Context

The 854-share conversion reflects RSU vesting (each RSU converts to one share); the immediate disposition of those shares at $0.00 reflects shares surrendered/withheld to cover tax withholding, not an open-market sale for cash.
The larger sales on 3/16–3/17 were open-market disposals, with the 3/17 sale executed under a prearranged 10b5-1 plan — such prearranged plans are commonly used to automate sales and do not by themselves indicate a change in insider sentiment.
