Understanding Co-Investment Structures in Private Markets

Co-investment has become one of the most widely discussed structures within private markets.

For institutional investors, family offices and sophisticated allocators, co-investment provides a way to participate in a specific investment opportunity alongside a lead manager, typically on a deal-by-deal basis, rather than solely through a traditional commingled fund.

A co-investment generally sits alongside a primary fund commitment. The lead manager identifies a transaction that is larger than the fund can accommodate on its own, or where additional capital is desirable, and offers a portion of that transaction to selected investors.

The result is a targeted allocation to a single asset or company, structured through a dedicated vehicle and governed by the terms of that specific opportunity.

Co-investment appeals to institutional investors for several reasons.

It offers direct exposure to specific assets that meet the investor's own conviction, rather than diversified exposure across an entire fund portfolio. It can also strengthen the working relationship with the lead manager and, in many cases, is offered on more efficient fee terms than a primary fund commitment.

For many institutions, co-investment is used as a complementary strategy that sits alongside — not instead of — their broader fund programme.

Because co-investment concentrates capital in a single opportunity, governance matters considerably.

Institutional investors typically review the underlying transaction, the vehicle documentation, the rights attached to their interest and the reporting they will receive throughout the holding period. Independent administrators, legal counsel and, where appropriate, external tax advisers are usually involved.

This heightened focus on due diligence reflects the concentrated nature of a co-investment relative to a diversified fund.

A core principle of co-investment is alignment.

Investors generally expect the lead manager to retain a meaningful position in the same transaction, ensuring that decisions on strategy, hold period and eventual exit are made with shared economic interests.

This alignment is often cited as one of the defining characteristics that distinguishes institutional-quality co-investment programmes.

Co-investment has evolved from an occasional feature of private markets into an established discipline of its own.

For sophisticated investors, it offers a way to build focused exposure to specific opportunities under clearly defined governance and alignment principles — a combination that continues to attract institutional interest across global private markets.
