The Bottom Line from the Web

The single most important external signal the filings cannot show is timing slippage on the entire investment story: Absolics glass-substrate mass production has now slid from a 2022-promise of "2024" to a year-end-2026 target with no named hyperscaler customer disclosed, while the 250kt copper-foil "global No. 1 by 2025" plan never materialised. Yet the company is simultaneously running a ₩1 trillion June-2026 rights offering (~60% earmarked for Absolics) into a depressed share price — a dilution that consensus rates Underperform / Neutral with target ₩102k–112k versus spot ₩159,900. The bull-bear pivot for 2026 is the Q1 EBITDA inflection (first positive in 10 quarters) versus a Korean PTAB ruling in February 2026 that tilted the Solus copper-foil patent dispute against SK Nexilis.

What Matters Most

1. ₩1 trillion rights offering closing June 8, 2026 — ~60% directed to Absolics

SKC announced on Feb 26, 2026 a ~₩1.0T rights issue, with roughly ₩590B going to glass-substrate subsidiary Absolics and the balance to debt reduction; SK Inc. (40.6% holder) supports the issue and the new listing date is June 8, 2026 (TradingView ticker 0117901G). Independent analyst Douglas Kim modelled ~22% dilution at pre-Feb prices. This is by far the most material near-term capital event and explains the simultaneous CEO turnover.

2. CEO Kim Jong-woo replaces Park Won-cheol (March 26, 2026) — also takes SK Nexilis CEO seat

The 53rd AGM appointed Kim Jong-woo (ex-Intel and SK hynix engineer/strategist) as CEO under a "Stability, Recovery and Growth" mandate. Kim concurrently runs SK Nexilis; new CFO Park Dong-ju (ex-SK Inc. portfolio planning) is also dual-hatted as Nexilis CFO. Parent SK Inc. is visibly retaking financial control as the rights offering lands.

3. Glass-substrate mass production slips again — to year-end 2026

TrendForce (May 8, 2026) reports SKC is "speeding glass substrate mass production by year-end" — confirming the original 2022 promise of "mass production 2024" has slipped first to 2H-2025 and now to late-2026. Q3-2025 SKC release said "samples enter customer qualification process" and Phase-1 build at Covington, Georgia continues. Absolics has no publicly named hyperscaler customer (NVIDIA / AMD / Google) as of May 2026, though The Elec said in late 2025 Absolics is "close to AMD approval" and Chey Tae-won publicly suggested NVIDIA interest at CES 2025.

4. FY2025 reset — ₩305B operating loss, ₩316.6B Q4 impairment, ₩893.3B liquidity raise

Per SKC's Feb 5, 2026 release, FY2025 consolidated revenue was ₩1.84T with an operating loss of ₩305B; Q4 booked ₩316.6B in one-off impairments of tangible assets in the secondary-battery and chemical businesses. To shore up liquidity SKC raised ₩893.3B in 2025 via perpetual exchangeable bonds and asset securitisations of non-core businesses — a stress signal that pre-staged the 2026 rights issue.

5. Q1 2026 inflection — EBITDA positive for the first time in 10 quarters

April 27, 2026 release: revenue +13.4% YoY to ₩496.6B, operating loss narrowed to ₩28.7B, EBITDA turned positive at ₩10B and EPS beat consensus by 17.5%. Per the Q1 IR PDF, Q1 ESS-grade copper-foil sales volume rose +132% QoQ and +390% YoY; North-America-bound copper-foil volume +95% QoQ and +403% YoY. The technical setup matches: stock +35.5% YTD into May 8, 2026 close.

6. Solus Advanced Materials patent appeal upheld against SK Nexilis (Feb 2026)

Korea's IP Trial and Appeal Board upheld Solus Advanced Materials' copper-foil patent in February 2026, "tilting the dispute against SK Nexilis." The U.S. PTAB denied SK Nexilis's IPR institution; the parallel E.D. Texas trade-secret case (2:23-cv-00539) advances. This is a material overhang on copper-foil segment value not flagged in standard sell-side research.

