Palo Alto Networks Beats Q4 Estimates as AI-Driven Cyber Threats Fuel Demand

Palo Alto Networks surpassed fiscal fourth-quarter estimates on Tuesday, reporting $3.41 billion in revenue against analyst expectations of $3.35 billion, as the rapid proliferation of AI-powered cyberattacks drives customers toward newer, more capable security tools.

Earnings per share came in at $1.02 adjusted, topping the 98-cent consensus estimate. Revenue jumped 34% year over year, up from $2.54 billion in the same period a year ago. The company also reported a net loss of $282 million, or 35 cents per share, a swing from net income of $254 million, or 36 cents per share, in the prior-year quarter.

Shares dipped roughly 2% in extended trading following a 5% decline during the regular session.

For the first quarter of the new fiscal year, Palo Alto forecast revenue of $3.30 billion to $3.31 billion, above the analyst estimate of $3.22 billion. The company's full-year guidance called for revenue between $14.10 billion and $14.20 billion, and adjusted earnings per share of $4.16 to $4.19 — both ahead of Wall Street's projections of $13.79 billion and $4.11, respectively.

CEO Nikesh Arora framed the results as early confirmation of a long-cycle opportunity. "This is a long-term tailwind," Arora told reporters. "It will not happen in one quarter, and it will not happen in two. It just underpins the long-term duration from a growth rate perspective for our business."

On Palo Alto's earnings call, Arora put a dollar figure on the scale of the challenge. "There's approximately $1 trillion of global cybersecurity debt that must be modernized to defend against automated threats because they operate instantaneously," he said. He added that nothing deployed seven to 10 years ago is equipped to handle AI operating at machine speed, arguing that companies must fundamentally rethink their security architecture.

Arora credited Anthropic's Mythos model — released earlier this year — as a turning point in how enterprises perceive AI-related cyber risk. The model's ability to identify and exploit software vulnerabilities, he said, accelerated customer urgency in a way that years of industry warnings had not. "I've been trying for eight years to tell customers they're not ready, and [Anthropic CEO Dario Amodei] did it in one event, just by launching Mythos," Arora told CNBC's Jim Cramer on "Mad Money."

The company said it has now held over 2,000 customer briefings related to its Frontier AI Critical Defense Program, up from roughly 1,200 disclosed last quarter. The initiative, formally introduced in August, uses advanced AI models to probe customer defenses, surface vulnerabilities, and guide infrastructure modernization.

Alongside its earnings, Palo Alto announced the acquisition of AI agent startup Console, extending an aggressive dealmaking campaign. In just over a year, Arora has overseen the $25 billion purchase of identity security firm CyberArk and a nearly $3.4 billion deal for Chronosphere, among others.

Palo Alto is not alone in benefiting from increased enterprise security spending. CrowdStrike and Okta both reported upbeat earnings and guidance last week, as customers broaden their investments across the cybersecurity stack. Agentic AI concerns have intensified following incidents such as the OpenAI-Hugging Face hack, which illustrated how AI agents can plan and orchestrate attacks with growing autonomy.

Shares of Palo Alto have nearly doubled in 2026 — and have surged 113% since April 7 — reflecting a sharp reversal in market sentiment. Earlier in the year, investors had penalized cybersecurity stocks on fears that capable AI models would undercut demand for traditional security software. That thesis has since given way to the view that the same technology amplifying attacker capabilities also extends the industry's growth runway.

Arora cautioned against expecting the modernization wave to translate into immediate revenue windfalls. "Not everything's going to happen next quarter," he told Cramer. "But all I say is this changes the long-term growth rate and duration of cybersecurity, not just for Palo Alto, but as an industry."
