Sawnics쏘닉스

Sawnics is still loss-making on a trailing basis, though its shares have risen sharply over the past year.

Sawnics, a Seoul-listed maker of RF filters for mobile devices, reported trailing twelve-month revenue of ₩19.4B to H1 2026 but an operating loss of ₩6.7B and a net loss of ₩5.5B. The share price closed at ₩3,840 on 2026-10-16, up 73.8% over one year, and sits well below its 52-week high of ₩8,640.

What stands out

• Revenue rose from ₩13.8B in 2023 to ₩18.2B in 2025, but operating losses have persisted in every year shown, with a 2025 operating margin of -36.6%.
• Net loss widened to ₩6.9B in 2025 from ₩2.2B in 2024, and trailing free cash flow was negative at about ₩4.6B.
• Cash of ₩10.8B exceeds borrowings of ₩5.3B, and the liabilities-to-equity ratio is 52%.
• The company pays no dividend, and the data has no price-to-earnings ratio because earnings are negative; price-to-book is 2.0.
• Foreign ownership eased slightly to 20.8% from 21.5% over the past 60 days, and 20-day flows were net negative for foreign investors.
• Recent filings are mainly routine: half-year and quarterly reports, shareholder holding reports and investor relations events. No recent news headlines were available in the data.

What to watch

• Next quarterly and annual filings, to see whether operating losses narrow from the trailing level.
• Free cash flow and the company's cash balance relative to its borrowings, given the negative trailing cash flow.
• The profile names reliance on a limited set of fabless customers in the US and Greater China; the data does not give customer concentration figures.
