GWW W.W. GRAINGER, INC. Insider Trading

GWW SVP and CTO Leroy Jonny M sold 854 shares for $1.05M in five tranches on same day.

Leroy Jonny M, the company's Chief Technology Officer, executed five separate sales totaling approximately $1 million on a single trading day, reducing his direct stake from 2,408 shares to 1,554 shares. This represents his fifth open-market sale at Grainger in the filing window and fits a consistent pattern: over the past several months, this executive has engaged in 18 open-market sales while making zero open-market purchases. The sales occurred at prices ranging narrowly around $1,230 per share, suggesting he used limit orders or a systematic approach rather than opportunistic buying or panic selling. Grainger itself remains a solidly profitable company with recent quarterly results showing strong profitability, and annual revenue continues growing, providing a stable backdrop. The CTO's relentless selling pattern—particularly the absence of any offsetting purchases—warrants monitoring, though the narrow price range and deliberate execution suggest routine portfolio management rather than urgent capital need or loss of confidence in the company.

W.W. Grainger Sr. VP Robbins sells $1.8M in shares; pattern of exits follows mixed timing with long-term downside avoidance.

Robbins Paige K, Senior Vice President at W.W. Grainger, sold 1,457 shares totaling approximately $1.8 million across five transactions. This marks her tenth open-market sale at Grainger in the past three years—a consistent pattern of equity reduction with no offsetting purchases over that window. Her prior five sales at this company showed a striking timing dichotomy: all five were poorly timed over the 30-day horizon as the stock rose afterward, but all five proved well-timed over the 90-day horizon as the stock declined, suggesting her exits successfully avoided longer-term weakness even if short-term momentum worked against her initial exit prices. The company itself remains profitable and has grown revenue on an annual basis, providing no obvious financial deterioration as a trigger for the sale. The pattern—deep into a three-year cycle of equity dispositions with a track record of long-term downside avoidance—suggests disciplined portfolio management rather than crisis selling, though the absence of any open-market purchases in 36 months indicates she has not reinvested proceeds into company stock.

GWW CFO Merriwether sold 1,488 shares for $1,658,042.08 on 2026-04-02; stake reduced 12.4%.

Merriwether Deidra C, Senior Vice President and CFO of W.W. Grainger, executed 12 separate sales totaling 1,488 shares for $1,658,042.08 on April 2, 2026, at prices ranging from $1,097.27 to $1,118.61 per share (blended average $1,114.28). Her post-transaction holdings fell to 10,541 shares from 12,029 shares, reducing her stake by 12.4%. At the current price of $1,117.45, the stock stands 7.1% below its 52-week high and down 3.0% over 30 days despite an 11.3% gain over 90 days. Her cross-ticker sales history shows 20 prior open-market sells with a well-timed rate of 0.00% and a positive average 90-day return of 5.3% after sales—indicating her prior sales have generally not preceded declines. At GWW specifically, her prior five trades (all sales on 2026-03-24) lack measurable outcomes. The company's valuation (P/E 34.67) and recent financial performance (revenue growth 4.5% annually, Q-latest revenue of $4,657,000,000.00) provide context for evaluating the significance of this substantial reduction in her position.

CFO Merriwether sells 2,339 shares ($2.5M) in 12 transactions at GWW on 2026-03-24

Merriwether Deidra C, Sr. VP & CFO of W.W. Grainger, executed 12 separate sales totaling 2,339 shares for $2,490,393.39 at prices ranging from $1,044.84 to $1,072.56 on 2026-03-24, reducing her holdings by 18.6% to 10,235 shares. The blended average sale price was $1,064.73, compared to the current price of $1,075.87, placing the transaction 1.0% below current market levels. Her prior 5 sales at GWW (all on 2025-04-02) posted positive 90-day returns averaging +5.1%, indicating those earlier sales were not well-timed for capturing subsequent declines. The cross-ticker track record shows a 25.00% well-timed rate across 12 prior sells with mixed trailing performance, neither affirming nor contradicting timing acumen on this particular disposal.

Macpherson Donald G (then-CEO) sells 26,686 shares for $25,957,458.03 under pre-arranged 10b5-1 plan

Macpherson Donald G, who was CEO at the time, executed 22 separate sales totaling 26,686 shares for $25,957,458.03 across December 4-5, 2025, at prices ranging from $962.93 to $978.41. This transaction was part of a pre-arranged 10b5-1 trading plan adopted on 2025-09-04, making it a scheduled, non-discretionary sale. The sale reduced his holdings from 130,571 shares to 103,885 shares, a reduction of -20.4% of his pre-transaction position. Since the sale was pre-arranged rather than discretionary, the timing and price execution reflect the plan's mechanics rather than ad hoc decision-making. The blended average sale price was $972.70 across the two-day execution window.

