FibroBiologics Announces Closing of $1.5 Million Registered Direct Offering Priced At-the-Market Under Nasdaq Rules

HOUSTON, Nov. 25, 2025 (GLOBE NEWSWIRE) -- FibroBiologics, Inc. (NASDAQ:FBLG) ("FibroBiologics" or the "Company"), a clinical-stage biotechnology company with 270+ patents issued and pending with a focus on the development of therapeutics and potential cures for chronic diseases using fibroblasts and fibroblast-derived materials, today announced the closing of its previously announced registered direct offering priced at-the-market under Nasdaq rules of an aggregate of 4,477,614 shares of its common stock at an offering price of $0.335 per share of common stock. Additionally, in a concurrent private placement, the Company issued and sold unregistered warrants to purchase up to an aggregate of 4,477,614 shares of common stock at an exercise price of $0.335 per share. The unregistered warrants will be exercisable beginning on the effective date of, and subject to, approval by the Company's stockholders of the issuance of the shares of common stock upon exercise of the unregistered warrants (the "Stockholder Approval") and will expire five years following the date of Stockholder Approval.

H.C. Wainwright & Co. acted as the exclusive placement agent for the offering.

The aggregate gross proceeds to the Company from the offering were approximately $1.5 million, before deducting the placement agent's fees and other offering expenses payable by the Company. The potential additional gross proceeds to the Company from the unregistered warrants, if fully exercised on a cash basis, will be approximately $1.5 million. No assurance can be given that the Stockholder Approval will be achieved or that any of the unregistered warrants will be exercised. FibroBiologics intends to use the net proceeds from the offering for working capital and general corporate purposes.

The shares of common stock offered in the registered direct offering (but not the unregistered warrants issued in the concurrent private placement and the shares issuable upon exercise of such unregistered warrants) described above were offered pursuant to a "shelf" registration statement on Form S-3 (File No. 333-284663) initially filed with the Securities and Exchange Commission (the "SEC") on February 3, 2025 and which became effective on February 10, 2025. The offering of the shares of common stock in the registered direct offering were made only by means of a prospectus, including a prospectus supplement, forming a part of the effective registration statement. A final prospectus supplement and accompanying prospectus relating to the registered direct offering were filed with the SEC. Electronic copies of the final prospectus supplement and accompanying prospectus may be obtained on the SEC's website at http://www.sec.gov or by contacting H.C. Wainwright & Co., LLC at 430 Park Avenue, 3rd Floor, New York, New York 10022, by phone at (212) 856-5711 or e-mail at [email protected].

The unregistered warrants issued in the concurrent private placement and the shares issuable upon exercise of such warrants were offered in a private placement under Section 4(a)(2) of the Securities Act of 1933, as amended (the "Act"), and/or Regulation D promulgated thereunder, have not been registered under the Act or applicable state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy any of the securities described herein, nor shall there be any sale of these securities in any state or other jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or other jurisdiction.
