What Is an Acquisition?

What Is an Acquisition?

An acquisition is a business transaction in which one person or company obtains ownership or control of another business, company, asset, or group of assets.

In ordinary language, an acquisition means one business buys another business or buys something that belongs to another business. In corporate law, however, the structure of the transaction matters enormously. A company might acquire another company by purchasing its stock, acquire selected assets without buying the entire company, or obtain control through another form of transaction.

The word acquisition therefore describes a broad economic result—one party obtains ownership or control—rather than one single legal procedure.

Cornell Law School’s Legal Information Institute explains acquisition in similar terms, including the purchase of a business through its stock or shares. See Cornell Wex: Acquisition.

Acquisitions are a central part of business law, corporate law, securities law, contract law, tax law, and antitrust law. They can involve relatively small private companies or transactions worth billions of dollars.

1. The Basic Idea of an Acquisition

The simplest acquisition looks like this:

Buyer → purchases → Target

The buyer, often called the acquirer, obtains ownership or control of the target.

For example, suppose Company A operates a software business and Company B operates a smaller software company.

Company A may decide to purchase Company B.

If the transaction is completed, Company A has acquired Company B.

But the legal consequences depend on what Company A actually purchased.

It might purchase:

• all of Company B’s stock;
• a controlling percentage of Company B’s stock;
• substantially all of Company B’s assets;
• selected assets;
• a business division;
• intellectual property;
• real estate;
• contracts;
• customer relationships;
• or another identifiable business interest.

Thus, the first question in analyzing an acquisition is:

What exactly has been acquired?

That question determines much of the legal structure that follows.

---

2. Acquisition vs. Purchase

The words purchase and acquisition are sometimes used interchangeably, but they are not always identical.

A purchase generally describes the act of buying something.

An acquisition emphasizes the resulting ownership or control.

For example, a company may purchase:

• equipment;
• land;
• patents;
• inventory;
• shares;
• or another company.

The purchase of a company’s shares may therefore constitute an acquisition of the company.

But a company can also acquire assets without acquiring the legal entity that owns them.

This distinction becomes extremely important in corporate transactions.

---

3. Who Are the Parties to an Acquisition?

Most acquisitions involve at least two principal parties.

The Acquirer

The acquirer is the person or entity obtaining the business, shares, assets, or control.

The acquirer may be:

• a corporation;
• an LLC;
• a partnership;
• a private-equity fund;
• an investment company;
• an individual;
• or another business organization.

The Target

The target is the business, company, asset, or ownership interest being acquired.

In a stock acquisition, the target is generally the corporation whose shares are being purchased.

In an asset acquisition, the target may be selling only specified assets rather than the entire company.

The Sellers

The sellers depend on the structure of the transaction.

In a stock acquisition, shareholders may be the sellers.

In an asset acquisition, the corporation or other business entity owning the assets may be the seller.

This distinction matters because the identity of the seller determines who receives the purchase price.

---

4. What Can Be Acquired?

An acquisition does not necessarily mean buying an entire corporation.

A business may acquire virtually any legally transferable economic interest.

Common examples include:

Stock

A buyer may purchase shares of a corporation.

If enough voting shares are acquired, the buyer may obtain control of the corporation.

Assets

A buyer may purchase specific business assets.

These might include:

• machinery;
• buildings;
• inventory;
• intellectual property;
• trademarks;
• patents;
• copyrights;
• customer lists;
• contracts;
• accounts;
• technology;
• or real estate.

A Business Division

A large corporation may sell one division while retaining the rest of its business.

Another company may acquire that division and integrate it into its own operations.

A Controlling Interest

A buyer does not necessarily need to purchase every share.

If a buyer obtains enough voting power to control corporate decisions, it may effectively acquire control while other shareholders remain owners.

This is one reason why ownership and control should not automatically be treated as identical concepts.

---

5. Stock Acquisition

A stock acquisition occurs when the buyer purchases shares of the target company from its shareholders.

For example:

• Company B has 1,000 outstanding shares.
• Company A purchases 700 shares.
• Company A now owns 70% of Company B.

