Iste, a KOSDAQ-listed maker of semiconductor equipment such as FOUP cleaners and sorters, reported trailing revenue of ₩41.8B and an operating loss of ₩2.6B for the twelve months to H1 2026.

• Trailing net loss is ₩1.8B with a net margin of -4.3%, and ROE is -11%.
• Borrowings are ₩26.2B against cash of ₩3.6B, and liabilities are 152.1% of equity.
• Trailing free cash flow is positive at ₩156M, but it is small relative to the debt load.
• Several major sales or supply contract filings appeared in September and October 2026, but their terms are not in the data.

What to watch

• The next full-year or quarterly results, to see whether revenue recovers and losses narrow.
• Details of the recent supply contracts and whether they convert into revenue.
• Debt repayment capacity and any further filings on financing, given the gap between borrowings and cash.
