Why SK Hynix Paid $9 Billion for Intel's NAND — The Deal That Created Solidigm
Korea's Largest Overseas M&A · Two-Phase Closing · From NAND Division to Solidigm — Reshaping the Memory Supply Chain
Background
In 2020, SK Hynix held a commanding ~29% share of the global DRAM market, second only to Samsung. But in NAND flash — the memory technology used in SSDs, smartphones, and data centers — SK Hynix was a distant fourth or fifth, with roughly 10–11% market share versus Samsung (33%), Kioxia/WD (~32%), and Micron (~11%). Strengthening the NAND portfolio was a core strategic imperative.
Intel had entered the NAND and 3D XPoint (Optane) memory market in the 2010s as part of a broader memory strategy. But by 2020, NAND had become fiercely competitive with razor-thin margins, and the business was consistently unprofitable relative to Intel's core CPU and data center franchises. Incoming CEO Pat Gelsinger, who took office in February 2021, made the 'IDM 2.0' strategy — refocusing on semiconductor design and manufacturing — the centerpiece of Intel's revival. The NAND business was a distraction.
The deal was structured as a two-part closing to navigate Chinese antitrust approval. The first close (December 2021) transferred the SSD business, R&D, and employee base for $7.0B. The second close — covering Intel's NAND wafer manufacturing fab in Dalian, China — was contingent on Chinese SAMR approval and targeted for 2025 with an additional $2.0B payment.
The Dalian fab was a key asset: a state-of-the-art 3D NAND manufacturing facility representing significant capex investment, producing QLC and TLC NAND wafers. Its transfer to a foreign buyer required SAMR approval — a geopolitically sensitive process given rising US-China semiconductor tensions.

Industry Overview
NAND flash memory is a foundational semiconductor technology — the storage layer for virtually every digital device from smartphones to hyperscale data centers. The global NAND market generated approximately $60B in revenue in 2020, with cyclical swings of 30–50% based on supply/demand dynamics. Unlike DRAM (which is oligopolistic and controlled by Samsung, SK Hynix, and Micron), NAND is more competitive with five major suppliers: Samsung, Kioxia/WD, SK Hynix, Micron, and Intel.

The enterprise SSD segment (sold to cloud providers like AWS, Microsoft Azure, Google) was the highest-margin, fastest-growing portion of the NAND market. Intel's strength was specifically in this enterprise SSD segment — its data center SSD brand had deep relationships with hyperscalers. This was the strategic jewel SK Hynix was buying.
Key Players
Company Overview: Intel NAND Business
Intel's NAND business encompassed 3D NAND wafer production (Dalian fab, plus IM Flash JV with Micron for US supply), SSD design and branding (sold under the Intel SSD and Optane brands), and approximately 3,500 employees globally. Revenue was approximately $2.7B in 2020, concentrated in enterprise SSD sales to data centers. The Dalian, China fab was a cornerstone — a 3D NAND facility capable of producing 64-layer QLC and TLC NAND at scale.

Deal Structure
The deal was structured in two tranches to mitigate Chinese regulatory risk. The first close ($7.0B, December 2021) transferred all NAND IP, SSD product lines, employee base, and manufacturing equipment outside of China. The second close ($2.0B, targeted 2025) will transfer the Dalian fab upon Chinese SAMR approval. SK Hynix formed 'Solidigm' as a new subsidiary to house the acquired assets. Intel received $7.0B at first close and retains a $2.0B deferred payment contingent on the Dalian transfer.

Valuation
Valuing Intel's NAND business on a traditional EBITDA basis was difficult — the segment was marginally profitable or breakeven during the NAND downcycle. SK Hynix used an EV/Sales multiple (~3.4x on ~$2.7B revenue) as the primary framework, with the strategic premium reflecting market share acquisition and enterprise SSD synergies. Post-close synergies included combining R&D roadmaps (eliminating duplicate 3D NAND layer development) and cross-selling enterprise SSD to SK Hynix's existing hyperscaler relationships.

