Context

• This was a routine tax-withholding sale tied to RSU vesting rather than an independent decision to sell shares, so it generally should not be interpreted as a signal of the insider’s view on the company. The weighted-average price reflects aggregated broker processing of multiple employees’ tax-withholding sales on the vesting date.
