LANVIN GROUP 2025 FULL - YEAR RESULTS April 30, 2026

2 Forward-Looking Statements This presentation, including the sections “2026 GUIDANCE”, “BRAND-LEVEL PERFORMANCE” and “APPENDIX”, contain “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook,” “project” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunity. These statements are based on various assumptions, whether or not identified in this presentation, and on the current expectations of the respective management of Lanvin Group and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and must not be relied on by an investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Lanvin Group. Potential risks and uncertainties that could cause the actual results to differ materially from those expressed or implied by forward-looking statements include, but are not limited to, changes adversely affecting the business in which Lanvin Group is engaged; Lanvin Group’s projected financial information, anticipated growth rate, profitability and market opportunity may not be an indication of its actual results or future results; management of growth; the impact of health epidemics, pandemics and similar outbreaks, including the COVID-19 pandemic on Lanvin Group’s business; Lanvin Group’s ability to safeguard the value, recognition and reputation of its brands and to identify and respond to new and changing customer preferences; the ability and desire of consumers to shop; Lanvin Group’s ability to successfully implement its business strategies and plans; Lanvin Group’s ability to effectively manage its advertising and marketing expenses and achieve desired impact; its ability to accurately forecast consumer demand; high levels of competition in the personal luxury products market; disruptions to Lanvin Group’s distribution facilities or its distribution partners; Lanvin Group’s ability to negotiate, maintain or renew its license agreements; Lanvin Group’s ability to protect its intellectual property rights; Lanvin Group’s ability to attract and retain qualified employees and preserve craftsmanship skills; Lanvin Group’s ability to develop and maintain effective internal controls; general economic conditions; the result of future financing efforts; and those factors discussed in the reports filed by Lanvin Group from time to time with the SEC. If any of these risks materialize or Lanvin Group’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that Lanvin Group presently does not know, or that Lanvin Group currently believes are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Lanvin Group’s expectations, plans, or forecasts of future events and views as of the date of this presentation. Lanvin Group anticipates that subsequent events and developments will cause Lanvin Group’s assessments to change. However, while Lanvin Group may elect to update these forward-looking statements at some point in the future, Lanvin Group specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing Lanvin Group’s assessments of any date subsequent to the date of this presentation. Accordingly, reliance should not be placed upon the forward-looking statements. Use of Non-IFRS Financial Metrics This presentation includes certain non-IFRS financial measures (including on a forward-looking basis) such as contribution profit, contribution profit margin, adjusted earnings before interest and taxes (“Adjusted EBIT”), and adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) and trade working capital. These non-IFRS measures are an addition, and not a substitute for or superior to measures of financial performance prepared in accordance with IFRS and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with IFRS. Reconciliations of non-IFRS measures to their most directly comparable IFRS counterparts are included in the Appendix to this presentation. Lanvin Group believes that these non- IFRS measures of financial results (including on a forward-looking basis) provide useful supplemental information to investors about Lanvin Group. Lanvin Group's management uses forward looking non-IFRS measures to evaluate Lanvin Group's projected financial and operating performance. Lanvin Group believes that the use of these non-IFRS financial measures provides an additional tool for investors to use in evaluating projected operating results and trends in and in comparing Lanvin Group's financial measures with other similar companies, many of which present similar non-IFRS financial measures to investors. However, there are a number of limitations related to the use of these non-IFRS measures and their nearest IFRS equivalents. For example, other companies may calculate non-IFRS measures differently, or may use other measures to calculate their financial performance, and therefore Lanvin Group's non-IFRS measures may not be directly comparable to similarly titled measures of other companies. Lanvin Group does not consider these non-IFRS measures in isolation or as an alternative to financial measures determined in accordance with IFRS. The principal limitation of these non-IFRS financial measures is that they exclude significant expenses, income and tax liabilities that are required by IFRS to be recorded in Lanvin Group's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgements by Lanvin Group about which expense and income are excluded or included in determining these non-IFRS financial measures. In order to compensate for these limitations, Lanvin Group presents non-IFRS financial measures in connection with IFRS results. DISCLAIMER

42 Our management monitors and evaluates operating and financial performance using several non-IFRS financial measures including: contribution profit, contribution profit margin, Adjusted EBIT and Adjusted EBITDA. Our management believes that these non-IFRS financial measures provide useful and relevant information regarding our performance and improve their ability to assess financial performance and financial position. They also provide comparable measures that facilitate management’s ability to identify operational trends, as well as make decisions regarding future spending, resource allocations and other operational decisions. While similar measures are widely used in the industry in which we operate, the financial measures that we use 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. Contribution profit is defined as revenues less the cost of sales and selling and marketing expenses. Contribution profit subtracts the main variable expenses of selling and marketing expenses from gross profit, and our management believes this measure is an important indicator of profitability at the marginal level. Below contribution profit, the main expenses are general administrative expenses and other operating expenses (which include foreign exchange gains or losses and impairment losses). As we continue to improve the management of our portfolio brands, we believe we can achieve greater economy of scale across the different brands by maintaining the fixed expenses at a lower level as a proportion of revenue. We therefore use contribution profit margin as a key indicator of profitability at the group level as well as the portfolio brand level. Contribution profit margin is defined as contribution profit divided by revenues. Adjusted EBIT is defined as profit or loss before income taxes, net finance cost, share based compensation, adjusted for income and costs which are significant in nature and that management considers not reflective of underlying operational activities, mainly including net gains on disposal of long-term assets, negative goodwill from acquisition of Sergio Rossi, gain on debt restructuring and government grants. Adjusted EBITDA is defined as profit or loss before income taxes, net finance cost, exchange gains/(losses), depreciation, amortization, share based compensation and provisions and impairment losses adjusted for income and costs which are significant in nature and that management considers not reflective of underlying operational activities, mainly including net gains on disposal of long-term assets, negative goodwill from acquisition of Sergio Rossi, gain on debt restructuring and government grants. Trade working capital is defined as the sum of inventories as well as trade receivables less trade payables. NON-IFRS FINANCIAL MEASURES AND DEFINITION
