Merger vs Acquisition vs Consolidation: What Is the Difference?
The legal mechanics behind deal headlines: who survives, how shares are exchanged, why most public deals are reverse triangular mergers, and what happens to the name and ticker.
An acquisition is one company buying control of another; a merger is the legal step that combines two companies so that only one survives; a consolidation combines them into a brand-new company. In practice, most public “acquisitions” are carried out through a merger, usually with a subsidiary of the buyer. The merger agreement’s first article names the surviving company and says what each share becomes.
What is the difference between a merger and an acquisition?
“Acquisition” describes the business result: one company ends up owning another. “Merger” describes a legal method under state corporate law. Delaware’s General Corporation Law, where most large US companies are incorporated, puts it this way in section 251(a): two or more corporations “may merge into a single surviving corporation, which may be any 1 of the constituent corporations or may consolidate into a new resulting corporation.”
| Acquisition (stock or asset purchase) | Merger | Consolidation | |
|---|---|---|---|
| Who survives | Both companies; the target becomes a subsidiary (stock purchase) or sells its assets | One of the existing companies | Neither; a new company is formed |
| How shareholders are paid | Buyer pays each seller directly, or pays the company for its assets | Shares convert automatically into cash, buyer stock or both | Both sets of shares convert into shares of the new company |
| Shareholder vote | Not needed for a stock purchase; each holder decides to sell | Usually a majority of outstanding shares of each constituent company | Same as a merger |
| Holdouts | Can keep their shares | Bound by the vote; may have appraisal rights | Bound by the vote |
Under Delaware section 259, once a merger is effective the separate existence of the disappearing company ends, and the survivor takes over all of its assets, rights and debts by operation of law.
What is a reverse triangular merger?
A reverse triangular merger is the standard way public companies are bought today. The buyer forms a new subsidiary (“merger sub”), and merger sub merges into the target. The target survives and becomes a wholly owned subsidiary of the buyer, while the target’s shareholders receive the deal consideration.
The Warner Bros. Discovery agreement with Paramount Skydance, signed February 27, 2026, uses this structure. Section 1.1 provides that merger sub “shall be merged with and into the Company,” that the company continues as the surviving corporation, and that it becomes “a wholly owned Subsidiary of Buyer.” Buyers like the structure because the target’s contracts, licenses and permits stay with the same legal entity.
Forward and two-step mergers
In a forward merger the target merges into the buyer (or into the buyer’s subsidiary) and disappears. Some deals use two steps. Capital One’s purchase of Discover Financial Services, completed May 18, 2025, first merged a Capital One subsidiary into Discover and then, immediately afterward, merged Discover into Capital One, according to Capital One’s 8-K on the closing. Each Discover share converted into 1.0192 Capital One shares.
What is a merger of equals?
A “merger of equals” is a business label for a combination of two companies of similar size, usually paid in stock, with board seats and executive roles shared between them. Legally it is still a merger with a surviving company, or a deal in which both become subsidiaries of a new holding company. One company’s shareholders often end up with slightly more than half of the combined company, and the proxy statement shows the exact split.
A new holding company works much like a consolidation. Skydance Media and Paramount Global completed their combination on August 7, 2025, under a new parent, Paramount Skydance Corporation, whose Class B shares replaced Paramount Global’s on Nasdaq under the new ticker “PSKY.”
What happens to your shares in each type of deal?
In a merger or consolidation, your shares convert automatically at closing into whatever the agreement specifies: cash, shares of the buyer or new company, or a mix. You do not need to tender or vote to be paid, although brokers handle the exchange and paper certificates require a letter of transmittal. Our guide on what happens to your shares when a company is bought covers timing and fractional shares.
In a stock purchase through a tender offer, you choose whether to sell. In Delaware, a buyer that gets enough shares in a qualifying tender offer can complete a second-step merger under section 251(h) without a shareholder vote, and holdouts receive the same price. See how a tender offer works. Cash and stock consideration are taxed differently; how mergers are taxed explains the rules.
What happens to the company name, ticker and employees?
When the target becomes a subsidiary or disappears, its stock is delisted and its ticker retired after closing. The buyer’s ticker continues, unless a new parent is created, as in the Paramount Skydance case. Brands often outlive the legal entity: an acquired company can keep its name as a subsidiary or a product line.
Employees of a target that survives as a subsidiary usually keep the same legal employer. In an asset purchase or a forward merger into the buyer, the employer changes. Pay and benefits promises in the merger agreement are covered in what happens to employees after an acquisition.
Bottom line
To know which kind of deal you are looking at, read Article I of the merger agreement (filed with the target’s 8-K as Exhibit 2.1): it names the merging entities and the survivor, and Article II says exactly what each share converts into. Headlines use “merger” and “acquisition” loosely; the agreement does not.
FAQ
Is a merger better for shareholders than an acquisition?
Neither label decides value. What matters is the consideration per share, the form (cash or stock) and whether the deal closes. Those are set in the merger agreement.
Do shareholders vote on every merger?
Not always. Delaware generally requires approval by a majority of the outstanding shares for a one-step merger, but a merger after a qualifying tender offer under section 251(h) needs no vote, and the buyer’s shareholders often do not vote when it pays cash.
Why do acquired companies keep their names?
In a reverse triangular merger the target survives as a subsidiary, so its legal name, contracts and brand can continue. Whether the brand stays is a business decision by the buyer.
