[CSCO] Cisco Thesis 2026: Splunk Integration + AI Infrastructure Test Software Transition
Cisco FY2025 (Jul 2025) revenue ~$54B with adj. operating margin ~31% as Splunk acquisition (closed March 2024 for $28B) full-year contribution lifted Security and Observability segments. Subscription mix expanded to 56% (from 44% FY2021) — software/subscription transformation accelerating. AI infrastructure orders reached ~$1B FY2025 with management targeting $3B+ by FY2027. FY2026 thesis: Splunk integration delivering ~$1B cost synergies by FY2027 (currently ~$300-400M realized) plus growing revenue synergies; AI infrastructure share capture (Cisco Silicon One + AI-optimized switches) addressing hyperscaler + enterprise AI deployment networking; networking demand stabilization; key risks: Arista Networks AI infrastructure share gain at Cisco's expense, Splunk customer churn post-acquisition, enterprise networking demand cycle.
