Insights

Corporate Governance Specialist

Initial insider holding shows executive equity alignment with ATAI.

The Form 3 documents that Ryan Barrett directly owns 155,066 common shares and holds multiple stock options totaling 2,918,711 underlying shares across nine grants, with exercise prices from $1.18 to $15.00.

This disclosure identifies Barrett as a company officer and confirms standard Section 16 reporting; the mix of shares and long‑dated options is typical for senior executives and shows potential future dilution if exercised.

Compensation & Equity Analyst

Option vesting schedules indicate staged compensation over multi‑year periods.

The filing details vesting patterns: several grants vested 25% on specified dates (e.g., 01/01/2023, 09/01/2023, 03/14/2024, 01/01/2025) with remaining shares vesting monthly over 36 months, and one grant scheduled to begin vesting on 01/01/2026.

These schedules clarify when shares may become exercisable and potentially impact share count if exercised; no cash values or realization events are disclosed.
