Highlights of the results are:

• Q4 Revenues increased 41% as compared to Q3 2022
• General & Administrative expenses decreased from $3.6 million in Q3 2022 to $2.6 million in Q4 2022
• Strong liquidity and capital resources as of December 31, 2022, including cash, restricted cash, and US Treasury investments of over $180 million¹
• Opening of Nashville Phase 2 campus on October 27, 2022
• Opening of Miami-Opa Locka Phase 1 campus on February 1, 2023

On March 22, 2023, Sky Harbour Capital LLC ("SHC") published an event notice (the "Event Notice") to the holders of the Series 2021 PABs through the website of the Municipal Securities Rulemaking Board via its Electronic Municipal Market Access system at www.msrb.org and on the investor relations section of the website of the Company. Pursuant to Trust Indenture, dated as of September 1, 2021, between the Public Finance Authority and the Bank of New York Mellon, as trustee, the Event Notice included a feasibility study conducted by an independent consultant confirming, based on its reasonable assessment at the time, that the election to modify the scope of the its Senior Special Facility Revenue Bonds (Aviation Facilities Project), Series 2021 to include a project site located in Addison, Texas (the "ADS Project") would increase the projected debt service coverage ratio of SHC. The study may be found at the following link:

The expected improvement in debt service coverage is the result of the Modification and additional measures taken as part of an effort to "recapitalize" the Obligated Group. These measures include the following recently completed actions or developments:

• The Modification as described above;
• Higher tenant lease rental levels and annual escalators;
• Introduction of fuel commissions in tenant leases;
• Transfer of OPF Hangars Landlord LLC as a new subsidiary of SHC, providing annual cash ground lease savings of approximately $0.5 million to the Obligated Group;
• The waiver by Sky Harbour Services LLC of intercompany development, asset management and operating management fees slated to be charged to the Obligated Group during the construction period, an estimated benefit of $13 million to the Obligated Group;
• The active investment and rollover of cash in US Treasury securities at the various funds (construction, reserves) for increased interest income of $4 million; and
• The infusion of $1.2 million in cash from SHG to SHC/Obligated Group completed last January.

We believe these actions, originally announced in September 2022, are intended to fully prevent any potential funding gaps of the 2021 Project deriving from construction inflation. Any overfunding of the 2021 Project, as modified, from these measures will accrue to SHG in the form of released cash from the 2021 PABs waterfall at The Bank of New York Mellon, as trustee, at the end of construction period slated at the end of 2025.

Tal Keinan, Chairman and Chief Executive Officer, commented on the full year results: "Sky Harbour entered a new phase over the past year, conducting simultaneous flight operations on multiple fields (Houston, Nashville and Miami) for the first time. We commenced construction in two key jurisdictions (Denver and Phoenix) and executed a new ground lease in Dallas, one of the nation's most attractive business aviation markets. The Sky Harbour organization has grown significantly, notably the Site Acquisition Team, responsible for driving the coming year's ambitious growth plans. Our Development Team has managed an inflationary construction environment through flexibility and innovation. The Sky Harbour Finance Team has guided the firm through challenging economic conditions, successfully avoiding the liquidity and counterparty risks of the past quarter. Taking three airfields through the full development cycle, site acquisition through flight operations, has given Sky Harbour the opportunity to validate its business model, refine its methods and processes, and position its team for accelerated growth in the years ahead."

Keinan also commented on the completion of the Modification: "Confronted with the past year's inflation in construction costs, we took measures to preempt any potential funding gaps in the Obligated Group portfolio. We are stewards to both our stock and bondholders. Continually enhancing debt service coverage in the Obligated Group is a key corporate goal."

Sky Harbour campuses are open and operating at Houston's Sugar Land Regional Airport, Nashville International Airport and Miami Opa-Locka Executive Airport. Sky Harbour recently broke ground on new campuses at Denver Centennial Airport and Phoenix Deer Valley Airport.
