Context

• These were awards and PSU settlements, not open-market purchases or sales, so they represent compensation/performance settlement rather than a direct market bet by the insider. For retail investors, awards can dilute existing shares as they vest/settle; the Restricted Stock Award has multi-year vesting, while the PSUs reflect performance achievements for prior grant years.
