Yorkville agreed to advance to FibroBiologics the first $15 million available under the SEPA in three equal tranches to be evidenced by convertible promissory notes. The first tranche in the amount of $5 million was funded upon entry into the SEPA and the second tranche of $5 million was funded after the filing of a registration statement covering the resale of the shares issuable to Yorkville under the promissory notes. The third tranche of $5 million was funded following the effectiveness of the registration statement and receipt of shareholder approval in satisfaction of certain Nasdaq rules. FibroBiologics can sell an additional $10 million of its common stock to Yorkville, subject to Yorkville’s consent and other conditions, while the convertible promissory notes remain outstanding.

The net proceeds of the financing are expected to be used for general corporate purposes, including funding for research and development programs and supporting the upcoming Phase 1/2 diabetic foot ulcer clinical trial expected to begin in the second half of 2025.
