The supercycle is a hyperscaler pull-forward and the margin tells on it. Networking decays back toward low single digits once the current build lands, Services stays flat, Security stays at 2%, and the multiple reverts toward Cisco's own pre-AI history at 3x sales. FY2027 comes in a shade under the guided floor. What this case does NOT assume is an AI revenue decline: the guided $7.5bn is still delivered. It assumes Cisco is worth what it was worth the last time it grew like this.

The smallest disclosed line: $275M in the basis quarter, $1,095M and +4% for FY2026, +6% in Q4. ThousandEyes, AppDynamics and now Galileo Technologies. Subscale against Datadog and Dynatrace, and it matters to this model as an option rather than as a driver. No ARR and no customer count are published.

Assumptions & reasoning

  • At 1.6% of revenue this line cannot move the valuation: even doubling its terminal growth changes fair value by cents. It is carried because Cisco reports it, not because it drives the answer.
  • Margin 15% rising to 22% is assumed: a subscale software line still absorbing acquisitions, reaching software scale economics without a step-change in size. Nothing in the filings discloses this line's profitability.
  • Every vertical margin here is assumed. Cisco discloses gross margin by geography (Americas 64.5%, EMEA 70.1%, APJC 67.3% in the basis quarter) and product-versus-services gross margin, and never operating profit, capex or headcount by product category.
  • The two July quarters are derived, not printed: FY2024 Q4 and FY2025 Q4 are the fiscal-year column of the 10-K less the nine-month column of that year's Q3 10-Q, and both reconcile to the quarterly totals Cisco printed later, so they carry estimated: true.
  • Capex intensity is the consolidated rate applied to every line: FY2026 property and equipment $1,410M on $63,325M of revenue is 2.2%, and Cisco publishes no capex by product category to split it with.
