Insights

TL;DR: CEO sold 7,665 TEAM shares via a 10b5-1 plan on 10/07/2025.
The sales were executed under a pre-arranged Rule 10b5-1 plan adopted on 02/20/2025, which provides an affirmative defense for scheduled insider trades. Reported trades were split across multiple executions with weighted-average prices reported and price ranges disclosed for each group.
Dependence on plan timing and structure matters: because the plan date is disclosed, investors can treat these as scheduled disposals rather than opportunistic trades tied to unpublished company news. Monitor subsequent Form 4 filings for additional scheduled trades or plan amendments within the next months.
