Sky Harbour Group Corporation is issuing 50,000 shares of Class A common stock in a registered direct offering to YA II PN, Ltd. (Yorkville). The shares are being issued as equity consideration in connection with a $15 million non-convertible, unsecured promissory note to Yorkville, so Sky Harbour will not receive any cash proceeds from this stock issuance and will bear related offering expenses.
The Yorkville Promissory Note accrues interest at 7.75% per year (increasing to 18% upon an event of default), matures on June 8, 2027, and requires twelve monthly repayments of $1,250,000 beginning July 8, 2026. The note is guaranteed by Sky Harbour Group Corporation, and the proceeds may be used for working capital and general corporate purposes. Following this issuance, Class A common stock outstanding will be 33,989,673 shares as of December 11, 2025.
Sky Harbour Group Corporation reported that director Walter Jackson will resign from its Board of Directors, effective December 31, 2025.

To fill the vacancy, the Board has appointed Andrew Jody Gessow, age 68, to serve as a director until the 2026 Annual Meeting of Shareholders and as a member of the Audit Committee, both effective upon Jackson’s resignation.

The Board also named Jordan Moelis, a director and Audit Committee member since June 2024, as the new Chairman of the Audit Committee, effective upon Jackson’s resignation.

Sky Harbour Group Corporation reported higher activity in its aviation hangar business while continuing to invest in growth. For the quarter ended September 30, 2025, revenue was $7.3 million (rental $5.7 million, fuel $1.6 million), up from $4.1 million a year ago. The company recorded an operating loss of $7.7 million and a net loss attributable to shareholders of $1.9 million (basic EPS $(0.06)), reflecting higher ground lease, compensation, and depreciation as newly built campuses ramp. For the nine months, revenue reached $19.5 million and net income attributable to shareholders was $9.2 million, driven by a $22.3 million unrealized gain from warrant remeasurement.
On the balance sheet as of September 30, 2025, cash was $23.5 million and restricted cash $13.0 million. Total assets were $558.0 million, including constructed assets, net, of $266.0 million, and cost of construction of $42.2 million. Total liabilities were $394.2 million, including bonds payable, net, of $162.8 million and a warrants liability of $23.9 million. The company executed a term loan facility up to $200 million on September 4, 2025 to fund hangar projects; no loans were outstanding as of quarter end. Under its ATM program, Sky Harbour sold 20,472 Class A shares year‑to‑date for $281 thousand.
Sky Harbour Group Corporation subsidiary Sky Harbour Capital II entered a credit agreement providing a term loan facility of up to $200 million, extendable to $300 million with lender approval. Loans will fund construction and operation of airport hangar projects and are secured by project real estate, equity pledges and certain project revenues. The loans mature on September 4, 2030; none are outstanding as of the filing. Interest is set as "80% of the sum of SOFR and 0.10%, plus 200 basis points," with interest optionally capitalizable for the first three years. Borrowers paid an upfront fee equal to 1.50% of $200 million and will pay quarterly commitment fees. When outstanding loans reach $25 million, borrowers must hedge 50% of interest rate risk. Parent, holdco and limited company guarantees apply, and a Non-Recourse Carveout Guaranty can require the company to guarantee obligations in certain specified circumstances.
Sky Harbour Group Corporation filed an 8-K reporting two items: it furnished a press release and an investor presentation announcing financial results for the three and six months ended June 30, 2025, and it disclosed the departure of its Chief Operating Officer, Willard Whitesell. The company says the press release and presentation are furnished as Exhibits 99.1 and 99.2 and are summary information to be read with its SEC filings.
In connection with Mr. Whitesell's departure effective August 8, 2025, the company entered a Separation Agreement providing that all unvested restricted stock units (RSUs) will become fully vested as of the Separation Date and will be delivered in shares on a pro rata monthly basis under the original four-year vesting schedule. The filing states the departure was mutual and not due to any disagreement with the company.
Sky Harbour Group Corporation reported notable revenue growth in the quarter: $6.59 million for the three months ended June 30, 2025 versus $3.62 million a year earlier, and $12.18 million for the six months ended June 30, 2025 versus $6.02 million in 2024, driven by higher rental and fuel revenue. Despite rising revenues, operating losses persist: an operating loss of $7.53 million for the quarter and $14.35 million year-to-date, reflecting development costs, campus operating and personnel expenses.
Net income of $14.36 million for the quarter largely reflects a $21.80 million unrealized gain on warrant fair-value remeasurement rather than operating profitability. Balance sheet highlights include $568.1 million of total assets, $167.0 million total equity, $162.7 million of net bonds payable, and $175.4 million of operating lease liabilities. Cash and restricted cash totaled $32.11 million at June 30, 2025 after a $62.25 million decrease driven by construction and investment activity. Portfolio occupancy across operating campuses was 68.9% with 892,318 rentable square feet in operation.
