What is a Portfolio Company?

A portfolio company is a company (public or private) that a venture capital firm, buyout firm, or holding company owns equity. In other words, companies that private equity firms hold an interest in are considered portfolio companies. Investing in a portfolio company aims to increase its value and earn a return on investment through a sale.

The Private Equity Structure

Private Equity Structure - Diagram

Creating a private equity fund, which invests in companies, requires two different parties: (1) a financial sponsor, and (2) investors.

1. Financial Sponsor

The financial sponsor is generally called the general partner. The financial sponsor manages the private equity fund and receives management fees and carried interest as compensation. Management fees are fees tied to the capital raised, while carried interest is a share of the fund’s profits.

2. Investors

The investors provide the capital required for the fund to invest in companies. Investors include high net worth individuals, family offices, endowments, insurance companies, pension funds, foundations, funds-of-funds, sovereign wealth funds, etc. Investors generate a return from their investment through the private equity fund selling portfolio companies at a higher price than the initial investment cost.

Approaches to Investing in Portfolio Companies

There are numerous methods of investing in a portfolio company. Below, we outline three common methods.

1. Leveraged Buyout (LBO)

A leveraged buyout (LBO) is extremely common in private equity transactions. An LBO involves using primarily debt (hence “leveraged” buyout) and a small equity injection to finance the company’s buyout. The debt is typically raised through using the portfolio company’s assets as security.

2. Venture Capital

Venture capital refers to the provision of capital by private equity funds to start-up companies that require early-stage funding in exchange for an equity stake.

3. Growth Capital

Growth capital refers to providing capital to established businesses to help expand business operations. The capital can be used to help a business develop a new product, restructure operations, finance an acquisition, or expand into new markets.

Common Types of Exits for Portfolio Companies

Investors in private equity funds generate a return through portfolio companies’ exit in the private equity fund. Private equity firms typically acquire companies for a specific period (usually five to seven years), with the end goal of exiting the investment through a sale above the initial investment price. Common exit strategies include the following:

1. Initial Public Offering (IPO)

An initial public offering of a portfolio company generally provides one of the highest valuations, compared to other exits, provided that public market conditions are stable and that there is strong demand. A key disadvantage with an IPO exit is the high transaction costs and potential restrictions placed on existing investors, such as a lock-up period requirement.

2. Strategic Sale

A strategic sale, also called a trade sale, is the sale of a portfolio company to a strategic buyer that can realize material synergies or achieve a strategic fit through the acquisition. Strategic buyers often pay a premium for the portfolio company due to the preceding sentence’s reasons.

3. Secondary Buyout

A secondary buyout is the sale of a portfolio company to another private equity firm. There may be many reasons to engage in a secondary buyout, such as the desire to get rid of the portfolio company or the portfolio company’s management wanting to find another private equity firm to operate with.
