Cisco Stock Tumbles 8.8% as AI Hardware Squeezes Margins
Cisco (CSCO) fell about 8.8% after reporting fiscal Q4 results with revenue up 18% to $17.3B and adjusted EPS up 23% to $1.22, plus AI-infrastructure orders of $4B in the quarter and $9.3B for the year. Cisco forecast AI revenue of about $7.5B in FY2027, but adjusted gross margin dropped 210 bps to 66.3% and FY1 outlook implies 65%-66%, pressuring shares.
How this was made

The 30-second read
Why it matters
The disclosed gross margin decline and first-quarter outlook range provide a concrete reason for the stock’s sharp drop, framing AI demand as less profitable than expected.
Market read
Traders may reassess valuation support for AI infrastructure beneficiaries if margin conversion lags demand growth.
What to watch
The article emphasizes gross margin and a first-quarter outlook, but does not quantify cost actions, mix shifts, or longer-term profitability targets that could offset the near-term squeeze.
Background
Cisco reported fiscal fourth-quarter revenue and earnings growth, with AI-infrastructure orders rising sharply, but investors focused on margin deterioration.
Ticker impact
Cisco shares fell about 8.8% despite record quarterly results, as adjusted gross margin dropped 210 bps to 66.3% and guidance implies continued margin pressure.
Near-term downside bias until investors see margin stabilization or a clearer path from AI orders to higher profitability.
The article ties the same-day selloff to a specific profitability deterioration (gross margin down 210 bps) and a first-quarter outlook range that suggests the squeeze persists, which is actionable for positioning around earnings/guidance expectations.
Market effects
Highlights a broader AI networking theme where demand growth may not translate into near-term margin expansion for infrastructure vendors.
No specific regional spillover described.
AI infrastructure capex demand remains intact, but profitability conversion is the key global investor concern.
Counterpoint
The margin compression could be temporary as Cisco ramps AI-related networking volumes, with operating leverage potentially improving later in the cycle.
