Key Details

• Price: $0.00 per share at grant (non-cash equity awards).
• Vesting: Both awards vest on the first anniversary of the grant but will be fully vested by the Issuer's 2027 annual stockholder meeting (or immediately upon a Change in Control), subject to the reporting person’s continuous service per the 2024 Equity Incentive Plan.
• Shares owned after the transaction: not specified in the provided excerpt of the filing.
• No 10b5-1, tax-withholding sale, or late-filing notation is indicated in the provided details.

Context

• These are non-cash equity awards (RSUs and a derivative/option-like grant) that give the director a future right to receive common stock if vesting conditions are met; they are typical compensation/retention arrangements and do not reflect an open-market purchase or sale. Vesting accelerates on a Change in Control and is otherwise contingent on continued service through the vesting date.
