SemiFive세미파이브

SemiFive, a custom chip design services firm listed in late 2025, is posting large operating losses and its shares have fallen sharply from their 52-week high.

SemiFive provides end-to-end design engineering for custom system semiconductors, serving AI chip startups, established fabless firms and OEMs. For the trailing twelve months to H1 2026 it reported revenue of ₩121B, an operating loss of ₩53B and a net loss of ₩56B, with a negative free cash flow of ₩11B. The stock closed at ₩13,880 on 2026-10-23, roughly 73% below its 52-week high of ₩51,300 and close to its 52-week low of ₩12,630.

What stands out

• Operating margin is -44.1% and net margin is -46.5% on trailing revenue of ₩121B, so losses are large relative to sales.
• Cash of ₩32B is held against liabilities equal to 56.5% of equity; the data does not show any borrowings figure.
• Trailing free cash flow was -₩11B, and the valuation shows P/B of 2.1 and P/S of 3.9 with no meaningful P/E because earnings are negative.
• Over the last month the share price fell 14.4% and over three months 16.6%; the one-year return is not available because of the short trading history.
• Foreign ownership dropped from 5.5% to 4.6% over about 60 days, while 20-day flows show institutions and foreigners net selling and retail net buying.
• Recent filings are mostly amended and routine insider shareholding reports; no news headlines were available in the data.

What to watch

• Next periodic results and whether operating losses narrow from the trailing H1 2026 level.
• Further insider shareholding filings and any changes in institutional or foreign holdings.
• Cash burn: the data shows cash of ₩32B against negative free cash flow, so future funding needs are worth tracking; the data does not include any guidance or analyst forecasts.
