The instructions reference Stock Unit Agreements dated January 26, 2024 (F1) and January 27, 2023 (F2).

Context

• These were routine sales to cover tax obligations on vested RSUs, not open-market purchases or option exercises. Sales made to satisfy withholding are common and do not necessarily signal a change in the insider’s view of the company.
• The use of written instructions intended to meet Rule 10b5-1(c) conditions suggests the sales followed a pre-planned procedure to mitigate insider trading concerns.
