Isaac Engineering이삭엔지니어링

Isaac Engineering remains loss-making on a trailing basis, though its share price has fallen sharply over the past year and its balance sheet carries significant debt.

The company supplies factory automation and smart factory solutions, mostly to Korean manufacturers. Trailing twelve-month revenue to H1 2026 was ₩77.0B, with an operating loss of ₩7.3B and a net loss of ₩9.0B. The share price closed at ₩3,080 on 2026-10-28, down 62.3% over one year, and the data shows a price-to-book ratio of 0.9 but no earnings-based valuation.

What stands out

• Trailing operating margin is -9.5% and net margin is -11.7%, with losses in each of 2021, 2024, and 2025 in the annual figures; 2022 was the only profitable year shown.
• Revenue rose 15.4% in 2025 to ₩79.0B after a 31.9% drop in 2024, so top-line results have been volatile.
• Borrowings of ₩18.9B exceed cash of ₩10.0B, and liabilities are 172% of equity; free cash flow was negative at -₩0.8B.
• Foreign ownership fell from 4.4% to 3.5% over about 60 days, and 20-day investor flows were net negative across foreign and retail investors.
• Filings in the period were mainly 5%+ holding reports, plus the half-year report for June 2026; no news headlines were in the data.

What to watch

• The next periodic results and whether operating losses narrow from the H1 2026 trailing levels.
• Further 5%+ holding reports or insider shareholding filings, which could signal changes in major shareholdings.
• Debt levels and cash generation, given borrowings above cash and negative free cash flow; the data does not include any guidance or outlook.
