated financial statements.

4. Asset Acquisition

On July 10, 2023, the Company executed and consummated the transactions contemplated by an Asset Purchase Agreement (the “Purchase Agreement”) with Evoqua Water Technologies LLC ("Evoqua") (the "Evoqua Acquisition"). Subject to the terms and conditions of the Purchase Agreement, at the closing of the transaction (the “Closing”), the Company purchased customer relationships, equipment and inventory from Evoqua, which were related to its manufacturing and selling of hemodialysis concentrates products, all of which are manufactured under a contract manufacturing agreement with a third-party organization.

Pursuant to the Purchase Agreement, total consideration was $17.4 million, comprising a cash payment at Closing of $12.4 million (inclusive of transaction costs) andtwo $2.5 million deferred payments, the first to be paid on theone-year anniversary of the Closing, which is included as a current liability on the Company's condensed consolidated balance sheet, and the second to be paid on the second anniversary of the Closing (collectively, the “deferred consideration”).

The transaction was accounted for as an asset acquisition, as the acquired assets did not meet the definition of a business as defined by Accounting Standards Codification ("ASC") 805, Business Combinations.

The purchase price was allocated, on a relative fair value basis, to the assets acquired at the July 10, 2023 acquisition date as follows (table in thousands):

The fair value of the customer relationships intangible asset was determined using a multi-period excess earnings method, a form of the income approach, which incorporates the estimated future cash flows to be generated from the customer base. Key assumptions included discounted cash flow, estimated life cycle and customer attrition rates. Customer relationships are being amortized over a period of 20 years. Given that the acquired equipment had been recently purchased and recorded at fair value, the Company determined the fair value of the equipment using a cost approach, which considered assumptions over the equipment's current replacement cost and useful life. Inventory was purchased directly from the contract manufacturer holding the inventory, which approximated fair value.

During the three months ended March 31, 2024, the Company recorded amortization of its customer relationship intangible asset of $0.1 million, resulting in a net intangible asset of $10.6 million as of March 31, 2024.

Estimated future amortization expense on the Company's customer relationships intangible asset as of March 31, 2024 is as follows (table in thousands):

5. Revenue Recognition

The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers, issued by the FASB. The core principle of the revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:

•Step 1: Identify the contract with the customer

•Step 2: Identify the performance obligations in the contract

•Step 3: Determine the transaction price

•Step 4: Allocate the transaction price to the performance obligations in the contract

•Step 5: Recognize revenue when the company satisfies a performance obligation

Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by Rockwell from a customer, are excluded from revenue.

Shipping and handling costs associated with outbound freight related to contracts with customers are accounted for as a fulfillment cost and are included in cost of sales when control of the goods transfers to the customer.

Nature of goods and services

Rockwell operates inone market segment, the hemodialysis market, which involves the manufacture, sale and distribution of hemodialysis products to hemodialysis clinics, including pharmaceutical, dialysis concentrates, dialysis kits and other ancillary products used in the dialysis process.

Rockwell's customer mix is diverse, with most customer sales concentrations under 10% and one customer, DaVita, Inc. ("DaVita"), at approximately 44% and 48% of total net product sales for the three months ended March 31, 2024 and 2023, respectively. Rockwell's accounts receivable from this customer were approximately 19% of the total net consolidated accounts receivable balance at each of March 31, 2024 and December 31, 2023. See below and Note 10 for additional information regarding the Company's contracts with DaVita.

Product Sales

The Company accounts for individual products and services separately if they are distinct (i.e., if a product or service is separately identifiable from other items and if a customer can benefit from it on its own or with other resources that are readily available to the customer). The consideration, including any discounts, is allocated between separate products and services based on their stand-alone selling prices. The stand-alone selling prices are determined based on the cost plus margin approach.

Drug and dialysis concentrate products are sold directly to dialysis clinics and to wholesale distributors in both domestic and international markets. Distribution and license agreements for which upfront fees are received are evaluated upon execution or modification of the agreement to determine if the agreement creates a separate performance obligation from the underlying product sales. For all existing distribution and license agreements, the distribution and license agreement is not a distinct performance obligation from the product sales. In instances where regulatory approval of the product has not been established and the Company does not have sufficient experience with the foreign regulatory body to conclude that regulatory approval is probable, the revenue for the performance obligation is recognized over the term of the license agreement (over time recognition). Conversely, when regulatory approval already exists or is probable, revenue is recognized at the point in time that control of the product transfers to the customer.

