Yorkville Convertible Notes

On January 3, 2024, the Company entered into an unsecured note agreement with an unrelated third party, YA II PN, LTD, a Cayman Islands exempt limited partnership (“Yorkville”) in the principal amount of $1,500,000 (the “YA Note-1”). YA Note-1 was issued with a 10% original issue discount. The original principal amount, together with interest of 8%, was payable by the Company on March 15, 2024, and was extended to July 31, 2024. The note had an outstanding principal balance of $1,235,178 with $150,000 of the debt discount fully amortized to interest expense as of October 31, 2024. On November 1, 2024, the Company entered into an agreement with Yorkville that completely terminates and replaces YA Note-1 (see the Yorkville Transaction defined below). See Note 8, Capital Structure - Standby Equity Purchase Agreement, for further details.

On November 1, 2024, the Company entered into a Standby Equity Purchase Agreement (“SEPA”) pursuant to which the Company has the right to sell Yorkville up to $20,000,000 of its shares of Company Common Stock, subject to certain limitations and conditions set forth in the SEPA, from time to time during the term of the SEPA (such transaction, the “Yorkville Transaction”). In connection with the SEPA, Yorkville has agreed to advance to the Company in the form of a convertible promissory note (the “Convertible Note”) an aggregate principal amount of up to $1,304,758 (the “Pre-Paid Advance”), which terminated and replaced the $1,235,178 YA Note-1 outstanding balance discussed above. The Convertible Note bears an interest rate of 8% per annum and is convertible in whole or in part at any time by Yorkville into shares of common stock of the Company at a conversion price determined based on the lower of the lower of (i) $1.00 per common share (the “Fixed Price”), or (ii) 95% of the lowest daily volume weighted average price during the five consecutive trading days immediately preceding the conversion date (the “Variable Price”), but which Variable Price shall not be lower than the floor price of $0.80 (the “Floor Price”). The Convertible Note matures on November 1, 2025. During the three months ended March 31, 2025, the Company recorded amortization of debt discount in the amount of $76,555 for the Convertible Note.

On January 2, 2025, Yorkville elected to convert a portion of the outstanding principal balance on YA Note-1, the convertible promissory note with an outstanding principal balance of $1,304,758. Yorkville converted $219,758 of the principal balance and $19,446 of accrued interest into 81,877 shares of common stock at a conversion price of $2.92 per share. After conversion, the principal balance of the note has a remaining balance of $1,085,000.

The Company shall make monthly payments beginning on the 7th trading day after either (i) the daily VWAP is less than the Floor Price then in effect for five trading days during a period of seven consecutive trading days (a “Floor Price Event”), or (ii) the Company has issued to Yorkville, pursuant to the transactions contemplated in the Convertible Note and the SEPA, in excess of 99% of the common shares available under the rules or regulations of Nasdaq Stock Market LLC (the “Exchange Cap”), where applicable (an “Exchange Cap Event”), (the last day of each such occurrence, an “Amortization Event Date”) and continuing on the same day of each successive Calendar Month until the entire outstanding principal amount shall have been repaid. Each monthly payment shall be in an amount equal to the sum of (i) $250,000 of principal in the aggregate among the Convertible Note and all other notes (or the outstanding Principal if less than such amount) (the “Amortization Principal Amount”), plus (ii) a payment premium equal to 5% in respect of such principal amount, provided that, the payment premium equal to 5% shall not apply in respect to any amount that is paid directly from an Advance from the SEPA, and (iii) accrued and unpaid interest hereunder as of each payment date. The obligation of the Company to make monthly prepayments related to an Amortization Event shall cease (with respect to any payment that has not yet come due) if at any time after the Amortization Event Date (A) in the event of a Floor Price Event, on the date that is the 7th consecutive Trading Day that the daily VWAP is greater than 110% of the Floor Price then in effect, or (B) in the event of an Exchange Cap event, the date the Company has obtained stockholder approval to increase the number of common shares under the Exchange Cap and the Exchange Cap no longer applies unless a subsequent Amortization Event occurs.

