Cisco Systems

Phase A — Understand the business

Lens 1 · Company Overview

Cisco designs, sells and services IP networking hardware and the software/subscriptions that run on it. Four product categories (FY2025 product revenue $41,608M of $56,654M total; services $15,046M):

All figures.

Business-model mechanics. Revenue mix is shifting hard toward software and ratable recognition: FY2025 software revenue $22.3B (+21%), total subscription revenue +15%, driven largely by a full year of Splunk vs ~4 months in FY2024. Hardware/perpetual software recognize upfront on transfer of control; term licenses split (license upfront, maintenance ratable); SaaS ratable. RPO $43.5B at FYE2025 (≈$21.7B short-term) — the contracted backlog that underwrites the recurring story.

Customers & channel. Three end-markets: Enterprise, Public Sector, and Service Provider & Cloud (the webscale/hyperscaler bucket where the AI revenue sits). Sold ~80%+ indirectly through channel partners (systems integrators, resellers, two-tier distribution); ~25,600 sales & marketing staff. No single customer ≥10% of revenue in FY2025/24/23 — but see Lens 13: the AI orders are concentrated in a handful of hyperscalers even if total revenue isn't. Payment terms typically net-30; Cisco also extends vendor financing.

Contract structure: mostly purchase orders under master agreements, not take-or-pay. Increasingly recurring at the software layer, still transactional at the hardware layer. Verdict on the model: a transactional hardware business wearing a growing software/subscription overcoat, now bolted to a lumpy, project-driven AI-capex order stream.

Lens 2 · Supply Chain

Upstream → Cisco → end customer, named where the filings/web disclose it:

• Silicon / inputs (upstream): Cisco is fabless. Its Silicon One switching/routing ASICs and the Nvidia-adjacent AI stack are manufactured by external foundries (TSMC is the industry default for leading-edge networking silicon ). Cisco also still buys merchant silicon from Broadcom (Tomahawk/Jericho) for parts of its portfolio, making Broadcom simultaneously a supplier and a competitor. Memory and optics components are a current chokepoint — management explicitly flagged "memory constraints and costs" as pressuring Q3 FY2026 product gross margin and drove inventories up to $4.7B from $3.2B.
• Contract manufacturers (the assembly chokepoint): Cisco outsources box assembly to EMS providers (industry: Foxconn/Hon Hai, Flex, Jabil, Celestica ). The filings carry a recurring liability for noncancelable purchase commitments with contract manufacturers and suppliers — provisions of $493M FY2025 (down from $819M FY2024). A supplier legal dispute over long-term supply purchase obligations was settled Aug 26 2025, producing a GAAP charge to product COGS that dented Q4 FY2025 gross margin by part of a 1.2pp move (exact $ not separately disclosed).
• Cisco (midstream): integrates silicon + optics + software (IOS XR, NX-OS, Splunk) into switches (Nexus N9000, Cisco 8000), routers, and now AI-fabric systems.
• Distribution → end customer: two-tier (distributors → SIs/resellers → end users) for enterprise; direct for the largest hyperscalers on AI infrastructure. End buyers for the AI line: four hyperscalers with triple-digit-% growth in FY2026, plus named mega-projects — Cisco is a disclosed participant in OpenAI/Oracle/SoftBank/Nvidia/G42 "Stargate" (UAE) and has cited five P200 design wins with hyperscalers/cloud builders.

Chokepoints / single-source dependencies: (1) leading-edge foundry capacity (TSMC) — shared with every AI peer; (2) HBM/memory and advanced optics supply — the live FY2026 margin chokepoint; (3) EMS concentration. Names present → lens passes.

Lens 3 · Competitive Advantages (moats)

Where the moat is real:

• Installed base + switching costs (enterprise). Decades of Catalyst/Nexus switches, IOS expertise, certifications (CCNA/CCIE), and SmartNet support contracts create high enterprise stickiness — the source of the $43.5B RPO and a services line that throws off recurring margin.
• Full-stack scale. Cisco is one of very few vendors that owns silicon (Silicon One) + optics + systems + network OS + security (Splunk) + observability. CEO Robbins' explicit pitch: AI-infrastructure players "without silicon will struggle to be relevant". The 1-millionth Silicon One chip shipped in Q2 FY2026.
• Distribution. A global channel no startup can replicate cheaply.

