Approach 1: Zscaler Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a company could be worth by projecting its future cash flows and then discounting those back to today’s dollars. It essentially asks what that stream of cash is worth right now.

For Zscaler, the model uses a 2 Stage Free Cash Flow to Equity approach, starting from last twelve months free cash flow of about $876.3 million. Analysts have provided free cash flow estimates for the next several years, and Simply Wall St extends those projections, with free cash flow for 2030 estimated at about $2.0b, all expressed in US$ terms.

When these projected cash flows from 2026 through 2035 are discounted back and combined, the model arrives at an estimated intrinsic value of about $233.89 per share. Compared with the recent share price of $122.23, this DCF output suggests the stock trades at roughly a 47.7% discount, which indicates potential upside if the projections and assumptions hold.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Zscaler is undervalued by 47.7%. Track this in your watchlist or portfolio, or discover 62 more high quality undervalued stocks.

Approach 2: Zscaler Price vs Sales

For a business that is still focused on building scale, the P/S ratio can be a useful way to think about value because it compares what the market is paying today with each dollar of current revenue, without relying on earnings that may be affected by heavy investment.

What investors are really weighing is how much growth and risk are already baked into that multiple. Higher expected growth or lower perceived risk can justify a higher P/S ratio, while slower growth or higher risk tends to support a lower, more cautious multiple.

Zscaler currently trades on a P/S ratio of 6.55x. That sits above the Software industry average of 3.42x and also above the peer group average of 5.93x, so on simple comparisons the shares trade at a premium.

Simply Wall St’s Fair Ratio for Zscaler is 7.71x. This is a proprietary estimate of what the P/S might be, given the company’s earnings growth outlook, industry, profit margins, market cap and risk profile. It can be more informative than a basic peer or industry comparison because it adjusts for company specific characteristics instead of treating all software names as identical.

Comparing the Fair Ratio of 7.71x with the current P/S of 6.55x suggests the shares are trading below that modelled level.

Result: UNDERVALUED
