On December 11, 2025, SentinelOne President and CEO Tomer Weingarten sold 125,429 shares through an open-market transaction, generating approximately $1.9 million in proceeds. According to the company’s SEC Form 4 filing, this sale reduced his direct holdings from 1,218,537 to 1,093,108 shares, representing a 10.29% decline in his personally held stake. The transaction value and post-transaction stake valuation are based on a weighted average exercise price of $15.09 per share, leaving his direct position valued at roughly $16.5 million following the sale.

On January 12, 2026, Citigroup revised its recommendation on SentinelOne stock from Buy to Neutral, citing slower-than-expected revenue growth trends and intensifying competition in the cybersecurity sector. At the time of the update, the firm also reduced its 12-month price target by 10% to $18. Analysts noted that SentinelOne’s trailing-twelve-month revenue of $955.7 million, while up year-over-year, fell short of the high-growth benchmarks set by peer companies. Citigroup’s downgrade reflects concerns over margin pressure—gross margin stood at 74.5%—and the potential impact of the CFO transition scheduled for mid-January.

SentinelOne Chief Financial Officer Barbara Larson reported the sale of 11,173 shares in a Form 4 filing covering a recent transaction executed at an average price of $14.82. The disposal reduced her direct ownership by 2.03%, leaving her with 539,372 shares valued at approximately $8 million. The sale was executed under a pre-arranged trading plan, and disclosures indicate it was completed to satisfy personal liquidity requirements rather than signal a shift in her long-term view of the business.
