Rodman David Malcom, Chief Medical Officer at Mineralys Therapeutics (MLYS), has been a consistent seller of company stock over the past two months, with no open-market purchases recorded during the period. Across 91 total Form 4 filings, his transactions show a complete absence of buy-side activity, while sell-side trades total approximately $15.1 million. The recent pattern is particularly one-sided: 11 sales between May 12 and July 17, 2026, ranging from roughly $11,000 to $402,000, with the largest single disposition occurring on May 13 at $401,789. The sales cluster around option exercises (coded M), which are mechanical conversions of existing awards, followed immediately by open-market sales (coded S) of the underlying shares.
The most recent activity on July 17 shows a small sale of $11,036 alongside an option exercise valued at $6,423, continuing the established rhythm of exercise-and-sell transactions. Earlier in the week, Malcom sold $168,955 on July 15 and $387,717 on July 13, with the latter accompanied by three separate option exercises totaling roughly $102,365. The pattern extends back through June and May, with notable sales of $235,487 on June 15, $151,901 on June 12, and $186,348 on May 12. Each sale is paired with option exercises of similar magnitude, suggesting the transactions are part of a systematic approach to monetizing vested equity rather than discretionary market timing.
The data reveals no purchases, gifts, or sales back to the issuer—only the consistent conversion of options into cash. The dollar values of the option exercises are modest relative to the sale proceeds, indicating that Malcom is selling shares acquired at low strike prices for substantial gains. The frequency and regularity of the transactions, occurring roughly every few days during the reporting window, point to a predetermined selling schedule rather than reactive trading. All activity is confined to MLYS, with no diversification into other tickers, and the absence of any buy-side conviction signals a clear net-selling bias over the observed period.
