EXPLANATORY NOTE

Warrant Delisting

Valens Semiconductor Ltd. (the “Company”) was notified by the New York Stock Exchange (“NYSE”) that the NYSE staff have determined to commence proceedings to delist the Company’s warrants to purchase one-half of one ordinary share of the Company (the “Warrants”), under the ticker VLNW, from NYSE on July 24, 2026.

Trading in the Warrants on the NYSE will be suspended as of July 24, 2026. The Warrants remain outstanding until their expiration date on September 29, 2026 and until such time each may be exercised at an exercise price of $11.50 per one ordinary share.

Trading in the Company’s ordinary shares under the ticker VLN will continue on the NYSE and not be impacted.
