Cisco Systems reported strong fiscal fourth-quarter results with revenue surging 18% year-over-year to $17.252 billion, driven significantly by hyperscaler AI infrastructure orders that reached $9.3 billion, a four-and-a-half-fold increase from the prior year. The company posted adjusted earnings per share of $1.22, beating market consensus estimates by over 4%, while networking revenue grew robustly by 28% to nearly $9.8 billion. Beyond its AI infrastructure boom, Cisco demonstrated diversification with security revenue rising 14% to $2.226 billion and annualized recurring revenue increasing 3% to $32.1 billion. However, the rapid expansion in specific segments impacted profitability metrics, as non-GAAP gross margins contracted by 210 basis points to 66.3%, even though non-GAAP operating margins expanded slightly to 35.9%. Looking ahead, Cisco provided guidance for fiscal 2027 revenue between $72.2 billion and $73.4 billion with non-GAAP EPS expected in the range of $5.05 to $5.11. Despite the strong operational performance, analyst sentiment remains mixed; Piper Sandler recently cut its price target to $125 citing concerns that growth may be peaking and valuation multiples could compress. The stock traded around EUR 94.06 on September 30, 2026, remaining well above its 52-week low but trading below the average analyst price target of $129.36. The market capitalization stands at approximately $421.5 billion as investors weigh the impressive top-line growth against margin pressures and potential valuation headwinds.
