Approach 1: Zscaler Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model looks at the cash Zscaler is expected to generate in the future and then discounts those projected cash flows back to today, using a required rate of return, to estimate what the stock could be worth now.

Zscaler’s latest twelve month free cash flow stands at about $852.3m. Analysts and Simply Wall St projections point to free cash flow of $1,833.45m in 2030, with interim estimates between 2026 and 2035 ranging from $784.76m to $2,776.60m. Analyst forecasts cover the next few years, while the later figures are extrapolated by Simply Wall St using its 2 Stage Free Cash Flow to Equity model.

On this basis, the model arrives at an estimated intrinsic value of about $212.80 per share, compared with the recent share price of $129.52. That implies an intrinsic discount of roughly 39.1%, which indicates the stock screens as undervalued using this DCF approach.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Zscaler is undervalued by 39.1%. Track this in your watchlist or portfolio, or discover 44 more high quality undervalued stocks.

Approach 2: Zscaler Price vs Sales (P/S)

For companies where investors are focused on revenue rather than profits, the P/S ratio is often the cleaner way to compare what the market is paying for each dollar of sales. It lets you see how the stock is priced relative to its top line without getting caught up in swings in earnings.

Growth expectations and risk still matter a lot. Higher expected growth or lower perceived risk can justify a higher “normal” or “fair” P/S ratio, while slower growth or higher risk usually means a lower one makes more sense.

Zscaler currently trades on a P/S of 6.60x. That is below the peer average of 8.54x but above the broader Software industry average of 3.30x. Simply Wall St’s Fair Ratio for Zscaler is 8.26x. This metric is designed to estimate the multiple that fits the company’s own profile, taking into account factors like its earnings growth, industry, profit margin, market cap and risks, rather than relying only on broad peer or sector comparisons.

Because the Fair Ratio of 8.26x is higher than the current P/S of 6.60x, Zscaler screens as undervalued on this P/S approach.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Zscaler Narrative

Earlier the article mentioned that there is an even better way to understand valuation. This is where Narratives come in, giving you a simple story that sits behind the numbers like fair value, and estimates for future revenue, earnings and margins.

A Narrative is your own clear explanation of what you think is happening at a company. It is linked directly to a financial forecast and then to a fair value that you can compare with the current share price to decide whether the stock looks appealing or stretched for you personally.

On Simply Wall St, Narratives sit inside the Community page and are used by millions of investors as an accessible tool. Each person can set their assumptions, see a fair value, and then quickly compare that value to the live price to help decide whether they are comfortable buying, holding or selling.

For Zscaler, one investor might build a Narrative that lines up with the higher fair value of about US$245.26 and a more optimistic view on AI security and Zero Trust adoption. Another might align with the lower fair value of about US$227.67 or US$238.48 using more cautious assumptions. As news or earnings arrive, the platform updates those Narratives automatically so you can see in real time how fresh information affects your story and valuation.
