10% owner William H Gates III sold 276,542 shares for $67.2M across Nov 20–22, reducing stake to 29.18M shares.
William H Gates III, a 10% owner of Ecolab Inc., conducted 9 separate sales totaling 276,542 shares for $67,194,910.13 across three trading days (November 20–22, 2024) at prices ranging from $240.66 to $246.85, with a blended average price of $242.98. This reduced his holdings from 29,455,283 shares to 29,178,741 shares, representing a -0.9% reduction in his stake. The current stock price of $245.30 is -6.2% from the 52-week high and down -5.2% over the past 30 days, suggesting the sales occurred near recent price strength. His cross-ticker track record shows 20 prior open-market sells, though none of his prior 5 trades at Ecolab have yet reached the 90-day measurement window. The sale of a material stake ($67.2M) by a principal shareholder warrants scrutiny regarding his forward outlook on the company, particularly given Ecolab's elevated P/E of 33.98 relative to recent price momentum.