For the majority of the Company's international customers, the Company recognizes revenue at the shipping point, which is generally the Company's plant or warehouse. For other business, the Company recognizes revenue based on when the customer takes control of the product. The amount of revenue recognized is based on the purchase order less returns and adjusted for any rebates, discounts, chargebacks or other amounts paid to customers estimated at the time of sale. Customers typically pay for the product based on customary business practices with payment terms averaging 30 days, while a small subset of customers have payment terms averaging 60 days.

Deferred License Revenue

The Company received upfront fees under five distribution and license agreements that have been deferred as a contract liability and presented on the accompanying condensed consolidated balance sheets as deferred license revenue. The amounts received from Wanbang Biopharmaceuticals Co., Ltd. (“Wanbang”), Sun Pharmaceutical Industries Ltd. ("Sun Pharma"), Jeil Pharmaceutical Co., Ltd. ("Jeil Pharma") and Drogsan Pharmaceuticals ("Drogsan Pharma") are recognized as revenue over the estimated term of the applicable distribution and license agreement as regulatory approval was not received and the Company did not have sufficient experience in China, India, South Korea and Turkey, respectively, to determine that regulatory approval was probable as of the execution of the agreement. The amounts received from Baxter Healthcare Corporation (“Baxter”) were deferred and recognized as revenue at the point in time the estimated product sales under the agreement occurred. During the three months ended March 31, 2023, all remaining deferred revenue relating to the Baxter agreement was recognized as revenue. For additional information related to the Company's deferred license revenue, see Note 10.

Product Purchase Agreements

On September 18, 2023, the Company and its long-time partner, DaVita, Inc. ("DaVita"), a leading provider of kidney care, entered into an Amended and Restated Products Purchase Agreement (the "Amended Agreement"), which amends and restates the Product Purchase Agreement, dated July 1, 2019, as amended, under which the Company supplies DaVita with certain dialysis concentrates. Under the Amended Agreement, the Company and DaVita agreed to an increase in product pricing, effective September 1, 2023 and a one-time payment of $0.4 million to Rockwell on or after December 1, 2023, which was recorded as revenue recognized during the fourth quarter of 2023. The term of the Amended Agreement will expire on December 31, 2024. DaVita will have the right, in its sole discretion upon written notice to the Company given no later than September 30, 2024, to further extend the term through December 31, 2025. In the event of such an extension, product pricing will be increased for the extended term. In addition, DaVita is required to provide the Company with nine-month purchasing forecasts and a commitment to purchase at least the forecasted amounts. In the event that DaVita does not meet its forecasts, it is required to pay the Company for the amount forecasted or purchase additional product; otherwise, the Company may terminate the Amended Agreement. Upon expiration or termination of the Amended Agreement, and upon request by DaVita, the Company has agreed it would provide transition services to DaVita during a transition period.

Disaggregation of revenue

Revenue is disaggregated by primary geographical market, major product line, and timing of revenue recognition.

Contract balances

The following table provides information about receivables, contract assets, and contract liabilities from contracts with customers.

There wereno other material contract assets recorded on the condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023. The Company does not generally accept returns of its concentrate products andno material reserve for returns of concentrates products was established as of March 31, 2024 or December 31, 2023.

The contract liabilities primarily relate to upfront fees under distribution and license agreements with Wanbang, Sun Pharma, Jeil Pharma, and Drogsan Pharma.

Transaction price allocated to remaining performance obligations

For the three months ended March 31, 2024 and 2023, the Company recognized an immaterial amount and $1.5 million as revenue from amounts classified as contract liabilities (i.e., deferred license revenue) as of December 31, 2023 and 2022, respectively.

Revenue expected to be recognized in any future year related to remaining performance obligations, excluding revenue pertaining to contracts that have an original expected duration of one year or less, contracts where revenue is recognized as invoiced and contracts with variable consideration related to undelivered performance obligations, totaled $0.5 million as of March 31, 2024. The amount relates primarily to upfront payments and consideration received from customers that are received in advance of the customer assuming control of the related products. The Company applies the practical expedient in ASC 606, paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less.

