Listen to the news

Palo Alto Networks (PANW) is back in focus after management rolled out new AI powered security services and its CEO publicly challenged what he sees as fear driven messaging from major AI labs.

Recent trading has been choppy. The share price slipped 14.04% over the past week and is down 4.53% over the last month. It still carries a 93.52% year to date share price return and a 5 year total shareholder return of 318.41%. This suggests longer term momentum has been strong even as the latest AI announcements and security patch headlines have reset near term expectations around risk and growth potential.

Most Popular Narrative: 12% Undervalued

On the most followed view, Palo Alto Networks carries a fair value of $396.12 against a last close of $347.12. This frames today’s pullback as a discount that leans heavily on its long-term software and subscription story.

The main requirement is that Palo Alto Networks continues to turn platformization, recent acquisitions such as Idira and Chronosphere, and AI-driven offerings like Prisma AIRS and Unit 42 Frontier AI Defense into durable multi-billion dollar ARR pillars, while avoiding margin pressure from higher cloud and hardware costs or stock-based compensation.

See why 385 investors see Palo Alto Networks as 12% undervalued.

Result: Fair Value of $396.12 (UNDERVALUED)

Still, the bullish Palo Alto Networks story depends on clean integration of Idira and Chronosphere, as well as on easing stock-based compensation that currently weighs on reported profitability.

Another View: Palo Alto Networks Through Market Multiples

There is a very different reading of Palo Alto Networks when looking at P/S instead of fair value models. The stock trades at 24.7x sales, compared with 3.8x for the wider US Software group and 18.9x for peers, while the fair ratio sits at 14.7x. That gap points to meaningful valuation risk if sentiment cools or execution stumbles.

Investors weighing this richer P/S profile against the earlier fair value work may want to review what the raw numbers imply for upside or downside skew over time. They can then decide which set of assumptions feels more realistic for their own expectations See what the numbers say about this price — find out in our valuation breakdown.
