Context
These were open-market sales (transaction code S). Sales by directors can be for many personal or financial reasons and do not, by themselves, prove a change in company outlook — purchases tend to be more informative about insider sentiment. Retail investors should view this as a reported insider disposal totaling ~22,000 shares and $1.61M in proceeds, and consider it alongside other filings and company fundamentals.
