Korea Market Morning Brief — Jun 26, 2026: Samsung, SK Hynix, Hyundai & More (Pre-Market)

Korea Market Morning Brief — Jun 26, 2026. A pre-market look at the ten large-caps that foreign investors watch most closely on the KOSPI. This edition is deliberately qualitative: we do not quote intraday index levels, the won/dollar rate, or specific analyst price targets, because those real-time figures cannot be sourced reliably at the time of writing. Instead we focus on verifiable company catalysts, risks and the earnings/disclosure calendar.

Korea pre-market brief — large-cap watchlist

This week's theme. The tape is being led by semiconductors and a domestic-platform rally. The standout structural story: SK Hynix has overtaken Samsung Electronics as the KOSPI's most valuable company for the first time in about 26 years, on the strength of its high-bandwidth-memory (HBM) franchise for AI. A notable twist this week: reports that SK Hynix is retooling some capacity toward highly profitable conventional DDR5 rather than rushing every line into next-gen HBM4. Separately, NAVER and Kakao have surged on bets that the new administration's AI and stablecoin agenda will favor domestic tech. Treat near-term price swings as elevated; the durable signals are the AI-memory leadership shift and the policy push behind domestic tech.

Notes are qualitative summaries of recently reported catalysts/risks, not price forecasts.

Semiconductors lead the tape

Semiconductors — Samsung, SK Hynix, Hanmi

SK Hynix (000660). The clear AI-memory winner: HBM demand from global accelerator customers has lifted it past Samsung in market value for the first time in about 26 years, making it the KOSPI's most valuable company. A fresh wrinkle this week: industry reports that SK Hynix is delaying some HBM3E-to-HBM4 line conversions and retooling that capacity for conventional DDR5, where margins are currently very high — a near-term profit optimization rather than a slowdown in AI memory. Risk: the stock has run hard, so it is sensitive to any wobble in AI-capex sentiment.

Samsung Electronics (005930). Ceded the top KOSPI cap spot but retains broad memory/foundry exposure and continues to push next-gen HBM. Full Q2 2026 results are scheduled for Jul 23, 2026 (preliminary guidance typically lands in early July; date to be confirmed). Risk: relative HBM positioning versus SK Hynix remains the key debate.

Hanmi Semiconductor (042700). A pure-play on HBM manufacturing equipment (TC bonders, HBM inspection). Concrete catalyst: SK Hynix's first order for Hanmi's TC Bonder 4.5 “Griffin,” disclosed around Jun 9, 2026 — a roughly 44.2 billion won deal qualifying Hanmi for sixth-generation thermo-compression bonding used in HBM4. It is a leveraged read on HBM capacity additions. Risk: highly cyclical and sensitive to chip-capex timing.

Autos navigate US tariffs

Autos — Hyundai, Kia

Hyundai Motor (005380). US auto tariffs remain the dominant earnings headwind, and management has been accelerating US localization — aiming to build more than 80% of US-sold vehicles in America by 2030. For 2026, Hyundai and Kia jointly target combined global sales of about 7.51 million vehicles (~3.2% growth), leaning on pricing and new models. Risk: tariff burden is expected to stay material this year.

Kia (000270). Kia is guiding to roughly 3.35 million units in 2026 with strong electrified-vehicle growth (targeting a large jump in HEV/EV volumes), and to an earnings recovery on new launches and a better mix. Risk: the same external US-tariff exposure as Hyundai.

Batteries & Biopharma — LG Energy Solution, Samsung Biologics

LG Energy Solution (373220). The order book is the bright spot — a backlog reported in the hundreds of GWh, with new 46-series cylindrical wins and a clear push into North American energy-storage (ESS) capacity to offset softer EV demand. Risk: EV-cycle timing and battery pricing.

Samsung Biologics (207940). The pure-play CDMO is broadening its model: it is launching a licensing business for its antibody and antibody-drug-conjugate (ADC) platform technologies (including its S-DUAL bispecific platform) and plans to open a European sales office in the Netherlands in Q3 2026, extending its global footprint beyond contract manufacturing. Risk: execution on the new platform-licensing axis is unproven.

Platforms — NAVER, Kakao, and LG Electronics' AI angle

NAVER (035420) & Kakao (035720). Both have rallied sharply since the new administration took office, on expectations that its “sovereign AI” agenda will favor domestic tech platforms — with Kakao additionally boosted by hopes for a Korean-won stablecoin (Kakao Pay is seen as a likely beneficiary). Policy signaling has been concrete: a former NAVER AI executive was appointed as the presidential secretary for AI policy in mid-June. Risk: several analysts warn the gains may be premature — the moves look policy/sentiment-driven and still need real commercial AI results to hold; some houses have trimmed targets as monetization is delayed.

LG Electronics (066570). Shares have run sharply in 2026 on a “physical AI” narrative (robotics, AI home, data-center cooling), alongside a three-pillar strategy raising future-growth investment. Next earnings are scheduled for Jul 23, 2026. Risk: expectations have run ahead of confirmed numbers.

Earnings & Disclosure Calendar

Korean large-caps report on a quarterly cadence; the heavy reporting windows are typically January, April, July and October. Samsung Electronics usually opens the season with preliminary (guidance) results early in the reporting month, ahead of full statements.

• Early July: Samsung Electronics preliminary Q2 figures (typical pattern; exact date to be confirmed by the company).
• Jul 23, 2026: Samsung Electronics full Q2 results and LG Electronics scheduled earnings (as reported).
• Through July: remaining large-caps (SK Hynix, Hyundai, Kia, LG Energy Solution, Samsung Biologics, NAVER, Kakao, Hanmi Semiconductor) report Q2 within the standard window — confirm exact dates via each company's IR / DART disclosures.

On price targets

We intentionally omit specific numeric price targets. For those, foreign readers can consult published sell-side research: domestically, houses such as Mirae Asset Securities and Samsung Securities; among global banks, Nomura, Morgan Stanley, Goldman Sachs and JPMorgan regularly cover these names. Always check the report date — Korea's AI-memory and platform names have moved fast, so older targets may be stale.
