Fine Semitech에프에스티

Fine Semitech returned to a small operating profit on a trailing basis, but a large net loss and heavy borrowing keep the picture fragile.

Fine Semitech makes pellicles that protect photomasks in chip and display manufacturing, plus chillers and process equipment. Trailing revenue to H1 2026 was about ₩294.6B with a small ₩6.0B operating profit, yet net income was a loss of about ₩4.6B. The share price has fallen sharply over the past year, to ₩24,450 from a 52-week high of ₩51,000.

What stands out

• Trailing operating margin is 2.0%, up from a loss in 2025 and 2023, but net margin is -1.6%, so below-operating costs or other items pushed the bottom line into loss.
• Borrowings are about ₩112.9B against cash of about ₩20.2B, and liabilities are 111.6% of equity; trailing free cash flow is negative at about -₩63.9B.
• Revenue grew 18.1% in 2025 and 20.1% in 2024, yet 2025 still posted a net loss of about ₩12.3B after a prior-year profit.
• Valuation data shows price-to-book of 2.0 and price-to-sales of 1.8, with no meaningful earnings-based P/E because of losses and no dividend.
• Filings in late September and early October 2026 include a treasury share sale decision and results, a change of largest shareholder, and several 5%+ holding and insider reports.
• Over 20 trading days, institutions were net buyers (about ₩8.0B) while retail investors were net sellers (about -₩7.0B) and foreign flows were roughly flat; foreign ownership fell from 9.0% to 7.6%.

What to watch

• Upcoming results and whether operating profit translates into net profit, given the gap between trailing operating and net figures.
• Debt levels and negative free cash flow, which bear on funding needs, plus any further treasury share or shareholder-change filings.
• The data contains no news headlines, analyst forecasts or fair value estimate, so the outlook beyond the filings is not covered here.
