Caelum케일럼

Caelum is loss-making on a trailing basis but near breakeven in H1 2026, after a weak 2025 and a sharp share price fall over the past year.

Caelum runs three businesses: geothermal and process equipment, children's and senior phones, and aircraft engine parts. Trailing results through H1 2026 show revenue of about ₩73.7B with a small operating loss of about ₩0.3B and a small net profit of about ₩0.6B. The shares closed at ₩1,111 on 2026-10-19, down 38.7% over one year and well below the 52-week high of ₩1,944.

What stands out

• Trailing revenue is about ₩73.7B, with operating margin of -0.4% and net margin of 0.8%, so profitability is thin.
• Full-year 2025 showed revenue down 16.1% to about ₩81.7B and a net loss of about ₩2.5B, following a profitable 2024.
• Cash of about ₩6.9B is above borrowings of about ₩5.2B, and trailing free cash flow is about ₩6.3B, though the data does not explain what drove it.
• Valuation shows a trailing P/E of 73.3 and P/B of 0.8, while the data includes no fair value model or analyst targets.
• Recent filings are mostly routine: amended half-year and contract reports, insider and 5%+ holding reports, and a merger completion in March 2026. News headlines were not provided.

What to watch

• The next quarterly or annual results, and whether operating profit stays positive after the H1 2026 amendment.
• Amendments to the major sales or supply contracts filed in May and June 2026, since the data does not give contract details.
• Foreign ownership, which slipped from 1.4% to 1.3% over 60 days, and the 20-day foreign net selling of about ₩45M.
