Subsequent Events	16. Subsequent Events Financing Related Transactions As of September 30, 2025, the Company recorded a $6.4 million liability in accounts payable and accrued expenses due to the March 2025 Private Placement Purchasers. Such liability declined by $1.3 million from September 30, 2025 to October 27, 2025 due to 1) a $0.9 million reduction as a result of the reselling of securities acquired in the March 2025 Private Placement by certain March 2025 Private Placement Purchasers, which was recorded as a reduction of the liability that would have been settled in cash, with a corresponding increase to stockholders’ equity, and 2) a payment of $0.4 million to the March 2025 Private Placement Purchasers subsequent to September 30, 2025, with 0.6 million shares of the Company’s common stock returned and cancelled under the terms of the Letter Agreement. On October 28, 2025, the Company entered into an amendment to the Letter Agreement and the Support Letters with certain March 2025 Private Placement Purchasers (the “Amendment Agreement”), pursuant to which (a) the Support Letters were terminated other than with respect to the participation rights granted therein, and (b) the repayment mechanism under the Letter Agreement was modified. As modified, the Company is no longer required to use 90% of the proceeds from any subsequent financing to repay the March 2025 Private Placement Purchasers. Instead, the Company is only required to retain sufficient funds in an interest bearing account to cover such repayment obligations and make such repayments upon request by any March 2025 Private Placement Purchaser who executed the Amendment Agreement until each such purchaser has received cash either from the Company or from reselling securities acquired in the March 2025 Private Placement in an amount equal to 115% of the purchase price such purchaser paid in the March 2025 Private Placement. If such requests are made, the requesting purchaser must return shares acquired in the March 2025 Private Placement at a value of $0.66 per share.
