Insights

Financial Analyst

TL;DR: Director sold 44,000 TEM shares at $69.90; remaining holdings split between an indirect trust position and a direct holding.

This Form 4 documents a straightforward open-market disposition by a director rather than an option exercise or derivative transaction. The sale reduces the reporting person\'s direct economic exposure by 44,000 shares while leaving an indirect holding of 86,756 shares in a revocable trust and a direct holding of 15,511 shares. The explanation clarifies that some share counts changed due to pro rata distributions from an investment vehicle, not a cash transaction. For investors, this is a routine disclosure of insider selling activity with no additional financial metrics provided.
