Securities Analyst

TL;DR: Routine Rule 144 notice disclosing a proposed sale of restricted shares; no recent sales reported.

The filing simply documents a proposed sale of 1,671 common shares via Morgan Stanley Smith Barney with a stated aggregate market value of $395,625.96. Acquisition details show these shares resulted from restricted stock vesting on 08/30/2024 and 08/26/2025, which is consistent with compensation-related equity.

From a market-impact perspective the notice is informational; it does not provide pricing, trading plan details, or indicate prior sales in the past three months. Impact is neutral absent further context on insider role or company market capitalization.
