Key Highlights

● A two-cent EPS miss triggered an outsized stock reaction.

● Fourth-quarter guidance and AI targets both disappointed.

● The Armis acquisition also weighed on the quarter.

● High-valuation software stocks are sensitive to any growth doubts.

ServiceNow missed earnings forecasts by just two cents a share, but a disappointing outlook and an underwhelming AI target turned that small shortfall into a steep slide in extended trading.

Two cents does not sound like much. For ServiceNow (NYSE:NOW) on Wednesday, October 28, it was the start of a very bad evening. The company reported adjusted third-quarter earnings of $1.00 a share, missing analysts' forecasts by two cents, according to one market recap. The shares then plunged in extended trading on the S&P 500, with reports differing on the size of the decline.

Small Miss, Big Reaction

On its own, a two-cent shortfall is the kind of result that might prompt a modest dip. What turned it into a steep slide was the rest of the report. ServiceNow's fourth-quarter guidance and its AI target underwhelmed investors, according to market reports, and its acquisition of cybersecurity company Armis weighed on results.

Together, those factors suggested that growth may not be accelerating as fast as investors had expected. For a high-valuation software company, the outlook usually matters far more than a single quarter's earnings, since investors pay a premium for confidence in future growth.

The AI Premium at Risk

ServiceNow has been one of the most prominent software companies pitching itself as an AI winner. Its platform helps large organizations automate IT, customer service and HR workflows, and it has been adding AI agents and charging for premium AI capabilities.

That narrative has supported the stock's valuation, which means the company's AI targets are watched especially closely. An AI target that failed to impress cut straight to the core of the investment case, and investors appeared to focus on that rather than the small earnings miss.

A Night of Divergence

ServiceNow's slide was part of a volatile after-hours session for technology stocks. Fortinet (NASDAQ:FTNT) also plunged in extended trading, with sources differing on whether its results were weak or solid. Alphabet (NASDAQ:GOOGL) slid sharply after missing earnings forecasts and reporting negative free cash flow, while Microsoft (NASDAQ:MSFT) climbed after beating on revenue and posting faster Azure growth.

The pattern showed investors rewarding clear evidence of AI-driven growth and punishing anything that fell short. Earlier in the day, the S&P 500 rose 21.38 points to 7,743.98, its third straight gain, while the Dow Jones Industrial Average added 97.53 points to 52,475.10.

What to Watch

Thursday's open will show whether ServiceNow's after-hours losses deepen or ease, and whether the selling spreads to other enterprise software names.

Analysts' reactions to the guidance and AI target will be closely watched, as will any further detail on the Armis integration. The advance estimate of third-quarter GDP and September PCE inflation arrive at 8:30 a.m. ET Thursday, and Amazon (NASDAQ:AMZN) reports after the close.
