Pre‑planned 10b5-1 CFO sale; routine, neutral signal.

The CFO sold 8,035 shares at $115 on 10/09/2025 under a pre‑established Rule 10b5‑1 plan dated 6/6/2025, indicating a scheduled disposition rather than an opportunistic trade.

After the transaction, direct beneficial ownership stands at 129,618 shares. The filing notes that a portion comprises RSUs, which each convert into one share upon vesting, linking future share delivery to service or vesting terms.

This is an administrative disclosure of insider activity and does not involve company proceeds. Actual impact depends on ongoing vesting and any future plan‑scheduled trades disclosed in subsequent filings.
