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

On June 22, 2022, Sigilon Therapeutics, Inc. (the “Company”) received written notice (the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) notifying the Company that, based on the closing bid price of the Company’s common stock, par value $0.001 per share (the “Common Stock”), for the last 30 consecutive business days, the Company no longer complies with the minimum bid price requirement for continued listing on The Nasdaq Global Select Market. Nasdaq Listing Rule 5450(a) requires listed securities to maintain a minimum bid price of $1.00 per share (the “Minimum Bid Price Requirement”), and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the Minimum Bid Price Requirement exists if the deficiency continues for a period of 30 consecutive business days.

The Notice has no immediate effect on the listing of the Company’s Common Stock on The Nasdaq Global Select Market. Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided an initial compliance period of 180 calendar days from receipt of the Notice, or until December 19, 2022, to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price of the Company’s Common Stock must be at least $1.00 per share for a minimum of 10 consecutive business days prior to December 19, 2022, unless Nasdaq exercises its discretion to extend this period pursuant to Nasdaq Listing Rule 5810(c)(3)(H). There can be no assurance the Company will be able to regain compliance.

If the Company does not regain compliance by December 19, 2022, the Company may be eligible for an additional 180 calendar day compliance period. To qualify, the Company must submit an application to transfer to The Nasdaq Capital Market and will 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, with the exception of the requirement that listed securities maintain a Minimum Bid Price. The Company would also need to provide written notice of its intention to cure the deficiency during the second 180 calendar day compliance period, such as by effecting a reverse stock split, if necessary.

If the Company does not regain compliance within the compliance period(s), including any extensions that may be granted by Nasdaq, Nasdaq will provide notice that the Company’s Common Stock will be subject to delisting. The Company can seek review of the delisting determination by a hearing panel and also appeal a decision of such hearing panel to the Nasdaq Listing and Hearing Review Council. There can be no assurance that, if the Company decides to appeal the delisting determination, such appeal would be successful.

The Company intends to monitor the closing bid price of the Company’s Common Stock and consider its available options to resolve the noncompliance with the Minimum Bid Price Requirement, including, subject to approval of the Company’s Board of Directors and stockholders, implementing a reverse stock split. There can be no assurance that a reverse stock split would be approved or would result in a sustained higher stock price that would allow the Company to meet the Minimum Bid Price Requirement.


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 hereunto duly authorized.
