ON (ON) Q2 2025 Earnings Call Transcript

ON Semiconductor reported Q2 revenue of $1.47 billion, up 1.6% sequentially and above guidance, with non-GAAP gross margin at 37.6% and EPS of $0.53. Management guided Q3 revenue to $1.465 billion-$1.565 billion and EPS to $0.54-$0.64, while signaling roughly 5% of 2025 revenue will not repeat in 2026 due to portfolio rationalization. The company also returned $300 million via buybacks, maintained $2.8 billion of cash and investments, and highlighted continued growth in AI data center, silicon carbide, and Treo platform demand.

Analysis

ON’s real inflection is not the modest cyclical stabilization; it’s the combination of a lower fixed-cost base and a portfolio intentionally shedding low-quality revenue. That means the next leg of margin expansion is more convex than headline growth suggests: once utilization ticks up from this reset footprint, the gross margin rebound should be faster than prior cycles because a larger share of cost is already stripped out. The market is likely underappreciating how much of 2026’s earnings power will be driven by operating leverage rather than top-line acceleration.

The second-order winner is the company’s higher-differentiation mix: AI power, SiC trench, and Treo each sit in businesses where design wins create longer duration and better pricing resilience than legacy auto/industrial sockets. The AI data center piece is still small, but it is strategically important because it gives ON a foothold in a structurally better growth market where U.S.-based supply chain preference could matter more than pure performance over the next 12-24 months. That could also pressure lower-tier analog and power competitors that lack a credible domestic power architecture story.

The key risk is that investors anchor on the 2025/2026 revenue exit and miss that the company is trading some denominator for quality; near-term reported growth can look sluggish even as economic value per dollar of revenue improves. Another underappreciated risk is that SiC remains margin-dilutive until utilization normalizes, so any slip in EV ramp timing would push out the gross margin recovery into late 2026. Conversely, if utilization improves faster than expected, the earnings revision cycle could be sharp because each point of utilization still carries large basis-point leverage.

Key Decisions for Investors

• Long ON on pullbacks over the next 2-6 weeks; the setup is for a second-half 2025/early-2026 margin revision cycle as utilization recovers. Risk/reward is attractive if the market is still valuing it on near-term revenue exits rather than normalized earnings power.
• Buy ON Jan-2026 or Jan-2027 call spreads instead of common if positioning for a 6-12 month re-rating. The cleanest catalyst is evidence that Q4 utilization and AI data center ramps offset the legacy revenue runoff.
• Pair trade: long ON / short a lower-quality analog peer with more exposed legacy revenue and less visible AI power content. The relative trade favors ON if the market continues rewarding mix improvement and capital returns over raw growth.
• If you want a more tactical expression, sell downside puts into any post-earnings volatility once the stock resets on the 5% 2026 revenue runoff headline. The market should fade that number if management continues to prove the exits are margin-accretive in the medium term.
• Avoid chasing after a strong open; the better entry is on a 3-5% pullback or after confirmation that Q3/Q4 inventory burn is translating into higher utilization, not just higher shipments.
