Insights

Financial Analyst

TL;DR: Director-reported share sales in late August 2025 reduced holdings but substantial beneficial ownership remains via affiliated funds.

The Form 4 documents routine open-market or private sales (transaction code S) on 08/22/2025 and 08/25/2025 at prices of $18.0135 and $17.9508. Aggregate dispositions are modest relative to the remaining reported positions, which total hundreds of thousands of shares across Braeside Capital and Braeside Capital II and a direct holding of 42,726 shares. No options or other derivatives are reported. From a financial perspective, these transactions alter short-term insider sell metrics but do not eliminate meaningful ownership that could align manager and shareholder interests.

Corporate Governance Expert

TL;DR: Disclosure follows Section 16 rules and includes standard beneficial ownership disclaimers for manager/co-manager relationships.

The filing properly identifies the reporting person as a director and indicates indirect beneficial ownership through investment vehicles managed by Braeside Investments, LLC, with the usual disclaimer limiting beneficial ownership to pecuniary interest. The Form 4 lists individual sales with quantities, prices, and post-transaction holdings, and includes the reporting signature dated 08/26/2025. There are no amendments or derivative positions disclosed, and the submission appears compliant with required disclosures in the document provided.
