Insights

Financial Analyst

Insider purchased 2,000 AVBC shares; modest size, limited market impact.

The filing shows a direct acquisition of 2,000 shares at $14.49 on 08/08/2025, bringing direct beneficial ownership to 10,000 shares and an additional 100 shares held indirectly via an LLC.

Corporate Governance Expert

Form 4 disclosure is standard; transaction details are clearly reported.

The report identifies the reporting person as an officer and director and records the transaction with transaction code 'P'. Ownership is broken out into direct and indirect holdings which supports transparency for Section 16 reporting. The size of the acquisition is small relative to what would typically be considered material.
