ECL ECOLAB INC. Insider Trading

Maclennan (Director) buys 1,000 ECL shares at $250.65; stock down 19.5% from 52-week high and 8.9% in 30 days.

Director David Maclennan purchased 1,000 shares of ECOLAB INC. at $250.65 on 2026-05-13, increasing his holdings to 25,230 shares, at a time when the stock has declined 19.5% from its 52-week high of $309.27 and fallen 8.9% over the past 30 days. Maclennan's prior buy activity shows 15 historical purchases with an average 90-day return of +6.3% and a 66.67% win rate across all holdings, though this aggregate track record does not specify timing outcomes specific to ECL. The company trades at a P/E of 33.27 with $4.1B in latest quarterly revenue and $432.6M in net income, suggesting a premium valuation despite modest annual revenue growth of 2.2%. The purchase occurs against a backdrop of significant recent price weakness, warranting monitoring of whether this signals insider confidence or market-driven acquisition rhythm.

Director David MacLennan purchases 800 Ecolab shares as stock trades below 52-week high; mixed prior timing, profitable fundamentals.

Director David MacLennan bought 800 shares of Ecolab at market prices, adding modestly to his existing stake in a company that remains profitable and revenue-positive despite the stock trading well below its 52-week high. His prior open-market activity at Ecolab shows mixed results—three of his five previous purchases in this stock were well-timed (stock moved higher afterward), while two were purchased near inflection points where the stock subsequently declined, giving him a split record. The current purchase occurs in a company with solid fundamentals (profitable with modest revenue growth), though valuations appear elevated relative to earnings, and comes as the stock has retreated significantly from its recent peak and continues to trade near the lower end of its 52-week range. This is MacLennan's 15th open-market purchase over the past three years, reflecting a sustained pattern of accumulation with no offsetting sales, though the mixed outcomes on his prior Ecolab-specific trades suggest his timing at this particular stock is not consistently predictive.
