ServiceTitan stock was falling sharply in after-hours trading despite beating expectations for second quarter earnings. It’s likely investors were disappointed by a third quarter revenue outlook that fell short of Wall Street’s estimates.

The stock was down more than 20% after hours.

The maker of software used by home service and commercial contractors and other trades reported second quarter earnings of 40 cents a share and revenue of $292.8 million, a gain of nearly 21% from a year ago. Analysts had expected profit of 35 cents a share and revenue of $285.9 million.

For the third quarter, ServiceTitan sees revenue in a range of $285 million to $287 million, though analysts are tracking $288 million, according to FactSet.

Co-founder and CEO Ara Mahdessian said their agentic operating system added $50 million of non-GAAP free cash flow in the second quarter, adding that delivering this system and leveraging AI are “once in a lifetime opportunities.”

Gross transaction volume in the second quarter rose 19% to $22.9 billion. That’s the sum of money invoiced by ServiceTitan’s customers through the platform, which it says is a proxy for the total revenue its customers generate.

Full-year revenue guidance of $1.139 billion to $1.144 billion is running slightly ahead of the $1.138 billion expected by analysts.