Where the moat is thin (critical):

• In the hyperscale AI data center — the actual growth engine — Cisco is the challenger, not the incumbent. Arista leads the merchant/"black-box" AI-Ethernet segment with vastly better unit economics (ANET ROIC ~30.8%, ROE ~31.5% ). Broadcom arms the white-box ecosystem (Tomahawk 5 / SONiC). Google, Meta and Amazon increasingly design their own networking and lean white-box. Cisco's switching moat does not travel cleanly into a customer base that has the engineering talent to disintermediate it.
• Bargaining power is inverted in AI. In enterprise, Cisco has pricing power over a fragmented buyer base. In AI infrastructure, the buyers are four-to-six hyperscalers with their own silicon programs and merchant-silicon alternatives — they hold the power, which is exactly why AI revenue carries lower gross margin (Lens 5).

Net: a wide moat in a slow-growth pond (enterprise networking), a narrow-and-contested foothold in the fast river (AI fabric). The bull thesis requires the foothold to widen faster than the pond drains.

Lens 4 · Segments

Cisco reports operating segments geographically (Americas / EMEA / APJC); product categories are a supplemental disaggregation. It does not allocate R&D/S&M/G&A, SBC, intangible amortization or litigation to segments, so "segment gross margin" is the deepest profitability cut available.

By geography — FY2025 revenue / segment gross margin:

US revenue specifically was $30.4B FY2025 (vs $28.7B/$29.9B). Note FY2023 (pre-Splunk, post-COVID-backlog peak) was higher total revenue than FY2024 — the dip-then-recovery is the inventory-correction cycle management keeps referencing.

By product (trend & cause):

• Networking −3% FY2025 ($28.3B): servers and campus switching declined as shipments normalized from the inflated H1-FY2024 backlog-burn. Then it inflected: Q3 FY2026 Networking product +25%, driven by AI Infrastructure + Campus. This single line is the entire story — the legacy core is now the AI vehicle.
• Security +59% FY2025 ($8.1B): almost entirely the Splunk consolidation (Threat Intelligence/Detection/Response), plus SASE. But organic momentum stalled: Security was flat in Q3 FY2026 — a yellow flag on the $28B Splunk bet.
• Observability +26% FY2025 ($1.1B): Splunk observability + ThousandEyes. Decelerated to +3% product in Q3 FY2026.
• Collaboration ~flat / −1%: Webex secular decline, partly offset by devices/CPaaS.

Latest geographic print (Q3 FY2026, qtr ended Apr 25 2026): total revenue $15,841M (+12%); Americas $9,569M (+14%, product +20% led by US +22% on AI), EMEA $4,054M (+9%), APJC $2,218M (+9%, with China product +42%). Services $3,724M (−1%) — the recurring base is not what's growing; hardware is.

Phase B — Measure performance

Lens 5 · Earnings Result (latest print — Q3 FY2026, reported May 13 2026)

The print:

• Revenue $15.841B, +12% YoY (vs $14.149B). Product +17%, services −1%. Record quarterly revenue.
• GAAP diluted EPS $0.85 (+37%); non-GAAP EPS $1.06. GAAP net income ~$3.4B.
• Beat: revenue and EPS both topped consensus; shares hit a record after the print.
• What drove it: Networking product +25%, specifically AI Infrastructure (hyperscaler Silicon One/optics) + Campus refresh. AI-infrastructure orders $1.9B in the quarter, YTD $5.3B — already past the original $5B FY2026 target with Q4 to go.

