Positive

• Transaction properly disclosed on Form 144 with broker and acquisition details
• Acquisitions were vested RSUs (dates: 10/17/2023 and 09/22/2024), indicating earned compensation rather than new purchases
• Sale size is very small relative to outstanding shares (10,000 vs 1,154,840,742)

Negative

• Recent insider selling was disclosed: 10,972 shares sold on 09/16/2025
• Proceeds per prior sale appear low ($17,445.00 for 10,972 shares), which may reflect low execution prices or reporting of gross proceeds only

Insights

Insider Compliance Specialist

TL;DR: Filing documents a routine insider sale under Rule 144, with prior recent sales disclosed.

The notice reports a proposed sale of 10,000 common shares via RBC Capital Markets on 10/10/2025 and discloses acquisition dates via RSU vesting on 10/17/2023 and 09/22/2024. The form includes the required representation about material nonpublic information and mentions trading-plan considerations.

Key compliance points: the sale is being reported on a Form 144 with broker details and outstanding shares stated, and a prior sale on 09/16/2025 is disclosed. Monitor settlement and public disclosures to confirm timing aligns with the proposed sale date.

Equity Impact Analyst

TL;DR: The sale size is immaterial to total share count but shows insider liquidity activity.

The proposed 10,000-share sale has an aggregate market value of $38,000.00 against 1,154,840,742 shares outstanding, and follows a recent sale of 10,972 shares on 09/16/2025. These figures indicate limited direct market impact given the large outstanding base.

Dependencies include actual execution on 10/10/2025 and any press or filings around that date. Investors often note repeated insider sales for context; however, the absolute sizes disclosed here are small versus total shares outstanding.
