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

On December 6, 2022, Synlogic, Inc. (the “Company”) received a written notice from The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that, based upon 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 Common Stock did not meet the minimum bid price of $1.00 per share required by Nasdaq Listing Rule 5450(a)(1), initiating an automatic 180 calendar-day grace period for the Company to regain compliance.

The notice has no immediate effect on the listing or trading of the Company’s Common Stock, and the Common Stock will continue to trade on the Nasdaq Global Market under the symbol “SYBX.”

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has a period of 180 calendar days from the date of the notification, or until June 5, 2023, to achieve compliance with the minimum bid price requirement. The Company will regain compliance with the minimum bid price requirement if at any time before June 5, 2023, the bid price for the Company’s Common Stock closes at or above $1.00 per share for a minimum of 10 consecutive business days.

If the Company does not regain compliance within the allotted compliance period, including any extensions that may be granted by Nasdaq, Nasdaq will provide notice that the Common Stock will be subject to delisting from the Nasdaq Global Market. At such time, the Company may appeal the delisting determination to a hearings panel.

The Company intends to continue to monitor the bid price levels for the Common Stock and will consider appropriate alternatives to achieve compliance within the initial 180 calendar-day compliance period, including, among other things, a potential reverse stock split. There can be no assurance, however, that the Company will be able to do so.


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.
