Leases

The Company leases office space in Tulsa, Oklahoma, Seattle, Washington, and Beijing, China. During May 2025, the Company renewed its Beijing, China lease for 24 months with monthly rent at approximately $3 thousand. As a result of this renewal, the Company increased the right-of-use (“ROU”) asset and lease liability by $68 thousand during the six months ended June 30, 2025.

​

During October 2024, the Company entered into a sub-lease agreement to rent office space in Seattle for approximately $2 thousand per month for twelve months. The Seattle lease is considered a short-term lease, as the lease term is 12 months or less from the commencement date. The short-term lease expense for the three and six months ended June 30, 2025 was approximately $5 thousand and $11 thousand, respectively. The short-term lease expense for the three and six months ended June 30, 2024 was approximately $5 thousand and $11 thousand, respectively. The Tulsa and Beijing leases are classified as operating leases, with remaining terms ranging from two years to approximately three years; contractual language requires renewal negotiations to occur at or near termination. These leases are normal and customary for office space, in that, contractual guarantees exist requiring the lessee return the premises to its original functional state.

​

The Tulsa lease contains fixed annual lease payments that increase annually by 2%. The Seattle, Tulsa, and Beijing total monthly minimum rent is approximately $10 thousand, in the aggregate.
