ON Semiconductor is emerging from its cyclical trough, with AI power growth and margin recovery supporting upside, while automotive normalization, SiC pricing and cash-funded M&A define the risk.
Overview
onsemi designs and manufactures power-management semiconductors, analog/mixed-signal ICs and image sensors, selling to automotive, industrial, energy-infrastructure and hyperscale customers through direct and distributor channels. Its strategic transformation away from commoditized silicon toward SiC, advanced power architectures and sensing has positioned it in secular growth markets, while automotive and industrial cycles remain important. **Q3 2026 confirmed a recovery:** revenue rose 11% YoY to $1.722 billion, non-GAAP gross margin reached 41.2% after five consecutive quarters of expansion, and FCF was $489 million, or 28% of revenue. AI data-center revenue grew 175% YoY to $180 million; management expects FY2026 AI revenue of approximately $620 million and a further doubling in FY2027. Q4 guidance midpoint is $1.765 billion revenue, 42.5% non-GAAP gross margin and $1.01 non-GAAP EPS. Ferric expands the 2030 AI revenue target to more than $3.0 billion, while Synaptics is expected to be immediately EPS-accretive after its planned mid-2027 close. At approximately $72, shares trade at 22.3x FY2026e and 15.8x FY2027e non-GAAP EPS; the five-year base-case target is $129.42, with acquisition execution and automotive normalization the principal near-term catalysts and risks.
