Snapshot (price data as of 2026-09-18 close, FMP via Bigdata.com)

FY2026 results (10-K filed 2026-09-03; Q4 call 2026-09-03)

FY27 guidance (Q4 call): revenue $3.908–3.938bn (+16.6–17.5%), ARR $4.396–4.426bn, non-GAAP op margin ~23.7%, FCF margin 23–23.5%, non-GAAP EPS $4.86–4.90, capex ex-software low teens % of revenue (memory prices). Q1 FY27 revenue $935–939m. Restructuring 3% of staff, $30–33m.

Revenue history [background]: FY24 ≈ $2.17bn, FY25 ≈ $2.67bn. Not retrieved this session; consistent with the +25% FY26 growth in the 10-K.

Pipeline scorecard

Lives in scorecard.md next to this file and is updated there; this dossier is a dated snapshot.

S0 detail

1. Distribution lock-in = 1. Installed base >9,400 customers, RPO $7.4bn, ~160 exchanges/200+ data centres peered to major providers (10-K), channel via GSIs and telcos.
2. Unscrapeable data = 1. Inline telemetry, "over 750 billion transaction logs per day" (Chaudhry, Q4 call); physically generated, not on the internet.
3. Liability absorption = 0. Zscaler does not take breach liability onto its balance sheet.
4. Bottleneck = 1 (judgement). Global peered exchange footprint plus government authorisations; the last point is [background] (FedRAMP) and unverified this session.

Surplus: NRR 115% four quarters running, Z-Flex ARR uplift ~30%, gross margin stable at 80% while op margin expands. Third-party complaints of 35%+ renewal increases (dope.security, a competitor's blog) cut both ways: pricing power exists, and it is resented. Falsifier: a hyperscaler or Microsoft bundling SSE into an identity/endpoint suite at zero marginal price, which the 10-K itself flags ("AI technologies may lower barriers to entry ... including large AI providers and hyperscalers"). Chaudhry says Microsoft is "not a meaningful factor" (self-reported, June 2026 conference).

S3: the three biggest risks management itself discloses (10-K FY26)

1. Channel concentration and non-exclusive resellers: top five channel partners 31% of revenue and rising; one partner 13% of receivables.
2. Key-person and sales-leadership turnover: "highly dependent on ... Jay Chaudhry"; "two sales leaders recently departed."
3. Competition intensified by AI lowering entry barriers, including hyperscalers; larger vendors can sell "at zero or negative margins" and bundle.

Also: 2028 converts ($1.725bn, intends cash settlement), international/India exposure, sustained GAAP losses. Red flags checked: no auditor change (PwC), no restatement or going-concern language seen, one CAM (subscription revenue recognition), acquired entities excluded from ICFR audit (0.1% of assets, 4.4% of revenue). SEC comment letters: could not confirm; sec.gov blocked.

S4: value chain in words

Suppliers: memory/storage/processor vendors and colocation (unnamed; component pricing is the disclosed pressure) → Zscaler Zero Trust Exchange (ZIA, ZPA, Zero Trust Branch/Cloud, data security, Security for AI, Agentic SOC with Anthropic/OpenAI models) → channel (GSIs, telcos, VARs, Carahsoft, cloud marketplaces; 31% via top five) → enterprise and federal customers (federal = high single digits of new ACV). Pricing power sits at renewal and in Z-Flex commitments. Competitors named by Morningstar and management: Palo Alto Networks, CrowdStrike, Fortinet, Microsoft; Netskope, Cloudflare, Cisco are [background].

S5: who is on the other side

Insiders: Chaudhry 16.8% plus an 18.2% trustee line (Ajay Mangal; proxy footnote not retrieved). All officers and directors 17.2%. Twelve months of Form 4s show only RSU tax-withholding sales and small 10b5-1 lots; no open-market buys. 13F Q2-26 (WSRA via Bigdata.com): BlackRock +15%, Millennium +237%, Citadel +97%, Jericho Capital and Norges Bank new; T. Rowe cut 63%, Artisan and Westfield exited. 747 holders, 51% institutional per that dataset (Alpha Vantage says 58%). Short interest ~6% of float.

S6: outside-in evidence

• Glassdoor 3.5/5 on 2,550 reviews, down 2% in 12 months; 63% recommend (web search summary).
• G2 4.7/5; Gartner Peer Insights complaints: 10–20% throughput drop, certificate breakage with Docker/npm, ZPA latency, renewal sticker shock.
• Job postings (LinkUp via Bigdata.com): 275 average active, +27% y/y trailing 12 months, despite the 3% cut.
• Oppenheimer (2026-08-19): partner checks "mixed ... broadly tracking in line/better versus partner plans."
• Company-hosted testimonials (Edward Jones, June 2026) are not independent evidence.

S7: draft thesis (not the owner's, not scored)

Bull: organic net new ARR accelerated 7%→10%→17% through FY26 while guidance embeds ~4% net new ARR growth for FY27; if Security for AI and Agentic SOC land, 17% is a floor and the stock re-rates from ~7.7x EV/FY27 revenue. Bear: the acceleration is Q4 renewal seasonality plus Z-Flex pull-forward; new logos have lagged (CFO, Q3 call); Red Canary churn and capex inflation compress FCF; SBC absorbs the whole FCF. Kill criteria: organic net new ARR growth below 10% in any two consecutive quarters; NRR below 112%; Q1 FY27 capex guide above low teens; another senior sales departure before 1H FY27 ends.

S8: valuation frame (owner to decide)

EV ≈ $30.1bn (market cap $31.9bn less $1.77bn net cash). On FY27 guide midpoints: EV/revenue 7.7x, EV/FCF ~33x, non-GAAP P/E ~40x. SBC-adjusted FCF ≈ zero. Scenario sketch: bear FY29 revenue $5.0bn at 5x = $25bn; base $5.6bn at 8x = $45bn; bull $6.2bn at 11x = $68bn. These are illustrative, not a model.

S9: monitoring

Investor Day 2026-10-06; Q1 FY27 2026-11-24; Agentic SOC uptake; geo sales-leader onboarding; Red Canary renewals; memory pricing/capex; 13F Q3-26 for Jericho/T. Rowe; any filed (not "investigated") securities suit; 2028 convert conversion conditions.
