Q3 FY2026 Earnings: Record Revenue and Beat

On May 13, 2026, Cisco Systems (NASDAQ: CSCO) reported its strongest quarterly performance on record. The company posted Q3 FY2026 revenue of $15.8 billion, a 12% year-over-year increase, surpassing the high end of its own guidance range of $15.4–$15.6 billion and exceeding Street consensus of approximately $15.2 billion. Non-GAAP EPS came in at $1.06, also ahead of expectations. Networking revenue alone grew 25%, while total product orders rose 35% year over year. Data center switching orders climbed over 40%, and campus networking orders increased more than 25% as customers continued refreshing infrastructure for AI workloads. CEO Chuck Robbins declared that "Cisco is well-positioned as the critical infrastructure for the AI era."

AI Infrastructure Orders: From $5B to $9B Forecast

The defining headline of the Q3 print was Cisco's decision to nearly double its full-year FY2026 AI infrastructure order forecast — from over $5 billion to $9 billion, representing greater than 4x the level of the prior fiscal year. In Q3 alone, hyperscalers ordered $2.1 billion from Cisco's Silicon One portfolio, advanced networking solutions, and optical products for AI data centers. This matched the record $2.1 billion booked in Q2 FY2026, which was itself up from $1.3 billion in Q1. The $9 billion full-year AI infrastructure forecast notably excludes the newest hardware — the Silicon One G300 and P200 — meaning the product cycle for FY2027 is not yet reflected in current guidance. Cisco's AI orders run approximately 60% Silicon One systems and 40% optics for data centers.

Silicon One G300: The Hardware Engine Behind the Growth

Central to Cisco's AI networking surge is the Silicon One G300, a 102.4 Tbps switching ASIC unveiled at Cisco Live EMEA in February 2026. The G300 powers the new Cisco N9000 and Cisco 8000 systems, designed for hyperscalers, neoclouds, sovereign clouds, service providers, and enterprises. The G300 features Intelligent Collective Networking — combining a fully shared packet buffer, path-based load balancing, and proactive network telemetry — delivering 33% increased network utilization and a 28% reduction in AI job completion time versus non-optimized alternatives. The 100% liquid-cooled systems achieve a nearly 70% energy efficiency improvement, delivering the same bandwidth in a single system that previously required six prior-generation systems. Cisco's Silicon One platform has now shipped one million chips, with the G300 scheduled for commercial deployments in the second half of 2026. The new N9000 and 8000 systems built on G300 are positioned as the first products designed to compete directly for the largest AI back-end fabrics in 2026 and 2027.

Astrix Security Acquisition: Securing the Agentic Workforce

Alongside its earnings release, Cisco confirmed its intent to acquire Astrix Security, a Tel Aviv-based startup founded in 2021 by Alon Jackson and Idan Gour, both veterans of Israel's Unit 8200. Astrix specializes in Non-Human Identity (NHI) security — governing API keys, service accounts, OAuth tokens, and AI agents that increasingly access enterprise systems autonomously. Industry reports pegged the deal's value at approximately $400 million, though Cisco did not officially confirm financial terms. Cisco plans to integrate Astrix's capabilities into Cisco Identity Intelligence and extend them across Cisco Secure Access and Duo Identity and Access Management. AI agents and other non-human identities now outnumber human users in enterprise environments by roughly 100 to 1, creating significant blind spots for security teams. Cisco frames the acquisition as extending Zero Trust principles to the emerging "agentic workforce," where AI agents represent an entirely new attack surface growing faster than most organizations realize.

Restructuring: 4,000 Job Cuts to Fund AI Pivot

On the same day as its earnings report, Cisco announced a restructuring plan to reduce headcount by fewer than 4,000 roles. The company estimates pre-tax charges of up to $1 billion — primarily severance and one-time termination benefits — with approximately $450 million expected in Q4 FY2026 and the remainder in FY2027. The restructuring is explicitly aimed at freeing resources to invest in key growth areas: silicon, optics, security, and artificial intelligence. This marks Cisco's second major restructuring in two years, underscoring the speed at which the company is realigning its workforce toward AI-era priorities.

Raised Guidance and Market Reaction

Following the Q3 beat, Cisco raised guidance across every time horizon. Q4 FY2026 revenue was guided to $16.7–$16.9 billion, exceeding the Street consensus of approximately $15.82 billion by roughly $1 billion. Full-year FY2026 revenue guidance was lifted to $62.8–$63.0 billion versus the prior consensus of $61.6 billion, with EPS climbing to $4.27–$4.29. The stock surged approximately 14% in after-hours trading following the report, adding to an already strong 30% year-to-date gain. At a record close of $98.72 pre-earnings, shares crossed $102 post-print, with analysts at Evercore ISI maintaining a Buy rating and a $110 price target, citing expectations that AI-centric revenues could accelerate from approximately $3 billion in FY2026 to $12–$15 billion within three to four years.

Industry Implications for IT Networking Professionals

Cisco's Q3 results and accompanying announcements signal a structural shift in global networking infrastructure. Enterprise networking teams should be aware of several key trends: First, the transition from GPU-centric to network-centric AI performance is accelerating — as AI models scale into tens of thousands of accelerators, network congestion, not compute, is becoming a primary performance constraint. Second, the proliferation of AI agents in enterprise environments is creating urgent demand for Non-Human Identity governance, a skill area largely absent from traditional network security curricula. Third, the Ethernet switch market is seeing explosive growth — IDC reported 62% year-over-year market growth in Q3 2025, with 800GbE switches surging 91.6% sequentially. For IT professionals pursuing networking certifications (such as CCNA, CCNP, CCIE, or equivalent), this moment reinforces the importance of understanding AI-ready infrastructure design, Zero Trust architectures, high-density switching platforms, and liquid-cooling data center topologies — all now active deployment priorities at hyperscale and enterprise levels globally.
