Samsung Electronics' largest union in South Korea warned that chip production could be disrupted if members approve the plan in a strike vote in May. As the world's largest memory chip maker, a strike at Samsung could exacerbate global semiconductor supply bottlenecks. Choi Seung-ho, chairman of the Samsung Electronics Labor Union (SELU), said at the launch of the vote last week: "I expect there will be production disruptions." The vote will continue through Wednesday. Choi Seung-ho said that if labor and management fail to reach an agreement, the union is expected to hold an 18-day strike starting May 21, which could affect about half of the production at the massive semiconductor complex in Pyeongtaek, south of Seoul. The Samsung union is demanding a 7% raise in base pay, the removal of the performance-based compensation cap, currently set at 50% of annual base salary, and the introduction of a bonus pool based on operating profit.

Following memory and packaging, a new wave of price hikes swept through the semiconductor industry chain. Mature-process wafer foundries in Taiwan, including UMC, Vanguard, and PSMC, were reported to raise quotations as early as April, by as much as 10 or even more. Major users of mature processes—IC design houses led by driver IC makers—were also expected to raise prices in response to rising costs. UMC did not comment on market rumors of price hikes, but the company had previously said that the current pricing environment was "indeed more favorable than before." In a notice, Vanguard said it planned to adjust toll processing prices starting in April 2026, but did not disclose the size of the increase. PSMC confirmed that it had gradually raised prices since the current quarter, mainly for product lines with lower gross margins.
