Insights

Securities Analyst

TL;DR Insider exercised multiple director options on 09/02/2025, increasing his share exposure while significant holdings remain indirectly held via Kokino clients.

The Form 4 documents exercises of four director stock options on 09/02/2025 (reported with transaction code M) at exercise prices between $4.77 and $5.75 for 6,000 shares each, which increases Mr. Averick's direct/derivative exposure to ASYS equity. Material indirect holdings include 2,250,000 shares held by Kokino Family Clients, disclosed under a Schedule 13D. The filing is routine for insiders exercising options but noteworthy given the sizable indirect stake via investment vehicles managed by Kokino.

Corporate Governance Expert

TL;DR Disclosure aligns with Section 16 reporting; exercises and wide-ranging indirect ownership are properly explained.

The filing clearly discloses the reporting person’s relationship to multiple investment entities and family accounts, and lists restricted stock units and option totals. It explains the indirect ownership through Piton and Kokino structures and potential linkage to incentive allocations. From a governance and compliance perspective the Form 4 appears complete and descriptive, showing both direct derivative activity and substantial indirect holdings that investors can trace to the Schedule 13D.
