As little as 7% interest? Sure. Why not.
Yes, even with as little as 7% depending on how widely held the shares are, the rules that the corporation has for appointing directors and whether you have any allies among the significant shareholders. I have shares in a number of companies and have never attended a Board meeting or voted by proxy. I suspect that’s the case with many shareholders. The fewer who participate, the lower the percentage required to exert control.
