STMicroelectronics N.V. Q2 2025 Financial Summary

Business Context and Reporting Period

This Form 6-K filing, dated July 24, 2025, reports the second quarter (Q2) 2025 financial results for STMicroelectronics N.V., a global semiconductor leader. The reporting period covers the three months ended June 28, 2025. The company serves customers across Personal Electronics, Industrial, and Automotive sectors. Effective January 1, 2025, the company adjusted its segment reporting structure, reorganizing into two Product Groups (APMS and MDRF) and four reportable segments.

Key Financial Metrics

Non-U.S. GAAP Adjustments: Excluding $190 million in impairment, restructuring, and phase-out costs, Q2 2025 Non-U.S. GAAP Operating Income was $57 million and Net Income was $57 million ($0.06 diluted EPS).

Material Changes vs. Prior Period

• Revenue Decline: Q2 net revenues decreased 14.4% year-over-year (YoY) and 21.1% for the first half. All reportable segments saw revenue declines YoY, with Power and Discrete products falling 22.2% and RF & Optical Communications falling 17.9%.
• Profitability Compression: Gross margin contracted by 660 basis points YoY to 33.5%, driven by product mix shifts, lower manufacturing efficiencies, and higher unused capacity charges.
• Operating Loss: The company reported an operating loss of $133 million compared to an operating income of $375 million in Q2 2024. This shift was primarily due to $190 million in one-time charges related to manufacturing footprint reshaping and cost base resizing.
• Cash Flow: Net cash from operating activities dropped 49.6% YoY to $354 million. Free cash flow turned negative at $(152) million, compared to positive $159 million in the prior year quarter.
• Inventory Build: Inventory increased to $3.27 billion (up from $3.01 billion in Q1), resulting in Days Sales of Inventory (DSI) rising to 166 days from 130 days a year ago.

Guidance, Outlook, and Risks

Q3 2025 Outlook (Mid-point):

• Net Revenues: Expected at $3.17 billion, representing a 14.6% sequential increase and a 2.5% YoY decrease.
• Gross Margin: Expected at 33.5%, including approximately 340 basis points of unused capacity charges.
• Currency Assumption: Based on an exchange rate of $1.14 = €1.00.

Management Commentary: CEO Jean-Marc Chery noted that Q2 revenues exceeded the mid-point of the outlook range, driven by Personal Electronics and Industrial segments, while Automotive was slightly below expectations. The company is executing a program to reshape its manufacturing footprint and resize its global cost base.

Risks and Contingencies:

• Macroeconomic Uncertainty: Risks include inflation, supply chain fluctuations, and uncertain global trade policies, including potential tariff changes.
• Manufacturing Execution: Risks related to ramping new programs, availability of third-party components, and manufacturing performance.
• Customer Demand: Potential divergence from demand projections requiring further transformation measures.
• Geopolitical and Operational: Exposure to geopolitical conflicts, labor actions, and cybersecurity threats.

Key Investor Verification Points

• Restructuring Impact: Verify the timeline and cost savings realization of the $190 million restructuring and manufacturing reshaping program.
• Inventory Levels: Monitor the trend of Days Sales of Inventory (currently 166 days) to assess potential future write-downs or demand recovery.
• Automotive Segment: Assess the recovery trajectory of the Automotive segment, which was below expectations in Q2 and has a book-to-bill ratio below parity.
• Unused Capacity Charges: Track the persistence of unused capacity charges (340 bps in Q3 guidance) as a drag on gross margins.
• Cash Burn: Evaluate the sustainability of negative free cash flow given the high capital expenditure environment ($465 million net capex in Q2).
