Palo Alto proves its strength—but the road ahead just got steeper

Key points:

• Palo Alto delivered strong fourth-quarter results, beating expectations with 16% revenue growth, record margins, and a solid outlook for 2026.
• The USD 25 billion CyberArk acquisition could expand Palo Alto’s reach into identity security but introduces integration risk and shareholder dilution.
• With co-founder and CTO Nir Zuk retiring, leadership continuity and execution will be critical as competition from rivals intensifies.

Strong numbers in a nervous market

Palo Alto Networks’ latest earnings report landed at a delicate moment for the cybersecurity giant. Investors were still digesting its bold USD 25 billion bid for identity-security specialist CyberArk—a deal that sparked concerns over dilution and execution risk. Against that backdrop, Palo Alto’s fiscal fourth-quarter results offered a welcome reminder of the company’s core strength: consistent execution in a market where demand shows no sign of slowing.

Revenue rose 16% year-on-year to USD 2.54 billion, just ahead of consensus, while adjusted earnings per share came in at USD 0.95—beating estimates comfortably. Free cash flow hit USD 935 million in the quarter, maintaining a strong 38% margin. Shares jumped about 5% in after-hours trading as the results eased concerns around the CyberArk deal and reassured investors about Palo Alto’s growth trajectory, while CyberArk stock also popped on the news.

“In a market full of noise, Palo Alto’s message is simple: the growth engine is still firing on all cylinders.”

What’s driving growth? Platformisation, software and AI

The standout theme in Palo Alto’s results is platformisation. The company continues to sign record numbers of large, multi-product deals, consolidating point solutions into an integrated security platform. Customers with USD 5–10 million in annual recurring revenue grew nearly 50% year-on-year, while mega deals above USD 20 million nearly doubled.

Product revenue climbed 19% year-on-year, driven by software firewalls, which now account for more than half of product sales. Subscription revenue rose 17%, and support revenue increased 11%.

AI is emerging as another accelerant. AI-related annual recurring revenue reached USD 400 million, more than doubling from a year earlier, with Cortex XSIAM—the firm’s AI-driven security operations tool—growing over 200%. Palo Alto cited a surge in generative AI traffic and a parallel rise in AI-related security incidents as powerful demand drivers.

“AI isn’t just reshaping the threat landscape—it’s rewriting the economics of cybersecurity.”

Upbeat outlook into 2026

Management guided for fiscal 2026 revenue of USD 10.48–10.53 billion, representing 14% growth and comfortably ahead of consensus. Adjusted EPS is expected to land between USD 3.75 and USD 3.85, again beating expectations. For the coming quarter, Palo Alto’s revenue and EPS expectations were also slightly above forecasts.

Importantly, free cash flow margins are projected to remain in the 38–39% range, underscoring operational discipline even as the company invests heavily in growth.

“Strong growth with stable margins is the holy grail in software—and Palo Alto is hitting both targets.”

Risks on the horizon: CyberArk deal and CTO exit

While the earnings beat reassured investors, two clouds hang over Palo Alto.

The first is its planned USD 25 billion acquisition of CyberArk, a leader in identity security. Strategically, the move makes sense: identity is the missing piece in Palo Alto’s network, cloud and endpoint security platform. But the deal is large and dilutive. CyberArk holders will receive cash and Palo Alto shares, increasing the outstanding share count by more than 13%.

Execution risk is real. Integration challenges could distract management at a time when competition is intensifying. Microsoft and Okta dominate identity, CrowdStrike is expanding into adjacent areas, and Fortinet remains strong in firewalls. Palo Alto’s edge lies in bundling, but hyperscalers are pushing deeper into cybersecurity with their own cloud-native offerings.

The second risk is leadership change. Co-founder and CTO Nir Zuk has retired, handing the reins of product strategy to long-time executive Lee Klarich. While Klarich is well regarded, Zuk’s departure removes a visionary voice from Palo Alto’s innovation engine.

“CyberArk could complete the puzzle—or it could trip Palo Alto mid-race.”

Valuation: premium pricing, execution required

At around USD 185 post-earnings, Palo Alto trades at roughly 46 times forward earnings and 11 times sales. Those are premium multiples, reflecting its growth profile and margin strength, but they leave little room for error. By contrast, Fortinet trades on lower multiples despite high profitability, while CrowdStrike is valued on faster top-line growth. Palo Alto sits in between—priced for both growth and stability.

Investors must weigh whether Palo Alto can deliver on its ambitious target of sustaining 40% free cash flow margins by fiscal 2028—particularly with CyberArk folded in.

“At today’s valuation, Palo Alto has to run fast just to stand still.”

What investors should watch

1. CyberArk integration – Can Palo Alto unlock cross-sell synergies without distracting from core execution?
2. AI-driven products – Will Cortex XSIAM and other AI-enabled offerings keep scaling at triple-digit growth rates?
3. Margin discipline – Can management maintain strong margins while absorbing a USD 25 billion deal?
4. Competitive pressure – Will hyperscalers, Fortinet, CrowdStrike and Okta erode Palo Alto’s advantage in bundling?
5. Leadership transition – Can Klarich sustain the innovation pace after Zuk’s departure?

“The story is less about whether Palo Alto can grow—it’s about whether it can keep the lead in an arms race where rivals are sprinting too.”

A strong hand, but higher stakes

Palo Alto delivered a quarter that reassured investors, beat expectations, and pointed to another year of strong growth. But the true test lies ahead. The CyberArk acquisition is bold and potentially transformative, yet it amplifies execution risk at a time of leadership transition.

For investors, Palo Alto remains one of the strongest names in cybersecurity—an industry with powerful secular tailwinds. But at current valuations, the margin for error is thin.
