What Is an Acquisition? Definition, Types, Process, and Examples

An acquisition is a transaction in which a buyer gains control of another business, part of a business, or selected business assets. The buyer is called the acquirer and the business being purchased is called the target. Control can pass through a purchase of shares or ownership interests, an asset purchase, or another legally agreed transaction structure.

Direct answer: In business, an acquisition happens when one company or investor buys enough of another business, or enough of its assets, to control what was purchased. The target may continue as a separate subsidiary, become part of the buyer, or transfer only specified assets and liabilities.

The word can describe a local entrepreneur buying a small company, a private equity firm buying a controlling stake, or a corporation purchasing a competitor. The price matters, but an acquisition also determines which assets, liabilities, contracts, people, rights, and operating responsibilities transfer to the buyer.

Acquisition Meaning in Simple Terms

The simplest acquisition definition is the purchase of control.

Imagine a buyer purchases 80% of a software company. The software company can keep its name, employees, contracts, and legal entity, but the buyer can now direct major business decisions. That is an acquisition because control changed hands.

Now imagine the buyer purchases only the software, customer contracts, brand, and equipment, while the seller keeps its original legal entity. That is also an acquisition, but it is structured as an asset purchase rather than an equity purchase.

Cornell Law School's Legal Information Institute defines acquisition broadly as receiving a good or asset through a transaction or contract and explains that a business buyer may obtain controlling shares. The exact legal, tax, and accounting result depends on the transaction documents and the jurisdictions involved.

Who Is Involved in an Acquisition?

Most acquisitions involve more than a buyer and seller.

The specific team changes with deal size, industry, financing, geography, and regulation. A small owner-operated acquisition may use a compact advisory team. A cross-border corporate acquisition may require specialists across several jurisdictions.

What Is the Difference Between an Acquisition and a Merger?

An acquisition involves one party obtaining control of another business or its assets. A merger is a legal combination of companies. In everyday speech, people often use the terms together as mergers and acquisitions, or M&A, even when a transaction is technically an acquisition.

The U.S. Small Business Administration distinguishes mergers, which combine businesses, from acquisitions, in which a purchased business is taken over by the acquirer. In practice, the legal documents matter more than the headline used to announce the deal.

What Are the Main Types of Acquisitions?

Acquisitions can be classified by what the buyer purchases, why the buyer wants it, how the businesses relate, or how the deal is negotiated.

Asset Acquisition

In an asset acquisition, the buyer purchases specified assets and may assume specified liabilities. Assets can include equipment, inventory, intellectual property, customer contracts, real estate, licenses, data, and goodwill.

This structure lets the parties define what transfers, but contracts, permits, employees, and other rights may require separate assignments or consents. For U.S. federal tax purposes, the IRS explains that a sale of a business can be treated as the sale of separate assets, with the consideration allocated among those assets.

Stock or Equity Acquisition

In a stock or equity acquisition, the buyer purchases shares of a corporation or ownership interests in another entity. The legal entity continues to own its assets and remain responsible for its liabilities, subject to the deal terms and applicable law. What changes is who owns or controls that entity.

Equity purchases can preserve contracts and operating continuity, but the buyer also needs to understand the obligations that remain inside the company.

Majority and Minority Acquisitions

A majority acquisition gives the buyer a controlling ownership position. A minority acquisition purchases less than control, although negotiated voting, board, consent, or governance rights may still give the investor influence over important decisions.

Not every investment is an acquisition. The defining question is whether the buyer obtains control of the business or assets, not simply whether money changes hands.

Horizontal Acquisition

A horizontal acquisition joins businesses operating at a similar level in the same or a closely related market. A company might acquire a competitor to expand coverage, add customers, combine capabilities, or increase scale.

Vertical Acquisition

A vertical acquisition involves a business at another stage of the supply chain. A manufacturer might acquire a supplier, or a distributor might acquire a logistics provider. The goal is often stronger control over cost, capacity, quality, or delivery.

Conglomerate Acquisition

A conglomerate acquisition involves businesses in unrelated markets. Buyers may pursue this structure to diversify revenue, allocate capital across industries, or enter a new field.

Strategic and Financial Acquisitions

A strategic buyer usually acquires a business because it complements existing operations, customers, products, geography, talent, or technology. A financial buyer, such as a private equity firm or acquisition entrepreneur, usually focuses on the target's standalone economics, financing capacity, improvement potential, and future exit options.

Friendly and Hostile Acquisitions

A friendly acquisition proceeds with the target leadership's support. A hostile acquisition is pursued without that support, usually through mechanisms relevant to public companies, such as an offer to shareholders or an attempt to change the board. Most private-company acquisitions are negotiated directly with owners and are not hostile takeovers.

