Context
- These entries reflect RSU vesting and a routine sell-to-cover tax withholding, not an independent open-market purchase or a discretionary sell for investment reasons. The RSUs were converted at no cash cost and some of the resulting shares were sold immediately to pay taxes.
- Sell-to-cover transactions are common when equity awards vest and do not necessarily signal the insider’s view on the company’s stock.
