3. Convertible Notes Payable – Related Party
On April 16, 2021, the Company and Richard E. Uihlein entered into a debt financing arrangement whereby Mr. Uihlein loaned $10,000,000 to the Company. In consideration for the loan, the Company issued a convertible promissory note (the “April 2021 Note”) in the principal amount of ten million dollars.
The April 2021 Note had an original maturity date of April 16, 2025, is prepayable at the option of the Company in whole or in part at any time and is convertible into the Company’s common stock at a conversion price equal to $5.00 per share at the option of the noteholder. The April 2021 Note bears interest at the rate of two percent (2%) per annum, compounded annually with an effective interest rate of approximately 3%. For the three months ended March 31, 2026 and 2025, approximately $54,000 and $53,000, respectively, of interest expense was accrued and included with the principal in the financial statements.
The April 2021 Note also includes a contingent interest component that requires the Company to pay additional interest at a rate of two and one-half percent (2.5%) per quarter (10% per annum) (the “Additional Interest”) beginning on the date of issuance of this Note and ending on the maturity date, provided however, that such payment is only required if and only if the noteholder elects to convert the entire balance of the April 2021 Note into the Company’s common stock on or prior to maturity. As the contingent event is not based on creditworthiness, such feature is not clearly and closely related to the host instrument and accordingly must be bifurcated and recognized as a derivative liability and a debt discount on the April 2021 Note at its inception. The fair value of the contingent interest derivative liability was $420,000 at note inception (April 16, 2021). The fair value of the contingent interest derivative liability was $1,330,000 and $1,680,000 at March 31, 2026 and December 31, 2025, respectively, and is recognized as a derivative liability in the consolidated balance sheet. The change in the fair value of the derivative liability for the three months ended March 31, 2026 and 2025 of $(350,000) and $89,000 respectively, was charged to other expense for the three months ended March 31, 2026 and 2025. The amortization of the original $420,000 debt discount of $26,000 was recorded as additional interest expense for the three months ended March 31, 2025. The debt discount was fully amortized at December 31, 2025.
On May 14, 2024, Mr. Uihlein, as holder of the April 2021 Note irrevocably elected to convert the entire principal amount of such note, plus accrued and unpaid interest, into shares of common stock of the Company at a price of $5.00 per share, effective as of April 16, 2025, which is the maturity date of the April 2021 Note. In connection with entering into the March 2025 Supplemental Line of Credit (see Note 10), the Company agreed to extend the maturity date of the Convertible Promissory Note dated April 2021 from April 16, 2025 to September 30, 2025. Additionally, in connection with entering into the July 2025 Supplemental Line of Credit (see Note 10), the Company agreed to extend the maturity date of the Convertible Promissory Note dated April 2021 (and the September 2021 and December 2021 Convertible Notes) from September 30, 2025 to September 30, 2026. Finally, in connection with entering into the December 2025 Supplemental Line of Credit (see Note 9), the Company agreed to extend the maturity date of the Convertible Promissory Note dated April 2021 (and the September 2021 and December 2021 Convertible Notes) from September 30, 2026 to June 30, 2027. The April 2021 Note will remain outstanding and accrue interest until maturity, and no shares of common stock will be issued as a result of this election until June 30, 2027.
The September 2021 Note had an original maturity date of September 17, 2025, is prepayable at the option of the Company in whole or in part at any time and is convertible into the Company’s common stock at a conversion price equal to $8.64 per share at the option of the noteholder. The September 2021 Note bears interest at the rate of two percent (2%) per annum, compounded annually with an effective interest rate of approximately 3%. For the three months ended March 31, 2026 and 2025, approximately $54,000 and $53,000, respectively, of interest expense was accrued and included with the principal in the financial statements.
The September 2021 Note also includes a contingent interest
component that requires the Company to pay additional interest at a rate of two
and one-half percent (2.5%) per quarter (10% per annum) (the “Additional
Interest”) beginning on the date of issuance of this Note and ending on the
maturity date, provided however, that such payment is only required if and only
if the noteholder elects to convert the entire balance of the September 2021
Note into the Company’s common stock on or prior to maturity. As the contingent
event is not based on creditworthiness, such feature is not clearly and closely
related to the host instrument and accordingly must be bifurcated and
recognized as a derivative liability and a debt discount on the September Note
at its inception. The fair value of the contingent interest derivative
liability was $433,000 at note inception (September 17, 2021). The fair value
of the contingent interest derivative liability was $613,000 and $924,000 at March
31, 2026 and December 31, 2025, respectively, and is recognized as a derivative
liability in the consolidated balance sheet. The change in the fair value of
the derivative liability for the three months ended March 31, 2026 and 2025 of
$(311,000) and $(21,000), respectively, was recorded to other expense for the three
months ended March 31, 2026 and 2025. The amortization of the original $433,000
debt discount of $27,000 was recorded as additional interest expense for the
three months ended March 31, 2025. The debt discount was fully amortized at
December 31, 2025. On December 20, 2021, the second of the two promissory notes under
the Loan Agreement was executed and delivered, (the “December 2021 Note”) to
evidence the second loan in the principal amount of $10,000,000. The December
2021 Note had an original maturity date of December 20, 2025, is prepayable at
the option of the Company in whole or in part at any time and is convertible
into the Company’s common stock at a conversion price equal to $5.43 per share
at the option of the noteholder. The December Note bears interest at the rate
of two percent (2%) per annum, compounded annually with an effective interest
rate of approximately 3%. For the three months ended March 31, 2026 and 2025,
approximately $54,000 and $53,000, respectively, of interest expense was
accrued and included with the principal in the financial statements. The December 2021 Note also includes a contingent interest
component that requires the Company to pay additional interest at a rate of two
and one-half percent (2.5%) per quarter (10% per annum) (the “Additional
Interest”) beginning on the date of issuance of this Note and ending on the
maturity date, provided however, that such payment is only required if and only
if the noteholder elects to convert the entire balance of the December 2021
Note into the Company’s common stock on or prior to maturity. As the contingent
event is not based on creditworthiness, such feature is not clearly and closely
related to the host instrument and accordingly must be bifurcated and
recognized as a derivative liability and a debt discount on the December Note
at its inception. The fair value of the contingent interest derivative
liability was $415,000 at note inception (December 20, 2021). The fair value of
the contingent interest derivative liability was $1,036,000 and $1,358,000 at
March 31, 2026 and December 31, 2025, respectively, and is recognized as a
derivative liability in the consolidated balance sheet. The change in the fair
value of the derivative liability for the three months ended March 31, 2026 and
2025. of $(322,000) and $(43,000), respectively was recorded to other expense
for the three months ended March 31, 2026 and 2025. The amortization of the
original $415,000 debt discount of $26,000 was recorded as additional interest
expense for the three months ended March 31, 2025. The debt discount was fully
amortized at December 31, 2025. The Company’s contractual cash obligations related to the
outstanding convertible notes payable is a repayment of the September 2021 Note
of the $10,000,000 plus accrued interest on June 30, 2027 and a repayment of
the December 2021 Note of the $10,000,000 plus accrued interest on June 30,
2027, unless converted at the option of the noteholder.
