Share count rising — dilution

+127.4% over 4y

The company has issued more shares over this period, which dilutes each existing shareholder’s stake.

Diluted shares outstanding: 15.0M (2021) → 34.0M (2025)

Sky Harbour Group builds and leases private aviation campuses at airports across the United States. These campuses are called "home bases" and are designed specifically for private jet owners who want a dedicated, secure place to store and service their aircraft. The company targets high-net-worth individuals and corporate flight departments that own or operate business jets.

Sky Harbour makes money by charging long-term leases to private jet operators who rent hangar space at its facilities. The company is still in an early growth phase, operating at a significant operating loss as it builds out new locations. Its competitive edge comes from offering premium, purpose-built hangar campuses rather than the older, shared facilities found at most airports — a model that is hard to replicate quickly due to the difficulty of securing airport land leases. The key risk is that building new campuses requires heavy upfront capital, and the company must fill enough hangar space at each location to eventually turn a profit.

Strong grower

Sky Harbour Group is growing revenue at 56% year-over-year. The Winston Score penalises unprofitable companies, but revenue at this pace tells a different story — this is a company still in "build mode."

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
