Cisco Says AI Networking Super Cycle Is Just Getting Started, Guides Hyperscaler Revenue to $7.5 Billion as Orders Hit $9.3 Billion in FY26
Q4 FY2026 earnings call, August 12, 2026
Cisco closed out fiscal 2026 with the strongest results in three decades, and management used the call to argue that the company is still in the early innings of what CEO Chuck Robbins repeatedly called a "networking super cycle" tied to agentic AI. Total revenue for the quarter hit a record $17.3 billion, up 18% year-over-year, with product revenue up 24%. Full-year revenue came in at $63.3 billion, up 12%, alongside non-GAAP EPS of $4.33, up 14%. Robbins framed the results plainly: "In FY '26, we delivered the highest revenue, operating margin and earnings per employee in 30 years."
The headline number for investors is the fiscal 2027 guide: revenue of $72.2 billion to $73.4 billion, implying 15% growth at the midpoint, well above Cisco's long-standing 4% to 6% long-term algorithm even after stripping out AI infrastructure revenue. CFO Mark Patterson confirmed that ex-AI, the core business is still growing around 10%, a level he called "obviously significantly faster" than the assumptions underpinning Cisco's last Investor Day.
Hyperscaler AI orders quadrupled, but revenue conversion draws scrutiny
Cisco took $9.3 billion in AI infrastructure orders from hyperscalers in fiscal 2026, roughly 4.5 times the prior year, split about 60% Silicon One-based systems and 40% optics. Q4 alone contributed $4 billion in orders. Management guided fiscal 2027 AI infrastructure revenue to $7.5 billion, up from $4 billion recognized in fiscal 2026 — a doubling, but one that analysts pushed back on as conservative given the order backlog. UBS analyst David Vogt pressed management on why the revenue conversion looked slow relative to the order ramp, asking directly whether shipments were being pushed out beyond 12 months. Patterson's response: these are "nonlinear orders that are massive in scale and are usually placed well ahead of time," and the company is deliberately moving away from giving an annual order target in favor of a firmer revenue target, while still expecting orders to be "meaningfully higher" in fiscal 2027 than fiscal 2026.
Robbins was more explicit about the mechanics of that opportunity, particularly the "scale-across" use case — connecting GPUs across multiple data centers as single-site power and physical constraints bind. He estimated that AI-driven scale-across network traffic is roughly 14 times what traditional data center interconnect traffic used to be, and pointed to three separate hyperscaler design wins for Cisco's P200-powered systems in this category, each already generating orders. A fourth notable win came in managed optical fiber networks, which Robbins described as strategic because it positions Cisco "as an alternative supplier to an incumbent competitor" with the potential to disrupt how optical networks are traditionally delivered.
Silicon One vertical integration and the TSMC relationship
Cisco disclosed plans to roll out its in-house Silicon One architecture "comprehensively" across its high-performance networking systems by fiscal 2029, a move management framed as critical for controlling supply chain exposure and innovation cadence rather than relying on merchant silicon vendors. Patterson was direct about why this matters competitively: "We're not waiting on any sort of allocation and commits and decommits, if you will, from any merchant silicon providers. We're dealing directly with TSMC." He added that Cisco expects to avoid "stacking margins" with third-party silicon providers over time, an underappreciated margin lever a few years out. Both Robbins and Patterson noted a trip to TSMC is already planned, underscoring how central this relationship has become to Cisco's supply security relative to peers who have flagged component tightness.
Enterprise and public sector demand broadens beyond AI hype
Away from hyperscalers, enterprise product orders accelerated to 21% year-over-year with double-digit growth in every product category and geography, while public sector orders grew 30%, helped by accelerating U.S. federal demand. Campus networking orders grew 20%, with Wi-Fi 7 now representing more than half of total wireless orders. Robbins highlighted a large U.S. bank that replaced both a networking competitor and a firewall competitor with 1,000 Cisco data center smart switches, and noted more than half of customers now buy both campus and data center networking products, a cross-sell dynamic management views as a structural advantage over point-product competitors.
A new and somewhat underappreciated demand driver is "Mythos" — Cisco's shorthand for a wave of infrastructure obsolescence and last-day-of-support risk that is pushing enterprises to refresh equipment regardless of budget cycles. Robbins relayed a conversation with a manufacturing CEO whose team called demanding replacement of past-support equipment, saying the CEO's attitude was simply "we don't have a choice and then they figure out how to fund it." Management said 8,000 to 9,000 customers are now running Cisco IQ to audit infrastructure for exposure, and while Mythos-related revenue hasn't shown up materially yet, the pipeline is building — including opportunities to displace competitors' equipment that has also fallen out of support.
Margins: hardware mix headwind, but operating leverage intact
Non-GAAP gross margin fell 210 basis points year-over-year to 66.3%, with product gross margin down 270 basis points to 64.8%, driven by higher hardware mix and elevated memory costs. Management guided fiscal 2027 operating margin to approximately 35%, which Patterson called a company high-water mark despite the gross margin pressure. Robbins argued the mix shift is a feature, not a bug, of the hyperscaler business: "Our expenses to actually capture that growth are minimal in addition to what we spend today... it allows us to take, even in some cases, a lower-margin business from a gross margin perspective that actually turns out to be highly profitable." Price increases tied to memory costs added roughly 5 points to Q4 networking revenue growth, with a similar 4-5 point full-year impact expected in fiscal 2027, weighted toward the first half as Cisco laps last year's increases. Patterson noted these increases have been single-digit in magnitude and narrowly targeted, since memory represents only 15% to 20% of bill-of-materials cost for most Cisco hardware versus roughly two-thirds for server-heavy competitors.
Security recovery is real but Q4 numbers were flattered
Security revenue grew 14% in Q4, including Splunk, but Patterson flagged that the quarter included unusually large on-premise Splunk deals with longer duration that inflated the growth rate. Stripping that out, he guided full-year fiscal 2026 security growth at low single digits, improving to high single digits in fiscal 2027. Robbins noted organic Cisco security products hit "high single digits" exiting the year, in line with prior commentary, with over 6,400 net-new customers since launch and firewall orders up more than 30% for a second consecutive quarter.
Capital returns remained a consistent story, with $12.7 billion returned to shareholders in fiscal 2026 — 99% of free cash flow — and a fifteenth consecutive annual dividend increase. Cisco closed two bolt-on acquisitions in the quarter, Galileo Technologies and Astrix Securities, both aimed at expanding observability and security capabilities rather than representing a shift toward larger, more transformative M&A.
