Cisco Posts Record Fourth Quarter as AI Supercycle Accelerates

Fiscal fourth-quarter revenue rose 18 percent and AI infrastructure orders nearly quintupled for the year, yet Cisco shares fell as investors priced in a rally that was already well underway.

Key Takeaways

• Cisco’s fiscal fourth-quarter revenue climbed 18 percent to $17.3 billion, and non-GAAP earnings reached $1.22 a share, both clearing the top end of management’s own guidance range.
• Hyperscaler AI infrastructure orders hit $9.3 billion for fiscal 2026, roughly 4.5 times the prior year, as Cisco’s Silicon One P200 chip secured its third separate hyperscaler design win.
• Shares fell as much as 4 percent after results despite the beat and raised guidance, a reaction owing less to disappointment than to a rally already priced for perfection.

A Fourth Quarter That Outran Its Own Forecast

Cisco Systems closed the books on fiscal 2026 the way it had spent most of the year behaving: ahead of its own forecast. Fourth-quarter revenue reached $17.3 billion for the period ended July 25, 2026, up 18 percent from a year earlier and above both the company’s guidance range of $16.7 billion to $16.9 billion and the roughly $16.83 billion Wall Street had penciled in. Non-GAAP earnings per share came in at $1.22, up 23 percent and ahead of Cisco’s own $1.16 to $1.18 range as well as the Street’s $1.17 estimate. On a GAAP basis, net income rose 51 percent to $3.9 billion, or $0.97 a diluted share, while operating margin expanded to 24.7 percent on a GAAP basis and 35.9 percent on a non-GAAP one, a margin profile unusual for a company still selling physical infrastructure at scale.

What makes the quarter worth dwelling on is not the beat itself but its consistency. Cisco called fiscal 2026 its strongest year in three decades by revenue, operating margin and earnings per employee, a claim the underlying numbers support. Full-year revenue reached $63.3 billion, up 12 percent, GAAP net income rose 30 percent to $13.3 billion, and non-GAAP earnings per share climbed 14 percent to $4.33. Chair and CEO Chuck Robbins credited the results to what he called “the accelerated pace of innovation and the excellent execution by our teams,” a line that reads as boilerplate until set against the fact that Cisco now carries a market capitalization near $487 billion, a figure that now prices in AI infrastructure exposure more than the steadier networking multiple the stock wore for most of the past decade.

Where the Growth Actually Lives

The more interesting number in the release was not revenue already collected but demand still arriving. Total product orders rose 35 percent year over year in the fourth quarter, 25 percent even excluding hyperscalers, with double-digit growth in every geography and every customer segment Cisco reports. Networking orders alone climbed 40 percent, the eighth straight quarter of double-digit growth for that line. Hyperscaler AI infrastructure orders reached $4 billion for the quarter and $9.3 billion for the full year, against $2 billion in fiscal 2025, a nearly fivefold increase that Cisco expects to convert into roughly $7.5 billion of hyperscaler revenue in fiscal 2027, up from about $4 billion delivered this year.

The order book also reveals where Cisco has chosen to compete. Three new hyperscaler design wins landed in the quarter: a Silicon One P200 system built for scale-across architectures that stitch together geographically separated data centers, a G200 system for scale-out clusters within a single facility, and an optical line win, bringing Cisco’s total P200 commitments to three distinct hyperscalers. Product revenue overall rose 24 percent, led by Networking’s 28 percent climb to roughly $9.8 billion; Security grew 14 percent, Collaboration 12 percent, Observability 6 percent. Growth was similarly broad by geography, with the Americas up 18 percent, EMEA up 19 percent and Asia-Pacific, Japan and China up 14 percent, a spread that undercuts any suggestion the AI order book is a story about one or two customers.