If those shares carry voting rights sufficient to control the corporation, Company A may now control Company B.

Company B may continue to exist as a separate legal entity.

This is a crucial feature of many acquisitions.

The transaction may change who owns and controls the corporation without eliminating the corporation itself.

The target can therefore become a subsidiary of the acquiring company.

Example

Imagine:

Parent Company
↓
Target Subsidiary

The target remains a corporation, but its ownership has changed.

This is different from a merger in which one corporation may be absorbed into another.

---

6. Asset Acquisition

An asset acquisition operates differently.

Instead of purchasing the ownership interests of the company, the buyer purchases specified assets.

For example, Company A might purchase:

• Company B’s factory;
• its machinery;
• its trademarks;
• its inventory;
• and certain customer contracts.

But Company A does not necessarily purchase Company B itself.

Company B may continue to exist after the transaction.

This creates an important distinction:

Buying a company is not necessarily the same thing as buying the company’s assets.

The distinction can affect:

• liabilities;
• contracts;
• employees;
• intellectual property;
• licenses;
• permits;
• taxes;
• litigation;
• and regulatory obligations.

---

7. Stock Acquisition vs. Asset Acquisition

The difference can be summarized simply.

Stock Acquisition	Asset Acquisition
Buyer purchases shares	Buyer purchases specified assets
Target company generally remains intact	Seller may retain the legal entity
Ownership changes	Ownership of selected assets changes
Buyer generally acquires the company together with its existing legal structure	Buyer can select which assets and liabilities are assumed
Shareholders generally receive the purchase price	Selling company generally receives the purchase price
Existing liabilities generally remain with target company	Allocation of liabilities depends heavily on the transaction

The legal and economic consequences can be substantially different.

That is why acquisition lawyers spend considerable time determining which structure best fits the transaction.

---

8. Acquisition vs. Merger

One of the most important distinctions in corporate law is the difference between an acquisition and a merger.

In a basic acquisition, one company obtains ownership or control of another company while the two legal entities may continue to exist separately.

In a merger, two corporations combine through a legally defined transaction in which one entity may survive and the other disappear as a separate legal entity.

Cornell Wex describes a corporate merger as the absorption of one corporation into another, with the surviving corporation acquiring the assets and liabilities of the absorbed corporation. See Cornell Wex: Merger.

Acquisition

A + B → A owns or controls B

Merger

A + B → A or a new entity survives

The terminology can sometimes be confusing because the business world frequently uses “mergers and acquisitions”—or M&A—as a general expression covering many different transactions.

---

9. What Is M&A?

M&A stands for mergers and acquisitions.

It refers broadly to transactions through which businesses are combined, purchased, reorganized, or brought under common ownership or control.

M&A transactions can include:

• mergers;
• stock purchases;
• asset purchases;
• tender offers;
• takeovers;
• consolidations;
• certain reorganizations;
• and other corporate combinations.

Cornell Wex describes M&A as a legal practice area involving transactions such as mergers, asset purchases, tender offers, and hostile takeovers.

Thus, an acquisition is one important category within the larger field of M&A.

---

10. Why Do Companies Acquire Other Companies?

Acquisitions can serve many different business purposes.

Market Expansion

A company may acquire another business to enter a new market.

For example, a U.S. company may acquire an established company operating in another country rather than building a new operation from scratch.

Increased Market Share

A company may acquire a competitor to increase its share of an existing market.

This can create substantial economic efficiencies—but it can also raise antitrust concerns.

Access to Technology

A technology company may acquire another company because it owns valuable:

• patents;
• software;
• algorithms;
• intellectual property;
• or specialized technical knowledge.

Access to Customers

An established customer base can be one of the most valuable parts of a business.

An acquisition can therefore provide immediate access to customers and commercial relationships.

Talent

A company may acquire another business partly because of its employees and management team.

This is sometimes associated with the term acqui-hire, particularly in technology businesses.

Economies of Scale

Larger organizations may be able to operate more efficiently.

Combining purchasing, distribution, technology, administration, or production can reduce costs.

Diversification

A company may acquire a business operating in an entirely different industry.

