Rhea-AI Filing Summary

Rockwell Medical, Inc. reported fourth quarter and full-year 2025 results showing a sharp revenue decline but improved margins and positive cash generation. Net sales were $18.3 million in Q4 2025 versus $24.7 million a year earlier, and $69.3 million for 2025 compared with $101.5 million in 2024, mainly due to lower purchase volume from one customer.

Q4 2025 gross margin improved to 21% from 15%, with full-year 2025 gross margin steady at 17%. The company posted a 2025 net loss of $5.3 million versus $0.5 million in 2024, but remained profitable on an Adjusted EBITDA basis at $0.3 million. Cash, cash equivalents and investments were $25.0 million at December 31, 2025, up from $21.6 million. For 2026, Rockwell guides to Adjusted EBITDA of $1 million to $2 million and positive operating cash flow.

Positive

  • Margin and cash strength despite lower sales: Q4 2025 gross margin rose to 21% from 15%, full-year margin held at 17%, Adjusted EBITDA remained positive at $0.3 million, and cash and investments increased to $25.0 million with lower total liabilities.
  • Improved commercial footing and pricing: The company extended a major U.S. dialysis provider agreement through December 31, 2026 with higher product pricing and added 30 new western U.S. customers, with that region now exceeding 10% of its clinic footprint.

Negative

  • Significant revenue and earnings deterioration: 2025 net sales fell to $69.3 million from $101.5 million and net loss widened to $5.3 million from $0.5 million, while Adjusted EBITDA declined to $0.3 million from $5.0 million, reflecting volume reduction from a key customer.

Insights

Revenue fell sharply but margins, cash, and guidance show a stabilizing, profit-focused profile.

Rockwell Medical saw net sales drop to $69.3 million in 2025 from $101.5 million in 2024, driven by reduced volume from a single customer. Despite this, gross margin held at 17% for the year, with Q4 margin rising to 21%, reflecting cost and infrastructure adjustments.

The company stayed profitable on an Adjusted EBITDA basis, though that metric declined to $0.3 million in 2025 from $5.0 million in 2024. Cash and investments increased to $25.0 million, while liabilities fell, suggesting a stronger balance sheet despite the higher net loss, which included $4.0 million in non-cash items and $1.2 million in severance and transition costs.

Management extended a key products purchase agreement through December 31, 2026 with improved pricing and added customers in the western U.S., now over 10% of its clinic footprint. For 2026, guidance of $1 million to $2 million Adjusted EBITDA and positive operating cash flow indicates an emphasis on sustainable profitability while negotiations with several large customers could later shape net sales and gross margin expectations.

Rockwell Medical Announces Fourth Quarter and Full-Year 2025
Financial and Operational Results

Net sales for the fourth quarter and full-year 2025 were $18.3 million and $69.3 million, respectively.

Achieved profitability on an Adjusted EBITDA basis for the second consecutive year in 2025.

Generated 21% in gross margin for the fourth quarter 2025, representing one of the strongest quarters for gross margin in the Company's history and a meaningful improvement over 15% gross margin for the same period in 2024.

Reported $2.3 million in cash flow from operating activities in the fourth quarter 2025, which increased the Company's cash position at year-end 2025 to $25.0 million.


Wixom, Michigan, March 26, 2026 – 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 and twelve months ended December 31, 2025.

"2025 was a year of transition for Rockwell Medical. We successfully navigated changes in our customer base, purchase volumes, and distribution footprint, all while maintaining profitability on an Adjusted EBITDA basis for the second consecutive year," said Mark Strobeck, Ph.D., President and CEO of Rockwell Medical. "We made significant changes internally to further align our infrastructure with demand. As a result, our gross margin for the full-year 2025 was in line with gross margin for 2024, and we delivered one of the highest quarterly gross margins in the Company's history in the fourth quarter 2025. Additionally, in the fourth quarter 2025, we generated positive cash flow from operating activities resulting in a higher cash position at year-end. We remain focused on making Rockwell Medical consistently profitable and positioning the Company for long-term stability and success. In 2026, we believe we are well-positioned to build upon this momentum with a clear focus on driving revenue growth, expanding profitability, and further diversifying our portfolio."

FOURTH QUARTER AND FULL-YEAR 2025 OPERATING HIGHLIGHTS

In December 2025, we extended our Amended and Restated Products Purchase Agreement (the "Amended Agreement") dated September 18, 2023 with one of the largest dialysis providers in the United States through December 31, 2026. As part of the Amended Agreement, product pricing will be increased for the extended term.

In November 2025, Joe Dawson was appointed to the Company's board of directors.

In November 2025, Rashad Brown was named Vice President, Manufacturing and Supply Chain.

In the fourth quarter of 2025, we added 30 new customers in the western portion of the United States. With our expanded distribution capabilities, we are now a viable alternative supplier in the western U.S. and are able to more efficiently deliver hemodialysis concentrates products to our existing customers with facilities in that region. The western U.S. now accounts for more than 10% of our customer clinic footprint.

In September 2025, Heather Hunter was promoted to Chief Operating Officer.

In July 2025, Rockwell Medical signed a multi-year product purchase agreement with Innovative Renal Care, one of the largest dialysis service providers in the United States.

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.

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. We believe that Adjusted EBITDA is our best proxy for cash burn.

Adjusted EBITDA 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 as a tool for comparison. There are a number of limitations related to the use of these non-GAAP financial measures rather than net loss, which is the most directly comparable financial measure calculated in accordance with GAAP. When evaluating the Company’s performance, you should consider Adjusted EBITDA alongside other financial performance measures, including net loss and other GAAP results.
