## Item 7.01 Regulation FD Disclosure.
On April 20, 2026, FibroBiologics, Inc. (the "Company") issued a press release announcing formal confirmation from The Nasdaq Stock Market LLC ("Nasdaq") that the Company has evidenced compliance with all applicable requirements for continued listing on The Nasdaq Capital Market and, accordingly, the previously disclosed listing matter has been closed. A copy of the press release is furnished as Exhibit 99.1 hereto and is incorporated herein by reference.

The information set forth in this Item 7.01 and contained in the press release furnished as Exhibit 99.1 hereto shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and is not incorporated by reference into any of the Company's filings under the Securities Act or the Exchange Act, whether made before or after the date hereof, except as shall be expressly set forth by specific reference in any such filing.

## Item 8.01 Other Events.
On April 17, 2026, the Company received formal notice from Nasdaq that the Company has demonstrated compliance with the bid price requirement under Nasdaq Listing Rule 5550(a)(2) (the "Bid Price Rule") and all other applicable criteria for continued listing on The Nasdaq Capital Market. Accordingly, the previously disclosed listing matter has been closed.

The Company was also informed that it will remain subject to a Mandatory Panel Monitor for a period of one year from April 17, 2026. If within that one-year monitoring period the Company fails to maintain compliance with the Bid Price Rule, the Company will not be afforded a cure period to regain compliance with the Bid Price Rule. Instead, Staff will issue a delist determination, at which time the Company may request a new hearing before a Nasdaq Hearings Panel. Such request would stay any further delisting action by Nasdaq at least pending the conclusion of the hearing process.

Previously, on March 9, 2026, the Company received notice from Nasdaq that the Company had demonstrated compliance with the stockholders' equity requirement under Nasdaq Listing Rule 5550(b)(1) (the "Equity Rule") in lieu of compliance with the alternative market value of listed securities requirement set forth in Nasdaq Listing Rule 5550(b)(2). The compliance determination also noted that the Company remained subject to a Mandatory Panel Monitor with respect to the Equity Rule for a period of one year from March 9, 2026. If within that one-year monitoring period the Company fails to satisfy the Equity Rule, the Company will not be permitted to provide the Nasdaq Listing Qualifications Staff with a compliance plan nor would the Staff be permitted to grant additional time to the Company to regain compliance. Instead, the Staff will issue a delist determination, at which time the Company may request a new hearing before a Nasdaq Hearings Panel. Such request would stay any delisting action by Nasdaq at least pending the conclusion of the hearing process.
