Grant Michael Dixton, a President at General Motors Co ($GM), sold 40,000 shares of company stock on August 3, 2026, at a price of $88.44 per share, for a total transaction value of $3,537,600. The sale was conducted on the open market and disclosed in a Form 4 filing with the Securities and Exchange Commission the same day. Following the transaction, Dixton held 54,992 shares of $GM.
The filing marks the first Form 4 trade reported for Dixton in the InsiderTradingTracker database. A review of SEC records shows no prior open-market transactions under his name. The 40,000-share sale represented approximately 42% of the 94,992 shares he held before the transaction. The Form 4 was filed on the same day as the trade, meaning there was no disclosure delay.
Dixton's sale occurred during a period of elevated insider selling activity at General Motors. Two other $GM presidents executed open-market sales during the prior week. On July 27, Rory Harvey sold 8,882 shares at $86.95 per share, totaling $772,290. On July 28, Christopher Hatto sold 6,895 shares at $90.00 per share, totaling $620,550. Both transactions were disclosed in filings dated July 29 — a delay of two days and one day, respectively. $GM employs multiple executives holding the President title across its various business units.
For the trading week of July 27 through July 31, $GM shares traded in a range of $84.095 to $91.85, based on daily pricing data. The stock closed at $88.86 on July 31, the final trading day before Dixton's sale. Dixton executed his transaction at $88.44, a price within 0.5% of that closing level.
