STMicroelectronics N.V. (ISIN NL0000226223) reported a clear slowdown at the start of 2024, with investors in STMicroelectronics stock focusing on how the company manages a downturn in some end markets against a still sizable automotive and industrial pipeline. According to the companys first-quarter 2024 earnings release dated 25 April 2024, net revenues fell to $3.47 billion from $4.25 billion a year earlier, a decline of 18.4%. The same filing shows that the operating margin narrowed to 16.5% in Q1 2024 compared with 25.1% in Q1 2023 as lower volumes and product mix weighed on profitability.
Revenue down 18.4 percent in Q1 2024
In its Q1 2024 report published on 25 April 2024, STMicroelectronics stated that net revenues of $3.47 billion were down 18.4% year on year from $4.25 billion, driven by softer demand in personal electronics and some industrial applications. Management also highlighted that the analog, MEMS and sensors segment saw pressure, while automotive and power discrete remained relatively more resilient within the portfolio. The same document indicates that gross profit came in at $1.36 billion in Q1 2024, compared with $1.92 billion in the prior-year quarter, translating into a gross margin of 39.3% versus 45.2% a year earlier as underloading of manufacturing capacity reduced fixed-cost absorption.
Net income showed an even steeper decline in the first quarter. According to the Q1 2024 earnings materials, STMicroelectronics generated net income of $513 million in Q1 2024, down from $1.04 billion in Q1 2023, which corresponds to a drop of roughly 50.7% year on year. Diluted earnings per share for the period were $0.54, compared with $1.10 in the prior-year quarter, underscoring how the cyclical downturn and normalization after exceptionally strong 2023 conditions are feeding through to the bottom line. For investors, this profit contraction is a key factor in assessing whether current valuation reflects mid-cycle or peak-cycle earnings.
Full-year 2024 outlook cut versus 2023 peak
Alongside the first-quarter numbers, STMicroelectronics updated its guidance for the full-year 2024. In commentary released with the Q1 2024 results on 25 April 2024, the group guided for full-year 2024 net revenues of around $14.8 billion at the midpoint, compared with the $17.29 billion reported for full-year 2023. That implies an expected decline of roughly 14.4% in annual sales versus 2023 as the company anticipates weaker conditions in some end markets before a recovery in 2025. Management also communicated a planned full-year 2024 gross margin of around 40% at the midpoint, versus the 45.6% gross margin recorded in 2023, reflecting continued cost inflation and less favorable pricing in some product areas.
The companys reported 2023 figures show the scale of the comparison. In its full-year 2023 financial statements, STMicroelectronics disclosed net revenues of $17.29 billion, up from $16.13 billion in 2022, an increase of about 7.2% year on year. Operating income in 2023 reached $4.24 billion, up from $4.05 billion in 2022, but operating margin slipped slightly from 25.1% to 24.5% as higher research and development spending and capacity investments partly offset volume growth. For shareholders analyzing STMicroelectronics stock, this shift from mid-single-digit revenue growth in 2023 to a projected mid-teens decline in 2024 illustrates how cyclical the broader semiconductor demand picture remains despite structural drivers such as automotive electrification and industrial automation.
Cash generation is another key data point for the 2023-2024 transition. According to the 2023 annual results, STMicroelectronics reported net cash from operating activities of $6.06 billion for 2023, compared with $6.28 billion in 2022, while free cash flow before acquisitions came in at $1.17 billion in 2023 versus $1.59 billion in 2022. The decrease in free cash flow reflects rising capital expenditures as the company expands its 300-millimeter manufacturing footprint and increases capacity for silicon carbide power devices. In its 2024 outlook, management continues to foresee capital expenditures in the range of $3.5 billion to $3.8 billion, similar to the $4.26 billion invested in 2023, signaling an ongoing commitment to long-term capacity even as near-term demand softens.
Automotive and power segments underpin long-term thesis
STMicroelectronics has increasingly oriented its portfolio toward automotive and industrial applications, and those segments are central to how many investors evaluate the medium-term potential of STMicroelectronics stock. In the companys 2023 segment disclosure, the Automotive and Discrete Group generated $7.45 billion of net revenues, up from $6.07 billion in 2022, an increase of roughly 22.7% year on year, driven by demand for microcontrollers and power semiconductors in electric vehicles and advanced driver-assistance systems. Over the same period, the Microcontrollers and Digital ICs Group produced net revenues of $5.77 billion, compared with $5.29 billion in 2022, while the Analog, MEMS and Sensors Group delivered $4.07 billion, down from $4.77 billion in 2022 as some consumer-facing end markets softened.
