Amend: Daegu court stays 3-mo public-sector bid ban until 17 Nov · ban hit ~93.9% of 2025 sales

Wed 28 Oct 07:46 KST (pre-open): Woojin Ntec amends its 8 Oct public-sector bid-ban filing after Daegu court provisionally stays the 3-month ban through 17 Nov — the banned customer class was ₩42.1bn / 93.9% of 2025 sales (3-mo simple ₩10.5bn = 23.5% sales). UP: interim stay restores new-bid access into mid-Nov and softens an existential new-work overhang on a thin ~₩77bn nuclear/thermal O&M name (existing contracts were never cut). 3-8%: relief is real on a sold-down micro/small-cap, but stay is provisional not a final cancel (refuse 8%+ win-frame and 1-3% under-size). p≈35%: ~73 min into 09:00 auction is a real pre-open leftover clock; Oct 8 ban already crushed the tape so open gap is residual stay-credit, not first print of the ban.

Why direction: Court provisional stay of a 3-mo public-sector bid ban that covered ~94% of sales → UP relief vs ban overhang, not MIXED process noise. · Why magnitude: Existential new-bid overhang on ~₩77bn KOSDAQ softens, but stay expires/is provisional → UP 3-8%; refuse 8%+ final-win and 1-3% under-size. · Why probability: Pre-open ~07:46 into 09:00 auction (~73 min) → ~35% unused leftover; ban pain already in the tape since 8 Oct.

Wed 28 Oct 07:35 KST (pre-open fair disclosure): PI Advanced Materials prints 3Q sales ₩55.5bn (−28.3% QoQ / −18.8% YoY) and OP ₩12.5bn (−45.5% QoQ) while YoY OP still +7.9% and 9M OP ₩49.6bn (+36.1% YoY) — two-way earnings on a ~₩491bn PI-film KOSPI name. MIXED: sequential sales/OP cliff is real; YoY OP and 9M still-green book refuse a clean DOWN dump (LG Innotek / Hanwha Systems two-way class). 1-3%: mid-cap band compression; sales%≠band and refuse 3-8%/8%+ off the QoQ OP % alone. p≈30%: ~85 min into 09:00 auction is a usable pre-open leftover clock on a liquid-enough name; Tue already +5.9% so open may gap on the QoQ fade rather than chase Tuesday’s bounce.

Why direction: QoQ sales/OP cliff vs still-green YoY OP and +36% 9M OP → MIXED two-way, not clean UP or DOWN. · Why magnitude: ~₩491bn KOSPI mid-cap → MIXED 1-3% band compression; refuse higher bands off QoQ OP % (sales%≠band). · Why probability: Pre-open ~07:35 into 09:00 (~85 min) → ~30% unused leftover; Tue already +5.9% is a partial tape vote into the print.
