ServiceNow (NOW) shares collapsed 27 percent to $110 on its worst trading day since going public after the enterprise software provider cut guidance on a critical metric: current Remaining Performance Obligations (cRPO) growth.

The company reported revenue that beat Wall Street expectations. But investors immediately repriced the stock on the downward revision to cRPO growth—now projected at 18.5 percent versus prior guidance of 21 percent. For a subscription-software business, that 250-basis-point miss on recurring-revenue expansion forces a fundamental revaluation.

Options markets confirmed institutional positioning for additional downside. Net call premium swung to negative $300 million—heavy selling of bullish bets. Put premium surged $128 million positive, reflecting aggressive hedging or new short positioning. That options flow is the footprint of serious money rotating away.

Why this matters for your models: ServiceNow's valuation multiple has always hinged on its ability to deliver mid-20s percent recurring-revenue growth. A drop to 18.5 percent—and the possibility of further deceleration—forces a multiple compression that extends beyond NOW to the entire high-growth SaaS cohort. Peers trading at elevated multiples on similar growth assumptions face similar execution risk. Watch Q1 bookings closely; if cRPO guidance compresses again, the 27 percent drop will look like a warmup.
