GWW Chairman/CEO Macpherson sold 26,686 shares for $25,957,458.03 across 22 transactions on Dec 4–5, 2025.

Donald G Macpherson, Chairman and CEO of W.W. Grainger, Inc. (GWW), executed 22 separate sales totaling 26,686 shares for $25,957,458.03 at a blended average price of $972.70 on December 4–5, 2025. This represents a -20.4% reduction in his pre-transaction holdings (from 130,571 to 103,885 shares). The transaction occurred against a backdrop of GWW trading near year-to-date lows: the current price of $959.07 is -19.6% from the 52-week high of $1193.16, though the company fundamentals remain solid with $4.7B in latest-quarter revenue, $294.0M net income, and a 26.36 P/E multiple. His prior trades at GWW (5 sells since September 2024) averaged +5.8% 30-day returns and +3.5% 90-day returns but were all poorly timed at the 90-day mark; similarly, his cross-ticker track record shows 20 prior sells with a 0.00% well-timed rate, indicating a historical pattern of selling before rallies rather than before declines. The sheer volume and deliberate multi-tranche execution of this large open-market sale warrants monitoring for shifts in his capital allocation or convictions regarding the company's near-term prospects.

GWW CEO Macpherson sells 12,992 shares for $13,481,557.42; reduces stake by 11.6% near 52-week peak.

The sales were distributed across prices ranging from $1,032.23 to $1,042.96 per share, with a blended average of $1,037.68, occurring when GWW was at -0.4% from its 52-week high of $1043.93. His cross-ticker track record shows 20 prior sells with a 0.00% well-timed rate (lower is worse for sells), while his 5 prior GWW trades on 2024-09-16 remain unmeasurable. The company's fundamentals remain solid with $4.3B in latest quarterly revenue, +8.2% annual growth, and $50.8B market cap, though the P/E of 27.92 reflects elevated valuation.
