Other Events

On June 24, 2026, the New York Stock Exchange (the “NYSE”) notified Lanvin Group Holdings Limited (the “Company”), and on June 25, 2026 issued a press release that it determined to commence proceedings to delist the Company’s warrants that are listed to trade on the NYSE under the ticker symbol “LANV-WT” (the “Warrants”) due to “abnormally low selling price” of the Warrants pursuant to Section 802.01D of the NYSE Listed Company Manual. Trading in the Warrants on the NYSE will be suspended immediately. To effect the Warrant delisting, the NYSE will apply to the Securities and Exchange Commission to delist the Warrants pending completion of applicable procedures.

It is important to note that this action relates solely to the Warrants and does not affect the listing or trading of the Company's ordinary shares, which will continue to trade on the NYSE under the ticker symbol “LANV.”
