Forward-looking statements are often identified by the use of words such as, but not limited to, “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “will,” “plan,” “project,” “seek,” “should,” “target,” “will,” “would,” and similar expressions or variations intended to identify forward-looking statements. All statements, other than statements of historical facts, regarding management’s expectations, beliefs, goals, plans or CorMedix’s prospects should be considered forward-looking statements, including, but not limited to statements regarding Melinta providing an attractive revenue base of highly synergistic assets with multiple opportunities to drive future growth; financial guidance, peak annual sales estimates, synergy estimates and timing, accretion estimates, and EBITDA or Adjusted EBITDA estimates. Readers are cautioned that actual results may differ materially from projections or estimates due to a variety of important factors, and readers are directed to the Risk Factors identified in CorMedix’s filings with the SEC, including its most recent Annual Report on Form 10-K, copies of which are available free of charge at the SEC’s website at www.sec.gov or upon request from CorMedix and in the Quarterly Report on Form 10-Q for the quarter ended, on June 30, 2025. CorMedix may not actually achieve the goals or plans described in its forward-looking statements, and such forward-looking statements speak only as of the date of this press release. Investors should not place undue reliance on these statements. CorMedix assumes no obligation and does not intend to update these forward-looking statements, except as required by law. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. Actual outcomes or results may differ from anticipated results, sometimes materially. Factors that could cause actual results to differ include, but are not limited to: the ability to integrate the Melinta business into CorMedix and realize the anticipated strategic benefits of the transaction within the expected time-frames or at all; that such integration may be more difficult, time-consuming or costly than expected; the ability of the combined company to achieve the identified synergies; that operating costs, customer loss and business disruption (including, without limitation, difficulties in maintaining relationships with employees, customers or suppliers) may be greater than expected following the transaction; the retention of certain key employees; the expected benefits and success of Melinta’s products and product candidates; potential litigation relating to the transaction that could be instituted against CorMedix or its directors; rating agency actions and CorMedix’s ability to access short- and long-term debt markets on a timely and affordable basis; general economic conditions that are less favorable than expected; geopolitical developments and additional changes in international trade policies and relations, including tariffs; and the ability of our products and product candidates to compete effectively against current and future competitors. Non-GAAP Financial Measures This release includes certain non-GAAP financial measures, including Adjusted EBITDA, which are intended as supplemental measures of CorMedix’s performance that are not required by or presented in accordance with GAAP. Management uses these non-GAAP measures internally to evaluate and manage CorMedix’s operations and to better understand its business because they facilitate a comparative assessment of CorMedix’s operating performance relative to its performance based on results calculated under GAAP. These non-GAAP measures also isolate the effects of some items that vary from period to period without any correlation to core operating performance and eliminate certain charges that management believes do not reflect CorMedix’s operations and underlying operational performance. CorMedix believes that these non-GAAP measures also provide useful information to investors regarding certain financial and business trends relating to CorMedix’s financial condition and operating results and facilitate an evaluation of the financial performance of CorMedix and its operations on a consistent basis. Providing this information therefore allows investors to make independent assessments of CorMedix’s financial performance, results of operations and trends while viewing the information through the eyes of management. These non-GAAP measures are subject to limitations. The non-GAAP measures presented in this release may not be comparable to similarly titled measures used by other companies because other companies may not calculate one or more in the same manner. Additionally, the non-GAAP performance measures exclude significant expenses and income that are required by GAAP to be recorded in CorMedix’s financial statements; do not reflect changes in, or cash requirements for, working capital needs. Further, our historical adjusted results are not intended to project our adjusted results of operations or financial position for any future period. To compensate for these limitations, management presents and considers these non-GAAP measures in conjunction with CorMedix’s GAAP results; no non-GAAP measure should be considered in isolation from or as alternatives to any measure determined in accordance with GAAP. Readers should review the reconciliations included below, and should not rely on any single financial measure to evaluate CorMedix’s business. Adjusted EBITDA is a non-GAAP financial measure and excludes non-cash items such as stock based compensation and certain non-recurring items. See CorMedix’s earnings release dated August 7, 2025 for further information. Pro forma 2025 Synergized Adjusted EBITDA and Pro Forma 2025 Revenue were prepared by combining the estimated financial results and guidance for CorMedix and Melinta for the full fiscal year ended December 31, 2025, without further adjustment, and taking into account 100% realization of expected synergies and full year run-rate of estimated synergies (as if the transaction had closed on January 1, 2025). As a result, we believe this pro forma financial information includes non-GAAP financial measures. CorMedix has not provided a reconciliation to the most directly comparable GAAP measures because certain items needed to make a reasonable forward-looking estimate of the comparable GAAP measures cannot be reasonably calculated or predicted at this time. Accordingly, a reconciliation is not available without unreasonable effort. Pro forma financial information does not necessarily reflect the actual results that we would have achieved had the pro forma transaction been consummated as of the date indicated nor does it reflect the potential future results of the combined company. Our forward-looking estimates of both GAAP and non-GAAP measures of our financial performance may differ materially from our actual results and should not be relied upon as statements of fact.
