    • “In Q4, ST delivered revenues and gross margin slightly below the mid-point of the guidance, with higher revenues in Personal Electronics offset by a softer growth rate in Automotive.”
    • “In Q4, our customer order bookings decreased compared to Q3. We continued to see stable end-demand in Automotive, no significant increase in Personal Electronics, and further deterioration in Industrial.”
    • “Our first quarter business outlook, at the mid-point, is for net revenues of $3.6 billion, decreasing year-over-year by 15.2% and decreasing sequentially by 15.9%; gross margin is expected to be about 42.3%.”
    • “For 2024, we plan to invest about $2.5 billion in net CAPEX.”
    • “We will drive the Company based on a plan for FY24 revenues in the range of $15.9 billion to $16.9 billion. Within this plan, we expect a gross margin in the low to mid-40’s.”
