Rory Harvey, Executive Vice President of General Motors, sold 9,124 shares at $84.97 on 2026-05-28, reducing his holdings by 19.6% from 46,519 to 37,395 shares. This transaction is part of a pre-arranged 10b5-1 trading plan, meaning it was scheduled rather than discretionary. The current stock price of $82.68 is -5.6% from the 52-week high of $87.62, and the sale occurred above current levels. Reviewing Harvey's prior trades at GM specifically, his five most recent trades show mixed 90-day outcomes: three 2025-08-05 sales with 90d returns of +28.6%, +29.5%, and +27.9%; one 2024-11-25 sale with a 90d return of -22.9%; and one 2024-10-23 sale with a 90d return of -0.2%.

Christopher Hatto executed a scheduled sale of 6,895 shares under a pre-arranged 10b5-1 trading plan, reducing his GM holdings from 32,689 shares to 25,794 shares. The sale occurred at $85.00 per share for total value of $586,075.00. Since this transaction is part of a pre-arranged plan, it reflects administrative execution rather than discretionary timing. Hatto's prior five trades at GM have posted mixed near-term outcomes: his prior sells generated 30-day returns ranging from +3.8% to +14.2%, while his cross-ticker track record shows an average 90-day return of +25.5% following sales. The company's fundamentals show $43.6B in quarterly revenue and $2.6B net income, though annual revenue growth is flat at -1.3% year-over-year.

Significance 6

GM CEO Mary Barra sells 453,402 shares for $37.2M across 7 transactions via 10b5-1 plan (2026-05-26 to 2026-05-28)

Mary T Barra (Chair & CEO) executed 7 separate sales totaling 453,402 shares for $37,192,224.77 between May 26–28, 2026, at prices ranging from $80.01 to $85.03 per share. This represents a -43.4% reduction in her non-derivative holdings, bringing them from 1,045,644 shares to 592,242 shares post-transaction. The sale is part of a pre-arranged 10b5-1 trading plan, meaning it was scheduled and non-discretionary. Notably, Barra retains 845,962 shares in derivative holdings (four tranches of employee stock options), so her overall economic interest in GM remains substantial. The current stock price of $84.12 is -4.0% from the 52-week high of $87.62 and +7.9% over the 30-day period preceding this filing, placing the transaction within a recent uptrend in the stock.

CFO Paul A Jacobson sold 40,000 GM shares at $80.00 on 2026-05-26 via pre-arranged 10b5-1 plan; holds 425,675 shares post-sale.

Paul A Jacobson, EVP & CFO, sold 40,000 shares for $3,200,000.00 under a pre-arranged 10b5-1 trading plan, reducing his holdings to 425,675 shares. The sale occurred at $80.00 per share when the stock currently trades at $84.12, within its 52-week range of $46.82–$87.62. Because this transaction is scheduled under a 10b5-1 plan rather than discretionary, it reflects a pre-set divestiture schedule rather than a timing-driven decision. His cross-ticker track record shows 1 prior buy with +10.1% average 30-day return and +19.5% average 90-day return at 100% win rate, though this represents limited data and does not establish a predictive pattern specific to GM, where he has executed only 1 prior measurable trade (a buy in 2024).

Significance 6

GM EVP Rory Harvey sells 85,146 shares in 3 transactions for $7,049,301.54 via 10b5-1 plan

Rory Harvey executed 3 separate sales totaling 85,146 shares for $7,049,301.54 between May 22–27, 2026, reducing his non-derivative holdings from 131,665 shares to 46,519 shares (-64.7% vs pre-transaction holdings). This transaction is part of a pre-arranged 10b5-1 trading plan and therefore scheduled rather than discretionary. Harvey's prior open-market history across all tickers shows 9 sells with an average 90-day return of +13.3%, and his 5 prior GM-specific sells each yielded positive 30-day and 90-day returns; however, the 10b5-1 flag indicates timing characterization is not applicable to this filing. GM's fundamentals show quarterly revenue of $43,624,000,000, net income of $2,627,000,000, and a P/E of 29.83; the stock is trading at $84.12, approximately -4.0% from its 52-week high of $87.62.

GM President Reuss sells 480,724 shares for $38.7M across 4 transactions on 2026-02-17, reducing holdings by 83.9%

Mark L Reuss, GM President, executed 4 separate sales totaling 480,724 shares (480.7K shares) for $38,709,454.92 ($38.7M) on 2026-02-17, with a blended average price of $80.52. This sale reduced his holdings from 573,017 shares (573.0K shares) to 92,293 shares (92.3K shares), a reduction of 83.9% versus pre-transaction holdings. The shares sold at prices ranging from $80.10 to $80.94, near recent trading levels but 3.1% below the current price of $83.67 and well below the 52-week high of $86.38. His prior trades at GM show a consistent pattern: 5 prior sales all generated positive 90-day returns (ranging from +5.8% to +37.9%), meaning none were well-timed in the traditional sense (stock rose after he sold). This transaction's true significance depends on whether it reflects liquidity needs, estate planning, or other personal considerations rather than a signal about GM's near-term prospects, particularly given the company's recent fundamentals show -1.3% annual revenue growth and an elevated P/E of 25.13.

Significance 4

VP & CAO Hatto Christopher sold 7,724 shares of GM at $72.00 for $556,128, reducing holdings by 39.1% to 12,007 shares

Hatto Christopher, serving as Vice President & CAO, sold 7,724 shares at $72.00 on 2025-11-12, representing a -39.1% reduction in his GM holdings from 19,731 to 12,007 shares. At the transaction price of $72.00, this sale occurred at the 52-week high of $71.89, consistent with his recent trading pattern at GM where he has executed five sales over the past three months (2025-08-13, 2025-08-27, 2025-09-26 twice, and 2025-10-28). His cross-ticker track record shows 8 prior open-market sells with a 90-day well-timed rate of 0.00%, meaning none of his recent sales across all holdings preceded stock declines; his same-ticker history at GM shows 0 of 1 measurable prior sales were well-timed at the 90-day mark. The high volume of sales within a compressed timeframe at elevated valuations warrants monitoring, though the fundamental backdrop shows reasonable metrics with revenue growth of 9.1%, a P/E of 21.98, and market cap of $67,063,399,072.67.
