• In its recently reported fiscal third quarter 2026, Zscaler posted US$850.48 million in sales, higher year on year, but its net loss widened and the company cut its full-year free cash flow margin guidance while modestly raising revenue guidance to about US$3.33 billion.
• At the same time, Zscaler highlighted strong momentum in AI-focused security products and new alliances, even as higher costs and senior sales departures raised questions about the durability of its execution.
• We’ll now examine how Zscaler’s stronger revenue guidance but lower free cash flow outlook could reshape the company’s Zero Trust AI investment narrative.

Capitalize on the AI infrastructure supercycle with our selection of the 47 best 'picks and shovels' of the AI gold rush converting record-breaking demand into massive cash flow.

Zscaler Investment Narrative Recap

To own Zscaler, you need to believe its Zero Trust and AI security platforms can keep gaining share despite heavy competition and ongoing losses. The latest quarter reinforced that demand story through stronger revenue guidance, but the sharply lower free cash flow margin outlook and rising costs make execution the key short term catalyst and risk, especially after the stock’s sharp pullback and recent senior sales departures.

Project AI Guardian, Zscaler’s new collaboration with major global system integrators, looks particularly relevant here. It ties the company’s AI Protect portfolio directly into large consulting partners that help shape enterprise AI security spending, aligning with the current catalyst around AI driven security budgets while also putting more pressure on Zscaler to convert this technical and channel momentum into more efficient growth and healthier free cash flow.

Yet beneath the AI excitement, investors should also be aware that...

Zscaler's narrative projects $5.2 billion revenue and $152.9 million earnings by 2029. This requires 19.9% yearly revenue growth and a $220.5 million earnings increase from -$67.6 million today.

Uncover how Zscaler's forecasts yield a $227.67 fair value, a 80% upside to its current price.

Exploring Other Perspectives

Some of the lowest ranked analysts were already cautious, assuming revenue would grow about 19.7 percent a year and no profits within three years, so this cut to free cash flow margins and higher AI infrastructure spend could push their more pessimistic view on execution risk even further, which is why it is worth comparing how differently people can read the same numbers before you decide where you stand.
