Why is ServiceTitan stock plunging over 17% today?

ServiceTitan's stock experienced a significant decline of over 17% in pre-open trading today, reaching a price of $67.49, following the release of its fiscal second-quarter 2027 earnings report on September 8. Despite revenue exceeding expectations at $292.8 million, which represented a 21% year-over-year growth, investors quickly turned their attention to other issues.

Weak forward guidance and a notable change in leadership were the primary concerns. Gross Transaction Volume slowed down to $26.8 billion, slightly below its normalized pace, and Q3 revenue guidance suggested a decline from Q2 and moderate growth for the remainder of the fiscal year. The company also announced that its Chief Revenue Officer, Ross Biestman, would be stepping down, with SVP of Worldwide Sales, Rikus Pretorius, taking over the role beginning in Q4.

Analysts reacted promptly, with Canaccord lowering its price target to $90 from $105 while maintaining a Buy rating, and Wells Fargo reducing its target from $115 to $105, keeping an Overweight rating. Needham, however, maintained a positive outlook with a Buy rating and $100 price target, recognizing the company's strategic shift towards AI with its Max product.

Despite the revenue beat, broader market conditions, and the combination of a cautious near-term outlook, decelerating transaction volume, margin concerns in Q3 guidance, and the senior leadership transition proved to be too much for investors to handle, resulting in one of the stock's most substantial single-session declines and pushing shares towards the lower end of its 52-week range of $54.17 to $119.60.
