What Happened

• Mark D. Papermaster, Chief Technology Officer & EVP of AMD, exercised stock options and converted derivative awards on August 14–15, 2026, and sold a small block in the open market. He sold 7,369 shares at $487.34 for proceeds of $3,591,208. To satisfy tax/withholding obligations related to the exercises, 46,796 shares and 1,203 shares were withheld at $514.39 for a total withholding value of $24,690,205. The filings also report awards (PRSUs/RSUs) granted: 11,855 and 7,903 shares (contingent/vesting awards).

Context

• Mechanics: This looks like option exercise(s) followed by immediate share disposition/withholding to cover exercise costs and taxes (a cashless-style exercise). The open‑market sale (7,369 shares) was executed under the 10b5‑1 plan, which pre‑establishes trade timing.
• Codes: M = option exercise/conversion; S = sale; F = shares withheld for tax/exercise; A = award/grant.
• Interpretation: Sales and withholding to cover taxes are commonly administrative (not necessarily a signal of conviction). Purchases would generally be more indicative of bullish insider sentiment; here the filing mainly shows option exercise and tax‑related withholdings plus a small planned sale. All items were filed timely.
