SK Square

SK Square is SK Group's intermediate holding company for semiconductor and ICT investments, created when SK Telecom was split on November 1, 2021 into a surviving telecom entity and an ICT investment arm.

Its asset base centers on SK hynix: press reports state that as of the end of June 2026 it was the largest shareholder with a 20.5% stake, or 146.1 million shares.

In the company's investor relations net asset value table dated August 6, 2026, SK hynix accounted for 218.42 trillion won of a total NAV of 223.6 trillion won, followed by TMAP Mobility at 1.46 trillion won, SK Shieldus at 1.02 trillion won, SK Planet at 0.62 trillion won and Contents Wavve at 0.26 trillion won.

Consolidated revenue comes from consolidated units such as SK Planet and Contents Wavve, while SK hynix is accounted for by the equity method and its revenue is not consolidated, producing the classic holding-company mismatch between small revenue and large profit.

In 2026 the company accelerated disposals of non-core assets, selling digital advertising firm Incross to SK Networks in January and app-market operator ONE Store in June.

New investments are channelled through TGC Square, an overseas vehicle set up in Singapore in 2023 in which SK Square holds 34.9%, with SK hynix, Shinhan Financial Group and LIG Nex1 among co-investors.

Through TGC Square it has invested a cumulative 30 billion won in seven AI and semiconductor companies in the United States and Japan and has said it will deploy up to 100 billion won in total, noting that the valuation of early investee d-Matrix in the United States rose more than sevenfold from entry.

Organizationally, the former chief investment officer and portfolio functions were reorganized into a Strategic Investment Center, and an 'AI Innovation' unit created in early 2026 is introducing AI agents into deal screening and portfolio management.

Within Korea's listed holding companies, it stands out as a case where asset value is concentrated in a single semiconductor subsidiary, so both earnings and share performance track the memory cycle closely.

Second-quarter 2026 consolidated results were revenue of 328.5 billion won, operating profit of 19.2354 trillion won and net profit attributable to owners of 18.6748 trillion won, all quarterly records.

That operating profit was more than double the 8.2783 trillion won posted in the first quarter of 2026 and an order of magnitude above the 1.4011 trillion won of the second quarter of 2025.

The driver is unambiguous: according to an NSP News report dated August 14, 2026, second-quarter equity-method gains reached 19.2672 trillion won, exceeding total operating profit, as SK hynix's strong results flowed straight through the accounts.

Revenue, by contrast, has stayed in a narrow band, at 406.6 billion won in Q2 2025, 407.9 billion won in Q3, 194.2 billion won in Q4, 300.3 billion won in Q1 2026 and 328.5 billion won in Q2 2026, also reflecting a smaller consolidation scope after the Incross and ONE Store disposals.

Annually, revenue declined for four straight years, from 2.3706 trillion won in 2022 to 2.2765 trillion won in 2023, 1.9066 trillion won in 2024 and 1.4115 trillion won in 2025, while operating profit moved from a 2.3397 trillion won loss in 2023 to profits of 3.9126 trillion won in 2024 and 8.7974 trillion won in 2025.

The fact that the 2025 operating margin computes to 623.3% is itself a description of the income structure: the profit and loss statement is dominated by accounting gains on holdings, not by revenue-based margins.

Cash flow deserves attention, since 2025 net profit attributable to owners of 8.8241 trillion won compared with operating cash flow of only 387.2 billion won, versus 189.9 billion won in 2024.

Equity-method income is non-cash, and actual cash arrives only through subsidiary dividends and disposal proceeds, so there is a timing gap between reported profit and distributable cash.

The balance sheet has strengthened: with total liabilities around 2.5214 trillion won, owners' equity grew from 15.2018 trillion won in 2023 to 27.6365 trillion won in 2025, cutting the debt-to-equity ratio from 29.1% in 2022 to 9.0% in 2025.

SK Square's profit and loss is a function of the memory semiconductor cycle. A World Semiconductor Trade Statistics forecast cited by SK hynix's newsroom projected the global semiconductor market growing more than 25% in 2026 to about 975 billion dollars, with memory expanding at a 30%-plus rate.

In high bandwidth memory, Counterpoint Research data showed SK hynix holding first place with a 58% share in the first quarter of 2026, down from 69% a year earlier, while Samsung Electronics was expected to gain share as the first HBM4 supplier to NVIDIA.

In commodity DRAM, capacity crowding-out from HBM is visible: per a Money Today report of August 20, 2026, Morgan Stanley expected third-quarter DDR4 prices to rise 50% quarter on quarter with a further 10% gain in the fourth quarter. Demand-side pressures coexist.

An iM Securities forecast relayed by Investing.com saw PC, smartphone and tablet shipments all declining in 2026, with the degree to which server demand offsets that decline identified as the key swing factor for cycle durability.

Several research houses argued that big tech and neocloud capital spending is likely to continue through 2027, but that funding conditions and data center investment efficiency could become an inflection point from 2028.

On positioning, SK Square is a shareholder rather than a manufacturer, so it cannot directly control variables such as HBM technology gaps or pricing power and instead absorbs their outcome through equity-method accounting, which distinguishes it from semiconductor materials and equipment names.

On confirmed facts, the first swing factor for future earnings is SK hynix's profit and its return policy.

According to Digital Times and Daum reports, in August 2026 SK hynix announced a 40 trillion won buyback and cancellation program alongside a policy of returning 'more than 50%' of cumulative free cash flow for 2025 to 2027, and it also raised its fixed dividend for 2025 to 2027 to 1,500 won per share from 1,200 won.

Larger subsidiary dividends and returns feed directly into SK Square's cash inflow channel and narrow the timing gap between equity-method income and actual cash.

The second factor is execution of its own shareholder returns: the company cancelled 40 billion won of treasury shares acquired in the first half of 2026 and said it will buy and cancel another 70 billion won by early next year, while press reports from March 2026 outlined a 310 billion won package combining 110 billion won of buybacks and 200 billion won of cash dividends.

Third is a change in market structure, as material from Shinhan Investment and a TradingKey report noted that SK hynix began trading American depositary receipts on Nasdaq on July 10, 2026, with new-share issuance implying dilution of roughly 2%.

Fourth is new investment: management said it is preparing meaningful investments across the semiconductor value chain, but an Asia Today report of July 1, 2026 said no headline-scale deal had yet been confirmed and cited industry talk of a goal to secure 3 trillion won of investment resources next year.

Finally, the company has set value-up targets of cutting its net asset value discount below 30% and lifting its price-to-book ratio above 1 times by 2028, and it disclosed that the discount had narrowed to 38% as of the August 13, 2026 close from 50.1% at the end of the second quarter of the prior year.
