Private equity (PE) refers to investment capital that is not listed on a public stock exchange. Private equity firms raise money from institutional investors and high-net-worth individuals, then deploy that capital by acquiring ownership stakes in private companies. The goal is to improve those companies operationally, grow their value, and eventually sell them at a profit through an exit event such as a sale to another company or an IPO.
For business owners, private equity matters in two key contexts: as a potential source of growth capital or as a type of buyer when you’re ready to sell.
How Private Equity Works
A private equity firm pools capital into a fund with a defined lifespan, typically 10 years. Within the first few years, the firm deploys that capital by acquiring companies. Then it spends the middle years growing those portfolio companies: improving operations, expanding into new markets, making add-on acquisitions, or cutting costs. Finally, it exits those investments in the fund’s later years, returning capital plus gains to its investors.
PE firms often use leverage in their deals: borrowing a portion of the acquisition price so the equity investment goes further. This is called a leveraged buyout (LBO). The debt gets placed on the acquired company’s balance sheet, which is one reason PE ownership can feel intense; the company must generate strong cash flow to service that debt while also hitting growth targets.
Why It Matters for Small Business Owners
Private equity has moved aggressively into the small and mid-market over the last decade. PE-backed roll-ups, where a firm acquires multiple small businesses in the same industry and combines them into a larger entity, are now common in sectors like HVAC, dental practices, landscaping, and home services.
This creates real opportunity for owners of profitable small businesses. A PE firm acquiring your competitor might also want to acquire you as an add-on. Or a lower-middle-market PE firm might approach you directly for a majority stake, giving you liquidity today while keeping you in a management role.
Understanding the basics of PE helps you evaluate these conversations intelligently. EBITDA multiples, earn-outs, rollover equity, and management incentive plans are all PE terms you should know before you sit across the table from a buyer. See how the buy vs. build framework applies to PE-backed competitors and how gross margin affects your PE valuation multiple.
A Real-World Example
A regional HVAC company does $5M in revenue with $800K in EBITDA. A PE firm running an HVAC roll-up offers to buy 80% of the business at a 6x EBITDA multiple, valuing the company at $4.8M. The owner receives $3.84M in cash at closing, retains a 20% stake in the combined roll-up platform, and stays on as regional manager. When the PE firm exits in 5 years at a higher multiple, the owner’s retained stake could be worth far more than the 20% suggests at today’s scale.
Key Takeaways
- Private equity firms raise and deploy capital to acquire, grow, and sell private companies at a profit.
- PE roll-ups are increasingly targeting small businesses in service industries: understanding this landscape gives you leverage as a seller.
- Key deal terms like EBITDA multiples, earn-outs, and rollover equity are negotiating points, not fixed facts. Know what they mean before you negotiate.
