Key Highlights

● ServiceNow shares fell to $109.67 from $150.13, the worst day on record.

● Adjusted Earnings of $1.00 a share missed the $1.02 consensus by two cents.

● Fourth-quarter cRPO growth guidance came in below analyst expectations.

● Revenue of $4.11 billion beat, and the full-year subscription outlook was raised.

ServiceNow (NYSE:NOW) missed profit estimates by two cents and guided a key growth metric below forecasts, and investors responded with the worst day in the software maker's history on Thursday.

Two cents and a guidance gap

For six straight quarters, ServiceNow had topped analysts' earnings forecasts. On Wednesday evening, the streak ended. The enterprise software company reported third-quarter adjusted earnings of $1.00 a share, two cents short of the $1.02 consensus, according to market data.

On its own, that miss would hardly justify a collapse. But on Thursday, October 29, ServiceNow shares plunged to $109.67 from a prior close of $150.13, its worst day on record. Prices reflect the company's recent five-for-one stock split. Figures for the size of the drop varied slightly by source, but all described a historic rout.

The number that mattered most

Revenue was actually fine. ServiceNow brought in $4.11 billion, a touch above the $4.09 billion estimate, and subscription Revenue reached $3.99 billion. The company even raised its full-year subscription revenue outlook to $15.78 billion to $15.79 billion.

The problem was current remaining performance obligations, or cRPO. This metric measures contracted revenue the company expects to recognize over the next 12 months, and investors treat it as one of the best guides to future growth for subscription software. ServiceNow guided fourth-quarter cRPO growth below what analysts had expected, and below the pace it reported in the third quarter, according to market data. Sources differed slightly on what the consensus had been, but agreed the guide fell short.

A slowing cRPO signals that new and renewed contracts are not growing as quickly as before. For a stock priced on the assumption of steady acceleration, that was enough to reset the valuation.

Why the reaction was so extreme

Streaks build expectations. When a company beats for six quarters in a row, investors start to price in the next beat. A miss, even a small one, removes that cushion.

The timing was also unfortunate. ServiceNow reported alongside Alphabet (NASDAQ:GOOGL), whose results revived concerns about mounting AI costs, according to media reports. Software stocks have faced worries that AI could change how businesses buy enterprise tools, and a weaker growth signal from one of the sector's leaders amplified those fears.

Fortinet (NASDAQ:FTNT), which also reported Wednesday, collapsed after cutting its service revenue forecast. Together, the two drove a broad software selloff. The iShares Expanded Tech-Software ETF, IGV, slid hard, and Salesforce (NYSE:CRM), Palo Alto Networks (NASDAQ:PANW) and CrowdStrike (NASDAQ:CRWD) all fell.

Not everyone turned bearish

Some analysts stayed with the stock. One brokerage reaffirmed its Overweight rating with a $175 price target, according to market data. That target sits well above Thursday's close, showing how far opinions diverged after the report.

The selloff contributed to a lopsided market. The Nasdaq Composite dropped 365.13 points to 26,184.72, while the Russell 2000 climbed 28.71 points to 2,859.22 as investors favored smaller, less AI-exposed companies.

A lesson in beat streaks

ServiceNow's plunge is a reminder that the market grades growth companies on the future, not the past. A record of beats earns a premium, but that premium can vanish quickly when guidance disappoints. The bigger the premium, the less room there is for even a modest disappointment.

What to watch

Investors will watch whether ServiceNow stabilizes after its reset, or whether other software companies reporting in coming weeks face the same scrutiny of forward-looking metrics like cRPO. Any analyst downgrades or target cuts could add pressure, while signs of steadier contract growth from peers might help the sector recover.
