On May 5, 2026, Fresenius Medical Care AG (the “Company”) issued a Press Release announcing its first quarter results for the period ending March 31, 2026. A copy of the Press Release is furnished as Exhibit 99.1 and the corresponding financial figures as Exhibit 99.2.

The attached Press Release contains non-GAAP financial measures. For purposes of Regulation G, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles. To supplement our first quarter 2026 consolidated financial results presented in accordance with International Financial Reporting Standards, or IFRS, we have used non-GAAP financial measures, including (a) EBITDA, or operating income excluding interest, taxes, depreciation and amortization, (b) free cash flow, (c) net leverage ratio (ratio of net debt to adjusted EBITDA) and (d) results presented in constant currency and as adjusted for special items identified in the Press Release and associated tables. These non-GAAP measures are provided to enhance the user’s overall understanding of our current financial performance and our prospects for the future. In addition, because we have historically reported certain non-GAAP financial measures in our financial results, we believe the inclusion of these non-IFRS financial measures provides consistency and comparability in our financial reporting to prior periods for which these non-GAAP financial measures were previously reported. These non-GAAP financial measures should not be used as a substitute for or be considered superior to GAAP financial measures. Reconciliation of the non-GAAP financial measures to the most comparable IFRS financial measures are included in the attached Financial Statements. As the reconciliation of amounts stated in Constant Currency is inherent in the disclosure included in the Press Release, we believe that a separate reconciliation would not provide any additional benefit.

The Exhibits attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities and Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, regardless of any general incorporation language in such filing.
