Cisco (CSCO) Q1 2026 earnings review
AI Boom Fuels Strong Beat and Raise, Overshadowing Security Revenue Slip
Cisco started fiscal 2026 on a strong footing, beating revenue and EPS estimates driven by an explosion in AI-related demand. The company reported a massive $1.3 billion in AI infrastructure orders and raised its full-year guidance, forecasting roughly $3 billion in AI revenue this year. This AI momentum, coupled with the start of a multi-year campus networking refresh, propelled the core Networking segment to 15% growth. However, the positive narrative was tempered by an unexpected 2% revenue decline in the Security segment. Management attributes this to a timing issue from a customer shift to cloud-based Splunk subscriptions, but the contraction is a notable blemish on an otherwise stellar quarter.
🐂 Bull Case
The AI growth story is accelerating significantly. Cisco booked $1.3 billion in AI infrastructure orders in Q1 alone and expects to recognize ~$3 billion in AI-related revenue in FY26, with orders projected to more than double from FY25's $2B+ total.
Management highlighted the start of a multi-year, multi-billion-dollar campus networking refresh cycle. With next-generation switches and Wi-Fi 7 products ramping faster than prior launches, this provides a durable tailwind for the core business.
🐻 Bear Case
The Security segment's revenue fell 2% YoY, a sharp reversal from prior quarters. While explained as a timing issue due to a Splunk cloud shift, it raises questions about the immediate top-line contribution from the landmark acquisition.
Excluding the booming hyperscaler business, growth appears more muted. Enterprise product orders grew only 4% YoY, lagging far behind the 45% growth from Service Provider & Cloud customers, suggesting a heavy reliance on the AI buildout.
⚖️ Verdict: 🟢
Bullish. The sheer scale and acceleration of the AI opportunity, validated by $1.3 billion in quarterly orders and a raised full-year guide, are powerful enough to outweigh the concerns around the Security segment's revenue timing. The campus refresh cycle adds another layer of durable growth. While the Security miss warrants monitoring, the AI narrative is compelling and driving the business forward.
Key Themes
AI Infrastructure Demand Reaches Fever Pitch
Cisco's AI business is the primary growth engine. The company booked $1.3 billion in AI infrastructure orders from hyperscalers in Q1, a significant acceleration. Management now expects to recognize roughly $3 billion in AI revenue in FY26 and forecasts FY26 AI orders to be at least double the $2B+ achieved in FY25. This demand spans Silicon One systems, optics, and routers, with the company winning deals across all major hyperscalers.
Security Revenue Declines Despite Positive Demand Signals
The Security segment's revenue contracted 2% YoY, a significant red flag that contradicts the positive narrative. Management explained this was not a demand issue but a revenue recognition timing problem caused by a higher mix of Splunk cloud subscriptions, which are recognized over time, versus on-premise deals recognized upfront. While Splunk's recurring revenue metrics (ARR and RPO) grew double-digits, the negative headline revenue number is a key point of concern for investors.
Multi-Year Campus Networking Refresh Cycle Kicks Off
Management signaled the beginning of a major, multi-year campus networking refresh opportunity. This is driven by aging equipment (Cat 4k/6k nearing end-of-support) and the need for enterprises to modernize their infrastructure for AI. The company noted that its next-generation solutions, including smart switches, secure routers, and Wi-Fi 7 products, are all ramping faster than previous product launches, indicating strong early demand.
Operating Cash Flow Diverges from Net Income Growth
Operating cash flow was $3.2 billion, a decrease of 12% year-over-year. This contrasts with GAAP Net Income, which grew 5% to $2.9 billion. Management attributed the decline to working capital investments needed to meet the rapidly growing customer demand for AI infrastructure. While this is a plausible explanation, the negative cash flow trend warrants monitoring to ensure efficient working capital management.
Sovereign and Enterprise AI Pipeline Builds
Beyond hyperscalers, Cisco sees a growing pipeline for AI solutions from sovereign nations, neo-cloud providers, and enterprises. The company highlighted a pipeline exceeding $2 billion for high-performance networking products for these customers for the remainder of FY26. Strategic partnerships, like the one with G42 in the UAE, are progressing, representing a significant future growth layer not yet reflected in current results.
Other KPIs
RPO, a measure of future contracted revenue, grew 7% YoY to $42.9 billion. Product RPO was particularly strong, growing 10% YoY to $21.9 billion. This provides solid visibility into future revenue streams and reflects healthy underlying demand.
Cisco returned $3.6 billion to shareholders in Q1, comprising $1.6 billion in dividends and $2.0 billion in share repurchases. The company has $12.2 billion remaining under its current stock repurchase authorization, signaling a continued commitment to capital returns.
Guidance
Accelerating. Cisco raised its full-year guidance significantly. The new revenue range midpoint of $60.6B is up from the prior midpoint of $59.5B. This implies ~7% YoY growth. The new EPS range midpoint of $4.11 is up from $4.03 previously, implying ~8% YoY growth and continued operating leverage.
Slightly Accelerating. The midpoint of $15.1 billion implies 8.7% YoY growth. This represents a slight acceleration from the 8.0% growth reported in Q1 FY26, indicating continued strong momentum into the second quarter.
Decelerating. The midpoint of $1.02 implies 8.5% YoY growth. This is a modest deceleration from the 10% YoY growth seen in Q1, likely reflecting mix shifts and continued investments.
