Insights

Financial Analyst

TL;DR: Insider purchased 3,671.4 AVA shares at $35.55, resulting in 9,988.85 shares beneficially owned (indirect).

The purchase of 3,671.4 shares at $35.55 is a routine insider acquisition and increases the reporting person’s indirect stake to 9,988.85 shares, held in a 401(k) plan. The filing also shows a separate disposal of 8,812 shares; the form does not provide context or dates for that disposal beyond the table entries. For investors, these are typical Section 16 disclosures and do not by themselves indicate a material corporate change.

Corporate Governance Expert

TL;DR: Form 4 discloses an officer-level purchase and an indicated disposal; both appear to be routine plan-related transactions.

The report identifies Bryan A. Cox as Senior Vice President and shows an acquisition executed under code P, with indirect ownership via a 401(k) plan. The combination of an acquisition and a listed disposal suggests plan mechanics (e.g., reallocations or plan trades) rather than strategic insider signals. The filing is properly signed and dated 09/17/2025, consistent with timely reporting requirements.
