Mark S. Schroeder (EVP, Pres Diagnostics & COO) sold 2,635 shares of LH at $231.67; stock down 7.3% in 30 days post-sale.
Schroeder sold 2,635 shares (34.7% of his pre-transaction holding of 7,595 shares) at $231.67 on 2025-03-28, reducing his position from 7.6K to 5.0K shares. The stock has declined 7.3% over the subsequent 30 days and trades 9.4% below its 52-week high of $256.81. His same-ticker trade history at LH shows 3 prior measurable 90-day outcomes, all negative: −13.8%, −9.4%, and −6.3%, consistent with a pattern of well-timed exit execution. His cross-ticker track record shows 4 prior sells with an average 90-day return of −8.1% and a 100.00% well-timed rate, indicating his open-market sales have historically preceded declines. The company's fundamentals remain solid (7.0% annual revenue growth, P/E 25.52, $3.3B quarterly revenue), but the consistent post-sale price weakness in this insider's history warrants attention as a potential technical or fundamental headwind signal.
