Cyber security services provider Palo Alto Networks (NYSE: PANW) continues to be on an acquisition spree this year. After it acquired CyberArk, its biggest acquisition earlier this year, it announced the acquisition of next-generation observability platform Chronosphere yesterday.

Palo Alto Network’s Financials

For the first quarter of the year, Palo Alto’s revenues grew 16% to $2.47 billion, ahead of the Street’s estimate of $2.46 billion. EPS of $0.93 was also ahead of the market’s forecast of $0.89 for the quarter.

By segment, Product revenues came in at $434 million compared with $354 million a year ago. Subscription and Support revenues grew to $2.04 billion from $1.79 billion a year ago.

For the second quarter, the company expects revenue of $2.57-$2.59 billion, compared with market estimates of $2.58 billion. Palo Alto Networks expects to end the year with revenues of $10.5-$10.54 billion, compared with market estimates of $10.51 billion.

Palo Alto Networks’ Chronosphere Acquisition

Yesterday, Palo Alto Networks announced plans to acquire next-gen observability leader Chronosphere for an estimated $3.35 billion. New York-based Chronosphere was founded in 2019 by Martin Mao and Rob Skillington who wanted to support companies using the open-source metrics engine M3, which they had helped develop at Uber.

The two realized that the observability challenges they faced at Uber were common in the market overall. With organizations relying on containerized environments, observability was becoming a problem. They wanted to build a commercial, cloud-native observability solution and created that in Chronosphere. Recently, Chronosphere was named a Leader in the 2025 Gartner Magic Quadrant for Observability Platforms.

Palo Alto wants to integrate Chronosphere’s observability architecture with its Cortex AgentiX platform. Chronosphere’s system has been built for massive data demands. It is already used in production by AI-native companies. By integrating the telemetry handled by Chronosphere with the autonomous AI agent capabilities of AgentiX, Palo Alto hopes to shift observability from a traditional monitoring model to a system capable of real-time autonomous remediation.

The joint solution will help AI agents detect performance issues, identify root causes, and automatically take corrective actions, thus providing organizations with deeper visibility across observability and security data.

Prior to the acquisition, Chronosphere was privately held. It had raised $55 million from investors including Greylock, Lux Capital, General Atlantic, Addition, and Founders Fund. The 60-member team reported annual recurring revenue of more than $160 million as of September 2025.

Palo Alto Networks’ stock is trading at $199.90 with a market capitalization of $136.7 billion. It was trading at a 52-week low of $144.15 in April this year, and had climbed to a 52-week high of $223.61 in October.
