The board remains five members, with CEO Dhrupad Trivedi also serving as chair and Eric Singer as lead independent director. All other directors are deemed independent under NYSE rules, and committees are fully independent with refreshed chair roles.

Executive pay is heavily performance-based, using revenue and adjusted EBITDA for annual bonuses and stock-price-based performance RSUs plus time-based RSUs for long-term incentives.
