WIXOM, Mich. / May 12, 2025 / 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, 2025.

"During the first quarter, we continued to diversify our customer base with some of the leading regional, national and global hemodialysis providers and health systems. We remain a preferred provider as a result of our continued reliability, high-quality products, and customer-centric approach," said Mark Strobeck, Ph.D., Rockwell Medical’s President and CEO. "Additionally, we continued to consolidate and further automate our manufacturing operations to reduce expenses and sustain our gross margin despite our largest customer moving away from Rockwell Medical. We look forward to sharing more updates in the months ahead."

FIRST QUARTER 2025 FINANCIAL HIGHLIGHTS

• Net sales for the three months ended March 31, 2025 were $18.9 million, which represents a 17% decrease over net sales of $22.7 million for the same period in 2024. The decrease in net sales was driven by the Company's largest customer transitioning to another supplier. Subject to further discussions, this customer agreed to a one-time, non-refundable payment of $0.9 million, which was recognized in the first quarter, to ensure continuity of supply for products purchased during the first quarter 2025.
• Gross profit for the three months ended March 31, 2025 was $3.0 million, which was in line with gross profit for the same period in 2024.
• Gross margin for the three months ended March 31, 2025 was 16%, representing an increase from 14% for the same period in 2024.
• Net loss for the three months ended March 31, 2025 was $1.5 million, representing a 12% improvement over a net loss of $1.7 million for the same period in 2024.
• Adjusted EBITDA for the three months ended March 31, 2025 was ($0.4) million. Seasonal items associated with payroll tax and other public company related expenses historically incurred in the first quarter drove the Company's adjusted EBITDA to be slightly negative.
• Cash and cash equivalents and investments available-for-sale at March 31, 2025 was $17.3 million compared to cash and cash equivalents and investments available-for-sale of $21.6 million at December 31, 2024. The decrease in cash of approximately $4.3 million was driven by timing of payments and collections and seasonal items historically incurred in the first quarter.

FIRST QUARTER 2025 OPERATING HIGHLIGHTS

• Rockwell Medical added a single-use bicarbonate cartridge to its hemodialysis concentrates product portfolio through a distribution services agreement with a leading manufacturer of medical equipment including hemodialysis machines, disposable products, and automated fluid balance systems.

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. In addition, this press release includes a reference to adjusted EPS, a non-GAAP financial measure that is defined as adjusted EBITDA divided by the weighted average number of shares outstanding. The Company has also provided a reconciliation to EPS, or net income divided by the weighted average number of shares outstanding, which is the most directly comparable GAAP financial measure. 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 and adjusted EPS are key measures 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 provide useful measures for period-to-period comparisons of Rockwell Medical’s business. This is also true for adjusted EPS, which is derived from adjusted EBITDA.

Adjusted EBITDA and adjusted EPS 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 EPS 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 EPS alongside other financial performance measures, including net loss, EPS and other GAAP results.
