SK Hynix reported a 556% year-on-year surge in operating profit for the second quarter of 2026, but the gain fell short of analyst expectations, sending the SKHY stock lower as investors weighed the semiconductor maker’s outlook against broader concerns about AI chip demand.
The South Korean memory chipmaker posted operating profit of 60.4 trillion won in Q2, up 61% from the previous quarter and 556% from the year-ago period, according to analyst Minsook Chae. However, the result missed the consensus forecast compiled by local brokerages by approximately 8%, with market expectations centered around 64.1 trillion won in operating profit.
SK Hynix’s earnings announcement on July 29, 2026, came less than three weeks after the company completed its historic U.S. debut on the Nasdaq, raising $26.5 billion in what was the largest-ever initial public offering by a foreign company. The strong Q2 profit reflected surging demand for high-bandwidth memory (HBM) chips used in artificial intelligence systems, which has driven record revenue and margins across the memory chip industry.
The stock decline despite the substantial profit growth reflects a pattern seen repeatedly across the semiconductor sector in 2026. Investors have grown concerned that the pace of AI infrastructure spending may not sustain the current level of chip demand, and guidance on future growth has become as important as current earnings. When Broadcom reported strong Q2 earnings in early June but kept its AI chip revenue guidance unchanged, shares dropped more than 12%, according to reporting from that period.
SK Hynix’s Q2 results represented a continuation of exceptional performance driven by AI demand. The company’s Q1 2026 operating profit had reached 37.6 trillion won, and HBM revenue more than doubled in 2025 as data centers raced to build out AI infrastructure. Revenue for Q2 was expected to reach approximately 84 trillion won, up significantly from prior quarters.
The timing of SK Hynix’s earnings, combined with volatility in the broader semiconductor index, underscored investor uncertainty about the longevity of the AI supercycle. The Philadelphia Semiconductor Index had fallen sharply in early July following disappointing guidance from Samsung and concerns about whether massive AI spending would justify the elevated valuations chip stocks have commanded. SK Hynix shares had pulled back 10% over the month leading up to the earnings report before a 14% rebound in the week before results, reflecting the high stakes investors attached to the announcement.
