If Maria knew that Mark had her company in the palm of his hand, then she wouldn't dare to step out of line. Since Maria didn't have anything incriminating on Mark, she couldn't do anything to get him arrested, so she would be caught in a dilemma. If she exposes Arit and Arit is arrested, then Mark will only need to push a button for her family company to go down, and she will be on the street in less than a week.
Mark didn't have any need for Triston Transportation, so most of the shareholders in his company would see this as a frivolous and bad investment, but he would deal with that when the time came.
