Silicon carbide revenue for 2024 reached $1.1 billion, falling short of the initial $1.3 billion target due to shifts in the EV market. Despite these headwinds, STMicroelectronics maintained a solid net financial position of $2.67 billion as of June 28, 2025, supported by total liquidity of $5.63 billion. The company also continued its share repurchase program, buying back 271,723 ordinary shares for EUR 6.36 million in late August 2025.

Strategic Outlook and Growth Catalysts

STMicroelectronics' outlook for the remainder of 2025 and beyond is one of cautious optimism, underpinned by strategic initiatives and an anticipated market recovery. For Q3 2025, the company forecasts revenues of $3.17 billion (midpoint), representing a 14.6% sequential increase and a 2.5% year-over-year decrease. Crucially, all end markets except Automotive are expected to return to year-on-year growth. The Q3 gross margin is projected at 33.5%, impacted by approximately 340 basis points of unused capacity charges and about 20% of a 140 basis point negative sequential impact from manufacturing reshaping costs.

Management anticipates a "nice improvement" in gross margin for Q4 2025 compared to Q3, driven by reduced unused capacity charges and enhanced manufacturing efficiency. This improvement is contingent on the euro-dollar exchange rate remaining around $1.17. The company expects sequential revenue growth in Q4 2025, potentially leading to year-over-year growth for the entire company.

The company's strategic initiatives are designed to capitalize on long-term secular trends. The manufacturing footprint reshaping program, with a planned net CapEx of $2 billion to $2.3 billion for 2025, is critical.