The Discipline Behind the Numbers

None of that growth came at the expense of discipline, which is the part of the Cisco story easiest to overlook amid the AI headlines. GAAP product gross margin rose to 62.6 percent from 61.5 percent a year earlier, a gain achieved even as component costs, memory in particular, sat near the top of analysts’ watch lists heading into the print. Operating cash flow reached $5.4 billion for the quarter, up 27 percent, and cash and investments stood at $15.9 billion at quarter’s end. Remaining performance obligations, the closest proxy Cisco offers for contracted future revenue, rose 7 percent to $46.7 billion, with product RPO up 9 percent, a sign that the order surge is converting into durable backlog rather than a burst of one-time bookings.

Capital allocation followed the same disciplined pattern. Cisco returned $3.2 billion to shareholders in the quarter through dividends and buybacks, lifting the fiscal 2026 total to $12.7 billion, or 99 percent of free cash flow, and the board declared a quarterly dividend of $0.42 a share. That discipline extended to headcount: a restructuring plan announced May 13 alongside third-quarter results, meant to redirect spending toward silicon, optics, security and AI, cost Cisco roughly $450 million of an expected $1 billion in pretax charges this quarter and touched fewer than 4,000 roles, under 5 percent of its global workforce. Two smaller acquisitions closed in the period, observability specialist Galileo Technologies and non-human-identity security firm Astrix Securities, both narrowly targeted additions rather than the kind of transformative deal that tends to unsettle a balance sheet.

A Rally the Stock Declined to Join

Wall Street’s response to all of this was to sell. Cisco shares fell roughly 2 percent in initial after-hours trading and were down as much as 4 percent by the next session, despite a quarter and a fiscal 2027 outlook that cleared consensus on essentially every line. Some of that reaction was mechanical: options markets had priced an implied swing of roughly 8 percent around the release, and the shares had already climbed nearly 60 percent year to date, with UBS and KeyBanc lifting price targets on AI demand checks in the days before the print. What followed looked less like disappointment than profit-taking after a rally that had outrun the news, a sharp contrast with May, when the same AI-order narrative sent the stock up roughly 13 percent in a single session.

Valuation explains part of the restraint. Cisco now trades at a forward earnings multiple in the high twenties, a premium to its own history that leaves less room for a beat alone to move the needle, even with the average Wall Street price target of $136.23 still implying upside from a Moderate Buy consensus of 11 Buy and four Hold ratings. There is a competitive undercurrent here too, one the AI narrative tends to obscure. Nvidia’s Spectrum-X platform became the leading vendor by data center Ethernet switch revenue in the first quarter of 2026, with roughly 21.5 percent share, ahead of Arista Networks near 19 percent, with Cisco trailing both. The order growth is genuine, but it is being won inside a switching market where hyperscalers increasingly favor GPU-vendor and merchant silicon over the incumbent’s own platforms.

The Guidance, and the Question Beneath It

Guidance suggests Cisco expects the acceleration to continue rather than level off. For the first quarter of fiscal 2027, the company guided to revenue of $18.0 billion to $18.2 billion and non-GAAP earnings of $1.32 to $1.34 a share. For the full year, Cisco pointed to revenue of $72.2 billion to $73.4 billion and non-GAAP EPS of $5.05 to $5.11, implying growth of roughly 14 to 16 percent, a pace well above the company’s decade-long norm and an unusually confident promise for a business of Cisco’s size.

The risks sit where they usually do. Management flagged tariff exposure explicitly in its forward-looking disclosures, and two structural questions remain genuinely open: how quickly $46.7 billion in remaining performance obligations converts into recognized revenue, and how much runway is left in a campus-networking refresh cycle that Cisco says has touched only about 7 percent of its installed base. For investors who have already bid the stock up in anticipation of an AI-driven supercycle, the question this quarter answers is no longer whether Cisco’s numbers are strong. They are, unambiguously. The harder question, and the one the market’s muted reaction was quietly asking, is whether a networking incumbent built for an earlier era can keep converting that order growth into market share against rivals built for this one.
