Positive

Insights

Corporate Governance Analyst

TL;DR: Large, repeated insider sales were disclosed; transactions were processed through a broker and include a Rule 144 notice.

The filing shows a planned sale of 19,596 shares via Fidelity and documents prior open-market sales by the same insider totaling 443,760 shares between 09/10/2025 and 10/07/2025. These entries reflect compliance with public-disclosure rules for insider transactions and use of Rule 144 mechanics for restricted or control securities.

The main dependency for governance assessment is the proportion of insider sales to outstanding shares: the disclosed 443,760 shares represent about 0.13% of the reported 338,820,324 shares outstanding. Watch confirmations that each sale matches the listed broker records and that the attestation about material non-public information remains valid at the time of sale.

Securities Compliance Specialist

TL;DR: The Form 144 is structured correctly showing acquisition details and recent transaction history; it includes required attestation language.

The securities to be sold were noted as acquired by an option granted on 04/09/2018, with payment at sale listed as cash, satisfying the acquisition/payment disclosure requirements. The broker, sale dates, share counts, and aggregate market value are provided as required for a Rule 144 notice.

Key compliance items to confirm are the exact match between the planned sale date 10/08/2025 and the broker execution records, and confirmation that any volume or manner-of-sale conditions under company insider policies or 10b5-1 plans (if applicable) are documented with corresponding dates.
