Samsung's large-scale strike strikes, shaking the global electronic component supply chain

Recently, Samsung Electronics' labor dispute has continued to escalate, and its union has overwhelmingly passed a strike resolution with 93.1% approval, planning an 18 day nationwide general strike from May 21 to June 7. This will be Samsung's largest labor capital confrontation since its establishment in 1969, and it has also raised widespread concerns in the global electronic components industry about supply chain stability. As a leading enterprise in the global electronic components field, Samsung's production capacity fluctuations are rapidly spreading throughout the entire industry chain, from storage chips to display panels, from terminal manufacturing to downstream fields such as AI and automotive electronics, all of which are being impacted to varying degrees.

The root cause of this conflict lies in the unfair distribution of bonuses. Samsung's performance is currently at its historical peak - operating profit of approximately KRW 20 trillion in the fourth quarter of 2025, breaking a single quarter record, and storage business revenue surged 61.3% driven by AI demand. But the union believes that employees have not been able to share in the company's dividends, and their core demands include abolishing the 50% upper limit on OPI bonuses, achieving transparency in performance bonuses, and increasing basic wages by 7%. The trigger was that competitor SK Hynix had lifted the bonus cap and promised to allocate 10% of its operating profit for dividends. Over the past three months, more than 100 Samsung employees have switched jobs to SK Hynix. Samsung's management had proposed plans such as increasing salaries by 6.2% and issuing 20 shares of company stock, but the union believed that these did not address the core of fair distribution. After unsuccessful negotiations, the strike entered the countdown.

From the perspective of industry impact, as a core supplier of global electronic components, Samsung's production capacity interruption will directly exacerbate the global supply-demand imbalance, with the storage chip sector being the first to bear the brunt. Data shows that Samsung has a market share of over 41%, 34%, and 45% in the global DRAM, NAND flash, and HBM memory markets, respectively. The strike will directly affect the two core production bases of Pingze and Huacheng, with an expected 50% reduction in production capacity, equivalent to a reduction of nearly 30% and 35% in global memory and NAND flash memory supply, respectively. Due to the abnormal shutdown of semiconductor production lines, the longest restart cycle can reach 2 months. The 18 day strike is expected to cause direct economic losses exceeding 9 trillion Korean won (approximately 48 billion yuan).

The tight supply has quickly spread to the price side. The current global storage market is already in short supply, and the news of strikes has further pushed up prices. The cumulative increase of DDR4 8Gb chips has reached 369%, and the six-month increase of 16GB DDR5 memory has exceeded 500%. Jibang Consulting warns that if the strike is implemented, the DRAM contract price will increase by another 10% -15% in the second quarter. If production capacity is not restored in the third quarter, the increase may expand to more than 20%, which will directly push up the production costs of downstream enterprises. In addition to storage chips, Samsung's OLED business (with a global market share of over 60%), wafer foundry (with 2nm production capacity), CIS image sensors (second largest global market share) and other businesses have all been affected, which may lead to chain problems such as delayed order delivery and hindered product iteration for downstream enterprises in the fields of mobile phones, in car displays, chip design, etc.

At present, the chain reaction of downstream terminal industries has gradually emerged. In the field of consumer electronics, the cost of memory and flash memory has increased from 15% to 30% of the total cost of smartphones and PCs. Some mid to low end models are facing pressure to increase prices or reduce production, and some brands have announced the suspension of mass production of low-priced models. The DIY hardware market is experiencing a situation where "one item is hard to find" and channel merchants are hoarding their goods. In the field of AI and servers, there is already a 4-fold capacity gap in HBM memory, and Samsung's strike will further delay the progress of data center construction, dragging down the deployment pace of global AI computing power. In the field of automotive electronics, the tight supply of automotive grade storage has led to extended delivery cycles for car companies, and some intelligent vehicle models are facing the risk of reduced configurations. It is worth noting that China's dependence on memory imports still exceeds 70%, and fluctuations in the global supply chain will be directly transmitted to domestic consumption and industrial markets, driving up production costs for enterprises and living costs for residents.

This strike has also brought new variables to the global electronic component supply chain pattern, and domestic substitution has entered a critical window period. As Samsung's production capacity is limited, top global brands have begun to diversify their procurement and accelerate the introduction of non Korean storage chips. The order volume of domestic manufacturers such as Changjiang Storage and Changxin Storage has increased by more than 40% month on month, and some customers have signed long-term agreements for 1-3 years in advance, which has steadily increased the market share of domestic storage chips. However, industry insiders also pointed out that the market share of domestic storage in high-end DDR5, automotive grade, and enterprise grade markets is still less than 15%. The HBM field has not yet achieved large-scale production, and it is difficult to completely replace Samsung's production capacity in the short term. The overall gap in the supply chain will continue. At present, both labor and management have agreed to restart negotiations, and Samsung has promised to include the union's relevant demands in the agenda, but the union still reserves the possibility of a strike. The industry generally believes that this incident highlights the risk of excessive concentration in the supply chain, which will drive downstream enterprises to accelerate the diversification of their supply chain layout, while also forcing domestic electronic component companies to accelerate their pace of technological breakthroughs.
