TL;DR: CEO exercised 84,612 options at $13 and sold 84,612 shares at $48.4408, leaving 565,036 shares beneficially owned.

The report documents a common insider sequence: an option exercise at a $13 strike followed by a sale at $48.4408. The transaction reduced direct beneficial ownership to 565,036 shares while leaving disclosed indirect holdings in a spouse account and the company's 401(k). The filing includes standard split adjustments and a multi-year vesting schedule for the option. For disclosure purposes, the size of the transaction and the post-transaction ownership level are the primary quantifiable facts investors can use to update insider-holding records.
