Origin
The predecessor of SK hynix was Hyundai Electronics under the Hyundai Group. During the 1997 Asian financial crisis, the Hyundai Group disintegrated, and its semiconductor business saw its debt-to-equity ratio soar to 206%, leading to years of creditor management and near bankruptcy. In 2012, SK Group Chairman Chey Tae-won went against widespread opposition to acquire a 21.05% stake for approximately 3.4 trillion won (about 3 billion USD). The acquisition logic was that SK Group already had two cash cows in oil and telecommunications and needed a third core asset with global competitiveness. At the same time, Chey Tae-won judged that semiconductors were a strategic national industry for South Korea, and the industry downturn presented a prime opportunity to buy at the bottom.
Milestones
1997
Crisis Failure
The Asian financial crisis hit the Hyundai Group hard. Hyundai Electronics (predecessor of SK hynix) was burdened with debt, with its debt-to-equity ratio reaching 206%. The company was forced into creditor management, slipping from a core chaebol affiliate to the verge of bankruptcy and liquidation, with management losing almost all operational autonomy. This phase lasted from 1997 to 2001.
2012
Acquisition Turning Point
In 2012, SK Group Chairman Chey Tae-won signed the acquisition agreement in a Seoul creditor bank meeting room, securing a 21.05% stake in hynix for approximately 3.4 trillion won (about 3 billion USD). At the time, the market generally looked down on the deal, believing SK had taken on a debt black hole, and opposition both inside and outside the board of directors was fierce.
2013
Deep Cultivation PMF
Following the acquisition, SK hynix stabilized its position as the world's second-largest in the DRAM market, allowing its cash flow to recover. Around 2013, it began secret research and development into HBM (High Bandwidth Memory). For the next decade, market response was lukewarm, and HBM shipments remained a very small percentage for a long time, but the company continued its investment without wavering. This phase lasted from 2013 to 2015.
2022
Counter-cyclical Bet Failure
The memory industry entered a severe winter, and SK hynix suffered consecutive massive losses from the fourth quarter of 2022 to the first half of 2023, with quarterly operating losses reaching trillions of won. Amid universal opposition and tight cash flow, CEO Kwak Noh-jung insisted on counter-cyclically increasing the HBM R&D budget by 30%, which outsiders questioned as a desperate, all-in gamble. This phase lasted from 2022 to 2023.
2024
Explosion Turning Point
With the explosion in demand for AI computing power, SK hynix's HBM3 and HBM3E took the lead in passing NVIDIA's certification and became the primary supplier thanks to its leading MR-MUF packaging technology. In 2024, the revenue share from HBM products climbed rapidly, driving the company's annual operating profit to a historic high and successfully turning a profit.
2026
Reaching the Summit Growth
In the first quarter of 2026, SK hynix recorded a quarterly operating margin of 72%, surpassing NVIDIA's 65%, and topped South Korea's stock market capitalization rankings, holding over 57% of the global HBM market share. During the same period, the company announced a 54 trillion won investment to expand production, held a ground-breaking ceremony for its HBM production base in Indiana, USA, and simultaneously initiated a share buyback and cancellation program totaling 40 trillion won.
Turning Points
- Chey Tae-won's counter-cyclical acquisition of debt-ridden hynix in 2012 for about 3 billion USD marked the starting point of the entire comeback.
- Persisting with investment during a decade of cold benches and zero returns for HBM, waiting for the AI computing power boom to arrive.
- The CTO line remained steadfast during the massive loss period in 2023, as Kwak Noh-jung counter-cyclically raised the HBM R&D budget by 30%.
- Being the first to pass NVIDIA's certification and tie into its GPU supply chain, locking Samsung out of the HBM3E door.
Failures & Pitfalls
- Following the 1997 Asian financial crisis, the debt-to-equity ratio reached 206%, leading to years of creditor management and near bankruptcy.
- For about a decade after the technical investment in HBM, market response was lukewarm, and shipment volumes failed to amount to much for a long time.
- During the memory industry downturn from 2022 to 2023, the company experienced consecutive quarters of operating losses running into the trillions of won.
- In the early acquisition period of 2012, the deal was generally looked down upon by the South Korean market, which believed taking over for 3 billion USD meant acquiring a debt black hole.
关键成功要素
- Counter-cyclical judgment: Having the courage to expand production and make acquisitions at the industry bottom when competitors were cutting investments.
- Long-termism betting: Sticking to the HBM track through a decade of cold benches until the AI tailwind arrived.
- Process barrier: MR-MUF packaging technology became a moat for HBM yield and supply stability.
- Binding key customers: Deep collaboration with NVIDIA made HBM the computing blood of AI chips.
- Parent company transfusion: Cash flows from SK Group's oil and telecommunications sectors supported hynix through industry cycles.
Lessons
- Acquiring distressed quality technology assets on the verge of bankruptcy is faster for securing core tracks than building from scratch.
- Victory or defeat in the semiconductor industry is often decided at the bottom of the cycle; counter-cyclical investment yields higher returns than pro-cyclical expansion.
- A technical bet with ten years of unprofitability can only be sustained when backed by a parent company with strong cash flows.
- Winners in the AI era are not necessarily large language model companies; memory vendors selling computing blood can also reach the top.
- When facing decisions with unanimous internal opposition, an entrepreneur's long-term vision determines the company's ceiling.

Competitors / Peers
The HBM market exhibits an oligopolistic competitive structure. Samsung Electronics remains the global leader in total DRAM volume, but suffered repeated delays in NVIDIA certification for HBM3E between 2024 and 2025, allowing SK hynix to suppress it to second place, while accelerating its pursuit of HBM4 in 2026. Micron is punching above its weight class with HBM3E, carving out market share by relying on domestic US manufacturing capacity and timing advantages, and directly clashing with SK hynix's expansion plans in the US. Additionally, SK hynix's capitalization path—featuring a record-breaking 26.5 billion USD fundraising and a market valuation briefly exceeding 1 trillion USD—has also put it in competition with Samsung and TSMC for pricing power over the AI narrative in the capital markets.
