Context

• The August 14 entries reflect conversion/settlement of performance stock units, with an issuer-mandated disposition/withholding of shares to cover taxes — common practice for equity awards. The August 18 sales were open-market disposals of shares; such sales tied to vesting and tax withholding are routine and do not necessarily indicate the insider’s view on the company’s prospects.
