Broadcom Inc. Q3 2026 Earnings Recap

Shares fell 3.4% as investors reacted coldly to cautious commentary on growth sustainability and sales momentum beyond the AI semiconductor surge, despite record revenue and margins.

Key Takeaways

• Q3 revenue hit $29.6 billion, up 86% year-over-year, driven primarily by AI semiconductor sales.
• AI semiconductor revenue grew 221% year-over-year and 54% sequentially, accounting for a large portion of overall growth.
• Operating margin reached a record 68%, reflecting significant operating leverage.
• Management highlighted robust deployments of custom accelerators (XPUs) to major AI customers but gave measured outlook beyond current ramp, signaling potential deceleration risks.
• Guidance projects Q4 AI revenue of $21.7 billion, up 236% year-over-year, yet the market’s sell-off suggests skepticism about the sustainability of this growth or potential margin pressure going forward.
