EcoSimplex에코심플렉스

EcoSimplex remains loss-making on a trailing basis, though its shares have rebounded over the past three months after a steep one-year fall.

The company, listed on KOSDAQ, reports trailing twelve-month revenue of ₩14.8B with an operating loss of ₩3.3B and a net loss of ₩0.4B through H1 2026. Its profile describes waste-to-energy operations, including biogas power and hydrogen plans, alongside newer AI businesses. The share price is ₩2,105, with a market value of about ₩29.5B, well below its 52-week high of ₩4,435.

What stands out

• Revenue has declined from ₩18.0B in 2024 to ₩17.2B in 2025, and trailing revenue is ₩14.8B, so the top line is shrinking.
• Operating losses have been reported in most recent years, with a trailing operating margin of -22%, though the trailing net loss is much smaller than the operating loss.
• Free cash flow is reported at about -₩4.8B on a trailing basis, and cash of ₩2.4B is held with no borrowings listed.
• The price-to-book ratio is 0.4 and the company pays no dividend; price-to-earnings is not meaningful because earnings are negative.
• Foreign ownership has edged up to 2.2% from 1.9% about 60 days earlier, while retail investors were net sellers over the last 20 days, and the stock is up 8.6% over three months but down 40.5% over one year.

What to watch

• The next half-year or annual results, and whether the operating loss narrows from the trailing -22% margin.
• Progress on the hydrogen refueling and production projects and the AI businesses, which the data does not give financial detail on.
• Amended major sales or supply contract filings and recent 5%+ holding reports, which were frequent in August to October 2026; the data does not explain their content.