7. Cathode investment plan cancelled (Dec 31, 2025) — strategic retreat

SKC formally cancelled a planned battery-cathode investment programme on the last trading day of 2025 — a notable retreat from earlier secondary-battery materials expansion ambitions and a precursor to the 2026 portfolio reorganisation around Absolics. Combined with the cancelled silicon-anode/Nexeon hand-off, the 2021 ambition of becoming "global No. 1 in copper foil by 2025 with 250kt output" has been quietly retired.

8. Consensus is Neutral with target ~₩102k–112k vs ~₩159,900 spot — implying ~30% downside

Stockopedia consensus target ₩112,822; Investing.com average ₩104,778; Yahoo: low ₩72,000 / avg ₩106,419 / high ₩140,000. Rating mix: 2 Buy / 5 Sell / 3 Hold from 10 actively-rating analysts of 25 covering. Nomura downgraded to Reduce on Apr 4, 2025, slashing target to ₩90,000 from ₩150,000. The street has not yet caught up to the Q1 inflection.

9. Absolics secured CHIPS Act $75M for Covington, GA glass-substrate facility

US Commerce Department awarded Absolics $75M in CHIPS-Act funding (May 29, 2024 announcement; first-phase released May 14, 2025) to support a 120,000-sq-ft glass-substrate plant backing ~$300M total Absolics investment. This is the only direct US-government endorsement of SKC's glass-substrate platform and an asymmetric upside if customer qualification lands.

10. Historic governance flag — Cho Dae-sik indictment (May 25, 2021) over SKC capital injections into SK Telesys

SK Group's #2 executive Cho Dae-sik (Chairman of SK Supex Council and former Chairman of SKC's BoD) was indicted for breach of trust over SKC's ₩70B (2015) and ₩19.9B (2012) capital injections into capital-eroded affiliate SK Telesys. Prosecutors said SKC "appeared to have skipped appropriate investment reviews ahead of its SK Telesys deals." Co-defendants included an ex-SKC senior exec and SK Telesys CEO (accounting fraud — inflated assets ₩15.2B). SK Chairman Chey Tae-won was an unindicted co-conspirator.

Industry Context

Copper foil price softness offsets volume gains

Two contradictions matter for the 2026 thesis. First, management talks "operational efficiency from full-scale Malaysia plant" and ~50% YoY secondary-battery sales growth, but Chinese copper-foil prices for lithium batteries softened into Feb 2026 with "intensified market divergence." Margin gains from utilisation may not flow through to the P&L if processing fees keep falling. Source: copperexpo.com.cn (Feb 2026).

Glass substrate — competitive window narrows in 2027

Samsung Electro-Mechanics publicly targets the $12B glass-substrate market with a 2027 ramp and is "in talks with Big Tech for supply" (Nov 2025). Intel licensing glass-substrate tech (TrendForce, Aug 2025) widens the field. Absolics's "world's first commercial" claim has a ~12-18 month window before Samsung enters with chaebol-scale capex behind it.

Semiconductor materials — a real bright spot

SKC's semiconductor materials segment hit highest-ever annual performance in 2025 from AI data-centre demand; high-growth products (CMP pads, etc.) jumped from 21% (2021) to 36% of semi-segment sales by 2025. ISC test-socket business benefits from a 7% CAGR market reaching $1.83B by 2030. Combined with Absolics, the semi-materials pillar is the highest-conviction part of the 2026 story.

Strategic portfolio rotation summary

Out: PET film business sold to Hahn & Co (₩1.6T, 2022); fine ceramics to Hahn & Co (₩360B, Feb 2024 — renamed Solmics); battery cathode plan cancelled (Dec 2025); silicon-anode role handed off to Nexeon (Dec 2025).

In: KCFT/SK Nexilis copper foil (₩1.19T, 2019/2020); 45% of ISC test sockets (₩522.5B, Jul 2023); Absolics glass substrate (multi-tranche capex, ~$300M total + ₩590B from 2026 rights raise); 17.23% of Ecovance (₩40B, Dec 2025).

The portfolio rotation is real and visible. Whether it creates value depends on execution at Absolics in the next 12-18 months and whether the copper-foil cycle stops eating equity.
