1. Semiconductors
Samsung Electronics convened a board meeting on 21st August and resolved to return between 90 trillion and 110 trillion won to shareholders this year — roughly five times the previous domestic record of 20.3 trillion won set in 2020, and the largest such commitment in the company's history. The decision follows Samsung's existing policy of allocating 50% of free cash flow (FCF) generated between 2024 and 2026 to shareholder returns. Approximately 30 trillion won will be distributed in cash during the third quarter, including the regular quarterly dividend; the precise size and form of the remaining payout — whether dividends, share buybacks, or cancellations — will be finalised at a board meeting in late January next year. Separately, the board approved a roughly 15 trillion won buyback of treasury shares for employee compensation, a move also designed to mollify shareholders who had grown restive over recently expanded semiconductor performance bonuses.
The announcement came two days after SK Hynix, on 19th August, resolved to cancel 40 trillion won of its own shares and to return more than 50% of FCF to shareholders, setting the stage for an open rivalry in capital returns between South Korea's two semiconductor giants. On the same day, analysts warned that a surge in demand for enterprise solid-state drives (eSSD) used in AI data centres had intensified supply bottlenecks in the NAND flash market, with contract prices forecast to rise a further 20–25% in the third quarter.
2. Substrates
The flip-chip ball-grid-array (FC-BGA) substrate businesses of Samsung Electro-Mechanics and LG Innotek — critical components for high-end semiconductor packaging — were running at average utilisation rates of around 90% in the first half of the year, driven by demand from AI servers and data centres, according to figures confirmed on 14th August. Samsung Electro-Mechanics saw its utilisation rate rise from 86% in the first quarter to 89% across the first half, supporting an ongoing improvement in profitability.
3. Internet
Naver announced on 20th August that its Team Naver digital-twin platform had been adopted as a national standard by Saudi Arabia. Reports on the same day highlighted an intensifying competitive border-crossing between Naver and Coupang, the two dominant forces in South Korean e-commerce. Coupang, whose logistics network is its core strength, is beta-testing a payments service called "Rocket Pay", while Naver, whose payments infrastructure is its stronghold, is piloting a logistics service called "N-Delivery" (Fulfilled by Naver). Each is attempting to neutralise the other's chief competitive advantage.
4. Power Equipment
LS Electric announced on 18th August that it had signed a power-distribution-solution supply contract with Bloom Energy of the United States, worth approximately $34.26m (around 48.6 billion won). Under the agreement, LS Electric will supply an integrated distribution system for a data centre that Bloom Energy is developing in Wyoming. The deal reflects LS Electric's accelerating push into the North American data-centre power-infrastructure market, leveraging its local manufacturing base.
5. Defence
The United States Army signed a prototype development contract on 18th August (local time) with Hanwha Defense USA, the American subsidiary of Hanwha Aerospace, for the Mobile Tactical Cannon (MTC) programme. Hanwha Aerospace will supply a prototype of a wheeled self-propelled howitzer derived from its K9 platform. Should the company secure the subsequent full production contract, the total opportunity is estimated at up to 30 trillion won.
6. Nuclear Energy
Bill Gates, chairman of TerraPower, visited South Korea on 13th August and held discussions on small modular reactor (SMR) co-operation with SK, HD Hyundai, and Doosan Enerbility on 14th August. Doosan Enerbility announced at the meeting that it had signed a contract to manufacture key components for TerraPower's sodium-cooled fast reactor, including the reactor protective vessel and supporting structures.
7. K-pop
Enhypen, signed to Big Hit Music under Hybe, released their eighth mini-album, *THE SIN : BLISS*, on 21st August. It is the group's first release as a six-member act following the departure of Heeseung. The music video for the lead single "Bloody Paradise" was unveiled on 22nd August, and the group performed on KBS2's *Music Bank* on the same day as the album's release.
8. Retail
Shinsegae Department Store has opened a dedicated fashion-accessories concourse on the basement level of its flagship Gangnam branch, bringing together scarves, hats, bags, and related goods in a single specialist zone. Meanwhile, E-mart is running a flash sale from 21st to 23rd August on domestically caught autumn blue crab, priced at 689 won per 100 grammes.
9. Hotels
Lotte Hotel Seoul has completed a 15-month renovation and relaunched on 14th August under the upscale brand name "The Grand Lotte Seoul". The overhaul — the most extensive in 18 years — enlarged guest rooms and elevated the property's luxury positioning as it bids to compete at the top of Seoul's premium hotel market.
10. Capital Markets
The KOSPI, South Korea's main stock index, plunged 5.8% on 19th August as a retracement in semiconductor stocks collided with rising US Treasury yields and geopolitical anxiety in the Middle East. It recovered swiftly the following day, clawing back above 6,800 after SK Hynix's 40 trillion won shareholder-return announcement triggered a broad rally in large-cap chip shares.
On 21st August, Samsung Electronics' record-breaking return pledge added further momentum to heavyweight semiconductor names. However, simultaneous rises in long-term US interest rates and crude oil prices, compounded by profit-taking, sent the KOSDAQ — a secondary index dominated by smaller growth companies — tumbling more than 5% intraday, breaching the 800 level and triggering an automatic sell-side circuit breaker ("sidecar"). The session ended with a marked divergence: the KOSPI held up relatively well, closing at 6,912, carried by the twin semiconductor giants' return rallies, while the KOSDAQ remained under pressure as capital rotated sharply into blue-chip chip stocks and away from smaller-caps.
