Mark D Papermaster, Chief Technology Officer & EVP, sold 6,000 shares of AMD on 2026-07-15 at $556.43 for total value of $3,338,580.00 as part of a pre-arranged 10b5-1 trading plan adopted on 2025-11-14. This is a scheduled, non-discretionary transaction. His post-transaction holding of 1,233,687 shares represents a -0.5% reduction from his 1,239,687 pre-transaction shares, and he retains 7,369 shares through stock option grants. His same-ticker history at AMD shows 5 prior sells with measurable outcomes ranging from -1.3% to +114.5% in 90-day returns, reflecting a pattern of variability in post-sale price movement. The stock currently trades at $495.76, down -15.2% from its 52-week high of $584.73, though up +78.1% over 90 days.

AMD CTO Mark Papermaster sold 6,000 shares at $536.33 on 2026-06-15 under pre-arranged 10b5-1 plan; holds 1.23M shares post-transaction.

Mark D Papermaster, Chief Technology Officer & EVP, sold 6,000 shares (6.0K shares) of Advanced Micro Devices Inc (AMD) at $536.33 on 2026-06-15 for a total value of $3,217,980.00 ($3.2M), reducing his non-derivative holdings from 1,239,687 shares (1.24M shares) to 1,233,687 shares (1.23M shares)—a reduction of 0.5% of pre-transaction holdings. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2025-11-14, meaning it is scheduled and non-discretionary rather than an expression of current conviction. The current stock price of $512.48 sits 8.2% below the 52-week high of $558.37; over the past 90 days the stock has risen 149.7%, and over the past 30 days it has risen 21.7%. Notably, Papermaster's five prior open-market sales at AMD (on 2026-04-06, 2026-04-15, 2026-04-16, 2026-04-24, and 2026-05-15) all posted positive 30-day returns ranging from 17.9% to 87.3%, indicating the stock continued to appreciate after each sale. The insider retains derivative holdings (stock options) of 13,369 shares, so his overall position remains active.

AMD CTO Papermaster sells 6,000 shares ($2.6M) via 10b5-1 plan; stock up 48.7% in 30 days, 106.9% in 90 days

Mark D Papermaster sold 6,000 shares at $433.79 on 2026-05-15 under a pre-arranged 10b5-1 trading plan adopted on 2025-11-14, reducing holdings to 1,233,687 shares from 1,239,687 shares. This sale is contractually scheduled rather than discretionary. AMD's stock has appreciated sharply post-transaction: +48.7% over 30 days and +106.9% over 90 days from the sale date, while currently trading at $414.05 (down 11.8% from its 52-week high of $469.22). Across his five prior AMD trades, Papermaster's average post-transaction returns have been positive (ranging from +8.8% to +87.3% at 30/90-day intervals), yet the scheduled nature of the 10b5-1 plan means this particular sale was not a discretionary timing decision but rather an execution of a predetermined schedule.

C-suite executive sells ~31K AMD shares worth ~$11M near recent highs

An AMD executive sold approximately 31,000 shares for roughly $11 million, representing a meaningful reduction of their shareholding. The sale occurred when the stock was trading only slightly below its recent high, suggesting the executive took advantage of strong price momentum rather than selling into weakness. AMD is a profitable company with robust revenue growth and expanding earnings, though its valuation appears stretched relative to near-term earning power. This sale warrants attention because it reflects confidence in the current stock price but also a desire to diversify holdings or lock in gains after a substantial rally. Without visibility into the executive's historical trading patterns or proximity to material announcements, the significance falls into moderate territory—notable enough to monitor but not immediately alarming.

AMD CTO Mark Papermaster sold 33,109 shares for $8,988,215.00 across two April transactions; stock now at 52-week high.

