Private Equity
Quick Definition
Private equity (PE) is ownership or interest in companies that are not publicly traded on a stock exchange. PE firms raise capital from institutional investors and high-net-worth individuals, use it to acquire or invest in private companies, improve operations, and eventually exit (through IPO or sale) to generate returns, typically over a 5 to 10 year investment horizon.
What It Means
Private equity represents the largest segment of the alternative investment universe. According to Ocorian's Global Asset Monitor, global private equity fund assets reached a record $10.6 trillion at the end of 2025, growing 17.8% in a single year. Preqin and iCapital data show AUM is on track to surpass $10 trillion in closed-end funds alone, with forecasts reaching $17.4 trillion by 2030.
Unlike public market investing where you can buy and sell stocks daily, private equity locks up capital for years. In exchange for that illiquidity, PE has historically delivered higher returns than public markets, though the premium has narrowed in recent years as the industry has scaled.
The PE industry traces its modern origins to the leveraged buyout (LBO) boom of the 1980s, pioneered by firms like KKR, Forstmann Little, and Clayton Dubilier & Rice. Today the industry encompasses buyouts, growth equity, venture capital, real estate, infrastructure, and credit strategies.
Private Equity Strategies
| Strategy | What It Does | Target Companies | Typical Hold Period |
|---|---|---|---|
| Leveraged Buyout (LBO) | Acquires established companies using significant debt financing | Mature, cash-flow-positive businesses | 4-7 years |
| Growth Equity | Minority investment in growing companies that need capital | High-growth, pre-IPO companies | 3-5 years |
| Venture Capital | Early-stage investment in startups | Seed to pre-IPO stage | 7-10 years |
| Distressed/Turnaround | Buys struggling companies at discount to improve | Operationally or financially distressed | 3-7 years |
| Buyout (Management Buyout / MBO) | Management acquires company from current owner | Divisions, family businesses | 4-7 years |
| Real Assets (PE) | Infrastructure, real estate, natural resources | Long-life assets | 7-15+ years |
The LBO Model: How Buyouts Work
The leveraged buyout is the signature PE strategy. Here is the mechanics:
- PE firm identifies a target: A stable, cash-generative business with defensible market position
- Acquisition financing: Typically 30-40% equity from the PE fund + 60-70% debt (bank loans, high-yield bonds)
- Value creation: Over 5-7 years, improve operations, grow revenues, reduce costs, pay down debt
- Exit: Sell to a strategic acquirer, another PE firm, or take the company public via IPO
- Returns: Distributed to limited partners (investors) minus carried interest (PE firm's profit share)
Example LBO economics:
| Item | Value |
|---|---|
| Acquisition price | $500M (10x EBITDA of $50M) |
| Equity contributed | $150M (30%) |
| Debt raised | $350M (70%) |
| Hold period | 6 years |
| EBITDA at exit | $80M (grew from $50M) |
| Exit multiple | 12x EBITDA |
| Exit enterprise value | $960M |
| Debt repaid | $200M (from cash flows) |
| Remaining debt | $150M |
| Equity value at exit | $960M - $150M = $810M |
| Return on $150M equity | 5.4x (29% IRR) |
The debt amplifies returns: the equity investment grew 5.4x while the total enterprise value grew only 1.9x. This is the power (and risk) of leverage.
PE Fee Structure: "2 and 20" Plus Carry
| Fee | Description |
|---|---|
| Management fee | 1.5-2% annually on committed capital; covers fund operating costs |
| Carried interest ("carry") | 20% of profits above the hurdle rate; performance incentive |
| Preferred return (hurdle rate) | Typically 8%; LPs receive first 8% of returns, carry only kicks in above this |
Waterfall example: LP invests $10M, 8% preferred return, 20% carry:
- 8% hurdle on $10M over 5 years = $4.69M preferred return
- Total fund return: $25M (before carry)
- LP receives: $14.69M first (return of capital + preferred return)
- Remaining $10.31M: 80% to LP ($8.25M) + 20% carry to GP ($2.06M)
- Total LP return: $22.94M on $10M = 2.3x, 18.1% IRR
PE Returns: Historical Evidence
| Period | U.S. PE Buyout Net IRR | S&P 500 Return | Outperformance |
|---|---|---|---|
| 2000-2010 | ~10-12% | ~1% | Significant |
| 2010-2020 | ~14-16% | ~14% | Modest |
| 2000-2020 (full cycle) | ~12-14% | ~7% | ~5-7% |
| 2020-2025 | ~12-15% | ~10-12% | Narrowing |
The illiquidity premium, the extra return PE earns over public markets, is estimated at 3-5% annually over long periods. However, recent academic studies debate whether this holds after accounting for leverage and survivorship bias. As the industry has grown to over $10 trillion in AUM, the premium has compressed, and manager selection has become increasingly important.
