Key Details

• Transaction date: 2026-06-10; Filing date: 2026-06-12 (Form 4 filed timely).
• Grant: 3,017 RSUs; Acquisition price reported: $0.00 (transaction code A = Award/Grant).
• Shares owned after transaction: Not specified/disclosed in the filing.
• Vesting condition (per footnote): RSUs vest upon the earlier of (A) the next annual meeting of stockholders or (B) the one‑year anniversary of June 10, 2026 (service‑based vesting).

Context

• RSUs are a compensation award that convert to actual shares only if vesting conditions are met; they do not represent immediate share sales or purchases. As a 10% owner, this grant reflects equity compensation for a significant shareholder but should not be read as an immediate market signal (no cash outlay and no immediate change in public float until RSUs vest and shares are issued).
