Software stocks slide as Fortinet, ServiceNow fail to meet lofty investor expectations

By Thomson Reuters Oct 29, 2026 | 5:19 AM

Oct 29 (Reuters) – Shares of software companies tumbled in premarket trading on Thursday following disappointing results from Fortinet and ServiceNow, deepening worries about AI disruption ​that has plagued the sector.

Software companies have been ‌under intense scrutiny this year as investors weigh the likelihood of newer AI models disrupting traditional business models.

The S&P 500 Software & Services Index has managed a 6% year-to-date rise, just about half the ‌gains ​recorded by the S&P 500.

Fortinet was ⁠down 25% and was ⁠the top decliner on Wall Street’s benchmark index.

The company outperformed during the third quarter and raised its earnings and revenue expectations. However, investors wanted more from the ​company, whose stock has rallied 119% this year.

At least five brokerages cut their price targets on the stock, ⁠including Piper Sandler, Jefferies and ⁠RBC.

“We remain on the sidelines as we ​await evidence that new areas such as protecting east-west traffic from ​agentic adoption, large firewall AI data center-related deals, ‌and (operation technology), can truly continue firewall momentum,” said Scotiabank, which cut its price target on Fortinet to $140 from $163.

“Similarly, we would like to see Fortinet’s SASE and SecOps offerings ⁠demonstrate greater enterprise traction in upcoming results.”

ServiceNow slid 18.1% as a third-quarter profit miss overshadowed a raise to its full-year subscription ⁠revenue and cash ‌flow margin outlook.

The companies’ results weighed on ⁠other software stocks. Salesforce fell 4.3%, Palo ​Alto ‌Networks slid 6%, CrowdStrike dropped 5% and ​Zscaler shed ⁠5.8%.

Alphabet’s Google on Wednesday unveiled Gemini 4 Carbon, its latest frontier AI model, stepping up competition with OpenAI and Anthropic as the race to build more capable coding and cybersecurity systems intensifies.
