Frequently Asked Questions

What does acquisition mean in business?

An acquisition is when one company purchases another company or its assets. The acquiring company takes control of the target company, which may continue operating as a subsidiary or be fully absorbed into the acquirer's operations. Acquisitions can be friendly (negotiated agreement) or hostile (against management's wishes).

What is the difference between a merger and an acquisition?

In a merger, two companies combine to form a new entity, with shareholders of both companies receiving shares in the new company. In an acquisition, one company purchases another, and the acquirer retains its identity while the target company ceases to exist as an independent entity (though it may continue as a subsidiary). In practice, even transactions labeled as 'mergers' often have one dominant party.

What is due diligence in M&A?

Due diligence is the comprehensive investigation and analysis of a target company before completing an acquisition. It typically covers financial records, legal matters, operations, customers, employees, and compliance. The goal is to verify seller representations, identify risks, and inform the final purchase price and deal structure.

What is a Letter of Intent (LOI)?

A Letter of Intent (LOI) is a document outlining the preliminary terms of a proposed acquisition. Most LOI terms are non-binding (price, structure), but certain provisions like confidentiality and exclusivity are typically binding. The LOI establishes the framework for due diligence and final negotiations.

What is an earnout in M&A?

An earnout is a portion of the purchase price that is contingent on the business achieving certain performance targets after closing. Earnouts are used to bridge valuation gaps between buyer and seller, allowing sellers to capture additional value if the business performs well under new ownership.

What is EBITDA and why does it matter in acquisitions?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It's a measure of operating profitability used to value businesses and compare them across industries. Business valuations are often expressed as a multiple of EBITDA (e.g., '5x EBITDA'). Adjusted EBITDA normalizes for one-time expenses and owner benefits.
