STMicroelectronics' (STM) financial report today is a double explosion of AI infrastructure and Musk's concept!!! Q1 revenue was $3.1 billion, a year-on-year increase of 23%, exceeding market expectations of $3.06 billion. The Book to Bill ratio in all end markets and regions is significantly higher than 1, and distribution channel inventory has returned to normal. This marks the official end of the destocking cycle and strong customer replenishment momentum. It is expected that Q2 revenue will reach $3.45 billion, a year-on-year increase of 24.9%, far exceeding the average seasonal performance. ST has clarified its role in AI infrastructure in this financial report - 'Connect, Cool, and Power'. AI related revenue is expected to exceed $500 million by 2026, with a target of breaking through $1 billion by 2027. About 60% of the revenue comes from microcontrollers (MCUs), radio frequency, and optical communications; 40% comes from analog and power semiconductors. In addition, ST has achieved high mass production of the 12 inch wafer PIC100 silicon photonics platform at the Crolles factory. ST is one of the few manufacturers in the world with the ability to mass produce 12 inch silicon photonics. This can meet the high bandwidth and low latency interconnection requirements between AI clusters (such as NVIDIA GPU arrays) through optoelectronic integration. Thirdly, ST announced a multi-year, multi billion dollar strategic agreement with Amazon Web Services (AWS). This collaboration covers comprehensive semiconductor support from high-performance computing infrastructure to 800V power conversion solutions (reducing grid high voltage directly to GPU core voltage). Fourthly, ST disclosed that its LEO satellite business is in a period of rapid growth, with an expected cumulative revenue of over 3 billion US dollars from 2026 to 2028. Although not named directly, ST has revealed that it is developing power amplifier controllers for Direct to Cell satellites for its "main customers". Considering the current market situation, this is almost confirmed as Starlink's core order. In addition, the supply of the second largest customer is also increasing in volume (I am curious who this may be), and its technological advantage lies in the BiCMOS process and panel level packaging, which greatly reduces the production threshold and cost of aerospace grade chips. Fifth, Manufacturing Transformation and Gross Profit Margin: Short term Pain, Long term Improvement The gross profit margin for Q1 is 33.8%, and it is expected to rebound to 34.8% in Q2 (35.2% under Non GAAP). Transition costs: Currently, the gross profit margin is constrained by temporary inefficiencies and idle production costs caused by manufacturing transitions (such as 200mm to 300mm, SiC from 6 inches to 8 inches). With the increase in factory utilization and the popularity of 8-inch silicon carbide (SiC), ST aims to maintain a long-term gross profit margin of over 40%. Conclusion: Cycle Recovery and Incremental Market STMicroelectronics is currently at the intersection of "cyclical recovery" and "structural growth". In addition to the steady recovery of traditional automotive and general MCU businesses, AI infrastructure (silicon photonics, power management) and low orbit satellites have become the backbone driving its valuation. The next key point: The company will hold a special meeting on LEO satellite business on May 4, 2026, at which more specific financial models regarding the $3 billion business will be announced.
