Context
- These were open-market sales executed under a pre-established 10b5-1 plan, a common mechanism insiders use to sell shares according to pre-set rules. That structure helps insulate the trades from being viewed as based on nonpublic information. Sales do not necessarily indicate a change in outlook on the company.
