Clean & Science크린앤사이언스

Clean & Science remains loss-making on a trailing basis, though its share price has risen over three months and its balance sheet carries heavy borrowings.

Clean & Science, a KOSDAQ-listed filtration maker, reported trailing revenue of about ₩84.8B for the period to H1 2026 but an operating loss of about ₩2.0B. Debt is high relative to equity at about 308% liabilities to equity, with borrowings of ₩39.1B against cash of ₩3.9B. The share price closed at ₩3,200 on 2026-10-22, within a 52-week range of ₩2,110 to ₩4,740.

What stands out

• Revenue has been broadly flat over recent years, from ₩86.0B in 2022 to ₩86.1B in 2025, after a dip in 2022 and a rise in 2023.
• The company has posted operating losses in four of the last five years, with 2023 the only year of operating profit shown.
• Trailing free cash flow is positive at about ₩5.6B, even though net income is negative.
• The filings list several insider shareholding reports and a treasury stock acquisition with results reported on 2026-09-28, but the data does not explain the purpose of the buyback.
• Foreign ownership fell from 3.7% to 3.2% over about 60 days, and 20-day investor flows show net selling by foreign and retail investors.

What to watch

• Next periodic results and whether operating losses narrow from the trailing figures shown.
• Progress on the share buyback and any further filings on executive or major shareholder trading plans.
• Debt levels and interest costs given borrowings of about ₩39.1B against limited cash; the data does not include interest expense or refinancing terms.