The SEPA is an equity-linked contract that does not qualify for equity classification and is accounted for as a derivative liability recognized at fair value. Any changes in fair value between the carrying amount of the forward issuance contracts and the settlement amounts will be recognized in other income (expense) in the consolidated statements of operations. As of March 31, 2025 and December 31, 2024, the fair value of the SEPA was $635,489 and $1,041,484, respectively. For the three months ended March 31, 2025, the Company recognized a gain on the change in fair value of derivative liability in the amount of $405,995, in the Company’s condensed consolidated statements of operations.

The following table presents information about the Company’s derivative liability that is measured at fair value on a recurring basis at March 31, 2025 and December 31, 2024 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

The derivative liability is accounted for as a liability in accordance with ASC 480 and are presented within derivative liability in the accompanying condensed consolidated balance sheets. The derivative liability is measured at fair value at inception and on a recurring basis, with changes in fair value presented in the condensed consolidated statements of operations.

The derivative liability was valued using a binomial lattice model, which is considered to be a Level 3 fair value measurement. The binomial lattice model’s primary unobservable input utilized in determining the fair value of the derivative liability is the step factors input, assumed price movement, and probabilities assigned to them.

The following table provides quantitative information regarding Level 3 fair value measurements for the derivative liability:

The following table presents the changes in the fair value of derivative liability:

There were no transfers in or out of Level 3 from other levels in the fair value hierarchy during the three months ended March 31, 2025.

On January 16, 2025, the Company entered into a convertible promissory note with YA II PN, LTD, a Cayman Islands exempt limited partnership (“Yorkville”), in the original principal amount of $1,100,000. Interest shall accrue on the outstanding balance of the note at an annual rate equal to 8%, subject to an increase to 18% upon an event of default as described in the note. The maturity date of the note is December 31, 2025. Yorkville may convert the note into shares of Common Stock at any time at a conversion price equal to the lower of (i) $20.00 (the “Fixed Price”) or (ii) a price per share equal to 95% of the lowest daily VWAP during the 5 consecutive trading days immediately prior to the conversion date of the note (the “Variable Price”), but which Variable Price shall not be lower than a floor price of $1.00 per share (the “Floor Price”). The Company internally refers to this note at YA Note-2.

If an Amortization Event occurs, then the Company shall make monthly payments beginning on the later of the 7th Trading Day after the Amortization Event Date, and any the date that is six months from the Issuance Date, and continuing on the same day of each successive calendar month until the entire outstanding principal amount shall have been repaid. Each monthly payment shall be in an amount equal to the sum of (i) $250,000 of principal in the aggregate among this Note (or the outstanding principal if less than such amount) (the “Amortization Principal Amount”), plus (ii) a payment premium equal to 5% in respect of such Amortization Principal amount. The obligation of the Company to make monthly prepayments shall cease (with respect to any payment that has not yet come due) if any time after an Amortization Event (a) if the Amortization Event is due to the Floor Price, the daily VWAP is greater than the 110% of the Floor Price for a period of seven consecutive trading days, and (b) if the Amortization Event is due to the Exchange Cap, the date the Company has obtained stockholder approval to increase the number of Common Shares under the Exchange Cap and/ or the Exchange Cap no longer applies, in either case unless a subsequent Amortization Event occurs.

Additionally, the Company, at its option, shall have the right, but not the obligation, to redeem early a portion or all amounts outstanding under the note at a redemption amount equal to the outstanding principal balance being repaid or redeemed, plus a 5% prepayment premium, plus all accrued and unpaid interest; provided that (i) the Company provides Yorkville with no less than ten trading days’ prior written notice thereof and (ii) on the date such notice is issued, the VWAP of the Common Stock is less than the Fixed Price.
