Item 3.01Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On August 13, 2026, SES AI Corporation (the “Company”) received notice from the New York Stock Exchange (the “NYSE”) that the NYSE has determined to (i) commence proceedings to delist the Company’s public warrants (the “Warrants”) and (ii) immediately suspend trading in the Warrants due to “abnormally low selling price” levels, pursuant to Section 802.01D of the NYSE Listed Company Manual. Each Warrant is presently exercisable for one share of the Company’s Class A common stock at an exercise price per share of $11.50, ticker symbol “SES WS.” To effect the delisting, the NYSE will apply to the Securities and Exchange Commission (the “SEC”) to delist the Warrants upon completion of all applicable procedures.

Trading in the Company’s Class A common stock will continue on the NYSE under the ticker symbol “SES”, subject to the Company’s continued compliance with the NYSE’s other continued listing requirements, and is unaffected by this action.

SIGNATURE

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
