Isupetasys이수페타시스

Isupetasys is highly profitable on trailing numbers, but its share price has fallen sharply over the past month and trades well below its 52-week high.

The printed circuit board maker reported trailing twelve-month revenue of ₩1.31T and operating income of ₩259B to H1 2026, with a 19.7% operating margin. Its shares closed at ₩83,500 on 2026-10-26, down 29.8% over one month but only 10.8% over one year. Free cash flow over the same period was negative at ₩-112B, and borrowings of ₩283B exceed cash of ₩144B.

What stands out

• Revenue grew 30% in 2025 to ₩1.09T, and operating margin rose to 18.8% from 12.2% in 2024.
• Trailing free cash flow is negative at ₩-112B, so reported profits are not yet turning into cash in this period.
• The DCF fair value model gives a base of ₩31,438, bear ₩20,313 and bull ₩48,557, all well below the current price; the model's basis and inputs are not detailed in the data.
• Foreign ownership edged up to 17.4% from 17.1% over 60 days, while institutions sold about ₩143B over the last 20 days and foreign investors bought about ₩125B.
• The only recent headline in the data says profitability improved on expansion of high-spec products; no company guidance is included.

What to watch

• The next half-year or annual results and whether free cash flow turns positive as borrowings stay high.
• Continued insider shareholding and 5%+ holding filings, which have been frequent in recent weeks.
• Valuation risk: the P/E of 30.5 compares with peers ranging from 13.1 to 82.9, and the share price is about 49% below its 52-week high of ₩164,400.
