Insights

Corporate Insider Transactions Analyst

TL;DR: Insider proposes sale of RSUs and has executed material sales recently.

The filing shows a proposed sale of 6,421 shares acquired as restricted stock units on 10/01/2025

Prior sales by the same person total 30,538 shares for gross proceeds of $336,546.61 over the past three months, with multiple trades executed under 10b5-1 plans. The immediate dependency is the timing noted as "approximate date of sale" 10/07/2025, and execution will occur via Morgan Stanley Smith Barney LLC.

Watch for the actual execution on 10/07/2025 and any subsequent amendment disclosing a different sale amount or cancellation; continued selling at this scale relative to outstanding shares could be meaningful to supply, though no financial performance metrics are provided here.
