Director Brian Taylor Slingsby sold 1,000,000 shares of MLYS for $43,350,000 on 2025-11-20; holds 7,903,838 post-trade.
Director Brian Taylor Slingsby executed a substantial sale of 1,000,000 shares at $43.35, reducing his position by 11.2% while generating $43,350,000 in proceeds. The sale occurred near the company's 52-week high ($47.33), with the stock down only 0.4% over the past 30 days but up 181.3% over 90 days, suggesting a recent appreciation period. Mineralys remains unprofitable with a negative full-year net income of $-36,932,000, which provides important context for director-level equity reduction. His prior open-market sell at MLYS on 2024-07-24 exhibited poor 90-day timing (the stock rose 6.9% afterward), and his cross-ticker sell track record shows a 0.00% well-timed rate, indicating his historical sales have not consistently preceded stock declines.