KPMG's Q1 2026 Pulse of Private Equity report notes that global PE company inventory remains at record highs, with exit activity still below historical norms. This "dry powder" overhang means many funds are holding investments longer than their target hold periods, which pressures IRRs and complicates fundraising for new vintages.
Access to Private Equity
Historically limited to institutions and ultra-high-net-worth individuals:
| Vehicle | Minimum | Who Can Access |
|---|---|---|
| Direct PE fund | $5-25M | Institutional; UHNW |
| Fund of PE funds | $250K-$1M | High-net-worth |
| Semi-liquid PE vehicles (BDCs, interval funds) | $10,000-$25,000 | Accredited investors |
| Publicly traded PE firms (KKR, Blackstone, Apollo) | Any amount (stock) | All investors |
| Private equity ETFs | Any amount | All investors |
Publicly traded PE firms (KKR, Blackstone, Apollo Global Management, Carlyle Group) allow retail investors to participate in PE economics through owning stock of the manager, though this is different from being a direct limited partner in a PE fund.

The top 10 PE firms manage more than $5.5 trillion in combined AUM as of Q1 2026, according to Dealroom data sourced from SEC filings.
The Rise of Private Credit
Private credit has emerged as one of the fastest-growing segments within private markets. BlackRock estimates global private credit AUM at $2.2 trillion as of March 2025, with forecasts reaching $4.5 trillion by year-end 2030. Moody's 2026 Outlook projects AUM surpassing $2 trillion in 2026, driven by asset-backed finance and direct lending.
Direct lending, the largest private credit strategy, represents roughly 54% of global AUM. The shift from traditional bank lending to private credit funds has accelerated as banks pull back from middle-market lending, creating opportunities for PE-affiliated credit funds (Apollo, Ares, Blackstone Credit).
Key Points to Remember
- PE invests in private (non-publicly traded) companies through buyouts, growth equity, and venture capital
- Global PE AUM reached $10.6 trillion in 2025, forecast to hit $17.4 trillion by 2030 (Ocorian)
- LBOs use debt to amplify equity returns; 5-7 year hold periods target 2-4x equity multiples
- PE charges management fees + carried interest; total costs are high
- Historical PE returns have exceeded public markets by approximately 3-5% annually (the illiquidity premium), though the gap is narrowing
- Capital is locked up for 5-10 years; illiquidity is the cost of the premium return
- Retail investors can access PE economics through publicly traded PE firm stocks or semi-liquid vehicles
- Private credit, the fastest-growing PE-adjacent segment, has surpassed $2.2 trillion in AUM
Common Mistakes to Avoid
- Expecting public market liquidity: PE capital is committed for years. Forced exits are costly or impossible. KPMG's Q1 2026 report shows many funds are holding investments longer than target due to slow exit markets, which can tie up capital for 7-10+ years.
- Ignoring the fee impact: Carried interest at 20% of profits and management fees of 1.5-2% annually meaningfully reduce net returns. On a fund that returns 15% gross, fees can bring net returns to 10-11%.
- Extrapolating top-quartile returns to all PE: The difference between top and bottom quartile PE returns is enormous. Manager selection matters more in PE than in public markets. Bottom-quartile funds may not even return capital, while top-quartile funds can generate 3-5x multiples.
- Underestimating the impact of rising interest rates on LBO returns: Higher borrowing costs reduce the debt capacity of LBOs, requiring more equity and reducing returns. The 2022-2024 rate hiking cycle made leveraged buyouts more expensive and harder to justify, though conditions have eased modestly in 2025-2026.
Frequently Asked Questions
Q: What is the difference between private equity and venture capital? A: Both are forms of private equity broadly, but venture capital focuses on early-stage startups (seed through pre-IPO) with binary outcomes (most fail; winners return 10-100x). Traditional PE (buyouts) focuses on mature, cash-flowing businesses with more predictable outcomes and heavy use of debt financing.
Q: Can regular investors access private equity? A: Increasingly yes. Business Development Companies (BDCs) listed on exchanges, closed-end PE funds, and semi-liquid interval funds provide retail access. The minimum investments are lower but the fee structures remain high. Owning stock in publicly traded PE managers (KKR, Blackstone) is another route.
Q: How does PE "create value" in portfolio companies? A: Through a combination of: (1) operational improvements (better management, cost cutting, new strategies), (2) revenue growth (bolt-on acquisitions, new markets), (3) multiple expansion (buying at 8x and selling at 12x EBITDA if conditions allow), and (4) debt paydown (increasing equity value as leverage is reduced).
Q: Why has private credit grown so fast? A: Banks have pulled back from middle-market lending due to regulatory pressure since the 2008 financial crisis. Private credit funds, affiliated with PE firms like Apollo, Ares, and Blackstone, stepped in to fill the gap. The asset class offers floating-rate yields that appeal to investors in a higher-rate environment, and borrowers get faster, more flexible financing than banks provide. BlackRock forecasts private credit AUM reaching $4.5 trillion by 2030.