Diversification can reduce dependence on one market, although it can also create management and integration challenges.

---

11. Friendly Acquisitions

A friendly acquisition occurs when the target’s management and board generally cooperate with the transaction.

The buyer and target negotiate the terms.

The process may involve:

1. preliminary discussions;
2. confidentiality agreements;
3. due diligence;
4. valuation;
5. negotiation;
6. a definitive acquisition agreement;
7. required board or shareholder approvals;
8. regulatory approvals where applicable;
9. closing.

Friendly acquisitions are generally negotiated transactions.

The target’s board may determine that the proposed transaction is in the best interests of the corporation and its shareholders, subject to the applicable law and fiduciary duties.

---

12. Hostile Acquisitions

An acquisition becomes hostile when the target company’s management or board does not support the proposed takeover.

The buyer may attempt to obtain control directly from shareholders or through other means.

Two classic mechanisms are:

• a tender offer; and
• a proxy contest.

In a tender offer, the acquirer offers to purchase shares directly from shareholders, often at a premium.

In a proxy contest, the acquirer seeks shareholder votes to replace directors or otherwise change corporate control.

Cornell Wex defines a hostile takeover as an acquisition in which the target’s board does not approve the transaction and identifies tender offers and proxy contests as common mechanisms.

Hostile transactions therefore demonstrate an important principle of corporate law:

Control of a corporation ultimately involves the relationship among management, directors, shareholders, and voting rights.

---

13. The Role of the Board of Directors

In many corporate acquisitions, the board of directors plays a central role.

Directors may be responsible for evaluating whether the proposed transaction is appropriate for the corporation and its shareholders.

Depending on the circumstances and applicable state law, directors may need to consider:

• the purchase price;
• the value of the target;
• strategic alternatives;
• financial consequences;
• shareholder interests;
• regulatory risks;
• conflicts of interest;
• and the consequences of accepting or rejecting the transaction.

Acquisitions can therefore raise significant questions involving fiduciary duties.

A transaction in which directors have a personal financial interest may receive heightened scrutiny.

---

14. Due Diligence

Before completing a significant acquisition, the buyer generally conducts due diligence.

Due diligence means investigating the target and the transaction before committing to the deal.

The buyer may examine:

Corporate Records

• formation documents;
• bylaws;
• shareholder agreements;
• board minutes;
• capitalization records.

Financial Information

• financial statements;
• debts;
• liabilities;
• revenue;
• expenses;
• tax obligations.

Contracts

The buyer may review:

• major customer contracts;
• supplier agreements;
• leases;
• financing agreements;
• licenses;
• employment agreements.

Litigation

The buyer may investigate:

• pending lawsuits;
• threatened claims;
• regulatory proceedings;
• intellectual-property disputes.

Intellectual Property

The buyer may examine:

• patents;
• trademarks;
• copyrights;
• trade secrets;
• software;
• licenses.

Employment Matters

The investigation may include:

• employee contracts;
• compensation;
• benefits;
• restrictive covenants;
• pending employment disputes.

The purpose is not merely to discover whether the business is profitable.

It is to discover what the buyer is actually buying.

---

15. The Acquisition Agreement

After negotiations and due diligence, the parties generally document the transaction in a detailed agreement.

Depending on the structure, this may be called a:

• Stock Purchase Agreement;
• Share Purchase Agreement;
• Asset Purchase Agreement;
• Merger Agreement;
• or another transaction-specific agreement.

The agreement normally addresses matters such as:

• purchase price;
• payment structure;
• representations and warranties;
• covenants;
• conditions to closing;
• indemnification;
• termination rights;
• regulatory approvals;
• closing procedures;
• and post-closing obligations.

The acquisition agreement is therefore more than a simple promise to buy.

It is a mechanism for allocating risk between the buyer and seller.

---

16. Purchase Price

The purchase price is obviously central to an acquisition.

But the price may not consist entirely of cash.

An acquisition may be structured using:

• cash;
• shares of the buyer;
• debt financing;
• a combination of cash and stock;
• earn-outs;
• contingent consideration;
• or other forms of consideration.

Example

Suppose Company A agrees to acquire Company B for $100 million.

