AI Summary

5.0
Neutral

ON's investability now hinges on proving that AI data-center power can become a scalable, high-margin growth engine before the leveraged, dilutive Synaptics acquisition and uneven automotive/industrial recovery undermine the improving cash-flow and margin trend; investors should await tangible AI design-win traction and a sustained move above $73–$74 before assigning a strategic premium.
