Simply Wall St · 1d ago

Why Palo Alto Networks Is Back in the Spotlight

Palo Alto Networks (PANW) is drawing attention after being added to the S&P 100, shortly after reporting quarterly earnings that combined strong revenue growth and guidance with a reported net loss.

The company posted fourth quarter revenue of US$3.41b compared with US$2.54b a year earlier, while shifting from net income of US$254m to a net loss of US$282m over the same period.

For the full year to July 31, 2026, Palo Alto Networks reported revenue of US$11.48b versus US$9.22b previously, with net income of US$307m compared with US$1.13b a year earlier.

Alongside these results, management issued guidance for fiscal 2027 that points to expected total revenue of US$3.30b to US$3.31b in the first quarter and US$14.10b to US$14.20b for the full year.

Palo Alto Networks' recent S&P 100 inclusion and acquisition of Console have arrived during a period of sharp share price swings. The stock is down 12.79% over the past week and 8.41% over the past month, yet its 27.92% 90 day share price return and 85.79% year to date share price return suggest momentum has been strong overall. The 68.84% 1 year and 319.97% 5 year total shareholder returns highlight how the long term story has so far rewarded investors who stayed invested through volatility.

Most Popular Narrative: 1% Undervalued

On the most followed narrative, Palo Alto Networks' fair value of $336.70 sits only slightly above the last close at $333.26. This puts the focus firmly on the assumptions behind that small gap.

Ongoing industry consolidation, as enterprises seek to simplify and maximize the effectiveness of their security stack, has strengthened the trend towards platformization. This has resulted in larger multi-platform deal sizes, improved cross-sell, higher net retention rates (120%), and near zero churn among platformized clients, all of which support future margin expansion and earnings growth.

Another View on Palo Alto Networks Valuation

While the main Palo Alto Networks narrative leans on fair value of about $336.70, the current P/S ratio tells a tougher story. The stock trades at 23.7x sales compared with 18.1x for peers and 4x for the wider US Software industry, and above an estimated fair ratio of 14.9x.

That gap implies investors are paying a sizeable premium today, which can work out well if growth and margins match the bullish narrative but can hurt quickly if expectations cool. Is that premium a risk you are comfortable underwriting, or a price you would rather let others pay first?
