Item 1.01Entry into a Material Definitive Agreement

 

As previously disclosed by TransCode Therapeutics, Inc. (the “Company”) in a Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on April 7, 2026, the Company entered into a Standby Equity Purchase Agreement (the “SEPA”) with YA II PN, Ltd., a Cayman Islands exempt limited partnership (“Yorkville”) dated as of April 6, 2026, pursuant to which the Company has the right to sell Yorkville up to $14 million of shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”). In connection with the SEPA, Yorkville also agreed to advance the Company up to $6.0 million, less certain amounts, to be paid in two tranches, in exchange for the Company’s issuance to Yorkville of convertible promissory notes (each, a “Convertible Note” and, together, the “Convertible Notes”). Under the terms of the Convertible Notes, an “Amortization Event” is deemed to occur if the daily VWAP (as defined in the Convertible Notes) of the Common Stock is less than $1.72 (the “Floor Price”) for five trading days during a period of seven consecutive trading days (a “Floor Price Event”). From September 11, 2026 to September 30, 2026, the daily VWAP of the Common Stock was less than the Floor Price for 10 trading days out of 14 trading days.

 

On October 1, 2026, the Company and Yorkville executed a waiver, in which the Company agreed to make a prepayment of $840,975 in accordance with Section 1(f) of the Convertible Notes (the “Prepayment”), which amount includes payment of $759,000 outstanding principal of the Convertible Notes, $75,900 prepayment premium and $6,075 of accrued interest. In consideration for the Prepayment, Yorkville agreed to waive the occurrence of any Amortization Event that may be deemed to have occurred on or prior to September 30, 2026 and to waive any Amortization Event that may be deemed to occur through October 31, 2026. On October 1, 2026, the Company made the Prepayment. Following the Prepayment, the aggregate principal amount outstanding under the Convertible Notes is approximately $4.1 million.

 

Pursuant to the terms of the Convertible Notes, upon the occurrence of an Amortization Event, the Company would be obligated to make monthly payments to Yorkville beginning on the seventh trading day after the date upon which the Amortization Event occurred and continuing on the same day of each successive calendar month in an amount equal to the sum of (i) 18% of the outstanding principal of the Convertible Notes as of the Amortization Event Date (or the outstanding principal if less than such amount), plus (ii) 10% of the principal amount being paid in respect of such Amortization Principal Amount, plus (iii) all accrued and unpaid interest thereunder as of each payment date. Such monthly payments would be required to be made until the entire outstanding principal amount of the Convertible Notes has been repaid, or the obligation of the Company has ceased because the daily VWAP is greater than the Floor Price for 10 consecutive trading days, unless a subsequent Amortization Event occurs.
