# Zscaler: $779 million of free cash flow, $822 million of stock pay ZS, NASDAQ. Published September 25, 2026. Price as of the September 24, 2026 regular session close. ## Verdict: HOLD at $214.64 (do not add) Do not add. Zscaler is a high-quality security platform, but the shares trade about 31% above the Base value once stock compensation is treated as a real cost. The two valuation methods diverge sharply, so a 40% margin of safety is required and the buy zone starts at $98.58. - Bear value: $148.40 - Base value: $164.30 (downside 23.5%) - Bull value: $243.49 - Expected value (25/50/25 weighting): about $180.12 - Required margin of safety: 40% - Maximum buy price: $98.58 - EV to fiscal 2027 revenue: about 8.5x - Free cash flow after stock compensation, fiscal 2026: about -$43 million - Business quality: 79/100 - Valuation score: 30/100 - Confidence: 18/25, grade B Zscaler is one of the leaders in Zero Trust security: companies route their users' and applications' traffic through its cloud instead of through firewalls. The business is excellent, with 25% growth, 80% gross margins and huge contracted revenue. But in fiscal 2026 it paid its employees $822 million in stock, more than the $779 million of free cash flow it reported. For shareholders, that changes the math. At $214.64 on September 24, 2026, the shares trade 30.6% above my triangulated Base value of $164.30, a downside of 23.5% to Base. Even the Bear value of $148.40 is below the price, and only the Bull value of $243.49 is above it. The required margin of safety of 40% puts the maximum buy price at $98.58. For existing holders this is a hold. New money should not add at this price. Route: SF-07 SaaS and technology growth, cloud-native cybersecurity subscription platform. Economic classification: Quality Growth (8/12, capped because of stock compensation and dilution). Primary method: forward EV to fiscal 2028 revenue. Secondary methods: free cash flow after stock compensation, and a growth-normalized historical reference. Zscaler's fiscal year ends in July. Values are present fair-value estimates, not 12-month price targets. ## What Zscaler is Zscaler runs a global cloud that inspects and secures traffic between users, devices, applications and the internet. Customers subscribe, so revenue is recurring and highly visible. The platform is expanding from user security into workloads, branches, data security, AI security and security operations. The acquisition of Red Canary added $141 million of annual recurring revenue in fiscal 2026; without it, ARR growth was about 20% rather than the reported 25%. ## Fiscal 2026 results and guidance | Fiscal year to July | Revenue | | --- | --- | | 2022 | $1.09 billion | | 2023 | $1.62 billion | | 2024 | $2.17 billion | | 2025 | $2.67 billion | | 2026 | $3.35 billion | | 2027 guidance midpoint | $3.92 billion | In fiscal 2026, revenue and ARR both grew 25%, ARR reached $3.771 billion, remaining performance obligations rose 27% to $7.365 billion and customers above $1 million of ARR rose 18% to 785. GAAP operating loss was $133.3 million; non-GAAP operating income was $767.1 million. Fiscal 2027 guidance calls for revenue of $3.908 to $3.938 billion, about 17% growth, ARR of $4.396 to $4.426 billion and a free cash flow margin of 23.0% to 23.5%. ## Stock pay versus free cash flow | Fiscal year | Stock-based compensation | | --- | --- | | 2024 | $527.7 million | | 2025 | $661.4 million | | 2026 | $821.9 million | Fiscal 2026 free cash flow was $779.1 million, a 23% margin. Stock compensation was $821.9 million, about 24.5% of revenue. Free cash flow after stock compensation was therefore about **-$43 million**, or roughly -1% of revenue. That does not mean the business lacks value. It means investors cannot count the full headline free cash flow while ignoring the equity transferred to employees, which is why the framework's hard metric for software companies is free cash flow after stock compensation. ## Cash, debt and shares Cash and short-term investments were $3.474 billion against $1.725 billion of convertible notes due 2028, which have capped calls to limit dilution, so net cash is about **$1.75 billion**. Shares outstanding were 163.1 million on August 27, 2026, but fiscal 2027 guidance assumes about 173 million fully diluted shares, which the valuation uses. At $214.64, market value is about $35.0 billion and enterprise value about $33.2 billion. ## Primary valuation: forward EV to revenue | Scenario | Fiscal 2028 revenue | Growth vs 2027 guidance | EV to revenue | Value per share | | --- | --- | --- | --- | --- | | Bear | $4.35 billion | 11% | 5.5x | $148.40 | | Base | $4.57 billion | 16.5% | 6.7x | $187.10 | | Bull | $4.75 billion | 21% | 8.5x | $243.49 | After $1.75 billion of net cash and 173 million shares, the primary Base value is **$187.10**. The Base assumes growth continues near the guided 17%, not an acceleration. The 6.7x multiple is well below Zscaler's historical premium because growth is slowing and stock compensation is