UMC Demands 15% Price Cut from Suppliers: A Strategy for Cost Control

2025-10-11

In October 2025, United Microelectronics Corporation (UMC), one of the world's leading pure-play foundries specializing in mature process technologies, issued a notice to its upstream suppliers, demanding a price reduction of at least 15% on all supply items effective from January 1, 2026. UMC emphasized that only through comprehensive cost reduction measures can the company and its supply chain maintain their competitive edge.

Background and Reasons for the Price Reduction

UMC Demands 15% Price Cut from Suppliers: A Strategy for Cost Control

As a global leader in pure mature process foundry services, UMC's actions are often seen as indicative of industry trends. Currently, the global semiconductor market is highly competitive, especially in the mature process segment. On one hand, after inventory adjustments, demand in consumer electronics, industrial electronics, and automotive electronics has yet to show significant recovery. On the other hand, the continuous expansion of mature process capacities has led to a tightening supply-demand relationship. For example, Chinese foundries such as SMIC, Huahong, and Taiwan-based PSMC have been expanding their 28-90nm mature process capacities, exacerbating the oversupply situation. Moreover, geopolitical and economic conditions have driven up energy, raw material, and logistics costs, and intensified market competition, posing severe challenges to UMC's operations and competitiveness.

Looking at UMC's financial status, its gross margin for the first half of 2025 was 27.72%, nearly halved compared to 45.12% in 2022. In 2026, the commissioning of UMC's new factory in Singapore will further increase depreciation costs. Under these circumstances, optimizing costs to maintain global competitiveness has become an inevitable choice for UMC.

Specifics of the Price Reduction Demand

This price reduction demand mainly involves key consumables in semiconductor manufacturing, such as silicon wafers, photomasks, and special gases. UMC has asked suppliers to respond with specific adjustment plans within one month of receiving the notice, with a reduction of at least 15%, and the plan must cover the year 2026. UMC has also made it clear that this price reduction plan will be an important basis for future cooperation and capacity allocation. This means that suppliers' responses to the price reduction will directly affect UMC's cooperation priority and resource allocation.

Industry Impact and Reactions

UMC's large-scale push for supply chain price reductions may signal the beginning of a new round of price competition in the industry. Thousands of supply chain vendors may be affected. In the short term, this may put some pressure on suppliers' profits; but in the long term, it may also prompt suppliers to improve efficiency and reduce costs to maintain competitiveness.

The industry has mixed views on UMC's move. On one hand, some believe that UMC's control of upstream costs to maintain gross margins is a normal operation. Its bargaining power may come from the sufficient competition among some material suppliers, and industry leaders also have similar cost requirements. For example, TSMC requires suppliers to reduce prices by about 5% every year. On the other hand, some argue that UMC's strong stance and large reduction demand are related to the low-price orders from Chinese mainland mature processes. In addition, some also believe that UMC's move may accelerate the reshuffling of the supply chain and even trigger a wave of price cuts.

Conclusion

UMC's demand for a 15% price reduction from suppliers is a strategic choice under current market competition and its own financial pressure. By promoting cost reduction measures, UMC hopes to maintain the competitive advantage of the company and its supply chain, and prepare in advance for the new round of adjustments in the mature process market. However, this move may also have a profound impact on the industry and trigger a series of chain reactions. In the future, cooperation between UMC and suppliers will be more closely focused on cost control and competitiveness enhancement, and the entire semiconductor industry will continue to pay attention to the subsequent development of this event.