Margins — the tension. Total gross margin −2.0pp YoY; product gross margin −2.5pp, "primarily driven by negative impacts from product mix and higher memory costs". This is the central financial fact of the thesis: the AI revenue Cisco is winning is structurally lower-margin than its legacy networking, and a memory-cost cycle is compounding it. Operating margin still rose +2.4pp on revenue leverage + lower intangible amortization + lower opex ratio (−3.8pp) — so the P&L absorbed the GM hit this quarter. Whether it keeps doing so as AI scales is the open question.

Balance sheet / cash flow flags:

• Inventories $4.708B vs $3.164B at FYE2025 (+49%) — a deliberate memory/component build ahead of AI shipments; raises obsolescence risk if AI orders cool.
• Total debt up to ~$31.3B ($11.93B short-term + $19.37B long-term) from $28.1B — short-term debt more than doubled.
• 9-mo operating cash flow $8.791B vs $9.959B (−12%) — working capital (inventory build, tax payments) consumed cash even as earnings rose. A real, if explainable, divergence between earnings and cash.
• RPO flat at $43.5B, deferred revenue flat at $28.6B — the backlog isn't growing; the growth is being recognized, not accumulated.

FY2025 full-year context: revenue $56.654B (+5%), operating income $11.760B (20.8% margin), net income $10.180B (−1% YoY — a tax artifact: effective tax 8.3% FY25 vs 15.6% FY24, i.e. pre-tax income actually rose), diluted EPS $2.55 (flat). Total gross margin 64.9% ($36,790M).

Market reaction signal: the stock has nearly doubled in a year (52-wk range ~$65.75 → $130.37) and was at $117.22 on Jun 29 2026, ~10% off its $130 ATH (Jun 4 2026). The market is paying for the AI order trajectory, not the 5% legacy growth.

Lens 6 · Earnings Calls (sentiment trend)

No transcripts on the research-layer shelf (transcripts/ empty); reconstructed from web coverage of the FY2025–FY2026 calls, labeled accordingly.

Tone arc — decisively up and to the right:

• FY2024 / early FY2025: defensive — post-COVID inventory digestion, Splunk integration "don't screw it up" (Robbins), guidance resets. Theme: recovery and absorption.
• Q1 FY2026 (Nov 2025): inflection — AI orders $1.3B in the quarter, guidance raised, "AI-led networking demand". Theme: AI demand is real and accelerating.
• Q2 FY2026 (Feb 2026): $2.1B AI orders in 90 days (≈ all of FY2025 in one quarter); 1-millionth Silicon One chip; Robbins escalates the silicon-as-moat framing.
• Q3 FY2026 (May 13 2026): peak confidence — record revenue, AI order guide raised $5B→$9B, FY26 AI revenue $3B→$4B, CFO Patterson floats "at least $6B of [AI] revenue in FY27". Robbins: Cisco is "critical infrastructure for the AI era"; players "without silicon will struggle to be relevant."

Recurring phrases now: "AI infrastructure," "Silicon One," "scale-across/scale-up," "agentic era," "broad-based demand," "four hyperscalers." What they stopped saying: "inventory normalization," "demand digestion." What's conspicuously under-emphasized: organic Security/Splunk growth (flat in Q3), services (declining), and a clean answer on whether AI gross margins improve with scale.

Sentiment read: management has fully pivoted the narrative from "stable dividend incumbent" to "AI-infrastructure beneficiary." The orders back it up. The risk is classic late-cycle confidence — the most bullish guide coincides with the highest multiple and the largest inventory build.

Lens 7 · Comps

Peer set: AI-networking and adjacent infrastructure/security names. Multiples are with source/date; where a figure isn't cleanly sourced it is marked n/a — not fabricated. Cisco's own market data is; Cisco fundamentals are.

Read. Cisco is the cheap, low-growth, dividend-paying name in a peer set of expensive high-growth pure-plays. ANET trades ~44x forward for ~30% growth and ~30% ROIC; Cisco ~24x forward for ~10–12% EPS growth and far lower ROIC. The bull case is not that Cisco deserves Arista's multiple — it's that a 0→$9B AI order ramp justifies a re-rate from "ex-growth utility" (~14–16x, where it sat for years) toward the low-20s, which has already largely happened (the stock doubled). A direct ROE comp: ANET ~31% vs Cisco — derived FY2025 ROE ≈ $10.18B net income / ~$48.9B equity ≈ ~21% ÷ total equity $125,546M assets − $76,685M liabilities = $48,861M, Q3 FY26 balance sheet ]. Decent, but flattered by the 8.3% FY2025 tax rate and balance-sheet leverage.