high. ## Secondary valuation: free cash flow after stock compensation Because today's free cash flow after stock compensation is near zero, this method values a more mature year. Revenue grows 15% a year to about $5.97 billion in fiscal 2030. The headline free cash flow margin rises to 27% and stock compensation falls to 13% of revenue, about half today's level, leaving a hard free cash flow margin of 14%, or about $835 million. At 30x, plus net cash, and divided by 173 million shares, that gives about $155 per share in fiscal 2030, or **$116.42** today discounted at 10% a year. These are estimates, and fairly generous ones: they assume stock compensation halves as a share of revenue. ## Historical cross-check Zscaler trades at about 10.6x trailing EV to sales and about 41x headline price to free cash flow, against an estimated five-year average near 14.9x sales. That average came with much faster growth and is not automatically fair today. A growth-normalized historical reference gives about **$200**, with low weight. ## Valuation triangulation | Method | Base value | Weight | | --- | --- | --- | | Forward EV to revenue at 6.7x | $187.10 | 50% | | Free cash flow after stock compensation | $116.42 | 35% | | Growth-normalized historical reference | $200.00 | 15% | | Triangulated Base | $164.30 | 100% | The primary and secondary methods diverge by about 47%, far above the framework's 30% threshold. The flag is raised, confidence is lowered and the margin of safety rises. The divergence is the core finding: on revenue, Zscaler looks roughly fairly priced; on cash left for shareholders after stock pay, it looks expensive. The secondary and historical methods exist only for the Base case, so the Bear and Bull values come from the primary method alone. ## What is the market already pricing in? Enterprise value of about $33.2 billion is about 8.5x fiscal 2027 revenue guidance. The price requires high-teens ARR and revenue growth, about 80% gross margins, further operating leverage, a free cash flow margin of 23% or more, successful AI, data and security operations products and, above all, stock compensation that grows much more slowly than revenue. If growth falls toward the low teens without better owner earnings, the multiple is hard to defend. ## Bear, base and bull scenarios | | Bear | Base | Bull | | --- | --- | --- | --- | | Probability | 25% | 50% | 25% | | Fiscal 2028 revenue | $4.35 billion | $4.57 billion | $4.75 billion | | EV to revenue | 5.5x | 6.7x | 8.5x | | Value per share | $148.40 | $164.30 | $243.49 | | vs $214.64 | -30.9% | -23.5% | +13.4% | **Bear:** growth slows to about 11% and the multiple compresses; recurring revenue and net cash limit the damage. **Base:** growth near the guided 17% and gradually better owner earnings. **Bull:** AI security and new products reaccelerate growth above 20% and the market keeps paying a premium. The probability-weighted value is **$180.12**, 16.1% below the price. ### Sensitivity: primary value per share | Fiscal 2028 revenue \ EV to revenue | 5.5x | 6.7x | 8.5x | | --- | --- | --- | --- | | $4.35 billion | $148.40 | $178.58 | $223.84 | | $4.57 billion | $155.40 | $187.10 | $234.65 | | $4.75 billion | $161.12 | $194.07 | $243.49 | ## How the buy price is set Confidence B starts at a 30% margin of safety. Five points are added for stock compensation and dilution and five for the valuation divergence, for 40%. A 40% discount to the $164.30 Base gives a **maximum buy price of $98.58**. ## Dividend Zscaler pays no dividend. ## Reasons to own ZS - **Zero Trust leadership.** A leading position with real switching costs for large enterprises. - **Visibility.** $3.771 billion of ARR and $7.365 billion of contracted future revenue. - **Quality growth.** Revenue and ARR both grew 25% in fiscal 2026, with about 80% gross margins. - **A wider market.** AI security, data security, security operations, workload and branch products expand what Zscaler can sell. - **Net cash.** About $3.5 billion of cash and short-term investments. ## What could go wrong? - **Stock compensation.** Fiscal 2026 stock pay exceeded headline free cash flow. If it keeps growing with revenue, per-share value creation stalls. This is the main thesis breaker. - **Slowing growth.** Guidance points to about 17% in fiscal 2027, and part of recent ARR growth came from an acquisition. - **Valuation.** About 8.5x forward revenue requires premium execution. - **Competition.** Palo Alto Networks, CrowdStrike, Cloudflare, Microsoft and others compete for consolidating security budgets. - **Execution.