Key Takeaways:
- Samsung record profit is projected to jump 19-fold operating profit jump for the second quarter.
- High demand for artificial intelligence memory chips fueled the historic earnings surge.
- Shares fell sharply as investors feared the semiconductor boom had peaked.
Samsung Electronics reported preliminary second-quarter operating profit that surged more than 19-fold on strong AI memory demand, but shares of Samsung and other memory-chip makers fell as investors questioned whether the industry’s earnings have reached a peak.
Samsung Posts Record Quarterly Profit
Samsung Electronics said it expects second-quarter operating profit of about 89.4 trillion won (about $58 billion), up more than 19 times from the same period a year earlier. The company also forecast revenue of about 171 trillion won, a 129% increase year over year.
The preliminary results mark Samsung’s strongest quarterly performance on record, driven by soaring demand for high-bandwidth memory (HBM) chips and high-capacity DRAM used in artificial intelligence servers.
Despite the strong results, Samsung shares fell more than 10% during trading in Seoul. The decline spread across the memory sector, with shares of Micron Technology, Western Digital and SanDisk also posting sharp losses.
Investors Focus on Valuations, Not Results
Market analysts said the sell-off reflected expectations that had already been priced into semiconductor stocks after months of strong gains fueled by AI demand.
Micron shares have risen about 242% in 2026, supported by record financial results. For its fiscal third quarter ended May 28, the company reported revenue of $41.5 billion, up 346% from a year earlier, with adjusted earnings per share of $25.11 and a non-GAAP gross margin of 84.9%.
Micron also projected fiscal fourth-quarter revenue of about $50 billion and adjusted earnings per share of roughly $31.
“Micron’s record fiscal Q3 financial results and even stronger outlook for Q4 reflect the strategic value of memory in the AI era,” Micron President and Chief Executive Officer Sanjay Mehrotra said in the company’s earnings release.
Investors, however, appeared to view Samsung record profit as confirmation of expectations rather than a positive surprise. The market reaction suggested traders are becoming more cautious after the sector’s rapid gains.
Markets Debate Sustainability of Memory Boom
The sell-off also reflects concerns that the memory-chip industry may be approaching the most profitable stage of its current cycle.
The semiconductor memory business has historically experienced sharp swings as supply and demand shift. Analysts note that periods of exceptionally high profits have often been followed by declining prices and weaker earnings once production catches up with demand.
Micron has acknowledged the cyclical nature of the business but maintains that demand remains strong. The company said it expects tight supply conditions for DRAM and NAND memory products to continue beyond 2027.
Samsung record profit reinforces the strength of AI-driven memory demand, but investors remain focused on how long that momentum can last. Rising investment in AI infrastructure continues to support demand for advanced memory chips, although markets appear increasingly concerned about future growth rates rather than current results.
The decline in semiconductor stocks highlights a broader shift in investor sentiment, where Samsung record profit and record earnings alone may no longer be enough to drive share prices higher if expectations have already been fully reflected in market valuations.
