Director Dana C. O'Brien sold 4,000 shares (4.0K shares) for $1,610,000.00 ($1.6M) across 3 separate transactions on Feb 6–9, 2026.

Director O'Brien executed 3 separate sales totaling 4,000 shares for $1,610,000.00 at prices ranging from $390.00 to $410.00 (blended average $402.50), reducing holdings by 25.8% from 15,498 to 11,498 shares. The stock currently trades at $415.19, near its 52-week high of $418.61 (-0.8%), and has rallied 34.8% over the past 30 days. His prior sell at STRL on 2025-06-16 was followed by positive 90-day returns (+51.8%), indicating his past STRL sales were poorly timed relative to subsequent price appreciation. The multi-tranche structure and timing during a strong price-momentum period warrant attention, though the absence of a 10b5-1 FLAG and favorable 30/90-day price action context make this a material but not critical signal.

Director O'Brien Dana C. sold 10,154 shares of STRL at $206.58 for $2,097,613.32, reducing holdings by 38.1%.

Director O'Brien Dana C. sold 10,154 shares at $206.58 on 2025-06-16, reducing her position from 26,652 shares to 16,498 shares—a 38.1% reduction in holdings. The stock is trading at $223.97, representing 20.4% appreciation over the past 30 days and 77.8% over 90 days, suggesting the sale occurred ahead of significant recent momentum. With Sterling Infrastructure trading at a P/E of 25.63, elevated relative to its 52-week trading range of $102.56–$223.97, the sale at $206.58 represents execution near year-to-date lows, prior to the sharp recent rally. The materiality of this transaction—both in dollar value ($2.1M) and proportional reduction of the director's stake—warrants investor attention, particularly given the timing relative to recent price acceleration and the company's elevated valuation multiples.
