• All required fields for the planned sale are provided: number of shares, aggregate market value, approximate sale date, broker name, and shares outstanding.

Negative

Insights

Financial Analyst

TL;DR: Routine insider sell of vested compensation shares; size is immaterial relative to outstanding shares.

The Form 144 documents a planned sale of 10,548 common shares valued at $11,447.74, representing roughly 0.017% of the 62.76 million shares outstanding. The shares were acquired via restricted stock vesting and are being sold through Fidelity Brokerage Services with an approximate sale date of 08/19/2025. This appears to be a compensation-related disposition rather than a large-scale insider liquidation, and no other sales in the prior three months are reported.

Corporate Compliance / Securities Attorney

TL;DR: Filing meets Rule 144 disclosure for a compensatory vesting sale; no material compliance red flags visible in the notice.
