Private equity firm

The history of private equity firms has occurred through a series of boom-and-bust cycles since the middle of the 20th century with significant growth since the 1980s. Private equity firms provided large early investments in several successful start-up companies such as Microsoft, Dell, and Genentech. ==Business model==

Private equity companies, acting as general partners with investors as limited partners, acquire a controlling or substantial minority position in a company and then look to maximize the value of that investment. Strategies include leveraged buyout (with borrowed capital), venture capital (for start ups), and growth capital (mature companies). Private equity firms generally receive a return on investment through one of the following avenues: • an initial public offering (IPO) — shares of the company are offered to the public, typically providing a partial immediate realization to the financial sponsor as well as a public market into which it can later sell additional shares; • a periodic management fee as well as a share of the profits earned (carried interest) from a private-equity fund managed; • a recapitalization — cash is distributed to the shareholders (in this case the financial sponsor) and its private-equity funds either from cash flow generated by the company or through raising debt or other securities to fund the distribution; • a merger or acquisition — the company is sold for either cash or shares in another company. ==Effects==

Concerns have been raised regarding the financial health of private equity-backed companies. The Bank of England issued a warning in 2024, stating that businesses owned by private equity firms were more vulnerable to default than other large businesses. The central bank's research found that more than 2 million people in the UK were employed by firms engaged with private equity and that these companies were responsible for 15% of all corporate debt. A report the same year by Moody's Ratings found that globally, companies backed by the twelve largest private equity firms were twice as likely to default as companies not backed by private equity, with more than half of the companies backed by Platinum Equity and Clearlake Capital at heightened risk of default. Private equity firms' interest in short term profits without regard for the long term effects and the ability to "make money even if their companies blow up" can also lead to job loss, raised prices, and asset stripping for companies acquired. Trade unionists have raised concerns about private-equity-related wage and job cuts, and non-governmental organizations have raised concerns about the loss of transparency when previously public companies become private. ==Major firms==

According to Private Equity International's PEI 300 ranking, the largest private equity firms include The Blackstone Group, Kohlberg Kravis Roberts, EQT AB, Thoma Bravo, The Carlyle Group, TPG Capital, Advent International, Hg, General Atlantic, Warburg Pincus, Silver Lake, Goldman Sachs Alternatives, and Bain Capital. A 2025 report by Qubit Capital supports these rankings, listing Blackstone, Apollo, Carlyle, KKR, TPG, Bain, Warburg Pincus, Vista, and General Atlantic among the leading private equity firms by assets under management. These firms are typically direct investors in companies, focusing primarily on leveraged buyouts, rather than investors in the broader private equity asset class, and for the most part the largest private equity investment firms focused primarily on leveraged buyouts rather than venture capital. ==See also==
