Anxiety over slowing automotive semiconductor demand is back, and ON Semiconductor (NASDAQ: ON) is bearing the brunt of it, with shares sliding 5% to $75 in afternoon trading on October 28.
The selloff is sharper for ON than for the company whose guidance triggered it, underscoring how much investors view ON Semiconductor’s silicon carbide EV inverter chips as a direct proxy for auto industry health.
NXP Semiconductors (NASDAQ: NXPI) delivered a technically strong third quarter but paired it with a cautious forward outlook that was enough to send auto-exposed chip names lower across the board.
NXP’s Q3 2026 revenue reached $3.79 billion, a 19% year-over-year increase that edged past analyst consensus of $3.76 billion, while adjusted earnings per share of $4.20 also topped the $4.12 Wall Street expected.
The trouble came with fourth-quarter guidance, where NXP set a revenue midpoint of $3.85 billion against analyst expectations of $3.86 billion, a slim miss that nonetheless implies revenue growth decelerating to 15% from the prior quarter’s 19% pace.
Automotive, which represents more than half of NXP’s total sales, grew just 13% in Q3, lagging the company’s overall growth rate and raising questions about what lies ahead for the segment.
A freshly announced $5 billion buyback expansion from NXP has done little to calm nerves, and TE Connectivity (NYSE: TEL) has separately flagged weaker vehicle production as a headwind to its own fiscal 2027, adding weight to the concern.
ON Semiconductor’s power chip portfolio, which includes silicon carbide devices used in electric-vehicle inverters and industrial power conversion systems, gives the company more auto exposure than most semiconductor peers, explaining why its stock is falling harder than NXP itself.
As recently as August 3, ON Semiconductor’s management described automotive demand as “very stable with a good outlook,” a view that its upcoming quarterly results will either reinforce or walk back.
A revised acquisition of Synaptics (NASDAQ: SYNA), updated earlier this month, adds further complexity to ON Semiconductor’s near-term narrative, leaving investors with multiple moving parts to assess simultaneously.
Not every chipmaker is caught in the same downdraft: Skyworks Solutions (NASDAQ: SWKS) is up 1% to $87, insulated by its focus on radio-frequency chips for smartphones and its close ties to the iPhone supply chain, where auto industry cycles carry little weight.
Qualcomm (NASDAQ: QCOM) and Texas Instruments (NASDAQ: TXN) are each off 1%, trading at $182 and $305 respectively, though both come into the session with substantial year-to-date gains of 8% and 79%.
The broader semiconductor complex is actually holding up, with the iShares Semiconductor ETF rising 1% to $517, a signal that the selling pressure is concentrated specifically in auto-linked names rather than chips broadly.
ON Semiconductor’s own year-to-date gain of 38% gives bulls room to argue the current pullback reflects an overreaction to one competitor’s cautious quarter rather than a fundamental shift in EV demand.
With the Federal Reserve’s policy decision also scheduled for today, traders face a crowded set of variables, and many may choose to wait for ON Semiconductor’s own results before taking a firm directional stance on the auto chip trade.
