Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. As previously disclosed, on November 1, 2024, Adaptimmune Therapeutics plc (the "Company") received a notice from The Nasdaq Stock Market ("Nasdaq") that the Company was not in compliance with Nasdaq's Listing Rule 5450(a)(1), because the minimum bid price of the Company's American Depositary Shares ("ADSs") had been below $1.00 per share for 30 consecutive business days.

Accordingly, the Company intends to timely request a hearing and therefore expects to be scheduled for a hearing before the Panel, and any delisting action by Nasdaq will be stayed pending the issuance of the Panel's decision following the hearing and the expiration of any extension period that may be granted by the Panel. At the hearing, the Company will present its plan to evidence compliance with the Rules and req
