Context

• This filing reflects a compensation award (RSUs) and routine issuer withholding to cover taxes. The withholding was a net settlement mechanism rather than an open-market sale by the insider. Awards and withholding are common forms of executive compensation and tax compliance; they are not direct buy/sell signals about the insider’s market view.
