Bull & Bear

Bull and Bear

Verdict: Watchlist — the SOTP works on paper, but the two load-bearing claims (1Q26 was a structural inflection, and ISC's 95× P/E holds) both resolve inside one earnings cycle, and the price has already run +75% in six weeks at 10-year-extreme volatility. Bull and Bear agree on the same balance sheet, the same ISC mark, and the same 1Q26 P&L; they disagree on whether the inflection is real and whether ISC's multiple is durable. The decisive tension is whether 2Q26 EBITDA stays positive without the Mid-East PG-spread tailwind — that single print resolves more of the debate than any other variable. Owning the stock today is paying for confirmation that has not yet been delivered into a tape that has already priced most of it. Wait for the 2Q26 print (mid-August 2026) and the post-rights cap structure to clear, then re-underwrite.

Bull Case

Bull's price target: ₩220,000 over 12–15 months (through Q2 2027 earnings). Method is sum-of-parts: ISC parent share at LEENO premium for sustained AI demand (~₩3.0T), SK nexilis at through-cycle replacement value with FEOC-driven NA volume (~₩900B), SK picglobal at trough peer multiple post-1Q26 (~₩500B), Absolics option re-rated to ~₩600B on visible 1H27 hyperscaler qualification, plus ₩1T rights cash, less ~₩2T allocated parent net debt ≈ ~₩4T equity across ~46M post-rights shares ≈ ₩87,000 floor; bull-case re-rating drives the ₩200–240K upper-bound zone (also the prior 2021 ATH range). Primary catalyst is the 2Q26 print in mid-August 2026 — a second consecutive positive consolidated EBITDA quarter that confirms 1Q26 was structural. Disconfirming signal: 2Q26 EBITDA reverts negative AND ISC standalone compresses ≥20% from ₩5.37T — the conjunction breaks the SOTP and the cycle leg simultaneously.

Bear Case

Bear's downside target: ₩95,000 (−41% from ₩159,900) over 12–15 months. Method stacks three compressions: (a) mechanical ~22% dilution from June rights takes ₩159,900 to ~₩125,000 holding EV constant, (b) ISC multiple compression from 95× P/E toward LEENO's 39× EV/EBITDA cuts SKC's ISC stake from ~₩2.42T toward ~₩1.3T (~₩25K/share), (c) chemical PG tailwind reverts and Malaysia copper-foil EBITDA-positive proves a one-quarter event. Lands ₩90–100K, between Nomura's ₩90,000 and consensus ₩105,864; anchor at ₩95,000. Primary trigger is the June 8 rights listing crystallizing dilution arithmetic, followed by 2Q26 if chemical OP reverts and EBITDA prints negative again. Cover signal: a named hyperscaler qualification at Absolics (NVIDIA / Google / Broadcom / Samsung) that re-rates the glass-substrate option from ₩0–200B to ₩1T+; or two consecutive quarters of consolidated EBITDA > +₩30B with ISC HBM mix still rising (softer secondary).

The Real Debate

Verdict

Watchlist. Bear carries marginally more weight today because two of the three bear points (the ₩594B unexplained below-the-line wedge widening every year, and the 117% realized-vol blow-off into uniformly negative sell-side coverage) are observed facts that do not depend on a future event, while the strongest bull points (1Q26 inflection, capital reset clearing) require the 2Q26 print to confirm. The single most decisive tension is whether 1Q26 was a structural three-engine inflection or a Q4-big-bath / Mid-East-PG artifact — and that resolves on one earnings date in mid-August 2026, six weeks after the rights listing has cleared the dilution arithmetic. The bull case could still hold: the ISC mark is real, listed, and AI-leveraged, and a positive 2Q26 paired with an Absolics named-hyperscaler announcement could re-rate the SOTP fast enough that early entry would pay. The condition that would shift this to Lean Long is a 2Q26 consolidated EBITDA print > +₩20B with chemical OP still positive, accompanied by post-listing tape absorption that does not give back the rights-offering discount within four weeks. The condition that would shift it to Avoid is a 2Q26 EBITDA reversion to negative paired with any ISC standalone compression ≥15% — which would break both the cycle and the SOTP legs at once.
