Broadcom just posted one of the most brutal single-day market cap losses in recent memory. The semiconductor giant shed more than $250 billion in market value after its forward revenue guidance failed to meet the sky-high expectations Wall Street had baked into the stock.

The numbers behind the bloodbath

Broadcom guided for third-quarter fiscal 2026 revenue of approximately $29.4 billion, representing an 84% increase from the same period a year ago. The company also projected non-GAAP operating margins of around 67%.

For context, Q2 fiscal 2026 revenue came in at $22.2 billion, up 48% year-over-year. Adjusted EBITDA hit $15.2 billion for the quarter.