Lens 8 · Stock-Price Catalysts (>5% moves, ~5yr pattern)

What actually moves CSCO:

• The AI-orders number is now THE catalyst. Each quarter the AI-infrastructure order figure (and the FY guide) has driven the print reaction: +7% on the Q1 FY2026 guide raise; record highs on Q3 FY2026's $5B→$9B raise. Cisco +32% in a month (to late May 2026) while Arista fell ~10% — an explicit AI-networking-trade rotation into the incumbent.
• Guidance resets (down) historically hammered it — Cisco's pre-AI era was defined by post-earnings drops on soft forward revenue guides and the FY2024 inventory-correction warnings.
• Splunk deal (Sep 2023 announcement): shares fell — investors disliked the $28B price and the leverage.
• Dividend/buyback moves the needle little (yield ~1.45%; raises ~2.5%/yr — too small to be a catalyst).
• Macro/rates matter as for any mega-cap, but idiosyncratically the name now trades on hyperscaler AI-capex sentiment — it has effectively re-coded itself from "IT-spend cyclical" to "AI-infrastructure derivative."

Pattern verdict: the market reacts to AI order momentum and forward guidance, secondarily to enterprise-demand signals, and is currently rewarding upside surprises generously — the bar for FY2027 is now high.

Phase C — Judge people & books

Lens 9 · Management

• CEO: Chuck Robbins (Chair & CEO since July 2015, ~11 years). Track record: steered Cisco through the software/subscription transition (software now $22B+, subscription a growing majority of software), ~66 acquisitions on his watch, and grew revenue past $57B with record profitability. He is a capital-allocation operator, not a product visionary — and he correctly (and early) positioned Cisco's owned silicon as the AI differentiator.
• CFO: Mark Patterson (since Jul 27 2025) — 25-year Cisco veteran, prior Chief Strategy Officer and Chief of Staff to the CEO; succeeded Scott Herren (CFO Dec 2020–Jul 2025, retired). A new CFO inheriting the most bullish guidance cycle in a decade is worth watching — he set the "≥$6B AI revenue FY27" marker early in his tenure.
• Capital-allocation history: the defining feature. FY2025 returned $12.43B to holders ($5.995B buybacks + $6.437B dividends) against $14.19B operating cash flow — an ~88% payout of OCF. Over the long run Cisco is a financialization case study (critics at INET and TheStreet note buybacks largely offsetting SBC dilution rather than shrinking the float meaningfully). Buyback yield ~1.63%, ~41% below its 10-yr median. The Splunk deal ($28B, 2024 — largest ever) is the big swing; consensus is overpaid, jury still out, organic Security flat in Q3 FY2026.
• Skin in the game / red flags: Robbins' personal ownership is modest (professional-manager profile, not founder). SBC ~$9.1B TTM, +19.6% YoY — large and growing, the structural dilution that buybacks chase. Strategic AI bets via Cisco Investments include participation in xAI's ~$20B round — sensible optionality or balance-sheet adventurism, depending on your view.
• Archetype: seasoned professional-manager steward running an enormous installed base — exactly the profile that harvests a mature franchise well but is being asked, late-career, to win a hardware land-grab against Arista/Broadcom and the hyperscalers' own silicon teams.

Lens 10 · Forensic Red Flags

Forensic-analyst lens. Every figure labeled.

