Key Details

Reported prices shown are weighted averages; the filing notes the shares were sold in multiple transactions at varying prices (ranges disclosed in the filing).
Sales were made pursuant to a 10b5-1 trading plan adopted by Madden on December 15, 2025.
Shares owned after the transactions: not specified in the provided filing excerpt.

Context

These were sales executed under a pre-established 10b5-1 plan, which allows insiders to sell according to a preset schedule and is generally considered a routine compliance mechanism; it does not by itself indicate current insider sentiment.
The filing discloses weighted-average prices and provides that the reporting person will supply a per-price breakdown upon request to the issuer, shareholders, or the SEC staff.