6. Investments - Available-for-Sale

Investments available-for-sale consisted of the following as of March 31, 2024 and December 31, 2023 (table in thousands):

The fair value of investments available-for-sale are determined using quoted market prices from daily exchange-traded markets based on the closing price as of the balance sheet date and are classified as a Level 1 measurement under ASC 820 Fair Value Measurements.

As of March 31, 2024 and December 31, 2023, our available-for-sale securities were all due within one year.

7. Inventory

Components of inventory, net of reserves, as of March 31, 2024 and December 31, 2023 are as follows (table in thousands):

10. Deferred License Revenue

In October 2014, the Company entered into an exclusive distribution agreement with Baxter, which had a term of 10 years and received an upfront fee of $20 million. Under the exclusive distribution agreement, Baxter distributed and commercialized Rockwell’s hemodialysis concentrates products and provided customer service and order delivery to nearly all U.S. customers. The upfront fee was recorded as deferred license revenue and was being recognized based on the proportion of product shipments to Baxter in each period, compared with total expected sales volume over the term of the distribution agreement. On November 9, 2022, Rockwell paid Baxter a fee, which was reflected as a reduction to revenue on the consolidated statements of operations, and was payable intwo equal installments on January 1, 2023 and April 1, 2023, to reacquire its distribution rights to its hemodialysis concentrates products from Baxter and terminated the distribution agreement. Exclusivity and other provisions associated with the distribution agreement terminated November 9, 2022 and the remaining operational elements of the agreement terminated December 31, 2022. To ensure that customer needs continued to be met after January 1, 2023, Rockwell agreed to provide certain services to a group of Baxter's customers until March 31, 2023, and Baxter and Rockwell worked together to transition customers’ purchases of Rockwell’s hemodialysis concentrates through that date. Following the reacquisition of these rights, Rockwell is now unrestricted in its ability to sell its hemodialysis concentrates products to dialysis clinics throughout the United States and around the world. The Company recognized the remaining revenue of $1.5 million during the three months ended March 31, 2023.

The remaining agreements with Sun Pharma, Jeil Pharmaceutical, and Drogsan Pharmaceuticals comprise the current and long-term portions of deferred license revenue on the condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023.

11. Stockholders’ Equity

Preferred Stock

On April 6, 2022, the Company and DaVita entered into the Securities Purchase Agreement (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 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. As of March 31, 2024, the Series X Preferred Stock accreted a total $0.2 million.

The Series X Convertible Preferred Stock is convertible to common stock at a 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 and the sale of the assets that would allow for redemption is within the control of the Company, 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 mandatory redemption definition which could trigger liability classification.

As of each of March 31, 2024 and December 31, 2023, there were 2,000,000 shares of preferred stock, $0.0001 par value per share, authorized and 15,000 shares of preferred stock issued and outstanding.

Common Stock

During the three months ended March 31, 2024 and 2023, no vested employee stock options were exercised.

Controlled Equity Offering

On April 8, 2022, the Company entered into the Sales Agreement (the "ATM facility") with Cantor Fitzgerald & Co. as Agent, pursuant to which the Company may offer and sell from time to time up to $12.2 million 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.

During the three months ended March 31, 2024,358,210 shares were sold pursuant to the Sales Agreement for net proceeds of $0.6 million. Approximately $10.4 million remains available for sale under the ATM facility.

Private Placement

On July 10, 2023, the Company entered into a letter agreement (the “Letter Agreement”) with Armistice Capital Master Fund Ltd. (“Armistice”), which held a warrant (the “Prior Warrant”) to purchase 9,900,990 shares of common stock of the Company (the “Common Stock”) with an exercise price of $1.39 per share, offering Armistice the opportunity to exercise the Prior Warrant for cash, provided the Prior Warrant was exercised for cash on or prior to 5:00 P.M. Eastern Time on July 10, 2028 (the “End Date”). In addition, Armistice would receive a “reload” warrant (the “Reload Warrant”) to purchase 3,750,000 shares of Common Stock with an exercise price of $5.13 per share, the closing price as reported by the Nasdaq Capital Market on July 7, 2023. The terms of the Reload Warrant and Letter Agreement provide for customary resale registration rights. The Letter Agreement also provides that for a period of 45 days after the issuance of the Reload Warrant, the Company’s may not sell shares of Common Stock pursuant to its sales agreement with Cantor Fitzgerald & Co., dated as of April 8, 2022, at price per share less than $6.25. The Reload Warrant may be exercised at all times prior to the 54 months month anniversary of its issuance date. The Prior Warrant and the Reload Warrant both provide that a holder (together with its affiliates) may not exercise any portion of the Prior Warrant or the Reload Warrant to the extent that 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 such warrant. To the extent the exercise of the Prior Warrant would result in Armistice holding more than 9.99% of the Company’s outstanding Common Stock, such shares of Common Stock in excess of 9.99% will be held in abeyance. The Letter

