Stormtec스톰테크

Stormtec remains profitable with steady margins, but revenue growth has slowed and the shares trade near the lower part of their 52-week range.

Stormtec makes water purifier components and printed circuit boards, with major customers including LG Electronics and Coway. Trailing twelve-month revenue is about ₩71.5B with an operating margin of 18% and a net margin of 15.3%, as of H1 2026. The share price of ₩3,645 sits between its 52-week low of ₩3,330 and high of ₩4,200.

What stands out

• Revenue grew 4.1% in 2025 after 21.3% growth in 2024, so top-line momentum has cooled.
• Operating margin has eased from 21.1% in 2023 to 17.1% in 2025, with trailing figures at 18%.
• Net income of ₩14.4B in 2024 fell to ₩10.2B in 2025, while trailing net income is ₩11.0B.
• Valuation metrics are low: P/E about 8.9, P/B about 1.1, and a dividend yield of 12.3%, though the data does not explain the dividend's sustainability.
• Borrowings of ₩28.8B exceed cash of ₩10.6B, and the liabilities-to-equity ratio is 45.2%.

What to watch

• The half-year and quarterly results cadence, and whether revenue growth picks up from the slow 2025 pace.
• The new facility investment filed on 2026-09-28 and how it is funded given the borrowings level.
• Foreign ownership is only 1.8% and fell slightly over 60 days, so investor flow trends and the cash dividend timing from the filings are worth monitoring. No recent news headlines were available in the data.
