How to Play SK Hynix Stock Amid a Potential $10B Solidigm IPO

Read MoreHide Full Article

Key Takeaways

  • SK Hynix's potential $10 billion Solidigm IPO could unlock value, but dilution concerns cloud the outlook.
  • Strong HBM demand fueled a 257% revenue surge & 557% operating profit growth in the second quarter of 2026.
  • SKHY's discounted valuation, rising earnings estimates and 50% implied upside support holding the stock.

SK Hynix (SKHY - Free Report) has just settled into its U.S. listing, which debuted on July 10, and it may now have a second blockbuster offering to manage. Its flash memory unit, Solidigm, is reportedly lining up an IPO of its own. According to Bloomberg as cited in a Yahoo Finance article, Solidigm has chosen Goldman Sachs and Morgan Stanley to lead the proposed IPO, which could raise around $10 billion and value the company at as much as $100 billion. The offering could take place as early as 2027. However, nothing is finalized yet.

A successful IPO doesn’t automatically translate into additional gains for SKHY investors. The investment case depends on both the value Solidigm unlocks and the implications of separating it from its parent.

SK Hynix’s Core AI-Memory Business Remains a Key Strength

SK Hynix's competitive position in AI memory remains central to its investment appeal.

Training and running increasingly sophisticated AI models require enormous computing power, creating demand for memory that can move data quickly between processors and storage. SK Hynix has established a strong position in high-bandwidth memory (HBM), which is used in AI accelerators supplied by companies such as NVIDIA (NVDA - Free Report) . Its relationships with major technology customers, including Microsoft (MSFT - Free Report) , also give it exposure to the broader expansion of AI infrastructure.

SK Hynix is also preparing for the next stage of the memory cycle. It has begun mass shipments of HBM4, its latest HBM generation, and expects production to increase through the rest of the year. Samples of the enhanced HBM4E generation have also been shipped, highlighting its efforts to maintain its technological lead.

The financial results show how powerful this demand has become. In the second quarter of 2026, SK Hynix generated 79.32 trillion won in revenues, a 257% increase from a year earlier. Operating profit rose 557% to 60.54 trillion won.

At the end of second-quarter of 2026, SKHY’s cash was about 88 trillion won. In August, the company announced a 40-trillion won ($28.7 billion) buyback-and-cancellation program, and it plans to return over half of 2025-2027 cumulative free cash flow to shareholders.

Capacity expansion is another priority. In August 2026, SK Hynix announced plans to invest approximately 54 trillion won ($38 billion) in domestic memory manufacturing, alongside a $4 billion U.S. packaging facility. These investments could help it capture more demand, although execution, capital intensity and the possibility of a future memory-market downturn remain risks.

Solidigm: Value Unlock or Value Leak?

Solidigm makes large-capacity SSDs for AI data centers. The business came from SK Hynix’s 2021 takeover of Intel’s flash memory business, and Dell Technologies and Tencent are among its buyers, which makes it a direct play on AI’s growing appetite for storage.

A separate listing could give investors a clearer view of Solidigm’s standalone worth. A public price would show what the NAND arm is actually worth, and outside capital could fund its expansion without leaning on the parent’s cash. If SK Hynix keeps a large stake, any rerating flows back to its shareholders.

But the picture is more complicated than that. Investors in South Korea have long been wary of parent companies listing valuable subsidiaries, and the Korea Times has reported that critics fear it could dilute existing shareholders. Once Solidigm trades on its own, SK Hynix would share that unit’s profits with new investors, and the market may apply a “holding-company discount”, valuing SK Hynix’s remaining stake at less than it is worth on paper.

Our Take

SK Hynix’s operating momentum and HBM leadership support the long-term case, and strong earnings growth plus a large buyback give existing shareholders a sturdy base. Valuation data shows why selling now would be a mistake. A discount to the industry, rising estimates and substantial implied upside all point the same way.

But those estimates rest on the memory cycle staying strong, and with heavy capacity spending underway, a cyclical downturn is the risk they leave out. They also don’t capture how a potential $10 billion Solidigm listing could impact SKHY—which could add more shares to the market and lower the value placed on SK Hynix’s stake.

Investors should wait for greater clarity on the offering’s valuation, ownership structure and use of proceeds. Existing shareholders should stay put. A more bullish stance requires proof that the listing creates value for SK Hynix’s own shareholders, not just for Solidigm’s.

SKHY currently carries a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
