Yest's trailing earnings have recovered to a small profit after a loss-making 2025, but the shares trade at a high P/E and have fallen over the past month.

Yest makes heat and pressure process equipment for semiconductor and display factories. Trailing twelve-month revenue to H1 2026 is ₩107.7B with operating income of ₩6.4B and net income of ₩6.3B, after 2025 revenue fell 13% to ₩87.1B and posted a small net loss. The share price is ₩24,600, down 13.2% over one month, though up 30.2% over one year.

What stands out

• Trailing operating margin is 5.9% and net margin 5.8%, well below the 11.3% operating margin reported for 2024.
• Valuation is stretched on trailing numbers: P/E is 85 and P/B is 3.7, with no dividend paid.
• Trailing free cash flow of about ₩4.4B and cash of about ₩25.1B are reported, and no borrowings are listed in the data.
• Filings include several major sales or supply contracts in July and August 2026, plus an amended contract filing, but the data does not give their values.
• The one news headline in the data points to uncertainty over the lifting of a patent lawsuit, alongside growth signals.

What to watch

• The next periodic results and whether margins hold near the trailing levels after the 2025 loss.
• Outcome of the patent lawsuit uncertainty mentioned in the news headline; the data gives no details.
• Insider shareholding reports and any further contract filings, since the data does not show foreign ownership or investor flows.