The agreement might provide:

• $70 million in cash at closing;
• $20 million in shares of Company A;
• and up to $10 million in additional consideration if Company B reaches specified performance targets.

The headline purchase price therefore may not tell the entire economic story.

---

17. Representations and Warranties

One of the most important parts of an acquisition agreement is the set of representations and warranties.

The seller may represent that:

• the company is properly organized;
• its financial statements are accurate in specified respects;
• it owns particular assets;
• it has disclosed material litigation;
• its contracts are valid;
• its intellectual-property rights are properly identified;
• and specified legal requirements have been satisfied.

The buyer relies on these statements when deciding whether to complete the transaction.

If a representation is false, the agreement may provide remedies depending on its terms.

---

18. Conditions to Closing

Signing the acquisition agreement does not necessarily mean the transaction is immediately completed.

The agreement may establish conditions to closing.

These could include:

• obtaining regulatory approval;
• receiving shareholder approval;
• obtaining third-party consents;
• satisfying financing conditions;
• completing required filings;
• absence of certain material adverse changes;
• or compliance with specified contractual obligations.

The transaction closes only when the required conditions have been satisfied or appropriately waived.

---

19. What Happens at Closing?

Closing is the point at which the transaction is legally completed according to the acquisition agreement.

Depending on the transaction, closing may involve:

• payment of the purchase price;
• transfer of shares;
• transfer of assets;
• delivery of certificates;
• execution of additional documents;
• resignation or appointment of directors;
• delivery of required consents;
• and other specified actions.

After closing, the buyer generally obtains the ownership or control contemplated by the transaction.

---

20. Post-Closing Obligations

The transaction does not necessarily end when the purchase price is paid.

The parties may have continuing obligations.

These can include:

• indemnification;
• adjustment of the purchase price;
• earn-out calculations;
• transitional services;
• confidentiality;
• non-solicitation obligations;
• intellectual-property assignments;
• cooperation with regulatory matters;
• and other contractual duties.

Thus, an acquisition can create a legal relationship that continues for months or years after closing.

---

21. Acquisitions and Liabilities

One of the most important legal questions is:

Who becomes responsible for the target’s liabilities?

The answer depends heavily on the transaction structure and applicable law.

In a stock acquisition, the target corporation generally continues to own its assets and remain responsible for its existing obligations.

The buyer has purchased the ownership interest in that corporation.

In an asset acquisition, the buyer may acquire selected assets and assume only specified liabilities, although applicable law can impose liabilities in particular circumstances.

These distinctions are among the reasons due diligence is so important.

---

22. Acquisition and Antitrust Law

An acquisition can create competition-law concerns.

Suppose the largest company in an industry attempts to acquire its closest competitor.

The transaction may increase market concentration and potentially reduce competition.

Federal antitrust law can therefore become relevant to acquisitions.

The legal question is not simply:

“Can Company A afford to buy Company B?”

It may also be:

“Would allowing Company A to acquire Company B substantially harm competition?”

This is why certain acquisitions require regulatory review.

The antitrust dimension becomes particularly important in transactions involving large companies, concentrated markets, or strategically important assets.

---

23. Acquisition of a Private Company

Acquiring a private company is often different from acquiring a public company.

A private-company acquisition may involve:

• a smaller number of shareholders;
• extensive private negotiations;
• confidentiality agreements;
• detailed due diligence;
• privately negotiated valuation;
• fewer public disclosure obligations;
• and customized contractual arrangements.

The buyer may negotiate directly with the owners.

For example, a founder-owned company might be sold to a larger corporation through a privately negotiated stock purchase agreement.

---

24. Acquisition of a Public Company

Public-company acquisitions can involve additional securities-law and corporate-law considerations.

The target may have:

• thousands or millions of shareholders;
• publicly traded stock;
• securities-law disclosure obligations;
• institutional investors;
• exchange requirements;
• and a board accountable to shareholders under applicable corporate law.

A public acquisition may therefore involve:

• tender offers;
• proxy materials;
• securities filings;
• shareholder votes;
• regulatory review;
• and extensive public disclosure.