Why Do Companies Make Acquisitions?

Companies make acquisitions when buying an existing capability is more attractive than building it internally or entering through an ordinary commercial partnership.

Common acquisition goals include:

• Entering a market: Gain customers, licenses, distribution, or local knowledge in a new geography or sector.
• Adding a capability: Acquire technology, intellectual property, talent, data, manufacturing, or specialist expertise.
• Increasing scale: Combine revenue, purchasing power, infrastructure, or market coverage.
• Strengthening the value chain: Bring a supplier, distributor, or service provider under common control.
• Diversifying: Add products, customers, or industries that behave differently from the buyer's existing business.
• Deploying capital: Invest available funds in a business expected to create an acceptable return.
• Supporting succession: Transfer an owner-led company to a strategic buyer, management team, employees, or an acquisition entrepreneur.

The acquisition thesis should state exactly how ownership creates value. A vague promise of synergy is not a substitute for named revenue opportunities, cost changes, operational improvements, required investment, responsible owners, and a timetable.

How Does an Acquisition Work?

An acquisition usually moves through eight connected stages. The sequence can overlap, and not every transaction reaches closing.

1. Define the acquisition strategy: The buyer establishes its objectives, target criteria, budget, financing boundaries, risk tolerance, and integration assumptions.
2. Source and screen targets: Buyers, advisors, brokers, and sellers identify possible targets and assess basic fit using available financial, commercial, and operational information.
3. Value the business: The buyer develops a valuation range using the target's performance, assets, risks, market evidence, and expected future cash flows.
4. Make a preliminary offer: The parties may sign an indication of interest or letter of intent covering headline price, structure, exclusivity, financing, diligence, and timing. Many LOI provisions are non-binding, but provisions such as confidentiality and exclusivity may be binding.
5. Conduct due diligence: Specialists test the information behind the investment case and identify risks, liabilities, dependencies, required consents, and integration needs.
6. Negotiate definitive agreements: The parties settle the purchase agreement, price adjustments, representations, warranties, covenants, indemnities, closing conditions, and transition arrangements.
7. Obtain approvals and close: Required corporate, lender, third-party, and regulatory conditions are satisfied; documents are signed; consideration is transferred; and control changes according to the agreement.
8. Integrate and operate: The buyer executes the transition plan, tracks the acquisition thesis, manages people and customers, connects systems, and addresses issues found during diligence.

Key point: Signing and closing are not always the same event. A deal can be signed first and close later after approvals or other conditions are satisfied.

How Is an Acquisition Valued?

An acquisition is valued by estimating what the target is worth to the buyer while accounting for performance, risk, financing, deal structure, and alternatives. No single method produces an unquestionable answer.

Common methods include:

• Comparable company analysis: Applies valuation multiples observed for similar public companies, adjusted for differences.
• Precedent transaction analysis: Reviews prices and multiples paid in comparable past acquisitions.
• Discounted cash flow analysis: Estimates the present value of forecast future cash flows using assumptions about growth, margins, investment, and risk.
• Earnings multiples: Applies a multiple to EBITDA, seller's discretionary earnings, or another normalized earnings measure, depending on the business and market.
• Asset-based valuation: Estimates the value of assets less liabilities and can be especially relevant for asset-heavy or distressed businesses.

Value and price are not identical. The negotiated purchase price can reflect competition, deal certainty, financing, working capital, assumed debt, retained cash, earnouts, rollover equity, tax treatment, and the buyer's view of future benefits.

What Happens During Acquisition Due Diligence?

Acquisition due diligence is the structured investigation a buyer performs before closing. Its purpose is to verify the investment case, identify risks, confirm what is being purchased, and determine what must be reflected in price, structure, contracts, or the integration plan.

Due diligence is not a box-checking exercise. A finding should lead to a decision: proceed, investigate further, change the price, change the structure, require a protection, redesign the transition, or leave the deal.

How Are Acquisitions Financed?

An acquisition can be financed with buyer cash, new debt, investor equity, shares issued to the seller, seller financing, or a combination. The structure determines who bears risk and when the seller receives value.

Common components include:

• Cash paid at closing
• Bank or private credit debt
• Equity contributed by the buyer or outside investors
• Buyer shares issued to the seller
• Seller notes paid over time
• Earnouts tied to defined post-closing results
• Rollover equity retained or reinvested by the seller

The headline purchase price does not reveal the full economics. Buyers and sellers also examine debt, cash, working-capital adjustments, contingent payments, escrows, holdbacks, fees, and the timing and certainty of each payment.

A Simple Acquisition Example

Suppose a regional business-services company wants to enter a neighboring market. Building a new operation would require recruiting a team, finding customers, establishing delivery processes, and developing local relationships.

