Chipmakers Face Slower Automotive Demand in Q1 2025

Wolfspeed

Semiconductor Firms Anticipate Declining Auto Sales, With EV Growth Concentrated in China

Semiconductor companies like STMicroelectronics, Wolfspeed, and NXP are bracing for slower demand growth from the automotive sector in the first quarter of 2025. This reflects a broader decline in vehicle production outside of China, where the electric vehicle (EV) market continues to outpace the rest of the world.

Declining Automotive Demand and Growing EV Shift in China

NXP, based in the Netherlands, reported a 4% drop in its automotive revenue for 2024. This decline was attributed to "inventory digestion at western tier 1 customers" amid an uncertain automotive demand environment. The company expects further declines in automotive revenue for the first quarter of 2025. However, NXP’s revenue from China grew by 4%, highlighting an increase in semiconductor content in vehicles as Chinese automakers embrace electrification and software-defined architectures.

NXP's strategy for China, which it calls "China for China," involves producing devices at its Tianjin plant for sale to the Chinese market. According to NXP president and CEO Kurt Sievers, the growth is natural and structurally ongoing, especially in China where 50% of cars sold in the second half of 2024 were electric or hybrid. This rapid transition to EVs in China is fueling an above-average increase in the semiconductor content of vehicles.

STMicroelectronics, based in Switzerland, faces similar challenges and is prioritizing the transition from 150mm wafers to 200mm wafers, driven by demand for silicon carbide (SiC) semiconductors. SiC devices are crucial for the automotive sector, particularly for EVs. The company plans to start 200mm SiC semiconductor wafer production at its Shenzhen plant in the first half of 2026. STMicro reported that 2024 was one of the worst years in decades, with weaker demand in both the automotive and industrial sectors and a higher level of inventories.

In response to growing demand, STMicro is building a new facility in Catania, Italy, to supply western markets. Silicon carbide manufacturers are making the transition to 200mm to produce more devices per wafer, a move driven by increasing demand from the automotive sector. However, the industrial and energy (I&E) sector continues to show low semiconductor demand, forcing companies like STMicro to focus more on automotive sales.

Wolfspeed's Shift to Automotive and Growing Market Opportunities

Wolfspeed, a US-based company that has pivoted to focus on SiC wafers and devices, has seen its product mix shift from industrial and energy (I&E) applications to automotive. Wolfspeed is shifting production from its 150mm plant in Durham, North Carolina, to its new 200mm plant in Mohawk Valley, New York. The company expects its revenue split to shift to 70% automotive and 30% I&E as the transition progresses. Despite the shift, Wolfspeed acknowledges the slower-than-expected adoption of EVs, which has contributed to a weaker market environment for EV semiconductors.

Despite these challenges, Wolfspeed is well-positioned as a first mover in the 200mm transition and expects its automotive revenues to grow through a broad customer base. SiC demand from I&E applications is beginning to show signs of recovery, but visibility into the coming quarters remains uncertain.

The automotive sector continues to be a primary focus for semiconductor firms as demand from the industrial and energy sectors remains weak. With the increasing push for electrification, semiconductor companies are recalibrating their strategies, focusing on innovations like SiC wafer production and ramping up investments in manufacturing capacity to meet growing automotive demand.
