Cisco (CSCO) Q2 2026 earnings review

AI Acceleration and Networking Refresh Power Strong Beat

Cisco delivered a decisive beat-and-raise quarter, breaking out of single-digit growth with a 10% YoY revenue increase to a record $15.3B. The narrative has shifted aggressively to AI: hyperscaler AI infrastructure orders hit $2.1B in Q2 alone—exceeding the entire FY25 total. Core Networking also surged (+21% YoY) on a campus refresh cycle. However, the victory lap is dampened by a 4% contraction in Security revenues and a concerning divergence where Net Income rose 31% while Operating Cash Flow fell 19%.

🐂 Bull Case

Hyperscale AI Explosion

The AI narrative is real and accelerating. AI infrastructure orders from hyperscalers totaled $2.1B in Q2 alone, up from $1.3B in Q1. This exponential ramp validates Cisco's Silicon One and optical strategy.

Networking Core Revival

Networking revenue jumped 21% YoY, driven by a 'multi-year' campus refresh cycle. Product orders grew 18% overall, with networking orders accelerating to >20% growth, signaling broad enterprise demand beyond just AI.

🐻 Bear Case

Security Segment Weakness

Despite the Splunk integration, Security revenue fell 4% YoY to $2.0B. Management cites a transition to cloud/subscriptions, but in a high-threat environment, shrinking revenue in a key growth pillar is a red flag.

Cash Flow Divergence

Quality of earnings is in question. While Net Income surged 31% to $3.2B, Operating Cash Flow dropped 19% to $1.8B. This disconnect often signals working capital strain or aggressive revenue recognition timing.

⚖️ Verdict: 🟢

Bullish. The sheer velocity of AI orders ($2.1B) and the resurgence of the core Networking business (+21%) outweigh concerns about Security transition and cash flow timing. Guidance raise confirms the momentum is durable.

Key Themes

DRIVER🟢🟢

AI Infrastructure Hyper-Growth

Accelerating. AI demand has shifted from 'promising' to 'massive.' Orders from hyperscalers reached $2.1B in Q2, reflecting a significant acceleration from $1.3B in Q1. Management noted this is driven by AI training and inferencing clusters using Silicon One and Acacia optics.

DRIVER🟢

Networking Refresh Cycle

Accelerating. Networking revenue grew 21% YoY ($8.3B), a massive swing from the declines seen in FY25. Management cites a 'multi-year, multi-billion-dollar campus networking refresh cycle' as enterprises upgrade for Wi-Fi 7 and AI-readiness. This confirms the recovery of the core hardware business.

CONCERN

Security Transition Drag

Reversing. Security revenue declined 4% YoY to $2.0B, making it the worst-performing product segment. While RPO is up, the shift of Splunk and security deals to cloud subscriptions is creating a near-term revenue headwind that obscures underlying demand.

CONCERNNEW🟢

Operating Cash Flow Disconnect

Diverging. Operating Cash Flow (OCF) fell 19% YoY to $1.8B, moving in the opposite direction of Net Income (up 31%). Receivables decreased significantly YoY (positive), but the drop in OCF alongside rising inventory (up to $3.9B from $3.1B in Q4 FY25) suggests capital is tied up in building inventory for the AI ramp.

THEME🔴

Gross Margin Compression

Decelerating. Non-GAAP Gross Margin compressed to 67.5% from 68.7% a year ago. This likely reflects the mix shift toward hyperscale AI infrastructure hardware, which carries lower margins than software/enterprise networking. As AI becomes a larger chunk of revenue, margin headwinds may persist.

Other KPIs

Networking Revenue$8.29 billion

Accelerating. Up 21% YoY. This is the engine room of Cisco, and it is firing on all cylinders again after a inventory correction year in FY25.

Inventories$3.92 billion

Increasing. Up from $3.16B at the end of FY25. This 24% increase likely reflects the build-up of expensive components (GPUs/memory/optical) required to fulfill the surging $2.1B in AI orders.

Remaining Performance Obligations (RPO)$43.4 billion

Stable. Up 5% YoY. Product RPO grew faster at 8%, with Long-Term Product RPO up 11%, indicating customers are signing longer commitments, likely related to the Splunk/Security transition.

Guidance

Q3 FY26 Revenue$15.4 - $15.6 billion

Accelerating. The midpoint ($15.5B) implies continued sequential growth and robust YoY performance compared to Q3 FY25 ($14.1B). This suggests no slowdown in the order book conversion.

FY 2026 Revenue$61.2 - $61.7 billion

Accelerating. Raised from prior expectations. The midpoint ($61.45B) implies roughly 8.5% YoY growth, a significant improvement over the flat/negative trends of FY24/25. Includes estimated tariff impacts.

FY 2026 Non-GAAP EPS$4.13 - $4.17

Stable/Accelerating. Midpoint ($4.15) suggests ~9% growth over FY25 ($3.81). EPS growth is keeping pace with revenue growth despite margin pressure from the AI hardware mix.

Key Questions

Cash Flow vs Income Divergence

Net income grew 31% while Operating Cash Flow dropped 19%. Is this solely due to inventory build for AI orders, or are there billing/collection timing issues with the hyperscaler contracts?

Security Growth Inflection

With Security revenue down 4% despite the massive Splunk acquisition being fully integrated, when does the segment return to positive growth? Is the transition drag accelerating?

Hyperscale Margin Impact

With AI orders exploding to $2.1B, Non-GAAP gross margins compressed 120bps YoY. What is the long-term margin profile of this hyperscale revenue stream compared to the corporate average?
