Insights

Financial Analyst

TL;DR: Insider sold 7,665 TEAM shares under a 10b5-1 plan; holdings remain substantial at ~191k shares, suggesting pre-scheduled liquidity rather than ad hoc sales.

The filing shows systematic disposals executed under a Rule 10b5-1 plan adopted on 02/20/2025, with three reported lots on 08/25/2025 at weighted-average prices near $169-$171. Such plans are commonly used by executives to crystallize value while reducing timing risk. The report lists indirect beneficial ownership held by an entity acting as trustee, confirming that the remaining position is held indirectly rather than directly by the reporting person.
