Co-Investments: Control, Cost Efficiency, and Hidden Complexity

Co-investments have become one of the most sought-after avenues in private markets. For many investors, they offer a compelling proposition: direct exposure to high-quality deals alongside experienced sponsors, often with reduced fees and greater control over capital deployment.

On the surface, the appeal is clear. But beneath this attractiveness lies a more nuanced reality. Co-investments are not simply a more efficient way to invest. They introduce a distinct set of trade-offs that require careful evaluation.

Why Co-Investments Are Gaining Momentum

The growth of co-investments has been driven by both General Partners and Limited Partners.

For GPs, co-investments provide a way to syndicate larger deals without over-concentrating their main fund. For LPs, they offer the opportunity to increase exposure to specific assets they have conviction in.

According to industry data from Preqin, co-investments now account for a significant and growing share of private equity allocations, with many institutional investors targeting 10 to 20 percent of their private market portfolios through co-investment strategies.

This shift reflects a broader trend toward greater selectivity and control in capital deployment.

The Case for Co-Investments

Co-investments offer several structural advantages that make them attractive.

First, there is cost efficiency. Co-investments are often offered with reduced or no management fees and carried interest, which can meaningfully enhance net returns. In an asset class where fees can significantly impact outcomes, this is a powerful benefit.

Second, co-investments provide greater control and transparency. Investors have visibility into specific assets, allowing for more informed decision-making compared to blind pool commitments.

Third, they enable targeted exposure. Instead of allocating capital across an entire fund, investors can selectively back deals that align with their strategy and risk appetite.

Data from McKinsey & Company suggests that well-executed co-investment programs have, in many cases, delivered higher net returns than traditional fund investments, largely due to fee savings and selective participation.

The Illusion of Simplicity

Despite these advantages, co-investments can create an illusion of simplicity.

Because they are typically presented alongside a lead GP, investors may assume that the heavy lifting has already been done. However, co-investments require independent underwriting, often within compressed timelines.

Unlike primary fund commitments, where diligence is focused on the manager, co-investments demand deal-level evaluation. This includes assessing:

  • The quality of the underlying asset
  • Entry valuation and capital structure
  • Sector dynamics and growth assumptions
  • Downside risks and exit scenarios

In many cases, investors are expected to make decisions within weeks, or even days. This speed can compromise the depth of analysis if not supported by robust internal capabilities.

The Challenge of Adverse Selection

One of the most discussed risks in co-investing is adverse selection.

Not all deals are equally shared. GPs may offer co-investment opportunities selectively, sometimes retaining the most attractive deals within the fund while syndicating others.

While this is not always the case, it introduces an inherent asymmetry. Investors must be able to distinguish between opportunities that are genuinely attractive and those that are being distributed for balance sheet or concentration reasons.

Research from Bain & Company highlights that access alone does not guarantee performance. The ability to filter and underwrite effectively is what ultimately drives outcomes in co-investments.

Operational and Monitoring Complexity

Co-investments also introduce operational challenges.

Each deal requires:

  • Separate due diligence processes
  • Legal structuring and documentation
  • Ongoing monitoring and reporting

As portfolios scale, this can lead to increased complexity, particularly for investors managing multiple co-investments across sectors and geographies.

Unlike fund investments, where monitoring is delegated to the GP, co-investments demand a more active role. This includes tracking performance, engaging with sponsors, and responding to changes in the underlying business.

Without the right infrastructure, this complexity can dilute the intended benefits of co-investing.

Concentration Risk and Portfolio Impact

Co-investments tend to be larger, more concentrated exposures. While this can enhance returns, it also increases portfolio risk.

A single underperforming co-investment can have a disproportionate impact, particularly if position sizing is not managed carefully.

This makes portfolio construction critical. Co-investments must be integrated into a broader strategy that balances concentration with diversification.

When Co-Investments Work Best

Co-investments are most effective when investors have:

  • Strong internal underwriting capabilities
  • The ability to move quickly without compromising diligence
  • Clear portfolio construction frameworks
  • Established relationships with high-quality GPs

In such cases, co-investments can serve as a powerful tool to enhance returns, improve capital efficiency, and gain deeper exposure to select opportunities.

Conclusion

Co-investments offer a compelling combination of control, cost efficiency, and access to high-quality deals. It is easy to see why they have become a central part of private market strategies.

However, they are not without complexity. The very features that make them attractive also introduce new risks, from compressed decision timelines to adverse selection and operational demands.

For investors, the key is to approach co-investments with the same rigor as primary investments. Access is only the starting point. Discipline, selectivity, and execution ultimately determine success.

In private markets, co-investments can be a powerful advantage. But only when their trade-offs are fully understood and actively managed.
