STMicroelectronics N.V. Q3 FY2025 earnings call

Management Statement and Operational Highlights:

• Q3 2025 revenues were $3.19 billion, $17 million above outlook midpoint. Gross margin 33.2% slightly below outlook due to product mix. Worked down inventories and generated $130 million free cash flow.
• Automotive: Grew ~10% sequentially, book-to-bill above 1; expects mid-single-digit Q4 growth. Executing car electrification strategy, including silicon and silicon carbide devices for EVs, design wins in active suspension and electronic fuses.
• Industrial: Revenues in line with expectations, 8% sequential growth; inventories in distribution further decreased. Strong design activity in Power and Analog portfolio, robotics demand.
• Personal Electronics: Revenues above expectations, up 40% sequentially; strengthened sensor supplier position with new license agreement.
• AI Data Centers: Multiple wins with silicon and silicon carbide devices; completed power testing on AI data center prototype, photonics ICs as revenue driver.
• LEO Satellites: Strengthened leadership in low broadband market with shipment to second global customer.

Segment Performance:

• Analog Products, MEMS and Sensors: Up 7.0% year-over-year, primarily due to imaging; 26.6% sequential growth. Revenue contribution not explicitly stated by percentage but significant growth.
• Power & Discrete: Decreased 34.3% year-over-year, 4.3% sequentially.
• Embedded Processing: Grew 8.7% year-over-year, 15.3% sequentially.
• RF and Optical Communication: Declined 3.4% year-over-year, 2.4% sequentially. End markets: Industrial up ~13%, Personal Electronic up ~11%, Communication Equipment and Computer Peripheral up ~7%, Automotive still decreasing but improved from prior quarter.

Guidance:

• Q4 2025 revenues expected at $3.28 billion, +2.9% sequentially (+/- 350bps).
• Gross margin expected ~35% (+/- 200bps), including ~290bps unused capacity charges.
• Full-year 2025 revenues ~$11.75 billion, 22.4% growth in second half vs first half.
• Reduced net CapEx plan to slightly below $2 billion for 2025 (previously $2-2.3 billion).

Risks:

• Currency effects impacting gross margin.
• Manufacturing inefficiencies and negative capacity reservation fees affecting gross margin.
• Market recovery uncertainties, especially in certain industrial subsegments like factory automation with low visibility.

Q: On the top line, guidance is +2.9% QoQ, below seasonal. Explain revenue seasonality and drivers. Also, sustainability of gross margin improvement.

A: Revenue seasonality in Q4 affected by automotive (capacity reservation fees from key EV customer) and Industrial (inventory reduction in distribution). Gross margin improvement in Q4 due to improved manufacturing efficiency; sustainability depends on manufacturing efficiency, capacity reservation fees, and pricing negotiations.

Q: How are utilization rates managed, and inventory outlook?

A: Inventory expected to stay stable in days; entering 2026, seasonality and manufacturing footprint reshaping will impact utilization. Reducing capacity in some fabs to mitigate unused capacity.

Q: Linear reduction in capacity reservation fees in 2026?

A: Capacity reservation fees not linearly decreasing; substantially flat quarter-to-quarter, with some decline when contracts expire, remaining stable after initial reduction.

Q: CapEx reduction and impact on 2026?

A: CapEx reduced due to lower demand for silicon carbide and adjustment of test assembly capacity; focuses on mix adaptation rather than volume increase.

Q: Inventory and factory loadings in first half 2026?

A: Inventory may increase slightly in first half then decrease in second half; factory utilization to improve with manufacturing footprint reshaping and revenue growth expectations.
