Rhea-AI Filing Summary

FibroBiologics, Inc. (FBLG) closed a private placement with Peak One Opportunity Fund, L.P. on October 8, 2026, issuing a $1.2 million principal convertible debenture for a $1.02 million purchase price, reflecting a 15% original issue discount, and 125,000 restricted Commitment Shares to Peak One and its designee.

The debenture matures October 8, 2027, bears 0% annual interest, and is convertible at $0.78 per share only after an Event of Default. Payments are $1,080,000 on April 8, 2027, $60,000 on July 8, 2027, and $60,000 or the remaining balance, if higher, at maturity. Following default, the holder may raise interest to the lesser of 18% or the legal maximum and accelerate the full indebtedness in an amount equal to 120% of outstanding principal and accrued and unpaid interest. Issuances under the SPA and debenture are capped at 1,671,094 shares absent stockholder approval, with a 4.99% beneficial-ownership limit. At the holder's sole discretion, if aggregate cash proceeds exceed $1.5 million, the company agreed to use 50% of those proceeds to repay the debenture and, subject to limited exceptions, not enter a Variable Rate Transaction while it remains outstanding.

Filing Explained

For the debenture issued at closing, FibroBiologics may redeem it at 100% of principal so long as no Event of Default has occurred and is continuing; redemption is a company option, not a required payment.

original issue discount financial
"representing an original issue discount of fifteen percent"
Original issue discount (OID) is the difference between a debt security’s face value and the lower price at which it is first sold, treated as additional interest that accrues over the life of the instrument. For investors it matters because OID raises the effective yield and changes taxable income and the holding’s cost basis over time — think of buying a $100 voucher for $90 and recognizing the $10 gain as earned interest as the voucher approaches maturity.
Event of Default financial
"only convertible following an Event of Default"
An event of default is a specific breach of a loan or bond agreement—such as missed payments or breaking agreed rules—that gives lenders the legal right to act, for example by demanding immediate repayment, seizing collateral, or accelerating other obligations. For investors, it’s a red flag because it can sharply reduce a company’s ability to operate or raise money, like a car lender repossessing a vehicle after missed payments, and often leads to falling share or bond prices.
Exchange Cap regulatory
"the “Exchange Cap”"
Variable Rate Transaction financial
"not to enter into a Variable Rate Transaction"

Item 1.01 Entry into a Material Definitive Agreement.

On October 7, 2026, FibroBiologics, Inc. (the “Company”) entered into a securities purchase agreement (the “SPA”) with Peak One Opportunity Fund, L.P. (“Peak One”), pursuant to which the Company agreed to issue to Peak One, in a private placement offering (the “Offering”) upon the satisfaction of certain conditions specified in the SPA, a convertible debenture in the principal amount of $1,200,000 (the “Debenture”) and 125,000 restricted shares (the “Commitment Shares”) of the Company’s common stock, par value $0.00001 per share (the “common stock”).

The Offering closed on October 8, 2026, and the Company issued the Debenture to Peak One and the Commitment Shares to Peak One and Peak One’s designee as described in the SPA. The Debenture was sold to Peak One for a purchase price of $1,020,000, representing an original issue discount of fifteen percent (15%). In connection with the offering, the Company paid $20,000 as a non-accountable fee to Peak One to cover its accounting fees, legal fees and other transactional costs incurred in connection with the transactions contemplated by the SPA and issued the Commitment Shares to Peak One and its designee as described in the SPA.

The Debenture matures on October 8, 2027, accrues interest on the outstanding principal balance at an annual rate equal to 0%, and is only convertible following an Event of Default at a fixed conversion price equal to $0.78 per share. Upon an Event of Default, the holder of the Debenture can increase the interest rate applicable to the Debenture to the lesser of eighteen percent (18%) per annum and the maximum interest rate allowable under applicable law and accelerate the full indebtedness under the Debenture, in an amount equal to one hundred twenty percent (120%) of the outstanding principal amount and accrued and unpaid interest.

Pursuant to the terms of the Debenture, (i) the Company must make interim payments of $1,080,000 on April 8, 2027, $60,000 on July 8, 2027, and $60,000 (or the remaining balance, if higher) at maturity; (ii) at the sole discretion of the holder of the Debenture, the Company agreed to use 50% of cash proceeds it receives of more than $1,500,000, in the aggregate, from any source or series of related or unrelated sources, including but not limited to the issuance of equity or debt, the conversion of outstanding warrants of the Company or subsidiary of the Company, the issuance of securities pursuant to an Equity Line of Credit (as defined in this Debenture) or ATM Offering (as defined in the Debenture), or the sale of assets by the Company or subsidiary of the Company, to repay outstanding amounts owed under the Debenture; and (iii) the Company agreed, subject to limited exceptions, not to enter into a Variable Rate Transaction (as defined in the SPA) while the Debenture remains outstanding.

The Company can redeem the Debenture at 100% of the principal amount at any time so long as no Event of Default shall have occurred and be continuing.

Under the applicable rules of The Nasdaq Stock Market LLC and pursuant to the SPA and the Debenture, in no event may the Company issue or sell shares of common stock in excess of 1,671,094 shares (the “Exchange Cap”) pursuant to the SPA and the Debenture, unless the Company obtains stockholder approval to issue shares of common stock in excess of the Exchange Cap.

In addition, the Company may not issue or sell any shares of common stock under the SPA or under the Debenture, which, when aggregated with all other shares of common stock then beneficially owned by the holder and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Regulation 13D-G thereunder) would result in the holder and its affiliates beneficially owning more than 4.99% of the then-outstanding shares of common stock.

The SPA contains customary representations, warranties and agreements by the Company and Peak One, and customary conditions to closing. The representations, warranties and agreements contained in the SPA were made only for purposes of the SPA and as of a specific date, were solely for the benefit of the parties to the SPA, and may be subject to limitations agreed upon by the contracting parties.

 

The foregoing descriptions of the SPA and the Debenture do not purport to be complete and are qualified in their entirety by reference to the full text of the SPA and Debenture attached hereto as Exhibit 10.1 and Exhibit 10.2, respectively, which are incorporated herein by reference.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The disclosure set forth above in Item 1.01 of this Current Report on Form 8-K relating to the Offering, the issuance of shares of common stock pursuant to the SPA and the Debenture, including the Commitment Shares, and to the issuance of the Debenture is incorporated by reference herein in its entirety. The offer and sale of shares of common stock and the issuance of the Debenture pursuant to the SPA was and will be made in reliance upon the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as


amended, and Rule 506(b) of Regulation D promulgated thereunder.
