ON Semiconductor: Why I Am Raising My Price Target After Q2 2026

ON Semiconductor reiterated as a Strong Buy with a raised $139 price target after Q2 2026 results exceeded expectations: revenue rose 9% y/y to $1.604B, non-GAAP EPS was $0.74, and operating margin expanded to 20.8%. The AI data center power segment remains the fastest-growing business, with management now expecting AI revenue to more than double in 2026, reinforcing the investment thesis.

Analysis

ON’s AI power exposure is starting to matter more than its legacy cyclical end markets, which is why the stock can keep rerating even if macro semis stay choppy. The key second-order effect is mix: power content per AI rack is expanding fast enough that investors should pay up for suppliers with credible efficiency/thermal advantages, not just raw unit growth. That favors ON, MPS, and select wide-bandgap names, while slower-growth analog peers with heavier auto/industrial exposure risk looking like value traps on a relative-growth basis.

The next 1-3 months are about estimate revisions and whether hyperscaler capex remains broad-based enough to keep AI power orders from becoming a one-quarter story. The main falsifier is not a bad print; it is evidence that AI power is a small-base acceleration without follow-through, or that margin expansion stalls as ON scales capacity. If gross margin gives back even modestly while revenue guides up, the market will quickly discount the thesis as volume-led rather than structurally higher content per watt.

Contrarian view: consensus may be underestimating how much of the upside is already visible in the headline, and overestimating the durability of a double-digit growth rate in a capital-intensive subsegment. The more interesting trade is relative: ON can outperform even if semis as a group pause, because its earnings mix is shifting toward a scarcer growth pocket. But if AI capex broadens into a general semiconductor upswing, ON’s relative edge narrows and the pair trade becomes less attractive.

Key Decisions for Investors

• Long ON on pullbacks over the next 1-3 months; thesis is continued multiple expansion from AI power mix, with downside thesis broken if the next guide implies AI power deceleration or sub-20% operating margins.
• Pair trade: long ON / short TXN for a 3-6 month horizon to isolate AI-power exposure versus more cyclical analog exposure; risk/reward is attractive if AI capex stays resilient, but flatten if broad industrial demand re-accelerates.
• Use a trailing alert on ON if the stock moves to a much higher implied growth multiple before the next earnings print; if the market starts pricing perfection, take profits because the incremental upside then depends on a second clean beat, not the current thesis.
• Watch MPS and STM as confirmation basket names; if they echo the same power-demand commentary, it validates a sector-wide re-rating, but if they do not, ON may be winning share rather than signaling a broader cycle.
