Key points
- AMD's chief sales officer, Paul Darren Grasby, sold 15,000 AMD shares for $7.72 million on Aug. 17, 2026, with no 10b5-1 plan behind it.
- That "own call" tag just means he picked the date himself. It was his fifth open-market sale in a year, and he has never used a plan.
- He still holds about 117,700 AMD shares directly, worth around $57 million.
AMD's chief sales officer, Paul Darren Grasby, sold 15,000 AMD shares for $7.72 million on Aug. 17, 2026, at an average of $514.91. He didn't sell under a Rule 10b5-1 plan, so he chose the date himself, which is what AMD's insider data flags as an "own call." It was his fifth open-market sale in about a year, and he still holds about 117,700 shares.
The label is what makes this one look worse than it is. AMD's filing data tags Grasby's Aug. 17 sale as an "own call," which means he wasn't selling on a preset schedule. He looked at the stock that Monday and decided to sell $7.72 million of it. That reads like a sales chief heading for the door. Pull his other filings, though, and it looks a lot more like a routine he keeps every few months.
What the filing actually shows
Most of Grasby's Form 4 is ordinary pay, not selling he chose. On Aug. 15 a block of performance shares from a 2023 award vested and settled into common stock, and AMD automatically held back about 21,700 shares to cover the tax bill on that vesting. He also picked up a fresh round of grants the same day. None of that is a decision to sell anything. The one discretionary move on the form is the 15,000 shares he sold on the open market two days later, on Aug. 17.
The line worth reading slowly is the plan box. A checkbox near the top of every Form 4 marks whether a trade was "intended to satisfy the affirmative defense conditions of Rule 10b5-1(c)," the SEC's term for a sale scheduled far enough ahead that an insider can't be accused of trading on private information. Grasby's box is blank. So is the box on every open-market sale he has ever filed. He has never used a plan, so all of his selling counts as an "own call." We explained what that box means for a shareholder in a separate piece.
The timing was good. AMD closed at $506 that Monday, and Grasby's shares went at an average of $514.91, near the day's high. The stock has had a big year, up from the low $170s a year ago to a peak above $530 in early August. The morning after he sold, AMD fell about 4 percent, back near $485. The peak had come a couple of weeks earlier, but he still sold on one of the stock's stronger days.
Why this looks like habit, not a signal
This is where his older filings matter. Grasby sells a chunk of AMD every few months, and he always has.
| Date sold | Shares | Average price | Value | 10b5-1 plan? |
|---|---|---|---|---|
| Aug. 9, 2025 | 10,000 | $173.21 | $1.73 million | No, own call |
| Dec. 4, 2025 | 7,500 | $204.87 | $1.54 million | No, own call |
| Mar. 11, 2026 | 10,000 | $218.77 | $2.19 million | No, own call |
| May 8, 2026 | 24,376 | $444.39 | $10.83 million | No, own call |

Five sales in a year, about one a quarter, every one on his own call. The dollar figures climbed mostly because AMD climbed. The same 15,000-share sale that brought in $1.7 million last August is worth $7.7 million now, the same trade wearing a very different headline. This one wasn't even his largest. He sold about $10.8 million in May.
After Monday, he still holds about 117,700 AMD shares directly, worth around $57 million. A Form 4 records the trade and leaves the reason off the page. People in his seat sell to cover a tax bill or to buy a house, and plenty sell for the plain reason that too much of their money sits in one stock that has nearly tripled. What the filing shows cleanly is a sales chief selling a slice of a much larger stake, the same way he has all year. We ran the same check on two other names this month, the software firm Datadog and the chip-test maker Aehr.
