Insights

Securities Analyst

TL;DR: Small, routine insider sale disclosed; limited market impact given outstanding share count and modest aggregate value.

The filing documents a proposed sale of 350 shares valued at $31,829 executed via Morgan Stanley Smith Barney LLC and confirms the shares were restricted stock issued on 06/20/2024. Recent disclosed sales in June and July 2025 total 700 shares with aggregate proceeds shown, indicating ongoing disposition activity by the same filer. Against the issuer's reported outstanding shares of 141,367,218, the transaction size is immaterial to capitalization but is relevant for transparency and insider transaction tracking.

Corporate Governance Expert

TL;DR: The Form 144 meets disclosure requirements and includes the Rule 144 representation; procedural compliance is evident.

The notice provides required details: broker name and address, acquisition date and nature (restricted stock from issuer), approximate sale date, and recent sales history. The filer signs the standard attestation about lack of undisclosed material information and references Rule 10b5-1 considerations. This level of disclosure supports governance transparency though it does not itself indicate any governance change.
