Cisco Systems reported 18 percent revenue growth in its fourth fiscal quarter ending July 25, 2026, with Chair and CEO Chuck Robbins dismissing concerns the networking vendor has reached its growth peak. Robbins pointed to sustained demand drivers including artificial intelligence infrastructure buildouts, security upgrades prompted by Anthropic's Mythos model, and preparations for quantum computing threats. The company exceeded the upper range of its earlier projections for both the quarter and full fiscal year.
The vendor's results showed product orders jumped 35 percent year over year in the fourth quarter, or 25 percent when excluding hyperscaler customers. Networking product orders climbed 40 percent annually, marking an eighth straight quarter of double-digit expansion. Hyperscaler AI infrastructure orders reached $4 billion in the quarter and $9.3 billion for the full fiscal year, which delivered roughly $4 billion in revenue. The security division expanded 14 percent year over year during the quarter, while Cisco's firewall business posted a second consecutive quarter of 30 percent growth. Within the enterprise segment, Nexus network switch orders designated for AI deployments surged more than 85 percent from the previous quarter. Campus networking product orders rose 20 percent annually, and data center networking orders increased over 35 percent year over year. Revenue from the Americas grew 18 percent, Europe-Middle East-Africa climbed 19 percent, and Asia-Pacific-Japan-China advanced 14 percent. For the full fiscal year, Cisco brought in $63.3 billion in revenue, up 12 percent from the prior year.
According to Robbins, enterprise clients are "reprioritizing spending within existing budgets" and increasingly treating readiness investments around AI, Mythos, and quantum-related vulnerabilities as mandatory rather than optional. The CEO told analysts that customers are shifting dollars from other organizational areas into IT to address these concerns. Robbins noted the spending appears as network refresh activity but is fundamentally driven by cybersecurity considerations. A July survey from KeyBanc found that one-fifth of chief information officers and one-third of value-added resellers reported higher security spending tied to Mythos worries, concentrated on services and labor rather than software purchases. The company's Cloud Control unified operations platform now has roughly 4,500 customers signed up, while the IQ assessment platform serves more than 8,600 customers, giving Cisco and its solution providers opportunities to replace competitor equipment that's past its last day of support.
The results reflect how security threats are reshaping enterprise infrastructure investment cycles. Robbins explained that for the first time, campus networking components—switching, routing, and wireless—are all going through simultaneous refresh cycles driven by overlapping technology transitions. The CEO said network traffic related to AI-based scale-across is roughly 14 times larger than traditional data center interconnect, positioning Cisco's P200 deep-buffer routing and switching chip favorably. The company's Acacia optics business delivered another billion-dollar quarter and secured its first design win in optical networking. CFO Mark Patterson attributed approximately 5 percentage points of quarterly revenue growth to price increases, which affected the first half of the year more heavily than the second, and forecasts another 4 to 5 points of impact in fiscal 2027. For the new fiscal year, Cisco expects $7.5 billion in revenue from hyperscaler AI infrastructure business and total revenue between $72.2 billion and $73.4 billion, with Patterson projecting the core business will grow about 10 percent year over year—significantly faster than previous investor day guidance. Patterson sees security and observability businesses accelerating from low-single-digit growth in fiscal 2026 to high-single-digit growth in fiscal 2027. The transformation extends beyond hardware: Cisco resolved 145,000 support cases in fiscal 2026 with zero human intervention using AI, while its Circuit on-premises AI assistant handled more than 75 million prompts in the latest quarter. These overlapping refresh cycles create a rare window where infrastructure decisions made today will shape competitive positioning for years, as companies balance moving quickly enough to capture AI advantages without rushing implementations that could introduce new vulnerabilities.
