Permanent float shrink of ~3.2% of OS (book ₩15.9bn; ~₩9.0bn / ~3.2% of ~₩280bn mcap at ₩23,150) from already-held treasury — cancel-bound UP mechanics, not a new open-market bid.

Top-line still grows (+19.5% YoY) but the quarter flips to an operating loss and a deep pretax/NI hole (−₩46.6bn / −₩36.7bn) — much wider than last year’s soft Q3. DOWN on earnings quality: revenue did not drop through to profit, and the pretax gap vs OP points to a large non-operating hit on top of the OP loss-turn. Band 3–8% because the pretax hole is ~₩47bn on a ~₩144bn mcap name (~33% of mcap) — refuse 8%+ on liquid KOSPI steel/CM beta and because the YoY base was already a small loss (not a first-time black-to-red shock).
