What this transaction means for investors
CEO Jon Congleton’s March 31 sale of 75,000 Mineralys Therapeutics shares is not necessarily a warning sign for investors. He executed the transactions as part of his Rule 10b5-1 trading plan, adopted in December of 2025.
A Rule 10b5-1 trading plan is often implemented by insiders to avoid accusations of making trades based on insider information. Moreover, Congleton maintained over 700,000 shares after the sale, so he retains a sizable stake in the company.
Mineralys stock has dropped quite a bit in 2026 from the 52-week high of $47.65 reached last November. Shares fell after the company reported in March that clinical trials of its lorundrostat treatment showed no clinically meaningful difference compared to a placebo.
For lorundrostat to achieve federal approval, it needs to show that it can assist with hypertension. As a result, owning shares in Mineralys is a risky investment. The best approach for shareholders and those thinking about buying the stock is to wait to see how the company’s treatment progresses in the coming quarters.
