Samsung Electronics reported a preliminary second-quarter operating profit of 89.4 trillion won, equivalent to approximately $58.4 billion, an over 19-fold surge compared to the same period a year earlier that set a new all-time corporate record. The figure beat the LSEG SmartEstimate of 87.3 trillion won and surpassed Samsung's combined operating profit over the entire three-year period from 2023 through 2025. Quarterly revenue came in at 171 trillion won, a 129.3% year-over-year increase that nonetheless fell short of analyst forecasts ranging from 172.2 trillion to 173.3 trillion won.
Despite the historic profit figure, Samsung shares fell as much as 6.8% in Seoul trading, with the broader KOSPI declining 4.2% and briefly triggering a circuit breaker that paused trading for 20 minutes after the index fell more than 8% at session lows. The selloff reflected the gap between what was reported and what some of the most bullish traders had expected. Several analysts had modeled operating profit exceeding 90 trillion to 100 trillion won even after accounting for significant bonus-related provisions for semiconductor workers, provisions that were locked in under a May 2026 wage agreement tying employee pay to operating profit. Without those provisions, analysts estimated Samsung's profit would have exceeded 100 trillion won.
The earnings surge was driven almost entirely by memory chips. DRAM and NAND prices continued to climb during the quarter as AI infrastructure spending broadened from high-bandwidth memory into conventional memory products used across a wider range of server and PC applications. Samsung did not provide a divisional breakdown in its preliminary filing; the full earnings release is scheduled for July 30, at which point investors will be able to assess HBM revenue trends and the degree to which Samsung is regaining ground against SK Hynix in the most profitable tier of the memory market.
The revenue miss and the perception that profit guidance was set artificially low by bonus accounting pressured memory-sector peers in US premarket trading. Micron Technology fell more than 4% and SanDisk also slid more than 4% before the open, with broader semiconductor names including Marvell Technology, Broadcom, KLA, and AMD also declining. The VanEck Semiconductor ETF slid more than 3% as the AI memory trade unwound modestly after a period of outsized gains.
Analysts said the longer-term picture remains intact, even if Tuesday's reaction punished the sector for missing elevated expectations. The memory chip shortage is expected to deepen in the second half of 2026 and into 2027, with analysts at KB Securities saying Samsung's profit will continue to grow sequentially. The key debate is how sharply sequential growth accelerates, and whether Samsung can close the HBM quality gap with SK Hynix to capture a greater share of the highest-margin AI memory contracts.
Samsung's full-year 2026 operating profit consensus sits around 300 trillion won, roughly $200 billion, a figure Samsung management has said it expects to meet. If achieved, it would represent the largest full-year corporate profit ever recorded in Korea and one of the largest in global semiconductor history. The company's shares have risen approximately fivefold over the past year, leaving the stock vulnerable to pullbacks when results, however historically strong, fall short of the market's high bar.
