HiDeep하이딥

HiDeep's revenue has collapsed for three years and it is running heavy losses, with the share price down about 72% over the past year.

HiDeep is a small fabless chip designer for touch and stylus products. Trailing twelve-month revenue to H1 2026 was about ₩0.5B against an operating loss of about ₩13.0B, and free cash flow was roughly -₩10.3B. Cash of about ₩3.5B and no reported borrowings sit against that burn, and the data does not state how the company plans to fund the gap.

What stands out

• Revenue fell from about ₩18.1B in 2022 to about ₩1.8B in 2025, and TTM revenue to H1 2026 is about ₩0.5B.
• Operating losses have stayed large every year shown, with TTM operating income at about -₩13.0B and net income at about -₩17.0B.
• Liabilities are about 4.3 times equity, and the data reports no borrowings, so the leverage figure reflects other liabilities.
• The stock closed at ₩1,418 with a market cap of about ₩26.1B, versus a 52-week high of about ₩8,400; the 1-year return is -71.9%.
• Foreign ownership fell from 3.7% to 0% over 60 days, and the 20-day flows show foreign selling against retail buying.
• Recent filings include a trading halt on 2026-09-15, a 5%+ holding report, insider shareholding reports and stock option grant amendments, all on or around 2026-09-10 to 15. The data does not say why the halt occurred.

What to watch

• The reason for the 2026-09-15 trading halt and whether trading has resumed, which is not in the data.
• Whether revenue stabilises and the cash balance of about ₩3.5B can cover the ongoing negative free cash flow.
• The model's fair value estimates of ₩131 to ₩150 sit well below the current ₩1,418 price; the data gives no further detail on how these were set.