The complexity can be substantially greater than in a private-company transaction.

---

25. Acquisition vs. Takeover

The terms acquisition and takeover overlap, but they are not always identical.

An acquisition generally refers to obtaining ownership or control.

A takeover emphasizes a change in corporate control.

A takeover may be friendly or hostile.

An acquisition may be friendly, negotiated, or hostile depending on the circumstances.

Thus:

A takeover can be an acquisition, but not every acquisition is commonly described as a takeover.

For example, purchasing a small minority interest in a company may technically be an acquisition of shares but may not constitute a corporate takeover.

---

26. Acquisition vs. Investment

An acquisition should also be distinguished from an ordinary investment.

Suppose an investor buys 2% of a public company’s stock.

That is an investment and an acquisition of shares.

But it ordinarily does not give the investor control of the company.

Now suppose another company purchases 80% of the voting shares.

That transaction may constitute an acquisition of control.

The critical issue is therefore not merely whether something was purchased, but what ownership, economic rights, and control resulted.

---

27. Why Acquisition Structure Matters

The structure of an acquisition affects nearly every major legal issue in the transaction.

It can affect:

• what is transferred;
• who receives the purchase price;
• which liabilities remain with the seller;
• which contracts must be transferred;
• whether third-party consent is required;
• tax consequences;
• employee relationships;
• intellectual-property ownership;
• regulatory approval;
• shareholder rights;
• and post-closing obligations.

The same business could therefore produce very different legal consequences depending on whether it is acquired through a stock purchase, asset purchase, merger, or another structure.

---

28. A Simple Acquisition Example

Imagine that TechCo wants to acquire SmallSoft, a software company.

SmallSoft owns:

• software;
• patents;
• trademarks;
• customer contracts;
• employees;
• equipment;
• and $2 million in debt.

TechCo has several options.

Option 1: Stock Acquisition

TechCo purchases all of SmallSoft’s shares.

SmallSoft remains a legal entity.

TechCo becomes its owner.

The existing corporate structure and liabilities generally remain with SmallSoft.

Option 2: Asset Acquisition

TechCo purchases SmallSoft’s software, patents, trademarks, and selected contracts.

SmallSoft retains other assets and liabilities.

The acquisition agreement determines which liabilities TechCo assumes, subject to applicable law.

Option 3: Merger

SmallSoft merges into TechCo or another entity.

The legal consequences are governed by the applicable merger statute and transaction documents.

These three transactions may produce economically similar results—TechCo obtains the business—but legally they are quite different.

29. The Acquisition Process

A simplified acquisition process looks like this:

1. Strategic decision

The buyer identifies a potential target.

↓

2. Preliminary negotiations

The parties discuss whether a transaction is possible.

↓

3. Confidentiality

The parties may enter into confidentiality agreements.

↓

4. Due diligence

The buyer investigates the target.

↓

5. Valuation

The parties determine what the business may be worth.

↓

6. Negotiation

The parties negotiate price, structure, risk allocation, and other terms.

↓

7. Definitive agreement

The parties sign the acquisition agreement.

↓

8. Approvals

Required shareholder, regulatory, lender, or third-party approvals are obtained.

↓

9. Closing

The transaction is completed.

↓

10. Integration and post-closing

The buyer integrates the acquired business and the parties perform continuing obligations.

This sequence is simplified. Real transactions can be much more complicated and may involve multiple negotiations, regulatory reviews, financing arrangements, and simultaneous agreements.

---

30. Why Acquisitions Sometimes Fail

Not every acquisition produces the expected benefits.

A buyer may overestimate:

• the target’s value;
• expected cost savings;
• customer retention;
• technological advantages;
• market growth;
• or potential synergies.

Integration can also be difficult.

Two companies may have incompatible:

• corporate cultures;
• management systems;
• technologies;
• compensation structures;
• business practices;
• or strategic objectives.

An acquisition can therefore be legally successful while being economically unsuccessful.

That distinction is important.

Closing the transaction does not guarantee that the transaction was a good business decision.

---

31. The Concept of Synergy

One reason companies pursue acquisitions is the possibility of synergy.

