Context

• This was a routine vesting-and-tax-withholding transaction: PSUs vested and converted to shares, and some of those shares were sold solely to cover tax obligations. Such sell-to-cover sales are common and do not necessarily signal the insider’s view on the company’s outlook.
• The derivative entries reflect the conversion/settlement of PSUs (not an options purchase).
