• The Company continues to maintain strong liquidity and capital resources. As of December 31, 2023, cash, restricted cash, and US Treasury investments amounted to approximately $172 million, of which $99 million resided at SH Capital.

Recent noteworthy events include:

• New ground lease at SJC, encompassing an existing hangar facility to be made operational over the coming several weeks, and land for additional future development.
• New ground lease at ORL, with expected construction commencement in Q2 2025.
• Construction of Phases 1 in Denver, Phoenix, and Dallas delayed by 3-4 months, with an estimated $26 - $28 million non-recurring remediation cost. Revised expected completion dates are December 2024, February 2025, and March 2025, respectively.
• Houston, Nashville, and Miami campuses are stabilized at 95% leased, with potential full occupancy expected at over 100%. The San Jose facility is 58% pre-leased, with an expected operations start date of April 1, 2024.

Site Acquisition Update

The Company and the City of San Jose, California executed a 7-acre ground lease at SJC (lease #10) which includes approximately 60,000 square feet of existing hangar and office space, over 100,000 square feet of aviation ramp, and 120 land-side automobile parking stalls. The initial term of the lease is twenty years, and future development is expected to increase hangar square footage by approximately 75%. San José Mineta International Airport serves the south San Francisco Bay Area, including Silicon Valley.

The Company and the Greater Orlando Airport Authority executed a ground lease at Orlando Executive Airport (ORL) (lease #11). The 50-year ground lease encompasses twenty acres, accommodating more than 200,000 square feet of hangar, with Phase 1 construction expected to begin in summer 2025. The Orlando Executive Airport is the premier general aviation airport in Central Florida and is located approximately three miles east of downtown Orlando. The Greater Orlando area is the second-fastest growing metro center in the country by GDP.

Exclusive ground-lease negotiations are underway at five new target airports. Formal ground lease proposals have been submitted or are pending at an additional eight new target airports.

The Company expects to have executed ground leases at three additional airports by the end of 2024 and an additional six airports by end of year 2025 representing an additional aggregate rentable square footage of more than 2 million square feet, primarily in markets with higher per-square-foot tenant rents than those in the first Obligated Group's six airports.

Construction Update

As previously announced, in December 2023 the Company discovered a flaw in the prototype design employed in the construction of Phases I at Phoenix Deer Valley Airport ("DVT") and Denver Centennial Airport ("APA"), and that was planned to be employed in Phase I at Dallas Addison Airport ("ADS").

Having completed a comprehensive review and prototype-redesign process with a leading national structural engineering firm, the Company is executing a remediation plan, including:

1. Retrofitting significant elements of the DVT and APA structures currently under construction,
2. Modifying the design of ADS structures in pre-construction to conform with Sky Harbour prototype requirements, and
3. Applying the amended SH34 and SH16C prototype design to future projects with the intention of:
   1. Delivering best-in-class 100-year structures of the highest quality and
   2. Standardizing and streamlining procurement, manufacturing and construction in pursuit of shorter development time frames and lower development costs.

Expected remediation costs are between $26 and $28 million, including approximately $16 million at DVT, approximately $8.5 million at APA, and approximately $2.5 million at ADS. Expected delivery dates of these projects are now November 2024 (APA), and February 2025 (ADS) and March 2025 (DVT).

Leasing Update

Sky Harbour's first three campus phases (SGR, BNA and OPF 1) are approximately 95% occupied. Total potential economic occupancy is expected to exceed 100% due to successes in semi-private leasing.

SJC is expected to commence operations on April 1, 2024, and is approximately 58% preleased. SJC tenant rents are reflective of Sky Harbour's tier-1 target markets, with expected revenues from certain initial tenants exceeding $80 per rentable square foot.

Registration of prior PIPE Shares, Replacement of Stand-By Share Sale Program and New "Shelf" Registration

As required under the registration rights agreement with the PIPE common stock investors which closed in November 2023, we have filed a registration statement on Form S-3 registering the Class A common shares, the associated PIPE warrants, and the Class A common shares underlying those warrants. Similarly, the Company has terminated its 10 million share Stock Purchase Agreement, originally dated August 18, 2022, and replaced it with a Stock Selling Agreement ("at the market" or "ATM") with an affiliate of the same broker-dealer of slightly smaller size. The Company did not sell any shares under the original agreement and only intends to sell shares under the new ATM if attractive market opportunities arise.

Equity Cash Infusion into PABs Series 2021 Obligated Group

On March 27, 2024, the Company contributed an additional $27 million of cash equity into its wholly-owned subsidiary Sky Harbour Capital LLC (the Obligated Group) to address the anticipated net funding gap associated with the one-time remediation costs at DVT, APA and ADS.

CEO Remarks

Tal Keinan, Chairman and Chief Executive Officer, commented on 2023 Full year results and other recent events:

"Sky Harbour's efforts to ramp up site acquisition in 2023 are bearing fruit today and should accelerate throughout 2024 and 2025. Having established our baseline unit economics, the Site Acquisition team's focus is shifting to the country's tier-1 metro markets, where excess demand for business aviation hangar space most acutely manifests in higher hangar rents. With prototype design weaknesses addressed rigorously and rectified, we are structuring and growing the Sky Harbour Development Team to accommodate the anticipated scale-up in manufacturing and construction. The Airfield Operations team continues to focus on delivering the most efficient and personalized service suite in business aviation. Sky Harbour took good strides in 2023 in pursuit of its ambition to provide Sky Harbour Residents with the best service at the best facilities on the best airfields in business aviation. We are now gearing up to perform at scale."
