Cisco Systems shares fell after the networking company projected $7.5 billion in artificial intelligence data center revenue for fiscal 2027, a figure that failed to meet investor expectations despite the company beating broader earnings forecasts.
The guidance amounts to an 87.5 percent increase from Cisco's fiscal 2026 AI infrastructure revenue of approximately $4 billion. Yet the absolute number underwhelmed a market that had priced in steeper growth for one of the major infrastructure suppliers to data center operators building out generative AI capacity. Cisco said the projection reflected what management deemed a prudent assessment of near-term demand.
CEO Chuck Robbins defended the guidance during the company's earnings presentation, stating the forecast was sound and based on broad-based record demand across the business. Cisco reported broader fiscal 2027 revenue guidance between $57.6 billion and $58.8 billion, beating analyst consensus on the top line and showing that AI represented one segment within a larger portfolio performing strongly.
The company's networking equipment sits in the critical path between data center operators and their computing infrastructure. Nvidia, which supplies the GPUs at the core of those systems, has guided for continued triple-digit growth in its data center business through calendar 2026. Cisco's projection was lower, indicating either slower adoption than Nvidia was modeling or a divergence in how different infrastructure vendors saw near-term purchasing velocity.
Investor appetite for AI infrastructure plays has remained voracious since late 2022, but the market has grown increasingly focused on near-term demand signals rather than long-term potential. Cisco's stock response reflected that sensitivity: a decline of approximately 5 to 6 percent on the guidance, despite the company's earnings beat and the AI revenue figure itself representing significant year-over-year expansion.
The $7.5 billion projection carries a potential floor effect on Cisco's total fiscal 2027 guidance, since management committed to a specific number rather than a range. If data center customers accelerate spending beyond current forecasts, Cisco would be constrained by its own public commitment. If spending slows, the company faces downside revision risk.
Cisco's ability to hold this guidance will depend on enterprise and hyperscaler capital expenditure decisions over the next fiscal year. The company will report quarterly results and update its forecast if the underlying demand backdrop shifts materially.
