Insights

Financial Analyst

TL;DR: Director sale of 1,500 MGRC shares at $118.499; change appears routine and not material to valuation.

The filing documents a single non-derivative sale by a director on 08/06/2025 for 1,500 shares at $118.499 per share and shows 7,000 shares owned following the trade.
