The phrase mergers and acquisitions gets thrown around as if the two words meant the same thing. They do not. A merger blends two companies into one; an acquisition is one company buying another. The distinction shapes who ends up in control, how the deal is paid for, and whether the target's board is a partner or an obstacle. When two companies join forces, the headlines usually say "mergers and acquisitions," or M&A. But a merger and an acquisition are different kinds of deals, and the difference tells you a lot about who holds the power. Here is a plain-English guide. ## A merger: combining into something new In a merger, two companies, often of roughly similar size, agree to combine into a single new entity, [as Corporate Finance Institute explains](https://corporatefinanceinstitute.com/resources/valuation/merger-vs-acquisition/). Both sets of shareholders sign off, the businesses typically operate under a new name, and leadership is usually drawn from both sides. Shares in the old companies are exchanged for shares in the combined one. The framing is partnership, sometimes called a "merger of equals," with power shared rather than concentrated. ## An acquisition: one company takes over another In an acquisition, one company, the acquirer, buys another, the target. The acquirer takes control, generally by purchasing a majority of the target's shares, and the target is folded in as a subsidiary or ceases to exist as an independent company. No new entity is created; ownership simply changes hands. Acquisitions can be friendly or hostile, which is where the target's board becomes central. ## Friendly versus hostile Whether a deal is smooth or a fight depends largely on the target's board. In a [friendly takeover, the target's board and management support the deal](https://corporatefinanceinstitute.com/resources/valuation/friendly-takeovers-vs-hostile-takeovers/) and recommend that shareholders accept it, and the two sides negotiate cooperatively. In a hostile takeover, the target's board opposes the bid, so the acquirer tries to go around it. One route is a "tender offer," appealing directly to shareholders to sell their shares, usually at a premium above the market price. Another is a "proxy fight," persuading shareholders to vote out the existing directors and install ones who will back the deal. ## How deals get paid for Acquirers pay in one of three ways: cash, their own shares (stock), or a mix of both. A cash deal is straightforward but uses up money or requires borrowing. A stock deal conserves cash but dilutes the acquirer's existing shareholders by issuing new shares. Big deals often blend the two to balance those trade-offs. ## Why companies do it The motives are familiar. M&A can buy growth far faster than building a business from scratch, add market share, bring in new products, technology or customers, or spread risk across different lines of business. A common justification is "synergies," the idea that the combined company is worth more than the two apart, whether by cutting duplicated costs (overlapping offices, back-office functions) or by selling more (cross-selling to each other's customers). ## Why so many disappoint For all the strategic logic, a large share of deals fail to deliver the value promised. The usual culprits: overpaying, often because the hoped-for synergies were overestimated; culture clashes between two workforces that erode morale and drive away talent; and the sheer difficulty of integrating systems, teams and operations. Big deals can also run into antitrust review, in which competition regulators scrutinize whether the combination would harm consumers and can block it or demand asset sales. ## A few terms worth knowing - **Synergies:** the extra value expected from combining, through lower costs or higher revenue. - **Due diligence:** the detailed investigation a buyer does into a target's finances, contracts, legal exposure and operations before committing, to confirm the price and surface risks. - **Antitrust review:** the examination by regulators of whether a deal would reduce competition too much; large deals that would create a dominant player face the toughest scrutiny. ## The bottom line Strip away the jargon and the distinction is about control. A merger blends two companies and shares power; an acquisition puts one firmly in charge of the other. Knowing which is which, and whether a deal is friendly or hostile, cash or stock, makes the steady stream of M&A news far easier to read, and helps explain why so many grand combinations end up falling short.
