Papermaster Mark D

Papermaster Mark D, Chief Technology Officer and EVP at Advanced Micro Devices, has filed 96 Form 4 transactions across two companies, with a total sell value of $73,620,236.76 and zero open-market purchases. The pattern is entirely one-directional: every discretionary trade is a sale of AMD stock, and the recent activity confirms that bias. In the last month alone, Papermaster executed ten open-market sales on August 20, 2026, with individual values ranging from $187,940 to $4,517,235.05. Combined, those ten transactions totaled roughly $12.6 million. He also sold $3,591,208.46 on August 14 and $3,338,580 on July 15. The August 15 filings show the mechanical side of his holdings. Papermaster received two grants (code A) and exercised multiple options (code M), all valued at zero in the filing, which is standard for exercises. Those exercises triggered two tax-withholding events (code F) worth $618,811.17 and $24,071,394.44, the latter being the largest single line item in the recent data. A gift of zero value on August 19 rounds out the non-sale activity. None of these codes represent a purchase; they are compensation, option conversions, or automatic withholdings. The selling is consistent and concentrated in AMD. Papermaster has not bought a single share on the open market across his entire filing history, and the recent trades show no change in that stance. The August 20 cluster, with eight separate sale lines on one date, suggests a scheduled disposition of a large block, but the filings do not indicate whether the transactions were prearranged under a 10b5-1 plan. The data shows a steady seller of AMD stock, with the most recent sales occurring in the third week of August 2026.
