Insider Ownership Of PORR

While the precise definition of an insider can be subjective, almost everyone considers board members to be insiders. The company management answer to the board and the latter should represent the interests of shareholders. Notably, sometimes top-level managers are on the board themselves.

Most consider insider ownership a positive because it can indicate the board is well aligned with other shareholders. However, on some occasions too much power is concentrated within this group.

We note our data does not show any board members holding shares, personally. Not all jurisdictions have the same rules around disclosing insider ownership, and it is possible we have missed something, here. So you can click here learn more about the CEO.

General Public Ownership

The general public-- including retail investors -- own 37% stake in the company, and hence can't easily be ignored. This size of ownership, while considerable, may not be enough to change company policy if the decision is not in sync with other large shareholders.

Private Company Ownership

Our data indicates that Private Companies hold 54%, of the company's shares. Private companies may be related parties. Sometimes insiders have an interest in a public company through a holding in a private company, rather than in their own capacity as an individual. While it's hard to draw any broad stroke conclusions, it is worth noting as an area for further research.
