Insights

Securities Analyst

TL;DR Insider filing documents routine sale of vested RSUs and recent 10b5-1 activity, increasing public float modestly.

The filing discloses a proposed sale of 2,100 common shares valued at $55,230 and confirms these shares originated from Restricted Stock Units granted and delivered on 06/03/2024. The record of four prior sales in the last three months totaling 7,833 shares and $201,808.15 in gross proceeds indicates ongoing disposition activity by the same individual, including trades executed under 10b5-1 plans. For investors, this is a transparent compliance disclosure rather than new operational information; it quantifies insider liquidity events that may slightly increase available float.
