A takeover in business refers to a transaction in which one company obtains control of another. The acquiring firm is commonly called the acquirer or bidder, and the company being acquired is the target. Takeovers can transfer legal ownership through purchase of shares, purchase of assets, or by combining entities in a merger. They play a central role in corporate strategy, enabling rapid growth, access to new markets or technologies, and changes in corporate structure.

Key terms and basic mechanics

Common mechanisms include a negotiated merger agreement, a direct purchase of the target's shares, or a tender offer—a public proposal to shareholders to sell their stock at a specified price. Another approach is a proxy contest: the bidder attempts to replace the target's board to secure approval. Consideration paid to sellers may be cash, stock, debt assumption, or a mix. Before a transaction completes, parties conduct due diligence to assess assets, liabilities, contracts, and regulatory risks.

Types of takeovers

  • Friendly takeover: The target's management and board negotiate terms and recommend the offer to shareholders. Such deals are usually structured by agreement and often face smoother regulatory and integration processes.
  • Hostile takeover: Management opposes the acquisition. The bidder may use a tender offer, buy shares on the open market, or wage a proxy fight to change board composition and force approval.
  • Reverse takeover (reverse merger): A private company acquires a publicly listed shell company to achieve a public listing without a conventional initial public offering. It can also describe situations where a smaller acquirer effectively takes control of a larger target.
  • Backflip takeover: A less common structure in which the acquiring company becomes a subsidiary of the acquired company, often used for tax, regulatory, or branding reasons.

Each type implies different negotiation dynamics, timeline pressures, and legal requirements. For example, hostile bids often trigger rapid public campaigns and regulatory scrutiny, while friendly transactions emphasize cooperative integration planning.

Motives, effects, and stakeholders

Companies pursue takeovers for several reasons: to gain scale and market share, acquire new technologies or talent, diversify products or geographic reach, realize cost or revenue synergies, or obtain tax advantages. Outcomes affect shareholders, employees, customers, suppliers, and creditors. Shareholders may benefit from premium offers, but employees may face restructuring and cultural change. Regulators examine potential harm to competition and investors.

Regulation and defensive measures

Takeovers are governed by securities laws, corporate law, and competition (antitrust) rules. Targets adopt defensive measures—called shark repellents—to resist unwanted bids: poison pills (shareholder rights plans), staggered boards, supermajority voting clauses, and golden parachutes for executives. Courts and regulators balance directors' duties to secure the best value for shareholders with protections against management entrenchment.

Successful takeovers require careful valuation, clear strategy for post-deal integration, and attention to legal and cultural issues. They remain a fundamental mechanism for corporate change, shaping industries through consolidation, renewal, and competition.
