Insider Ownership Of Seres Therapeutics

The definition of company insiders can be subjective and does vary between jurisdictions. Our data reflects individual insiders, capturing board members at the very least. Company management run the business, but the CEO will answer to the board, even if he or she is a member of it.

Insider ownership is positive when it signals leadership are thinking like the true owners of the company. However, high insider ownership can also give immense power to a small group within the company. This can be negative in some circumstances.

This compares to a market capitalization of US$123m. We generally like to see a board more invested. However it might be worth checking if those insiders have been buying.

General Public Ownership

The general public, who are usually individual investors, hold a substantial 52% stake in Seres Therapeutics, suggesting it is a fairly popular stock. This level of ownership gives investors from the wider public some power to sway key policy decisions such as board composition, executive compensation, and the dividend payout ratio.

Private Equity Ownership

With a stake of 13%, private equity firms could influence the Seres Therapeutics board. Some investors might be encouraged by this, since private equity are sometimes able to encourage strategies that help the market see the value in the company. Alternatively, those holders might be exiting the investment after taking it public.

Public Company Ownership

Public companies currently own 12% of Seres Therapeutics stock. This may be a strategic interest and the two companies may have related business interests. It could be that they have de-merged. This holding is probably worth investigating further.
