Convertible Notes Payable

Note 4: Convertible Notes Payable

 

On March 8, 2024, the Company issued an aggregate principal amount of $6,000,000 of its 8.0% Senior Secured Convertible Promissory Notes (the “Convertible Notes”) in a private placement. The purchasers of the Convertible Notes included immediate family members and family trusts related to Mark Emalfarb, our President and Chief Executive Officer and a member of our Board of Directors, including The Francisco Trust, an existing holder of more than 5% of the Company’s outstanding common stock (collectively, the “Purchasers”). The net proceeds from the sale of Convertible Notes, after deducting offering expenses, were $5,824,326. The Company intends to use the net proceeds from the offering of the Convertible Notes for working capital and general corporate purposes.

 

The Convertible Notes are senior, secured obligations of Dyadic and its affiliates, and interest is payable quarterly in cash on the principal amount equal to 8% per annum. The Convertible Notes, as amended, will mature on December 31, 2027 (the “Maturity Date”), unless earlier converted, repurchased, or redeemed in accordance with the terms of the Convertible Notes. The Convertible Notes can be converted into shares of common stock, at the option of the holders of the Convertible Notes (the “Noteholders”) at any time prior to the Maturity Date.

 

The Convertible Notes are secured by a first priority lien on substantially all assets of the Company and Dyadic International (USA), Inc.

 

The Convertible Notes are accounted for in accordance with ASC 470-20, Debt with Conversion and Other Options and ASC 815-15, Derivatives and Hedging. Under ASC 815, contracts that are both indexed to its own stock and classified in stockholders’ equity in its statement of financial position are not considered to be derivative instruments. Based on the Company’s analysis, it is determined that the Convertible Notes contain embedded features that are indexed to the Company’s own stock and are classified in stockholders’ equity in the Company’s statement of financial position, but do not meet the requirements for bifurcation and recognition as derivatives, and therefore, do not need to be accounted for separately. Accordingly, the proceeds received from the issuance of the Convertible Notes were recorded as a single liability in accordance with ASC 470 on the Company’s consolidated balance sheets.

 

The Company incurred $175,674 of debt issuance costs associated with the Convertible Notes, which were recorded as a reduction of the Convertible Notes on the consolidated balance sheets. The debt issuance costs are being amortized and recognized as additional interest expense over the expected life of the Convertible Notes using the effective interest method. We determined that the expected life of the debt is equal to the three-year term of the Convertible Notes.

 

 

On October 4, 2024, the Company entered into an amendment (the “Amendment”) to the Convertible Notes. Under the Amendment, (i) the conversion price at which the Convertible Notes are convertible into shares of the Company’s common stock was set at $1.40 per share, and (ii) the Redemption Date (as defined in the Amendment) was extended to any of the 26, 29 and 32-month anniversaries of the original issue date of the Convertible Notes.

 

During the year ended December 31, 2024, $910,000 of the Convertible Notes were converted into 556,623 shares of the Company’s common stock.

 

On May 1, 2025, the Company amended the Convertible Notes to extend the Redemption Date (as defined in the Convertible Notes) to December 1, 2026.

 

On September 15, 2025, the Company amended the security agreement to reflect updates to the Secured Parties (as defined in the Security Agreement) thereunder, including the addition of a trust for the benefit of the Company’s Chief Executive Officer, Mark Emalfarb, as a result of his purchase and assignment to him of one of the Notes from an existing note holder in a principal amount of $1,000,000.

 

On December 23, 2025, the Company entered into an additional amendment to the Convertible Notes, pursuant to which (i) the Maturity Date (as defined in the Convertible Notes) was extended from March 8, 2027 to December 31, 2027, (ii) the conversion price at which the Convertible Notes are convertible into shares of the Company’s common stock was set at $1.05 per share of common stock, and (iii) except in the case of an Event of Default (as defined in the Convertible Notes), the holders no longer have the right to elect to have the Company redeem all, or any part, of the principal amount then remaining under the Convertible Notes.

 

The Company assessed each of the Amendments for a debt extinguishment or modification in accordance with ASC 470-50. As both the changes in the present value of future cash flows of the modified Convertible Notes to that of the original Convertible Notes (including callable features) and the change in fair value of the embedded conversion option to that of the carrying value of the Convertible Notes immediately before modification resulted in a less than 10% change, none of the Amendments were deemed substantial and they are regarded as note modifications. The Company did not incur any gain or loss relating to the modifications and any incremental costs, including legal fees, related to the Amendments were expensed.

 

For the three months ended March 31, 2026 and 2025, $101,800 and $107,173 of interest were paid, and debt issuance costs of $7,381 and $11,762 were amortized and recorded in interest expenses in the consolidated statements of operations, respectively.

 

As of March 31, 2026, accrued interest on the Convertible Notes totaled $41,800 for related parties and $60,000 for other third parties. As of March 31, 2026 and 2025, accumulated amortized debt issuance costs was $116,645 and $48,138, respectively.

Emalfarb Trust dated October 1, 1987, as amended and restated on June 28, 2019 (the “MAE Trust”), purchased and was assigned $1,000,000 of the Convertible Notes from an existing note holder. Mr. Mark A. Emalfarb, our Chief Executive Officer, is the sole beneficiary and serves as sole trustee of the MAE Trust and has sole voting and dispositive power over the shares of common stock held by the MAE Trust. As of March 31, 2026, the amount of accrued interest for the MAE Trust was $20,000.
(2) Mr. Thomas Emalfarb, nephew of Mr. Mark A. Emalfarb, our Chief Executive Officer, is the trustee of the Francisco Trust.

(3) Mr. Mark A. Emalfarb, our Chief Executive Officer, is the trustee of the Irrevocable Trust and the brother of Mr. Bradley S. Emalfarb, who is the sole beneficiary of the Irrevocable Trust. Mr. Bradley S.

(4) Messrs. Thomas Emalfarb, Scott Emalfarb and Michael Emalfarb, nephews of Mr. Mark A.

The Company was in compliance with its covenants with respect to the Convertible Notes as of March 31, 2026.
