Cisco Crushes Revenue on AI Surge—But 400% Memory Cost Spike Sends Shares Tumbling to Critical $80 Support

Cisco’s January-end report carried added scrutiny given the extra month of sell-side modeling time, and on the surface the results cleared the bar. The company posted Q2 revenue of $15.3 billion, up 10% year over year and ahead of the $15.1 billion consensus. Adjusted EPS came in at $1.04 versus $1.02 expected, while GAAP EPS of $0.80 rose 31% from a year ago. Yet despite the top- and bottom-line beat, shares are down roughly 8% in pre-market trading, with investors zeroing in on the margin trajectory and what it signals about rising memory costs across the hardware ecosystem.

From a segment perspective, networking once again did the heavy lifting. Core networking revenue climbed 21% year over year to $8.3 billion, well ahead of Street expectations near $7.9 billion, as AI infrastructure demand and a multi-year campus refresh cycle accelerated. Product revenue overall rose 14%, while services slipped 1%. Orders were robust, up 18% year over year, with networking product orders accelerating to more than 20%. AI infrastructure orders from hyperscalers totaled $2.1 billion in the quarter, up from $1.3 billion in Q1 and equal to all of fiscal 2025—clear evidence that Cisco is gaining traction in the AI data center buildout.

The margin picture, however, is where the debate intensifies. GAAP gross margin was 65.0%, roughly flat year over year, while non-GAAP gross margin came in at 67.5%, down from 68.7% in the prior-year quarter. Product gross margins were particularly pressured, reflecting higher component costs and mix shift toward AI-related hardware. Analysts highlighted a roughly 200-basis-point sequential decline in gross margins, with management pointing to a staggering 400% year-over-year increase in memory pricing as a key driver. This is the core reason for the stock’s sharp pre-market pullback: while revenue momentum is strong, hardware profitability is being squeezed by the very AI boom that is fueling demand.

Management was direct in addressing the issue. CEO Chuck Robbins outlined three mitigation strategies: previously announced price increases, revising contractual terms with channel partners and customers, and leveraging Cisco’s scale to negotiate better supply terms. He noted the company will “continue to monitor market trends and make additional adjustments as necessary,” signaling that pricing actions may not be finished. Importantly, Robbins downplayed the risk of significant customer pull-forwards, saying he does not expect a major buy-ahead trend in networking. Still, management acknowledged that gross margin pressure is likely to linger in the near term, particularly as product mix skews toward AI systems and optics.

Operating margins remain relatively healthy despite the gross margin headwind. Non-GAAP operating margin was 34.6%, above the high end of guidance, and GAAP operating margin reached 24.6%, up 21% year over year. However, Q3 guidance implies some compression. Cisco expects non-GAAP gross margin of 65.5% to 66.5% and operating margin of 33.5% to 34.5% for Q3, indicating that margin normalization will not be immediate. This reinforces the market’s concern that elevated memory prices could persist longer than originally anticipated.

On guidance, Cisco did raise its full-year outlook. For fiscal 2026, the company now expects revenue of $61.2 billion to $61.7 billion, up from the prior range of $60.2 billion to $61.0 billion. Non-GAAP EPS is projected at $4.13 to $4.17, slightly ahead of consensus and up from prior expectations. That represents implied revenue growth of roughly 8.5% for the year and signals confidence in sustained enterprise and hyperscaler demand. Q3 revenue guidance of $15.4 billion to $15.6 billion was broadly in line to modestly above expectations, though EPS guidance of $1.02 to $1.04 essentially met consensus—another reason sentiment cooled despite the quarterly beat.

The AI outlook remains one of the most compelling parts of the story. Robbins said Cisco now expects to take AI orders in excess of $5 billion in fiscal 2026 and recognize over $3 billion in AI infrastructure revenue from hyperscalers during the year. That revised target does not include recently announced products such as P200, G300, or newly unveiled optics solutions, suggesting potential upside. In Q2, the mix of AI orders was roughly 60% systems and 40% optics, underscoring the breadth of Cisco’s exposure across silicon, systems, and networking infrastructure.

Beyond AI, the broader networking cycle appears robust. Management described accelerating, double-digit product order growth across all geographies and customer segments, including strength from campus to data center to IoT. Remaining performance obligations rose 5% to $43.4 billion, with product RPO up 8%, indicating sustained visibility. Capital allocation remains shareholder-friendly, with $3 billion returned via dividends and buybacks and a 2% dividend increase to $0.42 per share.

Technically, the stock’s retreat to the $80 level is significant. That area has served as key support in recent months and now becomes a barometer for how seriously investors view the memory cost issue. If shares stabilize and hold this zone, the market may conclude that margin pressure is manageable and largely cyclical. A decisive break below could signal broader concern that AI-driven component inflation will materially erode hardware profitability across the sector.

In sum, Cisco delivered a fundamentally strong quarter marked by accelerating AI orders, robust networking growth, and raised full-year guidance. However, the AI boom is a double-edged sword: while it is driving top-line momentum, it is also inflating input costs and compressing gross margins. The coming quarters will hinge on Cisco’s ability to offset those costs through pricing power and scale. Investors now face a key question at $80: is this a temporary margin air pocket in a powerful networking cycle, or an early warning that hardware players will struggle to convert AI demand into incremental profitability?
