What this transaction means for investors
The complete disposition of all directly-held Maze Therapeutics shares on April 1 by Chief Medical Officer Harold Bernstein is not necessarily a red flag. He sold the stock as part of his Rule 10b5-1 trading plan, adopted in September of 2025.
A Rule 10b5-1 trading plan is frequently implemented by insiders to avoid accusations of making trades based on insider information. Moreover, he retains over 237,000 stock options.
Bernstein’s sale came at a time when Maze Therapeutics stock was experiencing a decline. Shares hit a 52-week high of $53.65 in March, thanks to encouraging clinical trial data. But with a soaring valuation, investors began cashing in, which led to the drop.
Currently, Maze Therapeutics does not produce revenue. It exited 2025 with a net loss of $131.1 million. Despite the recent fall in share price, investing in the company entails high risk. Investors should have conviction that its lead kidney drug, MZE829, can eventually achieve federal approval before deciding to buy shares.
