Co-investment agreements are increasingly popular in the private equity world, allowing investors to invest directly alongside a fund in specific deals. These agreements offer institutional investors, such as pension funds or family offices, an opportunity to participate in high-value deals without having to commit capital to the entire fund. For private equity firms, co-investments help spread risks and secure additional capital for large acquisitions. In this article, we explain how co-investment agreements work, their structure, and the benefits and risks they present for both private equity firms and investors.

What Is a Co-Investment Agreement?

A co-investment agreement is a legal arrangement between a private equity fund and one or more investors, allowing those investors to contribute capital to a specific deal. The investors, known as co-investors, invest directly in a portfolio company alongside the main fund, usually on the same terms. Unlike standard limited partners (LPs), co-investors participate only in the selected deals covered by the agreement rather than in the entire fund.

How Co-Investments Work

Co-investments are typically offered to existing LPs of the fund, although other institutional investors may also participate. Here’s how a typical co-investment works:

  1. The private equity fund identifies a large or strategic investment opportunity that requires additional capital beyond the fund’s capacity.
  2. The fund offers a co-investment opportunity to select investors, providing them with a co-investment agreement detailing the terms and conditions.
  3. Co-investors contribute capital to the specific deal, usually on the same financial terms as the main fund, without paying management fees or carried interest.
  4. The co-investors and the main fund share profits and risks proportionally based on their investment contributions.

Key Elements of a Co-Investment Agreement

A co-investment agreement outlines the specific terms governing the investment. Key elements include:

  • Investment Amount: The total capital to be contributed by each co-investor.
  • Governance Rights: Co-investors may have limited governance rights, typically focused on major decisions affecting the portfolio company.
  • Profit Distribution: The agreement specifies how profits will be distributed between the fund and the co-investors.
  • Exit Strategy: Terms defining how the co-investment will be exited, including rights to participate in sales or IPOs.
  • Liability and Risk Allocation: Co-investors usually enjoy limited liability, similar to LPs in the main fund.

Benefits of Co-Investment Agreements

Co-investment agreements offer several advantages for both private equity firms and investors:

  • For Private Equity Firms:
    • Access to additional capital for large acquisitions or strategic investments.
    • Risk sharing by spreading exposure across more investors.
    • Deepening relationships with key institutional investors.
  • For Investors:
    • Opportunity to invest in high-quality deals without paying management fees or carried interest.
    • Greater control over capital deployment, focusing only on selected deals.
    • Access to exclusive private equity opportunities alongside experienced fund managers.

Risks Associated with Co-Investments

While co-investment agreements offer several benefits, they also come with risks:

  • Concentration Risk: Co-investors may have limited diversification, as they are exposed to only one or a few deals.
  • Lack of Control: Co-investors often have limited governance rights, relying on the fund’s management team for key decisions.
  • Exit Uncertainty: Co-investors must align their exit strategy with the main fund, which can complicate liquidity planning.
  • Complex Legal Agreements: Co-investment agreements require careful legal review to ensure that rights and obligations are clearly defined.

When to Use a Co-Investment Agreement

Co-investment agreements are best suited for large, strategic investments where the private equity fund needs additional capital. These agreements are also common in buy-and-build strategies, where multiple acquisitions are required to build a larger business. Institutional investors looking for exposure to private equity without committing to an entire fund also find co-investments attractive.

Conclusion

Co-investment agreements are a valuable tool for both private equity firms and investors. They allow private equity funds to access additional capital while offering investors the chance to participate in high-value deals on favorable terms. However, co-investments come with risks, including concentration risk and exit uncertainty, which require careful management. For investors and fund managers alike, understanding the terms and structure of co-investment agreements is essential for maximizing returns and minimizing risks.
