Wolfspeed, Inc. introduced its TOLT (TO-Leaded, Top-Side Cooled) package portfolio designed to deliver maximum power density for datacenter rack power supplies. By releasing heat from the top of the package, TOLT significantly improves cooling efficiency, enabling smaller, more reliable power systems that meet the rising demands of AI datacenters.
“AI is pushing datacenter OEMs to be incredibly strategic about the size and total efficiency of their power systems,” said Guy Moxey, vice president of Wolfspeed’s Industrial & Energy business. “Our TOLT product family offers a straightforward path to delivering higher-density, thermally optimized power systems capable of sustaining the demands of AI datacenters, and Wolfspeed’s Gen 4 technology helps these systems run cooler, more efficiently, and more reliably.”
Silicon carbide continues to outpace silicon in high-power applications, supporting gains in performance and system cost across AI datacenters, e-mobility, renewable energy, and battery energy storage. Wolfspeed’s U.S.-based silicon carbide substrate production underpins supply chain resilience and provides a stable domestic source for mission-critical power systems as large AI projects scale.
The initial 650 V TOLT products are available in multiple RDS(on) options, with additional details on Wolfspeed’s third top-side-cooled portfolio to follow in the second half of 2026.

STMicroelectronics N.V. reported Q4 2025 net revenues of $3.33 billion, gross margin of 35.2%, and operating income of $125 million, which includes $141 million related to impairment, restructuring charges and other phase-out costs. The company recorded a GAAP net loss of $30 million, or -$0.03 diluted EPS. On a non-U.S. GAAP basis, operating income was $266 million and net income was $100 million, or $0.11 diluted EPS, including a negative one-time tax impact of $0.18 per share.
For full year 2025, net revenues were $11.80 billion with a gross margin of 33.9%. Operating income totaled $175 million, including $376 million related to impairment, restructuring and other phase-out costs. GAAP net income was $166 million. On a non-U.S. GAAP basis, operating margin was 4.7% and net income was $486 million. Net Capex (non-U.S. GAAP) was $1.79 billion and free cash flow (non-U.S. GAAP) was $265 million.
Management noted that Q4 revenue came in above the mid-point of guidance, driven by Personal Electronics and, to a lesser extent, CECP and Industrial, while Automotive trailed expectations. Gross margin exceeded the mid-point largely on favorable mix, and Q4 marked a return to year-over-year growth.
At the mid-point, Q1 2026 guidance calls for net revenues of $3.04 billion, down 8.7% sequentially—better than average past seasonality—and continuing the Y/Y growth trajectory that began in Q4. Gross margin is expected to be about 33.7%, including ~220 basis points of unused capacity charges. For 2026, the company plans to invest $2.0–$2.2 billion in Net Capex (non-U.S. GAAP).
Strategic priorities include accelerating innovation, executing the program to reshape the manufacturing footprint and resize the global cost base, and strengthening free cash flow generation.
