Insights

Credit and capital structure analyst

Sky Harbour adds $10 million unsecured debt with equity sweetener on defined amortization schedule.

The financing provides Sky Harbour Group with $10 million via an unsecured, non-convertible promissory note issued by subsidiary Sky Harbour LLC to Yorkville. The 7.75% annual interest rate and June 8, 2027 maturity are typical for private credit, with a significantly higher 18% rate triggered only upon an event of default.

Beginning on July 8, 2026, the borrower must repay $833,333.33 monthly for twelve months, creating a clear amortization profile. The parent company guarantee increases Yorkville’s protection but also extends recourse to Sky Harbour Group. As part of the deal, the company will issue 40,000 Class A shares in a registered direct offering, effectively acting as an equity incentive to the lender.

The proceeds may be used for working capital and general corporate purposes, indicating general liquidity and operating support rather than a specifically earmarked project. Future financial statements and disclosures will show how this added debt service and the small equity issuance affect leverage, interest expense, and cash generation over the term to June 8, 2027.
