Insights

Insider Transactions Analyst

Insider plans a cash sale of vested option shares worth $4.42M on 10/06/2025.

The filing discloses a planned disposition of 21,368 common shares acquired via an option granted 04/09/2018, with $4,421,912.42 shown as the aggregate market value and sale routed through Fidelity Brokerage Services LLC. The table notes the sale is to be paid in cash.

Recorded prior dispositions by James A. Burke on multiple dates in September 2025 and October 2025 indicate ongoing sell activity by the same individual; monitor reported sale dates and volumes over the next days for completion details.

Market Impact Analyst

Transaction size is disclosed but represents a small portion of the issuer's outstanding shares.

The filing shows 338,820,324 shares outstanding alongside the proposed sale, which frames the disclosed $4,421,912.42 transaction in context of market scale. Execution through a major broker (Fidelity) suggests standard market-channel selling.

Because multiple prior sales by the same person are listed with specific gross proceeds on sequential dates in September 2025 and October 2025, short-term trading volumes in the issuer's shares are a near-term item to check against daily market liquidity.