VP, Controller Laurie R Thomson sold 761 shares for $793,614.84 at Grainger, reducing holdings by 56.8%

Thomson Laurie R, VP and Controller at W.W. Grainger, executed 8 separate sales on 2025-05-06 totaling 761 shares for $793,614.84 at a blended average price of $1,042.86. The sale reduced her holdings from 1,339 shares to 578 shares—a reduction of 56.8%. While the stock is trading at $1045.89 (near the blended transaction price and only -14.3% from its 52-week high of $1220.93), the substantial concentration reduction warrants attention. This is the only insider activity data provided; broader context on whether other executives are adjusting positions, or whether this reflects a systematic portfolio rebalancing plan, is not available from this filing alone.

GWW CFO Merriwether Deidra C sold 1,164 shares (10.2% of holdings) across 8 transactions for $1,160,644.00 at avg $997.12

Merriwether Deidra C, Senior Vice President & CFO of W.W. Grainger, executed 8 separate sales totaling 1,164 shares for $1,160,644.00 on 2025-04-02, reducing holdings from 11,399 to 10,235 shares. The transactions spanned a narrow $990.18–$1,002.99 price range with a blended average of $997.12, executed as the stock trades 20.3% below its 52-week high of $1220.93 and 2.5% below the current price of $973.41. Her prior GWW-specific trade history shows 3 of 4 previous sells were well-timed at the 90-day mark, with the most recent November 2024 sale delivering a 9.0% 30-day gain; cross-ticker track record shows a 75.00% well-timed rate across all holdings. The execution pattern and pricing suggest deliberate liquidation rather than scheduled plan activity, though the modest 10.2% reduction in holdings and the company's solid fundamentals (revenue $4.4B, P/E 24.59) context the magnitude of insider activity.

Sr. VP Robbins Paige K sold 9,577 shares ($10.7M) at GWW on 2024-11-05; reduced holdings to 4,379 shares (-68.6%)

Robbins Paige K, Sr. VP at W.W. Grainger, executed 9 separate sales totaling 9,577 shares for $10,705,600.58 at a blended average price of $1,117.84. This sale reduced his holdings from 13,956 shares to 4,379 shares, representing a -68.6% reduction. His prior 5 trades at GWW (all in February 2024) exhibited a consistent well-timing pattern at the 90-day mark—all 5 returned negative after 90 days (ranging from -5.6% to -6.7%), meaning he had previously sold before subsequent declines. Current price of $1,188.95 stands at -0.5% from the 52-week high of $1,194.96, and the stock is up +15.6% over the trailing 30 days and +21.4% over 90 days. The company's fundamentals remain solid with annual revenue growth of +8.2% and net income of $486,000,000.00 on revenue of $4,388,000,000.00 (P/E 31.65). The substantial reduction in his share position warrants tracking to see whether this disproportionate sale precedes a meaningful pullback, consistent with his historical pattern at this ticker.

CFO Deidra C Merriwether sold 704 GWW shares at $1,105.59; stock up 8.6% in 30d, near 52-week high

Deidra C Merriwether, Sr. VP & CFO of W.W. Grainger, sold 704 shares on 2024-11-01 for $778,336.70, reducing her holdings by 6.9% to 9,509 shares. The sale occurred at $1,105.59 while the stock has since climbed to $1,122.02, within 0.4% of its 52-week high of $1,127.00, following a strong 30-day rally of +8.6% and 90-day gain of +18.0%. Her cross-ticker track record shows 3 prior sells with a 90d well-timed rate of 100.00%, and at GWW specifically, all 3 prior sales (all on 2024-02-08) achieved negative 90-day returns averaging -0.2%, indicating historically well-timed exit points. This transaction reverses that pattern: the stock has appreciated post-sale in the immediate term, suggesting the sale preceded a continued advance rather than a decline. Against a backdrop of solid fundamentals—annual revenue growth of +8.2%, quarterly revenue of $4,388,000,000.00, and net income of $486,000,000.00—the sale does not appear to signal operational concern but rather reflects portfolio rebalancing at a valuation near historical highs.

Macpherson, then-CEO, sold 12,992 shares for $13,481,557.42 under pre-arranged 10b5-1 plan

On 2024-09-30, Macpherson Donald G, who held the title of Chairman and CEO at the time of filing, executed 12 separate sales totaling 12,992 shares for $13,481,557.42 at prices ranging from $1,032.23 to $1,043.84. This transaction was part of a pre-arranged 10b5-1 trading plan adopted on 2024-06-17, meaning it was scheduled rather than discretionary. The sale reduced his holdings from 111,559 shares to 98,567 shares, a decrease of 11.6% of his pre-transaction position. As a Form 4 for the issuer's Chairman and CEO, this represents a material reduction in insider exposure to GWW equity during a scheduled plan window.
