[News] Samsung Reportedly Begins Preemptive Strike Measures on May 14, Shifts Product Mix Toward HBM
With Samsung’s major strike scheduled to begin on May 21, the memory giant has already moved to implement pre-emptive measures to limit potential losses. According to The Financial News and Newspim, the company is curbing the intake of new wafers into production lines while reshaping its product mix toward higher-value, cutting-edge nodes such as HBM.
Preemptive Production Cuts Begin Ahead of Strike
Notably, sources cited by The Financial News suggested that Samsung Electronics has begun implementing related measures such as “warm-down” production adjustments since May 14.
As explained by the report, “warm-down” refers to an emergency fab procedure used when production faces potential disruption, which involves pre-emptively reducing output and stabilizing equipment to minimize damage.
In semiconductor manufacturing, an abrupt shutdown can disrupt temperature and pressure balance inside tools, potentially resulting in wafer losses worth hundreds of billions of won, FN News reports, adding that the process therefore focuses on gradually cooling equipment or lowering operating rates rather than stopping abruptly.
HBM Takes Priority Amid Strike Risks
Among Samsung’s memory portfolio, leading-edge DRAM and HBM are emerging as top protection priorities. According to The Financial News, around 15,000 wafer storage pods were removed from dedicated logistics systems at DRAM lines in the company’s Pyeongtaek campus.
Separately, Newspim reports that Samsung Electronics is reshuffling production toward high-value chips such as HBM to cushion potential supply disruptions, as stable HBM output remains critical to maintaining global customer confidence amid surging AI demand.
EBN, on the other hand, highlights that that major customers including Apple and HP have already sought clarity on the potential impact of the strike, while HBM customers are closely monitoring the situation. Samsung, the report added, is actively reassuring clients that supply disruptions will be kept to a minimum.
Market Impact Comes Into Focus
Media reports differ on the scale of the strike’s impact. While some suggest overall financial damage may remain manageable, Money Today reports that a full shutdown of semiconductor production lines could lead to losses of up to 100 trillion won. An official cited in the report added that even if courts issue injunctions against illegal strike actions, losses could still reach 10–20 trillion won. The labor union, as per The Financial News, has also warned that an 18-day full strike could result in as much as 30 trillion won in losses, at roughly 1 trillion won per day.
On the other hand, an earlier Chosun Biz report estimated that even if memory production slows by as much as 5% based on wafer input levels, the effect on quarterly revenue would likely remain below 1 trillion won, compared with total quarterly sales of around 23 trillion won.
Notably, the Chosun Ilbo, citing analysts, notes that global memory supply disruptions are estimated to reach 3–4% for DRAM and 2–3% for NAND. While the figures appear relatively limited, experts cited by the report warned that under the current tight supply environment, even small disruptions could act as a key trigger for price increases.
At present, global DRAM inventories are understood to cover only around 4–6 weeks of demand, the report adds.
