Shares in Palo Alto Networks Inc. declined more than 2% in late trading today after the company reported earnings and revenue beats in its fiscal 2026 first quarter and announced that it will acquire cloud-native observability company Chronosphere Inc.

For the quarter that ended on Oct. 31, Palo Alto Networks reported adjusted earnings per share of 93 cents, up from 78 cents per share in the same quarter of the previous fiscal year, on revenue of $2.47 billion, up 16% year-over-year. Both figures were ahead of the 89 cents per share and revenue of $2.46 billion expected by analysts.

For its 2026 fiscal second quarter, Palo Alto Networks expects adjusted earnings per share of 93 to 95 cents on revenue of $2.57 billion to $2.59 billion. At the midpoint, the outlook was ahead of the 93 cents per share expected by analysts but fell short of an expected $2.59 billion in revenue.

“Our strong start to the fiscal year was marked by excellent results across all metrics and significant platformization wins,” Nikesh Arora, chairman and chief executive officer of Palo Alto Networks, said in the company’s earnings release. “Our robust innovation engine, paired with the strategic acquisitions of CyberArk and Chronosphere, positions us as the data and security partner of choice in the AI era.”

Indeed, the acquisition overshadowed the earnings. The deal, if approved by Chronosphere shareholders, will see Palo Alto Networks pay $3.35 billion in cash and replacement equity awards, subject to adjustments.

Founded in 2019, Chronosphere offers a cloud-native observability platform designed for modern, distributed infrastructure. The platform ingests vast quantities of metrics, traces and logs and allows engineering and DevOps teams to monitor, analyze and troubleshoot their applications and infrastructure in real time.

Chronosphere’s platform emphasizes control, cost-efficiency and scale and helps organizations reduce non-actionable data, prioritize relevant signals and avoid being overwhelmed by telemetry noise.

The company serves clients who operate at cloud scale, such as organizations with thousands of microservices, large fleets of containers and high-volume telemetry workloads. Its services shorten the time to detect and resolve incidents, lowering the total cost of observability by reducing redundant data and facilitating faster feedback loops for engineering teams.

Coming into its acquisition, Chronosphere had raised $369 million in funding across four rounds, including a round of $43.3 million in January 2021, $200 million in October 2021 and $115 million in January 2023.

“We founded Chronosphere to provide scalable resiliency for the world’s largest digital organizations,” said co-founder and CEO Martin Mao. “Palo Alto Networks is the perfect strategic partner for our customers, partners and employees. It allows us to combine our disruptive observability platform with the world’s best security company, accelerating our momentum in solving the most complex data and resiliency challenges.”

Mao spoke with theCUBE, SiliconANGLE Media’s livestream studio, back in June, when he discussed how Chronosphere was redefining cloud-native observability with Logs 2.0 and real-time data control:
