Beating The Bull begins coverage of Palo Alto Networks with a Watchlist rating and an investment score of 68 out of 100. The shares closed at $374.74 on 25 September. The probability-weighted fair value is $355, about 5% below the price, and the level at which the stock becomes interesting is about $300.

Is this the best business in security? On most measures, yes. Fiscal 2026 revenue rose 24% to $11.48 billion, next-generation security ARR climbed 63% to $9.1 billion, and the company added nearly $1 billion of net new ARR in the July quarter alone. It signed a record of about 220 net new platformization deals, and adjusted free cash flow reached $4.41 billion, a 38.4% margin. Newer products are scaling fast: XSIAM ARR passed $700 million and Prisma AIRS, its AI security line, passed $100 million within four quarters.

So why not buy it? Because the fiscal 2027 outlook shows how little of that growth reaches earnings per share. Revenue is guided up 23-24%, but non-GAAP EPS is guided to $4.16-4.19, only about 9% higher. The CyberArk deal, which closed in February, was paid partly in stock, lifting the diluted share count to 844-847 million. Cloud-hosting costs are growing faster than revenue, and memory prices are squeezing the hardware line. Gross margin fell 100 basis points in the fourth quarter to 74.8%.

How much growth is organic? Less than the headline suggests. CyberArk and Chronosphere are not fully lapped until the second half of fiscal 2027. Adjusting fiscal 2026 for a full year of both, underlying growth is roughly 14% on this report’s estimate.

What is the market paying? About 90 times guided earnings and 56 times forward free cash flow. The stock has risen about 160% from its February low, mostly through a higher multiple. The base case, which capitalises fiscal 2028 free cash flow of about $6.4 billion at 45 times, is worth about $350. A bull case with faster organic growth reaches $501. A bear case at 30 times free cash flow lands at $219, roughly 42% below the current price.

What would change the view? A pullback toward $300 would put the stock near 72 times fiscal 2027 earnings, with about 17% upside to the base case. First-quarter results, expected in mid-to-late November, could also shift the picture if EPS beats guidance while gross margin holds steady.

The company is executing about as well as anyone in the sector. The price already reflects it.
