Broadcom Forecasts $21.7B in Quarterly AI Chip Sales After a 221% Surge

Broadcom has set a new near-term marker for the AI infrastructure buildout: $21.7 billion in AI semiconductor revenue for its fiscal fourth quarter. The forecast follows a completed quarter in which that business reached $16.7 billion, up 221% from a year earlier, yet the company’s shares were broadly flat as investors weighed an outlook slightly below the analyst revenue consensus cited by The Motley Fool.

The hardware Broadcom is selling into AI buildouts

Broadcom identified two products behind the expansion: custom AI accelerators and networking. Accelerators are chips designed for AI computing, while networking connects computing equipment in a data center. Chief Executive Hock Tan said demand for both remained very strong. The company recorded $29.6 billion in total third-quarter revenue, with semiconductor solutions contributing $20.8 billion, or 70% of that total.

That makes the AI figure more than a general signal of technology spending. It is a reported sales measure for a defined semiconductor category that grew 54% from the preceding quarter, according to Broadcom. The company’s broader revenue rose 86% year over year in the fiscal quarter ended August 2, a period that also included 29% growth in infrastructure software revenue.

A forecast is not booked revenue

Broadcom expects fourth-quarter companywide revenue of about $34.8 billion, which would be 93% higher than the prior-year period. It also expects non-GAAP operating income of roughly 66% of projected revenue, flat from a year earlier. Those figures are company guidance, not completed results; Broadcom said actual performance could vary materially from its estimates.

The projected AI revenue growth rate is faster than the third-quarter rate, but the comparison has a limit. The $16.7 billion figure is realized revenue, while the $21.7 billion number is management’s expectation for a quarter ending November 1. The company’s earnings release also notes risks around customer demand, supply-chain capacity, trade conditions and dependence on significant customers.

Profit and cash rose with sales

The expansion also produced sharply higher earnings and cash generation. GAAP diluted earnings per share were $2.68, up 215% year over year; non-GAAP diluted earnings were $3.32, up 96%. Broadcom generated $14.2 billion in operating cash flow and $13.7 billion in free cash flow after $0.5 billion in capital expenditures.

But stronger results did not resolve the expectations problem. Broadcom’s fourth-quarter revenue guide was about $34.8 billion, versus a $35 billion analyst consensus cited by The Motley Fool. That narrow gap, alongside a premium valuation cited by the publication, helped explain why the shares did not rally despite rapid AI growth and higher profit.

For AI-industry readers, the result is a concrete demand signal for a supplier whose AI business spans computing chips and the connections between them. It does not establish how long that pace can last, nor does it show whether Broadcom will meet its fourth-quarter goal. The next earnings report will turn the current forecast into a delivered result—or expose the distance between AI infrastructure demand and the expectations embedded in the market.
