The company dates its semiconductor business to Hyundai Electronics in 1983. A 2026 SEC filing says the legal entity was established on October 15, 1949, with its head office in Icheon, Gyeonggi Province. SK square Co., Ltd. is the largest shareholder, at 20.50% as of June 30, 2026, after the company joined SK Group in 2012. President and CEO Kwak Noh-Jung leads it. SK hynix sells DRAM, including high-bandwidth memory, and NAND flash. For Q3 2026 it reported preliminary revenue of 104.6155 trillion won, operating profit of 83.3338 trillion won, and net profit of 39.7756 trillion won. The company said the independent audit is not finished. It said HBM4 shipments expanded in the quarter and that it expects HBM4 to exceed HBM3E in shipments and revenue in the fourth quarter. Cash and equivalents were 114.5 trillion won and net cash was 98.7 trillion won at Sept. 30, 2026. Q2 2026 revenue was 79.3187 trillion won, and Q2 net profit of 93.9226 trillion won included large investment-asset gains, mostly Kioxia. The Oct. 23 notice and the Oct. 28 call say Solidigm stopped its IPO review and name no replacement financing, no US fab site, and no schedule. SK hynix told Reuters it is installing equipment at its Dalian NAND plant in consultation with the US government and did not disclose a layer count. The Q3 release and call transcript do not confirm a move from 192-layer to 240-layer or higher NAND, a US license for that equipment, or a new US NAND factory. The company has not confirmed a 10 percent ASML Korea parts increase, and those Q3 documents do not confirm or deny it.

On Oct. 23, 2026 SK hynix said Solidigm has discontinued its review of a possible pre-IPO fundraising and US IPO because of capital-market conditions and share-price trends. The company said the decision does not change Solidigm's need for more US production capacity, and that it will keep looking at timing, scale and financing. Reuters reported that Korean authorities had raised shareholder concerns and that people familiar with the suspended plan had spoken of a possible $15 billion sale and a $150 billion valuation, figures SK hynix did not state.
Samsung told Reuters that upgrades at its China plants are underway in consultation with Washington and do not expand capacity or add a factory, while SK hynix said it is installing equipment at its Dalian plant in consultation with the US government. People familiar with the plans told Reuters the work is aimed at NAND above 200 layers, including a Samsung conversion toward 286-layer chips in Xian and an SK hynix move toward 240 layers or more in Dalian. Reuters could not determine how far US export licenses cover the equipment.

That post states no new capacity or investment figure.
DRAM is the lead memory business. The company said Q2 2026 profitability came from high-value products including HBM and DRAM for AI servers, and that HBM4 mass shipments started in the quarter. FY2025 HBM revenue more than doubled from the prior year. No current DRAM-versus-NAND revenue split was taken from the documents opened for this profile.
NAND is the other memory line. The company said Q2 prices rose for both DRAM and NAND, and that sales of eSSD were part of the high-value mix. It said 321-layer NAND already represents the largest share of NAND production and is planned to reach about 50% of domestic production capacity by the end of 2026.

Holds a first Partners Day in Japan
On Oct. 29, 2026 SK hynix held its first Partners Day in Chiba, Japan, with executives from more than 20 suppliers, including Shin-Etsu, SUMCO, Tokyo Electron, DISCO, and Advantest. The Oct. 30 newsroom post says the company shared its mid- to long-term business direction and technology roadmap so partners could plan facility investments and production capacity.

Reports record Q3 revenue above 100 trillion won
On Oct. 28, 2026 SK hynix reported preliminary Q3 revenue of 104.6155 trillion won, operating profit of 83.3338 trillion won, and net profit of 39.7756 trillion won. It said HBM4 shipments expanded and that it expects HBM4 to exceed HBM3E in shipments and revenue in the fourth quarter. Agreements with 14 customers cover more than half of 2027 and 2028 capacity, the company said. The board resolved a 14 trillion won dividend and a 20 trillion won repurchase, of which about 10 trillion won is for employee compensation and is excluded from the shareholder-return total.
On Oct. 23, 2026 SK hynix said Solidigm stopped reviewing a pre-IPO raise and a US listing because of capital-market conditions and the share price. The company said US factory needs are unchanged and that it will keep studying financing. Reuters said people familiar had discussed a $15 billion raise and a $150 billion value, which the company did not confirm, and that Korean regulators had questioned a dual listing.
SK hynix says it is installing equipment in Dalian
SK hynix told Reuters on Oct. 21, 2026 that it has been installing equipment at its Dalian NAND plant in consultation with the US government, and it did not disclose the production plan. Three people said the aim is 240 layers or more, and one person said the site now makes 192-layer NAND. Reuters could not determine the export-license coverage. That person also said the company is discussing a new US NAND factory. No site was named, so this is not a chosen factory.
Says Solidigm capital plan is undecided
On Oct. 1, 2026 SK hynix said no matters had been determined regarding Solidigm's future operations or capital plans, repeating a September regulatory filing. It said internal and external financing remain options and that any choice will be judged by its effect on existing shareholders and long-term corporate value. Korea Herald reported investor concern about a separate U.S. listing after Reuters described bank bake-off meetings; the company did not confirm a listing. This is not a closed IPO.
Has not confirmed the reported ASML Korea parts increase
Industry sources told The Elec that SK hynix accepted a 10 percent increase on ASML EUV and DUV replacement parts for South Korea, effective on deliveries from January 2027. The Oct. 28, 2026 earnings release and the call transcript opened for this pass do not confirm or deny that increase, and they do not state a Dalian layer count, a US export license, or a chosen US NAND site. ASML has not confirmed the change on a page opened here. An earlier title said the company had accepted the increase. That acceptance is not a company statement. Official Q3 results are now out and remain preliminary pending audit.
Nasdaq ADR listing and HBM4 mass shipments
On July 10, 2026 the company marked a Nasdaq ADR listing in New York. On July 29 it reported record Q2 results and said HBM4 mass shipments had begun in the quarter, with HBM4E samples already at customers and volume production targeted for 2027.
