ServiceNow Stock Falls 27% to $109.67, Worst Day in Company History, After Weak Bookings Guidance

Since Alphabet's $500 billion market-value loss earlier on Thursday, Oct. 29, Wall Street's AI anxiety has found a second target: ServiceNow.

The enterprise software company's stock closed at $109.67, down $40.46, or 26.95%, according to Yahoo Finance data. That is the worst day in the company's history. The previous record was a 17.7% slide on April 23, according to TradingView. Both of ServiceNow's two worst sessions as a public company have now come in 2026, and both followed quarters in which it beat its own guidance.

After hours, the stock was at $108.02 as of 6:45 PM ET, down another 1.5%.

What ServiceNow reported

The company reported third-quarter results Wednesday, Oct. 28. Revenue rose 20.5% to $4.11 billion, slightly ahead of the roughly $4.09 billion analysts expected. Adjusted earnings came in at $1.00 a share against a $1.02 consensus.

The shortfall traces to the balance sheet. ServiceNow spent about $9.2 billion on acquisitions in the first nine months of 2026, including the cybersecurity company Armis, and borrowed to pay for them. Quarterly interest expense jumped to $81 million from $6 million a year earlier. Interest income fell to $69 million from $115 million as cash balances shrank, according to the company's results.

CFO Gina Mastantuono attributed the miss to lower interest income and added debt costs from the Armis deal. CEO Bill McDermott made the same argument and said operating margin still widened 150 basis points.

The stock had already fallen about 18% in after-hours trading Wednesday night.

The number that moved the stock

The bigger problem was forward guidance. ServiceNow guided fourth-quarter current remaining performance obligations, or cRPO, to growth of 18.5%. That is contracted revenue the company expects to recognize over the next 12 months, and investors treat it as the cleanest read on future sales. Analyst expectations ran between roughly 19% and 20%, depending on the source. Third-quarter cRPO grew about 21% to $13.65 billion.

Fourth-quarter subscription revenue guidance of $4.245 billion to $4.255 billion roughly matched Wall Street's numbers. The company slightly raised full-year 2026 subscription revenue guidance to $15.78 billion to $15.79 billion.

Citi analyst Tyler Radke told CNBC the quarter was "a little bit uncharacteristic for ServiceNow standards, just in terms of the lack of upside." He pointed to the company's new forward-deployed engineering team, which embeds with customers to build AI systems. "I think you got to wait until next year to really see that inflection," Radke said.

The AI numbers are real, and so is the fear

The AI business is growing. ServiceNow raised its 2026 AI annual contract value target to $1.7 billion, up from $1.5 billion set in May and $1 billion at the start of the year. Net new AI average contract value jumped 65%. Deals worth more than $5 million in net new annual contract value rose 135%. McDermott said AI consumption in production is up more than 13-fold from a year ago and called the quarter "the inflection point for ServiceNow."

The market is not asking whether AI sells. It is asking whether AI agents will erode the per-seat software model that built companies like ServiceNow. A slowdown in forward bookings feeds that argument even when the AI line grows.

Mastantuono pushed back on how investors read the metric. "CRPO, while it's a good metric that talks about what next year's revenue will look like, it's not perfect," she told Yahoo Finance. "It's a nuanced accounting metric that doesn't necessarily capture all of the momentum in the business."

Oppenheimer's Brian Schwartz, who rates the stock Buy with a $165 target, wrote that ServiceNow's adoption numbers show the company is not being disrupted by AI. He added the results do not "establish a clear path to organic reacceleration." Morgan Stanley kept an Overweight rating but cut its target to $160 from $180, citing decelerating cRPO and the cost of the forward-deployed engineers.

Software sector takes the hit

The damage spread. The iShares Expanded Tech-Software ETF fell 3.3%. Salesforce dropped 4.6% and Workday lost 4%.

Fortinet fell about 20% after cutting its full-year service revenue forecast to $5.15 billion to $5.17 billion from $5.18 billion to $5.22 billion, below the $5.2 billion analysts expected, according to Bloomberg data. BofA cut Fortinet to Neutral with a $140 target. Mizuho lowered its target to $118 from $160. CrowdStrike, Okta and Palo Alto Networks also declined but pared losses during the session.

The moves came on a day when Alphabet shares fell 12.6%, the stock's worst day ever, after its search advertising results came in below expectations. After the close, Amazon reported third-quarter revenue short of Wall Street's expectations, and its shares slid about 10% in after-hours trading, NBC News reported.

What comes next

Share prices measure what buyers will pay, not what any particular investor lost. The arithmetic of the day is clear: ServiceNow's stock closed at $158.96 on Oct. 23 and sits near $110 tonight, about 27% below that October peak.

The test arrives with fourth-quarter results. ServiceNow has guided to 18.5% cRPO growth, and Radke's view is that the payoff from its engineering push will not show until next year. Until then, the stock is trading on whether AI contracts grow fast enough to outrun the fear that AI shrinks the software market.