Mark Papermaster, Chief Technology Officer & EVP, executed two separate sales totaling 33,109 shares for $8,988,215.00 on April 15–16, 2026, at blended average price of $271.47. His holdings remain substantial at 1,267,357 shares post-transaction (-2.5% vs pre-transaction), and AMD's stock has since appreciated to $278.39 (the 52-week high). Within his broader cross-ticker track record, his prior 20 sells showed 83.33% well-timed outcomes at the 90-day mark; at AMD specifically, three prior sells executed in November 2025 all achieved negative 90-day returns, indicating accurate exit timing at that ticker. The current sale occurs at a compressed valuation (P/E 75.65) following a +39.6% 30-day price surge and +34.3% revenue growth, setting up a meaningful timeline for assessing whether this transaction aligns with his consistent pattern of downside-accurate sales at the 90-day horizon.

AMD CTO Papermaster sells 3,293 shares at $225.00; post-sale holdings 1,294,466 shares; stock near 52-week high.

Mark D. Papermaster, Chief Technology Officer & EVP, sold 3,293 shares of AMD at $225.00 on 2026-04-06, reducing his holdings by 0.3% to 1,294,466 shares. This sale occurs when AMD trades at $231.82, only -12.3% from its 52-week high of $264.33, and follows a 30-day gain of +14.4%. At the same-ticker level, Papermaster's prior four AMD sales were well-timed at the 90-day mark, all showing negative subsequent returns ranging from -10.6% to -13.4%. His cross-ticker track record shows 20 prior sells with a 78.95% well-timed rate, indicating a consistent pattern of selling near peaks. The current transaction, positioned within 33 days of a prior AMD sale on 2026-03-04 (which itself gained +8.8% in 30 days), suggests continued disciplined execution rather than panic or distress selling.

AMD CTO Mark Papermaster sells 3,034 shares at $200.00 under pre-arranged 10b5-1 plan from March 2025.

Mark Papermaster, Chief Technology Officer & EVP, executed a scheduled sale of 3,034 shares at $200.00 on 2026-03-04 under a 10b5-1 trading plan adopted on 2025-11-14. Post-transaction holdings stand at 1,297,759 shares, representing a -0.2% reduction in his position. Because this transaction is part of a pre-arranged plan, it reflects a programmatic execution rather than a discretionary market decision, limiting what this trade reveals about his near-term conviction regarding AMD's business prospects.

CTO Mark Papermaster sold 17,108 shares ($4.1M) across 9 transactions at $235.87–$243.98 on 2025-11-14; retains 1.71M shares.

Mark Papermaster, Chief Technology Officer & EVP of AMD, executed 9 separate sales totaling 17,108 shares for $4,107,935.15 on 2025-11-14, representing a 1.0% reduction in his 1.73M-share position. The blended average price of $240.12 came as the stock traded near its 52-week high of $264.33, positioning this sale 12.9% below peak valuation. His prior trades at AMD (5 consecutive sales on 2025-10-15) showed 30-day returns of +9.1% to +11.5%, indicating the stock has continued to rise after his recent sales; his cross-ticker track record shows a 0.00% well-timed rate on 20 prior sells with an average 90-day return of +42.8%, suggesting a pattern of selling into upward momentum rather than ahead of declines. The AMD fundamentals remain solid (P/E 113.44, net income $1.2B, annual revenue growth +13.7%), though the high valuation multiples warrant attention given the timing of this executive-level reduction.

CTO Mark Papermaster sold 16,800 shares at $224.28 avg for $3.8M on 2025-10-15; stock up 46.4% in 30d.

Papermaster executed 6 separate sales totaling 16,800 shares (1.0% of pre-transaction holdings) at prices ranging from $221.42 to $226.17, generating $3,767,862.67 in proceeds. The timing coincides with strong recent momentum—AMD shares are up 46.4% over the prior 30 days and up 48.5% over 90 days, now trading at $233.08, only 2.3% below the 52-week high of $238.60. His same-ticker history at AMD shows recent sells on 2025-09-15 that captured +49.4% and +50.0% gains within 30 days, though his cross-ticker track record indicates a 0.00% well-timed rate across 20 prior sells, suggesting his historical sales have not systematically preceded declines. The company's strong fundamentals—$7.7B quarterly revenue, 13.7% annual growth, and $872M net income—provide operational context, though the elevated P/E of 133.19 warrants attention given the outsized valuation relative to near-term earnings.
