Palo Alto Networks (PANW)’s AI Growth Faces a Higher Valuation Bar

Palo Alto Networks (PANW) is experiencing strong momentum in its fiscal 2027, particularly in its next-generation security (NGS) segment. However, the company's stock has rallied sharply, leading investors to demand more from the cybersecurity firm. PhillipCapital downgraded the stock to Neutral from Accumulate and raised the price target to $346 from $320, stating that while Palo Alto's opportunities are compelling, the stock's 160% rise from its February low to its August peak has raised the bar for further gains.

The company's revenue grew 34% year-over-year to $3.4 billion in the fiscal 2026 fourth quarter, and NGS ARR surged 63% to $9.10 billion, with nearly $1 billion of net new NGS ARR added in the quarter. Over 65% of Palo Alto's NGS ARR comes from platformized customers. The company also expects AI to expand the addressable market, with Palo Alto offerings such as Prisma AIRS and Cortex assisting in addressing emerging needs.

However, the growth rate is expected to slow, with NGS ARR growth projected at 22%-23% for fiscal 2027, down from 63% growth in the end of fiscal 2026. Revenue growth is also expected to decelerate, with growth rates of 23%-24% compared to nearly 25% in fiscal 2026.
