Korea Airport Service: Profits Recovered Since 2022 and Shares Trade at Low Multiples, but Model Estimate Is Far Above Price
Why this report
Start of coverage: written when a reader opened this company and there was no report yet.
Korea Airport Service closed at ₩88,000 on 2026-10-19, up 39.7% over one year, with trailing revenue of ₩697.9B and an operating margin of 7.7%. Its multiples are low (P/E 6.1, P/B 0.7), and a model estimate sits well above the share price, though the range is very wide.

Thesis
The data supports a clear earnings recovery. Operating income moved from a loss of ₩0.9B in 2021 to ₩47.0B in 2025 and ₩53.6B on a trailing basis to H1 2026. Return on equity is 11.5% and leverage is modest, with liabilities at 34.9% of equity.
The shares have risen 10.3% in one month and sit below the 52-week high of ₩102,600. Foreign ownership rose from 11.7% to 13.6% over 60 days, while retail investors were net sellers over the past 20 days. Short balance is just 0.1%.
What the data does not show: the drivers of revenue growth, guidance, or why revenue growth slowed from 36.0% in 2023 to 5.9% in 2025. The recent news headlines concern Korea Airports Corporation, a different entity, and say nothing about this company's results.
