Cisco's CEO, Chuck Robbins, has predicted a significant shift in the market for networking equipment, driven by a phenomenon he calls the 'Mythos Effect'. This term refers to the impact of a powerful bug-finding model, developed by Anthropic, on the tech industry. The model has proven so effective that it's causing vendors and open-source projects to uncover more security flaws and release more patches, leading to a rapid replacement cycle for unsupported devices.
Robbins shared insights from his conversations with customers during Cisco's Q4 earnings call. He noted that buyers are increasingly aware of the potential risks associated with unsupported devices and are taking swift action to replace them. This trend is evident in the growing pipeline of network refreshes, with some customers potentially reallocating their security budgets to fund these upgrades.
The CEO's friend, who runs a major US manufacturer, exemplifies this shift. The friend's team reached out early in the Mythos wave, urging them to prioritize replacing older equipment that had reached the end of its support lifecycle (LDOS). Robbins also mentioned that other Cisco customers have taken similar actions, indicating a widespread concern about the security implications of unsupported devices.
This rapid replacement cycle is one of three factors contributing to a 'supercycle' of network spending, according to Robbins. The other two factors are the need to prepare for quantum computing, either through quantum-safe networks or quantum-resistant decryption, and the rise of AI. Robbins believes that agentic AI will gain traction, leading to increased demand for new networking equipment from hyperscalers and businesses looking to implement AI solutions.
Cisco's financial performance for the quarter was impressive, with revenue of $17.3 billion, a 17% increase year-over-year. Net income rose 51% to $3.9 billion, and the full-year result of $13.27 billion represented a 30% jump. Robbins attributed these strong results to the company's focus on AI, highlighting the successful resolution of 145,000 support cases by AI with zero human intervention during FY26. Cisco's in-house AI Assistant, Circuit, played a significant role, handling over 75 million prompts in Q4 alone.
Despite the positive earnings report, Cisco's share price initially spiked but then settled four percent lower than its closing price, indicating a mixed investor reaction. Robbins' predictions about the Mythos Effect and its impact on the market suggest that Cisco is well-positioned to capitalize on the anticipated surge in network spending, driven by both security concerns and the adoption of AI technologies.
