WIXOM, Mich. / May 14, 2024 / Business Wire / Rockwell Medical, Inc. (the "Company") (Nasdaq: RMTI), a healthcare company that develops, manufactures, commercializes, and distributes a portfolio of hemodialysis products to dialysis providers worldwide, today announced financial and operational results for the three months ended March 31, 2024.

"We continue to see increasing interest in, and market demand for, our hemodialysis portfolio of products from medical equipment suppliers and distributors, along with health systems, dialysis centers, and skilled nursing facilities, domestically and internationally, all of which advances our vision to expand our global footprint and become the leading global supplier of all hemodialysis concentrates," said Mark Strobeck, Ph.D., Rockwell Medical’s President and CEO. "Taking into account our first quarter 2024 financial and operating results, we are pleased to announce that we have revised our guidance for 2024 upward and believe we are well-positioned to deliver on that guidance."

FIRST QUARTER 2024 FINANCIAL HIGHLIGHTS

Net sales for the three months ended March 31, 2024 consisted solely of concentrates products sales. Net sales for the three months ended March 31, 2023 consisted of sales of concentrates products and the recognition of $1.5 million of deferred license revenue related to the termination of the Baxter distribution agreement. The following first quarter year-over-year financial highlights illustrate the organic growth driven exclusively by the Company's hemodialysis concentrates products, particularly after excluding the impact of deferred revenue recognized in the first quarter of 2023.

• Net sales for the three months ended March 31, 2024 were $22.7 million, the highest quarterly concentrates products sales generated to date for the Company. This represents a 15% increase over net sales of $19.7 million for the same period in 2023. Excluding deferred revenue, net sales for the first quarter of 2024 increased 25% over the same period in 2023.
• Gross profit for the three months ended March 31, 2024 was $3.1 million, representing an 18% increase over $2.6 million for the same period in 2023. Excluding deferred revenue, gross profit of $3.1 million in the first quarter of 2024 nearly tripled from $1.1 million over the same period in 2023.
• Gross margin for the three months ended March 31, 2024 was 14%, representing an increase from 13% for the same period in 2023. Excluding deferred revenue, gross margin for the first quarter of 2024 approximately doubled from gross margin of 6% for the same period in 2023.
• Net loss for the three months ended March 31, 2024 was $1.7 million, representing a slight improvement over a net loss of $1.8 million for the same period in 2023. Excluding deferred revenue, net loss for the first quarter of 2024 improved by $1.5 million over a net loss of $3.2 million for the same period in 2023.
• Adjusted EBITDA for the three months ended March 31, 2024 was ($0.5) million. Seasonal items related to audit, payroll tax, and other public-company related expenses historically incurred in the first quarter drove the Company's Adjusted EBITDA to be slightly negative. The Company expects expenses to normalize for the remainder of 2024.
• Cash and cash equivalents and investments available-for-sale at March 31, 2023 was $8.6 million compared to cash and cash equivalents and investments available-for-sale of $10.9 million at December 31, 2023. The decrease in cash of approximately $2.3 million was driven by changes in working capital. At close-of-business on May 9, 2024, our cash and cash equivalents and investments available for sale was $10.2 million.
• During the first quarter of 2024, the Company amended its Loan and Security Agreement with Innovatus Life Sciences Lending Fund I, LP. Under the terms of the amendment, Rockwell Medical reduced the interest rate on the $8.0 million remaining balance of the loan and extended the loan maturity date from March 2025 to January 2029. The Company will now make interest-only payments through September 2026 and may extend the interest-only period through March 2027 if certain conditions are met.

NON-GAAP FINANCIAL MEASURES

To supplement Rockwell Medical’s unaudited condensed consolidated statements of operations and unaudited condensed consolidated balance sheets, which are prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”), this press release also includes references to Adjusted EBITDA, a non-GAAP financial measure that is defined as net income (loss) before net interest income (expense), net other income (expense), income tax expenses (benefit), depreciation and amortization, impairment charges, stock-based compensation expense, and other items that are considered unusual or not representative of underlying trends of our business, including but not limited to one-time severance costs, deferred revenue and inventory reserve amounts, if applicable for the periods presented. The Company has provided a reconciliation of net loss, the most directly comparable GAAP financial measure, to Adjusted EBITDA at the end of this press release. In addition, the Company has excluded deferred revenue from first quarter calculations of net sales, gross profit, gross margin and net loss. Each of these adjusted measures is a non-GAAP financial measure. The Company has provided reconciliations to the GAAP measures at the end of this press release.

Adjusted EBITDA is a key measure used by Rockwell Medical to understand and evaluate operating performance and trends, to prepare and approve its annual budget and to develop short- and long-term operating plans. The Company provides Adjusted EBITDA because it believes the metric is helpful in highlighting trends in its operating results because it excludes items that are not indicative of Rockwell Medical’s core operating performance. In particular, the Company believes that the exclusion of the items eliminated in calculating Adjusted EBITDA provides useful measures for period-to-period comparisons of Rockwell Medical’s business. Adjusted net sales, gross profit, gross margin and net loss is used by Rockwell Medical to understand growth within its hemodialysis concentrates business by excluding a one-time item that is not indicative of its core operating performance.

Adjusted EBITDA and adjusted net sales, gross profit, gross margin and net loss should not be considered in isolation of, or as an alternative to, measures prepared in accordance with GAAP. Other companies, including companies in the same industry, may calculate similarly titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of Adjusted EBITDA and adjusted net sales, gross profit, gross margin and net loss as tools for comparison. There are a number of limitations related to the use of these non-GAAP financial measures rather than the most directly comparable financial measures calculated in accordance with GAAP. When evaluating the Company’s performance, you should consider Adjusted EBITDA and adjusted net sales, gross profit, gross margin and net loss alongside other financial performance measures, including net loss and other GAAP results. Adjusted EBITDA is our best proxy for cash burn. Adjusted net sales, gross profit, gross margin and net loss enable us to understand growth within our hemodialysis concentrates business by excluding a one-time item that is not indicative of our core operating performance.