• Gross margin direction (the real flag): product GM −2.5pp YoY in Q3 FY2026 on mix + memory. AI revenue is dilutive to the blended ~65% gross margin Cisco has historically defended. Watch for non-GAAP adjustments increasingly carrying the EPS story.
• Earnings vs cash divergence: 9-mo FY2026 OCF −12% while EPS +24% — driven by the +$1.54B inventory build and a swing in income-taxes payable (down from $1.857B to $173M current). Explainable (deliberate component pre-buy, tax timing), but a textbook divergence to monitor: if AI orders soften, that inventory is obsolescence risk.
• Tax-rate volatility flattering net income: effective tax 8.3% FY2025 vs 15.6% FY2024 vs 17.7% FY2023; 9-mo FY2026 15.1% vs 5.8% prior-year (which had a $720M discrete benefit). FY2025 net income looked flat (−1%) only because pre-tax income rose and tax fell — net-income comparisons are noisy; use pre-tax/operating income.
• Goodwill & intangibles: goodwill $59.3B and purchased intangibles $7.85B (Q3 FY2026) — roughly half of total assets ($125.5B) is acquisition goodwill, $19.3B of it from Splunk alone. No impairment to date; FY2025 sensitivity showed a hypothetical 10% reporting-unit fair-value decline would not trigger impairment. But a Splunk that stalls organically is the most plausible future impairment.
• SBC vs non-GAAP: ~$9.1B TTM SBC — the gap between GAAP EPS ($0.85) and non-GAAP ($1.06) in Q3 FY2026 is ~25%, materially SBC + intangible amortization. Standard for the sector, but the non-GAAP framing flatters the multiple bulls quote (~17–18x looks cheap on non-GAAP; trailing GAAP is ~37–41x).
• Restructuring: <4,000 jobs (<5% of staff), up to $1B pretax charge ($450M in Q4 FY2026, balance FY2027), refocusing on silicon/optics/security/AI. Recurring restructurings are a Cisco pattern (a near-annual "below-the-line" charge); watch that "non-GAAP" doesn't permanently exclude a recurring cost.

Regulatory findings:

• SEC: No Litigation Releases and no AAERs naming Cisco Systems in the 2021-06-30→2026-06-30 window, per EDGAR EFTS (LR + AAER).
• 10-K Item 3 / Note 21 (company's own disclosure):
• Brazil import-tax matter: Brazilian federal (CY2004–2007) and São Paulo state (CY2005–2007) authorities have assessed the Brazilian subsidiary on a joint-liability theory with an importer for alleged import-tax evasion. Aggregate claims: ~$141M taxes + $816M interest + $289M penalties (≈$1.25B total at the Jul 26 2025 FX rate). Cisco is contesting. This is the single largest disclosed contingency.
• Centripetal Networks patent-infringement litigation (filed Feb 13 2018) — long-running; Cisco has been on the wrong end of large patent verdicts before, so monitor.
• Non-SEC enforcement: Cisco has a history of resolved matters — a 2019 False Claims Act cybersecurity-whistleblower settlement (~$8.6M), and antitrust/counterfeit-trafficking settlements — but no material new agency action (FTC/DOJ/FDA/CFPB) surfaced as of 2026-06-30.
• Bottom line: clean on accounting-enforcement (no SEC LR/AAER); the live legal exposures are a contained Brazil tax contingency and ordinary-course patent litigation. No going-concern or revenue-recognition red flag.

Phase D — Project & stress-test

Lens 11 · Forward Projection (FY2026 / FY2027 / FY2028, fiscal year ends late July)

Built bottom-up from FY2026 guidance + the AI ramp. Cisco's own FY2026 guide: revenue $62.8–63.0B, GAAP EPS $3.16–3.21, non-GAAP EPS $4.27–4.29, AI orders ~$9B, AI revenue ~$4B. I project non-GAAP EPS (the basis consensus and the company guide).

Inputs:

• FY2026 revenue ~$62.9B (midpoint, guided); non-GAAP EPS ~$4.28 (midpoint, guided).
• AI revenue $4B FY2026 → CFO guide ≥$6B FY2027; assume ~$7–8B FY2028.
• Core (ex-AI) revenue ~mid-single-digit growth (enterprise refresh + campus; services flat-to-down).
• Headwind: blended gross margin −50 to −100bps/yr from AI mix + memory until/unless memory normalizes.
• Tailwind: opex leverage + post-restructuring cost base + ongoing buyback (~1.5–2% share reduction net of SBC).

