Approach 1: Zscaler Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model projects a company’s future cash flows and then discounts them back to today’s value, aiming to estimate what the business could be worth based on those projected cash streams.

For Zscaler, the model uses last twelve month Free Cash Flow of about US$876.3 million and a 2 Stage Free Cash Flow to Equity approach. Analysts provide detailed forecasts for the next few years, with Simply Wall St extrapolating out to 2035. Within those projections, Free Cash Flow is expected to reach US$2.0b in 2030, with intermediate years between 2026 and 2035 ranging from roughly US$898.4 million to US$3.0b before discounting.

After discounting these projected cash flows back to today, the model arrives at an estimated intrinsic value of US$239.64 per share. Against the recent share price of US$182.37, this implies the stock is about 23.9% below the DCF estimate. Based on these cash flow assumptions, the model frames Zscaler as trading at a discount.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Zscaler is undervalued by 23.9%. Track this in your watchlist or portfolio, or discover 48 more high quality undervalued stocks.

Approach 2: Zscaler Price vs Sales

For companies where investors focus heavily on revenue rather than profits, the P/S ratio is a useful way to think about valuation because it compares what you pay for each dollar of sales with what similar businesses trade on.

Higher expected growth and lower perceived risk usually justify a higher “normal” P/S multiple, while slower growth or higher risk tend to pull that multiple down. So context really matters when you compare Zscaler’s P/S with other software stocks.

Zscaler currently trades on a P/S of 9.77x, compared with the broader Software industry average of 3.73x and a peer group average of 8.59x. Simply Wall St’s Fair Ratio for Zscaler is 9.25x, which is a proprietary estimate of what the P/S might be given factors such as the company’s earnings growth profile, profit margins, industry, market cap and key risks.

The Fair Ratio is more tailored than a simple peer or industry comparison because it adjusts for those company specific drivers rather than assuming all businesses deserve the same multiple. With Zscaler’s actual P/S only modestly above the 9.25x Fair Ratio, the stock screens as slightly expensive on this measure.

Result: OVERVALUED
