ECL ECOLAB INC. Insider Trading

EVP Benjamin M. Clark purchases 1,000 shares of ECL at $263.83; holdings grow to 1.1K shares (+1210.9%)

Benjamin M. Clark, EVP of Global Supply Chain at Ecolab, purchased 1,000 shares at $263.83 on 2026-06-11, increasing his holdings from 82 shares to 1,082 shares—a net increase of +1210.9% relative to his pre-transaction position. The purchase occurred when ECL traded near its 52-week high, with the stock at $268.58 currently and a 52-week range of $243.15–$309.27. For context, Ecolab reported quarterly revenue of $4.1B and net income of $432.6M, with annual revenue growth of +2.2% and a P/E ratio of 35.91. The magnitude of this accumulation—growing his position from a minimal 82 shares to over 1,000 shares in a single transaction—represents a material absolute increase in his stake, though his post-transaction holdings of 1.1K shares remain modest relative to the company's $75.6B market cap.

Director Michel D Doukeris buys 7,750 shares of ECL at $258.00; holdings jump 1344.9% to 8,326 shares

Michel D Doukeris, a Director of Ecolab Inc., purchased 7,750 shares at $258.00 on 2026-06-10 for a total value of $1,999,500.00, expanding his post-transaction holdings to 8,326 shares from a pre-transaction position of 576 shares—a net increase of 1344.9%. The purchase price of $258.00 sits below the current price of $263.63 and well below the 52-week high of $309.27, occurring at a point -14.8% from the 52-week peak. This substantial equity commitment by a Director in a $74.2B market-cap company with P/E of 35.24 represents a material expansion of personal economic exposure to the firm's performance.

Co-COO Darrell R Brown sold 10,000 ECL shares at $260.89; holds 32,733 shares post-sale

Darrell R Brown, Co-COO of Global Markets, executed a sale of 10,000 shares at $260.89 on 2026-06-09, reducing his non-derivative holdings from 42,733 to 32,733 shares. The stock currently trades at $256.99, down -16.9% from its 52-week high of $309.27, and the insider retains a material stake of 32,733 shares. ECL trades at a P/E of 34.36 with a market cap of $72.3B and reported latest-quarter revenue of $4.1B and net income of $432.6M. The sale occurred while the stock trades below its recent high, and the insider's remaining position suggests continued alignment with the company despite the reduction.

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.

EVP Gregory B Cook sold 3,519 shares of ECL at $304.25 on 2026-02-26; post-sale holdings 11,673 shares.

Gregory B Cook, EVP & President of Ecolab's Institutional Group, sold 3,519 shares (3.5K shares) for total value of $1,070,655.75 ($1.1M) at a price of $304.25. The sale reduced his holdings from 15,192 shares (15.2K shares) to 11,673 shares (11.7K shares), representing a net change of -23.2% versus pre-transaction holdings. The transaction occurred at a price below the current market level of $308.35 and below the 52-week high of $308.35, where the stock now trades. This sale by a senior executive should be monitored in context of Ecolab's current valuation (P/E of 44.62) and modest annual revenue growth of +2.2%, though the stock has appreciated 9.6% over the past 30 days and 12.1% over 90 days.

CEO Beck Christophe sells 20,000 ECL shares for $6,147,361.52 at $307.37 blended avg

Beck Christophe, Chairman & CEO of Ecolab, executed two separate sales totaling 20,000 shares for $6,147,361.52 at a blended average price of $307.37 on 2026-02-24, reducing his holdings by 18.1% from 110,794 to 90,794 shares. The transaction occurred near the 52-week high (current price $306.52 is -0.5% from the $308.16 peak), and the stock has appreciated +8.1% over the past 30 days and +11.5% over 90 days. At this specific ticker (ECL), none of Christophe's 5 prior sales over the past two years were well-timed by the 90-day mark; his most recent sales in November 2025 preceded a continued advance (+14.7% and +14.2% over 90 days). His cross-ticker track record shows a 0.00% well-timed rate on 6 prior sells with an average 90-day return of +6.8%, indicating recent sales have typically occurred before subsequent price appreciation rather than ahead of declines. This sale does not signal a tactical reposition given the company's solid fundamentals (P/E of 44.36, $4.2B quarterly revenue, +2.2% annual growth, $585.0M net income).

EVP & PRES - GLOBAL WATER Alfano sells 9,501 shares (66.8% reduction) of ECL at $303.58, reducing holdings to 4,721 shares; stock near 52-week high.

Alfano Nicholas J., EVP & President of Global Water, sold 9,501 shares for $2,884,313.58, representing a 66.8% reduction in his ECL holdings from 14,222 to 4,721 shares. The sale occurred at $303.58, very close to the 52-week high of $303.80 and significantly above the current price of $302.59. His prior two sales at ECL (May 2025 at +5.2% 30-day return and November 2023 at +4.6% 30-day return) both resulted in positive 90-day returns (5.0% and 18.7% respectively), indicating the stock continued rising after his previous exits—a pattern of poorly-timed sells at this ticker. Against this backdrop, a substantial reduction in an executive's core holdings at near-peak valuation warrants close observation of whether circumstances have shifted materially at the company or in his role.

Director MacLennan David bought 750 shares of ECL at $257.60; holdings rise to 23,035 shares (+3.4%)

Director MacLennan David purchased 750 shares at $257.60 on 2025-12-08, increasing his shareholding by 3.4% to 23,035 shares. His cross-ticker track record shows 12 prior buys with a 63.64% win rate and average 90-day return of +5.3%, though at ECL specifically his prior five purchases show mixed outcomes: 3 of 5 were well-timed (positive 90-day returns), while the two most recent buys (on 2025-08-13 and 2025-05-07) have seen the stock decline -5.9% and rise +5.8% respectively at the 90-day mark. The current price of $257.15 is -9.9% below the 52-week high of $285.47, placing the purchase 2.5 cents below current levels. This is a discretionary open-market purchase by a director of a $72.8B market-cap company with $4.2B quarterly revenue, though the modest transaction value ($193,197.75) and mixed same-ticker timing history provide limited directional clarity.

CEO Beck Christophe sells 21,714 shares of ECL for $5,676,232.61 across 2 transactions; holdings fall 23.0% to 72,644 shares

Beck Christophe, Chairman & CEO, sold 21,714 shares (21.7K) across 2 separate transactions on 2025-11-12 at blended average price $261.41, raising $5,676,232.61 (total proceeds). This represents a 23.0% reduction in his ECL holdings from 94,358 to 72,644 shares post-transaction. Ecolab trades at a P/E of 37.37 with market cap of $74.2B; the stock is currently -8.2% from its 52-week high and down 4.0% over the prior 30 days. Looking at his same-ticker history at ECL, his 4 prior trades at this company showed mixed outcomes: two 2024 sales followed the stock upward (90-day returns of +1.6% and +1.2%), while two 2023 sales also preceded modest gains (+4.7% and +4.2%), with none timing the subsequent 90-day decline. The material scale of this sale—representing nearly one-quarter of his pre-transaction holdings—merits observation, though the 72.6K shares remaining leave him with a substantial position.
