Context

These are compensation grants under Ardelyx’s Non‑Employee Director Compensation Program (including an election to receive stock instead of cash). Grants and RSUs are common director compensation and do not necessarily signal a buy/sell decision. The derivative award is an option subject to a standard service‑based vesting schedule with an acceleration clause tied to the next annual meeting.
