Sky Harbour Group Corporation completed a $150 million financing through tax-exempt revenue bonds issued for its subsidiary Sky Harbour Capital III LLC. The Series 2026 Bonds carry a 6.000% interest rate, paid semi-annually, with a mandatory tender on January 1, 2031 and final maturity on July 1, 2060.
The bonds are secured by a loan to the subsidiary and residual cash flows from certain projects, and are structurally subordinate to existing 2021 revenue bonds and a term loan facility of up to $200 million.

The company will not receive any cash proceeds from this share issuance, which serves as consideration connected to the note.
Sky Harbour recently entered into two Yorkville promissory notes totaling $25 million in principal, each bearing 7.75% annual interest and maturing on June 8, 2027, with scheduled monthly repayments beginning July 8, 2026. As of January 30, 2026, 34,031,380 Class A shares were outstanding, rising to 34,071,380 after this offering. The filing highlights that Sky Harbour already carries substantial debt, including $166.3 million of Series 2021 Bonds, a term loan facility of up to $200 million and an expected $150 million Series 2026 bond issuance, and warns that high leverage and secured debt covenants could increase default and foreclosure risks. The company also notes that prior and potential future equity and equity-linked issuances, including 7,911,580 shares sold in 2024 and 50,000 shares issued to Yorkville in 2025, may dilute existing holders and pressure the stock price.

Starting July 8, 2026, the borrower must make twelve monthly repayments of $833,333.33 toward the outstanding balance. Sky Harbour Group guarantees the obligations under a separate guaranty.

Sky Harbour Group Corporation amended a key credit agreement and related guaranty for its subsidiaries, setting detailed conditions for when surplus funds and excess revenues can be released and used across the group. On January 8, 2026, Sky Harbour Capital II LLC drew approximately $13 million under the facility to reimburse prior capital spending at Bradley International Airport and for other general corporate purposes, leaving about $187 million of borrowing capacity.
The amendments allow surplus funds and certain excess revenues to be distributed for specified uses, including parent-level expenses, debt service and approved hangar projects, once dates tied to January 1, 2027 and project milestones are reached and a 2.00 to 1.00 debt service coverage ratio is maintained.
