Rhea-AI Filing Summary

FibroBiologics, Inc. reported a financing transaction involving a registered direct offering and a concurrent private placement. The company agreed to sell 4,477,614 shares of common stock at $0.335 per share, for expected gross proceeds of about $1.5 million before fees. In the private placement, investors will also receive warrants to purchase up to 4,477,614 additional shares at an exercise price of $0.335 per share, which will become exercisable only if stockholders approve the issuance of the warrant shares.

If the investor warrants are later exercised for cash in full, FibroBiologics would receive about an additional $1.5 million. The company plans to use net proceeds from this financing for working capital and general corporate purposes. H.C. Wainwright & Co. will receive cash fees tied to the purchase price and non-accountable expenses, plus placement agent warrants to buy up to 313,433 shares at $0.4188 per share. The company agreed to a 30-day restriction on issuing additional equity and a one-year restriction on entering Variable Rate Transactions, subject to limited exceptions.

Insights

FibroBiologics adds modest equity capital with attached warrants, creating some dilution and future overhang.

FibroBiologics is raising approximately $1.5 million in gross proceeds through a registered direct sale of 4,477,614 common shares at $0.335 per share, paired with an equal number of investor warrants at the same exercise price. This structure brings in near-term cash while linking potential additional capital to later warrant exercises, which depend on shareholder approval of the warrant share issuance.

If all investor warrants are exercised for cash, the company would receive roughly another $1.5 million, and placement agent warrants cover up to 313,433 shares at $0.4188 per share. A 4.99% beneficial ownership cap limits how much of the company any warrant holder can control immediately after exercise. Near term, the 30-day prohibition on new equity deals and the one-year ban on Variable Rate Transactions, each with exceptions, frame how FibroBiologics can structure additional financings following the expected closing on November 25, 2025.

Item 1.01 Entry into a Material Definitive Agreement.

On November 24, 2025, FibroBiologics, Inc. (the “Company”) entered into a securities purchase agreement (the “Purchase Agreement”) with certain institutional investors (the “Purchasers”), pursuant to which (i) the Company agreed to issue and sell to the Purchasers, in a registered direct offering (the “Registered Direct Offering”), 4,477,614 shares (the “Shares”) of the Company’s common stock, $0.00001 par value per share (the “Common Stock”). The price of each Share in the Registered Direct Offering is $0.335 (the “Offering Price”).

Additionally, pursuant to the Purchase Agreement, the Company will issue and sell to the Purchasers, in a concurrent private placement, warrants to purchase one share of its Common Stock for each Share of Common Stock purchased in the Registered Direct Offering for an aggregate of 4,477,614 shares of Common Stock (the “Warrants”). The exercisability of the Warrants is subject to stockholder approval as described below. The exercise price of the Warrants is $0.335 per share.

The gross proceeds to the Company from the offerings are expected to be approximately $1.5 million, before deducting placement agent fees and offering expenses payable by the Company. In addition, if the holders of the unregistered Warrants exercise such warrants in full for cash following stockholder approval, the Company would receive additional gross proceeds of approximately $1.5 million. However, the Company cannot predict when or if the Warrants will be exercised for cash or exercised at all. It is possible that the Warrants may be exercised on a cashless (net) basis as described below or may expire and never be exercised.

The Registered Direct Offering and concurrent private placement are expected to close on or about November 25, 2025, subject to the satisfaction of customary closing conditions. The Company currently plans to use the net proceeds from the Registered Direct Offering and concurrent private placement for working capital and general corporate purposes.

Pursuant to the terms of the Purchase Agreement, the Company has agreed, subject to limited exceptions, for a period ending 30 days following the closing of the Registered Direct Offering, not to issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock equivalents. The Company has also agreed not to enter into a Variable Rate Transaction (as defined in the Purchase Agreement) for one year after the completion of the Registered Direct Offering, subject to limited exceptions.

H.C. Wainwright & Co., LLC is acting as the exclusive placement agent (the “Placement Agent”) on a “reasonable best efforts” basis, in connection with the Registered Direct Offering and concurrent private placement pursuant to that certain engagement letter, dated November 10, 2025 (the “Engagement Letter”), by and between the Company and the Placement Agent. Pursuant to the Engagement Letter, the Placement Agent will receive (i) a cash fee of 7.0% of the aggregate purchase price paid by the Purchasers in the Registered Direct Offering and (ii) a management fee of 1.0% of the aggregate purchase price paid by the Purchasers in the Registered Direct Offering. In addition, the Company has agreed to pay the Placement Agent non-accountable expenses of $25,000 and clearing fees of $15,950. Additionally, the Company will issue to the Placement Agent (or its designees) warrants to purchase 7.0% of the number of Shares of Common Stock sold in this the Registered Direct Offering (or warrants to purchase up to 313,433 shares of Common Stock), at an exercise price of $0.4188 per share (the “Placement Agent Warrants”). The Placement Agent Warrants will expire five years from the commencement of the sales in this offering.

Except as provided above, the Placement Agent Warrants will have substantially the same terms as the Warrants issued in the private placement being conducted concurrently with the Registered Direct Offering.

The Purchase Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, including for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), other obligations of the parties, and termination provisions. The representations, warranties and covenants contained in the Purchase Agreement were made only for the purposes of such agreement and as of the specific dates, were solely for the benefit of the parties to such agreement and may be subject to limitations agreed upon by the contracting parties.

The Registered Direct Offering was made pursuant to the Company’s effective registration statement on Form S-3 (Registration Statement No. 333-284663) that was originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 3, 2025, and became effective on February 10, 2025, and the base prospectus contained therein and a prospectus supplement thereto that will be filed by the Company with the SEC.

Terms of Warrants

The Warrants have an exercise price of $0.335 per share of Common Stock. The Warrants will not be exercisable until, and are subject to, approval by the Company’s stockholders of the issuance of the Warrant Shares and will expire five years following the date of the stockholder approval, if it is obtained. The Company intends to submit the issuance of the Warrant Shares upon exercise of the Warrants for approval of its shareholders, but there can be no assurance that such approval will be obtained. A holder of the Warrants will not have the right to exercise any portion of its Warrants if such holder, together with its affiliates, would beneficially own in excess of 4.99% of the number of Common Stock outstanding immediately after giving effect to such exercise. The Company has agreed to file


a registration statement with the SEC to register the resale of the Warrant Shares as soon as practicable (and in any event within 45 days after the date of the Purchase Agreement) and to use commercially reasonable efforts to cause such registration statement to become effective within 60 days (90 days in the event the SEC elects to review the registration statement) following the date of the closing of the Registered Direct Offering and concurrent private placement (the "Closing"). If at the time of exercise of the Warrants there is no effective registration statement registering the Warrant Shares for resale or the prospectus contained therein is not available for the resale of the Warrant Shares by the holder of the Warrants, then the Warrants may also be exercised, in whole or in part, by cashless (net) exercise. The exercise price of the Warrants is subject to customary adjustment for stock splits, stock dividends, stock combinations, and similar capital transactions or such other event as further described in the Warrants.
