onsemi agrees to sell two chip plants, targeting $35M in annual savings - StreetInsider

US semiconductor company onsemi has agreed to sell two chip manufacturing facilities in Arizona, aiming for $35 million in annual cost savings. This strategic move reflects the current challenges faci... Read original →

onsemi’s divestiture of two Arizona fabs isn’t just a $35M cost cut—it signals the accelerating retreat of traditional IDM models in mature nodes. Technically, this pushes onsemi deeper into Fab-lite territory, prioritizing high-margin SiC and intelligent power design, but risks weakening control over legacy 8-inch specialty processes critical for automotive MCUs. Regulatory-wise, the U.S. CHIPS Act’s focus on advanced nodes renders older fabs financially unsustainable, making asset sales a hedge against policy misalignment. Rivals like Infineon and STMicroelectronics may follow suit, offloading non-core capacity while deepening partnerships with foundries in Taiwan, China and Southeast Asia. Over the next 12–24 months, expect a second wave of semiconductor asset fire sales—especially in power and analog segments—as capital concentrates among top players and mid-tier IDMs face existential pressure.
