AMD CTO Sells $10 Million in Shares Amid AI Rally

Mark D. Papermaster, Chief Technology Officer and Executive Vice President of U.S. semiconductor firm Advanced Micro Devices, Inc. (AMD), sold tens of thousands of AMD common shares under a Rule 10b5-1 trading plan on April 6, April 15–16 and April 24. The April 24 transaction alone was disclosed at approximately USD 10.96 million (around KRW 15 billion).

Following these sales, Papermaster still holds roughly 1.23 million AMD shares—directly and indirectly. As of mid-April, the value of his directly held shares stood at about USD 349 million (approximately KRW 480–500 billion), underscoring his continued significant economic stake in the company.

On April 8, AMD announced it will report its first-quarter fiscal 2026 results after market close on May 5 (U.S. Eastern Time). Over the past few weeks, AMD’s share price has surged more than 30%, reaching a 52-week high on April 22 amid growing expectations for AI data-center demand. Analysts also point to potential European market expansion—highlighted by an AI collaboration deal with the French public sector—as supporting the stock’s rise to about USD 348 at the April 24 close.

AMD, a leading U.S. fabless semiconductor designer of CPUs and GPUs for PCs, gaming consoles and data centers, achieved record 2025 results with USD 34.6 billion in revenue and a 50% gross margin. Papermaster has overseen microprocessor design and major product roadmaps as AMD’s CTO and head of Technology & Engineering since 2011. His recent share sale is classified as a routine transaction under the Rule 10b5-1 plan he adopted in November 2025.
