SK hynix's US-based NAND subsidiary, Solidigm, is exploring a path to a Nasdaq listing, yet a heavy debt burden and aging production infrastructure cast significant uncertainty over the plan.
According to a report by South Korea's Chosun Ilbo, SK hynix is preparing a Pre-IPO funding round for Solidigm worth between 5 trillion and 10 trillion Korean won. The company is soliciting investment interest from global alternative asset managers and sovereign wealth funds, with Morgan Stanley and Goldman Sachs reported as potential lead underwriters. Meanwhile, Solidigm has reportedly begun hiring executives responsible for SEC filings and external financial disclosures, further fueling market expectations of a Nasdaq listing.
SK hynix subsequently issued a clarification, stating that Solidigm is evaluating various options to strengthen its competitiveness but that no concrete plans have been finalized. The company added that it will provide updates by September 4 in accordance with disclosure requirements. This IPO exploration coincides with a surge in demand for high-capacity storage driven by AI infrastructure and inference workloads, providing a favorable market window for Solidigm.
AI storage demand creates a listing window
Solidigm's IPO preparations are unfolding against a backdrop of a recovering NAND market. According to TrendForce data, SK hynix Group (including SK hynix and Solidigm) generated approximately $7.53 billion in NAND revenue in the first quarter of 2026, a 44.6% sequential increase. This gave the group a 17.6% global market share, ranking second behind Samsung (31.6%).
On the product front, Solidigm has already launched a 122TB QLC enterprise solid-state drive, becoming the first manufacturer globally to release such a product. The company is also developing a next-generation enterprise SSD with a capacity of 245TB, which, according to a report by South Korea's The Korea Economic Daily, can store approximately 50,000 movies and is primarily aimed at the large-scale storage needs of AI data centers.
SK hynix acquired Intel's NAND flash and SSD business for approximately 10 trillion Korean won in 2020 and established Solidigm in the US in 2021 to manage the operations. A successful Nasdaq listing would extend SK hynix's capital market expansion strategy, following its own US listing via American Depositary Receipts (ADR) on July 10.
High debt levels and lingering financial concerns
Despite Solidigm's recent business recovery, its financial foundation remains fragile. According to the Chosun Ilbo, the company accumulated cumulative net losses of nearly 8 trillion Korean won between 2021 and 2023. By the first half of 2024, its shareholders' equity had fallen to a negative 906 billion Korean won, indicating complete capital impairment.
Although Solidigm returned to profitability for the full year of 2024 and emerged from capital impairment, the pressure on its financial structure has not fundamentally eased. The report shows that the company's debt ratio stood at a staggering 4,484.6% last year, roughly 14 times the level typically considered healthy (below 200%). This raises significant questions about its financial stability.
This high debt ratio not only suppresses valuation but also directly impacts Solidigm's ability to raise capital and set attractive pricing during the Pre-IPO and IPO stages, making potential investors cautious about the sustainability of its balance sheet.
Aging fabs hinder technological upgrades
Beyond financial pressures, the aging of production infrastructure also poses a core obstacle. Solidigm's wafer fab in Dalian, China, is its only overseas production base. Due to US export controls, the facility cannot import advanced equipment like EUV lithography machines, causing repeated delays to its planned upgrade and expansion.
According to a report by News Tomato in July, Solidigm plans to restart the long-shelved expansion of its second Dalian plant in the second half of 2026. This expansion is expected to add a V8 production line based on 238-layer NAND technology. Simultaneously, the first Dalian plant has begun converting its production lines to 192-layer NAND and is advancing equipment upgrades to replace older facilities.
If these upgrades proceed smoothly, they could enhance Solidigm's technological competitiveness and production capacity. However, capital expenditure pressures and the uncertainty of export controls remain unresolved variables that investors must consider when evaluating the company's listing value.
IPO significance: A key step in SK hynix's US strategy
For SK hynix, the strategic intent behind pushing for Solidigm's independent listing goes beyond mere fundraising. By establishing a separate capital market position for Solidigm on the Nasdaq, SK hynix can, to a certain extent, separate the NAND business from its core DRAM and HBM operations at the capital level, thereby diversifying its risk exposure. At the same time, it can leverage the liquidity of US capital markets to fund Solidigm's technology upgrades and capacity expansion.
This move also aligns with SK hynix's overall strategy of deepening its presence in the US market. Following its own ADR listing, a successful Nasdaq listing for Solidigm would create a dual-listing structure for the parent and subsidiary in the US capital market, further strengthening the company's strategic depth in the global memory market.
Currently, Solidigm's listing timeline has not been finalized. SK hynix has committed to disclosing the latest developments by September 4, at which point the market will receive a clearer signal.