Deal Rationale
SK Hynix — Why Acquire at $9B?
- NAND market position was critically weak: 10% share in 4th–5th place vs. Samsung's 33% created a structural competitive disadvantage, especially as AI/cloud drove enterprise SSD demand.
- Enterprise SSD relationships: Intel's deep hyperscaler relationships (AWS, Azure, Google) gave Solidigm a distribution advantage SK Hynix could not build organically.
- Technology acceleration: Intel's 144-layer NAND stack technology (acquired, then advanced to 176-layer and 238-layer under SK Hynix) accelerated the roadmap by years.
- Portfolio diversification: SK Hynix's DRAM-heavy portfolio was vulnerable to DRAM cycles. NAND exposure balanced the revenue mix.
- Korea's largest outbound deal: strategic significance for SK Group's global ambitions beyond semiconductors.
Intel — Why Divest at $9B?
- NAND was consistently loss-making or sub-scale within Intel's portfolio — a capital-intensive business requiring $5–8B annual capex with volatile returns.
- Pat Gelsinger's IDM 2.0 strategy required focus: Intel needed every dollar for its foundry buildout (IFS) and CPU/GPU product recovery.
- $9B in cash at an opportunistic moment: the deal was announced when NAND prices were recovering — Intel monetized the business before the next downcycle.
- Optane (3D XPoint) was retained: Intel kept Optane technology, which it viewed as differentiated. (Optane was ultimately discontinued in 2022 — a separate strategic failure.)
- Geopolitical clean-up: exiting Dalian avoided long-term exposure to China semiconductor policy risk.
Post-Deal Assessment (2024 Q4 as of)
The timing of the first close (December 2021) was unfortunate: SK Hynix closed into the worst NAND downcycle in decades through 2022–2023, with NAND prices falling 50–60% and Solidigm posting significant losses. SK Hynix took inventory write-downs across its NAND portfolio. However, from late 2023 onward, the AI infrastructure boom drove unprecedented demand for high-capacity enterprise SSDs — the exact market segment Solidigm serves. Solidigm's 122TB QLC SSD product (announced 2024) positioned it at the frontier of AI data center storage. The Dalian second close remains pending as of 2024.
Positives
- NAND global share doubled — SK Hynix now competes credibly with Samsung in enterprise NAND.
- Enterprise SSD relationships with hyperscalers (AWS, Azure) are materially strengthened through Solidigm.
- NAND technology roadmap accelerated — 238-layer NAND development maintained competitive parity.
- AI storage demand (enterprise SSDs for training clusters) directly benefits Solidigm's product portfolio.
Risks & Concerns
- 2022–2023 NAND downcycle caused significant losses at Solidigm; SK Hynix absorbed these on top of DRAM weakness.
- Dalian fab second close ($2.0B) remains uncertain amid US-China semiconductor geopolitics; SAMR approval has not been granted.
- Integration of a US-based subsidiary (San Jose) into a Korean conglomerate carries cultural and management complexity.
- NAND markets remain cyclical — a repeat downcycle would test SK Hynix's NAND commitment.

Editor's Note
This deal is the defining case study in strategic M&A for market share acquisition in a semiconductor sector. The $9B price paid was justified not by trailing EBITDA but by the forward strategic value of doubling NAND position. The 2024 AI storage boom is beginning to validate the thesis — the ultimate test is whether Solidigm can sustain enterprise SSD leadership as Samsung and Micron respond.
Key Concepts in This Deal
Buying a competitor or target specifically to gain percentage points of market share — justified by strategic position rather than traditional EBITDA multiples.
A deal structure where completion happens in sequential stages, often used when one asset requires separate regulatory approval (here, Chinese SAMR for the Dalian fab).
When EBITDA-based valuation is not applicable (near-breakeven businesses), EV divided by revenue serves as the primary benchmark.
Non-volatile storage memory used in SSDs, smartphones, and data centers. More competitive and cyclical than DRAM; 5 major global suppliers.
Intel's strategic pivot under Pat Gelsinger — refocusing on semiconductor design and building a foundry business (IFS), which required divesting non-core assets like NAND.
The sale of a business unit or division from a larger company — here, Intel's NAND segment was carved out and transferred to SK Hynix as Solidigm.
Frequently Asked Questions
Why did SK Hynix pay $9B for a business that was barely profitable?
Market share in semiconductors is a strategic asset that cannot be easily built organically. Going from 10% to 20% global NAND share in one transaction — and gaining enterprise SSD relationships with AWS, Azure, and Google — would have taken SK Hynix 5–10 years and $15–20B in capex to replicate internally. The $9B acquisition was cheaper and faster than organic build. The EBITDA was low because NAND was in a downcycle — the strategic value was forward-looking.
Why is the Dalian fab transfer still pending?
The Dalian fab is a semiconductor manufacturing facility in China, and its transfer to a Korean buyer requires approval from China's SAMR (State Administration for Market Regulation). Given escalating US-China semiconductor tensions and China's strategic sensitivity about semiconductor manufacturing assets leaving Chinese control, SAMR approval has been delayed. The $2.0B second close remains contingent on this approval.
What is Solidigm and how has it performed?
Solidigm is the company created from Intel's NAND team, SSD products, and IP, headquartered in San Jose, California. It operates as a wholly-owned subsidiary of SK Hynix. Initial performance was challenged by the 2022–2023 NAND price downcycle. From 2024, Solidigm benefited from the AI storage boom — its high-capacity QLC NAND SSDs are optimized for hyperscale data centers building AI training infrastructure.
Why did Intel sell its NAND business?
Under CEO Pat Gelsinger's IDM 2.0 strategy (announced 2021), Intel refocused on CPU/GPU design and building a semiconductor foundry business (Intel Foundry Services). NAND required $5–8B in annual capex and generated volatile, often negative returns within Intel's portfolio. The $9B monetization provided critical capital for Intel's foundry investment without diluting equity. Intel retained Optane (3D XPoint) technology, which it discontinued in 2022.
How did this deal change the global NAND market structure?
Pre-deal, NAND had 5 meaningful players. Post-deal, SK Hynix+Solidigm consolidated into a clear #2 position (~20% share) behind Samsung (~33%), creating a more bipolar market dynamic. The Kioxia/WD JV partnership (~28% combined) became more vulnerable to this consolidated competitor. For enterprise SSD customers, Solidigm's independence from SK Hynix's core operations means it maintains its own go-to-market approach, preserving Intel SSD customer relationships.
Was the deal timing good or bad for SK Hynix?
The announced timing (Oct 2020) was excellent — NAND was recovering from a trough. But the first close (Dec 2021) coincided with the beginning of a severe NAND downcycle through 2022–2023. SK Hynix absorbed Solidigm's losses on top of its own DRAM weakness. From a 5-year perspective, the 2024 AI storage demand surge vindicates the strategic logic — but the short-term financial pain was significant.
