AI Cybersecurity Stocks Plunge 16% Ahead of Earnings: What Happened?

AI-driven cybersecurity stock SentinelOne Inc. (NYSE: S) plunged more than 16% on the New York Stock Exchange, closing at $14.99. In a single session, roughly $700 million—nearly KRW 1 trillion—in market capitalization was wiped out, and trading volume surged to about 11.63 million shares, well above its average.

SentinelOne is slated to report first-quarter earnings after today’s U.S. market close, and investor caution over short-term earnings risk is seen as having fueled the steep decline. On the other hand, Barclays raised its price target for the company from $16 to $19 last week, reflecting continued confidence on Wall Street in its medium- to long-term growth prospects.

SentinelOne provides its AI-powered autonomous threat detection and response platform, Singularity, to U.S. and global enterprises. Its key strength lies in delivering unified endpoint, cloud, and identity security. Since its NYSE debut in 2021, the company has grown revenue to $1 billion (approximately KRW 1.3 trillion). In 2025, it bolstered its AI security capabilities by acquiring generative AI security startup Prompt Security for about $250 million (around KRW 300 billion). (trendmatrix.com)
