Insights

Securities Analyst

TL;DR: Insider reported both a small sale and an RSU settlement, leaving ~27k shares beneficially owned.

The filing shows a contemporaneous sale of 875 shares at $65.77 and an acquisition/settlement of 2,260 shares (Code M) on 08/08/2025, producing reported beneficial ownership figures of 27,260 and 26,385 depending on the line item. The form discloses sizeable outstanding RSU awards convertible into common stock and explicit vesting dates through 2028, which are compensation-related instruments rather than open-market purchases. For investors, these are routine officer compensation and liquidity transactions documented under Section 16.

The filing includes a Power of Attorney signature dated 08/12/2025, satisfying procedural requirements.
