This document contains forward-looking statements that are based on current expectations, estimates, forecasts and projections about the industries in which Diasorin operates and the beliefs and assumptions of the management of Diasorin. In addition, the management of Diasorin may make forward-looking statements orally to analysts, investors, representatives of the media and others. In particular, among other statements, certain statements regarding future financial performance, the achievement of certain targeted metrics at any future date or for any future period, trends in results of operations, margins, costs, return on capital, risk management and competition are forward-looking in nature. These statements may include terms such as "may", "will", "expect", "could", "should", "intend", "estimate", "anticipate", "believe", "remain", "on track", "design", "target", "objective", "goal", "forecast", "projection", "outlook", "prospects", "plan", or similar terms. Forward-looking statements are not guarantees of future performance and are, by their nature, subject to inherent risks, uncertainties and assumptions that are difficult to predict because they relate to events and depend on circumstances that may or may not occur or exist in the future and, as such, undue reliance should not be placed on them.
Forward-looking statements do not take into account any additional effects that may arise from impacts on the global market in which Diasorin operates and, more generally, on the macroeconomic scenario.
Actual results may differ materially from those expressed in forward-looking statements as a result of a variety of factors, including: the impact of the COVID-19 pandemic, the ability of the Group to create and launch new products successfully; changes in the global financial markets, general economic environment and changes in demand for diagnostic/healthcare/life sciences products, which is subject to cyclicality; changes in local economic and political conditions, changes in trade policy and the imposition of global and regional tariffs or tariffs targeted to the diagnostic/healthcare/life sciences industry, the enactment of tax reforms or other changes in tax laws and regulations; the Group's ability to offer innovative, attractive products; various types of claims, lawsuits, governmental investigations and other contingencies, including product liability and warranty claims, investigations and lawsuits; material operating expenditures in relation to compliance with health and safety regulations; the intense level of competition in the diagnostic/healthcare/life sciences industry, which may increase due to consolidation; the Group's ability to fund its defined benefit pension plans; the ability to access funding to execute the its business plans and improve its own businesses, financial condition and results of operations; the Group's ability to realize anticipated benefits from joint venture arrangements; disruptions arising from political, social and economic instability; commercial risk due the fact that the Group operates in a market characterized by the presence of large competitors; risk associated to the maintenance of relationship with customers and strategic partners; risks associated with relationships with employees and suppliers; increases in costs, disruptions of supply or shortages of raw materials; developments in labor and industrial relations and developments in applicable labor laws; exchange rate fluctuations, interest rate changes, credit risk and other market risks; political and civil unrest; earthquakes or other disasters.
Any forward-looking statements contained in this document speak only as of the date of this document and Diasorin disclaim any obligation to update or revise publicly forward-looking statements. Further information concerning the Group and its business, including factors that could materially affect the Group's financial results, are included in Diasorin'sreports and filings with CONSOB and Borsa Italiana.

The information and opinions in this document is provided to you as of the dates indicated and Diasorin does not undertake to update the information contained in this document and/or any opinions expressed relating thereto after its presentation, even in the event that the information becomes materially inaccurate, except as otherwise required by applicable laws.
Non-IFRS and Other Performance Measures. This document contains certain items as part of the financial disclosure, which are not defined under IFRS. Accordingly, these items do not have standardized meanings and may not be directly comparable to similarly-titled items adopted by other entities. Diasorin management has identified a number of "Alternative Performance Indicators" ("APIs"). These APIs (i) are derived from historical results of Diasorin and are not intended to be indicative of future performance, (ii) are non-IFRS financial measures and, although derived from the financial statements, are unaudited and (iii) are not an alternative to financial measures prepared in accordance with IFRS. The APIs presented herein include EBITa , EBITDAb , adjusted EBITDAc , Net Financial Positiond and Free Cash Flowe . These measures are not indicative of historical operating results, nor are they meant to be predictive of future results. These measures are used by the management to monitor the underlying performance of the business and operations. Similarly entitled non-IFRS financial measures reported by other companies may not be calculated in an identical manner, consequently the measures reported in this document may not be consistent with similar measures used by other companies. Therefore, investors should not place undue reliance on this data.
a EBIT is defined as the "Operating Result" net of interests and taxes – b EBITDA is defined as the "Operating Result", gross of amortization and depreciation of intangible and tangible asset. EBITDA is a measure used by the Company to monitor and evaluate the Group's operating performance and is not defined as an accounting measure in IFRS therefore shall be considered an alternative measure for assessing the Group's operating result performance. c Adjusted EBITDA is defined as Adjusted EBITDA, excluding extraordinary costs and expenses incurred in the Luminex transaction announced on April 11, 2021 d The Net Financial Position is defined as the algebraic sum (positive balance sheet assets and negative balance sheet liabilities) of cash and cash equivalents and other current financial assets, minus current financial liabilities and non-current financial liabilities. e Free Cash Flow is defined as the set of means available to the Company and is equal to cash flows deriving from operating activities net of interest received or paid, and net of investments and divestments of fixed assets.
