Lumir루미르

Lumir reports widening losses and a steep share price fall over the past year, despite a recent government-linked selection.

Lumir, a Korean space and shipbuilding technology company listed on KOSDAQ, posted trailing twelve-month revenue of ₩13.3B with an operating loss of ₩1.4B to H1 2026, after a small net profit in 2025 and a larger loss in 2024. The shares closed at ₩5,040 on 2026-10-28, down 44.1% over one year and 28.7% over one month, with a market capitalisation of about ₩89.8B. The company is building its LumirX small SAR satellite constellation, with services expected after launches starting in 2026.

What stands out

• Trailing twelve-month operating margin is -10.5% and net margin is -7.3%, so the business is still loss-making at the operating level.
• Revenue fell 26% in 2025 to ₩10.6B, though the company reported a small net profit of ₩46M that year after an operating loss of ₩594M.
• The balance sheet shows cash of ₩23.7B against borrowings of ₩8.4B, and liabilities at 15% of equity; trailing free cash flow is ₩2.2B.
• Foreign ownership fell from 4.5% to 3.7% over about 60 days, and 20-day flows show net selling by foreign and institutional investors with net buying by retail investors.
• The most recent headline reports Lumir was selected as a recommended item in three satellite core equipment categories for industrial cooperation offset trade.

What to watch

• The half-year report for June 2026 and the upcoming full-year results, to see whether losses narrow as revenue and launch-related work progress.
• Filings on new facility investment, which have been corrected several times since August 2026, and the terms and dilution effects of the convertible bond issues made in 2026.
• Timing of the first LumirX launches, since the company says its data services depend on them starting in 2026.
