onsemi Raises Utilization on AI Data Center Demand, But Core Auto/Industrial Recovery Unclear

What happened

onsemi announced it is increasing factory utilization to meet stronger AI data center demand, with AI data center revenue expected to more than double, while maintaining its longer-term focus on automotive and industrial end markets. While this highlights a bright spot in an otherwise weak demand environment, AI data center sales remain a small fraction of onsemi's revenue, which is still dominated by cyclical automotive and industrial segments that have been contracting. The news may signal a shift in product mix toward higher-growth markets, but it does not yet address the core issues of auto/industrial slowdown, low overall utilization, and margin compression that have driven the stock's underperformance. Management's decision to boost utilization suggests improving orders, but it remains to be seen whether this is a sustainable ramp or a temporary response to short-term demand. Overall, the announcement is marginally positive but does not alter the thesis that ON needs a broader recovery in its core end markets to justify its valuation.

Implication

For investors, this news provides evidence that onsemi's AI data center strategy is gaining traction, which could eventually offset weakness in traditional end markets. However, the company's heavy reliance on automotive and industrial cycles means that a sustained recovery in those segments is still required for meaningful earnings growth. The current valuation at ~77x trailing P/E and ~10x EV/EBITDA leaves little room for error, and the stock is trading near the upper end of our base-case range, making a buy less attractive. We would prefer to see gross margin move into the low-40s and auto revenue grow sequentially before becoming more constructive. Until then, we maintain a WAIT stance, with attractive entry points near $50 and trim levels above $75.

Thesis delta

The news does not materially change our investment thesis. While AI data center momentum is encouraging, it is too small to offset the ongoing weakness in automotive and industrial, which remain the primary drivers of onsemi's financial performance. We maintain our WAIT rating, but we will monitor whether AI-related revenue growth can scale meaningfully and contribute to overall utilization and margin recovery.
