Insights

Financial Analyst

TL;DR: CEO/10% owner made repeated open-market purchases, modestly increasing his direct stake to 665,547 shares.

The reported purchases are small in absolute dollar size per trade but cumulatively increased the reporting person’s direct stake from the prior reported level to 665,547 shares. Transactions occurred at prices ranging from $11.13 to $11.51, reflecting routine open-market accumulation rather than stock-option exercise or derivative activity. For investors, insider purchases can signal management confidence, but these trades should be assessed relative to total share count and company fundamentals, which are not provided in this Form 4.

Corporate Governance Expert

TL;DR: Insider disclosed multiple purchases across personal and retirement accounts, properly reported on Form 4.

The filing documents purchases held both directly and indirectly (Contributory SEP IRA, 401(k), IRA), with a manual signature dated 09/22/2025. The disclosure shows compliance with Section 16 reporting requirements and differentiates direct and indirect ownership. No derivative transactions, dispositions, or plan-based sales are reported. The record is routine from a governance and disclosure perspective.
