Leases [Abstract] |
Equipment and Facility Leases | 12. EQUIPMENT AND Facility LEASES The Company has historically entered into lease arrangements for its facilities. As of June 30, 2026, the Company had four operating leases with required future minimum payments. The Company determined the classification of these leases to be operating leases and recorded right-of-use assets and lease liabilities as of the effective date. The Company’s leases generally do not include termination or purchase options. Finance Leases The Company entered into an agreement with an equipment leasing company in 2018, which provided up to $2.5 million for equipment purchases in the form of sale and leasebacks or direct leases. As of June 30, 2026, the Company has two active leases from the leasing company. The terms of the leases are three years and afterwards provide for either annual extensions or an outright purchase of the equipment. The Company entered into an agreement with another equipment leasing company in the second quarter of 2023. As of June 30, 2026, the Company had one active lease from this leasing company. In June 2024, the Company entered into two new finance lease agreements with another leasing company. The terms of these lease are three years and afterwards provide for either annual extensions or an outright purchase of the equipment. The equipment leases require three advance rental payments to be held as security deposits. The security deposits held amounted to approximately $0.1 million as of June 30, 2026 and December 31, 2025, respectively, and are included in other non-current assets on the condensed balance sheets. Operating Leases The Company has an operating lease for office space in Birmingham, Alabama, which was modified and expanded in March 2024 for a 60-month term ending in March 2029, with an option to extend five years, resulting in an increase to both the right-of-use assets and operating lease liabilities. Throughout the term of the lease, the Company is responsible for paying certain costs and expenses, in addition to the rent, as specified in the lease, including a proportionate share of applicable taxes, operating expenses and utilities. In April 2025, the Company terminated its operating lease for additional unutilized office space in Birmingham, Alabama. The Company paid a one-time termination fee of $0.1 million and paid five monthly payments of $20,000, beginning on June 1, 2025. As of October 1, 2025, there were no payments remaining. The Company has an operating lease for office space in New York, New York, with a term that commenced on September 15, 2021, and continues through March 2027. Throughout the term of the lease, the Company is responsible for paying certain costs and expenses, in addition to the rent, as specified in the lease, including a proportionate share of applicable taxes, operating expenses and utilities. The Company has identified an embedded lease within the University of Louisville Manufacturing Services Agreement, as the Company has the exclusive use of, and control over, a portion of the manufacturing facility and equipment of the facility during the contractual term of the manufacturing arrangement. The commencement date of the embedded lease was August 4, 2022 and it continues through August 2028. The operating leases require security deposits at the inception of each lease. The security deposits amounted to $0.2 million as of June 30, 2026 and December 31, 2025. As of June 30, 2026 and December 31, 2025, $0.2 million was included in restricted cash.
