Why is SentinelOne, Inc. (S) stock moving?
Shares closed at $23.43 on Nov 10, below the $25.71 close on Oct 29 and above the $21.31 intraday low hit on Nov 5. That low came on 10.1M shares and 91K trades, with the stock closing at $21.42 that day. The stock rebounded to $23.52 on Nov 9 on 7.7M shares, and Nov 10 held near that level on 10.4M shares. The recent news is product and partnership news: Anthropic integrations on Oct 29 and Nov 2, a Snyk integration on Nov 4, and a Cloudflare partner award on Nov 5. None of these items gives financial figures. The Oct 16 filing proposed $1.25B of 0% convertible notes due 2031 with up to $187.5M more, alongside up to $150.0M of concurrent buybacks and capped calls meant to limit dilution. The final pricing terms are not in the supplied news, so the net dilution effect is unclear. The provided news does not explain the Nov 5 selloff.

About SentinelOne, Inc.
SentinelOne is a US cybersecurity company that sells its AI-driven Singularity platform, which protects laptops, servers, cloud workloads and user identities from attacks. It's known for automated, AI-based detection and response that needs less hands-on work from security staff, and it's smaller than its main rivals: annual revenue first passed roughly $1 billion in fiscal 2026 (the year ending January 2026), and the company still reports net losses on a standard accounting basis.
How it makes money
Nearly all of its revenue comes from subscriptions, mostly priced per protected device or workload. The core product is endpoint protection (often called EDR/XDR). It also sells add-ons such as cloud security, identity protection, data and logging (SIEM-style) analytics, AI security tools and managed threat-hunting services. Customers buy directly or through resellers, managed security providers and partners. Recurring subscriptions make up the large majority of revenue.
What usually moves S
- Growth in annual recurring revenue and customer spending
- Competition with CrowdStrike and Microsoft
- Progress toward profitability and margins
- Corporate IT and cybersecurity budgets
