The Company and its subsidiaries (the “Borrowers”) routinely enter into long-term loan agreements with various lenders for the purpose of financing purchases of aircraft. These loans usually have an initial term between 2 to 15 years and sometimes the Borrowers negotiate with the lenders to extend the maturity date at the end of the initial term. The Borrowers will refinance as needed to meet their respective obligations as they become due within the next 12 months. As the parent, the Company has maintained a positive relationship with the lenders and has not historically had any difficulty refinancing these debt obligations. Based on historical experience and the fact that the Company has not suffered any decline in creditworthiness, it expects that cash on hand and cash earnings will enable it to secure the necessary refinancing. Amendments are executed at times when interest rates and terms are changed. Under these long-term loan agreements, the Borrowers usually pay principal and interest payments each month, followed by a balloon payment of all unpaid principal and accrued and unpaid interest due upon maturity, and when applicable, a loan origination fee upon execution. Each note payable is collateralized by the specific aircraft financed and is guaranteed by the owners of the Borrowers.

A lender may impose a restriction that the outstanding balance of the note may not exceed a percentage of the retail value of the collateral. In the event the outstanding value of the loan exceeds the percentage threshold of the collateralized aircraft, the Borrowers may be required to make a payment in order to reduce the balance of the loan. Pursuant to the loan agreements, the Borrowers must maintain certain debt service ratios (such as cash flow to leverage or certain EBITDA to total borrowings) specific to each lender as long as the Borrowers hold outstanding loans. There were 16 separate loan agreements (each loan agreement includes the initial agreement and amendments if applicable) with note payable balances outstanding as of June 30, 2026, compared to 24 separate loan agreements as of December 31, 2025.

As of June 30, 2026 and December 31, 2025, unamortized debt issuance costs were $194 and $159 for long-term notes payable (excluding convertible note), respectively.

During the three months ended June 30, 2026 and 2025, the Company recorded $7 and $25, respectively, in amortization of long-term debt issuance cost within interest expense. During the six months ended June 30, 2026 and 2025, the Company recorded $65 and $53, respectively, in amortization of debt issuance cost within interest expense in the condensed consolidated statements of operations and comprehensive loss (unaudited).

Total interest expense related to long-term debt (excluding convertible note and VIEs) was $2,371 and $1,619 for the three months ended June 30, 2026 and 2025, respectively, and total interest expense was $4,306 and $3,973 for the six months ended June 30, 2026 and 2025, respectively.

Sale-Leaseback Transactions

In November 2025, the Company sold an aircraft to a third party for approximately $18,500. In connection with the sale, the Company entered into an agreement to lease back the aircraft for a 3-year period. Since the lease agreement provides the Company an option to repurchase the aircraft equal to the greater of $18,500 or the fair market value of the aircraft as of the purchase date, the transaction is accounted for as a failed sale-leaseback. As a result, the aircraft remains on our condensed consolidated balance sheet (unaudited) as of June 30, 2026. The Company recognized $18,500 of the proceeds as a financing obligation as a component of long-term debt.

In May 2026, the Company sold an aircraft to a third party for $4,700. In connection with the sale, the Company entered into an agreement to lease back the aircraft for a 5-year period. Because the lease agreement provides the Company an option to repurchase the aircraft at a price equal to the greater of $4,700 or the fair market value of the aircraft as of the purchase date, the transaction is accounted for as a failed sale-leaseback. As a result, the aircraft remains on our condensed consolidated balance sheet (unaudited) as of June 30, 2026. The Company recognized $4,700 of the proceeds as a financing obligation as a component of long-term debt.

Debt Covenants

Financial covenants contained in the debt borrowings mandate that the Company maintains certain financial metrics, including, but not limited to, debt service coverage ratios, fixed charge cover ratios, or cash flow cover ratios. If the Company is unable to maintain the financial metric, it is a breach of the debt covenant and is considered an event of default. An event of default can result in all loans and other obligations becoming immediately due and payable, including the advance of any sums necessary to cure the event of default, allowing the lenders to seize the collateralized assets, which include aircraft and the debt agreements being terminated. As of December 31, 2025, the Company was not in compliance with certain financial covenants and obtained waiver request letters from the various lenders. Pursuant to the waiver letters, the lenders agreed to waive the financial covenants as of December 31, 2025 through

December 31, 2026. The aggregate balances of outstanding debt obligations for which waiver letters were received were $0 and $8,924 as of June 30, 2026 and December 31, 2025 respectively.

Economic Injury Disaster Loans (“EID”)

In August 2020, the Company executed the standard loan documents required for securing loans offered by the SBA under its EID loan assistance program and received the loan proceeds of $122. The proceeds from the EID Loan must be used for working capital. The EID Loan has a thirty-year term and bears interest at a rate of 3.75% per annum with monthly principal and interest payments being deferred for 12 months after the date of disbursement. On March 11, 2021, the American Rescue Plan Act of 2021 was enacted, which extended the first due date for repayment of EID Loans made in 2020 from 12 months to 24 months from the date of the note. The EID Loan may be prepaid at any time prior to maturity with no prepayment penalties. The Loan Authorization and Agreement and the note executed by the Company in connection with the EID Loan contain events of default and other provisions customary for a loan of this type and the EID Loan is secured by a security interest on all of the Company’s assets.
