STMicroelectronics swings to loss in Q2 on lower revenue, charges

STMicroelectronics reported a significant downturn in Q2 2025, posting a net loss of $97 million, a sharp reversal from last year's $353 million net income, as revenue declined 14.4% to $2.77 billion. The semiconductor manufacturer's gross margin narrowed to 33.5% from 40.1%, and it recorded an operating loss of $133 million, driven by broad revenue declines across segments and higher unused capacity charges. Free cash flow turned negative at $152 million, while inventory levels rose. For Q3, the company forecasts revenue of $3.17 billion, a 14.6% sequential increase but a 2.5% year-over-year decline, with gross margin expected to remain flat at approximately 33.5%.

Analysis

STMicroelectronics reported a significant deterioration in its Q2 2025 financial performance, swinging to a net loss of $97 million from a $353 million profit in the prior year. This was driven by a broad-based revenue decline of 14.4% year-over-year to $2.77 billion, with weakness across all product segments, particularly in Power and Discrete products which fell 22.2%. Profitability collapsed as the gross margin contracted by 660 basis points to 33.5%, impacted by unfavorable product mix, manufacturing inefficiencies, and higher unused capacity charges. The company's operational health also weakened, evidenced by a swing to negative free cash flow of $152 million from a positive $159 million a year ago, and a substantial increase in inventory, with days sales of inventory rising from 130 to 166. While the company's Q3 guidance forecasts a sequential revenue increase of 14.6% to $3.17 billion, this still represents a 2.5% year-over-year decline, and the gross margin is expected to remain flat at a depressed 33.5%, signaling that underlying profitability challenges will persist.

Key Decisions for Investors

• Given the sharp swing to a net loss, significant margin compression, and negative free cash flow, investors should recognize the severe operational and profitability headwinds facing the company in the near term.
• The 28% increase in days sales of inventory to 166 is a critical risk indicator, suggesting a potential for future inventory write-downs and continued pressure on margins, which should be monitored closely.
• While Q3 revenue guidance suggests a sequential recovery, the projected 2.5% year-over-year decline and flat gross margin at 33.5% indicate that a fundamental turnaround is not yet evident, warranting a cautious stance.
• The continuation of $173 million in combined dividends and buybacks despite negative free cash flow should be scrutinized, as it may strain the company's net financial position if operating performance does not improve.
