The key risks to Sky Harbour (NYSE: SKYH) are primarily related to its aggressive growth strategy, significant debt burden, and the challenges inherent in its real estate development model.

1. Execution Risk, Development Costs, and Path to Profitability: Sky Harbour is pursuing an ambitious expansion plan, with its growth heavily reliant on the "execution/timing of new campuses" and a "rapid campus rollout." The company is currently "unprofitable with high leverage" and has reported a "TTM net loss of $32.7M" due to substantial "heavy development costs." The firm is "investing heavily to fund its expansion," with approximately "$150–175M of new funding (debt or equity)" planned for 2025 to complete its pipeline of campuses. This highlights the significant risk associated with the company's ability to efficiently manage these development projects, control costs, and ultimately achieve profitability.
2. High Leverage and Financing Dependence: Sky Harbour's balance sheet "carries high leverage (Debt/Equity >200%)", exposing it to "the risk of default under our debt obligations." The company's continued growth is contingent on its "access to external sources of capital, and our ability to obtain financing or access capital markets may be limited." This substantial debt and ongoing need for external funding introduce a significant financial risk to the business.
3. Competition for Prime Airport Land: A core aspect of Sky Harbour's business model is securing "scarce 'buildable land on existing airports' niche." However, the company faces "potential competition over prime airport sites", and its growth strategy "depends in part upon our ability to enter into new ground leases at airports." The ability to continuously acquire suitable land on favorable terms is crucial for its expansion and presents an ongoing operational risk.

Sky Harbour (NYSE: SKYH) is a real estate development and operating company that specializes in private aviation infrastructure, primarily focusing on developing, leasing, and managing general aviation hangars for business aircraft in the United States. They offer "home-basing hangar campuses" that include private and semi-private hangars, along with a suite of services for aircraft owners and operators, such as private terminals, ground handling, concierge services, and maintenance support.

The addressable market for Sky Harbour's main products and services can be identified within the broader aircraft hangar market, with a specific focus on the private and business aviation sectors.

• The North America Aircraft Hangar Market was valued at approximately USD 346 million in 2023. This market is driven by increasing investments in aviation infrastructure and the growing demand for Maintenance, Repair, and Overhaul (MRO) facilities. North America holds the largest share in the global aircraft hangar market, and the United States alone accounted for over 88.50% of the North American aircraft hangar market in 2024.
• Globally, the private hangar construction market size stood at USD 5.34 billion in 2024 and is projected to reach an estimated USD 9.15 billion by 2033, growing at a Compound Annual Growth Rate (CAGR) of 6.2%. This growth is fueled by increasing private aircraft ownership and the modernization of aviation infrastructure worldwide.

1. Expansion of Hangar Campus Network: Sky Harbour is aggressively expanding its footprint across the United States by developing and opening new "Home Base Operator" (HBO) campuses. The company plans to grow its operational campuses from nine to a projected 23 by the end of 2025, with key expansions in major markets such as Phoenix, Dallas, Denver, New York, Florida, and Texas. This significant increase in available hangar space is a primary driver for future revenue.
2. Increased Occupancy and Leasing of New Facilities: As new hangar campuses become operational, the leasing up of these facilities to business jet owners and operators will directly contribute to revenue growth. The company has seen increased revenues from incorporating operations from recent acquisitions, such as the Camarillo campus, and anticipates step-function increases in revenue as new campuses are leased and rental income commences.
3. Higher Rental Rates and Premium Lease Pricing: Sky Harbour expects revenue growth to be driven by higher rental rates upon lease renewals. The company's unique business model, which focuses on high-end, boutique private hangar space at key airports with limited developable land, supports premium lease pricing and robust net margins.
4. Growth in Fuel Sales and Ancillary Services: In addition to hangar rentals, revenue is also generated from fuel sales and other services provided to aircraft owners and visitors. The company's earnings reports indicate growth in both rental and fuel revenues, highlighting the importance of these ancillary offerings.
