Insights

Securities Analyst

TL;DR: Significant insider purchases increased beneficial holdings to 178,205 shares, all held indirectly through a controlled entity.

The reporting shows concentrated open-market purchases executed in late July and mid-August 2025, cumulatively raising Giustra's beneficial ownership to 178,205 shares. Transaction prices ranged from $3.90 to $4.72, indicating material capital deployed by an insider and suggesting confidence or a strategic accumulation. The ownership is indirect via Sestini & Co., which affects how control and voting might be exercised. No options, warrants or other derivatives are disclosed, so reported exposure is equity-only.

Corporate Governance Expert

TL;DR: Director disclosed indirect ownership structure and multiple purchases; form is complete regarding reported non-derivative transactions.

The filing cleanly discloses the relationship (Director and 10% owner) and specifies that the shares are held by an entity controlled by the reporting person, satisfying Section 16 transparency on beneficial ownership. Multiple small transactions are aggregated and reported on separate lines, culminating in a single cumulative total. The absence of amendments or derivative holdings simplifies the ownership picture.
