Shares of ServiceNow cratered 24.9% to MXN 2,175.99 after the enterprise software giant's third-quarter results and fourth-quarter outlook fell short of Wall Street's expectations — its sharpest single-day decline in years and a warning sign for investors who had priced the stock for near-flawless execution. ServiceNow Suffers Worst Day Since IPO as Slowing Bookings Raise a Pivotal Question: Can AI Sell Enough to Replace Old-Fashioned Contract Growth?

Shares of ServiceNow plummeted as much as 27% — the worst single-day drop since the company went public in 2012 — after third-quarter results that beat on revenue but missed on earnings and, more critically, signaled a deceleration in the pace of new business coming through the door. All year, the stock has been weighed down by fears that AI agents will shrink demand for software sold by the seat , and the guidance confirmed those anxieties aren't going away.

• A Penny Miss Hides a Bigger Problem in the Forecast. Revenue grew more than 20% to $4.11 billion, roughly in line with estimates, but adjusted earnings came in at $1.00 per share versus a $1.02 forecast. On its own, the two-cent miss is trivial. What spooked investors was the outlook: ServiceNow's current backlog — the contracted revenue it expects to record over the next twelve months — grew 21% in Q3, but management guided that down to 18.5% for Q4.

Reported cRPO growth has now gone 22.5%, 21%, and 20.5% in the first three quarters of 2026 — a clear downward trend that makes the Q4 step-down feel structural rather than seasonal.

• A Sky-High Valuation Left Zero Room for Disappointment. ServiceNow trades at a trailing price-to-earnings ratio of 79, at the high end of its peer range alongside Salesforce at 21 and Workday at 40 . At that premium, investors demand consistent acceleration, not deceleration. Citi's Tyler Radke called the quarter "a little bit uncharacteristic for ServiceNow standards, just in terms of the lack of upside."

• AI Revenue Is Booming — But Not Fast Enough to Change the Narrative. ServiceNow raised its AI annual contract value target to $1.7 billion from $1.5 billion , and the number of AI deals over $1 million grew 4.5x year-over-year in Q3. Yet the market's fear is that AI tools could replace workflows that customers currently pay ServiceNow for, cannibalizing traditional subscription seats even as new AI products ramp. This week's slowing backlog outlook shifts the focus from ServiceNow's AI momentum to whether enterprise workflow platforms face long-term growth friction.

• History Favors Patience, But the Stakes Are Different Now. Before this drop, ServiceNow had lost more than 10% in a single session ten times since its IPO; in seven of those ten cases, the stock was higher six months later.

After this selloff, ServiceNow trades at roughly 23 times expected 2027 earnings — cheaper, but still demanding sustained high-teens growth in a market that just watched its bookings trajectory bend lower.
