SK Hynix IPO filing reveals business window; company targeting $149 per share, validating HBM supply dominance.
SK Hynix's SEC F-1 filing for its US IPO reveals the company's ambitious capital expansion plans and market positioning in memory semiconductors. The company is offering 17,790,000 shares on Nasdaq under the ticker SKHY, representing approximately 2.50 percent of its total issued and outstanding common shares of 712,702,365 shares. The shares are represented by American Depositary Shares (ADS), with Citibank, N.A. serving as the depositary. Pricing is yet to be determined.
The IPO proceeds will fund two major capital projects: construction of production facilities in Korea—Fab 1 at the Yongin complex and the P&T7 advanced packaging plant in Cheongju—totaling ₩45.5 trillion ($29.7 billion), and acquisition of EUV scanners at approximately ₩11.9 trillion ($7.8 billion) with delivery by December 2027. The company expects to fund amounts exceeding net IPO proceeds through cash flows from operations, existing and future credit facilities, debt securities, and other funding resources.
SK Hynix manufactures HBM, DDR DRAM, LPDDR, and GDDR chips, and supplies enterprise SSDs. It identifies Samsung, Micron, and ChangXin Memory Technologies (CXMT) of China as primary DRAM competitors, while Samsung, Kioxia, Micron, and SanDisk compete in NAND. According to the company, it holds the number one position in HBM supply with a 56.4 percent market share (IDC), the largest DRAM supplier share at 29.1 percent, and number two in NAND with an 18.5 percent revenue share.
According to Gartner, total semiconductor revenues are forecast to reach $1.32 trillion in 2026 and grow at a compounded annual growth rate of 38.9 percent from 2025 to 2027, reaching $1.56 trillion by 2027. The memory semiconductor segment is central to this expansion. Gartner projects the overall memory semiconductor market will increase from $216 billion in 2025 to $633 billion in 2026—a year-over-year growth of 192.7 percent—and reach approximately $748 billion in 2027 at a 86.0 percent CAGR. This growth is driven primarily by rapid HBM expansion supporting AI computing and storage demand, alongside strong increases in average selling prices for DRAM and NAND products.
DRAM revenues are forecast to grow at a 67.3 percent CAGR from $143 billion in 2025 to $401 billion in 2027. HBM revenues specifically are projected to increase from $33 billion in 2025 to $86 billion in 2027, representing a 60.5 percent CAGR. NAND revenues are forecast to grow at a 123.7 percent CAGR from $68 billion in 2025 to $341 billion in 2027.
Based on Gartner and IDC figures, SK Hynix generated approximately $18.6 billion in HBM revenues in 2025 (56.4 percent of the $33 billion market), and $32.01 billion in non-HBM DRAM revenues (29.1 percent of the $110 billion market), with HBM accounting for approximately 42 percent of its overall memory revenues in 2025.
Pricing dynamics are favorable across memory categories. Traditional DRAM's average selling price increased 45.2 percent year-over-year in Q4 2025 and is forecast to increase 136.4 percent and 198.1 percent year-over-year in Q1 2026 and Q2 2026 respectively, with favorable pricing expected throughout 2026. HBM has maintained double-digit year-over-year average selling price growth throughout 2024 and 2025, with robust pricing trends expected to continue over the next several quarters. NAND flash memory's average selling price is expected to increase 111.1 percent and 243.8 percent in Q1 and Q2 2026 respectively, and more than 250 percent in Q3 and Q4 2026.
SK Hynix has focused sales and marketing on expanding long-term strategic customer relationships, believing its strengths in HBM, server DRAM, and enterprise SSDs enable it to mitigate cyclicality risks in the memory semiconductor market. The company's six-point strategy emphasizes solidifying technological leadership and memory innovation; strengthening customer and partner relationships and developing customized HBM products; pursuing production capacity expansion in Korea; investing in a U.S.-based advanced packaging facility to support AI memory demand; expanding its role beyond memory semiconductor production in the AI era; and focusing on financial management to provide sustainable shareholder returns. The company states: "Our future long-term growth depends to a significant extent on our ability to increase production capacity."
Current expansion projects include the Yongin Semiconductor Cluster, a multi-fab complex in Korea where the first fab will consist of six cleanrooms with three additional fabs planned subject to market conditions. Construction of the first fab began in February 2025, with phase 1 cleanroom expected to open in Q1 2027. The M15X facility in Cheongju is a next-generation extension fab dedicated primarily to HBM and high-performance DRAM production, incorporating EUV lithography and advanced cleanroom automation. Wafer input began in Q1 2026 with production gradually ramping up. The P&T7 advanced packaging plant in Cheongju, currently under construction and primarily for AI memory product packaging, is targeted for completion by end of 2027.
As part of a U.S. manufacturing strategy, SK Hynix is investing approximately ₩5.9 trillion ($3.8 billion) to construct a production facility in West Lafayette, Indiana focused on advanced HBM packaging for AI accelerators, targeting first cleanroom completion in H2 2028.
Capital expenditure has increased significantly. Cash outflows for acquisitions of property, plant and equipment totaled ₩27,519 billion ($18.2 billion) in 2025, ₩15,946 billion ($10.5 billion) in 2024, and ₩8,325 billion ($5.5 billion) in 2023. In the first quarter of 2026, capital spending reached ₩7,657 billion ($5.9 billion) compared to ₩6,284 billion ($4.2 billion) in Q1 2025. SK Hynix plans to increase capital expenditures considerably in 2026 compared to 2025.
The company expects capacity increases will lower per-unit manufacturing costs and that continued efficiency and technical capacity improvements across successive fabs will significantly impact financial condition and results of operations.
No plans have been revealed to increase Solidigm's Dalian plant capacity. As Solidigm's NAND technology differs from SK Hynix's, Solidigm NAND cannot be manufactured in SK Hynix fabs. The F-1 filing does not specify investment in Solidigm's Dalian operations or discuss Solidigm's technology roadmap. Solidigm, focused on high-capacity enterprise SSDs, is notably absent from SK Hynix's AIN-D high-capacity flash plans.
SK Hynix stated that the Chinese State Administration for Market Regulation granted conditional business combination approval for SK Hynix's Intel SSD operation acquisition, including obligations to maintain reasonable pricing and production levels and support [text incomplete in source].