Agreement amended the Prior Warrant to extend the expiration date thereof toone year following the original expiration date set forth therein.

Armistice exercised the Prior Warrant on July 10, 2023, and the Company received gross proceeds of approximately $13.8 million.

Third Amendment

In connection with the execution of the Third Amendment, as defined and described in Note 15, on January 2, 2024, the Company issued to Innovatus a warrant to purchase 191,096 shares of the Company’s common stock with an exercise price of $1.83 per share. The warrant may be exercised on a cashless basis, and is immediately exercisable through January 2, 2029. The number of shares of common stock for which the warrant is exercisable and the exercise price are subject to certain proportional adjustments as set forth in the Third Amendment. The warrant is equity-classified with a fair value of approximately $0.2 million at issuance, which was treated as a debt issuance cost and will be amortized through interest expense over the remaining contractual term of the Term Loan.

The fair value of the warrant at the issuance date was calculated using the Black-Scholes pricing model and include the following assumptions:

15. Loan and Security Agreement

On March 16, 2020, the Company and Rockwell Transportation, Inc., as Borrowers, entered into a Loan and Security Agreement (the "Loan Agreement") with Innovatus Life Sciences Lending Fund I, LP ("Innovatus"), as collateral agent and the lenders party thereto, pursuant to which Innovatus, as a lender, agreed to make certain term loans to the Company in the aggregate principal amount of up to $35.0 million (the "Term Loans"). Funding of the first $22.5 million tranche was completed on March 16, 2020. The Company is no longer eligible to draw on additional tranches, which were tied to the achievement of certain milestones. Net draw down proceeds were $21.2 million with closing costs of $1.3 million. The Company also owes an additional fee equal to 4.375% of the funded amount of the Term Loans, or $1.0 million (such additional fee, the "Final Fee") at

maturity. The Company is accreting up to this Final Fee premium with a charge against interest expense on the accompanying condensed consolidated statements of operations.

In connection with each funding of the Term Loans, the Company was required to issue to Innovatus a warrant (the “Warrants”) to purchase a number of shares of the Company’s common stock equal to 3.5% of the principal amount of the relevant Term Loan funded divided by the exercise price. In connection with the first tranche of the Term Loans, the Company issued a Warrant to Innovatus, exercisable for an aggregate of 43,388 shares of the Company’s common stock at an exercise price of $18.15 per share. The Warrant may be exercised on a cashless basis and is immediately exercisable through the seventh anniversary of the applicable funding date. The number of shares of common stock for which the Warrant is exercisable and the associated exercise price are subject to certain proportional adjustments as set forth in such Warrant. The Company evaluated the warrant under ASC 470, Debt, and recognized an additional debt discount of approximately $0.5 million based on the relative fair value of the base instruments and warrants. The Company calculated the fair value of the warrant using the Black-Scholes model.

The Term Loan was scheduled to mature on March 16, 2025, and bore interest at the greater of (i) Prime Rate (as defined in the Loan Agreement) and (ii)4.75%, plus 4.00%, with an initial interest rate of 8.75% per annum. The Company had the option, under certain circumstances, to add 1.00% of such interest rate amount to the then outstanding principal balance in lieu of paying such amount in cash.

The Loan Agreement is secured by all assets of the Company and Rockwell Transportation, Inc. and contains customary representations and warranties and covenants, subject to customary carve outs, and initially included financial covenants related to liquidity and sales of Triferic.

