Lattice Semiconductor Q3 Revenue Surges 118% YoY; ON Semi and AEIS Also Beat

The Quick Take

• Lattice Semiconductor Q3 2026 revenue rose 118% year-on-year to record levels
• Advanced Energy Industries (AEIS) posted record Q3 results with revenue up over 50% YoY
• ON Semiconductor (ON) beat Q3 guidance on revenue, gross margin, and EPS
• Semiconductor earnings season confirms robust AI data centre and industrial demand

The third-quarter 2026 earnings season delivered strong results across multiple semiconductor segments, with Lattice Semiconductor posting a 118% year-on-year revenue increase to a new quarterly record, Advanced Energy Industries reporting over 50% revenue growth versus the prior year, and ON Semiconductor beating all three guided metrics including gross margin and earnings per share. Together, the results confirm that the semiconductor upcycle is broadening beyond AI chip leaders to include FPGA players, power management specialists, and compound semiconductor manufacturers that serve data centre, industrial automation, and renewable energy markets.

Lattice's 118% revenue surge is particularly notable because the company serves the edge-AI and industrial FPGA market, suggesting that AI inferencing demand is diffusing from hyperscale data centres into factory automation and enterprise computing. AEIS's record performance in power delivery components for semiconductor manufacturing equipment confirms that wafer-fab capital expenditure remains robust. ON Semiconductor's beat across all guided metrics, combined with its raised Q4 outlook, signals that automotive and industrial end-markets are recovering from the 2025 inventory correction cycle. Peers including Microchip Technology, Renesas, and Infineon are likely to see positive pre-results sentiment.

Investors should model the Q4 guidance ranges from all three companies as the next critical data point, since the sustainability of the upcycle determines whether current semiconductor valuations are supported by earnings momentum. The key macro variable is global data-centre capital expenditure, which is the demand engine for all three companies' primary end-markets. Any slowdown in hyperscaler spending guidance from Microsoft, Amazon, or Google would flow through to tighter semiconductor order books within two to three quarters. Watch the book-to-bill ratio disclosures from SEMI, the industry association, as a leading indicator of order momentum.
