Context

• These were open-market sales made under a pre-established 10b5-1 plan, which typically means the trades were scheduled in advance and do not necessarily indicate the insider’s current view of the company. Sales reduce insider stock holdings but are often routine; purchases are generally viewed as a stronger signal of insider confidence.