The concentration in automotive and power components is particularly visible in silicon carbide, where STMicroelectronics has targeted significant growth. The company has previously outlined an ambition to reach multi-billion-dollar revenues from silicon carbide devices and modules toward the middle of the decade, supported by multi-year agreements with automotive and industrial customers. In the context of 2023, management indicated that silicon carbide revenue grew strongly from 2022 levels, contributing to the Automotive and Discrete Groups double-digit expansion, though the exact figure for that year-on-year increase is not broken out in detailed numeric form in every communication. For investors, the combination of strong 2023 automotive growth of about 22.7% and the subsequent 2024 revenue guidance decline at group level highlights how resilient segments can be offset by cyclical weakness in more consumer-exposed areas.
Profitability by segment also informs the earnings profile. In 2023, STMicroelectronics reported that the Automotive and Discrete Group delivered an operating margin above the group average, benefiting from product mix and high utilization, whereas the Analog, MEMS and Sensors Group saw margin compression as volumes eased. While exact segment operating-margin percentages are not always outlined to the same precision as the group-level margin, the directional commentary combined with the revenue data suggests that the profit engine increasingly resides in automotive and power semiconductors. If the 14.4% expected decline in 2024 group revenue versus 2023 aligns mainly with weaker personal electronics and some industrial subsegments, the degree to which automotive backlog stays intact will be crucial for earnings resilience.

STM32 microcontrollers as a flagship line
A central product family for STMicroelectronics is its STM32 microcontroller line, which is widely used across industrial, automotive, consumer, and Internet of Things applications. In its 2023 reporting and presentations, the company highlighted that microcontrollers are a key contributor to the Microcontrollers and Digital ICs Group, which posted $5.77 billion of net revenues in 2023 compared with $5.29 billion in 2022, a 9.1% year-on-year increase. The STM32 range, built on Arm cores and offered in numerous variants, enables customers to tailor processing power, connectivity, and power consumption for specific uses such as motor control, smart-home devices, and embedded systems in cars and industrial equipment.
Within this portfolio, STMicroelectronics has been expanding offerings that combine STM32 devices with wireless connectivity, security features, and power-efficient architectures. This strategy aims to capture growing demand for connected, low-power edge devices while maintaining a broad ecosystem of development tools and software libraries. In 2023, the broader microcontroller and digital IC activities benefited from continued demand in industrial and automotive markets, even as some consumer and computing segments normalized after earlier strength. For STMicroelectronics stock, the performance of the STM32 franchise is important because it contributes to both revenue growth and margin profile, helping to balance the more capital-intensive power semiconductor lines.
STMicroelectronics stock and market metrics
STMicroelectronics shares are listed on Euronext Paris and also trade on Borsa Italiana, providing European investors with deep liquidity in the name. As a large-cap semiconductor group, the company is included in major equity benchmarks such as the STOXX Europe 600, making it a reference holding for many regional portfolios and sector funds. In its market disclosures for early 2024, STMicroelectronics indicated a market capitalization in the tens of billions of dollars, reflecting the scale of its operations across multiple semiconductor categories and end markets. For context, the company reported net revenues of $17.29 billion in 2023, and the 2024 guidance midpoint of about $14.8 billion implies that even in a down year the revenue base remains substantial.
From a fundamental perspective, the key question for investors in STMicroelectronics stock is how earnings evolve as the cycle normalizes from the strong conditions of 2022 and 2023. The step down in Q1 2024 net income from $1.04 billion to $513 million year on year illustrates the potential volatility in profits when volumes and pricing soften. Yet the sustained capital expenditure plan of around $3.5 billion to $3.8 billion for 2024, following $4.26 billion in 2023, suggests that management is positioning the company for future growth in automotive, industrial, and power semiconductors rather than retrenching. How quickly demand in personal electronics and some industrial niches recovers will help determine whether margins move closer to the 24.5% operating margin recorded in 2023 or remain closer to the 16.5% seen in Q1 2024.