All FY2027/28 figures ****, anchored on the FY2026 guided base and the disclosed AI ramp. At ~$117, the base case = ~24.6x FY2027E non-GAAP / ~22.3x FY2028E. The re-rate has largely happened; from here the return is roughly EPS growth (~11%) + ~1.5% dividend, with the multiple a wildcard tied to whether AI revenue compounds or plateaus.

(Brier forecast forecast.ts create step skipped per --watchlist rules — log only on a committed base case in a /thesis pass. Suggested forecast to log later: "CSCO FY27 non-GAAP EPS ≥ $4.75", p≈0.55, resolves ~2027-07-31.)

Lens 12 · Bull vs Bear

Bull case. Cisco has converted its biggest weakness (a no-growth hardware franchise) into the vehicle for the decade's biggest capex wave. It owns the full stack — Silicon One ASICs, optics, systems, NOS, security, observability — at a moment when hyperscalers want scale-up and scale-across Ethernet fabrics and Robbins is right that silicon ownership is the entry ticket. Orders 0→$2B→~$9B in two years, four hyperscalers growing triple-digits, five P200 design wins, a Stargate seat. Meanwhile the legacy base (RPO $43.5B, sticky services, campus refresh cycle) funds a ~1.5% dividend and buybacks while you wait. At ~24x forward for a re-accelerating mega-cap, it's the cheap way to own AI networking versus Arista at ~44x. Earnings surprise vector: AI revenue recognition outrunning the $4B/$6B guide.

Bear case (permanent-impairment risks). (1) The margin trade is structural, not cyclical — every incremental AI hardware dollar is dilutive to the ~65% gross margin Cisco was valued on; if AI becomes the majority of incremental revenue, blended margins drift toward the high-50s and the "quality" of the franchise degrades even as revenue grows. (2) Hyperscaler insourcing & merchant alternatives — the same four-to-six customers driving the order book are the ones with in-house silicon teams and a Broadcom white-box alternative; AI networking demand is real but Cisco's share of it is the most contestable line in the model. (3) Splunk ($28B, half the goodwill) is growing flat organically — a stalled Splunk is a future impairment and proof the M&A engine still overpays.

Pre-mortem (18 months out, thesis broke): It's late 2027. AI orders "digested" — two hyperscalers pulled in FY2026 demand and went quiet; one moved a fabric to white-box/Broadcom. AI revenue hit $4B FY26 but FY27 came in ~$5B not $6B. Memory costs stayed elevated; blended gross margin fell ~200bps. The stock de-rated from ~24x back toward ~17x as growth proved one-time, and the ATH at $130 marked the top of the AI-networking-rotation trade. Net: flat-to-down 20%.

Are multiples too high? Not egregiously — ~24x forward for ~11% EPS growth + 1.5% yield is fair-to-full, given the AI optionality. But it is no longer cheap: the easy re-rate (14x→24x) is banked. The remaining upside requires the AI franchise to prove durable, which is precisely what's unproven.

Contrarian view (what the market refuses to see): The consensus narrative is "AI-networking trade rotated to the cheap incumbent — Cisco wins." The thing being ignored: Cisco is winning AI revenue by selling its margin. The order numbers are dazzling and the gross margin is quietly compressing in the same filings. The market is extrapolating the order curve while under-pricing the mix shift. If you believe AI networking is a durable Cisco franchise, you should also believe Cisco's gross margin has peaked.

Lens 13 · Devil's Advocate (short-seller)

Dismantling the bull case.

