Context

• The RSU grant is a typical non-cash compensation award that vests in the future and does not represent immediate, unrestricted ownership.
• The sale was executed under a 10b5-1 plan, which is commonly used to schedule trades in advance and is generally considered routine rather than a real-time signal of the insider’s view.
• No indications in the provided filing that the report was late; it was filed the same day as the sale (June 10, 2026).
