Context

• These are earned performance RSUs, not an open-market purchase or exercise of options—meaning they are part of executive compensation tied to performance and tenure rather than a direct cash investment by the insider. Such awards are common for retaining executives and aligning pay with company performance; they do not necessarily signal insider buying or selling intent.