** New products and AI must offset maturing seat-based growth; a new chief revenue officer starts on October 1, 2026. ## Management execution Revenue and ARR grew 25%, Q4 non-GAAP operating margin reached 24%, contracted revenue grew 27% and large customers grew 18%. The main caveat is persistently high stock compensation and reliance on non-GAAP profitability. Management credibility scores **16/20**, good. ## Stock Analyza scorecard | Business quality | Score | | --- | --- | | Moat and platform | 18/20 | | Economic return | 13/20 | | Balance sheet | 14/15 | | Cash flow quality | 10/15 | | Growth and runway | 13/15 | | Management and capital allocation | 8/10 | | Dilution and governance | 3/5 | | Total | 79/100 | The valuation score is **30/100**: the price is well above Base, even the Bear value is below it, and the methods diverge sharply. | Economic classification | Points | | --- | --- | | Economic return | 1/2 | | Revenue and ARR growth | 2/2 | | FCF per share | 1/2 | | Balance sheet | 1/1 | | Unit economics | 1/1 | | Recurring revenue | 2/2 | | Reinvestment runway | 1/2 | | Raw 9/12, capped for stock compensation: Quality Growth | 8/12 | ## Confidence score | Confidence | Score | | --- | --- | | Data quality | 5/5 | | Business predictability | 4/5 | | Valuation robustness | 2/5 | | Accounting transparency | 3/5 | | Scenario dispersion | 4/5 | | Total | 18/25, grade B | ## What I would watch from here ### Green - Revenue and ARR growth of 17% or more - Contracted revenue growth of 20% or more - Non-GAAP gross margin of 79% or more - Free cash flow margin of 23% or more - Stock compensation below 70% of free cash flow - Diluted share growth below 3% a year - $1 million ARR customers growing 15% or more ### Yellow - Revenue and ARR growth of 14% to 17% - Contracted revenue growth of 12% to 20% - Gross margin of 77% to 79% - Free cash flow margin of 20% to 23% - Stock compensation at 70% to 100% of free cash flow - Share growth of 3% to 6% ### Red - Revenue or ARR growth below 14% - Contracted revenue growth below 12% - Gross margin below 77% - Free cash flow margin below 20% - Stock compensation persistently above free cash flow - Share growth above 6% The next review points are the Investor Day on October 6, 2026 and Q1 fiscal 2027 results. The Investor Day is where a stock compensation target would matter most. ## The three most important thesis breakers 1. ARR and revenue growth below the mid-teens. 2. Stock compensation staying above free cash flow without offsetting per-share growth. 3. Free cash flow margin falling below 20%. ## Adversarial review The first draft had the right diagnosis, that stock compensation consumes all of the headline free cash flow, but its valuation did not follow through. Four corrections were made. Its primary values were rounded up: at its own inputs, the Base is $194.07, not $196, and the Bull $263.14, not $266, and several sensitivity cells were $1 to $2 too high. Its Base revenue of $4.75 billion implied 21% growth in fiscal 2028, an acceleration, while the text described slowing growth; it now assumes 16.5%, close to guidance. Its secondary value of $190 was labeled dilution-aware but had no stated inputs, and it was barely below the primary value, although the draft itself showed free cash flow after stock compensation near zero. It was rebuilt transparently at $116.42. Finally, the draft's twelve-month price-touch probabilities were dropped as not part of the framework. The Base moved from $195 to $164.30, the maximum buy price from $126.75 to $98.58 and the Bull from $265 to $243.49. The verdict remains hold, now with a clear instruction not to add. The strongest counter-argument is that Zscaler combines about 20% organic ARR growth, 80% gross margins, a 23% free cash flow margin and strong contracted revenue, and that the market has long paid premium multiples for exactly that. The answer is that shareholders own the business after the stock paid to employees, and on that measure the price already assumes stock compensation falls sharply. | Robustness test | Base value | | --- | --- | | Base | $164.30 | | The draft's Base revenue of $4.75 billion | $167.78 | | The draft's secondary value of $190 | $190.05 | | Stock compensation at 10% of revenue by 2030 | $172.46 | | Hard free cash flow at 35x | $170.65 | | Discount rate 8% instead of 10% | $166.60 | Only by reverting to the draft's opaque secondary value does the Base approach $190, and even then it stays below the price. The publication gate status is PASS\_WITH\_WARNING: owner earnings normalization, and above all the future path of stock compensation, remain the main uncertainty. ## Final verdict: hold at $214.64, do not add Zscaler is a high-quality recurring revenue security platform, but stock compensation currently consumes all of its headline free cash flow, and the price assumes that changes. **Verdict: HOLD at $214.64, do not add. Triangulated Base value $164.30, downside 23.5%, Confidence B (18/25). Required margin of safety 40%, maximum buy price $98.58.** For an existing holder, business quality supports holding, though a position well above Base value deserves a sizing review. New money waits for $98.58 or below, or for clear evidence that stock compensation is falling relative to free cash flow. The main thesis breaker is failure to maintain high-teens recurring growth while stock compensation stays near or above headline free cash flow. ## More analyses on Patreon This analysis is free.
