Material Changes and Covenants
The Company has entered into a new credit agreement with JPMorgan Chase Bank, N.A., as administrative agent. This represents a significant expansion of the Company's capital structure for future development. Key covenants include:
- Leverage Ratio: Borrowers must maintain a leverage ratio of 65% (total indebtedness divided by borrowing base value).

- Guarantees: Obligations are guaranteed by Sky Harbour LLC, Sky Harbour Holdings II LLC, and Sky Harbour Holdings III LLC. The Company provides a non-recourse carveout guarantee for limited circumstances such as misconduct.
- Interest Rate Hedging: Once the outstanding principal reaches $25 million, Borrowers must hedge 50% of their interest rate risk.
Outlook, Risks, and Contingencies
The facility is designed to fund "Hangar Projects" subject to phased eligibility criteria. The filing notes several risks and contingencies:
- Prepayment Triggers: Events such as the cancellation of construction contracts, termination of ground leases, or material violations of environmental law may trigger prepayments or disqualify projects from further loans.
- Revenue Release Restrictions: Excess revenues from the 2021 Master Indenture cannot be released until substantial completion of the 2021 Projects is achieved.
- Compliance: Mandatory prepayments are required if the Company fails to comply with the Leverage Ratio.
Investor Verification Checklist
- Verify the specific list of airports and hangar projects eligible for funding under the new facility.
- Confirm the status of the "2021 Projects" to understand when excess revenues from the Master Indenture may become available.
- Monitor the Company's leverage ratio and DSCR compliance, particularly as the facility matures or projects reach substantial completion.
- Review the terms of the non-recourse carveout guarantee to understand the extent of the parent company's liability.
- Assess the impact of the 1.50% upfront fee and ongoing commitment fees on the Company's cash flow.
