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 provides 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 measure 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.
