The Bear case, 20 quarters out

Each segment is projected from its own operating driver, rolled up into consolidated cash flow, and discounted back to a fair value per share. The assumptions below are editable — change them and every number on this page moves with them.

Quarter labels are Cisco FISCAL quarters, so 2026 Q4 is the thirteen weeks ended 25 July 2026, reported 12 August 2026. The five verticals are exactly the groups of similar products and services Cisco discloses — Networking, Security, Collaboration, Observability, Services — and they sum to reported consolidated revenue in all twelve quarters, with a maximum residual of $1M, which is the rounding Cisco itself discloses. Ten of the twelve quarters are read from the filed disaggregation-of-revenue note; FY2024 Q4 and FY2025 Q4 are fiscal year less nine months and are flagged estimated. AI infrastructure is NOT a vertical: it is disclosed annually only (about $4bn of FY2026 revenue, $7.5bn guided for FY2027, $9.3bn of FY2026 orders) and sits inside Networking. Every vertical margin is assumed, because Cisco discloses gross margin by geography and never by product category; the 0.5% corporate overhead is the plug that reconciles the revenue-weighted assumed margins ($22,351M) to the disclosed FY2026 non-GAAP operating income of $22,040M. Segment 'EBITDA' here therefore tracks Cisco's non-GAAP operating margin, which excludes share-based compensation of $3,830M. Tax 18.5% is the company's own FY2027 non-GAAP assumption. netCash is cash $7,218M plus investments $8,700M less short-term debt $10,161M and long-term debt $19,372M, so Cisco is $13.6bn net DEBT. Shares are the 3,941,434,665 on the Q3 FY2026 10-Q cover; the FY2026 10-K was not filed as of 2026-08-27. Price is the 26 August 2026 close of $112.36. The engine carries no seasonality, and Cisco's fiscal Q1 is seasonally its weakest quarter, so the base case is calibrated to the FULL-YEAR guide: FY2027 lands at $73.3bn inside the guided $72.2-73.4bn, with the first projected quarter at $17.9bn just under the guided $18.0-18.2bn. Reading the quarter alone would have broken the year.

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.

Switching, routing, wireless and servers: $9,791M in the basis quarter, 56.8% of revenue and all of the growth. Q4 +28% year over year and FY2026 +22% after two down years, on networking product orders +40% and an eighth consecutive quarter of double-digit order growth. The hyperscaler AI infrastructure business lands here — about $4bn of FY2026 revenue against $9.3bn of FY2026 orders, guided to $7.5bn in FY2027. Cisco publishes no units, ports or capacity for this line, so sequential growth on the reported category is the only honest driver.

Assumptions & reasoning

  • AI infrastructure is modelled inside this line and never as its own vertical. Cisco discloses AI revenue and AI orders once a year, so a quarterly AI series would be an invented sub-line that double-counts against Networking.
  • The order book runs above recognised revenue: $9.3bn of FY2026 AI orders against about $4bn of AI revenue, and product RPO of $23,436M, +9%. Orders are visibility, not revenue, so they inform the growth path rather than set it.
  • Opening 5.5% sequential puts FY2027 networking near $42.7bn, +23% on FY2026's $34,668M, which is the growth the consolidated $72.2-73.4bn guide needs given a flat Services line and a 2% Security year.
  • Margin 37% is assumed: non-GAAP product gross margin less consolidated operating expense, with the terminal at 34% because the hardware mix that took Q4 non-GAAP gross margin from 68.4% to 66.3% is treated as permanent.
  • 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.

The Splunk line. $2,226M in the basis quarter, +14% year over year, but only +2% for FY2026 at $8,232M once the acquisition anniversary washed through. Cisco publishes no security ARR, no seats and no Splunk-versus-legacy split, so this is a reported-category growth line and not a subscription model.

Assumptions & reasoning

  • FY2026 grew 2%; strip the Q4 +14% and the line is flat. The model takes the middle of those two facts rather than extrapolating the quarter, because Cisco publishes nothing that would show whether Splunk is compounding.
  • Margin 25% is assumed and is the lowest of the four product lines: this line carries the heaviest purchased-intangible amortisation and the Splunk cost base. The terminal 28% assumes that integration cost is absorbed, not that it disappears.
  • 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.

Assumptions & reasoning

  • Quarterly revenue has sat between $987M and $1,167M for twelve straight quarters, so a flat sequential path is the honest projection; the Q4 +12% is read as a device quarter rather than as a new trend.
  • Margin 30% is assumed, fading to 28%, on a mature software-and-device mix whose price is capped by competitors that bundle the same functionality into a suite. Cisco discloses no profitability for this category.
  • 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.

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.

Technical support, software maintenance and advanced services: $3,793M in the basis quarter and $15,030M for FY2026, against $15,046M in FY2025 — exactly flat while the company grew 12%. Services RPO is $23,298M, +6%, so the book is growing faster than recognised revenue. There is no ARR and no renewal rate, so this is a growth line anchored to a backlog observation rather than a subscription driver.

Assumptions & reasoning

  • The single largest judgement in this model. Services was flat to the dollar in FY2026 while its RPO grew 6%, and the release does not say whether that is recognition timing or price erosion in support renewals. The base takes a partial catch-up at 4% a year; the bear case takes none.
  • Half of the recurring base sits here and it contributed nothing to a +12% year, which is why hardware mix, not services, is what moves the margin line in every scenario below.
  • Margin 40% flat is assumed from non-GAAP services gross margin of 71.2% less consolidated operating expense. It is the most stable line Cisco has and no visible margin lever attaches to it.
  • 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.

4.5x terminal-year revenue. Cisco trades at 7.17x FY2026 sales today — EV $456.5bn on a $442.9bn market cap and $13.6bn of net debt, 24.4x EV/EBITDA and 33.4x trailing earnings — after a 52-week run from $66.13 to $130.37. That is roughly double the multiple it carried through its flat years, and the exit is deliberately a de-rate toward what a mature networking incumbent earns once it is no longer priced on an order book: 4.5x sales is about 13x the terminal EBITDA this model projects, against 16x if the AI mix holds and 24.4x today. Arista is the pure-play comparable at 23.0x sales and 52.3x EBITDA; Cisco is already carrying an AI multiple on a business where AI was about 6% of FY2026 revenue. Move the exit multiple before anything else — it is worth more than any growth assumption here. The discount rate is 8.5%, an investment-grade mega-cap cost of capital on a levered balance sheet.

Read the other way round: at $112.15 the market is paying 8.5x terminal-year revenue, holding every other assumption on this page fixed. That is the number to argue about.

Every row is projected. A year-over-year change is shown only where the quarter it compares against exists — an em dash means there is no comparable quarter, not a flat year.
