Cybersecurity firm SentinelOne, Inc. (S) experienced a sharp pre-market plunge of 17.31% following the release of its fiscal first-quarter financial results and a company restructuring announcement.

The company reported Q1 revenue of $277 million, which slightly missed the consensus estimate. More concerning to investors was the company's Q2 revenue guidance of $289-291 million, which fell short of analyst expectations. Additionally, SentinelOne announced a restructuring plan to focus on AI, data, cloud, and endpoint security, which includes reducing its full-time workforce by approximately 8%. The company expects to incur a one-time charge of about $25 million related to the restructuring.

The negative sentiment was further amplified by analyst downgrades, with D.A. Davidson cutting its price target and Raymond James moving to a market perform rating. This combination of a revenue miss, tepid forward guidance, significant organizational changes, and analyst downgrades drove the sharp sell-off in pre-market trading.
