EXPLANATORY NOTE

Rapidbuilt Acquisition

On May 12, 2023 (the “Option Exercise Date”), Sky Harbour LLC (“Sky”), a subsidiary of Sky Harbour Group Corporation (the “Company”), exercised its option to purchase a 51% equity interest in Overflow Ltd., a Texas limited partnership (“Overflow”), and its wholly-owned subsidiary, Rapidbuilt, Inc., a Texas corporation (“Rapidbuilt”), for nominal consideration (the “Rapidbuilt Acquisition”). As a result of the Rapidbuilt Acquisition, Weatherford Steel Buildings Holdings LLC, a Delaware limited liability company and wholly-owned subsidiary of Sky (“WSBH”), owns a 50% limited partnership interest in Overflow, and Weatherford Steel Buildings GP LLC, a Delaware limited liability company and wholly-owned subsidiary of Sky (“WSB GP”), owns a 1% general partnership interest in Overflow. 

Rapidbuilt is a manufacturer of pre-engineered steel buildings that Sky previously entered into a vendor agreement to supply hangar buildings related to Sky's development projects (the “Vendor Supply Agreement”). Rapidbuilt and Sky's strategic partnership has resulted in a standard set of proprietary prototype hangar designs, which are intended to deliver high-quality business aviation facilities, lower construction costs, minimize development risk, expedite permit issuance, and facilitate the implementation of refinements across Sky's portfolio. 

Item 1.01. Entry into a Material Definitive Agreement.

Guaranty Agreement and Overflow Loan Amendment

In connection with the Rapidbuilt Acquisition, Sky and Vista Bank (the “Lender”) entered into a consent, waiver, and second amendment (the “Loan Amendment”) and a guaranty agreement (the “Guaranty Agreement”) associated with the senior loan agreement between Overflow and Rapidbuilt (collectively, the “Borrowers”), and the Lender (the “Overflow Loan”). Pursuant to the Loan Amendment, (i) the Lender consented to the change in control with respect to the Borrowers; (ii) the Lender waived any pre-existing events of default on the part of the Borrowers; (iii) the Lender agreed to release certain borrowed funds held in reserve, subject to specified terms and conditions; and (iv) the Borrowers agreed to certain reserve enhancement obligations, including the ability to repay principal early at the sole discretion of the Borrowers. Pursuant to the Guaranty Agreement, all of the Borrowers’ obligations under the Overflow Loan will be guaranteed by Sky.

The Overflow Loan was originated in December 2020 between the Borrowers and the Lender and has approximately $10.0 million of principal outstanding as of the Option Exercise Date. The Overflow Loan accrues interest at a per annum rate equal to 3.00% above the three-month secured overnight financing rate published for first day of each calendar quarter by the Federal Reserve Bank of New York. Interest is payable on a monthly basis, and the Borrowers agreed to make certain reserve enhancement payments on January 1, April 1, July 1, and October 1 of each calendar year. The maturity date of the Overflow Loan is December 1, 2025. The Overflow Loan is secured by the (i) accounts, (ii) intellectual property, (iii) equipment, (iv) inventory, (v) vehicles, and (vi) property of the Borrowers, and contains customary affirmative and negative covenants. 

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The disclosure contained in Item 1.01 of this Current Report on Form 8-K under the heading “Guaranty Agreement and Overflow Loan Amendment” is incorporated by reference in this Item 2.03.

Item 8.01. Other Events.

(b) Pro Forma Financial Information. In accordance with Item 9.01(b), the pro forma financial information is not “significant” and therefore not required to be filed pursuant to Article 11 of Regulation S-X.
