Insights

Securities Analyst

TL;DR: A company director executed sizeable open-market sales totaling 135,000 VRT shares, disclosed on Form 4.

The filing documents a 08/26/2025 sale of 100,000 Class A shares with a weighted average price of $128.2211 (range $128.00–$128.39) and an additional 35,000‑share disposal the same day.

The report identifies Steven Reinemund as a director who sold shares and still holds 133,333 shares indirectly. The Form 4 includes a footnote offering to supply granular trade-price breakdowns on request, which supports transparency.
