SK hynix: Korean memory chip giant joins the Nasdaq

Investing in South Korean semiconductor giant SK hynix has just become a lot easier for international investors, with the stock listing on the Nasdaq. 

This is no run-of-the-mill listing either. It is reportedly the largest-ever US listing by a foreign company. So what does the company do, and what do investors need to know?

What is SK hynix?

SK hynix is a South Korean semiconductor giant, and the second-largest company in South Korea by market capitalisation. 

Particularly notable is the company’s leading position as a producer of high-bandwidth memory (HBM). In the first quarter of 2026, it had a 56.4% global share of the HBM market, making it the world’s dominant supplier.

HBM is a type of memory that allows for faster data transmission and lower energy use than traditional memory. This makes it well-suited for demanding workloads, where huge datasets need to be rifled through in short periods. 

As such, it’s a key component for state-of-the-art AI chips and has become an increasingly important part of the semiconductor industry amid the ongoing hardware boom. 

It is also the second largest supplier of NAND flash memory, with a worldwide market share of 18.5% in the same period. This type of memory is more likely to show up in consumer data storage devices, like SSDs and USB drives, and allows for data storage without an active power source.

How is SK hynix joining the Nasdaq?

The first thing to note is that this is not a conventional IPO by a newly public company. SK hynix already trades on South Korea’s Kospi, but its Nasdaq listing gives US and international investors a more direct route into the stock.

SK hynix is joining the Nasdaq by listing American Depositary Shares (ADS). These are shares traded on US exchanges that represent units of a foreign stock. 

This means SK hynix’s common stock is not being listed on the Nasdaq. Instead, a tradeable instrument representing the underlying shares is being listed, in order to give investors an easier way to gain exposure to the company. 

The offering price of each ADS is $149. Each ADS represents one-tenth of one SK hynix common share, meaning 10 ADSs are equivalent to one common share.

The listing has reportedly raised approximately $26.5bn, making it the largest-ever share sale by a company from outside the United States. 

Why is SK hynix joining the Nasdaq?

In joining the Nasdaq while the AI boom is booming, SK hynix is striking while the iron is hot. This allows the business to maximise its gains from listing, with that $26.5bn set to come in very handy.

The business says it will use these proceeds to construct a new fab and packaging plant, as well as to fund acquisition costs of extreme ultraviolet lithography scanners. These incredibly expensive tools are essential for cutting-edge chip production, and are only available from Dutch tech giant ASML.  

These are a key part of the company’s goal to expand production capacity to meet growing demand. 

Another thing joining the Nasdaq offers SK hynix is a significant broadening of its investor base. 

The company’s current main competitors in the memory market are Micron Technology and Samsung, both of which are more accessible to US and international investors. They already have access to other AI infrastructure plays too, including Nvidia, Broadcom, and AMD. 

Listing on a US exchange simply makes it easier for retail and institutional investors to get involved in SK hynix. Before the company joined the Nasdaq, those seeking exposure would likely have needed to use funds or ETFs that focused on the Korean market.

Finally, the listing also gives US investors a more direct way to compare SK hynix with Micron, the company’s closest US-listed memory-chip peer.

Essentially, SK hynix is reaching out to a broader basket of investors who already appear to have a taste for investing in AI infrastructure. 

What happened in SK hynix’s latest earnings?

Let’s move on to the numbers. SK hynix’s prospectus listed financial data for the three-month period ended 31 March. 

For this period, SK hynix's revenue of $34.5bn represented YoY growth of 198.1%. DRAM revenues increased by 189.7%, and comprised 77.3% of total revenues during the quarter.

The smaller NAND flash part of the business saw revenues grow by 258.5%. Gross profit margins widened from 57.3% to 79.3% as revenue growth significantly outpaced increases to cost of sales.

Meanwhile, total post-tax profits of $26.5bn, or ₩40.3tn, were an increase of 397.6% compared to the same period 12 months prior. 

SK hynix held roughly $13.9bn in cash and equivalents at the end of the quarter. It also spent ₩7.7tn on capital expenditure in the first quarter of 2026, equivalent to roughly $5.0bn. 

Capacity expansion is expensive, and despite its strong balance sheet and profitability, this week's raise can play a key part in meeting substantial funding requirements.

SK hynix risk factors

Though SK hynix has delivered strong growth, there are, of course, risks associated with the stock. These include, but are not limited to:

• Semiconductor industry: The business is heavily reliant on continued semiconductor demand. This is a largely cyclical industry, and periods of oversupply may impact results by reducing revenues and free cash flow. The current tight supply and high pricing encourage heavy capacity expansion, which could lead to a cooling of prices if supply catches up with demand.
• Competition: SK hynix faces considerable competition, and SK hynix may fall behind rival firms if it fails to improve manufacturing processes, meet evolving customer requirements, and obtain necessary supplies of raw materials and equipment.
• Exchange rates: A large proportion of SK hynix’s customers are based in the US and China. Fluctuations in exchange rates could therefore have a major impact on the company’s earnings.
• Korea: Any breakdown in economic or societal conditions in South Korea could considerably impact the business. This includes an escalation of tensions with North Korea, with whom the country is locked in a prolonged military stalemate. 

Why watch SK hynix?

Even if you don’t decide to invest in SK hynix, it’s still well worth watching how the stock performs after joining the Nasdaq. 

That’s because its trajectory will offer insight into investors’ interest in memory chip manufacturers and the broader AI hardware space. Of particular note is the company’s intention to use the listing to fund capacity expansion. 

This is a long-term goal, and so investor interest may be viewed as a signal of confidence in continued hyperscaler spending in AI hardware, rather than a source of simple supply chain exposure.

Elsewhere, Micron now has to deal with a more accessible competitor in the memory chip space. Will SK hynix’s massive market share in HBM turn investors away from the stock, or does the draw of the AI memory trade make this town big enough for the both of them?
