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

On July 10, 2024, Sensei Biotherapeutics, Inc. (the “Company”) received a letter from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that the listing of its common stock was not in compliance with Nasdaq Listing Rule 5450(a)(1) for continued listing on the Nasdaq Global Market, as the minimum bid price of the Company’s common stock was less than $1.00 per share for the previous 30 consecutive business days. Under Nasdaq Listing Rule 5810(c)(3)(A), the Company has a period of 180 calendar days, or until January 6, 2025, to regain compliance with the rule referred to in this paragraph. To regain compliance, during this 180-day compliance period, the Company’s minimum bid price of listed securities must close at $1.00 per share or more for a minimum of 10 consecutive business days. The notice has no present impact on the listing of the Company’s securities on the Nasdaq Global Market.

If the Company does not regain compliance with the Nasdaq Listing Rules prior to the expiration of the 180-day compliance period, the Company may be eligible for additional time to regain compliance pursuant to Nasdaq Listing Rule 5810(c)(3)(A)(ii) by transferring to the Nasdaq Capital Market. To qualify, the Company would need to submit a Transfer Application and a $5,000 application fee. In addition, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, except the minimum bid price requirement. In addition, the Company would need to provide written notice to Nasdaq of its intention to cure the minimum bid price deficiency during the second compliance period by effecting a reverse stock split, if necessary. As part of its review process, the Nasdaq staff will determine whether it believes the Company will be able to cure this deficiency. Should the Nasdaq staff conclude that the Company will not be able to cure the deficiency, or should the Company determine not to submit a Transfer Application or make the required representation, Nasdaq will provide notice that the Company’s shares of common stock will be subject to delisting.

If the Company does not regain compliance within the allotted compliance period(s), including any extensions that may be granted by Nasdaq, Nasdaq will provide notice that the Company’s shares of common stock will be subject to delisting. At such time, the Company may appeal the delisting determination to a Hearings Panel.

The Company intends to actively monitor its minimum bid price of listed securities and, as appropriate, will consider available options to resolve the deficiencies and regain compliance with the Nasdaq Listing Rules, including applying to transfer to the Nasdaq Capital Market or effecting a reverse stock split.

There can be no assurance that the Company will be successful in maintaining the listing of its common stock on the Nasdaq Global Market, or, if transferred, on the Nasdaq Capital Market.
