STMicroelectronics Shares Tumble on Core Profit Miss and Weak Q3 Forecast
Summary
The chipmaker's stock fell sharply after its second-quarter core EBITDA fell short of expectations and its third-quarter revenue guidance disappointed investors, overshadowing beats on headline revenue and EPS.
Shares of STMicroelectronics (STM) plunged in pre-market trading after the semiconductor company's second-quarter earnings report revealed a significant miss on core profitability and a weaker-than-expected forecast for the third quarter, stoking investor concerns about its near-term growth trajectory.
Disappointing Q2 Results and Outlook
STMicroelectronics reported its Q2 2026 financial results before the market opened, posting figures that sent mixed signals. While top-line results surpassed analyst expectations, underlying profit and the company's forward guidance fell short.
Key figures from the report include:
- Q2 Net Revenues: $3.49 billion, ahead of Wall Street estimates.
- Q2 Non-GAAP Diluted EPS: $0.31, also beating consensus.
- Q2 Core EBITDA: $679 million, a substantial miss compared to the analyst consensus of approximately $797.7 million.
The company attributed the core profit shortfall to writedowns, restructuring costs, and accounting effects related to its acquisition of the NXP sensor division.
AdLooking ahead, management's guidance for the third quarter of 2026 also disappointed. The company forecast Q3 revenue with a midpoint of $3.70 billion, which is below the consensus estimate of roughly $3.9 billion. The gross margin is expected to recover to only around 37%.
Market Reaction and Context
The market reacted swiftly to the news, with STMicroelectronics shares falling 14.6% in U.S. pre-open trading. The sell-off began during European hours, where the stock dropped below the key €50 level in both Milan and Paris, dragging down the broader Stoxx Europe 600 index.
Analysts noted that the cautious Q3 revenue forecast may reflect a slower production ramp for the upcoming iPhone 18. While CEO Jean-Marc Chery highlighted that Q2 revenue was driven by strength in Automotive products, investors focused on the weaker margin profile and near-term volume concerns.
Despite the sharp single-day decline, it is important to note the stock's performance in a wider context. Prior to this drop, shares of STMicroelectronics were up more than 110% year-to-date, and the current pullback follows an exceptionally strong run.