• Revenue concentration where it matters: total revenue has no 10% customer, but the growth — the AI order book — is concentrated in ~4–6 hyperscalers. Those buyers are sophisticated, multi-source by design, and build their own silicon. The single most dangerous fact: your fastest-growing revenue depends on customers structurally incentivized to disintermediate you.
• Most dangerous competitor bulls underestimate: not Arista (visible, premium-priced) — it's Broadcom + the white-box ecosystem. Broadcom is simultaneously Cisco's supplier, and the enabler of the SONiC/white-box stack that lets Google/Meta/Amazon buy merchant silicon and skip the box vendor entirely. Cisco's silicon-as-moat pitch is exactly the argument against paying Cisco's system margins.
• The moat is weaker than bulls think in AI: enterprise switching costs (IOS, certs, SmartNet) do not travel to a hyperscaler buying bare Silicon One + optics. In that arena Cisco competes on price/performance against merchant silicon, which is why the margin is compressing.
• Worst capital-allocation moves: $28B for Splunk (consensus overpaid; flat organic); a decade of buybacks that mostly mopped up ~$9B/yr of SBC dilution rather than compounding per-share value (buyback yield ~1.6%, below median); xAI round participation — using the balance sheet for venture bets.
• Assumptions that must hold for ~$117: (a) AI revenue compounds $4B→$6B→$8B+ without a hyperscaler air-pocket; (b) gross margin compression stays gradual, not cliff-like; (c) the ~24x forward multiple holds. If FY2027 AI/total growth disappoints by 20–30%, base EPS drifts toward the bear ~$4.45 and the multiple compresses to mid-teens → a 30–40% drawdown is on the table. The +32%-in-a-month move into the name is itself a momentum-crowding risk.
• Single permanent-impairment scenario (and plausibility): a major hyperscaler standardizes its AI fabric on in-house/white-box silicon and exits Cisco for new builds. Plausibility: moderate — it's the stated direction of travel for the largest buyers; the question is timing and degree, not whether.

Lens 14 · Management Questions (ordered by information value)

1. Gross margin is the whole debate: at what AI-revenue mix does blended product gross margin trough, and where does it trough — high-50s, low-60s? Quantify the structural (mix) vs cyclical (memory) split of the recent ~250bps product-GM decline.
2. Of the ~$9B FY2026 AI order guide, what share is concentrated in your top 1–2 hyperscalers, and how much of FY2026 demand was pulled forward from FY2027?
3. Which of your top hyperscaler AI customers are also deploying in-house or white-box (Broadcom-based) fabrics today, and how do you retain share as they do?
4. The CFO floated "≥$6B AI revenue FY27" — what's the order-to-revenue conversion assumption, and what would have to happen for FY2027 AI revenue to miss $5B?
5. Splunk Security/Observability is growing flat-to-low-single-digits organically post-consolidation — what's the organic growth target, and at what point would you test the ~$19B of Splunk goodwill for impairment?
6. Inventories rose ~$1.5B on a memory pre-buy; what AI-order level do you need to sustain to avoid an obsolescence write-down on that build?
7. Silicon One has 5 P200 design wins — what's the revenue lag from design win to volume, and what's the attach rate of Cisco optics/systems vs merchant silicon on those wins?
8. How do you defend Silicon One's relevance against Broadcom Tomahawk 5/Jericho economics in scale-out Ethernet, beyond "we own the stack"?
9. Capital allocation: buyback yield is ~1.6% and SBC is ~$9B/yr — what per-share float reduction (net of SBC) should investors expect over the next three years?
10. Services revenue is declining — is the recurring support franchise in secular decline as hardware shifts to hyperscalers, and what offsets it?
11. What is the through-cycle operating-margin target as AI hardware scales, and is the up-to-$1B restructuring sufficient or the first of several?
12. RPO and deferred revenue are flat — is the contracted backlog plateauing, and what does that imply for the durability of subscription growth?
13. Campus/enterprise networking inflected positively in Q3 FY2026 — is that a sustainable refresh cycle (Wi-Fi 7 / AI-ready campus) or a one-time pull-forward?
14. On the Brazil tax matter (~$1.25B aggregate claims) — what's the probable-loss range you're reserved for, and the realistic resolution timeline?
15. What is the single development that would most change your view on the durability of the AI-infrastructure franchise over the next 24 months?
