Co-CEO Thurmond sold 28,500 TENB shares at $30.25; stock down -33.6% from 52-week high, all 4 prior same-ticker sales were 90d well-timed.
Thurmond Mark C. sold 28,500 shares (28.5K shares) at $30.25 on 2025-08-25, reducing his holdings by -20.9% from 136,042 to 107,542 shares. This sale occurs as TENB trades at $29.56, down -33.6% from its 52-week high of $44.50 and down -11.0% over the past 30 days. Critically, Thurmond's entire same-ticker history at TENB shows 4 of 4 prior sales were well-timed at the 90-day mark (2024-03-20: 90d -20.1%, 2024-02-07: 90d -11.3%, 2023-08-24: 90d -9.0%, 2023-08-22: 90d -12.5%), demonstrating a consistent pattern of selling ahead of subsequent declines. The company posted $247,295,000.00 in latest-quarter revenue with -$14,706,000.00 net income and remains unprofitable on a full-year basis, adding fundamental uncertainty to the stock's position. The insider's perfect 90-day timing record at this ticker—when combined with the stock's sharp downward trajectory and negative earnings backdrop—suggests this sale warrants monitoring for potential signals about near-term price movement.
