What is the difference between a merger and an acquisition?
Legally: in a merger, two corporations combine and at least one of them ceases to exist as a separate entity. In an acquisition, the buyer purchases the target’s shares or assets, and both entities may continue to exist, with the target as a subsidiary.
Commercially, the line is blurrier and mostly rhetorical. Merger of equals describes a combination where neither side pays a control premium and governance is shared; genuine examples are rare, and most transactions announced with merger language have an identifiable acquirer whose shareholders end up in control. The word merger survives in deal-speak because it is kinder to the acquired company’s employees, customers, and pride. The economics do not read press releases.
For the broader landscape of how these transactions work, from valuation through closing, the firm’s mergers and acquisitions overview is the parent to this page.
The three structures that actually matter in private deals
When a private company is sold, the deal takes one of three legal forms, and the choice moves real money.
| Structure | What transfers | Why parties choose it | Watch for |
|---|---|---|---|
| Stock purchase | The shares; the company moves whole, liabilities included | Simple continuity: contracts, licenses, and employees stay in place. Sellers usually prefer it for tax treatment | Buyer diligence goes deep because history transfers; escrows and indemnities carry the risk |
| Asset purchase | Selected assets and liabilities, item by item | Buyers cherry-pick and leave unknown liabilities behind; a stepped-up tax basis in the assets | Often worse tax for sellers of C corporations; contract-by-contract consents can be heavy |
| Statutory merger | Entities combine by operation of law | Binds all shareholders once the required majority approves; clean way to cash out a spread-out cap table | Dissenters may have appraisal rights; structure choice, forward or triangular, drives tax and contract outcomes |
The workhorse variant in company sales is the reverse triangular merger: the buyer forms a shell subsidiary, the shell merges into the target, and the target survives as a wholly owned subsidiary of the buyer. The target’s contracts and licenses generally stay put because the entity never disappears, and every shareholder is bound once the vote clears. When a buyer’s letter of intent specifies structure, it is negotiating tax and risk allocation in advance, which is one reason structure belongs in the price conversation from the first term sheet.
Why the distinction matters to a founder
Three practical consequences follow from structure, and none of them show up in the headline number.
Tax. A stock sale is generally taxed once, at the shareholder level, at capital gains rates. An asset sale by a C corporation can be taxed twice, once inside the company and again on distribution. The same enterprise value can produce materially different after-tax proceeds depending on the form, which is why the structure line in a term sheet is a price term wearing a disguise.
Liabilities and consents. In a stock deal the history goes with the company, so buyers respond with heavier diligence and indemnification packages, the machinery of reps and warranties, escrows, and survival periods. In an asset deal the buyer leaves unknown liabilities behind but must move every contract that matters, and change-of-control or assignment consents from customers and landlords become the critical path.
Shareholder mechanics. Merger structures can require a minority holder to accept a deal the majority approved, subject to appraisal rights. Stock purchases need each seller’s signature. For a founder with a clean cap table this is academic; with option holders, angels, and departed co-founders on the register, it decides how the deal actually closes.
Questions founders ask
What is the difference between a merger and an acquisition?
A merger combines two companies into one legal entity; an acquisition is a purchase in which the target continues as a subsidiary or is absorbed. Most deals called mergers are acquisitions with a diplomatic name.
What are the three main deal structures in a private company sale?
Stock purchase (shares transfer, company moves whole), asset purchase (buyer selects assets and liabilities), and statutory merger (entities combine by law, binding all shareholders once approved).
What is a reverse triangular merger?
The buyer’s shell subsidiary merges into the target, which survives as a wholly owned subsidiary. Contracts and licenses stay intact while ownership changes, and the vote binds all shareholders.
Does the merger vs. acquisition distinction matter to a founder?
The label does not; the structure does. Stock versus asset changes taxes and liabilities, and merger mechanics decide whether minorities can be swept in. Structure is a price term and gets negotiated like one.
