STMicroelectronics Reports Declining Revenue Amid Automotive and Industrial Weakness

Q4 2024 Financial Performance

STMicroelectronics (ST) has released its Q4 2024 earnings report, revealing a 22.4% year-over-year decline in sales to $3.32 billion. The company’s gross margin dropped to 37.7%, while operating margin fell to 11.1%. Net income stood at $341 million, reflecting a 68.4% decline compared to the same quarter last year.

Full-Year 2024 Results

For the full fiscal year 2024, ST’s revenue totaled $13.27 billion, a 23.2% decrease year-over-year. The decline was primarily driven by weakness in the industrial and automotive sectors, which have faced slowing demand, particularly in Europe.

However, despite the downturn, STMicroelectronics made significant advancements in silicon carbide (SiC) technology, a key area of growth in the automotive semiconductor market. The company reported $1.1 billion in revenue from SiC sales and highlighted its fourth-generation SiC MOSFET technology as a major competitive strength. Additionally, ST signed long-term supply agreements with major automakers, including China's Geely.

2025 Q1 Outlook

Looking ahead to the first quarter of 2025, STMicroelectronics expects further declines, with:

Projected revenue of $2.51 billion (a 27.6% year-over-year decline and 24.4% quarter-over-quarter decline)

Gross margin expected to drop to 33.8%

Key Market Challenges & Strategic Initiatives

The downturn in STMicroelectronics' performance is largely attributed to sluggish demand in Europe’s automotive and industrial markets. However, the company remains proactive in expanding its partnerships and technological capabilities, particularly in China, where it is deepening collaborations with leading semiconductor manufacturers and automakers.

Expanding Localized Production in China

November 2024: ST announced a partnership with China’s second-largest foundry, Hua Hong Group, to manufacture 40nm MCUs in China by late 2025.

June 2023: ST partnered with San’an Optoelectronics to build a joint venture in Chongqing, China, for mass-producing 8-inch SiC devices. The SiC fab is expected to begin production in 2025, ramping up to full capacity by 2028, with a targeted output of 10,000 8-inch SiC wafers per week.

Silicon Carbide (SiC) Market Leadership

SiC technology remains a core focus for ST, as electric vehicles (EVs) and renewable energy systems drive increasing demand for high-efficiency power semiconductors.

The company's fourth-generation SiC MOSFETs provide a performance edge over competitors, reinforcing ST's position as a leading supplier in the power semiconductor market.

Conclusion

STMicroelectronics faces short-term challenges from weak demand in industrial and automotive sectors, but its investments in SiC technology and partnerships with Chinese firms position it for long-term growth. With China's semiconductor and EV industries booming, ST’s strategic moves could help it weather the downturn and capitalize on next-generation power semiconductor opportunities.
