FibroBiologics Closes Third $5 Million Tranche of $25 Million Financing

HOUSTON, June 16, 2025 (GLOBE NEWSWIRE) -- FibroBiologics, Inc. (Nasdaq: FBLG) (“FibroBiologics”), a clinical-stage biotechnology company with 275+ 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 it has closed the third $5 million tranche of the previously announced Standby Equity Purchase Agreement (the “SEPA”) with YA II PN, Ltd. (“Yorkville”), an investment fund managed by Yorkville Advisors Global, LP. The agreement allows FibroBiologics, subject to customary conditions, to sell up to $25 million in the aggregate of its common stock to Yorkville over the course of two years.   

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.
