Sky Harbour Group Corp

What they do

The company designs, builds, and manages private and semi-private hangar campuses, called Home Base Operator (HBO) campuses, at airports in markets with high hangar demand. Its facilities feature private hangars, configurable lounge and office suites, dedicated line crews, climate control, and no-foam fire suppression. Revenue is primarily from long-term rental agreements, providing forward visibility of cash flows.

Revenue drivers

• Stabilized campus leasing — Higher-than-forecast revenue per square foot; economic occupancy reached as high as 132% at one campus, with average revenue escalation of 19% on re-lease for trailing 12 months as of August 1, 2026.
• Phase 1 and Phase 2 campus leases — OPF combined occupancy 80% with all 2026 leases at Tier-1 rates; ADS Phase 1 98%, DVT Phase 1 76%, APA 44%; SJC Phase 1 132% economic occupancy, Phase 2 100% pre-leased.
• Construction completion and new campus openings — New campuses and phases coming online, such as OPF Phase 2 (opened May 2026) and ADS Phase 2 (expected year-end 2026), add to rentable space and revenue.

Recent performance

For Q2 2026, consolidated revenue increased approximately 50% year-over-year and 13% sequentially. Net cash provided by operating activities was about $0.5 million, the first quarter of positive operating cash flow. Quarterly revenue reached $9.9 million in Q2 2026, up from $7.3M in Q3 2025. Constructed assets and construction in progress exceeded $393 million at quarter-end, a year-to-date increase of $65 million. Consolidated cash and US Treasuries totaled $206.9 million, excluding $40 million in proceeds from a registered direct common stock issuance settled after quarter-end.

Strategy

The company intends to capitalize on hangar supply constraints by replicating prototype hangar designs across multiple airports, lowering construction costs and expediting permitting. It targets high-end tenants in markets with a shortage of private and FBO hangar space. Funding comes from public bond markets and bank debt, including the Series 2026 Bonds and a committed JP Morgan drawdown facility. Management reaffirmed guidance for year-end 2026.

Risks

• Growth depends on new ground leases — Inability to negotiate attractive ground leases with airport authorities or competition from other ground lessors could impede growth.
• Construction and development risks — Delays or cost overruns in constructing new campuses, such as ADS Phase 2 and BDL, could impact financial performance.
• Hangar supply and demand imbalance — If the business aircraft fleet growth or hangar demand slows, the company may not achieve expected occupancy or rental rates.
• Heavy debt and leverage — Significant indebtedness, including bonds payable and loans, could strain cash flows and limit financial flexibility.

Outlook

Management reaffirmed guidance for year-end 2026. ADS Phase 2 is expected to be completed by year-end, and BDL is expected to be completed by December 2026. The company expects continued revenue growth from existing and new campuses, with higher-than-forecast revenue per square foot at stabilized properties.
