SK Hynix killed a 15 billion dollar Solidigm IPO, and its shareholders won: what happened and why it matters

Why did SK Hynix cancel the Solidigm IPO? Because its own shareholders and South Korea's regulator pushed back, and the company concluded the deal was not worth the fight. On 23 October, SK Hynix said in a regulatory disclosure that it had decided to "discontinue its review of a potential pre IPO and initial public offering" for Solidigm, its US based solid state drive subsidiary, citing capital market conditions, as reported by Investing.com.

The market's reaction said everything. SK Hynix shares fell as much as 4.2 percent early in the session, then reversed to trade more than 4 percent higher as investors concluded that keeping Solidigm inside the group protected their interests. A listing that had been talked about as raising up to 15 billion dollars on Nasdaq is now off the table, and the episode has become a landmark in Korea's long running debate over corporate governance.

What is Solidigm?

Solidigm makes NAND flash memory and enterprise solid state drives, the high capacity storage used in servers and AI data centres. It was created after SK Hynix agreed in 2020 to buy Intel's NAND memory and SSD business in a deal worth about 9 billion dollars, completed in 2021.

The business has become far more valuable as AI has driven demand for storage. In the second quarter, Solidigm's high capacity enterprise SSD revenue grew more than threefold from the previous quarter, according to TIKR. That growth is why SK Hynix had explored raising money for Solidigm to expand production capacity and strengthen its competitiveness.

Reports had said Solidigm was considering a pre IPO fundraising round of about 5 trillion won, around 3.8 billion dollars, and had held talks with investment banks about a Nasdaq listing that could come as early as next year and raise up to 15 billion dollars.

Why shareholders opposed the listing

Korean investors have long complained about a practice known as duplicate listing, where a parent company spins off and lists a valuable subsidiary separately. Critics say it dilutes the parent's shareholders, because the most exciting growth asset ends up partly owned by new investors rather than fully owned by the parent.

That was the fear with Solidigm. SK Hynix shareholders, many of whom bought the stock for its exposure to AI memory and storage, worried that listing Solidigm in the United States would take part of that value away from them. An eToro analyst said shareholders "got the outcome they were pushing for", adding that the decision removes a governance worry and keeps Solidigm's value inside the company.

In Korea, the fastest way to lose shareholder trust is to list your best growth asset somewhere else. SK Hynix chose trust over cash.

The regulator added weight to the shareholders' argument. South Korea's financial regulator said earlier in the week that a US listing of Solidigm could break its dual listing rules, according to reports.

What it means for SK Hynix's funding

Dropping the listing does not remove SK Hynix's need for capital. Its existing factories cannot keep up with AI memory demand, and the company still wants to build a new US chip plant while it looks at other ways to pay for it. SK Hynix is generating huge profits from high bandwidth memory, which gives it room to fund expansion internally, but capital spending in the memory industry is enormous.

The analyst view is that SK Hynix must now fund Solidigm's growth without hurting buybacks and dividends. That balance will be one of the questions management faces when it reports third quarter results on 28 October, which we previewed in our report on the SK Hynix and Samsung earnings week.

Options include borrowing, partnerships with customers, or minority investments that do not involve a public listing. Each comes with trade offs, but none carries the governance stigma that a duplicate listing does in Korea.

A signal for Korean corporate governance

The decision matters beyond SK Hynix. Korea has been trying to close the so called Korea discount, the persistent gap between the valuations of Korean companies and their global peers, partly blamed on governance practices that favour controlling families over minority shareholders. Duplicate listings are one of the practices most often cited.

A high profile retreat by one of the country's most valuable companies sends a message to other conglomerates considering similar spin offs. The key lessons from the episode include:

• Minority shareholders in Korea can now block or delay value dilutive spin offs
• Regulators are willing to signal concerns about dual listings, including overseas
• Market conditions and volatility make large tech IPOs harder to price
• AI growth assets are increasingly seen as core value that should stay with the parent
• Companies must find funding routes that do not undermine shareholder returns

What comes next

Solidigm will keep growing inside SK Hynix, funded by the parent's cash flow and possibly by other financing. Investors will watch for any alternative structure, such as a strategic partner or a private stake sale, that brings in capital without a public listing.

For the market, the immediate focus shifts to SK Hynix's earnings on 28 October, which come on the same day as the US Federal Reserve decision. Strong results would reinforce the view that SK Hynix can fund its ambitions without spinning off its most promising assets.

SK Hynix's decision to abandon the Solidigm listing shows how much the balance of power has shifted toward minority shareholders in Korea. The company gave up a potentially huge capital raise to keep its most promising storage business fully in house, and the market rewarded it. The challenge now is funding AI scale growth without the shortcut of a spin off.
