Insights

Corporate Governance Expert

Routine insider resale notice tied to RSU vesting; limited investor impact.

The filing records a proposed sale of 7,771 shares after the vesting of restricted stock units on 02/19/2026. It names Morgan Stanley Smith Barney LLC as the listed broker and attributes the shares to services rendered.

Because this is a Form 144 resale notice for vested awards, the excerpt shows a mechanical post-vesting transaction; timing and proceeds are governed by subsequent broker execution and holder decisions, and the filing does not disclose cash-flow recipients or sale timing.
