Why SentinelOne (S) Is Down 11.5% After AI-Focused AWS Deal And Cost-Cutting Restructuring Plan

May 31, 2026 - 11:49

SentinelOne saw its stock drop more than 11 percent in late May after the cybersecurity company reported mixed quarterly results and announced a restructuring plan that includes cutting 8 percent of its workforce. The decline came even as the firm highlighted a major new partnership with Amazon Web Services aimed at expanding its artificial intelligence capabilities.

For the first quarter of fiscal 2027, which ended in April 2026, SentinelOne posted revenue of $276.66 million. That figure came in above analyst expectations, but the company's net loss, while narrowed to $76.16 million from a year earlier, still weighed on investor sentiment. SentinelOne also issued updated guidance for the second quarter and the full year, though the outlook did not appear to reassure the market.

The restructuring plan involves laying off roughly 8 percent of employees as part of a broader cost-cutting effort. The company said the move is designed to streamline operations and improve profitability as it continues to invest in growth areas.

On the positive side, SentinelOne deepened its integration with AWS, making its Singularity Platform available directly through the AWS Security Hub Extended marketplace. The deal allows customers to access the platform on a pay-as-you-go basis, which could lower the barrier for smaller businesses to adopt advanced AI-driven threat detection. The partnership is part of a broader push by SentinelOne to embed its technology deeper into the cloud ecosystems of major providers.

Analysts noted that while the AWS deal is strategically sound, the near-term financial picture remains uncertain. The stock's sharp drop suggests that investors are focused on the restructuring and the path to consistent profitability rather than the long-term potential of the AI partnership.