Instead, it agrees to acquire 100% of a local provider. The buyer values the target, signs an LOI, reviews the financials, customer contracts, staff, systems, and legal obligations, arranges financing, negotiates the purchase agreement, and closes after the required conditions are met.

After closing, the target may keep its brand and operate as a subsidiary, or the buyer may integrate it into the existing company. In either case, the transaction is an acquisition because the buyer gained control.

What Can Cause an Acquisition to Fail?

An acquisition can fail before closing or disappoint after closing. Frequent causes include:

• The strategic reason for buying the target was never made specific.
• Forecasts or expected synergies were too optimistic.
• Due diligence missed a material liability or operating dependency.
• The buyer paid more than the realistic value it could create.
• Financing became unavailable or too expensive.
• Required approvals, consents, or closing conditions were not obtained.
• Customers, employees, suppliers, or leaders left during the transition.
• Systems, data, incentives, decision rights, and cultures were not integrated deliberately.
• The integration team lost track of the assumptions that justified the deal.

Good execution depends on continuity between sourcing, valuation, diligence, closing, and integration. When information is repeatedly copied between inboxes, spreadsheets, models, documents, and a CRM, teams lose time and introduce avoidable inconsistencies.

How Deal Operations Support an Acquisition

Deal operations are the systems, data flows, responsibilities, and controls that move an acquisition from first contact to close. A strong operation does not make the investment decision. It ensures the people responsible for that decision receive consistent information, clear next actions, and traceable work.

A connected M&A operating system can help a transaction team:

• Capture target information once and keep the CRM current.
• Apply acquisition criteria consistently during screening.
• Prepare valuation inputs from verified source data.
• Track diligence requests, missing documents, owners, and deadlines.
• Draft repeatable documents while preserving expert review.
• Surface exceptions and approval requirements before work moves forward.
• Maintain an audit trail across handoffs and material actions.

AI and automation are useful when they handle defined preparation, coordination, and data movement. Valuations, investment conclusions, legal decisions, and consequential communications should remain subject to qualified human judgment and approval.

Frequently Asked Questions

What is an acquisition in one sentence?

An acquisition is a transaction in which a buyer gains control of another business, part of a business, or selected assets by purchasing shares, ownership interests, assets, or another agreed form of control.

Is an acquisition the same as buying a company?

Often, yes. Buying a controlling interest in a company is an acquisition. However, an acquisition can also involve buying a division, product line, or selected group of assets rather than the entire legal entity.

Is an acquisition the same as a merger?

No. An acquisition has an identifiable buyer that gains control of a target or its assets. A merger legally combines entities. The terms are often grouped together as M&A, and a transaction described publicly as a merger may still have a clear acquirer in economic terms.

What is the difference between an acquisition and a takeover?

A takeover is generally an acquisition of control. The word is often used when the target is a public company or when emphasizing that control changed hands. A takeover can be friendly or hostile, while most private acquisitions are negotiated with the owners.

What are the three main types of acquisitions?

The most useful structural categories are asset acquisitions, stock or equity acquisitions, and transactions completed through a legal merger structure. Acquisitions are also described as horizontal, vertical, or conglomerate based on the relationship between the buyer and target.

What is the first step in an acquisition?

The first step is to define the acquisition strategy: why the buyer wants to acquire, what a suitable target looks like, how much it can invest, which risks it will accept, and how the acquired business would create value after closing.

How long does an acquisition take?

There is no universal timeline. A small private acquisition can move relatively quickly, while a complex, financed, regulated, or cross-border transaction can take many months or longer. Readiness, diligence findings, financing, negotiation, approvals, and third-party consents all affect timing.

Who owns the company after an acquisition?

The answer depends on the structure. In an equity acquisition, the buyer owns the purchased shares or interests and may control the target as a subsidiary. In an asset acquisition, the buyer owns the transferred assets and assumes the liabilities defined by the agreement, subject to applicable law.

What happens to employees after an acquisition?

Employees may remain with the target, transfer to the buyer, receive new terms, change roles, or leave. The result depends on the transaction structure, local employment law, integration plan, and individual agreements. Buyers should address workforce continuity during diligence and transition planning.

Do all announced acquisitions close?

No. A transaction can end if diligence reveals unacceptable risks, financing fails, approvals are not obtained, closing conditions are not satisfied, or the parties cannot agree final terms. An announcement or signed LOI does not necessarily mean control has transferred.

Is acquisition information legal, tax, or investment advice?

No. This guide provides general educational information. Acquisition structures and obligations vary by entity, contract, industry, tax profile, and jurisdiction. Buyers and sellers should obtain advice from qualified legal, tax, financial, and regulatory professionals for a specific transaction.
