Key Highlights

  • ServiceNow (NYSE:NOW) fell 26.5 percent on October 29, 2026, closing at USD 110.30, the biggest one-day decline among S&P 500 members that day, according to two recaps.
  • Adjusted EPS of USD 0.27 missed expectations. One recap cites about USD 0.35 expected and another a miss of USD 0.02, so the size of the shortfall is disputed.
  • The 2026 subscription Revenue guide from ServiceNow (NYSE:NOW) sits at about USD 15.78 billion to 15.79 billion, while weak Q4 guidance was reported by one recap only.
  • The after-hours drop recorded on October 28, 2026 was 14 percent to 19 percent, so the regular session loss extended an already steep fall in the stock.

A Record Drop in the S&P 500

ServiceNow (NYSE:NOW) fell 26.5 percent on October 29, 2026 to close at USD 110.30, its largest one-day fall as a member of the S&P 500, according to two recaps. The decline followed results reported on October 28, after which the shares had already dropped between 14 percent and 19 percent after hours. Adjusted Earnings Per Share were USD 0.27. One recap cites an expected USD 0.35, while another describes a miss of only USD 0.02, so the true gap is unresolved. The company guided 2026 subscription revenue to about USD 15.78 billion to 15.79 billion, and one recap said Q4 guidance was weak. That cause is single-source and has not been checked against a filing.

Why Software Multiples Compress

Subscription software is valued on forward growth. When a leader like ServiceNow (NYSE:NOW) hints that near-term growth may slow, investors cut the multiple they pay for each dollar of future revenue, so a modest estimate cut can become a large price move. A miss at a bellwether also raises doubt about peers that sell similar workflow and AI tools. The ripple reached Fortinet, which fell about 21 percent the same day, and the software ETF slid about 4 percent according to one recap. Fears that AI is compressing enterprise software budgets sit behind the sector move, and ServiceNow is the largest test case of that thesis so far.

Risks and What to Watch

The main risk for ServiceNow (NYSE:NOW) is that customers hold back new contracts while they weigh AI spending against existing platforms, which would slow subscription growth beyond the current guide. A second risk is that sentiment stays negative until a clearer Q4 picture emerges. Because EPS expectations and the Q4 commentary conflict across recaps, readers should rely on the company release for final numbers. The S&P 500 fell 0.30 percent on October 29, and Nasdaq-100 futures were about 2.5 percent lower on Friday morning, so the sector is not trading in isolation. Watch the 9:30 a.m. ET open and any analyst notes on the 2026 subscription revenue guide.

Where Things Stand

ServiceNow (NYSE:NOW) crashed 26.5 percent because a modest earnings miss and a cautious outlook hit a stock priced for steady growth. The close at USD 110.30 followed a 14 percent to 19 percent after-hours drop, and the sell-off spread to Fortinet and the software ETF. The evidence is incomplete: the EPS gap is disputed, and the Q4 weakness is reported by one recap. Even so, the market message is that growth expectations were too high. The next catalyst is the regular session open and whether analysts reset estimates after the 2026 subscription revenue guide of about USD 15.78 billion to 15.79 billion.
