Samsung's May 21 Strike: Experts Say Increased Delivery Uncertainty Will Weaken Competitiveness
In South Korea, labor negotiations at Samsung have broken down, leading the union to announce a full-scale strike starting May 21. Memory industry players analyze that this could drive up prices for DRAM and NAND Flash due to psychological effects. A semiconductor industry expert noted that while Samsung can cover short-term demand with inventory, a prolonged strike could impact the High-Bandwidth Memory (HBM) supply chain, affect AI server shipments, and weaken Samsung's foundry competitiveness due to increased delivery uncertainty. The actual impact will depend on the strike's participation rate and whether the South Korean government intervenes.

(CNA, by reporter Chang Chien-chung, Hsinchu, May 20) Labor-management negotiations at Samsung in South Korea have broken down, with the union announcing a full-scale strike to begin on the 21st. Memory industry analysts suggest that under the effect of market expectation, this could push memory prices higher. Meanwhile, a semiconductor industry expert believes the strike could increase uncertainty in Samsung's deliveries, thereby weakening its competitiveness.
Yonhap News Agency reported that South Korea's Central Labor Relations Commission proposed an adjustment plan to both Samsung's labor and management. The labor side accepted it, but management maintained a reserved stance. The union announced it would proceed with the full-scale strike on the 21st as planned.
Simon Chen, Chairman of memory module maker A-DATA, stated that Samsung is the global leader in Dynamic Random-Access Memory (DRAM) and NAND Flash. The strike will affect memory output, but the impact on the full year's output should be limited.
Chen said that driven by market expectation, DRAM and NAND Flash prices may continue to rise, but he hopes the increase will be moderate and that the Samsung strike will end soon.
Liu Pei-chen, Director of the TIER's database of industry and economic information, said that Samsung should be able to cover customer demand with inventory in the short term. However, with nearly 50,000 employees initiating a strike planned for up to 18 days, a prolonged duration could lead to delays in the high-bandwidth memory and semiconductor supply chains, thereby impacting AI server shipments.
Liu stated that the actual impact of the Samsung strike will depend on the union's bottom line for maintaining basic factory operations, the actual participation rate in the strike, and whether the South Korean government will intervene strongly by invoking its emergency mediation powers.
Liu analyzed that as the market anticipates the Samsung strike could widen the global memory supply gap, the psychological effect may further push up memory prices. Undeniably, the strike could increase the delivery uncertainty of Samsung's wafer foundry, potentially weakening its competitiveness at a time when the industry emphasizes supply chain resilience.
Sean Hsu, an analyst at market research firm TrendForce, pointed out that due to the high degree of automation in front-end wafer fabs, Samsung's DRAM and NAND Flash production is expected to continue operating at full capacity. The potential impact of the strike is likely to be concentrated in non-memory business units. (Editor: Lin Shu-yuan)
