SK hynix Inc. (NASDAQ: SKHY) delivered a decisive rebuttal to Wall Street’s bearish thesis on artificial intelligence memory demand, announcing record-breaking second-quarter financial results on July 28, 2026. The South Korean semiconductor giant reported revenues of 79.3187 trillion won and an operating profit of 60.5426 trillion won, marking a historic peak in profitability that invalidates recent market concerns about a structural slowdown in AI infrastructure spending. With shares having plunged nearly 47% since mid-July highs amid fears of Chinese competition and fading demand, the earnings data confirms that high-bandwidth memory (HBM) contracts remain robust and pricing power is intact.

The financial performance represents a dramatic acceleration from the prior period. Revenue surged 257% year-over-year from 22.232 trillion won in Q225 and grew 51% quarter-over-quarter from 52.5763 trillion won in Q126. Operating profit expanded even more sharply, rising 557% year-over-year and 61% quarter-over-quarter. The company achieved an unprecedented operating margin of 76%, up 35 percentage points from the same quarter last year. Net income reached 93.9226 trillion won, a 1,242% increase year-over-year, driven by strong sales of high-value-added products including HBM, DRAM for AI servers, and eSSD. Cumulative revenue for the first half of FY26 surpassed 100 trillion won for the first time in the company’s history.

Financial Performance And Balance Sheet Strength

SK hynix’s balance sheet strengthened significantly alongside its operational gains. Cash and cash equivalents rose to 88 trillion won at the end of the second quarter, an increase of 33.6 trillion won from the previous quarter. Total debt decreased by 0.7 trillion won to 18.6 trillion won, expanding the net cash position to 69.4 trillion won. Management stated that this liquidity provides significant financial flexibility to support mid-to-long-term growth opportunities while adhering to capital expenditure discipline.

Product Strategy And Long-Term Contracts

The record results were underpinned by sustained demand for advanced memory technologies. SK hynix began mass shipments of HBM4 in the second quarter, noting that the product achieved customer-required operating speeds with industry-leading power efficiency and cost competitiveness. The company plans to ramp up HBM4 production in the second half of the year. Additionally, sample shipments of HBM4E were completed in the first half, utilizing optimal processes focused on technology maturity and mass-production stability.

To secure supply stability, SK hynix finalized Long-Term Agreements (LTAs) with around 10 key customers, including major strategic partners. These multi-year contracts address structural demand growth as AI evolves into agentic forms performing complex tasks. In NAND flash, the company is accelerating its transition to advanced nodes, with 321-layer products now representing the largest share of total production. SK hynix aims to expand this capacity to approximately 50% of domestic production by year-end.

What The Numbers Show

The divergence between SK hynix’s stock performance and its operational reality highlights a severe mispricing by investors. While the share price declined nearly 47% on fears of demand destruction, physical export data and these earnings results confirm exceptional strength. The 76% operating margin demonstrates that SK hynix retains significant pricing power despite competitive pressures from Chinese manufacturers like ChangXin Memory Technologies. The surge in net cash to 69.4 trillion won further insulates the company from cyclical volatility, allowing it to fund upcoming investments such as the Yongin Phase 1 cleanroom opening in early 2027 and the P&T7 advanced packaging facility without compromising financial health.

SK Hynix Inc. (NASDAQ: SKHY) shares have plunged roughly 41% this month, marking their worst monthly performance since October 2008, as investors reassess valuations ahead of the company’s second-quarter earnings report on Wednesday, July 29. The sell-off, which accelerated Tuesday with a 14% drop in Seoul trading, reflects broader fears that Chinese capacity expansion could normalize memory prices and erode the pricing power that has driven recent profitability.

The market turmoil follows the blockbuster Shanghai debut of ChangXin Memory Technologies, whose shares soared more than 460% on their first day of trading. This event reignited concerns that China could rapidly expand DRAM production, triggering a broad selloff across global memory stocks including Micron Technology Inc., SanDisk Corp., and Samsung Electronics Co Ltd. Investors are now pricing in a future normalization of memory prices rather than relying on today’s record profitability levels.

Earnings Expectations vs. Market Sentiment

Despite the sharp correction, Wall Street expects SK Hynix to report robust second-quarter results, with revenue projected at $55.7 billion and earnings per share (EPS) at $4.79. These figures would represent a 243% year-over-year increase in revenue and a 604% surge in EPS, underscoring the continued strength of the AI-driven memory boom. For six consecutive quarters, SK Hynix has met or exceeded expectations, beating earnings estimates by nearly 50% last quarter and topping revenue consensus by more than $2.3 billion.

Recent Quarterly Performance

Structural Demand Remains Strong

The disconnect between the stock’s performance and fundamentals is striking. This week, Nvidia Corp. and South Korea’s SK Group unveiled a partnership tied to more than $500 billion of planned AI infrastructure investments. The initiative includes large-scale AI data centers and a strategic collaboration with SK Hynix on high-bandwidth memory (HBM). This reinforces the structural trend that AI models are becoming larger and inference workloads are rising, requiring more advanced memory for every new generation of Nvidia chips.

What the Numbers Show

The divergence between SK Hynix’s historical margin leadership and current investor skepticism highlights a shift from pure revenue growth to sustainability concerns. While the company has benefited from high demand for AI memory, the nearly 41% decline from peak levels suggests valuations were priced for perfection. The focus now shifts to whether management can convince investors that the AI buildout still has years—not quarters—left to run, despite near-term pressures from Chinese competition and potential margin compression.
