After-hours: ServiceNow plunges 12% after Q1 as company trims margin guidance

What happened (after-hours)

ServiceNow (ticker: NOW) slid roughly 12.39% in after-hours trading on April 22, 2026, with after-hours volume running at about 31.9 million shares — an outsized move compared with a flat S&P 500 (SPY) in the same period. This was an after-the-close reaction to the company’s Q1 results and management commentary released after market close.

The catalyst: margins and acquisitions

Investors punished the stock after management trimmed operating-margin expectations. ServiceNow cut its full-year adjusted operating margin target to 31.5% from a prior 32.0% and forecast a Q2 adjusted operating margin of 26.5%, well below the roughly 30.1% Wall Street consensus. Analysts and market commentators flagged the driver as integration costs from recent deals — notably the Armis acquisition — that will create near-term margin headwinds.

At the same time, ServiceNow highlighted positive underlying metrics: subscription revenue of $3.67 billion in Q1 (about +22% year-over-year), adjusted EPS of $0.97, remaining performance obligations (RPO) of $27.7 billion, and an increased 2026 AI revenue target of $1.5 billion (up from $1.0 billion). Management also completed roughly $2 billion of share repurchases in Q1.

Why the market cares

The market’s reaction shows investors are weighing near-term profit dilution from acquisitions and integration against longer-term AI-driven revenue gains. The company itself quantified the headwind tied to the Armis deal — management signaled the acquisition will shave roughly 75 basis points off full-year operating margin and about 125 basis points in Q2, with additional pressure on subscription gross margin and free cash flow for 2026.

Those explicit margin hits appear to have overwhelmed better-than-expected top-line and AI commentary in traders’ calculus, producing the sharp after-hours drop. Benchmark and other analysts noted the margin miss was the central story, suggesting integration and restructuring costs are being priced in now rather than later.

Sector and peer context

The move is not isolated to NOW: software and enterprise-application names have been volatile this year as investors re-price the trade-off between AI investment and near-term profitability. Market participants noted similar weakness in some software peers in extended trading, signaling a risk-off shift in the group after earnings season updates.

What to watch next

- Management’s conference call commentary and Q&A later this evening and the company’s prepared slides for more color on the magnitude and timeline of Armis integration costs.

- Analyst reactions and any updates to price targets or ratings that could follow the margin revision.

- Whether the stock’s after-hours drop extends into Thursday’s regular session — a continued selloff would test key technical support and could draw bargain hunters if fundamentals remain intact.

Forward-looking perspective: ServiceNow’s core subscription growth and a raised AI revenue target argue the company’s long-term growth thesis remains intact, but the market is punishing near-term margin dilution. For investors, the trade now is between patience for integration-driven pain and conviction in the company’s AI-driven revenue acceleration; the next 48–72 hours — management’s Q&A and analyst reactions — will determine whether this after-hours plunge is a buying opportunity or the start of deeper repricing.
