CorMedix announced in early February that its Board of Directors approved a share repurchase program, which authorizes the Company to repurchase up to $75 million of the Company’s outstanding common stock. As highlighted during the Company’s recent Analyst Day, CorMedix expects clinical data from the Phase 3 ReSPECT study of REZZAYO® (rezafungin for injection) in the prophylaxis of invasive fungal infections in adult patients undergoing allogeneic blood and marrow transplant in Q2 2026. In addition, the ongoing Phase 3 study of taurolidine/heparin catheter lock solution in TPN patients continues to enroll patients with targeted completion in the first half of 2027. Cash and short-term investments, excluding restricted cash, at December 31, 2025 amounted to $148.5 million. Joe Todisco, CorMedix Chairman and CEO, commented, “I am proud of the Company’s progress over the past year as we have accelerated the expansion of patient access for DefenCath, completed our acquisition and integration of Melinta, and saw progress in our two ongoing Phase 3 clinical programs for Rezzayo prophylaxis and DefenCath in TPN. With the announcement of our share repurchase program and multiple near-term milestones on the horizon, most notably the Rezzayo ReSPECT phase III data, CorMedix is focused on driving business growth and shareholder value over the year ahead.” Fourth Quarter and Full Year 2025 Financial Highlights For the fourth quarter of 2025, CorMedix recorded $128.6 million in net revenue, comprised of $91.2 million in sales of DefenCath and $37.4 million in revenue associated with the Melinta portfolio, an increase from $31.2 million in net revenue in the comparable period of 2024. The fourth quarter of 2025 was the first full quarter of Melinta portfolio revenue after the closing of the acquisition in August 2025. Total operating expenses in the fourth quarter of 2025 were $48.2 million, compared with $17.1 million in the fourth quarter of 2024, an increase of approximately 182%. The increase of $31.1 million over the prior period was driven primarily by the contribution of operating expenses from the Melinta acquisition for the full quarter. Fourth quarter 2025 operating expenses also included $4.1 million of non-recurring costs, including severance and other integration-related costs associated with the Melinta acquisition. Other drivers of increases year-over-year include stock-based compensation and investment in research and development programs associated with expanded indications for DefenCath, including the Phase III clinical study for prevention of CLABSI in TPN. For the fourth quarter of 2025, the Company recorded $14.0 million in net income, or $0.16 per diluted share, compared with net income of $13.5 million, or $0.20 per diluted share, in the fourth quarter of 2024. Net income for the fourth quarter of 2025 included tax expense, primarily associated with the utilization of the Company’s deferred tax assets, of $42.4 million. These deferred tax assets were established in the third quarter of 2025 and are associated with the anticipated future use of CorMedix Net Operating Loss (NOL) carryforwards due to projected future sustained profitability of the Company. Also for the fourth quarter of 2025, CorMedix reported Adjusted EBITDA of $77.2 million, compared to adjusted EBITDA of $15.3 million in the fourth quarter of 2024. For the year ended December 31, 2025, CorMedix recorded $311.7 million in total revenue, including $258.8 million in net sales of DefenCath and $52.9 million in net revenue from the legacy Melinta portfolio. Pro forma 2025 revenue, which reflects full-year revenue from the Melinta portfolio in addition to full-year net sales of DefenCath, was $401.3 million. The Company reported net income of $163.0 million, or $2.04 per diluted share, compared with a net loss of $17.9 million, or ($0.30) per share, in 2024. Net income was driven primarily by an increase in sales of DefenCath, and, to a lesser extent, net revenue from the acquisition of Melinta, partially offset by higher operating expenses. Operating expenses during the year ended December 31, 2025 totaled $125.6 million compared with $62.6 million for 2024, an increase of $63.0 million, or 101%. The increase over the prior year was driven primarily by the acquisition of Melinta, including the contribution of operating expenses from Melinta’s business for the period from August 29, 2025 through the end of the year as well as transaction, integration and severance costs. Other drivers of the year-over-year increase include stock-based compensation and investment in research and development programs associated with expanded indications for DefenCath, including the Phase III clinical study for prevention of CLABSI in TPN. The Company reported cash, cash equivalents and short-term investments of $148.5 million at December 31, 2025, excluding restricted cash. (1) Pro Forma Total Revenue was prepared by combining the financial results and for CorMedix and Melinta for the full fiscal year ended December 31, 2025, without further adjustment, as if the transaction had closed on January 1, 2025. (2) Adjusted EBITDA is a non-GAAP financial measure and excludes non-cash items such as depreciation, amortization, stock-based compensation, interest and other income and expense, taxes and certain non-recurring items.

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. In addition, 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.

Non-GAAP Financial Measures This release includes certain non-GAAP financial measures, including EBITDA and adjusted EBITDA, which are intended as supplemental measures of the Company’s performance that are not required by or presented in accordance with GAAP. Management uses these non-GAAP measures internally to evaluate and manage the Company’s operations and to better understand its business because they facilitate a comparative assessment of the Company’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 the Company’s operations and underlying operational performance. The Company believes that these non-GAAP measures also provide useful information to investors regarding certain financial and business trends relating to the Company’s financial condition and operating results, which facilitates an evaluation of the financial performance of the Company and its operations on a consistent basis. Providing this information therefore allows investors to make independent assessments of the Company’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 the Company’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 the Company’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 the Company’s business.
