Key Highlights
- First-quarter net earnings reached 40.3 trillion won ($27.2B), marking a nearly 400% increase compared to the same period last year
- Quarterly sales exceeded 50 trillion won for the first time ever, falling slightly below Wall Street expectations
- Operating profitability soared to an unprecedented 72%, with operating earnings almost doubling versus Q4 2025
- The semiconductor manufacturer commands 57% of the global HBM market and expects to distribute next-generation HBM4E samples in late 2026
- A 19 trillion won investment in a new domestic production facility underscores efforts to meet explosive AI chip demand
SK Hynix delivered exceptional performance in the opening quarter of 2026. The memory chip giant from South Korea unveiled its most profitable three-month period ever on Thursday, propelled by skyrocketing valuations for artificial intelligence memory semiconductors.
Quarterly net earnings reached 40.3 trillion won ($27.2 billion), significantly surpassing analyst projections of 29.4 trillion won. Sales totaled 52.58 trillion won — marginally below the consensus estimate of 53.55 trillion won, yet representing nearly triple the figure from twelve months prior.
Operating earnings climbed fivefold year-over-year and approached double the preceding quarter’s figure. The operating margin touched 72%, establishing a new company benchmark.
Shares climbed up to 3.6% during morning trading in Seoul before moderating to close down 0.9%.
The chipmaker attributed these exceptional figures to elevated memory pricing and intensifying requirements from artificial intelligence infrastructure expansion. Although the first quarter typically experiences seasonal softness, the organization noted sustained momentum in customer orders.
“Robust demand continued as companies expanded their AI infrastructure investments,” the firm stated in its quarterly announcement.
High-Bandwidth Memory Leadership Fuels Growth
SK Hynix maintains its position as the global leader in high-bandwidth memory production, an essential element for AI server systems. The company controls 57% of the worldwide HBM marketplace and serves as a principal vendor to Nvidia.
HBM requirements have proven so intense that manufacturing capacity has become limited, simultaneously driving up valuations for standard DRAM products. The broader DRAM sector experienced 30% sequential growth for two consecutive quarters, based on Counterpoint Research findings.
The firm’s DRAM marketing executive suggested that the favorable pricing environment might prove “more sustained than in previous cycles,” given manufacturers’ challenges in matching demand levels.
Samsung regained the leading position in total DRAM sales from SK Hynix during Q4 2025, according to Counterpoint intelligence. However, SK Hynix has preserved its dominance in the higher-margin HBM category.
Samsung revealed in February that it had begun distributing its initial HBM4 products. SK Hynix had already provided HBM4 prototypes nearly twelve months earlier, and Thursday’s announcement confirmed plans to deliver seventh-generation HBM4E samples during the latter half of 2026, with volume manufacturing scheduled for 2027.
Manufacturing Expansion and Supply Chain Strategy
The semiconductor producer revealed intentions to allocate 19 trillion won toward a new production complex in Cheongju, South Korea.
SK Group’s Chairman Chey Tae-won has indicated that the worldwide chip wafer supply constraint may extend until 2030, given that capacity additions require four to five years to become operational and the anticipated deficit could surpass 20%.
Regarding supply chain vulnerabilities, the continuing Middle Eastern tensions have generated concerns about procurement of materials including helium, bromine, and tungsten. SK Hynix confirmed it has broadened its vendor network and accumulated adequate reserves, anticipating minimal manufacturing disruption.
Extended liquefied natural gas contracts have also been secured to mitigate energy price volatility.
Counterpoint Research analyst MS Hwang informed CNBC that first-quarter performance from memory manufacturers “demonstrates impressive profitability and indicates that AI inference requires substantially more memory than previously anticipated.”
Mirae Asset Securities analyst Kim Young-gun projected that SK Hynix’s financial performance will maintain strength throughout 2026, citing multi-year procurement agreements being finalized with prominent technology firms — several of which are already requesting contract extensions beyond original timeframes.
