Private equity: sell a large stake to fund growth, a buyout or founder exit

Private equity is usually aimed at mature businesses rather than startups. A private-equity fund invests substantial capital, often taking a large or controlling stake, and then works with management to increase the company's value before selling the investment several years later.

Private equity normally targets established businesses

The British Business Bank describes private equity as medium to long-term finance for mature businesses. It is commonly used for buyouts, management succession and larger growth plans rather than the earliest startup stage.

Investments are often measured in millions and can involve a majority stake. Founders should therefore view the transaction partly as ownership change, not merely fundraising.

The investor can take significant board and strategic control

Private-equity investors frequently seek board seats and influence over strategy, management appointments, budgets and future acquisitions. Some transactions involve control above 50 percent.

Shareholders should negotiate governance as carefully as price. A high valuation can be less attractive if the seller retains little control over decisions they consider essential.

Private equity often uses debt alongside equity

Leveraged buyouts use a mix of investor equity and borrowing to acquire the company. British Business Bank notes that debt providers can finance part of the purchase and refinance existing facilities.

The acquired business can then carry substantial debt service. Management should understand the post-deal capital structure and covenant headroom before celebrating the purchase price.

Expect extensive commercial, financial and legal due diligence

Private-equity investors and their advisers review accounts, tax, customers, contracts, management, technology, legal risk and the growth plan. The process can take many months.

Prepare a data room and reconcile the company's banking, debt and cash records before the process becomes competitive. Unexplained financial items weaken credibility and can reduce price.

Separate money paid to selling shareholders from money invested into the company

A transaction can include secondary consideration to existing owners and primary capital injected into the business. Those are economically different cash flows.

Money paid to a founder for their shares does not become company working capital. Finance should model sources and uses clearly so management knows how much cash remains inside the business after completion.

Private-equity investors plan an exit from the beginning

British Business Bank guidance says PE funds typically hold investments for several years before selling to another investor, corporate buyer or public market.

Management should understand the expected exit horizon and what performance targets drive value. Taking private equity means accepting that another ownership transaction is likely part of the plan.

Worked example: a founder sells 60 percent of a company for £12 million while the PE investor also injects £3 million of fresh growth capital. The £12 million paid to the seller is not company cash; only the £3 million primary investment strengthens the balance sheet. Treasury and the board should model the post-deal company using the actual cash that remains inside the business.

Management incentives can change materially after the deal. PE investors often use new option or sweet-equity structures to align executives with the exit plan. Founders staying in the business should understand their rolled-over equity, leaver provisions and what happens under different exit values.

Leverage can amplify both return and risk. If the deal adds acquisition debt, cash that previously funded dividends or growth may be needed for interest and principal. The board should see post-transaction free cash after debt service, not only EBITDA improvement targets.

Build a post-deal 13-week cash forecast before signing. Integration costs, adviser fees, refinancing expenses and management changes can consume cash immediately even when the investment case is attractive over five years. The first quarter after completion should not rely on optimistic synergy assumptions.

Review banking mandates on completion day. A change of ownership can require lender consent, new board authorities and updates to signatories. The company should not discover after closing that the old founder remains the only person able to approve payroll or access a key account.

Review customer and supplier change-of-control clauses during diligence. A deal can affect key contracts even if the operating company name and bank account remain unchanged. Finance should flag contracts where consent, notice or new security is required so the transaction does not create an unexpected revenue or supply interruption after completion.

Prepare management for a different reporting rhythm. PE ownership often means more frequent KPI, cash, covenant and board reporting than founder-owned businesses previously used. Investing in reliable management information before completion can reduce friction after the deal and help leadership spend less time rebuilding numbers for every board meeting.
