On August 12, 2026, Cisco Systems, Inc. (NASDAQ:CSCO) reported fiscal fourth-quarter earnings and revenue that beat Wall Street estimates and issued guidance well above expectations. Shares still fell as much as 8.4% the following trading day.
Why This Matters
Cisco’s actual numbers were strong by almost any measure, but investors sold the stock anyway, while Arista Networks, Inc. (NYSE:ANET) posted an even bigger beat the same month and saw no comparable selloff.
That raises the real question: is this a sign AI-driven networking demand has already peaked for Cisco specifically, or is the whole networking trade simply getting pickier about which company’s growth story it trusts?
The Bull and Bear Case: Cisco
Revenue grew 18% year over year to $17.25 billion, beating the $16.82 billion analysts expected, and net income jumped 51% to $3.9 billion. CEO Chuck Robbins called it “the fastest-moving technology transition that we’ve ever seen,” saying Cisco Systems, Inc. (NASDAQ:CSCO) hasn’t seen such consistent, elevated demand across its whole portfolio in 30 years. Hyperscalers placed $4 billion in AI infrastructure orders during the quarter, bringing the fiscal year total to $9.3 billion. Cisco expects that figure to reach $7.5 billion in fiscal 2027. The company guided fiscal 2027 revenue to $72.2 billion to $73.4 billion, well above the $68.69 billion analysts modeled.
Piper Sandler analysts wrote that Cisco’s guidance “looks conservative given the current demand environment,” warning that some investors may start to worry growth has already peaked. Cisco Systems, Inc. (NASDAQ:CSCO)’s own gross margin guidance of 65% to 66% for the current quarter is slightly below the 66.3% just reported, a result the company attributes to a sales mix shifting toward lower-margin hardware. Cisco also announced plans in May 2026 to cut fewer than 5% of its workforce, a restructuring expected to cost up to $1 billion, even as demand climbs.
The Bull and Bear Case: Arista
On August 4, 2026, Arista Networks, Inc. (NYSE:ANET) posted its first-ever $3 billion revenue quarter, with second-quarter revenue of $3.036 billion, up 37.7% year over year and 12.1% from the prior quarter. CEO Jayshree Ullal said the results show the company’s “Arista 2.0 platform strategy is compelling,” and that customers now see networking as “the central nervous system” running from client devices through campus and data centers to AI infrastructure. Arista guided third-quarter revenue to about $3.3 billion and non-GAAP earnings per share of $1.06 to $1.08. The firm rolled out a new 1.6-terabit AI fabric platform that cuts interconnect power use by roughly 60% versus older optics. Citi raised its price target on the stock to $215 from $173 on August 6, 2026.
Arista’s growth leans heavily on a concentrated group of hyperscaler and AI customers, the same customer concentration risk weighing on peers like Cisco and CoreWeave if AI infrastructure spending ever slows across the industry.
