Private Equity: How Private Equity Firms Invest, Grow, and Exit Companies
A PE firm buys a company for $100M using $30M equity and $70M debt. After 5 years, they grow EBITDA from $10M to $20M and sell at 10x EBITDA for $200M. Repaying $70M debt leaves $130M — a 4.3x return on $30M equity. Here's how private equity works.
Private equity (PE) is an alternative investment class where firms raise capital from institutional investors (pension funds, endowments, insurance companies) and high-net-worth individuals to acquire, improve, and sell companies. PE firms typically take controlling stakes in mature companies, often using significant debt financing (leverage) to fund acquisitions. The goal is to improve operations, accelerate growth, and sell the company at a profit within 3-7 years. The PE industry has grown dramatically: global private equity assets under management exceeded $8 trillion in 2025. Top firms include Blackstone, KKR, Apollo Global Management, Carlyle Group, and CVC Capital Partners. Angel investing: an earlier stage of private company investing →
Real-world example: A PE firm identifies a manufacturing company with $10M EBITDA (earnings before interest, taxes, depreciation, and amortization). They negotiate a purchase price of $100M (10x EBITDA). The firm puts up $30M in equity and borrows $70M from banks (a 70% LBO leverage ratio). Over 5 years, they improve operations, cut costs, and expand into new markets, growing EBITDA to $20M. They sell the company at 10x EBITDA = $200M. After repaying the $70M debt, $130M remains. The $30M equity investment returned $130M — a 4.3x multiple or roughly 34% annualized return. This is the basic LBO math that drives private equity returns.

Buyout Strategies: What PE Firms Look For
PE firms target companies with specific characteristics: strong market position or niche dominance, predictable and recurring cash flows, opportunities for operational improvement, capable management teams (or ability to replace them), potential for growth through acquisitions or geographic expansion, and industries where debt financing is feasible. Common buyout strategies include: platform acquisitions (buying a base company to build upon), add-on acquisitions (buying smaller competitors to roll into the platform), turnaround situations (distressed companies needing operational fixes), and corporate carve-outs (buying a division from a larger corporation). The best PE candidates have high EBITDA margins, low capital expenditure requirements, and defensible competitive positions.
Value Creation: How PE Firms Build Value
PE firms create value through several levers. Operational improvements: cutting costs, improving supply chain efficiency, upgrading technology, and optimizing pricing. Strategic initiatives: entering new markets, launching new products, and making add-on acquisitions. Financial engineering: refinancing debt at lower rates, optimizing capital structure, and using dividend recapitalizations (having the company borrow to pay a dividend to the PE firm). Governance improvements: aligning management incentives through equity ownership, strengthening the board, and implementing better financial controls. Multiple expansion: selling the company at a higher EBITDA multiple than the purchase multiple, often by positioning the company in a more attractive industry segment or achieving scale. Academic research shows operational improvements drive roughly 50-60% of PE returns, with leverage contributing 20-30% and multiple expansion 10-20%.

Fund Structure: How Private Equity Funds Work
Private equity funds are structured as limited partnerships with a 10-year life cycle. The general partner (GP) is the PE firm that manages the fund. Limited partners (LPs) are the investors who commit capital. The fund has a 3-5 year investment period during which the GP identifies and acquires companies, followed by a 5-7 year harvest period when the GP improves and exits investments. LPs make capital commitments but do not contribute all capital upfront — the GP issues "capital calls" as investments are made. Returns are distributed to LPs first, with the GP receiving carried interest (typically 20%) on profits after returning capital to LPs. Most PE funds also charge an annual management fee of 1.5-2% of committed capital. The fund structure creates alignment: GPs earn carried interest only if they generate strong returns for LPs.

Fees and Economics: The 2-and-20 Model
Private equity fees follow the "2-and-20" model: a 2% annual management fee on committed capital and 20% carried interest on profits. However, fee structures have evolved. Management fees on larger funds (over $5B) are often 1.5% or lower. Some funds use a "European waterfall" where the GP receives carried interest on a deal-by-deal basis rather than across the whole fund. Most funds have a hurdle rate (typically 7-8% IRR) that must be achieved before the GP earns carried interest. The GP's carried interest is subject to clawback provisions requiring the GP to return excess carried interest if early gains are offset by later losses. These fees are substantial: on a $1B fund, management fees alone total $150-200M over 10 years. LPs carefully evaluate net returns after all fees when selecting PE funds. The high fee structure is justified by PE's historical return premium over public markets of 2-4% annually. Comparing fee structures across investment vehicles →
How can individual investors access private equity?
Individual investors historically had limited access to PE, but options have expanded. Accredited investors (net worth over $1M excluding primary residence, or income over $200K/$300K joint) can invest through: PE funds-of-funds (diversified across multiple PE funds), interval funds and tender offer funds that offer periodic liquidity, business development companies (BDCs) that are publicly traded and invest in private companies, Evergreen PE funds that accept ongoing capital commitments, and crowdfunding platforms like EquityZen and Forge Global for secondary PE interests. The minimum investments for direct PE funds ($500K-$5M) are prohibitive for most individuals, but newer vehicles have lowered minimums to $25K-100K. PE investments should be limited to 10-20% of a portfolio due to their illiquidity and risk. Passive income alternatives including private equity exposure →
What are the risks of private equity investing?
Private equity carries significant risks. Illiquidity is the most important: capital is locked up for 7-10+ years with no ability to sell. There is no secondary market for most PE fund interests. Leverage risk: PE funds use substantial debt, magnifying losses when investments perform poorly. Blind pool risk: investors commit capital before knowing which companies will be acquired. Manager selection risk: returns vary dramatically between top-quartile and bottom-quartile funds — choosing the wrong manager can mean losses instead of 15%+ IRRs. J-curve effect: returns are negative in early years as management fees and deal costs accumulate before investments generate returns. Concentration risk: even diversified PE funds hold only 10-30 companies. These risks make PE unsuitable for most investors, but appropriate for sophisticated investors with long time horizons and the ability to select top-tier managers.

How does private equity compare to venture capital?
Private equity and venture capital are both forms of private investing but differ significantly. PE invests in mature companies with proven business models and positive cash flows, using leverage to enhance returns. VC invests in early-stage companies with no profits or even no revenue, betting on growth potential. PE targets 20-30% IRR with lower failure rates (5-10% of investments fail completely). VC targets 30-50%+ IRR with high failure rates (50-70% of investments fail). PE hold periods are 3-7 years; VC hold periods are 5-10 years. PE typically acquires controlling stakes (50%+ ownership); VC typically takes minority stakes (10-30%). Both are illiquid and use the 2-and-20 fee model, but VC has much wider return dispersion. Some large firms like Blackstone and KKR operate both PE and VC strategies. Angel investing and venture capital: early-stage private investing →
What is the typical holding period for a PE investment?
The typical holding period for a PE portfolio company is 4-7 years. Shorter holds (2-3 years) are possible when a "quick fix" opportunity arises or when market conditions create an attractive exit. Longer holds (7-10+ years) occur when value creation takes longer than expected or market conditions are unfavorable for exits. PE firms typically aim to exit through one of three routes: selling to a strategic buyer (another company in the same industry), selling to another PE firm (a secondary buyout), or taking the company public through an IPO. The exit strategy is often considered at the time of acquisition, though it may change based on market conditions. The 2021-2022 period saw many PE firms holding investments longer than planned as IPO markets slowed and valuation uncertainty increased.