In September 2021, the Company entered into an amendment to the Loan Agreement in which the Company, in exchange for Innovatus lowering the sales covenants, agreed to: (i) prepay an aggregate principal amount of $7.5 million inten installments commencing on December 1, 2021; (ii) pay an additional prepayment premium of 5% on prepaid amounts if the Company elects to prepay all outstanding Term Loans on or before September 24, 2023; and (iii) maintain minimum liquidity of no less than $5.0 million if the aggregate principal amount of Term Loans is greater than $15 million pursuant to the liquidity covenant in the Loan Agreement.

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. Pursuant to the Second Amendment, the Company (i) prepaid an additional aggregate principal amount of $5.0 million in Term Loans in one installment on November 14, 2022; and (ii) paid interest only payments until September 2023, at which time it resumed scheduled debt payments. The financial covenant related to the sales of Triferic was replaced with the trailing 6 months revenue of the Company's concentrates products.

On January 2, 2024, the Company entered into the Third Amendment to and Restatement of the Loan and Security Agreement (the "Third Amendment") with Innovatus, dated January 1, 2024. The Third Amendment provides for the continuation of term loans initially borrowed under the Loan Agreement amounting to $8.0 million as of January 1, 2024. The Company will make interest-only payments on the Term Loans for 30 months, or up to 36 months if certain conditions are met. The Term Loans will mature on January 1, 2029, unless earlier repaid. Effective on January 1, 2024, the Term Loans will bear interest equal to the sum of (i) the greater of (a) Prime Rate (as defined in the Third Amendment) and (b)7.50% plus (ii)3.50%. At the Company's option,2.00% of the interest due on any applicable interest payment date during the interest-only period may be paid in-kind by adding such amount to the then outstanding principal balance of the Term Loans. The Term Loans may be voluntarily prepaid in full (but not partially) at any time, upon at least seven business days’ prior notice. In connection with any voluntary prepayment or satisfaction of the Term Loans prior to the maturity date (including any acceleration), the Company will pay all accrued and unpaid interest and all other amounts due in connection with the Term Loans, together with (x) a prepayment fee (the “Prepayment Fee”) equal to: (i)6.0% of the principal amount of the Term Loans prepaid if the payment is made before January 1, 2025; (ii)2.0% of the principal amount of the Term Loans prepaid if the payment is made after January 1, 2025 but on or before January 1, 2026; (iii)1.0% of the principal amount of the Term Loans prepaid if the payment is made after January 1, 2026 but on or before January 1, 2027; or (iv)0% of the principal amount of the Term Loans prepaid if the payment is made after January 1, 2027 through maturity, and (y) the Final Fee. The Term Loans will be mandatorily prepaid upon a change in control of the Company, or upon any early termination/acceleration of the Term Loans. In the event of a mandatory prepayment of the Term Loans, the Company shall be required to pay the Prepayment Fee (if applicable), as well as the Final Fee. The Third Amendment Final Fee shall be due and payable at maturity if it has not previously been paid in full in connection with a prepayment of the Term Loans. The Third Amendment was treated as a modification for accounting purposes.

The Third Amendment contains various financial covenants and customary representations and warranties and affirmative and negative covenants, subject to exceptions as described in the Third Amendment. The Company's ability to comply with the covenants under the Third Amendment may be adversely affected by events beyond its control. If the Company is unable to comply with the covenants under the Third Amendment, it would pursue all available cure options in order to regain compliance. However, the Company may not be able to mutually agree with Innovatus on appropriate remedies to cure a future breach of a covenant, which could give rise to an event of default. However, as of March 31, 2024, the Company was in compliance with all covenants under the Third Amendment.

In connection with the execution of the Third Amendment, on January 2, 2024, the Company issued a warrant to purchase shares of the Company’s common stock. The warrant is equity-classified with a fair value of $0.2 million at issuance, which was treated as a debt issuance cost and will be amortized through interest expense over the remaining contractual term of the Term Loan. For additional information, see Note 11.

The effective interest rate is 12.0% as of March 31, 2024. For the three months ended March 31, 2024 and 2023, interest expense amounted to $0.2 million and $0.4 million, respectively. As of March 31, 2024, the outstanding balance of the Term Loan was $8.3 million, net of unamortized issuance costs and discount of $0.7 million, and including $0.8 million of premium accretion, $0.1 million related to a fee resulting from the Third Amendment, and paid-in-kind interest of $40 thousand.

The following table reflects the schedule of principal payments on the Term Loan as of March 31, 2024 (in thousands):
