What Is Private Equity?
Private equity firms invest in established businesses, often using debt to fund acquisitions. Learn how PE works and when it is relevant to your business.
Key Takeaways
- Private equity invests in established, profitable businesses — unlike VC which targets early-stage startups
- Leveraged buyouts use debt to amplify returns on acquisition
- PE typically holds businesses for 3-7 years then exits via trade sale or IPO
- PE is relevant to founders who want to sell a stake while continuing to run the business
What private equity is
Private equity (PE) is a form of investment in established, often profitable businesses by funds that raise capital from institutional investors (pension funds, endowments, family offices) and deploy it to acquire or invest in companies. Unlike venture capital, which targets early-stage startups with high growth potential, private equity typically targets mature businesses with predictable cash flows. PE firms seek to improve the operational and financial performance of portfolio companies before exiting 3-7 years later at a profit.
The leveraged buyout
The classic PE transaction is the leveraged buyout (LBO). The PE firm acquires a company using a combination of equity (from the fund) and debt (borrowed against the target company's assets and cash flows) — typically 60-70% debt. The debt amplifies returns if the acquisition works out, because the equity portion is small relative to the total purchase price. The target company then services the debt from its operating cash flows. This structure works well for stable, cash-generative businesses but creates significant financial stress if cash flows disappoint.
Growth equity
Growth equity is a form of PE that sits between venture capital and traditional buyouts. Growth equity investors take minority stakes in profitable, fast-growing businesses that want capital to accelerate — expanding internationally, making acquisitions, or investing in new product lines — without selling a majority of the business. Unlike VC, growth equity targets businesses that have already proven their model and are profitable or near-profitable. For a founder who wants to take chips off the table while continuing to build, growth equity is often the most appropriate structure.
How PE creates value
PE firms create value in portfolio companies through multiple levers. Operational improvement: bringing in experienced management, implementing better processes, and eliminating inefficiency. Financial engineering: optimising the capital structure and using debt tax shields. Strategic repositioning: entering new markets, making bolt-on acquisitions, or exiting underperforming divisions. Revenue growth: professionalising the sales function and marketing, expanding distribution, and improving pricing. The best PE firms are genuine business builders; the worst are financial engineers who extract value at the expense of long-term health.
When PE becomes relevant
Private equity becomes a realistic option for UK businesses with at least £2-3 million EBITDA — though some smaller PE firms will look at businesses with £1 million EBITDA. Founders typically encounter PE in three scenarios: selling a controlling stake and transitioning out of the business, selling a minority stake while continuing to run the business (growth equity), or as part of a management buyout where management acquires the business from retiring founders backed by PE capital. PE due diligence is intensive — financial, legal, commercial, and operational — and the process typically takes 4-6 months from first conversation to closing.
