STMicroelectronics N.V., a global semiconductor leader serving customers across the spectrum of electronics applications, reported U.S. GAAP financial results for the first quarter ended March 30, 2024. This press release also contains non-U.S. GAAP measures (see Appendix for additional information).

ST reported first quarter net revenues of $3.47 billion, gross margin of 41.7%, operating margin of 15.9%, and net income of $513 million or $0.54 diluted earnings per share.

Jean-Marc Chery, ST President & CEO, commented:

·       “Q1 net revenues and gross margin both came in below the midpoint of our business outlook range, driven by lower revenues in Automotive and Industrial, partially offset by higher revenues in Personal Electronics.”

·       “On a year-over-year basis, Q1 net revenues decreased 18.4%, operating margin decreased to 15.9% from 28.3% and net income decreased 50.9% to $513 million.”

·       “During the quarter, Automotive semiconductor demand slowed down compared to our expectations, entering a deceleration phase, while the ongoing Industrial correction accelerated.”

·       “Our second quarter business outlook, at the mid-point, is for net revenues of $3.2 billion, decreasing year-over-year by 26.0% and decreasing sequentially by 7.6%; gross margin is expected to be about 40%.”

·       “We will now drive the Company based on a revised plan for FY24 revenues in the range of $14 billion to $15 billion. Within this plan, we expect a gross margin in the low 40’s.”

·       “We plan to maintain our Net Capex1 plan for FY24 at about $2.5 billion focusing on our strategic manufacturing initiatives.”

Total Net Revenues3,4654,2824,247-19.1%-18.4%

Net revenues totaled $3.47 billion, representing a year-over-year decrease of 18.4%. Year-over-year net sales to OEMs and Distribution decreased 11.5% and 30.8%, respectively. On a sequential basis, net revenues decreased 19.1%, 320 basis points lower than the mid-point of ST’s guidance.

Gross profit totaled $1.44 billion, representing a year-over-year decrease of 31.6%. Gross margin of 41.7%, 60 basis points below the mid-point of ST’s guidance, decreased 800 basis points year-over-year, mainly due to the combination of sales price and product mix, unused capacity charges and reduced manufacturing efficiencies.

Operating income decreased 54.1% to $551 million, compared to $1.20 billion in the year-ago quarter. ST’s operating margin decreased 1,240 basis points on a year-over-year basis to 15.9% of net revenues, compared to 28.3% in the first quarter of 2023.

By reportable segment, compared with the year-ago quarter:

In Analog, Power & Discrete, MEMS and Sensors (APMS) Product Group:

Analog products, MEMS and Sensors (AM&S) segment:

  • Revenue decreased 13.1% mainly due to a decrease in MEMS and Imaging.  
  • Operating profit decreased by 44.8% to $185 million. Operating margin was 15.2% compared to 23.9%.

Power and Discrete products (P&D) segment:

  • Revenue decreased 9.8% mainly due to a decrease in Discrete.
  • Operating profit decreased by 41.6% to $138 million. Operating margin was 16.8% compared to 26.0%.

In Microcontrollers, Digital ICs and RF products (MDRF) Product Group:

Microcontrollers (MCU) segment:

  • Revenue decreased 34.4% mainly due to a decrease in GP MCU. 
  • Operating profit decreased by 66.7% to $185 million. Operating margin was 19.5% compared to 38.3%.

Digital ICs and RF products (D&RF) segment:

  • Revenue decreased 2.1% due to a decrease in ADAS more than offsetting an increase in RF Communications.
  • Operating profit decreased by 8.2% to $150 million. Operating margin was 31.8% compared to 33.9%.

Net income and diluted Earnings Per Share decreased to $513 million and $0.54 respectively compared to $1.04 billion and $1.10 respectively in the year-ago quarter.
