In Q4 (May–July 2026), Palo Alto Networks completed the Portkey acquisition ($117M, AI Gateway capabilities enhancing Prisma AIRS) on May 29 and signed definitive agreements for Embrace Mobile ($325M, Real User Monitoring for the observability platform) on July 20 and Console Systems ($500M, agentic workflows for Cortex) on July 29; both latter deals closed after fiscal year-end (August 27 and September 1, 2026). Annual context: fiscal 2026 included six acquisitions totaling approximately $25.5B in consideration, anchored by the $21.1B CyberArk deal (February 2026, forming the Idira identity security platform) and $3.0B Chronosphere deal (January 2026, forming the observability platform).
Prisma AIRS Gateway reached general availability on July 16, 2026 (Q4), incorporating Portkey's AI gateway capabilities into the AI security platform for governing AI agents, securing AI coding tools, and inspecting LLM traffic. Annual context: fiscal 2026 product introductions also included PAN-OS 12.1 Orion, Prisma AIRS 2.0 and 3.0, Next-Gen Trust Protection (NGTS), and Unit 42 Frontier AI Defense services (launched April 2026) to help customers neutralize threats from next-generation AI models.
Annual (fiscal 2026) operating metrics: total revenue $11.5B (+24% YoY); NGS ARR $9.1B (vs. $5.6B a year prior); remaining performance obligations $21.2B (vs. $15.8B); subscription and support 80.1% of revenue; gross margin 70.4% (down from 73.4%); operating margin 6.1% (down from 13.5%); net income $307M. Q4-specific: the company disclosed supply chain disruption during the fourth quarter, including increased memory and component costs from a global memory shortage, which negatively affected gross margin and could continue to do so.
Headcount grew to 21,921 at fiscal year-end from 16,068 at the prior year-end, including approximately 4,223 additional employees from the CyberArk acquisition. In connection with CyberArk integration, a workforce optimization plan was initiated with a total estimated cost of $60M; $18M in cash severance was paid during fiscal 2026, and $14M remained as a severance liability at July 31, 2026. The plan is expected to be substantially completed by the end of fiscal 2027.
In May 2026 (Q4), the company identified an authentication bypass vulnerability in certain versions of its PAN-OS software, published a security advisory, provided software updates, and engaged in customer outreach, support, and remediation efforts.

Completed acquisition of CyberArk on February 11, 2026, for $21.1 billion ($2.3B cash plus 112 million shares valued at $18.5B), forming the Idira next-generation identity security platform. Total headcount grew to 21,491 from 16,068 at the prior fiscal year-end, including approximately 4,166 from CyberArk. The company initiated a workforce optimization plan with an estimated $59 million total cost, expected to be substantially completed by the end of fiscal 2027; $12 million in cash severance was paid through April 30. Q3 results included $41 million in CyberArk transaction costs and $41 million in severance charges.
Completed acquisition of Koi Security on April 14, 2026, for $231 million to add agentic endpoint security capabilities to the Cortex security operations platform and enhance Prisma AIRS. Entered a definitive agreement on April 30, 2026, to acquire Portkey, an AI Gateway company, for $140 million in cash and replacement awards to further enhance Prisma AIRS; the transaction closed on May 29, 2026, as a subsequent event.

Next-Generation Security Annualized Recurring Revenue (NGS ARR) reached $8.1 billion as of April 30, 2026, up from $5.6 billion at the prior fiscal year-end; remaining performance obligations totaled $18.4 billion, of which approximately $8.3 billion is expected to be recognized as revenue over the next 12 months. Q3 revenue of $3.0 billion grew 31% year-over-year, reflecting contributions from the CyberArk and Chronosphere acquisitions in addition to organic demand.
In April 2026, entered three lease amendments extending the Santa Clara corporate headquarters lease terms by 12 years through July 2040 (with renewal options through July 2052), involving approximately $469 million in net lease payments over the extended term.

Q3 operating results reflected a net loss of $(177) million and an operating loss of $(183) million, compared to a net income of $262 million and operating income of $219 million in the prior-year quarter. The decline was driven by acquisition-related charges (CyberArk transaction costs, severance, and $177 million in accelerated equity vesting), higher intangible asset amortization, and personnel cost growth from acquisitions. Gross margin declined to 67.6% from 72.9% year-over-year.
