ON's AI Data Center Business Surges 30% Sequentially, Bolstering Growth Narrative

What happened

ON's AI data center revenues surged 30% sequentially in Q1, driven by hyperscaler demand and next-gen power systems, fueling expectations of a multi-year growth cycle. Despite this strength, the master report maintains a WAIT rating, noting that the company's core automotive and industrial markets remain in a cyclical trough, with gross margins still depressed near 38%. The AI data center momentum adds upside optionality but does not yet offset the structural risks around SiC execution, LTSA amendments, and the aggressive $6B buyback plan. With the stock trading at ~$60, the risk/reward remains unattractive until there is clearer evidence of sustained auto recovery and gross margin improvement into the low-40s. While the AI tailwind is a positive development, the overall investment thesis hinges on a broader demand recovery, and the current valuation offers limited margin of safety.

Implication

Longer-term, if ON can sustain AI data center momentum alongside a resumption of auto/industrial growth, it could support the bull case toward $80. However, execution risks, LTSA fragility, and the need for gross margin expansion justify patience; wait for a more attractive entry near $50 or confirmation of margin recovery.

Thesis delta

The reported 30% sequential growth in AI data center revenues is a modest positive but does not alter the core thesis. The master report already included AI/data center as a growth driver; this data point adds evidence but is not sufficient to shift from WAIT to BUY. The key catalysts remain auto recovery and gross margin improvement, which are still unconfirmed.
