STMicro Beats Q1 2023 Earnings Expectations Despite Chip Shortages

  • STMicro expects 2023 revenue of $17.0 billion-$17.8 billion, representing a 5%-10% growth over 2022.
  • Silicon carbide (SiC) substrate manufacturing facility in Catania will fulfill the continuing demand as Silicon Carbide (SiC) in EVs is growing substantially.
  • In 2023, revenue from SiC is expected to be around $1.2 billion, with a significant portion of its substrates internally sourced by 2024.

STMicro’s Q1 2023 net revenue rose 19.8% YoY to reach $4.25 billion, primarily driven by strong demand from the automotive and industrial segments and partially offset by lower revenue in personal electronics. Revenue from factory automation, robotics and building control grew while new orders normalized. STMicro will have a significant portion of its substrates internally sourced by 2024 as it continues to ramp up silicon carbide front-end device production in its Singapore facility. The company’s gross margin improved to 300bps YoY and 220 bps QoQ in Q1 2023 driven by favorable pricing and improved product mix, net of hedging, but was partially offset by an increase in manufacturing input costs.

STMicro Beats Q1 2023 Earnings Expectations Despite Chip Shortages
