DYADIC INTERNATIONAL INC 8-K

What Happened
Dyadic International, Inc. (DYAI) filed an 8-K on December 29, 2025 disclosing that on December 23, 2025 it entered an amendment to its Form of Senior Secured Convertible Promissory Note (the “Convertible Notes”). The amendment extends the notes’ maturity from March 8, 2027 to December 31, 2027, sets the conversion price at $1.05 per share of common stock, and removes holders’ general right to elect redemption of principal except in the case of an Event of Default. The full amendment is attached as Exhibit 4.1 to the filing.

Key Details

• Amendment date: December 23, 2025; 8-K filed December 29, 2025.
• Maturity extended from March 8, 2027 to December 31, 2027.
• New conversion price: $1.05 per share of common stock.
• Holders no longer have the right to elect redemption of outstanding principal except upon an Event of Default.

Why It Matters
This amendment changes the timing and mechanics of Dyadic’s outstanding convertible debt. Extending the maturity delays when the company must repay or otherwise settle the principal, and the established $1.05 conversion price determines how many shares would be issued if noteholders convert (affecting potential dilution). Removing the routine redemption election limits noteholders’ ability to demand cash repayment prior to maturity (except on default), which can reduce near-term cash outflow risk for the company. Investors should note these concrete changes to Dyadic’s capital structure and monitor future disclosures for any further modifications or conversions.
