Insights

Securities Analyst

TL;DR: Routine insider sale filing; small lot relative to outstanding shares and shows prior recent sale.

The filing documents a proposed sale of 653 common shares valued at $66,599.47 scheduled for 10/01/2025, and discloses a prior sale of 3,000 shares on 09/02/2025 for $215,160. The shares to be sold were granted as restricted stock on 04/03/2024. Without the filer CIK, issuer name, and total insider holdings, assessing the transaction's relative size versus insider ownership is limited. Based on available figures and the stated outstanding shares count of 107,593,820, the proposed sale is immaterial to total float.

Corporate Governance Expert

TL;DR: Disclosure follows Rule 144 format but key identification fields are incomplete in the supplied content.

The notice follows required structure: broker identification, acquisition method (restricted stock), acquisition date, and planned sale date. However, important identifiers such as the filer CIK/CCC and the issuer's name are not present in the provided text. That omission limits transparency and may require review to confirm the filing is complete and properly attributed.
