Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.
On July 1, 2025, FibroBiologics, Inc. (the "Company") received a notification letter from the Listing Qualifications Staff (the "Staff") of The Nasdaq Stock Market LLC ("Nasdaq") notifying the Company that the closing bid price of the Company's shares of common stock was below the minimum closing bid price of $1.00 per share during the last 30 consecutive trading days (the "Notice"), as required for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2).
The Notice has no immediate impact on the listing of the Company's common stock, which will continue to be listed and traded on The Nasdaq Capital Market subject to the Company's continued compliance with the other listing requirements.
In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided an initial period of 180 calendar days, or until December 29, 2025, to regain compliance with this requirement. To regain compliance, the closing bid price of the Company's common stock must be $1.00 per share or more for a minimum of 10 consecutive business days at any time before December 29, 2025. If the Company does not regain compliance with Rule 5550(a)(2) by December 29, 2025, the Company may be eligible for an additional 180 calendar day compliance period. To qualify, the Company 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, except the bid price requirement, and will need to provide written notice to Nasdaq of its intention to cure the deficiency during the second compliance period. If it appears to the Staff that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible, Nasdaq will notify the Company that its securities will be subject to delisting. In the event of such notification, the Company may appeal the Staff's determination to delist its securities, but there can be no assurance the Staff will grant the Company's request for continued listing.
The Company will continue to monitor the closing bid price of its common stock and may, as appropriate, consider available options to regain compliance.
This Current Report on Form 8-K is filed to satisfy the obligation under Nasdaq Listing Rule 5810(b) and Item 3.01(a) of Form 8-K that the Company publicly disclose the receipt of the Notice within four (4) business days after the date of the Notice.
