EO Technics이오테크닉스

EO Technics has strong recent profitability, but its shares have fallen about 21% over the past month and trade at a high valuation.

EO Technics makes laser-based equipment for semiconductor, PCB, display and mobile phone makers, with about half of sales exported. Trailing results to H1 2026 show revenue of ₩444.7B, an operating margin of 24.6% and net income of ₩108.5B, well above 2025 levels. The share price of ₩379,000 sits well below its 52-week high of ₩623,000, but still implies a P/E of about 43.

What stands out

• Revenue rose 18.7% in 2025 to ₩380.9B, and trailing revenue to H1 2026 reached ₩444.7B.
• Operating margin improved from 9.7% in 2024 to 21.2% in 2025, and 24.6% on a trailing basis.
• Cash of ₩233.1B against borrowings of ₩7.0B, with trailing free cash flow of ₩74.9B.
• The company pays no dividend (0% yield), and the filings list a corporate value-up plan dated 1 April 2026.
• The in-house DCF model gives a base value of ₩75,987, but the share price is far above that figure; the model is a company-prepared estimate, not a forecast.

What to watch

• Next quarterly and annual results, to see whether margins hold after the strong trailing period.
• Foreign ownership fell from 30.3% to 26.8% over 60 days, and the recent 20-day flows are mixed across investor groups.
• Valuation risk: P/B of 6.2 and peer multiples vary widely, and the data includes no news headlines to explain recent share moves.