Synergy means that the combined businesses may create more value together than they could separately.

In simplified form:

Value of A + Value of B < Value of A + B combined

For example, Company A may have excellent technology while Company B has a large distribution network.

Together, they may generate more revenue than either company could generate independently.

But projected synergies are estimates, not guarantees.

This is one reason valuation and due diligence are fundamental components of acquisition law and practice.

---

32. The Legal Architecture of an Acquisition

An acquisition often sits at the intersection of several areas of law.

Corporate Law

Determines issues involving:

• directors;
• shareholders;
• corporate authority;
• voting;
• mergers;
• and corporate governance.

Contract Law

Governs:

• acquisition agreements;
• representations;
• warranties;
• covenants;
• indemnification;
• and closing obligations.

Securities Law

May regulate:

• public-company transactions;
• tender offers;
• shareholder disclosures;
• insider trading;
• and securities issued as consideration.

Antitrust Law

May restrict acquisitions that threaten competition.

Tax Law

Can influence the choice between:

• stock transactions;
• asset transactions;
• reorganizations;
• and other structures.

Employment Law

Can affect:

• employees;
• benefits;
• executive contracts;
• and post-acquisition employment relationships.

Intellectual Property Law

Determines how:

• patents;
• trademarks;
• copyrights;
• software;
• and trade secrets

are transferred or licensed.

An acquisition is therefore not simply a purchase contract.

It is a multi-layered legal transaction.

---

34. Frequently Asked Questions

What is an acquisition in business?

An acquisition is a transaction in which one person or business obtains ownership or control of another business, asset, or ownership interest.

Is an acquisition the same as a merger?

No. In an acquisition, one party generally obtains ownership or control of another business. In a merger, two entities legally combine, often resulting in one surviving entity or a newly formed entity.

What is the difference between an acquisition and a takeover?

An acquisition generally describes obtaining ownership or control. A takeover emphasizes a change in control of a company and is often discussed in the context of public corporations.

What is a stock acquisition?

A stock acquisition occurs when the buyer purchases shares of the target company. If sufficient voting shares are acquired, the buyer may obtain control of the company.

What is an asset acquisition?

An asset acquisition occurs when a buyer purchases specified assets of a business rather than purchasing the ownership interests in the company itself.

Why do companies acquire other companies?

Companies may acquire other businesses to expand into new markets, increase market share, obtain technology or intellectual property, acquire customers, achieve economies of scale, obtain talent, or pursue strategic growth.

What is due diligence in an acquisition?

Due diligence is the investigation of the target’s financial, legal, contractual, operational, corporate, intellectual-property, employment, and other affairs before the transaction is completed.

Can an acquisition be hostile?

Yes. A hostile acquisition occurs when the target’s management or board does not support the proposed takeover. Tender offers and proxy contests are common mechanisms associated with hostile takeovers.

Does buying a company mean buying its liabilities?

Not necessarily in the same way for every transaction. The consequences depend on whether the buyer purchases stock, assets, or another interest, as well as applicable law and the transaction documents.

What is an acquisition agreement?

An acquisition agreement is the principal contract documenting the transaction. Depending on the structure, it may be a stock purchase agreement, asset purchase agreement, merger agreement, or another form of definitive transaction document.

---

Conclusion

An acquisition is one of the fundamental mechanisms through which businesses change ownership and control.

At its simplest, the concept is straightforward: one party acquires something that previously belonged to another party.

The legal analysis, however, can be considerably more complex.

The central question is not merely whether a business was “bought.” It is what was bought, how it was bought, who now controls it, which liabilities followed the transaction, and what legal consequences arise from the chosen structure.

A buyer may purchase shares and acquire control of an entire corporation. It may instead purchase selected assets and leave the selling company behind. It may negotiate a merger, make a tender offer, or pursue another corporate transaction.

Understanding these distinctions provides the foundation for studying the broader field of mergers and acquisitions law.

The next stage of analysis is therefore to examine the principal acquisition structures in greater detail—especially stock acquisitions versus asset acquisitions, because that distinction determines much of the legal and economic architecture of an acquisition.
