The same analysis cites a high price-to-earnings ratio of 108.5, while also observing the stock’s relatively low P/E when measured against near-term earnings growth expectations.

Sky Harbour’s recent operating results and analyst commentary are mixed. For the full year 2025, the company reported revenue of $27.5 million, an increase of 87% year-over-year. Despite that top-line expansion, the company has recorded rising operating expenses and continues to report losses, contributing to negative EPS forecasts for upcoming quarters. Adjusted EBITDA for the fourth quarter of 2025 was reported at negative $1.0 million, a figure that corresponded with one firm’s estimate and exceeded consensus expectations by $0.7 million.
Among the analyst actions disclosed, BTIG reaffirmed a Buy rating on Sky Harbour and maintained a price target of $13.00 following the company’s fourth-quarter results. The mix of rapid revenue growth, widening expenses and persistent losses frames the current investor debate around valuation and near-term profitability.
This Form 4 filing documents the insider sale and the continuing equity and warrant positions held by Boston Omaha, while recent reporting on Sky Harbour’s financials underscores both growth in revenue and ongoing cost and profitability challenges.
