Zegna Results Presentation Deck

DISCLAIMER Non-IFRS Financial Measures Ermenegildo Zegna Group Zegna's management monitors and evaluates operating and financial performance using several non-IFRS financial measures including: adjusted earnings before interest and taxes ("Adjusted EBIT"), Adjusted EBIT Margin, revenues on a constant currency basis (Constant Currency) and revenues on an organic growth basis (Organic Growth). Zegna's management believes that these non-IFRS financial measures provide useful and relevant information regarding Zegna's financial performance and financial condition, and improve the ability of management and investors to assess and compare the financial performance and financial position of Zegna with those of other companies. They also provide comparable measures that facilitate management's ability to identify operational trends, as well make decisions regarding future spending, resource allocations and other strategic and operational decisions. While similar measures are widely used in the industry in which Zegna operates, the financial measures that Zegna uses may not be comparable to other similarly named measures used by other companies nor are they intended to be substitutes for measures of financial performance or financial position as prepared in accordance with IFRS. Please see the Non-IFRS Financial Measures on Page 32 to 33 for Non-IFRS Measures definitions. Forward Looking Statements This communication, including the sections "Group Key Highlights" and "Outlook", contains forward-looking statements that are based on beliefs and assumptions and on information currently available to the Company. In some cases, you can identify forward-looking statements by the following words: "may," "will," "could," "would," "should," "expect," "intend," "plan," "anticipate," "believe," "estimate," "predict," "project," "potential," "continue," "ongoing," "target," "seek" or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, although not all forward-looking statements contain these words. Any statements that refer to expectations, projections or other characterizations of future events or circumstances, including strategies or plans, are also forward-looking statements. These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Although the Company believes that it has a reasonable basis for each forward-looking statement contained in this communication, the Company cautions you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. In addition, risks and uncertainties are described in the Company's filings with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Most of these factors are outside the Company's control and are difficult to predict. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by the Company and its directors, officers or employees or any other person that the Company will achieve its objectives and plans in any specified time frame, or at all. The forward-looking statements in this communication represent the views of Zegna as of the date of this communication. Subsequent events and developments may cause that view to change. However, while Zegna may elect to update these forward-looking statements at some point in the future, the Company disclaims any obligation to update or revise publicly forward-looking statements. You should, therefore, not rely on these forward-looking statements as representing the views of the Company as of any date subsequent to the date of this communication.
