Loans Payable | 12. Loans Payable As a result of the Acquisition of VCN, the Company acquired interest-free or below-market interest rate loans (0%-1%) extended by Spanish governmental institutions of Ministerio de Ciencia, Innovacion y Universidades (RETOS loan) and ACC10 Generalitat de Catalunya (NEBT loan). The maturities of these loans are between 2024 and 2028. As a result of the Acquisition, the Company maintains a restricted cash collateral account of $46,000 relating to the RETOS loan, which is reflected as a non-current asset on the balance sheet. During September 2024, the Company announced that its THERICEL project had been awarded €2.28 million (approximately $2.54 million) from the National Knowledge Transfer Program of the Spanish government’s Ministry of Science, Innovation & Universities to support a collaboration between the Company and the Universitat Autònoma de Barcelona (“UAB”) to advance the Company’s THERICEL suspension cell platform for the clinical manufacture of adenovirus- and adeno-associated virus (“AAV”) therapies. Under the award, the Company (via its wholly owned subsidiary, Theriva Biologics SL) received an unsecured loan (the “Loan”) of €1.3 million (approximately $1.4 million) as a lump sum payment on January 17, 2025 which bears interest at a rate of 4.015% and is to be repaid over 7 years commencing three years from the date of award. ​
