EXPLANATORY NOTE

On April 23, 2025, the NYSE provided written notice to Wallbox N.V. (the “Company”) and thereafter publicly announced that NYSE Regulation has determined to commence proceedings to delist the Company’s warrants trading under the ticker symbol “WBX.WS” (the “Warrants”) as the Warrants are no longer suitable for listing based on “abnormally low selling price,” pursuant to Section 802.01D of the NYSE Listed Company Manual. Trading in these Warrants on NYSE will be suspended immediately. To effect the delisting, the NYSE will apply to the Securities and Exchange Commission to delist the Warrants pending completion of applicable procedures. Trading in the Company’s Class A ordinary shares, ticker symbol “WBX,” will continue on the NYSE and is unaffected by this action.
