Future Outlook

Sky Harbour expects to continue drawing from the JPMorgan Facility in the coming weeks and months to accelerate its construction program. Phase I construction at Hudson Valley Regional Airport (POU), Orlando Executive Airport (ORL), and Trenton-Mercer Airport (TTN) is expected to start in the coming months. The company's focus for 2026 is on scaling operations, with over 1,000,000 square feet of new hangar development fully funded. The 23 ground leases are expected to include approximately 4 million in aggregate rentable square feet once fully developed.

Management Comments

• "The Company is generating operating cash at an increasing rate as additional hangar campuses come online."
• "More than 1,000,000 square feet of new hangar development is fully funded, and our construction resources are prepared to meet the upcoming surge with growing speed and cost-efficiency."
• "The Sky Harbour HBO offering is the solution of choice for the country's top flight departments."
• "Our focus for 2026 is scale."

Industry Context

StockSavvy.ai notes that Sky Harbour's expansion in aviation infrastructure, particularly for business aircraft, aligns with a growing trend of private aviation demand. The company's strategy of building a nationwide network of Home Base Operator (HBO) campuses positions it to capitalize on the increasing need for dedicated, high-quality hangar space and services, differentiating itself from traditional FBOs. This growth trajectory suggests a strong market fit and potential for continued leadership in a specialized, high-value segment of the aviation industry.

Comparison to Industry Standards

• Sky Harbour's 87% consolidated revenue growth in 2025 significantly outpaces the general aviation market's average growth, which typically ranges from 5-10% annually, indicating strong market penetration and demand for its specialized HBO model.
• Achieving operating cash flow breakeven by year-end 2025 is a critical milestone, demonstrating progress towards financial self-sufficiency, a metric often sought by investors in high-growth infrastructure companies.
• The successful securing of $350 million in new financing (JPMorgan Facility and 2026 Series Bonds) at competitive rates (SOFR-based with 4.73% swap, and 6.00% fixed) suggests strong lender confidence in Sky Harbour's business model and asset base, especially when compared to the higher cost of capital often faced by smaller, less established infrastructure developers.
• The rapid development and operationalization of new campuses (DVT, APA, ADS completed in 2025) and high occupancy rates (near 100% for older campuses) demonstrate efficient execution, comparable to best-in-class real estate developers in specialized niches.

Stakeholder Impact

• Shareholders: Positive impact due to strong financial performance, achievement of breakeven guidance, successful funding for future growth, and expansion of the asset base.
• Creditors (J.P. Morgan, 2021 Series Bondholders): Positive impact due to improved operating cash flow, compliance with debt service coverage ratios for the Obligated Group, and the company's ability to secure additional financing, enhancing overall financial stability.
• Customers (Business Aircraft Owners/Operators): Positive impact from the expansion of the HBO network, offering more locations and high-quality infrastructure, potentially leading to better service and availability.
• Employees: Potential positive impact from increased construction and development activity, suggesting job stability and growth opportunities within the company.

Next Steps

• Continue to draw from the JPMorgan Facility in the coming weeks and months to accelerate the construction program.
• Start construction of Phase I at POU, ORL, and TTN in the coming months.
• Focus for 2026 is on scaling operations.
• Future capital expenditures on remaining construction at OPF phase II and Addison phase II to be covered from expected Obligated Group revenues, proceeds of the 2026 Series Bonds, and capital contributions from the Company as needed.

Key Dates
