UMC joins the chip price hike trend; prices will increase starting in the second half of 2026, and clients have "nowhere to go."

```

United Microelectronics Corporation (UMC) announced an increase in wafer foundry prices, becoming another major foundry to join the price hike wave after leading players such as TSMC. With demand continuing to outpace supply in the market, this round of semiconductor foundry price increases is spreading throughout the industry chain.

According to a letter from UMC to customers, the company will officially implement wafer price adjustments in the second half of 2026.

UMC attributed the price increase to the ongoing rise in costs for raw materials, energy, logistics, and the procurement of key manufacturing equipment, emphasizing that this move aims to further enhance manufacturing efficiency and ensure high-quality wafer supply for customers.

This price adjustment notice affects a wide range of customers. UMC's major clients include MediaTek, Intel, Qualcomm, Broadcom, Realtek, Novatek, Texas Instruments, and many medium and small chip companies. For these customers, accepting the price hike is almost the only option, given the general tightness in global wafer foundry capacity.

Price Increase Logic: Rising Costs and Exploding Demand

UMC listed multiple driving factors for this price adjustment in its statement. The continued rise of raw materials, energy, and logistics prices directly increases foundry costs, while procurement expenses for critical manufacturing equipment have also grown substantially.

At the same time, robust growth on the demand side further supports the price increase. UMC pointed out that demand in communications, industrial, artificial intelligence, and consumer electronics sectors is expanding across the board.

The surge in AI demand is especially critical—this trend has permeated the entire technology industry, leading to global supply chain shortages and triggering chain reaction price hikes in the chip foundry sector.

Industry Position: The World's Fourth Largest Wafer Foundry

Currently, UMC ranks 42nd globally by market capitalization and, in the wafer foundry segment, follows TSMC, Samsung, GlobalFoundries, and SMIC, making it one of the world's fifth largest wafer foundries.

Although UMC's deployment in advanced manufacturing processes is less aggressive than TSMC's, its solid market position in mature processes makes it a critical capacity provider for communications, industrial, and consumer electronics chip designers.

This price hike shows that the supply and demand tension in mature process capacity cannot be ignored either.

Industry Impact: Cost Pressure Cascades Downstream

UMC’s decision to raise prices indicates that the global wave of wafer foundry price hikes is no longer limited to top players like TSMC, but is becoming common across the major foundry tier.

For customers like MediaTek, Qualcomm, and Broadcom, rising foundry costs will directly compress their chip business profit margins, and may ultimately be passed on to end product prices.

UMC stated in its announcement that it will continue working with partners to jointly address the structural evolution of the global semiconductor landscape. However, given the current supply and demand situation in the market, customers have extremely limited alternatives available in the short term.
