M&A for beginners: how an acquisition works

M&A means mergers and acquisitions: transactions that combine businesses or transfer control of a business. The useful beginner question is not simply “what is the price?” but “why should these businesses be worth more together?”

Merger, acquisition and deal structure

A merger combines businesses; an acquisition involves a buyer acquiring control. Headlines sometimes use these labels loosely. An acquisition may involve shares or selected assets, and payment may be cash, buyer shares or a combination. The structure affects what is bought and which liabilities or risks need investigation.

A fictional HC deal

Imagine Northbridge Software considering the purchase of a smaller scheduling company. The target reaches customers Northbridge has struggled to serve. Northbridge believes its sales team could distribute both products, but that assumption needs evidence: customer interviews, product compatibility and a realistic sales plan.

The target has £2 million of EBITDA. An illustrative 7× multiple implies £14 million of enterprise value. With £3 million of debt and £1 million of cash, simplified equity value is £12 million. Actual completion payments can involve working-capital adjustments, fees and other claims. The equity cheque and enterprise value are different numbers.

The process in six steps

1. Strategy: define what the buyer needs and compare buying with building or partnering.
2. Screening: identify businesses that fit those needs.
3. Valuation: explore standalone value, synergies and downside cases.
4. Due diligence: investigate financial, commercial, operational and legal assumptions.
5. Agreement and closing: negotiate terms and satisfy required approvals and conditions.
6. Integration: implement the operating plan and measure whether the expected benefits appear.

Synergies must survive the costs

Suppose the buyer expects £400,000 of annual savings, but integration costs £900,000 upfront and disrupts sales. The savings are not immediately available profit. Their timing, delivery risk and implementation costs belong in the analysis. Revenue synergies also require a credible explanation of who will buy more and why.

Questions before calling a deal successful

What could customers or employees do differently? Which technology systems need combining? Who owns the integration plan? Can the buyer fund the transaction if trading weakens? Regulatory review can also matter; the linked UK CMA resource explains its role without implying every acquisition requires the same process.
